-
- [ms]: Offer advice to users of PDF who want a table of contents
- at the front of the document.
-
- * doc/groff.texi (ms Document Structure): Move mention of
- pdfjam(1) from here...
- (ms TOC): ...to here, and identify alternatives, including
- gropdf(1)'s `pdfswitchtopage` macro.
-
- * doc/ms.ms (General structure of an ms document):
- (Creating a table of contents): Similar.
-
- Fixes <https://savannah.gnu.org/bugs/?64278>. Thanks to Michał
- Kruszewski for the report.
-

-
- [docs]: Migrate terminology to "scaling unit".
-
- ...from "scaling indicator".
-
- Fixes <https://savannah.gnu.org/bugs/?60957>. Thanks to Ingo
- Schwarze for the discussion.

-2023-05-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [docs]: Revise discussion of fonts.
-
- * doc/groff.texi:
- - Rename node/section "Fonts and Symbols" to "Using Fonts". Add
- giant new introduction, properly establishing terminology.
- - Rename node/section "Changing Fonts" to "Selecting Fonts".
- Shift location of `.fn` and `.sty` register documentation.
- Rewrite presentation of `ft` and `\f`. Discuss typeface
- selection by mounting position and font (or style) name
- together; since arguments to these formatter instructions are
- always interpreted as mounting positions first, it doesn't
- make much sense to me to present them separately, and the new
- introduction provides the necessary background. Tighten
- example. Document that current and previous font selections
- are environment properties.
- - Add several concept index entries.
- - Do more migration from "symbol" and "glyph" names to "special
- character" names.
-
- * man/groff.7 (Using fonts): Introduce new section, synced with
- the renamed node from our Texinfo manual above.
-
- Fixes <https://savannah.gnu.org/bugs/?62973>.
-
-2023-05-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [docs]: Revise "Page Layout" material.
-
- * doc/groff.texi:
- - Recast generally.
- - Describe behavior of `pl` in more detail.
- - Migrate terminology from "scaling indicator" to "scaling
- unit".
- - Stop discussing page margins in the context of the `pl`
- request.
- - Move concept index entries regarding margins from here to
- "Traps".
- - Move discussion of `pn` request to precede `tl` request.
- - Add concept index entries.
- - Recast description of `tl` request. Migrate terminology from
- "justification" to "alignment".
- - Recast description of `lt` request. Describe behavior in more
- detail.
- - Recast description of `pc` request.
- - Add example of `lt` and `tl` usage. Add forward reference to
- "Traps", mentioning page header and footer traps.
-
- Fixes <https://savannah.gnu.org/bugs/?55124>. Thanks to Dave
- Kemper for the report.
-
-2023-05-22 Dave Kemper <saint.snit@gmail.com>
-
- [docs]: Correct minor punctuation, grammar, and spelling issues.
-
- Also remove a couple instances of unnecessarily telling the
- reader to note something.
-
- * doc/groff.texi:
- * man/groff.7.man:
- * man/groff_char.7.man:
- * man/groff_diff.7.man:
- * man/roff.7.man:

- more fixes. --GBR]
-
-2023-04-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [docs]: Attempt to further clarify end-of-sentence detection.
-
- * doc/groff.texi (Sentences):
- * man/roff.7 (Concepts): Do it.
-
- Fixes <https://savannah.gnu.org/bugs/?64091>. Thanks to Ingo
- Schwarze and Dave Kemper for the report.
-
-2023-04-14 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [docs]: Minimally document `tag`, `taga` requests.
-
- * doc/groff.texi (Postprocessor Access):
- * man/groff.7 (Request short reference): Do it.
-
- Fixes <https://savannah.gnu.org/bugs/?62695>.
-
-2023-04-11 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [docs]: Fix typos.
-
- * doc/groff.texi (ms basic information):
- * doc/ms.ms (Basic information): Do it.
-
- Fixes <https://savannah.gnu.org/bugs/?64032>. Thanks to an
- anonymous reporter.
-
-2023-03-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Operators in Conditionals):
- * man/groff.7.in (Conditional expressions): Clarify how the
- output comparison operator is recognized.
-
- Fixes <https://savannah.gnu.org/bugs/?63812>. Thanks to John
- Gardner for the report.
-
-2023-03-06 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Use a better type for symbol hashes.
-
- * bootstrap.conf: Add "stdint" module to ensure that the
- `uintptr_t` type is available.
- * src/include/symbol.h: Include <stdint.h> for `uintptr_t`.
- (class symbol):
- (symbol::hash): Change return type from `unsigned long`, which
- causes build failures on 64-bit MinGW, to `uintptr_t`.
- (symbol::hash): Use a C++ type cast, not a C-style one.
-
- Thanks to Bruno Haible for reporting the build failure in the
- 64-bit MinGW environment, and for suggesting a remedy.
-
-2023-03-06 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [groff]: Revise a test to be more revealing.
-
- * src/roff/groff/tests/initialization_is_quiet.sh: Stop using
- "set -e". Instead use `fail` variable and `wail` function (and
- lowercase names for our internal variables) like many of our
- other tests. If the "unset" shell built-in fails, skip the
- test (prompted by /usr/xpg4/bin/sh on Solaris). Attempt every
- groff locale, with and without compatibility mode initially
- enabled, instead of stopping at the first failure. Report
- standard error and standard output content separately. Use
- groff's `-a` flag to prepare the standard output, for
- readability.
- * PROBLEMS: Document that this test might be skipped rather than
- failing on Solaris. (What actually happens depends on which
- shell you run it with, and we advise a variety of approaches.)
-
- Thanks to Bruno Haible for feedback regarding mysterious
- failures of this test on GNU/Hurd and NetBSD systems.
-
-2023-03-06 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * bootstrap.conf (gnulib_modules): Add "stdbool-c99" per
- recommendation from Bruno Haible.
-
- Fixes build problem on Solaris using Sun compiler.
-
-2023-03-06 Bruno Haible <bruno@clisp.org>
-
- * Makefile.am (AR): Remove hardcoded value. Let Automake use the
- value from config.status.
-
- {Fixes build problem on 64-bit AIX. Problem appears to date
- back to commit 5fec19d453, 2014-08-15. --GBR}
-
-2023-03-06 Bruno Haible <bruno@clisp.org>
-
- * arch/misc/misc.am (shdeps.sed): Rename target from this...
- ($(SH_DEPS_SED_SCRIPT)): ...to this, to work better with make(1)
- on FreeBSD, NetBSD, and AIX.
-
-2023-03-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Discard now-unneeded Autoconf macro and variables.
-
- * configure.ac: Stop calling `GROFF_POPPLER`. Stop populating
- the Automake conditional `HAVE_PDFTOOLS`. Eliminate chatter
- about their availability in the configuration report.
- * m4/groff.m4 (GROFF_POPPLER): Delete.
-
-2023-03-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_URW_FONTS_NOTICE): Adapt wording of notice
- to presence and identity of Ghostscript interpreter command.
- Clarify that it is gropdf(1) specifically that traverses the
- Ghostscript search path reported by its "-h" option.
-
- Continues <https://savannah.gnu.org/bugs/?63808>. Thanks to
- Deri James for the ongoing discussion.
-
-2023-02-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [devpdf]: Revise tests.
-
- * font/devpdf/tests/check-default-foundry.sh.in: Test only the
- base 14 fonts of the PDF standard unconditionally. Test the
- remainder from the set of 35 commonly distributed only if a
- Ghostscript interpreter was detected at configuration time,
- because the latter fonts _must_ be embedded in PDF documents.
- If they're not present, skip the test rather than failing it.
- * font/devpdf/tests/check-urw-foundry.sh.in: Skip test if no URW
- fonts detected at configuration time, rather than failing it.
- * m4/groff.m4 (GROFF_GROPDF_PROGRAM_NOTICE)
- (GROFF_URW_FONTS_NOTICE): Drop warnings of expected test
- failures. The tests no longer fail in the anticipated
- circumstances.
-
-2023-02-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [devpdf]: Generate tests from template files, so we can populate
- the test scripts with information determined at configuration.
- The default foundry test depends on $GHOSTSCRIPT, and the URW
- foundry test on $urwfontsdir.
-
- * font/devpdf/tests/check-default-foundry.sh:
- * font/devpdf/tests/check-urw-foundry.sh: Rename these...
- * font/devpdf/tests/check-default-foundry.sh.in:
- * font/devpdf/tests/check-urw-foundry.sh.in: ...to these.
-
- * font/devpdf/devpdf.am (font_devpdf_default_test)
- (font_devpdf_urw_test): New variables store names of generated
- test scripts.
- (font/devpdf/tests/check-default-foundry.sh):
- (font/devpdf/tests/check-urw-foundry.sh): New targets produce
- test scripts from corresponding .in files.
-
-2023-02-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [devpdf]: Trivially refactor. Rename sed-substitutum [Lat.]
- from "@GROFF_GHOSTSCRIPT_INTERPRETERS@" to "@GHOSTSCRIPT@" for
- clarity and brevity; this is a scalar value containing the
- Autoconf-determined name of the Ghostscript interpreter. It is
- not the same as the replacement that occurs in contrib/pdfmark.
-
- * font/devpdf/devpdf.am:
- * font/devpdf/util/BuildFoundries.pl: Do it.
-
-2023-02-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Stop scraping output of Ghostscript executable with
- "-h" option to attempt to find URW fonts. Fonts that ship with
- Ghostscript are regarded as the "default" foundry, not the URW
- foundry (though they often ultimately originate with URW fonts).
- They are often missing Adobe Font Metric (AFM) files, so it is
- impossible for groff to generate font description files for them
- at build time.
-
- * m4/groff.m4 (GROFF_URW_FONTS_CHECK): Drop `AC_REQUIRE` on
- `GROFF_AWK_PATH`. Drop awk-based scraping of Ghostscript "-h"
- output. Annotate need for sync between this list of
- characteristic font file names and the one in BuildFoundries.
-
- Thanks to Deri James for the ongoing discussions.
-
-2023-02-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: Drop now-redundant explicit
- `GROFF_URW_FONTS_CHECK`. `GROFF_GROPDF_DEPENDENCIES_CHECK`
- `AC_REQUIRE`s it as of commit ec001d2a23, 18 February.
-
-2023-02-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_URW_FONTS_CHECK): When looking for a
- characteristic URW font by its file name, also check for
- "URWGothic-Book" with no file extension. Avoids false negatives
- in URW Type 1 font detection when using Ghostscript 9.53.3.
- Thanks to Deri James for suggesting the test procedure that
- uncovered this flaw.
-
-2023-02-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am (uninstall_groffdirs): Remove "html.mono" and
- "html.node" directories corresponding to HTML version of our
- Texinfo manual.
- * doc/doc.am (uninstall-html): Uninstall HTML version of our
- Texinfo manual more reliably.
-
- Fixes a regression introduced by me in commit c2698aade, 6 April
- {my claim "we're only deleting files with this command, not
- directories" was not correct}.
-
-2023-02-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [doc]: Handle output formats of our Texinfo manual more
- consistently.
-
- * doc/doc.am (install-doc): Add dependency on (Automake
- standard) target 'install-dvi'.
- (maintainer-clean-local): Remove our Texinfo manual in plain
- text format.
- (install-data-local): Add dependency on new target
- 'install-txt'.
- (install-txt): Install our Texinfo manual in plain text format.
- (uninstall-local): Add dependency on new target 'uninstall-txt'.
- (uninstall-txt): Uninstall our Texinfo manual in plain text
- format.
-
- Thanks to T. Kurt Bond for noticing the discrepancy.
-
-2023-02-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (install-pdf-local, install-html-local): Enable
- rules to work in out-of-tree builds.
-
-2023-02-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (uninstall-hook): Drop dependency on
- "uninstall_mom"; this is not the appropriate place to declare
- it, and "uninstall_groffdirs" already depends on it in mom's
- Automake file.
-
-2023-02-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tests]: Have more tests report output.
-
- * src/roff/groff/tests/ab_works.sh:
- * src/roff/groff/tests/handle_special_input_code_points.sh:
- * src/roff/groff/tests/initialization_is_quiet.sh:
- * src/roff/groff/tests/msoquiet_works.sh:
- * src/roff/groff/tests/soquiet_works.sh:
- * tmac/tests/an-ext_MR-works.sh:
- * tmac/tests/an_MR-works.sh: Do it.
-
-2023-02-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tests]: Prevent failures when $GROFF_ENCODING is set.
-
- * src/roff/groff/tests/ab_works.sh:
- * src/roff/groff/tests/handle_special_input_code_points.sh:
- * src/roff/groff/tests/initialization_is_quiet.sh:
- * src/roff/groff/tests/msoquiet_works.sh:

- * tmac/tests/an-ext_MR-works.sh:
- * tmac/tests/an_MR-works.sh:
- * tmac/tests/an_font-remapping-does-not-affect-titles.sh: Unset
- $GROFF_ENCODING before running test because preconv(1) confounds
- these tests.
-
- Thanks to Alexis for reporting this problem.
-
-2023-02-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [ms]: Rename test.
-
- * tmac/tests/s_no-excess-space-around-displays.tmac: Rename...
- * tmac/tests/s_no-excess-space-around-displays.sh: ...to this.
- * tmac/tmac.am (tmac_TESTS): Update.
-
-2023-02-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [gropdf]: Revise tests to run unconditionally, rather than
- configuring them away at build time, which can cause a
- distribution archive to be incorrectly structured. Update
- configuration notices when optional dependencies are absent.
-
- * font/devpdf/devpdf.am (font_devpdf_TESTS): Remove `USE_GROPDF`
- and `HAVE_URW_FONTS` conditionals.
- * m4/groff.m4 (GROFF_GROPDF_PROGRAM_NOTICE):
- (GROFF_URW_FONTS_NOTICE): Warn reader that a gropdf test failure
- is to be expected.
-
- Fixes <https://savannah.gnu.org/bugs/?63824> (2/2).
-
-2023-02-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grohtml]: Revise tests to check for requisite programs at test
- time and skip if not found, rather than configuring them away at
- build time, which can cause a distribution archive to be
- incorrectly structured.
-
- * m4/groff.m4: Annotate requisite program list since we're
- violating the DRY principle.
- * src/roff/groff/groff.am (groff_TESTS): Populate
- unconditionally.
-
- * src/roff/groff/tests/html_works_with_grn_and_eqn.sh:
- * src/roff/groff/tests/smoke-test_html_device.sh: Check for
- requisite programs and skip test if any are not found.
-
- Fixes <https://savannah.gnu.org/bugs/?63824> (1/2).
-
-2023-02-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man pages]: Define page-local `MR` fallback.
-
- [man pages]: Provide page-local fallback definition of new `MR`
- macro. I didn't think I was going to have to do this, but the
- premier site on the web for viewing Linux man pages, Michael
- Kerrisk's man7.org, has been pulling snapshots of the pages
- themselves without upgrading the underlying macros, and so man
- page cross references set with `MR` are getting lost in its
- presentations. (I acknowledge: Ingo Schwarze warned me
- something like this could happen.) This definition is intended
- as a stopgap measure only. I want to revert this after groff
- 1.23 is released and has spread to some reasonable degree.

-2023-02-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/tests/an_TS-do-not-keep-tables-when-cR-set.sh: Improve
- portability of script by using shell constructs instead of the
- nonstandard GNU coreutils 'seq' utility. Resolves test failure
- on Solaris 10.
- * HACKING: Document this problem.
-
-2023-02-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_MAKE_DEFINES_RM): Test the make(1) in the
- environment variable $MAKE if defined, not a literal "make".
- Required on (some) Solaris 10 configurations where traditional
- make(1) is not installed but GNU make is installed as "gmake".
-
-2023-02-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/tests/latin2_works.sh: Fix missing backslash in printf.
- Solaris printf(1) was sensitive to this error; macOS and GNU
- printf were not. Fixes a test failure on Solaris 11.
-
-2023-02-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/tests/regression_savannah_58153.sh: Improve
- portability. Avoid the unpredictability of implementations when
- putting backslashes inside a groff-piped printf shell command
- inside a here document inside a command substitution by changing
- the groff escape character to something meaningless to the shell
- and to printf ('@'). Fixes a test failure on Solaris 11.
-
-2023-02-18 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/Foundry.in: Recognize URW foundry replacements for
- Helvetica Bold-Oblique and Helvetica Oblique under the file
- names "NimbusSans-BoldItalic.t1" and "NimbusSans-Italic.t1",
- respectively.
-
-2023-02-18 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (uninstall-pdf): Clean more fastidiously; try to
- remove the configured `pdfdocdir` in the event it is empty, but
- do not fail if it isn't. (It can be a directory shared with
- other groff components; we don't know in what order the
- uninstall targets will serialize, but the last one run should
- succeed.)
-
-2023-02-18 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Detangle "pdfroff" and "gropdf" configuration (2/2).
-
- * m4/groff.m4: Give pdfroff its own Autoconf macros to handle
- dependency checking, build objectives, and user notice.
- (GROFF_PDFROFF_DEPENDENCIES_CHECK): New macro requires
- `GROFF_AWK_PATH` and `GROFF_GHOSTSCRIPT_PATH`, determines
- whether pdfroff can be used at build time, and (if not)
- constructs part of message to be shown to user explaining why.
- (GROFF_PDFROFF_PROGRAM_NOTICE): New macro requires
- `GROFF_PDFROFF_DEPENDENCIES_CHECK` and emits message if needed.
- (GROFF_GHOSTSCRIPT_AVAILABILITY_NOTICE): Drop mention of impact
- on pdfroff since its dedicated notice covers this now.
- * configure.ac: Call the new macros at appropriate times.
- Produce a new Automake macro, `USE_PDFROFF`, to replace
- inapposite use of `USE_GROPDF` in pdfmark.am.
- * contrib/pdfmark/pdfmark.am: Use `USE_PDFROFF` instead of
- `USE_GROPDF`.

-
- [build]: Detangle "pdfroff" and "gropdf" configuration (1/2).
-
- * m4/groff.m4 (GROFF_GROPDF_DEPENDENCIES_CHECK): Add
- `AC_REQUIRE`ment on `GROFF_URW_FONTS_CHECK`. Per discussion
- with Deri James, if _either_ Ghostscript or the URW fonts are
- avilable, gropdf will be fully functional, consequent to commit
- d5515, 22 June. Drop dependency on awk; it is used only at
- configuration time (in an Autoconf macro) and since Savannah
- #62775 was resolved (19 September), it has not been strictly
- necessary. (It is useful for searching more locations for URW
- fonts, but several others are searched even if it is absent.)
- Stop populating notice text here, instead moving it...
- (GROFF_GROPDF_PROGRAM_NOTICE): ...here, since it no longer needs
- to be dynamically constructed.
-
- Continues <https://savannah.gnu.org/bugs/?63808>. Thanks to
- Deri James for the continued discussion.

-2023-02-18 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [gropdf]: Don't run automated tests if 'gropdf' will be
- operating with reduced function. If neither Ghostscript nor the
- URW fonts are available at configuration time, there is no point
- testing for successful build-time population of the font
- descriptions for the default and URW foundries.
-
- * font/devpdf/devpdf.am (font_devpdf_TESTS) [USE_GROPDF]: Run
- "check-default-foundry" only if gropdf is fully functional.
- (font_devpdf_TESTS) [USE_GROPDF && HAVE_URW_FONTS]: Run

-
- [gropdf]: Revise tests to be foundry-focussed.
-
- * font/devpdf/tests/basic-fonts-present.sh: Stop trying to match
- font descriptions in the "devps" directory with ones in
- "devpdf"; instead, test whether "BuildFoundries" did its job.
- Test for font descriptions corresponding to the full 35
- PostScript Level 2 font repertoire, plus groff's "EURO".
- * font/devpdf/tests/urw-fonts-present.sh: Drop stale comment and

-
- [man]: Tweak fix to Savannah #63768.

-
- [ms]: Port a test to Solaris 11 sed.

-2023-02-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/tests/\
- device_control_escapes_express_basic_latin.sh: Use printf(1),
- which is often a shell built-in command, more consistently.
- Double backslashes intended as literals in the format string,
- and single-quote format strings using them. Fixes test failure
- seen on Solaris 11 with GNU Bash 4.4 and ksh 93u+ (2012-08-01).

-
- * configure.ac: Add Automake conditional, `HAVE_GHOSTSCRIPT`, so
- that we can populate the list of PDF device font tests
- dynamically. Call new macro
- `GROFF_GHOSTSCRIPT_AVAILABILITY_NOTICE`. Call
- `GROFF_GHOSTSCRIPT_VERSION_NOTICE` after it, but before
- `GROFF_URW_FONTS_NOTICE`.
- * m4/groff.m4 (GROFF_AWK_NOTICE): New macro produces warning if
- no awk could be found. This reduces gropdf functionality, but
- so do missing URW fonts, so we report this problem separately.
- Report the names under which we sought it, since there's a
- configure script option for that.
- (GROFF_GHOSTSCRIPT_AVAILABILITY_NOTICE): New macro explains
- consequences of missing optional dependency on Ghostscript
- program: reduced grohtml functionality, nonfunctional pdfroff.
- Report the names under which we sought it, since there's a
- configure script option for that.
- (GROFF_CHECK_GROPDF_PROGRAMS): Better characterize gropdf's
- reduced function, pointing out the ways in which it would be
- more useful if the dependencies were met. Also simplify the
- computational grammar.
- (GROFF_URW_FONTS_NOTICE): Identify 'U' as the foundry name
- gropdf uses for the URW fonts. Confirm continuing availability
- of most recent URW fonts release; bump date.
- * font/devpdf/devpdf.am: Test availability of "basic" (PDF base
- 14) fonts (plus groff's "EURO") if either Ghostscript or URW
- fonts are available. Test availability of URW fonts (35) only
- if Ghostscript _and_ the URW fonts were found at configuration
- time.
-
- Fixes <https://savannah.gnu.org/bugs/?63808>. Thanks to Deri
- James for the report and extremely helpful pseudocode.
-

-
- * m4/groff.m4 (GROFF_GHOSTSCRIPT_VERSION_CHECK,
- GROFF_URW_FONTS_NOTICE): Add macro dependency on
- `GROFF_GHOSTSCRIPT_PATH`, which should have been there already.
- (GROFF_GROHTML_PROGRAM_NOTICE): Add macro dependency on
- `GROFF_CHECK_GROHTML_PROGRAMS`, which should have been there
- already.
-
- (GROFF_CHECK_GROHTML_PROGRAMS, GROFF_PNMTOOLS_CAN_BE_QUIET):
- Move `AC_REQUIRE` expansions to precede shell variable
- assignments (after checking that the required macros don't
- clobber the assignments we're making).
-
-2023-02-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/tests/basic-fonts-present.sh: Revise test again,
- per feedback from Deri James. Even without Ghostscript or URW
- fonts available, gropdf can generate valid PDF documents; it
- simply can't embed fonts in general (without further
- arrangements made on the host system), which means it is
- restricted to the PDF base 14 fonts. That's enough for many
- purposes, including generating our compiled man pages document
- {with minor degradations to the typeface lists in gropdf(1) and
- grops(1)}. Drop the 'gs' command check, which also didn't check
- for the name of the Ghostscript interpreter determined by the
- "configure" script. Replace dynamically generated font list
- with a static one (the base 14 fonts plus groff's EURO).
-
-2023-02-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/tests/basic-fonts-present.sh: Revise test.
- Improve explanation of why we're looking for the gs(1) command
- in a font availability test. Prefix diagnostic output with name
- of test script. Perform a search for the 'ps' device font
- descriptions that will work in more build scenarios (i.e., don't
- assume an out-of-tree build taking place in an immediate
- subdirectory of the source). Distinguish failure to find the
- font descriptions from a failure to locate the 'gs' command,
- skipping the test in both scenarios. Reduce noise in output.
- * m4/groff.m4 (GROFF_CHECK_GROPDF_PROGRAMS): Revise warning
- issued when awk and Ghostscript are unavailable; gropdf will not
- be completely inoperative. Characterize its reduced function.
-
- Thanks to Deri James in <https://lists.gnu.org/archive/html/\
- groff-commit/2023-02/msg00089.html> for prompting me to take a
- another look at this.

-
- * tmac/tests/latin2_works.sh:
- * tmac/tests/latin5_works.sh:
- * tmac/tests/latin9_works.sh: Port to work around macOS's
- apparently POSIX non-conforming 'od' command. Use single-byte
- octal output format instead of "character", and update test
- expectations accordingly. Apparently gratuitously, macOS also
- puts more spaces after the octal address field when using this
- output format.
- * HACKING: Document, and elaborate upon, this problem.
-
-2023-02-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [mdoc]: Port a test to work with macOS sed.
-
- * tmac/tests/doc_heading-font-remapping-works.sh: Put semicolons
- between commands and closing braces in sed script. Put each of
- multiple closing braces on a separate input line, because macOS
- doesn't accept them otherwise. Resolves test failure observed
- on macOS.
- * HACKING: Document the closing brace sequence problem.

-
- * src/roff/groff/tests/\
- some_escapes_accept_newline_delimiters.sh: Weaken regexes in two
- test cases to accommodate excessive output from macOS's 'od'

- * HACKING: Add section "Writing Tests" and document the above
- since this is the second time I've cracked my shin on this.
-
-2023-02-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/tests/basic-fonts-present.sh: Skip test if 'gs'
- command not available. The test is to ensure that gropdf will
- produce sound documents using the base fonts from PostScript,
- but since gropdf requires Ghostscript to do this (as noted in
- our "./configure" messages), it makes no sense to validate font
- availability if the program is absent. Resolves test failure
- seen on macOS with minimal dependencies installed.

- Switch to using system's assert.h header file. It is futile to
- attempt to preserve compatibility with ISO C90 systems by
- providing a bespoke predicate-reporting assert() (a C99 feature)

- that `static_assert` remains defined so that gnulib can use it.

-
- [tbl]: Fix bugs using boxes or vertical rules at table edges on
- nroff devices, particularly when combined with region or column
- expansion.
-
- * src/preproc/tbl/table.h (class table): Add `GAP_EXPAND`
- enumeration constant. James Clark seems to have designed GNU
- tbl carefully to avoid distinguishing region expansion from
- column expansion in a categorical way, but I needed a way for
- formatting-time logic to know which was in use. (Column
- expansion, the "x" modifier, expands columns--i.e., text.
- Region expansion expands [or compresses] the _gaps_ between
- columns.)
- * src/preproc/tbl/main.cpp (process_options): Set `GAP_EXPAND`
- flag in table if "expand" region option seen.
- * src/preproc/tbl/table.cpp: Add new macro `LEFTOVER_FACTOR_REG`
- to name a new roff register for the remainder of gap-expansion
- space when the amount of space available for expansion is
- divided by the number of gaps.
- (table::compute_overall_width): If _not_ expanding a table in
- either respect and in nroff mode, reduce line length by 1n for
- each of any left and right border (because the vertical lines
- eat character cells). This prevents bordered or boxed tables
- from being overset even when they use neither expansion feature.
- (table::compute_separation_factor): If gap-expanding a table,
- store any remainder from the division used to compute the
- separation factor into the new `LEFTOVER_FACTOR_REG`.
- (table::compute_column_positions): Insert that remainder into
- the gap before the last (rightmost) column of the table. This
- _could_ be done more elegantly by spreading each en in a
- symmetric way across a subset of the gaps. (It is necessarily a
- subset by the pigeonhole principle.) But it didn't seem worth
- the effort for a feature (region expansion) that few users
- employ. (Usually what you want is the "x" column modifier.)
- Alternatively, "forget it, Jake--it's a terminal emulator".
-
- * src/preproc/tbl/tbl.am (tbl_XFAIL_TESTS): Remove now-passing
- tests.
-
- Fixes <https://savannah.gnu.org/bugs/?63640> and
- <https://savannah.gnu.org/bugs/?63749>.
-
-2023-02-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/tbl/table.cpp (table::compute_column_positions):
- Stop multiplying the gaps at the left and right edges of a table
- {which occur when it is boxed or has a leading and/or trailing
- vertical line} by the column separation factor. Only interior
- column gaps should be spread. This change prevents tables using
- the "expand" region option from being overset (exceeding the
- line length), but might not (yet) fully expand to that length on
- low-resolution devices due to integer roundoff.

-
-2023-02-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Refactor.
-
- * src/preproc/tbl/table.cpp:
- * src/preproc/tbl/table.h: Rename `compute_expand_width` to
- `compute_overall_width`, since this member function is used on
- _all_ tables, not just those undergoing column or gap expansion.
- For instance, in a post-groff 1.22.4 development, it throws a
- diagnostic if an unexpanded table overruns the line length.
- * src/preproc/tbl/table.cpp (table::compute_widths): Update call
- site of `compute_overall_width`.
- * src/preproc/tbl/table.cpp: Split the roff register behind the
- `EXPAND_REG` C++ preprocessor macro into two, adding
- `AVAILABLE_WIDTH_REG`. Annotate the distinction.
- (compute_overall_width): Annotate. Move and conditionalize
- logic so as not to produce as much unnecessary roff output.

-
-2023-02-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/tbl/table.cpp (table::compute_column_positions):
- If a table has "left separation" (it is boxed, or has a vertical
- rule on the left-hand side), increase the first column's start
- register value by 1n, for symmetry with the right-hand size.

-
- [tbl]: Refactor handling of vertical lines in format. Validate
- input more strictly. Add diagnostics when vertical lines are
- redundant with box borders.
-
- * src/preproc/tbl/main.cpp (process_format): Shift diagnostic
- about excess vertical lines in a sequence at the beginning of a
- row description to later, after the first proper column
- descriptor has been interpreted. Normalize a sequence of more
- than two consecutive vertical lines to 2 when they occur at the
- beginning of a row description. Unconditionally update
- `list->vline` and reset `vline_count` once we start looking for
- modifiers, since we know we've finished any sequence of vertical
- lines, and at the end of a row definition. Rename and retype
- loop variable int `success` to Boolean
- `is_valid_modifier_sequence`. Drop now-invalid assertion.
- * src/preproc/tbl/table.cpp (table::add_vlines): Throw new
- diagnostics when vertical lines are redundant with box borders.
- Add assertion to ensure we got a valid vertical line value (0,
- 1, or 2) from `process_format`. Throw these only once per table
- format, not for every row.

-
- [grohtml]: Fix misleading diagnostic message.
-
- * src/preproc/html/pre-html.cpp (main): The suggestion should be
- to re-run the formatter (groff, troff), not "pre-grohtml", with

-
- [tbl]: Really fix Savannah #63449.
-
- * src/preproc/tbl/main.cpp (process_format): "Or" on the
- `HAS_TOP_VLINE` flag if the format specification begins with a
- "|"; the beginning is a separate state in the FSM used to parse
- the description. I missed it in commit 0e93ab4102, 1 December.

-
-2023-01-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-ext.tmac: Move the saving of the hyphenation mode from
- the "top level" to...
- (mY): ...this new macro.
- (SY, mQ, MR): Call `mY` before disabling hyphenation.
-
- Problem introduced by me in commit 096c2f0567, 16 February.
- "an-ext.tmac" gets sourced by "an.tmac" before any
- command-line setting of the `HY` register is handled, so (for
- groff) the stored hyphenation mode was the default for the
- language, not reflecting user disablement. The synopsis macros,
- which do not have an alternate implementation in "an.tmac" for
- leverage of groff features, were causing hyphenation to be
- resurrected (after `YS`) even if the user had disabled it.
- Saving the hyphenation mode anew upon entry to these macros is
- arguably inefficient, but it is more correct since a man page
- could conceivably manipulate the automatic hyphenation mode
- {even if that's not recommended outside of tbl(1) text blocks}.
-
-2023-01-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man]: Add regression test for hyphenation getting wrongly
- restored by `YS`, `ME`, `UE`, and `MR` macros.
-
- * tmac/tests/an_HY-register-works.sh: Do it.
- * tmac/tmac.am (tmac_TESTS): Run test.
-
-2023-01-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/mdoc/doc-common (Sh, Ss): Narrow scope of font remappings
- lexically and restrict remapping to the heading font family (if
- any) to avoid undesired remapping of fonts in page headers if,
- say, a (sub)section heading begins just prior to a page
- break--which is ugly anyway and should be avoided, but the
- package has no keep macros and solving that problem in an
- automatic way promises to be complex.
-
-2023-01-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an.tmac (MT, UR): Throw style warning if macro called
- without (exactly one) argument.
-
-2022-12-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (doc/groff-man-pages.pdf): Set (sub)section
- headings in Helvetica bold in compiled man pages, as a test and
- demonstration of the `HF` feature's application to both man(7)
- and mdoc(7) documents.
-
-2022-12-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [mdoc]: Support `HF` string.
-
- * tmac/doc.tmac (initialization): Add logic supporting `HF`
- string just as our man(7) implementation does. If the font name
- ends with `B` (as the default does), set
- `doc-remap-I-style-in-headings` register and extract font
- family, which can be empty (as is the default).
- * tmac/mdoc/doc-common (Sh, Ss): If
- `doc-remap-I-style-in-headings` register set, perform (and
- unwind) font remapping of italic to bold-italic face.
- * tmac/mdoc/doc-ditroff:
- * tmac/mdoc/doc-nroff: Define `doc-Sh-font` in terms of `HF`.
-
- * tmac/tests/doc_heading-font-remapping-works.sh: Test it.

-
- [tmac]: Revise "fallback" character definitions in several
- respects for Unicode characters from General Punctuation block.
-
- * tmac/fallbacks.tmac: Comment out fallbacks for U+200B, U+2010,
- U+2011, and U+201[89CD], due to ineffectuality or apparent groff
- bugs. Redefine U+2012 fallback to include hair space (\^)
- around synthetic figure dash. Redefine U+2016 to use `\[ba]`
- special characters instead of ordinary `|` characters to dodge
- possible character translations by user.

-
- [tests]: Fix potential problem(s) in trap handler.
-
- * src/roff/groff/tests/smoke-test_html_device.sh: Move call of
- `cleanup` function from end of script to after the tests that
- generate temporary files have been run, and before script
- possibly exits with status 77 to skip some checks. Within trap
- handler, mask trapped signals while running handler.
- (cleanup): Reset trap dispositions to default after removing
- files; once the temporary files are gone, we no longer need a
- trap handler. One might already be running however, and this
- ensures that its "suicide" ("kill -s INT $$") will succeed.

-
-2022-12-17 G. Branden Robinson <g.branden.robinson@gmail.com>

-2022-12-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an.tmac (TH): Relocate `an-break-body-text` trap to be
- one half-inch above footer (instead of twice the footer
- distance). I reason that anyone who customizes `FT` is doing so
- to overprint some kind of material at the bottoms of pages, or
- simply to make the margin larger. (One then wonders why we
- don't have an `HD` register for the top.) Also remove register
- when done with it.
- * tmac/groff_man.7.man.in (Options) <FT>: Document this.
-
-2022-12-15 G. Branden Robinson <g.branden.robinson@gmail.com>

-
- * tmac/andoc.tmac (reload-man): Unplant `doc-break-body-text`

- no confidence that will remain true forever.
-
-2022-12-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an.tmac (initialization): Fix problem with `FT` register
- validation. Small but valid values were being rejected due to
- inappropriate use of scaling operator. Also throw user a bone
- by expressing what size '1v' is for the output device, in basic
- units.
-
-2022-12-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man, mdoc]: Fix Savannah #63500. Support use of `P` (initial
- page number) register when batch rendering, regardless of
- switching macro packages between man(7) and mdoc(7) or setting
- of `C` (continuous numbering) register. (`P` without `C` means
- "start numbering each rendered document at \n[P]".)
-
- * tmac/an.tmac (an-end): Call `an*break-page-with-new-number`
- instead of invoking `bp`.
- (an*break-page-with-new-number): If `P` is set and `C` is not,
- use value of `P` as the next page number.
- (TH): If `C` register is set, remove `P` register after ending a
- previous document.
- (initialization): If `P` is set, assign the page number using
- the `pn` request if the transition to the first formatted page
- has not yet occurred; otherwise update page number register `%`
- directly. Also ignore it with diagnostic if `ps4html` register
- {for grohtml's internal use} is set. Add explanatory comment.
-
- * tmac/mdoc/doc-common (Dd): If `C` register is set, remove `P`
- register after ending a previous document.

- [troff]: Trivially refactor. Rename class `constant_reg` to
- `readonly_text_register`. Say "readonly" instead of "const" to
- try to avoid confusion with C++ constness. Say "text" because
- this class is _mostly_ used for interpolation of string-valued
- registers like the version registers `.x`, `.y` and `.Y`.
- Nevertheless there are some abuses (apparently because the
- constructors for register classes don't accept integer
- parameters for initialization--why?).
-
- * src/roff/troff/input.cpp (top level)
- (readonly_text_register::readonly_text_register)
- (readonly_text_register::get_string)
- (main, init_registers, init_requests): Do it.

- interpolations--except where we can't: see Savannah #63470.
-
-2022-12-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an.tmac (R): Drop macro definition, which implements a
- hack for people who try to use "R" as a font style macro. This
- doesn't seem to happen much in actual practice (though perhaps
- the diagnostic this hack produces is responsible for suppression
- of the mistake). Retaining it interferes with the

-
- * tmac/an-ext.tmac: Remove groff-feature-dependent code for
- hyperlink management, greatly reducing the size of the file,
- which we permissively license and encourage people to copy
- around. Drop register definitions corresponding to
- groff-specific output device names. Drop definition and use of
- `mL` and `mR` strings for angle brackets; no observable change
- on non-groff formatters. Recognize `mG` register to enable
- testing of these macros even if the formatter is groff.
- (mV): Radically simplify. This internal "back-end" for `MT` and
- `UR` now just stores its argument in a string, `m1`.
- (mQ): Radically simplify. This internal "back-end" for `ME` and
- `UE` now just disables automatic hyphenation, formats the saved
- `m1` string between angle brackets, suffixes it with the
- optional argument, and restores automatic hyphenation.
- (UR, MT): Call `mV` with one argument, not nine.
- (UE, ME): Call `mQ` with one argument, not nine.
-
- * tmac/tests/an-ext_MR-works.sh: Add test of this file's
- simplified `MR` implementation.
- * tmac/tests/an-ext_MT-works.sh:

- * tmac/tests/an_MR-works.sh:
- * tmac/tests/an_MT-works.sh:
- * tmac/tests/an_UR-works.sh: Add tests for valid HTML formatting
- of hyperlinks, which experience shows is a bit fragile in the
- face of diversion manipulation and output line continuation.
-
- * tmac/tmac.am (tmac_TESTS): Run new tests.
-
-2022-12-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-ext.tmac: Support `mG` register: clear it to force the
- loading of this file's macros even if they have an
- implementation in tmac/an.tmac and the formatter claims groff
- compatibility. This is to ease these macros' testing under
- groff and keep the implementations here simple.
- * tmac/an.tmac: Initialize `mG` register to 1 if not set on
- command line.
-
-2022-12-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-ext.tmac: Initialize `mX` register.
-
-2022-12-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-ext.tmac: Define `mC` string (constant-width typeface
- used by `EX`/`EE` macros) as `R` in nroff mode. Thanks to
- Russ Allbery for prompting me to think more about the
- limitations of Solaris troff. Implementations do varying
- things with the "previous" font restored by `\fP` or an
- unargumented `.ft` if a requested font is not found.

- [tbl]: Fix Savannah #63449.
-
- * src/preproc/tbl/table.h (class table): Add new enumeration
- constants for use with `flags` member variable: `HAS_TOP_VLINE`
- and `HAS_TOP_HLINE`, which track properties of the table.
- Unlike others, these have no correspondence to table region
- options.
- * src/preproc/tbl/main.cpp (process_format): Add new local
- Boolean to track whether we're interpreting a format for the
- first row. Use this to "or" on the `HAS_TOP_VLINE` or
- `HAS_TOP_HLINE` flags if "|" or [_-] are encountered in the
- first row's format, as appropriate.
- (process_data): "Or" on `HAS_TOP_HLINE` if a single or double
- horizontal line is used as the first row's data.
- * src/preproc/tbl/table.cpp (do_top): On nroff mode devices, add
- one vee of space above the table if we're going to be drawing an
- unintersected vertical rule above the table's top.

- (table::do_bottom): Produce roff output that is more readable,
- for maintainability. Indent control lines inside macro
- definitions. Standardize form of `if`, `ie`, and `el` requests.
- Some output will not be indented because it is produced within
- narrowly-scoped C++ functions (set_troff_location,
- table::print_single_hline, table::print_double_hline,
- table::do_row), I haven't verified that each one is called from
- a consistent troff indentation level, and I'm not sure it's a

- [tbl]: Fix Savannah #61909.
-
- * src/preproc/tbl/table.cpp (SAVED_INTER_WORD_SPACE_SIZE)
- (SAVED_INTER_SENTENCE_SPACE_SIZE): Add new preprocessor macros.
- (block_entry::do_divert): Restore saved inter-word and
- inter-sentence space when formatting a text entry.
- (table::init_output): When a table region begions, save the
- values of inter-word and inter-sentence space. Add request to
- the reset macro to restore saved inter-word and inter-sentence
- space when leaving table region.
- (table::do_top): Set inter-sentence space to be equal to
- inter-word space. This way spaces are "literal" in ordinary
- table extries (but not text blocks).

-
- * src/preproc/tbl/table.cpp: Revert much of commit b69062693's
- {2011-07-20} changes to this file. They were too complex for me
- to understand, and permitted Savannah #60140 to persist (or
- caused it).
- (ROW_START_LINE_REG, ROW_SAVE_LINE_REG, ROW_MAX_LINE_REG)
- (REPEATED_NM_SET_MACRO, REPEATED_NM_SUS_MACRO): Drop
- preprocessor macros.
- (SAVED_NUMBERING_LINENO, SAVED_NUMBERING_SUPPRESSION_COUNT): Add

- (table::init_output, table::print_single_hline)
- (table::print_double_hline, table::define_bottom_macro)
- (table::do_row, table::do_top, table::do_bottom): Drop old
- logic.
-
- (table::init_output): When the table begins, save the current
- line number register `ln` and the count of remaining lines to be
- suppressed (the new `.nn` register). Then suppress numbering
- for the next 2 billion+ lines of output, with a groveling
- apology to the elegance police.
- (table::do_bottom): Restore saved value of `.nn`. If numbering
- was active (even if suppressed), restore it with `nm` request.
- If it wasn't, disable it, in case it was turned on inside the
- table region.
-
- Fixes <https://savannah.gnu.org/bugs/?60140>. Thanks to Hans

- horizontal margins otherwise assumed by this macro file. This
- means that "groff -mm" and "groff -dpaper=letter -mm" are _not_
- synonymous (when groff is configured to use U.S. letter as the

-2022-11-11 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-ext.tmac (UR, MT): Fix problem with incorrect line
- lengths and occasional "can't adjust" warnings when using
- hyperlinks. Reduce the line length within the diversion by the
- amount of indentation used in the context. Without this, lines
- were getting set too short. (You might think they'd be too
- long, but when creating a new environment, the _formatter's_
- default line length is used; that's 65n on terminal devices.)
-
-2022-11-11 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man]: Add test to ensure that link text (when the hyperlink
- itself is not formatted because the device supports
- hyperlinking) uses the correct line length and is adjusted.
-
- * tmac/tests/an_adjust-link-text-correctly.sh: Do it.
- * tmac/tmac.am (tmac_TESTS): Run tests.
-
-2022-11-11 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/devpdf.am: Refactor.
- (MOSTLYCLEANFILES): Populate macro incrementally, adjacent to
- the targets that build the files to be cleaned. This will
- enable cleaner refactoring in the future.
- (DEFAULT_BASE35_FONTS): Add new macro storing the targets of the
- PostScript Level 2 standard base 35 font descriptions.
- (devpdffont_DATA): Populate using `DEFAULT_BASE35_FONTS`.
- (URW_BASE35_FONTS): Add new macro, empty if [!HAVE_URW_FONTS];
- and [HAVE_URW_FONTS] otherwise naming the `U` foundry font
- description counterparts of the `DEFAULT_BASE35_FONTS`.
- (devpdffont_DATA): Append `URW_BASE35_FONTS`.
- ($(DEFAULT_BASE35_FONTS) $(URW_BASE35_FONTS)): Assert dependency
- on "font/devpdf/download". This isn't literally true, but
- BuildFoundries generates all of these together, so if the
- "font/devpdf/download" target rule runs successfully, the font
- description files named in these macro expansions will be
- generated too.
-
-2022-11-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/afmtodit/afmtodit.pl: Add new command-line option to
- specify the generated font description's "spacewidth" parameter;
- in commit bf7f6862c3, 2021-09-24, I made libgroff complain if
- this directive is missing (since any font, even a "special" one,
- can be selected as current and the formatter's behavior when
- encountering an input space should be well-defined under that
- circumstance). Adding this option enables a well-formed font
- description to be produced.
- * src/utils/afmtodit/afmtodit.pl (usage):

-
- * src/utils/afmtodit/afmtodit.pl: Use our own fatal exit

-
-2022-11-09 G. Branden Robinson <g.branden.robinson@gmail.com>

-
-2022-11-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/util/BuildFoundries.pl (LoadFoundry): Stop
- capitalizing beginning of diagnostic message (per GNU Coding
- Standards). Drop ellipsis from end since no further diagnostics
- relevant to that message are expected. Trim trailing slashes
- from font path elements.
-
-2022-11-08 G. Branden Robinson <g.branden.robinson@gmail.com>

-
- * src/preproc/pic/pic.ypp: Slightly refactor. Rename parameter
- `form` (format) to `fmt` to make its nature as an abbreviation
- clear.
- (format_number, do_sprintf): Reorder null pointer equality
- comparisons to avoid inadvertent lvalue assignment.
- (do_sprintf): Declare lists of valid format conversion
- specifiers and modifiers explicitly instead of as happenstance
- literals. Recast diagnostic messages to refer to "invalid", not
- "bad" input; refer to input keyword correctly as "sprintf" (not
- "snprintf"); and report the identity of the invalid conversion
- specifier we reject.

- (doc-print-prefixes, Ar, Nm, Pa, Xr, doc-do-func, Fn)
- (doc-do-func-args, Fo): Remove now-relic resets of type size to

- macro ever changes the type size.
-

-
- [gropdf]: Cater for invalid entries in download file.
-
- * src/devices/gropdf/gropdf.pl: Test if path in the "download"

-
- [mdoc]: Set page topic in roman in "Name" section.
-
- * tmac/doc.tmac (Nm): If in the "Name" section of the page, set
- argument(s) with the `No` (normal formatting) macro instead of
- handling them...normally. Since `Nm`'s usual behavior is to set
- the next argument in boldface, in this circumstance it is set in
- roman. Aligns page rendering with man(7) and fixes a bug
- documented in the 4.3BSD-Reno mdoc.samples(7) page (1990-06-22),
- upon which the groff_mdoc(7) page is based.
- * tmac/groff_mdoc.7.man (Bugs): De-document bug.

- Fixes part of <https://savannah.gnu.org/bugs/?62926>.
-
-2022-11-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/mdoc/doc-common: Add internal register
- `doc-in-name-section` to keep track of whether a macro is called
- within the "Name" section of the document, to prepare a means of
- fixing a long-standing bug with `Nm`.
- (Sh): Canonicalize capitalization of section heading sooner.
- Set or clear `doc-in-name-section` based on result.
- (Rd): Add new register to dump.
- * tmac/doc.tmac (doc-save-global-vars, doc-restore-global-vars):

-
- [mdoc]: Use font CR, not CB, for `Cm` ("command modifier") and
- `Fl` ("flag") macros on typesetters.
-
- * tmac/mdoc/doc-ditroff (doc-Cm-font, doc-Fl-Font): Switch to
- Courier roman from Courier bold. This congrues better with
- other `Li` literals, which were not in boldface.
-
-2022-11-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/mdoc/doc-nroff (doc-Li-Font): Switch from roman to bold.
- On typesetters, the use of Courier (roman) plainly distinguishes
- unquoted literals from their context. On terminals there was no
- such visible distinction. Fortunately, in groff_mdoc(7) itself,
- this does not result in a blinding blitz of boldface because the
- `Ql` (quoted literal) macro is so often used, and it maintains
- the roman style. This change further aligns groff mdoc(7) with
- groff man(7) style conventions. (Also see how we handle
- literals for typesetters and terminals in the "ms.ms" document.)
-
-2022-11-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [mdoc]: Make `Sx` macro perform quotation, not italicization.
- It's thorougly inconsistent with English composition practices

-
-2022-11-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/mdoc/doc-common (doc-header, doc-footer): Revise for
- clarity and to use correct typefaces for titles.
- (doc-header): Add new strings to ease title construction.
- `doc-xref` stores the fully formatted page topic and section
- number, e.g., "troff(1)"; `doc-abbv` stores the its potentially
- abbreviated form when it is too long to fit.
- (doc-footer): Use `doc-xref` as above. Stop setting the `Os`
- and `Dd` parameters in the ("semantic"?) font used for the
- page's section number (probably unnoticed all these years
- because the font used to render that was (Times) roman).

- [eqn]: Fix Savannah #63299.
-
- * src/preproc/eqn/main.cpp: Revise input file line number
- handling.
- (read_line): Stop dealing with `current_lineno` here; it's now
- up to its caller (`do_file()`) to manipulate the line number.
- (do_file): When reading new file, initialize `current_lineno` to
- 1 instead of 0. Reset it to zero when encountering EOF (so that
- diagnostics will not include a line number at all). When
- performing nested call to `read_line()` to gather '.EN' from
- input, increment the line number. Write correct line number in
- output groff `lf` requests; in groff, its first argument assigns
- the number of the _next_ input line. Increment line number at
- end of outer `read_line()` loop.

- ease migration from other documentation formats; in many cases
- there are more idiomatic *roff ways of getting results that

- Unicode defines spaces and dashes of various discrete widths;
- when typesetting with *roff, you can have a space or dash (among

- groff for the 'dvi' output device when using EC fonts. Instead
- remap the T and H family typefaces in all four styles

- add remappings of groff+PostScriptish font names "CB" and "CBI"
- to CW EC faces of normal weight, corresponding to dvi.tmac; see

- [troff]: Describe an input delete character comprehensibly.
-
- * src/roff/troff/input.cpp (token::description): The delete
- character (ISO 127 decimal, EBCDIC 7) is a valid `TOKEN_CHAR`
- but is not printable. Don't attempt to output it literally in
- diagnostics; describe it in a phrase instead.
-
-2022-10-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Apply consistent terminology.
-
- * src/roff/troff/input.cpp: Rename functions to better align
- with our documentation, and decouple their names from an
- assumption of diagnostic severity. Also give them imperative
- names since they are called for their side effects, not their
- return values.
- - empty_name_warning -> diagnose_missing_identifier
- - non_empty_name_warning -> diagnose_invalid_identifier
- (diagnose_missing_identifier): Refer to absent operand as
- "identifier", not "name", in diagnostic messages since the
- latter (strictly) refers to the request/macro/string/diversion
- name space, and this function is also used to gather register
- identifiers.

- * src/roff/troff/input.cpp: Refactor to parallelize logic in
- similar routines; namely, those handling escape sequences that
- accept newlines as argument delimiters.
-
-2022-10-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp: Fix inconsistencies in handling of
- escape sequences that accept newlines as delimiters. Some threw
- spurious warnings as in Savannah #63011; others failed to treat
- a newline-terminated escape sequence also as the ending of an
- input line.
- (do_name_test, do_zero_width): Suppress spurious warning.
- (do_zero_width, do_width, do_special): Synthesize newline to
- terminate input line.
-
-2022-10-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/tests/\
- some_escapes_accept_newline_delimiters.sh: Add test cases for
- `\A` and test formatted output of escape sequences, not just the
- absence of diagnostics from permitted use of newlines as
- argument delimiters.
-
-2022-09-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libdriver/input.cpp (do_file): Make use of
- positioning commands before the first page is started fatal
- errors; they suggest ill-formed input. The 'p' command
- clobbers the vertical position anyway. (See
- https://bugs.debian.org/421437 for discussion.)
-
-2022-09-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/pdf.tmac: Add inclusion guard; if a `pdfmark` macro is
- already defined, skip inclusion of this file. Unfortunately
- there are multiple name collisions with pdfmark.tmac.

-
- * src/roff/troff/input.cpp:
- * src/roff/troff/request.h: Trivially refactor. Boolify
- `interpolate_macro` and `request::invoke`. Also rename
- parameter `no_next` to `do_not_want_next_token`, exposing
- potentially confusing interface design.
-
-2022-09-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (spring_trap, interpolate_string)
- (interpolate_string_with_args): Improve error diagnostics: when
- a sprung trap or an interpolation fails because it's being
- attempted on a request, say so explicitly and _name_ it. If the
- argument to the trap-planting request or to a string
- interpolation escape sequence is itself an interpolation, this
- name might not be obvious. Consider:
- .wh \n[pos] \*[mac]
- .em \*[mac]
- .itc 1 \*[mac]
- \*[\*[mac]]
- Supplying this information requires no additional overhead.
-
-2022-09-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (interpolate_string): Trivially
- refactor. Rename function parameter from `s` to `nm` to more
- obviously align with `interpolate_string_with_args()`.
-
-2022-09-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (do_zero_width, token::description)
- (interpolate_string, interpolate_string_with_args)
- (token::get_char): Revise diagnostic messages to stop presuming
- the identity of the escape character.
-
-2022-09-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (set_escape_char): Recast error
- message to describe attempted operation and tell the user what
- we're doing about being instructed to use an invalid escape
- character.
-
-2022-09-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (read_size): Be more helpful to
- ambiguous type size escape sequence users; offer advice in
- terms of the current escape character.
-
-2022-09-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp (main): Fix SEGV when exiting
- gxditview. The `postdriver` pointer always referred to
- allocated memory except when the `-X` option was given; it was
- then assigned the address of a #defined string literal. It was
- thus statically allocated and an error to attempt to `free()`
- it. Duplicate the string on the heap instead so that we can
- clean up uniformly regardless of postprocessor. Problem caused
- by me when introducing `xexit()` in commit 6769e56aab, 20 June.

-
- * tmac/e.tmac (@o, n2, sk (f, ++): Consistently call `@err`
- macro with `do`.
-
-2022-09-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/e.tmac: Initialize new register `_f`, the value of `$m`
- {column count} of the previous pending footnote, to zero,
- meaning there is no previous pending footnote.
- (@o): Emit diagnostic when flushing footnotes into a different
- column layout than the pending footnote last added. Set `_f` to
- zero.
- ((f): Emit diagnostic when enqueueing footnote using a different
- column layout than the previous pending footnote used. Set `_f`
- to `$m`.

- register `?f`.
-
-2022-09-08 Nikita Ivanov <nikita.vyach.ivanov@gmail.com>
-
- * tmac/ps.tmac: Fallback definitions for glyphs that usually
- come from special fonts should use `schar` instead of `fchar`.
- {Define fallback special characters using `schar` instead of
- `fchar` for glyphs that we do not expect to find in text fonts;
- that is, they don't have bold, italic, and bold-italic stylistic
- variants. This means all special character definitions in the
- file except for rules, ligatures, and digraphs. Problem dates
- back to a series of commits from March 2002 to February 2003,
- straddling the introduction of the `schar` request in November
- 2002. --GBR}

-2022-09-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [ms]: Slightly simplify new `XN` macro feature to align it more
- closely with Berkeley TOC macro behavior; don't prepend the
- table of contents entry with the section number (`\*[SN]`). If
- desired, a document can define `XN-REPLACEMENT`. This does not
- regress "pdfmark.ms" because it uses an alternative, older
- implementation of these features from "spdf.tmac".
-
- * tmac/s.tmac (XH-UPDATE-TOC): Update comments.
- (XN-REPLACEMENT): Do it.
-
-2022-09-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/pdf.tmac (pdf*href-I): Call `pdf:error` macro by its
- correct name. Both this macro file and
- contrib/pdfmark/pdfmark.tmac seem to want to use the 'pdf'
- prefix for their macro names, with much confusing overlap.
- Problem dates back to commit 87046b2948, 2011-07-26.
-
-2022-09-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_URW_FONTS_CHECK): If Ghostscript or awk are
- unavailable, skip only the prepopulation of the URW font search
- path instead of the entire check. This way we still locate the
- URW fonts if they are in one of several standard locations.

- [grodvi, ...]: Trivially refactor.
-
- Tidy up #includes of the "assert.h" header, which we locally

-
- [troff]: Tweak diagnostic messages.
-
- * src/roff/troff/input.cpp (non_empty_name_warning): Say

-
- * tmac/mdoc/doc-ditroff:

-
- [mdoc]: Fix code style nit. Rename `doc-arg-limit` to
- `doc-arg-count`. This register doesn't track any sort of limit
- on the number of arguments you can give to an mdoc(7) macro, or
- anything like that. It is simply a count of the number of

-
- [docs]: Fix errors in documentation regarding which escape
- sequences accept newlines as argument delimiters, and other
- inaccuracies.
-
- * doc/groff.texi (Escape Sequences): Cover general cases before
- exceptional ones. Leaders can be used as argument delimiters.
- Call out letters and numerals as (usually) usable as well.
- Correct an almost completely inaccurate list of escape sequences
- that accept a newline as an argument delimiter: \A, \b, \o, \w,
- \X, and \Z do; \B does not. Correct example of use of newline
- as delimiter with \o escape sequence. Stop referring to the
- decimal point as an "operator". Drop "newline" from a list of
- prohibited delimiters by several escape sequences since it has
- already been discussed.
-
- * man/groff.7.man (Escape sequences): Replace weaksauce cross
- reference to our Texinfo manual with a proper discussion of
- acceptable delimiters in escape sequences, synced with the
- foregoing change. Stop using quotation marks around escape
- sequences, except for "\ " which obviously needs it.

-
- * src/devices/grops/ps.cpp (ps_printer::special)
- (resource_manager::process_file): Fix code style nit. Mark
- static structs initialized within functions and never modified

- false positive from AddressSanitizer. If it doesn't pacify
- ASAN, please explain to me how constant structure members
- initialized to string literals and pointers to functions within

-
- [mdoc]: Align inter-paragraph spacing with man(7).
-
- * tmac/mdoc/doc-common: Use `doc-paragraph-space` when spacing

-
- * tmac/mdoc/doc-nroff: Map monospaced fonts (CR, CB, CI, CBI) to
- standard styles as man(7) has done for 15 years. This silences
- warnings from the formatter when a man page attempts to use
- fonts from the Courier family in tbl(1) tables, which is about

-
- [mdoc]: Stop prefixing center header with name of operating
- system. This was hard-coded to "BSD" and stuck on all mdoc(7)
- pages using a default manual section number, regardless of host
- operating system. Bad idea. Further, the argument to the `Os`
- call, if any, or a default, is always disclosed in the left
- footer.
-
- * tmac/mdoc/doc-common: Do it.
- (Dt): Initialize `doc-volume` as empty and annotate it;
- calling the macro with a numeric second argument overrides the
- fallback default of "LOCAL". A slash is no longer needed to
- separate a recognized architecture string from the OS name, so
- drop it.

-
- * tmac/mdoc/doc-common: Call new macro (see below)
- `doc-set-up-continuous-rendering` when initializing, if that
- mode is configured.
- (doc-ne): New macro replaces `ne` request
- in continuous rendering mode. It extends the page length by the
- amount in the argument or by 1v if none given.
- (doc-bp): New macro replaces `bp` request in continuous
- rendering mode, setting the page length to the vertical drawing
- position.
- (doc-set-up-continuous-rendering): New macro renames requests to
- emplace the foregoing.
- (Dd): Interpret this macro call strictly as starting a new
- mdoc(7) document. (andoc.tmac already makes this assumption,
- and has for over 20 years. groff_mdoc(7) and mandoc_mdoc(7)
- also prescribe the sequence `Dd`, `Dt`, `Os`.) We require this
- invariant even more rigidly now because it's the only way we can
- be sure that we can process multiple documents while rendering
- headers and footers with information corresponding to the
- appropriate document. (man(7)'s `TH` has an advantage here in
- that calling it is "atomic": from its arguments alone you can
- obtain everything you need to know to format the header and
- footer. In mdoc(7), permuting the initialization macro order
- reliably produces chaos.) Break the page (if necessary)
- _before_ processing any arguments (instead of after), to flush
- the previous page's footer. Stop calling `doc-set-up-titles`
- here; we don't have enough information to do that yet. Also
- stop writing the PDF bookmark here, because `doc-document-title`
- and `doc-section` will not reflect the new page content yet.
- (Os): Once the `doc-operating-system` string content has been
- determined, call `doc-set-up-titles`, write the PDF bookmark for
- the page, and call `doc-header`, causing the page header to be
- formatted. These changes further imply a stronger requirement
- on initialization macro ordering being canonical.

- Bug #62934 - after glyph remapped mark it as used
-
- When many glyphs are remapped from code points above 255
- such as writing documents in cyrillic with the U-TR fonts,
- gropdf starts reusing code points in the range 128-255.
- If subsequently one of those code points is actually required,
- such as \(em (code 138), and it has been replaced by a
- cyrillic, then it needs to be mapped to another free code.
-
- To determine if a particular code point is free each glyph
- has a USED flag. The bug was caused because after remapping
- \(em to the next free glyph the USED flag was not set. So the
- next new cyrillic character to be entered was given the same
- code point as had been allocated to \(em.
-
- * src/devices/gropdf/gropdf.pl: Set the USED flag on remapped

- * tmac/an.tmac (TS): Stop inserting space before tables. Unlike

- And not up to us to impose it.

-
- * m4/groff.m4 (GROFF_PAGE): Use 'grep -q' instead of redirecting
- standard output to null device. The '-q' option was
- standardized in POSIX Issue 5 (1997) or earlier. Also drop the
- redirection of the standard error stream; we have already
- checked the file named in "$descfile" for existence and
- readability. grep should thus not emit diagnostic messages.
-
-2022-07-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PAGE): Macro used awk(1) without
- `AC_REQUIRE`-ing a relevant macro or checking for its existence.
- Fortunately, sed is powerful enough for our needs. Remove
- dependency on awk. Cope with "search" directive in resolv.conf
- having multiple arguments. Match "domain" directive in same
- file instead of "dom", which I cannot find attested (this logic
- dates to 1991). Rename `dom` shell variable to `domains` for
- clarity, since its multiplicity could be greater than 1.
-
-2022-07-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PAGE): Refactor: drop AC_DEFINE of
- `PAGEA4`. This symbol appears to be a relic; it is nowhere
- tested or dereferenced.
-
-2022-07-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/tty-char.tmac: Drop definition of \[sd] special

-
- * font/devpdf/devpdf.am: Refactor to simplify. Now that

-
- * font/devpdf/util/BuildFoundries.pl (LoadFoundry): Recast

- of failure to locate a Type 1 font file (that isn't one of the
- base 14 PostScript level 1 fonts): the font will be unavailable
- for the "pdf" output device.
-
-2022-07-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/util/BuildFoundries.pl (LoadFoundry): Separate

-
- [afmtodit]: Clarify diagnostic message.
-
- * src/utils/afmtodit/afmtodit.pl: When we have excess Adobe
- Glyph List mappings for a groff special character identifier
- {making the reverse mapping from groff special character to font
- glyph name ambiguous}, report that we're ignoring the excess.
- Use "print STDERR" instead of Perl "warn" built-in since we want
- diagnostic messages to start with the name of the program
- emitting them.
-
-2022-07-10 G. Branden Robinson <g.branden.robinson@gmail.com>

- aid debugging.
-
-2022-07-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/node.cpp (get_register, get_string): Reorder
- null pointer inequality comparisons; they don't need to be in a
- funny order because it's pretty hard to mistype `!=` as an
- assignment operator. Annotate them as null pointers to ease any
- future migration to ISO C++11. Use primitive type constructor
- instead of C-style cast operator; this seems more idiomatic.
-
-2022-07-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/html/pre-html.cpp (generateImages): Flush the
- standard error stream after writing to it in a loop.
-
-2022-07-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/s.tmac (RP): Recognize new optional arguments
- `no-renumber` and `no-repeat-info`, the latter as a synonym for
- the existing `no`. The former suppresses the page number
- manipulation that normally occurs. Drop now-unnecessary `pn 0`
- request.
- (top level, cov*first-page-init, RP, cov*print): Rename
- `cov*rp-format` to `cov*use-rp-format` for clarity.
- (cov*break-page): New macro breaks the cover page at the end,
- resetting next page number to 1 only if desired by user.
- (cov*print, cov*rp-print): Call `cov*break-page` instead of
- invoking `bp`.

-
-2022-07-08 Deri James <deri@chuzzlewit.myzen.co.uk>
-
- * font/devpdf/util/BuildFoundries.pl (LocateFile): Some systems
- store .afm files in a parallel directory to the Type 1 files,
- restore original path after checking for parallel directory.
-
-2022-07-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/devpdf.am (font/devpdf/download): Call

-
-2022-07-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/util/BuildFoundries.pl: Add Boolean-valued scalar

-
- * tmac/s.tmac (UX): Drop undocumented support for this macro.

- was an imposition by the AT&T legal department on the CSRC.

-
- * src/roff/groff/pipeline.c: Refactor. Drop function rename via

- (run_pipeline): Update call sites. Stop flushing standard error
- stream after calling libgroff's `error` function (which

-
-2022-07-01 G. Branden Robinson <g.branden.robinson@gmail.com>

-
-2022-06-27 G. Branden Robinson <g.branden.robinson@gmail.com>

-
-2022-06-27 G. Branden Robinson <g.branden.robinson@gmail.com>

-
-2022-06-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/html/pre-html.cpp: Refactor. Drop unnecessary
- prototype for static function. Use idiomatic C++98 null pointer
- constant. Annotate it as null pointer to ease any future
- migration to ISO C++11. Boolify. Use C++98 bool data type
- instead of preprocessor macros `TRUE` and `FALSE`. Demote some
- global Boolean variables from `int` to `bool` and rename some to
- be more clear: `show_progress` -> `want_progress_report`;
- `debugging`; `eqn_flag` -> `need_eqn`.
- (make_message): Rename this...
- (make_string): ...to this. Align more closely with contemporary
- version of example from Linux man-pages printf(3) page. Use
- `vsnprintf()` to determine size of memory buffer needed prior to
- allocation instead of iteratively growing it until it is large
- enough. Always die if `vsnprintf()` fails: this function now
- always returns a valid pointer if it returns at all.
- (makeFileName, setupAntiAlias, imageList::createPage,
- imageList::createImage): Update call sites to use
- `make_string()`.
- (char_buffer::can_see): Demote return type from `int` to `bool`.
- (char_buffer::skip_spaces): Drop unused member function.
- (char_buffer::read_file, makeTempFiles): Demote return type from
- `int` to `void`. Stop returning after calling functions that
- don't return.
- (char_buffer::read_file): Call `sys_fatal()` if `fread()`
- returns an error, similarly to other calls into the standard C
- library that this file makes. Improve check for error from
- `fread()` by not regarding a return value of zero when the
- end-of-file indicator is set as an error condition.
- (makeFileName, checkImageDir, char_buffer::run_output_filter,
- scanArguments): Call `fatal()` instead of `error()` and then
- `exit(1)`.
- (makeFileName, scanArguments): Dismiss Shlemiel the Painter:
- save return value of `strlen()` and call `strcpy()` multiple
- times instead of mixing `strcpy()` and `strcat()`; the latter
- approach rescans the string unnecessarily.
- (char_buffer::run_output_filter): Stop passing unnecessary null
- pointer argument to diagnostic message functions. Stop calling
- `fflush()` after libgroff diagnostic function, which always
- {ultimately} flushes the standard error stream itself.
- (makeTempFiles, do_file, main): Boolify.
- (makeTempFiles, do_file): Reorder null pointer equality
- comparisons to avoid inadvertent lvalue assignment.
- (scanArguments, main): Use `EXIT_SUCCESS` and `EXIT_FAILURE`
- constants from C library instead of integer literals for exit
- status.
- (do_file): Demote return type from `int` to `bool`. Return
- Boolean literals. Drop conditional with empty consequent.
- (main): Declare local variables closer to the points of use.
- Stop trying to be a register allocator: stop reusing loop index
- variable `i` as integer storage for another (albeit related)
- purpose; introduce `operand_index` instead. Clarify logic by
- splitting combined initialization and comparison operations, and
- by testing function return value directly instead of storing it
- in a pointless temporary. Use `EXIT_SUCCESS` and `EXIT_FAILURE`
- constants from C library instead of integer literals for exit
- status.

- (main): Issue fatal diagnostic if child process exited with
- nonzero status. Since the child's output to the standard error
- stream is lost, advise re-running with different output driver
- to see them. This unhappy shortcoming is filed as Savannah
- #62673. Explicitly return zero otherwise.

-
- * src/roff/groff/tests/ab_works.sh: Add regression test for
- Savannah #60782.
-
-2022-06-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Trivially refactor.
-
- * src/roff/troff/input.cpp (token::next): Rename statement label
- to use documentary terminology.
- * src/roff/troff/node.cpp (make_composite_node)
- (make_glyph_node): Make functions static since nothing outside
- this translation unit calls them.
- * src/roff/troff/node.cpp (make_glyph_node): Refactor optional
- argument and its usage. Put it down, flip it, and reverse it.
- That is, demote its type from `int` to `bool`, invert its sense,
- and rename it since it affects warning, not error, diagnostics.
- (character_exists): Update only call site of `make_glyph_node()`
- that uses non-default argument value.
-
-2022-06-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Adjust diagnostic message text to clarify and better
- match terminology used in documentation.
-
- * src/roff/troff/input.cpp (set_escape_char, do_overstrike)
- (do_bracket, do_name_test, do_width, do_special):
- * src/roff/troff/node.cpp (suppress_node::tprint): Migrate from
- "escape" to "escape sequence".
-
- * src/roff/troff/node.cpp (make_composite_node)
- (make_glyph_node): Clarify what went wrong.
-
- * src/roff/troff/input.cpp (token::get_char)
- (check_missing_character): Migrate from "normal character" to
- "ordinary character" (see groff_char(7)).
-
-2022-06-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Rename a function for clarity.
-
- * src/roff/troff/input.cpp (add_to_node_list): Rename this...
- (add_to_zero_width_node_list): ...to this.
- (do_zero_width): Update call site.
- * src/roff/troff/token.h: Update declaration.
-
-2022-06-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp (handle_unknown_desc_command):
- Refactor to skip unnecessary string comparisons. We explicitly
- return in the final case instead of falling off the end of this
- void function for consistency if additional cases are added.
-
-2022-06-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp (handle_unknown_desc_command):
- Partially revert commit 64dc40d23a, 19 June. I forgot to save
- and restore the previous values of the globals
- `current_filename` and `current_lineno`, and, noticing that this
- function has 3 return paths, decided that it's cheaper just to
- go back to `error_with_file_and_line()`.
-
-2022-06-21 Deri James <deri@chuzzlewit.myzen.co.uk>
-
- [gropdf]: Add more search paths to the Foundry file.
-
- * font/devpdf/Foundry.in: Use the directory specified with the
- config flag --with-urw-fonts-dir to populate the default foundry
- as well as the U foundry. Important to populate the download
- file with font files to embed the fonts not part of the base
- pdf fonts or if user wants all fonts embedded.
-
-2022-06-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-ext.tmac (UR, MT): Fix problem with hyphenation
- occurring before the end of the line when the line length was
- not the device default (common for man pages at the terminal)
- and hyperlinks were enabled. The issue is that the new
- environment we created inherits the default environment's line
- length (its state at troff initialization, prior to macro
- package loading and configuration). This latent issue was
- exposed by post-groff 1.22.4 changes to enable the hyphenation
- of link text and add the hyperlink feature. Fix it by copying
- the line length at the time the macro is called, which is
- necessarily after man(7) sets up the line length, to the new
- environment.
-
-2022-06-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/grops/psrm.cpp (resource_manager::output_prolog):
- (resource_manager::supply_resource):
- (resource_manager::read_download_file): Update diagnostic
- message language and report underlying problem encountered by
- system when failing to open files. This will probably be the
- text for ENOENT in most cases, but should help avoid frustration
- in those where it isn't.
-
-2022-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/grops/psrm.cpp
- (resource_manager::read_download_file): Align diagnostic message
- wording with gropdf in the same circumstance.
-
-2022-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Throw warning in font category when a font selection
- escape sequence is used after the output line continuation
- escape sequence on an input line, because it is ignored.
-
- * src/roff/troff/env.cpp (environment::set_font): Do it.
-
- * doc/groff.texi (Warnings):
- * src/roff/troff/troff.1.man (Warnings): Document it.
-
-2022-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/env.cpp (font_change): Boolify.
-
-2022-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/gropdf/gropdf.pl (LoadFont): Revise error message
- when a font can't be found for embedding. User failure to add
- an entry for locating the font file seems a more likely scenario
- than outright corruption of the file.
-
-2022-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/env.cpp (font_change): Warn upon selection of a
- nonexistent font name.
-
- Fixes <https://savannah.gnu.org/bugs/?62656>.
-
-2022-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Revise `environment::set_font` to return Boolean value
- indicating success of font selection operation.
-
- * src/roff/troff/env.cpp (environment::set_font):
- * src/roff/troff/env.h (environment::set_font): Do it.
-
- This prepares the way for a fix for Savannah #62656.
-
-2022-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp: Use single exit path, freeing
- memory allocated for strings.
- (xexit): Add `exit()` wrapper; free allocated memory.
- (main): Use it in all three exit paths.
-
-2022-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp: Refactor to be more meticulous with
- memory. Add globals `saved_path`, `groff_bin_path`, and
- `groff_font` to store pointers into the process environment
- returned by `putenv()`; once used, they need to remain valid for
- the lifetime of the program.
- (xstrdup): Add `strdup()` wrapper: dies if `strdup()` fails.
- (main): Split nested `strsave()` and `xputenv()` (until recently
- `putenv()`) calls. Free duplicate strings prior to exit.
-
-2022-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp (main): Rename temporary variable to
- avoid shadowing one in enclosing scope, which can lead to
- cut-and-paste errors (ask me how I know).
-
-2022-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp: Slightly refactor to indirect
- `putenv` calls through an error-checking wrapper.
- (xputenv): Add new function to die if `putenv()` fails.
- (main): Update call sites to use it.
-
-2022-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [groff]: Add information to diagnostic messages.
-
- * src/roff/groff/groff.cpp (main): Report underlying system
- error if `putenv()` fails.
- (handle_unknown_desc_command): Set globals `current_filename`
- and `current_lineno` from `filename` and `lineno` arguments
- passed to us to we can use the simpler interface of `error()`
- rather than `error_with_file_and_line()`.
-
-2022-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Update return type of `font::load_desc` function to
- enable more informative diagnostics from callers.
-
- * src/include/font.h (font::load_desc): Change return type from
- `bool` to `const char` pointer.
- * src/libs/libgroff/font.cpp (font::load_desc): Return null
- pointer literal on failed `open()` or validation failures.
- Return filespec on success.
-
- * src/libs/libdriver/input.cpp (do_file):
- * src/preproc/grn/main.cpp (getres):
- * src/roff/groff/groff.cpp (main):
- * src/roff/troff/input.cpp (main): Compare `font::load_desc()`
- return value to null pointer literal instead of treating it as a
- Boolean.
-
- * src/roff/groff/groff.cpp (main): Report full filespec of
- troublesome "DESC" file when complaining of missing "postpro"
- directive.
-
-2022-06-18 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp: Add new Boolean global,
- `need_postdriver`, and initialize it true.
- (main): Make `need_postdriver` false if the `-X` or `-Z` options
- are given. Test it later. This prevents groff from exiting
- with a fatal error if an output driver is not available, but
- also not required. Also reorder null pointer equality
- comparison to avoid inadvertent lvalue assignment.
-
- Fixes <https://savannah.gnu.org/bugs/?62640>.
-
-2022-06-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp (help): Revise usage message for
- expressiveness and clarity.
-
-2022-06-21 Deri James <deri@chuzzlewit.myzen.co.uk>
-
- [gropdf]: Correct display of pathnames used.
-
- * font/devpdf/util/BuildFoundries.pl: Convert array to
- string of pathnames.
-
-2022-06-21 Deri James <deri@chuzzlewit.myzen.co.uk>
-
- [gropdf]: Fix to gropdf.
-
- * src/devices/gropdf/gropdf.pl: If pdfbookmark was called
- within 5p of top of page (e.g. straight after a .bp when
- \n[nl] was zero) the click destination would be off by a
- page.
-
-2022-06-19 Ingo Schwarze <schwarze@openbsd.org>
-
- * font/devpdf/devpdf.am: Always build PDF font description
- files.
-
- Build font/devpdf/download and the various TR, TB, CR etc.
- files in the same directory even when they are not required
- by the build because USE_GROPDF is unset, usually because
- ghostscript is either unavailable or deliberately disabled
- by the person running the build. These files need to be
- built and installed anyway, and can be used on the target
- system when the required infrastructure is available at run
- time.
-
-2022-06-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [docs]: Revise introduction of vertical spacing concept to avoid
- render inference that the formatter will compute a vertical
- spacing appropriate to the type size automagically--it will not.
-
- Fixes <https://savannah.gnu.org/bugs/?62617>. Thanks to Dave
- Kemper for the report.
-
-2022-06-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [docs]: Revise discussion of end-of-sentence detection.
-
- * doc/groff.texi (Filling):
- * man/roff.7.man (Concepts): Do it. "Spaces" is a now a term
- with a much more restricted usage. Emphasize the input context,
- now explicitly identified as plain text files with Unix line
- endings.
-
- Fixes (one hopes) <https://savannah.gnu.org/bugs/?62593>.
- Thanks to Ingo Schwarze for the report and Dave Kemper for the
- discussion.
-
-2022-06-10 Deri James <deri@chuzzlewit.myzen.co.uk>
-
- [gropdf]: Changes to BuildFoundries.
-
- * font/devpdf/util/BuildFoundries.pl: Collect search paths into
- an array rather than a colon delimited string, this allows
- the @PATH_SEPARATOR@ character (':' or ';') to be used to
- delimit paths yielded by the command 'gs -h' but still use ':'
- to delimit paths in the Foundry file. This means the same
- Foundry file can be used on all systems.
-
- * font/devpdf/Foundry.in: Add more likely paths to find the URW
- fonts.
-
-2022-06-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Weaken dependency on TeX, instead using it (to generate
- the DVI and PDF forms of our Texinfo manual) only if it is
- available.
-
- * m4/groff.m4 (GROFF_USE_TEX_CHECK): Check for presence of 'tex'
- executable in path. Set shell variable `groff_use_tex` to "yes"
- if present, and "no" otherwise. This check runs only if the
- 'makeinfo' and 'texi2dvi' version checks have already passed.
-
- * configure.ac: Run the new check. Set Automake conditional
- `USE_TEX` only if shell variable `groff_use_tex` is "yes".
- Report whether "groff.dvi" and "groff.pdf" are (re-)buildable.
-
- * doc/doc.am: Parameterize names of groff.{dvi,pdf} targets as
- Make macros `GROFF_DVI` and `GROFF_PDF`. Define them only if
- `USE_TEX`. Do _not_ update `EXTRA_DIST` macro; leave the
- literal file names there because we require that distribution
- archives contain these files.
- (.texi.dvi, .texi.pdf): Update suffix rules to check `USE_TEX`
- and fail, complaining of missing 'tex' program, if these targets
- are attempted without it being true. Only manually specifying
- the file names as targets to 'make' or attempting to generate a
- distribution archive without TeX present should cause these
- errors.
-
- * INSTALL.REPO: Update dependency information.
-
- Fixes <https://savannah.gnu.org/bugs/?62592>. Thanks to Deri
- James for the report.
-
-2022-06-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (.texi.dvi, .texi.pdf, $(DOC_GNU_EPS)): Quote names
- of programs when aborting because they're missing.
-
-2022-06-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PROG_MAKEINFO, GROFF_PROG_TEXI2DVI):
- Largely revert commit d5013ededc, 21 May: run checks for
- 'makeinfo' and 'texi2dvi' programs regardless of presence of
- ".tarball-version" file. Their presence is a necessary (but not
- sufficient) condition for refresh of formatted forms of our
- Texinfo manual if the source is modified.
-
- Begins addressing <https://savannah.gnu.org/bugs/?62592>.
-
-2022-06-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Rename some groff Autoconf macros to better match
- Autoconf's own naming conventions.
-
- * m4/groff.m4 (GROFF_MAKEINFO): Rename to...
- (GROFF_PROG_MAKEINFO): ...this.
- (GROFF_TEXI2DVI): Rename to...
- (GROFF_PROG_TEXI2DVI): ...this.
-
- * configure.ac:
- * m4/groff.m4 (GROFF_TEXI2DVI): Update call sites.
-
-2022-06-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an.tmac (SH, SS, B, I, SM, SB): Set input trap with `it`
- instead of `itc` for better Unix Version 7 man(7) compatibility.
-
- Fixes <https://savannah.gnu.org/bugs/?51468>. Also see
- discussion at
- https://lists.gnu.org/archive/html/groff/2022-06/msg00020.html
- et sequentia (amid a vigorous bikeshedding of `\&`'s name).
-
-2022-06-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man]: Regression-test use of input traps.
-
- * tmac/tests/an_use-input-traps-correctly.sh: Do it.
- * tmac/tmac.am (tmac_TESTS): Run test.
-
-2022-06-06 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/gropdf/gropdf.pl (LoadDesc): Validate device
- description file for essential directives and acceptable values
- as grops(1) does.
-
-2022-06-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff, grohtml, grops, grotty]: Update wording of diagnostic
- messages to refer to "motion quantum" rather than "resolution"
- where appropriate.
-
- * src/devices/grohtml/post-html.cpp
- (html_printer::html_printer):
- * src/devices/grops/ps.cpp (ps_printer::ps_printer):
- * src/devices/grotty/tty.cpp (tty_printer::set_char)
- (tty_printer::add_char, tty_printer::end_page):
- * src/roff/troff/env.cpp (line_length, title_length): Do it.
-
-2022-06-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/gropdf/gropdf.pl: Do more "DESC" file validation.
- (LoadDesc): Bomb out gracefully if any of "unitwidth", "res", or
- "sizescale" missing from "DESC" file. This prevents Perl
- warnings about use of uninitialized values, and undoubtedly
- mangled output.
-
-2022-06-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/gropdf/gropdf.pl: Revise diagnostic message
- handling.
- (top level): Add new scalar `progname` to house executable name.
- (Msg): Output messages in format recommended by GNU Coding
- Standards manual. Identify who's talking (Savannah #52463).
- Rename `lev` scalar to `fatal` since it is used only as a
- Boolean for immediately exiting with failure status. Report
- diagnostic severity as part of message.
- (Warn, Die): Add new subroutines through which all diagnostics
- are now emitted.
- (top level): Migrate a use of Perl `die` builtin to our `Die`.
- (top level, ToPoints, LoadDownload, LoadDesc, do_x, GetPoints,
- LoadSWF, LoadPDF, LoadStream, BuildStream, ParsePDFHash,
- LoadFont, GetType1, GetChunk, RemapChr, do_N): Migrate `Msg(0,
- ...)` calls to `Warn` and `Msg(1, ...)` to `Die`. Begin
- messages in lowercase (GNU Coding Standards). Recast a few
- messages for clarity.
-
- Continues the long process of fixing Savannah #52463.
-
-2022-06-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/gropdf/gropdf.pl (Load_Config): Drop unused
- subroutine and its commented-out call site, which came in that
- way in July 2011.
-
-2022-06-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/gropdf/gropdf.pl (LoadFont): Warn if a font to be
- embedded in PDF output cannot be located in the "download" file.
-
- Fixes <https://savannah.gnu.org/bugs/?62572>. Thanks to Deri
- James.
-
-2022-06-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/a4.tmac: Drop file from distribution. It has been
- superseded by papersize.tmac for nearly 20 years.
- * tmac/tmac.am (TMACNORMALFILES): Delete reference.
- * NEWS: Add item.
-
- Fixes <https://savannah.gnu.org/bugs/?62569>.
-
-2022-06-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Parameterize X11-related man pages, so they don't get
- spuriously generated (and not cleaned) when building with X11
- support disabled.
-
- * Makefile.am (.man): Fix logic nit: drop unnecessary removal of
- target before clobbering it with sed.
- * src/devices/xditview/xditview.am (GXDITVIEW_MAN1): Add new
- macro, expanding to nothing if `WITHOUT_X11` and to the target
- name otherwise.
- (man1_MANS): Append `GXDITVIEW_MAN1` expansion, not a literal.
- * src/devices/xditview/xditview.am (XTOTROFF_MAN1): Add new
- macro, expanding to nothing if `WITHOUT_X11` and to the target
- name otherwise.
- (man1_MANS): Append `XTOTROFF_MAN1` expansion, not a literal.
- * doc/doc.am (GROFF_MAN_PAGES1): Append foregoing expansions
- instead of literals.
-
-2022-06-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: Add `AM_CONDITIONAL`: `HAVE_URW_FONTS`, so our
- Automake files can more easily cope with their absence.
- * font/devpdf/Foundry.in: Add easily matched phrases to
- comments, to clearly delimit the URW foundry portion of the file
- so it can be omitted if those fonts are absent.
- * font/devpdf/devpdf.am (font/devpdf/Foundry): Generate file
- differently depending on `HAVE_URW_FONTS`; keep the existing
- procedure if true, and delete the URW section from the generated
- file otherwise, avoiding diagnostic messages from afmtodit(1)
- and our BuildFoundries script.
-
- Fixes <https://savannah.gnu.org/bugs/?62570>.
-
-2022-06-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/devpdf.am (font/devpdf/util/BuildFoundries):
- Generate script using the `PATH_SEPARATOR` Automake macro.
- * font/devpdf/util/BuildFoundries.pl: Add `pathsep` scalar to
- house the build-time path separator.
- (LocateFile): Use it.
- (LoadFoundry, CheckFoundry): Stop using spaces as part of the
- path separation delimiter. It is not idiomatic.
-
-2022-06-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: Explicitly identify poppler tools in report.
-
-2022-06-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/util/BuildFoundries.pl: Trivially refactor. Drop
- unused hash `foundry`. Drop scalar `warn` that was set and
- updated but never tested.
-
-2022-06-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/util/BuildFoundries.pl: Alter script to write to
- the standard output stream instead of (re)writing a file named
- "download" in the current working directory. This recovers from
- a problem I introduced in commit 6e62be835d, 2 May, as an
- unforeseen side effect of improving build parallelism so that
- the "download" file wouldn't be read until it was fully
- populated. As a side benefit, this approach is more Unixy, and
- less dependent on $PWD.
- (top level): Stop calling `WriteDownload` with an argument.
- (LoadFoundry): Close only the file handle of interest when done,
- not all of them (including `STDOUT`, which we now need).
- (CheckFoundry): Same--just for cleanliness, since at present
- running the script in 'check' mode doesn't write to any streams.
- (WriteDownload): Stop taking an argument and manipulating file
- handles. Write download file to standard output.
- (LoadDownload, WriteDownload): Drop `top` scalar, used as a
- mutex to serialize read and write access to "download" file; it
- is no longer needed since the "download" file is now only read.
-
-2022-06-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Rename shell variables and Autoconf/Automake macros of
- Boolean sense to have names more like logical predicates and
- avoid doofy "DONT" nomenclature.
-
- * m4/groff.m4 (GROFF_MAKE_RM): Rename shell variable
- `groff_is_rm_defined` to `groff_make_defines_rm` (purely for
- clarity; it already had a good name).
- (GROFF_MAKE_RM): Rename this...
- (GROFF_MAKE_DEFINES_RM): to this, to make parallelism obvious,
- and enabling...
- * configure.ac: ...rename of `MAKE_DONT_HAVE_RM` to
- `MAKE_DEFINES_RM` with sense of test reversed. Also interpolate
- `GROFF_MAKE_DEFINES_RM` instead of `GROFF_MAKE_RM`. This in
- turn enables...
- * Makefile.am: ...revision of conditional from
- `MAKE_DONT_HAVE_RM` to "!`MAKE_DEFINES_RM`".
-
-2022-06-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_URW_FONTS_PATH)
- (GROFF_WITH_COMPATIBILITY_WRAPPERS, GROFF_APPDEFDIR_OPTION)
- (GROFF_UCHARDET): Recast help strings to more closely parallel
- structure and style of Autoconf's own help strings.
- (GROFF_WITH_COMPATIBILITY_WRAPPERS): Recast to tighten wording.
-
-2022-06-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac:
- * m4/groff.m4 (GROFF_APPDEFDIR_OPTION, GROFF_APPDEFDIR_DEFAULT)
- (GROFF_APPDEFDIR_CHECK): Rename m4 macros and shell variable
- from "*appres*" to "*appdef*. Update interpolation sites.

-2022-06-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_X11, GROFF_UCHARDET): Drop redundant
- messages (which are easily overlooked amid the torrent of
- "checking" output anyway). Discovery failures of X11 and the
- uchardet library are already parts of the configuration report
- at or near the end of output.
-
-2022-06-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PNMTOPS_NOSETPAGE): Partially revert change
- from 21 May and document why in a comment.
-
-2022-06-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/troffrc: Skip loading of "papersize.tmac" if not in troff
- mode.
-
- Fixes <https://savannah.gnu.org/bugs/?62238>. Thanks to Bjarni
- Ingi Gislason for the report.
-
-2022-05-31 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: Report use of "g" prefix for commands and macro
- package compatibility wrappers.
- * m4/groff.m4 (GROFF_G): Fix code style nits. Update
- indentation to match recent practice.
-
-2022-05-31 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: Fix code style nits and tweak report. Stop
- superfluously using braces for shell parameter expansions that
- don't require them. The shell is not make(1). Say
- "installation _directory_ prefix" since another kind of prefix
- can be used by groff (the "g" in front of command and macro
- package names shared with AT&T troff).
-
-2022-05-31 Dave Kemper <saint.snit@gmail.com>
-
- * doc/groff.texi: Fix content and style nits.
- - Remove redundancy ("fixed-width... character that can't be
- adjusted").
- - Fix incorrect word ("environment value" -> "environment
- variable").
- - Add or change the placement of a couple tie{}s to comport
- with style-guide recommendation.
- - Grammarify.
- - Clarify and tighten wording.
-
- Fixes <https://savannah.gnu.org/bugs/?62551>.

-2022-05-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/node.cpp (font_position): If mounting a font
- fails and a third argument was given (to the `fp` request),
- report its value in the diagnostic message. This could reveal a
- prohibited attempt at directory traversal. See commit
- a891161bc9, 7 November.
-
-2022-05-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libgroff/fontfile.cpp (font::open_file): Refactor.
- Move more logic, including memory allocation, inside conditional
- that accepts only file names without '/' characters, skipping
- unnecessary work in the alternative. Annotate use of zero
- literals as null pointers to ease any future migration to ISO
- C++11. Add 'const' qualifier to variable that doesn't require
- modification (and which is used in the LHS of an equality
- comparison, so that clumsy operator misuse will provoke a
- compiler warning).
-
- Fixes <https://savannah.gnu.org/bugs/?62532>. Thanks to Bjarni
- Ingi Gislason for the report.
-
-2022-05-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: In configuration report, say that we're
- reporting compiler options along with the compiler executable.
- Fix leftover test(1) comparison with garbage, overlooked in
- commit faa22d89d2, 20 May.
-
-2022-05-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (doc/meintro_fr.ps): Build with '-t' option.
-
- Fixes <https://savannah.gnu.org/bugs/?62542>. Thanks to Bjarni
- Ingi Gislason for the report.
-
-2022-05-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.1.man (Options) <-l>: Handle case where
- no default print spooler is configured, and report formatter
- behavior correctly if it isn't.
-
- Fixes <https://savannah.gnu.org/bugs/?62535>. Thanks to Bjarni
- Ingi Gislason for the report.
-
-2022-05-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am (.man): Process '@PSPRINT@' substitutions with
- "makevarescape.sed".
-
-2022-05-26 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PROG_YACC, GROFF_MAKEINFO, GROFF_TEXI2DVI):
- Fix logic error in detection of build scenario: the presence of
- a ".git" directory is not an indicator that we're not building
- from a distribution archive, because we might be building from a
- snapshot archive (which also lacks it). Instead, perform checks
- required only by builds from Git checkouts and snapshot archives
- if the ".tarball-version" file is not present.
-
-2022-05-26 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am (EXTRA_DIST): Ship "HACKING" file.
-
-2022-05-26 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * bootstrap.conf: Add "pkg-config" to `buildreq`. Not having it
- causes pretty horrible macro expansion problems and diagnostics
- when 'autoreconf' is run; they're still pretty bad even if you
- use `AC_REQUIRE` and `m4_pattern_forbid`. So just demand it.
-
-2022-05-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devps/S:
- * font/devps/symbolmap: Drop excess mapping of `*U` special
- character. groff maps it to the Adobe Glyph List name
- 'Upsilon1'. (The AGL 'Upsilon' is a homoglyph of the Latin
- capital 'Y'.)
- * PROBLEMS: De-document build-time warning, now resolved.
-
-2022-05-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/afmtodit/afmtodit.tables: Regenerate using Unicode
- 14.0. No substantive changes.
-
-2022-05-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/afmtodit/make-afmtodit-tables: Refactor. Drop
- unused variable `prog`. Use value of `CPP` from environment (if
- defined) and use parameter expansion to apply a default if null
- or not set. Use for loop to eliminate duplicative if statement.
- Test input files for readability, not just existence. Use more
- portable test(1) and shell syntax. Swap usage error and fatal
- error exit statuses; using "1" for failure and "2" for usage
- errors is more common in shell scripts I've seen. Update usage
- message to put non-literal parameter in full caps, and clarify
- its name. Update comment blocks written to generated files to
- further clarify data provenance.
-
-2022-05-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PRINT): Refactor. Stop performing checks
- for spooler options if none is available. Stop redundantly
- reporting command name used for spooling PostScript files. If
- an option is required for spooling DVI files, report it alone
- instead of repeating the command name as well.
-
-2022-05-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Fix insensitivity of groff(1) man page to configured spooler.
-
- * Makefile.am (.man): Replace `@PSPRINT@` in man page sources
- with name of configured print spooler command.
- * src/roff/groff/groff.1.man (Options) <-l>: Use configured
- print spooler command instead of literal 'lpr'.
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_UCHARDET_CHECK): Fix grammar nit in failure
- message when user demands uchardet support but the library
- cannot be located.
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_CHECK_GROHTML_PROGRAMS): Fix logic error in
- computation of verb to be used in notice message.
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PROG_YACC, GROFF_URW_FONTS_CHECK)
- (GROFF_WITH_COMPATIBILITY_WRAPPERS, GROFF_UCHARDET_NOTICE):
- Improve shell code portability. Per the GNU Autoconf manual,
- "The -a, -o, '(', and ')' operands are not present in all
- implementations, and have been marked obsolete by Posix 2008.
- ...portable uses of test should never have more than four
- arguments, and scripts should use shell constructs like '&&' and
- '||' instead."
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.1.man (Installation directories): Don't
- output a tagged paragraph for the X11 application defaults
- directory if the build symbol '@APPRESDIR@' is not defined (that
- is, we didn't build with X11 support).
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_GHOSTSCRIPT_VERSION_CHECK): Fix code style
- nits. Use lowercase for shell variables we define. Don't quote
- literal operands to test(1) that don't contain syntactically
- shell-significant characters. Update indentation to match
- recent practice.
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_URW_FONTS_NOTICE): Don't emit the notice if
- Ghostscript isn't available, since it was a prerequisite for
- the `GROFF_URW_FONTS_CHECK` macro in the first place.
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Add print spooler determination to configuration
- report.
-
- * m4/groff.m4 (GROFF_PRINT): Add shell variable
- `groff_have_spooler` to house the name of the print spooler
- {"lp" or "lpr"} or the word "no".
- * configure.ac: Report determined spooler, or its absence.
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/preconv/tests/do-not-seek-the-unseekable.sh: Skip
- seekability check of the standard input stream if there is no
- controlling terminal.
-
- Fixes <https://savannah.gnu.org/bugs/?62506>. Thanks to Bjarni
- Ingi Gislason for the report.
-
-2022-05-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_CHECK_GROHTML_PROGRAMS): Migrate from
- `AC_FOREACH` to `m4_foreach` to avoid obsolescence warning from
- GNU Autoconf 2.70 or later.
-
- Fixes <https://savannah.gnu.org/bugs/?61059>. Thanks to Bjarni
- Ingi Gislason for the report.
-
-2022-05-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * man/groff.7.man: Rename "pilot" list macros for man(7) from
- `BL`/`EL` to `LS`/`LE`, per suggestion from Alejandro Colomar.
-
-2022-05-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_MAKEINFO, GROFF_TEXI2DVI): Check for
- makeinfo(1) and texi2dvi(1) programs only if building from Git,
- not a distribution archive.
-
-2022-05-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (doc/meintro_fr.ps): Call groff with `-K utf8`
- instead of `-k`, in case the "configure" script didn't find
- uchardet (and preconv(1) thus can't auto-detect an encoding).
-
- Fixes <https://savannah.gnu.org/bugs/?59463>.
-
-2022-05-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/preconv/tests/do-not-seek-the-unseekable.sh: Skip
- a check if /dev/stdin is not a character special device.
-
-2022-05-21 G. Branden Robinson <g.branden.robinson@gmail.com>

-
- * m4/groff.m4 (GROFF_UCHARDET_NOTICE): Tighten wording of
- message reported to user.
-
- Fixes <https://savannah.gnu.org/bugs/?59481>. Thanks to Dave
- Kemper for the report.
-
-2022-05-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PNMTOOLS_CAN_BE_QUIET)
- (GROFF_PNMTOPS_NOSETPAGE): Skip check if prerequisite not met.
-
-2022-05-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_URW_FONTS_CHECK): Rename this...
- (GROFF_URW_FONTS_NOTICE): ...to this.
- (GROFF_URW_FONTS): ...and this...
- (GROFF_URW_FONTS_CHECK): ...to this.
- (GROFF_URW_FONTS_NOTICE): Give lengthy notice message a one-line
- summary.
- * configure.ac: Update call sites.
-
-2022-05-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_URW_FONTS): Refactor. If our prerequisites
- are not met (availability of 'awk' and 'gs'), don't even run the
- check logic or print a "checking" message.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Handle missing programs required to construct files needed at
- runtime by gropdf more gracefully. Rename and refactor
- configuration-time logic to be more understandable.
-
- * configure.ac:
- * m4/groff.m4: Rename `GROFF_PDFDOC_PROGRAMS` macro to
- `GROFF_CHECK_GROPDF_PROGRAMS`. Rename shell variable
- `make_pdfdoc` to `use_gropdf`. Set it explicitly to "no" or
- "yes" instead of null or not null.
-
- * configure.ac:
- * m4/groff.m4:
- * doc/doc.am: Rename `BUILD_PDFDOC` to `USE_GROPDF`.
-
- * configure.ac: Call `GROFF_GROPDF_PROGRAM_NOTICE`.
-
- * doc/doc.am: Bracket definition of `PROCESSEDDOCFILES_PDF`
- macro and `$(PROCESSEDDOCFILES_PDF)` dependency declaration in
- Automake `if USE_GROPDF` conditional. This prevents attempts
- to build PDF documents using groff that are doomed to fail.
-
- * m4/groff.m4: Refactor gropdf runtime-dependency program check.
- Split into two macros: one (`GROFF_CHECK_GROPDF_PROGRAMS`)
- performs the check, the other (`GROFF_GROPDF_PROGRAM_NOTICE`)
- issues a notice at the end of the configuration process if at
- least one program was not found. Rename `docnote` shell
- variable to `gropdf_notice`. Tighten wording of notice. Drop
- unused `make_install_pdfdoc` and `make_uninstall_pdfdoc` shell
- variables.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Handle missing programs required at runtime by grohtml more
- gracefully. Rename and refactor configuration-time logic to be
- more understandable.
-
- * configure.ac:
- * m4/groff.m4: Rename `GROFF_HTML_PROGRAMS` macro to
- `GROFF_CHECK_GROHTML_PROGRAMS`. Rename shell variable
- `make_htmldoc` to `use_grohtml`. Set it explicitly to "no" or
- "yes" instead of null or not null.
-
- * configure.ac:
- * m4/groff.m4:
- * doc/doc.am: Rename `BUILD_HTML` to `USE_GROHTML`.
-
- * configure.ac: Call `GROFF_GROHTML_PROGRAM_NOTICE`.
-
- * doc/doc.am: Bracket definition of `PROCESSEDDOCFILES_HTML`
- macro and `$(PROCESSEDDOCFILES_HTML)` dependency declaration
- in Automake `if USE_GROHTML` conditional. This prevents an
- attempt to build an HTML version of the "pic.ms" document that
- is doomed to fail (noisily).
-
- * m4/groff.m4: Refactor grohtml runtime-dependency program
- check. Split into two macros: one
- {`GROFF_CHECK_GROHTML_PROGRAMS`} performs the check, the other
- {`GROFF_GROHTML_PROGRAM_NOTICE`} issues a notice at the end of
- the configuration process if at least one program was not found.
- Rename `html_docnote` shell variable to `grohtml_notice`.
- Tighten wording of notice. Drop unused `make_install_htmldoc`
- and `make_uninstall_htmldoc` shell variables.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_GHOSTSCRIPT_VERSION_NOTICE): Add newline at
- end of buggy Ghostscript notification, so that the multiple
- possible lengthy notices after the configuration report have
- blank lines separating them.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Check for m4 program at configuration time.
-
- * m4/groff.m4 (GROFF_PROG_M4): Define new macro to perform the
- check and error out if the program is missing.
- * configure.ac: Call the new macro.
- * tmac/tmac.am (tmac/groff_man.7.man)
- (tmac/groff_man_style.7.man): Use the new implicitly AC_SUBST-ed
- variable `M4` to run the program.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_PROG_YACC): Update wording of error
- message: we search for "yacc", so report it as missing if it is
- not found (along with "byacc" and "bison").
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: Fix shell style nits. Get rid of string
- {non-}nullity tests and comparisons involving concatenation with
- garbage (usually "x"). See 13 November entry regarding m4. Use
- idiomatic shell "brace style" for control structures.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Trivially refactor libgroff allocator configuration.
-
- * m4/groff.m4 (GROFF_USE_GROFF_ALLOCATOR): Update description of
- configuration flag to clarify that it's implemented in a
- library. Rename shell variable to prefix it with "groff_",
- putting it in an ad hoc name space as with other variables. If
- feature disabled, set variable to literal "no".
- * configure.ac: Use renamed variable and interpolate it directly
- into configuration report, simplifying shell logic.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: Revise configuration report for intelligibility.
- Add report of C++ compiler and flags used: we compile much more
- C++ than C code so this seems appropriate. Report Perl
- interpreter version so that we can collect build reports and
- turn the ratchet past Perl 5.6.1 at some point. Fix X11
- "resources" misnomer (application defaults are what is meant).
- Rephrase generally.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am (EXTRA_DIST): Ship "ChangeLog.122" in distribution
- archive. Overlooked in commit c11995df16, 19 February 2021.
-
-2022-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/grotty/tests/basic_latin_glyphs_map_correctly.sh:
- Fix portability problem: POSIX says that "od -c" (and "od -t c")
- are supposed to emit printing characters as defined by the
- underlying locale, but GNU coreutils od doesn't do this and
- macOS od does. Set `LC_ALL` to "C" when running it to force
- 3-digit octal reporting of characters with their eighth bit set.
-
- Fixes <https://savannah.gnu.org/bugs/?62357>. Thanks to John
- Gardner for the report. Also see <https://pubs.opengroup.org/\
- onlinepubs/9699919799/utilities/od.html>.
-
-2022-05-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * INSTALL.extra (In Case of Trouble): Add advice on using the
- test suite, particularly if it fails.
-
- Fixes <https://savannah.gnu.org/bugs/?62478> (one hopes).
-
-2022-05-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Input Line Traps): Expand discussion. The
- `it` and `itc` requests count neither input lines (strictly) nor
- text lines. Instead, they count input lines that _directly
- produce formatted output_ (and, in the case of `itc`, are not
- "interrupted" or continued with the `\c` escape sequence). This
- is useful--empty requests and requests that don't put nodes on
- the output don't break things--but does demand some explanation.
- Clarify and provide example.
- * man/groff.7.man (Escape sequence short reference) <it>: Sync.
-
-2022-05-18 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/env.cpp (environment::choose_breakpoint): Tweak
- diagnostic message ("can't" -> "cannot").
- * doc/groff.texi (Breaking): Update example.
-
-2022-05-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Copy Mode):
- * man/groff.7.man (Copy mode): Fix omission; `\?` is interpreted
- in copy mode.
-
-2022-05-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/s.tmac (PT): Unclutter name space; remove
- `pg*saved-page-number-format` string when we're done with it.
-
-2022-05-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Add unit tests, including one XFAIL for bad behavior.
-
- * src/preproc/tbl/tests/check-horizontal-line-length.sh:
- * src/preproc/tbl/tests/check-line-intersections.sh:
- * src/preproc/tbl/tests/check-vertical-line-length.sh:
- * src/preproc/tbl/tests/table-lacks-spurious-top-border.sh: Do
- it.
- * src/preproc/tbl/tbl.am (tbl_TESTS): Run tests.
- (tbl_XFAIL_TESTS, XFAIL_TESTS): Expect one test failure.
-
-2022-05-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/grotty/tty.cpp (tty_printer::add_char): Modify
- diagnostic message: what gets written "above [the] first line"
- might not be a character (glyph) per se, but a line (rule) from
- a drawing command, and in fact the occurrence of these from
- boxed tables is the most common cause of this message I've seen.
-
-2022-05-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grotty]: Do more input validation.
-
- * src/devices/grotty/tty.cpp (tty_printer::draw): Throw warning
- if an unsupported geometric primitive is encountered.
- (tty_printer::line): Throw warning if a line is diagonal. Die
- if length of a horizontal or vertical line is not a multiple of
- the appropriate motion quantum of the device (troff should never
- emit such nonsense, and currently doesn't appear to).
-
-2022-05-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/tbl/tbl.1.man (Miscellaneous): Document GNU tbl's
- use of `#T` and `T.` registers.
-
-2022-05-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (read_color_draw_node): Tweak
- diagnostic message to better distinguish drawing commands and
- device control commands.
-
-2022-05-14 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grohtml]: Mitigate double-free problem exposed by malformed
- input.
-
- * src/roff/troff/mtsm.h (struct statem): Place member variable
- `issue_no` behind `DEBUGGING` preprocessor symbol, omitting it
- from production and ordinary development builds.
- * src/roff/troff/mtsm.cpp (no_of_statems): Place global variable
- behind `DEBUGGING` preprocessor symbol, omitting it from
- production and ordinary development builds.
- (statem::statem): Make constructor trivial if `DEBUGGING` not
- defined in preprocessor; it manipulates only `issue_no` and
- `no_of_statems`, which are synchronized.
- (statem::statem {copy}): Gate assignment of `issue_no` member
- variable from copy constructor behind `DEBUGGING` preprocessor
- symbol.
- (statem::flush, mtsm::inherit): Gate debugging output, already
- runtime-gated on `debug_state` symbol, of `issue_no` member
- variable, so that we don't reference it when it is not declared.

-
- * src/preproc/refer/tests/artifacts/62124.ref: Rename this...

-
- * src/preproc/refer/command.cpp (process_commands): Begin
- migration to use existing global variables for location reports
- in diagnostic messages. Save current file name and line number
- before calling `command_loop()` and restore them afterward.
- Also decrement line counter before entering that loop because it
- would be too far advanced by one due to the final newline on a
- parsed input line.

-
- * src/preproc/refer/refer.cpp (main): Report system error on

-
- [refer]: Trivially refactor.
-
- * src/preproc/refer/command.cpp (input_stack::push_file):
- * src/preproc/refer/refer.cpp (do_file): Drop unnecessary
- construction of integer from integer (return type of `getc()`)
- in argument to error diagnostic functions; parallelizes with
- other diagnostic function calls.
-
-2022-05-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/refer/command.cpp: Refactor to simplify.
- (get_location): Demote return type from `int` to `void`. The

- (input_stack::error): Update call site to stop uselessly testing
- return value of `get_location()`.
-
-2022-05-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (dist-info-bits, install_infodoc, dist-gnueps): Fix
- logic error. When checking both source and build trees for
- files to copy, break after successfully copying the files, not
- after the first iteration of the loop unconditionally. This
- caused the Info documents not to be installed from out-of-tree
- builds, and potentially would prevent them and doc/gnu.eps from
- being included in the distribution archive if for some reason
- they didn't build and that build failure were not treated as an
- error. Problems introduced by me in commits e78bd20d54, 27
- March, and d79c3f3a4a, 11 November.
-
-2022-05-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_APPRESDIR_OPTION): Update comments and
- human-readable output to (1) stop claiming that existing
- gxditview application defaults in the installation directory
- will be backed up; this is no longer true as of commit
- c66cb7725f, 3 April; and (2) refer to these files as
- "application defaults", not "resources". (X11 application
- defaults are client-side and mandatory [for Xt-based programs];
- X resources are stored server-side and need not be configured to
- determine an X client's geometry and rendering.)

-
-2022-05-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devpdf/devpdf.am (font/devpdf/util/BuildFoundries): Spell
- dependency on `$(SH_DEPS_SED_SCRIPT)` using that macro expansion
- instead of a literal file name. See doc/automake.mom.
-

-
- * src/preproc/eqn/eqn.am (MAINTAINERCLEANFILES):
- * src/preproc/pic/pic.am (MAINTAINERCLEANFILES):
- * src/preproc/refer/refer.am (MAINTAINERCLEANFILES): Preserve
- byacc/bison output artifacts unless "maintainer-clean"ing. Per
- the GNU Automake manual, "The intermediate files generated by
- yacc (or lex) will be included in any distribution that is made.
- That way the user doesn’t need to have yacc or lex."
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am: Stop manually handling "test-groff". Per the
- GNU Automake manual, "If configure built it, then distclean
- should delete it." This is taken care of automatically if we
- don't interfere.
- (BUILT_SOURCES, MOSTLYCLEANFILES): Drop "test-groff".
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/eqn/eqn.am (neqn): Produce temporary file first
- and set its permissions before moving it into place. If
- anything in the future ever has a dependency on it, this avoids
- a race where the file exists, satisfying a dependency, but
- execution is attempted before its `x` permission bit is set.
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Ensure that we install *.me source files, but don't
- include them in the distribution archive.
-
- * doc/doc.am (dist_otherdoc_DATA): Move `$(GENERATEDDOCFILES)`
- from here...
- (nodist_otherdoc_DATA): ...to here.
- (.PRECIOUS): Add `$(GENERATEDDOCFILES)` so that make(1) doesn't
- automatically remove "intermediate" objects in the .me.in -> .me
- -> .ps chain.
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Handle "gnu.eps" file better.
-
- * doc/doc.am (GENERATEDDOCFILES): Remove `$(DOC_GNU_EPS)`.
- (EXTRA_DIST): Ship `$(DOC_GNU_EPS)` in distribution archive.
- ($(DOC_GNU_EPS)): Simplify rule commands; stop trying to copy
- the file around since it will either be (1) in the distribution
- archive from which a build is performed; or (2) missing because
- a build is being done from Git, in which case we expect the PNM
- tools to be available.
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (clean_otherdoc): Drop target: it doesn't seem to
- accomplish anything.
- (clean_infodoc): Drop target, moving its rules into...
- (maintainer-clean-local): ...this. Drop deps, both gone now.
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (distclean-local): Drop target: stop cleaning
- generated forms of our Texinfo manual with the "distclean"
- target. They ship with the distribution archive and should
- remain in the tree even if the user needs to re-./configure.
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Fix problems exposed by high build parallelism.
-
- * font/devpdf/devpdf.am (font/devpdf/util/BuildFoundries)
- (font/devpdf/DESC, font/devpdf/Foundry): Drop
- unnecessary removal of target prior to creating it.
- (font/devpdf/Foundry): Add creation of destination build
- directory as other targets do.
- (font/devpdf/download): Create dedicated target instead of
- lumping its generation under the stamp file. Add missing
- dependencies on `$(DEVPDFFONTMAP_1)`, `$(DEVPDFFONTMAP_2)`,
- `font/devpdf/Foundry` and `font/devpdf/enc/text.enc`. Remove
- now-unnecessarily complicated "forgery" of "GEN" line in quiet
- builds. Tweak format of comment written to "download" file to
- make field identities clearer. Construct output (with multiple
- shell commands) in temporary file so it is not read prematurely
- by the "BuildFoundries" script. Move target into place as the
- last step.
- (font/devpdf/stamp): Relocate target to follow its dependencies.
- Add dependency on "font/devpdf/download".
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Tweak diagnostic messages in BuildFoundries script.
-
- * font/devpdf/util/BuildFoundries.pl (LoadFoundry)
- (WriteDownload, CheckFoundry): Recast for specificity and
- consistent style.
- (Die): Stop reporting line number with fatal errors; none of the
- call sites are parsing input.
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [refer]: Fix off-by-one error in line number for some
- diagnostics.
-
- * src/preproc/refer/command.cpp (input_item::get_location):
- Decrement reported line number by one after looping over input
- so that we report the line number as it was before the last
- newline character seen. This off-by-one error was partially
- masked by...
- * src/preproc/refer/refer.cpp (do_file): ...initialization of
- `current_lineno` to zero. However, for syntax problems (as
- opposed to the semantic problems of refer(1) command
- processing), this could result in complaints about the line
- number before they occurred, even on "line zero". Initialize
- the variable to 1.
-
- Fixes <https://savannah.gnu.org/bugs/?62391>.
-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>

-
-2022-05-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/tfmtodit/tfmtodit.cpp (usage): Tweak usage message.
- Condense `-v` and `--version` into a single output line with
- brace and pipe notation, which we do not use in our man pages,
- but consistently do in our usage messages. Use lowercase for
- option arguments since they are separated from option flag
- letters by space. Call `fprintf()` once instead of 3 times.
-
-2022-05-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/refer/refer.cpp (main): Tweak wording of
- diagnostic messages to refer to options consistently and to
- characterize input as "invalid" rather than "bad".
- (usage): Document --version option. Use more informative
- metasyntactic variable names. Organize usage message
- consistently with our others, and stop wrapping the output
- lines: we know neither the width of the terminal nor the length
- of the `program_name` string we're interpolating. See commit
- b4de44f0, 19 July 2021.
-
-2022-05-01 G. Branden Robinson <g.branden.robinson@gmail.com>

-
-2022-05-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/refer/refer.cpp: Trivially refactor. Demote
- global variable `recognize_R1_R2` from integer to Boolean.
- (main, do_bib): Give expressions to `assert()` meaningful
- content.
- (is_list): Demote return type from `int` to `bool`.
- (do_file): Demote and rename integer local variables
- `start_of_line` to Boolean `at_start_of_line`.
- (is_list, do_file): Reorder equality comparisons to avoid
- inadvertent lvalue assignment.
-
-2022-05-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Reduce and rationalize in-tree document dependencies.
- This eliminates spurious rebuilds of numerous documents
- {including the 380+-page groff-man-pages collections}. It also
- fixes missing dependencies when using the build's groff to
- generate PostScript documents.
-
- * .gitignore: Drop old name of devpdf stamp file.
- * doc/.gitignore: Drop now-unused "example.stamp" file.
- * doc/doc.am (PROCESSEDDOCFILES_HTML, PROCESSEDDOCFILES_PDF)
- (PROCESSEDDOCFILES_TXT): Add new macros grouping targets by the

- foregeoing.
- (PROCESSEDFILES_DEPS_HTML, PROCESSEDFILES_DEPS_HTML,
- PROCESSEDFILES_DEPS_PDF, PROCESSEDFILES_DEPS_TXT): Add new
- macros defining prerequisites for production of the
- corresponding output document formats.
- ($(PROCESSEDDOCFILES_HTML), $(PROCESSEDDOCFILES_PDF),
- $(PROCESSEDDOCFILES_PS), $(PROCESSEDDOCFILES_TXT)): Declare the
- dependencies using expansions of the foregoing macros.
- (MOSTLYCLEANFILES): Drop "doc/automake.pdf", now part of
- `PROCESSEDDOCFILES_PDF`.
- (doc/automake.pdf): Drop dependencies already supplied by
- `PROCESSEDFILES_DEPS_PDF`.
- (HTMLDOCFILES): Drop macro. "doc/pic.html" is now in the
- expansion of `PROCESSEDDOCFILES_HTML`.
- (htmlpic_DATA): Redefine as expansion of
- `PROCESSEDDOCFILES_HTML` instead of `HTMLDOCFILES`.
- (PROCESSEDEXAMPLEFILES_HTML) [BUILD_HTML]: Define as
- "doc/webpage.html", otherwise as empty.
- (PROCESSEDEXAMPLEFILES_PS): Contain "doc/webpage.ps" and
- "doc/grnexampl.ps".
- (PROCESSEDEXAMPLEFILES): Redefine as expansions of
- `PROCESSEDEXAMPLEFILES_HTML` and `PROCESSEDEXAMPLEFILES_PS`.
- ($(PROCESSEDEXAMPLEFILES_HTML), $(PROCESSEDEXAMPLEFILES_PS)):
- Declare dependencies using `PROCESSEDFILES_DEPS_HTML` and
- `PROCESSEDFILES_DEPS_PS`, respectively.
- (HTMLEXAMPLEFILES): Drop macro. "doc/webpage.html" is now in
- the expansion of `PROCESSEDDOCFILES_HTML`.
- (nodist_htmlexamples_DATA): Drop macro, no longer needed.
- ($(PROCESSEDDOCFILES_PS)): Relocated and redefined above.
- ($(PROCESSEDEXAMPLEFILES) $(PROCESSEDDOCFILES)): Drop overbroad
- dependency declarations in favor of the above.
- (MOSTLYCLEANFILES, doc/examples.stamp): Drop generation and
- removal of unnecessary stamp file.

- required preprocessors. Drop redundant and spurious
- dependencies.
- * font/devhtml/devhtml.am (MOSTLYCLEANFILES)
- (font/devhtml/stamp): Generate and remove stamp file to enable
- reliable target dependencies for build-time generation of HTML
- documents by groff.
- * font/devpdf/devpdf.am (MOSTLYCLEANFILES, font/devpdf/stamp):
- Rename stamp file from "font/devpdf/build_font_files".
- (font/devpdf/stamp): Drop unnecessary dependency on "afmtodit".
- * font/devps/devps.am (MOSTLYCLEANFILES, font/devps/stamp):
- Generate and remove stamp file to enable reliable target
- dependencies for build-time generation of PostScript documents
- by groff.
- * font/devutf8/devutf8.am (MOSTLYCLEANFILES)

-
- [build]: Fix code style nits in Automake files.
-
- * doc/doc.am: Put spaces around (Auto)make variable assignments,
- for consistency with the rest of this .am file, and our others.
- * font/devpdf/devpdf.am (font/devpdf/build_font_files): Use
- shell '>' operator instead of touch(1).
- * font/devhtml/devhtml.am (font/devhtml/DESC):
- * font/devps/devps.am (font/devps/DESC): Construct target in
- temporary file, since doing so is a multi-step process, moving
- it to the target name when it is complete and usable by
- dependencies.
-
-2022-04-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/refer/refer.cpp (main): When complaining of

- the leading dash), not just its first character.
-
-2022-04-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libgroff/error.cpp: Trivially refactor. Explicitly
- compare pointer lvalues to null pointers instead of punningly
- treating them as Booleans. Annotate use of zero literals as
- null pointers to ease any future migration to ISO C++11.
-
-2022-04-27 G. Branden Robinson <g.branden.robinson@gmail.com>

-2022-04-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Refactor to simplify. Ingo's removal of the
- "--with-doc" "configure" option, among other changes, clears the
- way to remove many phony targets and simplify dependencies
- involving generation of the 5 formats of our Texinfo manual.
- (build_infodoc, doc, doc_all, doc_txt, dvi, doc_dvi, pdf,
- doc_pdf, html, doc_html): Drop phony targets.
- (all): Depend directly on doc/groff.{info,txt,html,dvi,pdf}.
- * NEWS: Add item since "make doc" is no longer necessary and
- will do nothing.

-
- [tbl]: Handle `\R` sequences in text blocks robustly.
-
- * src/preproc/tbl/table.cpp (table::add_entry): Fix SEGV when
- repeating glyph table entry syntax (`\Rx`) used in a text block.
- Lift extraction of entry string to be done unconditionally,
- rather than in 5 different special cases. This frees us up to
- rewrite the entry if necessary, changing '\R' to '\&' inside a
- text block. Recast diagnostic to describe the problem
- clearly--"bad repeated character" suggests that something is
- wrong with the "argument" to `\R`, when really the problem is

-
-2022-04-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/refer/label.ypp: Drop redundant declaration of

-
- * src/preproc/grn/hdb.cpp (DBGetType): Lower fatal diagnostics

- * src/preproc/grn/hdb.cpp (DBRead): Add more validity checking.
- Verify that the number of conversions returned by fscanf() is as
- expected instead of throwing this information away--abort

- [man]: Fix extraneous space in output after `ME` or `UE` when
- mandoc wrapper is used.
-
- * tmac/an-ext.tmac (UE, ME): Double backslashes in macro
- definitions when interpolating `.$` register (just like we tell
- everyone else to do). This one was interesting to track down.
- When using just `-man`, the problem never manifested; only with
- `-mandoc`. The difference is that with the former, the `.$`
- register is initialized to zero; with the latter, because `TH`
- is aliased to another macro (then unaliased), `.$` has the
- argument count to the `TH` macro, not to the macros actually
- being called. This caused the wrong branch of a conditional to
- be taken and put an extra space node on the output.

-
- Fix the configuration of texi2dvi.
-
- * m4/groff.m4: Set groff_have_texi2dvi if texi2dvi(1) is
- available and usable, even if the availability was specified by
- the user by manually providing the configure variable
- PROG_TEXI2DVI, and not only if it was autodetected.
- Also, set the PROG_TEXI2DVI Makefile variable to the name of
- the texi2dvi program specified by the user or autodetected,
- and not to the string "found", such that this Makefile variable
- can be used for invoking the program.
- * doc/doc.am: Call the texi2dvi program specified by the user
- or autodetected rather than hardcoding "texi2dvi". This lets
- the groff build succeed on systems where the first texi2dvi
- in the $PATH is an old version unfit for groff's purposes.

-
-2022-04-06 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Drop unnecessary `-I` options to groff.
- (DOC_GROFF): There is no need to look at the top of the build
- directory for any file inclusions.
- (doc/webpage.html): There is no need to look in `doc_builddir`
- for file inclusions, since that is the current working directory
- when "webpage.ms" is processed.
-
-2022-04-06 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Trivially refactor. Use `RM` macro idiomatically.
- Automake ensures that it is defined to call an `rm` command with
- the `-f` option, and this in turn ignores failures to delete
- nonexistent files, so...
- (uninstall_doc_examples, uninstall-pdf): Stop adding superfluous
- `-f` flag.
- (clean_infodoc uninstall-pdf, uninstall-html): Stop prefixing
- command with `-` to ignore error exit status.
- (uninstall-html): Drop superfluous `-r` flag; we're only
- deleting files with this command, not directories.
-
-2022-04-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Trivially refactor shell style in rule commands.
- The placement of `&&` was inconsistent. Always begin a
- continued rule line with it, and don't give it its own
- indentation level. In general, operators adjacent to line
- continuations should _follow_ the continuations because they are
- easier for humans to spot at the (possibly indented) beginning
- of a physical line.
-
-2022-04-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am: Rename `TFLAG` macro, which means "tmac flag", to
- `MFLAG`, because it expands to `-M` options to groff, not the
- `-T` option, which can be bewildering.
- * doc/doc.am (DOC_GROFF): Update expansion site.
-
-2022-03-29 G. Branden Robinson <g.branden.robinson@gmail.com>

-
-2022-03-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Refactor. Drop ghastly hack used to get file
- names into troff diagnostics when reading from standard input.
- We've refactored so that it no longer does, making the hack
- unnecessary. For the same reason, no users of the `DOC_GROFF`
- macro remain, so delete it. Add comments to explain what
- `DOC_SED` and `DOC_GROFF_ONLY` are for.
-
-2022-03-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Refactor.
- (doc/pic.html, doc/webpage.html): Drop indirection of source
- document through `DOC_SED` macro. It was not necessary since
- neither of these documents are parameterized in configuration
- options (that is, they don't contain @VERSION@ or @g@).
-
-2022-04-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Trivially refactor.
- (doc/webpage.html): Tidy up dependency list. Create directory
- using the same macro interpolation we use to change into it.
-
-2022-04-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Refactor and fix error in builds in remote
- out-of-source-tree builds exposed by pending commit and `make
- distcheck`. The images generated for the pic.html and
- webpage.html files were being built in the wrong directory, and
- subsequently not found by an install rule.
- (imagedir): Add comment explaining purpose of macro. It should
- _not_ be used with any file specifications relative to the
- source or build trees--it is for installation directories only.
- (htmldocimagedir, exampleimagedir): Drop macros.
-
- (doc/pic.html, doc/webpage.html): Replace interpolations of
- `imagedir` with literal "img", since these files are being
- generated within the build tree: the directory name is known.
-
- (mostlyclean_doc, install_doc_htmldoc, install_doc_examples):
- Replace interpolations of `htmldocimagedir` relative to
- `doc_builddir` with "img" literals.
-
- (install_doc_htmldoc, uninstall_doc_htmldoc): Interpolate
- concatenation of `htmldocdir` and `imagedir` instead of
- `htmldocimagedir` (relative to `DESTDIR`).
- (install_doc_examples, uninstall_doc_examples): Interpolate
- concatenation of `exampledir` and `imagedir` instead of
- `exampleimagedir` (relative to `DESTDIR`).
-
-2022-04-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Refactor. Relocate "doc/grnexampl.ps" target to
- group it with other me(7) documents. Put addition of
- "doc/examples.stamp" to `MOSTLYCLEANFILES` adjacent to its
- target rule. Relocate same rule so that it precedes the target
- depending on it (make(1) might not benefit from this, but human
- readers can).
-
-2022-03-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Refactor.
- (DOC_GROFF_ONLY): Drop preprocessor options from groff command.
- This macro is now, simply, a way to run the in-tree groff: no
- assumptions about preprocessors, macro packages, or output
- device are made.
- (doc/pic.html, doc/webpage.html): Add only necessary
- preprocessor options after expansion of `DOC_GROFF_ONLY`.
-
-2022-03-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Refactor. Add explicit dependencies of compiled
- man page documents on preprocessors needed to generate them. In
- their target rules, explicitly use groff's preprocessor options,
- freeing us up to simplify the `DOC_GROFF_ONLY` macro.
-
-2022-03-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Rationalize dependencies. Drop dependency of
- `PROCESSEDEXAMPLEFILES` and `PROCESSEDDOCFILES` on expansion of
- `hdtbltmac_DATA`, because nothing in this directory uses the
- hdtbl package. Move dep of same expansions on "gnu.eps" to
- "doc/webpage.html", which actually uses it. Put the numerous
- dependencies of "doc/pic.html" and "doc/webpage.html" in a
- parallel ordering so that they are easier for humans to
- evaluate. These targets' dependencies on `bin_PROGRAMS` and
- `prefixexecbin_PROGRAMS` are overkill and should be reviewed at
- a later date.
-
-2022-04-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Refactor use of target and suffix rules.
- (doc/meintro.me, doc/meintro_fr.me, doc/meref.me): Add target
- rules, with lengthy, exasperated comment about lack of feature
- parity in various make(1) implementations.
- (doc/meintro_fr.ps): Add target rule, as this seems to be the
- only way to keep GNU Make from ignoring a '_fr.me._fr.ps' suffix
- rule in favor of '.me.ps', which doesn't call preconv (and
- doesn't need to--and moreover we don't want to build English
- me(7) documents with the `-mfr` option). Depend on `preconv`.
- (doc/webpage.ps): Convert from suffix rule to target rule.
- (doc/ms.ps, doc/pic.ps, doc/webpage.ps): Add target rules and
- dependencies.
- (.ms.ps): Add commented-out suffix rule (since nothing uses it,
- but might in the future).
- (doc/meintro_fr.ps, .me.ps, doc/pic.ps, doc/webpage.ps): Migrate
- expansions of `DOC_GROFF` to `DOC_GROFF_ONLY` to prepare for a
- forthcoming simplification.
-
-2022-04-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Clean generated doc files better. doc/me*.me were
- getting left behind in the build tree.
- (MOSTLYCLEANFILES): Add `GENERATEDDOCFILES`. This includes
- `DOC_GNU_EPS`, so...
- (clean_maintdoc): Drop phony target that manually removes it.
- (maintainer-clean-local): Drop dependency on foregoing.
-
-2022-04-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/xditview/xditview.am (install_xditview)
- [!WITHOUT_X11]: Stop backing up existing "GXditview" and
- "GXditview-color" application defaults files. There is no
- symmetric restoration of them in the uninstall target, and it
- seems like unjustifiable complexity to add such. These are
- groff-specific file names, installed (by default) to /usr,
- not /etc, so they are not going to be "configuration files" in
- Debian-based systems, for example (and likely not elsewhere).
- There are other ways to supersede application defaults for
- programs using the X Toolkit Intrinsics.
-
-2022-04-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Stop treating "gnu.eps" as an "example" file; it
- is also used by pdfmark's cover.ms, which is ordinary
- documentation. We therefore must not omit it when building.
- (install-data-hook): Add dependency on new phony target,
- "install_doc_gnu_eps".
- (install_doc_examples): Move installation of "gnu.eps" from
- here...
- (install_doc_gnu_eps): ...to here. Also refactor the loop we
- use to locate the file to follow a more idiomatic pattern.
-

-
- [doc]: Refactor handling of "gnu.eps" file.
-
- * doc/doc.am: Put "gnu.eps" in a Make macro, `DOC_GNU_EPS`.
- ($(PROCESSEDEXAMPLEFILES) $(PROCESSEDDOCFILES),
- doc/webpage.html, install_doc_examples): Migrate dependency to
- `DOC_GNU_EPS`.
- (doc/webpage.ps): Add (missing) dependency on `DOC_GNU_EPS`.
- (DOC_GROFF_ONLY): Drop `-I` flag; it's not necessary given the
- following.
- (.ms.ps): Drop `-mwww` argument from suffix rule. A truly
- generic ms document won't need it.
- (doc/webpage.ps): Add target rule. Include `-mwww` argument.
- (doc/webpage.ps, doc/webpage.html): Pass `-I` option to
- `DOC_GROFF` and `DOC_GROFF_ONLY` (respectively) to enable
- location of "gnu.eps" file. Search the build and source trees'
- "doc" directories because the file can be generated as part of
- the build or can come with the distribution archive.
- (EXTRA_DIST): Drop redundant inclusion of "doc/gnu.xpm".
- (clean_maintdoc): Add phony target to dispose of `DOC_GNU_EPS`.
- (maintainer-clean-local): Depend on "clean_maintdoc".
-
- * tmac/tests/pdfpic_does-not-choke-on-bad-pdfinfo-output.sh:
- * tmac/tests/pdfpic_falls-back-to-PSPIC.sh: Update tests to look
- for "gnu.eps" in "doc" directory of build tree. Give generated
- files distinguishable names so their tests can run concurrently.
-
-2022-03-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Add new macro `PROCESSEDDOCFILES_PS` to isolate
- names of targets in PostScript format. Expand this macro in
- definition of `PROCESSEDDOCFILES` and use it to move PostScript
- font description file dependencies of the latter and
- `PROCESSEDEXAMPLEFILES` to the former. (At present, the
- dependency might seem superfluous, since those files are in the
- source distribution, but it's conceivable that in the near
- future, they will be produced at build time from Adobe font
- metric files; see font/devps/generate/Makefile). The "pic.html"
- and "webpage.html" targets already had such a dependency because
- of the way grohtml (pre-grohtml) works.
-

-
- * doc/doc.am: fix non-portable syntax in the doc/me*.me targets:
- POSIX does not define the meaning of $< in non-suffix rules, so
- use the portable $? instead. This is adequate here because each
- of these three rules has exactly one prerequisite.

-
- * doc/doc.am: fix non-portable syntax in the groff-man-pages.*
- targets by using DOC_GROFF_ONLY rather than DOC_GROFF in order
- to not use $< outside a suffix rule; DOC_GROFF functionality is
- not needed here in the first place.

- [preconv]: Trivially refactor.
-
- * src/preproc/preconv/preconv.cpp: Use diagnostic message
- functions from libgroff where possible. Explain in a comment
- why we don't use `debug()`. Boolify and rename some variables,
- and use Boolean literals to assign to them.
- debug_flag -> is_debugging
- invalid_warning -> emit_invalid_utf8_warning
- incomplete_warning -> emit_incomplete_utf8_warning
- Rename `expected_bytes` to `expected_byte_count`. Except for
- the debugging flag, these are all members of `struct
- conversion`.
- (get_tag_lines): Migrate to `warning()`.
- (detect_file_encoding): Migrate to `error()` and `fatal()`, as
- appropriate.
- (utf8::invalid, utf8::incomplete, get_tag_lines): Don't break a
- line in the middle of a diagnostic; doing so frustrates grepping
- and necessarily makes an assumption about the terminal width.

- [tbl]: Fix Savannah #62191.
-
- * src/preproc/tbl/main.cpp (table_input::get): Increment input
- line counter when encountering an escaped newline; this fixes
- inaccurate diagnostics from the formatter at any point in a
- document after a line-continued row of table data. Also drop a
- "perhaps" comment. I tested the surmise (setting the FSM state
- to "START"), and it results in bad formatting.

- * tmac/e.tmac: Test register for existence before using it to
- set hyphenation mode. A site troffrc or other local
- customization might remove the register (which is guaranteed to
- be set under the stock configuration) and, perversely, Heirloom
- Doctools troff interprets a `do` request, instead of ignoring it
- as a historical troff implementation would, so if they borrow
- our me(7) changes, the register would be unset, interpolate
- zero, and hyphenation would wind up disabled.

- * font/devps/devps.am: Rename targets.
- (fonts):
- (devps_fonts): Rename these...
- (maintainer-font-descriptions):
- (devps_font-descriptions): ...to these. Add comments explaining
- what they're for and why they aren't used in a build.
-
- * font/devps/generate/Makefile: Add `outdir` variable to store
- destination directory of font description files, and update all
- targets that write artifacts to use this directory. This makes
- the targets "phony", which I don't regard as a problem since the
- generated artifacts are kept under source control, and this
- isn't really a user-facing script (even though it gets
- installed). I think there is a good chance that this will
- become a shell script, because to avoid regressions we need to
- generate the font descriptions using both the 229-glyph and
- 314-glyph versions of the Adobe fonts' AFM files (so that we get
- wider glyph coverage _and_ more kerning pair data) and we need
- to add kerning information for the ellipsis (Savannah #58897).
- (symbolsl.afm): Revise generation process to be sensitive to
- failure.
-
-2022-03-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * font/devps/symbolsl.afm: New file.
- * font/devps/devps.am (EXTRA_DIST): We have long shipped
- "symbol.afm" with the distribution archive--I don't see why we
- don't ship "symbolsl.afm" and "zapfdr.afm" as well (metrics for
- `SS`, the slanted symbol font, and ZDR, reversed Zapf Dingbats).
- Like the Type 1 font descriptions themselves, this file is
- updated only in "maintainer mode", not as part of the build.
- Moreover, these fonts are not part of the PostScript level 2
- base 35 fonts so their AFM files are unlikely to be readily
- available elsewhere.

-
- * src/utils/afmtodit/afmtodit.pl: Trivially refactor. Store the

- that in the usage message and comment embedded in the output.
-
-2022-03-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/afmtodit/afmtodit.pl: Fix code style nits. Migrate
- to the shebang line style we use in more recently modified Perl
- scripts. Replace `-w` with `use warnings;`. Shorten an output
- comment since the groff version string can grow long (see commit
- 1264531310, 14 January 2018).
-
-2022-03-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-

- Kemper for the discussion and code review.

-
-2022-03-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/X.tmac: Redirect `fchar` requests for \[lq] and \[rq] to
- \[dq] since the X11 Type 1-based text fonts encode ISO 8859-1
- {Latin-1} and don't have typopgrapher's quotes. Drop `fchar`

-
- * src/roff/troff/input.cpp (get_char_for_escape_name): Recast
- diagnostic messages to more accurately refer to escape
- "sequence" rather than "name". "Name" is a confusing term here,
- given that it also applies to a group of objects sharing a name
- space (natch): requests, macros, strings, and diversions.
- Further, the "escape name" cited by these diagnostics is not the
- escape function selector; that is, the character after the
- escape character which determines how the escape sequence is to
- be interpreted. These diagnostics are only thrown after that
- function is known, however, when parsing of an escape sequence
- parameter is attempted.
- (input_char_description): Drop leading articles ("a") from

- * src/roff/troff/number.cpp (start_number): Say "numeric
- expression missing" instead of "missing number"; we don't
- require a terminal symbol in the expression grammar here. Also

-
- * src/roff/troff/div.cpp
- (top_level_diversion::transparent_output):
- * src/roff/troff/input.cpp (transparent_translate): Suppress two
- troublesome (i.e., more or less spurious) error diagnostics
- about transparent output/throughput unless the environment
- variable `GROFF_ENABLE_TRANSPARENCY_WARNINGS` is present. This
- is a bit of a bodge until we get diversion sanitization worked
- out. See Savannah #61407.

-
- [preconv]: Stop assuming that the default input stream, or an
- explicit '-' operand, is the only unseekable stream. Check
- instead.
-
- * src/preproc/preconv/preconv.cpp (do_file): Add new Boolean
- `is_seekable`. Test the input stream with `fseek()` per a
- suggestion from Ingo Schwarze. Report unseekability in debug
- output and skip coding tag and uchardet tests altogether
- {precisely paralleling our description in the preconv(1) man
- page}. Also update debugging output to say "<standard input>"
- instead of "-".

-
- Refactor X11 font description generation. Integrate it with our
- "new" (post-2014) Automake-based build system.
-
- * src/utils/xtotroff/Makefile.in: Delete relic of old build
- system. Also, it had a bug: it generated X11 output device
- 'DESC' files with a "unitwidth 10" directive even for the "-12"
- devices, which is not correct (the in-tree DESC files we've been
- shipping for years were nevertheless correct, apparently fixed
- by hand by James Clark in groff 1.07 [March 1993]).
-
- * src/utils/xtotroff/xtotroff.am: Define `xtotroff` variable for
- use by X11 font description generation targets below.
-
- * font/devX100-12/devX100-12.am:
- * font/devX100/devX100.am:
- * font/devX75-12/devX75-12.am:
- * font/devX75/devX75.am: Add new (phony) targets, variously
- named "devX{100,100_12,75,75_12}", to generate the corresponding
- output device's DESC file and run xtotroff(1) to generate its
- font description files. Be sure to set the correct "unitwidth"
- for the "-12" devices. Add new dependency-only rule
- "maintainer-font-descriptions" depending on these new targets
- for convenience (and future expansion to devps and devlj4).
-
- * FOR-RELEASE: Document existence of
- "maintainer-font-descriptions" Make target and when to run it.
-
- Running this target with the aforementioned bug fix, overwriting
- the in-tree DESC and font description files using data gathered
- from a running X server, results in no changes whatsoever. Say
- what you will about X11 core font technology--it's stable.
-
-2022-02-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Rename and ship "FontMap-X11". xtotroff(1) is not very useful
- without a font name mapping file to read. To date it has been
- available only in the source distribution. Remedy that. The
- file is placed directly in the groff font directory alongside
- the device directories because it applies to four different
- devices, and four copies of this data are not required.
-
- * src/devices/xditview/FontMap: Rename to...
- * src/devices/xditview/FontMap-X11: ...this.
-
- * LICENSES:
- * src/devices/xditview/xditview.am (EXTRA_DIST): Reflect rename.
-
- * src/devices/xditview/xditview.am (install_xditview
- [!WITHOUT_X11], uninstall_xtdiview): (Un-)install it.
-
- * src/utils/xtotroff/xtotroff.1.man (Files): Add section
- documenting the presence and purpose of this file.
-
-2022-02-26 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [xtotroff]: Add `-d` option to produce font description files in
- specified directory.
-
- * src/utils/xtotroff/xtotroff.c: Do it. Add global `destdir`
- pointer.
- (xtotroff_exit): Add new function to clean up storage allocated
- by `strdup()` (below) for destination directory.
- (MapFont): Introduce new variable `file_name`, into which we
- assemble a destination file name from `destdir` (if not null)
- and the troff font name. Handle memory allocation failure (by
- carefully dying). Free allocated storage on success and failure
- paths out of the function.
- (usage): Document new `-d` option.
- (main): Instruct `getopt_long` to expect a `-d` flag with an
- argument. Use `strdup()` to make a copy of any such option
- argument. Call `xtotroff_exit()` instead of `exit()`.
-
- * src/utils/xtotroff/xtotroff.1.man: Document new `-d` option.
-
-2022-02-26 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [xtotroff]: Trivially refactor.
-
- * src/utils/xtotroff/xtotroff.c: Boolify. Include `stdbool.h`
- and `errno.h` headers.
- (charExists, CanonicalizeFontName, FontNamesAmbiguous, MapFont):
- Boolify. Demote return type from `int` to `bool` and return
- Boolean instead of integer literals.
- (FontNamesAmbiguous, main): Reorder equality comparisons with
- simple left-hand sides to avoid inadvertent lvalue assignments.
- (FontNamesAmbiguous, MapFont): Refer to font name as "invalid",
- not "bad", in diagnostic messages.
- (MapFont, main): Use `strerror()` instead of `perror()` so that
- diagnostics include the program name and an indication of
- problem severity.
- (MapFont): Compare `FILE` stream pointer to `NULL` instead of
- treating it as a Boolean.
- (main): Use `EXIT_SUCCESS` and `EXIT_FAILURE` constants from C
- library instead of integer literals for exit status.
-

-
- [pic]: Fix "unused result" compiler warning.
-
- * src/preproc/pic/pic.ypp (placeless_element) <SH>: Check return

- is less than zero, report it to the standard error stream.

-
-2022-02-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/doc.tmac (Tn):
- * tmac/mdoc/doc-syms (Ux, Bx): Stop interpolating string
- `doc-Tn-font-size` to set macro arguments at a smaller type
- size. This leaves the string without a purpose, so...
-
- * tmac/mdoc/doc-ditroff:
- * tmac/mdoc/doc-nroff: Drop definitions of `doc-Tn-font-size`.

-
- Revert addition of man(7) `BD` register. This feature, which I
- introduced in commit ea3b27102f (31 January) doesn't work
- because pdf.tmac normalizes the bookmark depth. Embedding a man
- page in a larger PDF document with appropriately nested
- bookmarks is a project that will have to await another day (or
- perhaps already has tools to implement it).
-
- * tmac/an.tmac: Do it.

-
-2022-02-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-

-
- [man,mdoc,me]: Revise hyphenation localization.
-
- * tmac/an.tmac (an*reset-hyphenation-mode): New macro sets the
- hyphenation mode appropriate to the locale depending on the
- values of `cR` (continuous rendering mode) and `HY` (hyphenation
- enablement); the latter is now interpreted as a Boolean. Define
- new register `an*hyphenation-mode` reflecting these conditions.
- (TH): Call the foregoing instead of invoking `hy` request.
- (MR): Restore hyphenation mode to `an*hyphenation-mode`.
- (initialization): Simplify; if not defined, set `HY` to 1.
-
- * tmac/e.tmac (ld): Set the hyphenation mode here instead of in
- initialization (which already calls this macro). Set the mode
- to 6 for the benefit of anyone borrowing our me(7) changes, but
- then immediately change to the mode determined by the
- localization file.
-
- * tmac/mdoc/doc-common (doc-hyphen-flags): Set a hyphenation
- mode appropriate to the locale, depending on the values of `cR`
- and `HY`.
- * tmac/mdoc/doc-ditroff:
- * tmac/mdoc/doc-nroff: Simplify initialization; if not defined,
- set `HY` to 1.
-
- * tmac/cs.tmac:
- * tmac/de.tmac:
- * tmac/en.tmac:
- * tmac/fr.tmac:
- * tmac/it.tmac:
- * tmac/sv.tmac: Before switching locales, set a flag if
- troublesome value 2 of the hyphenation mode is set so that we
- can preserve it. Shift man(7) and me(7) logic to follow setup
- of the new hyphenation mode; for the former, call the new
- `an*reset-hyphenation-mode`.
-
- * tmac/groff_man.7.man.in:
- * tmac/groff_mdoc.7.man: Document updated meaning of `HY`
- register.
-
- * NEWS: Add item noting change of man(7) `HY`'s meaning. Update
- existing item regarding mdoc(7)'s support for it (groff 1.22.4
- mdoc(7) didn't recognize the register at all).

-
- * Makefile.am (.man): Prefix hyphenation control escape
- sequences to more configuration-time interpolations to prevent
- their hyphenation: @DEVICE@, @g@, @INDEX_SUFFIX@, @PAGE@,
- @TMAC_{AN,M,S}_PREFIX@, @TMAC_MDIR@.
-
-2022-02-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man]: Refactor `EX` and `EE` macros.
-
- * tmac/an-ext.tmac: Add new `mC` string to store the font name
- to be used for example regions. In AT&T device-independent
- troff, "CW" was a common name, so use that. It is however a
- terrible fit for groff's font family and style-combination
- functionality, and is inflexible in the face of font selection
- requests and escape sequences within the example region. (One
- either needs to know the names of the fonts available on the
- output device, or suffer the indignity of mixed constant-width
- and proportional typefaces.) Relatedly, drop groff-specific
- font remapping requests.
- (EX, EE): Ignore definition if GNU troff is the formatter. Drop
- font family manipulation. Drop specialized logic for groff's
- DVI output device.
-
- * tmac/an.tmac (initialization): Resurrect font remapping
- requests here.
- (EX, EE): Add new definitions, saving and restoring more state
- and remapping DVI output device fonts to reflect the absence of
- CWB and CWBI faces.
-
-2022-02-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-ext.tmac: Slightly refactor. Stop using groff's `HY`
- register to restore the hyphenation mode, since I plan to change
- its semantics to a Boolean value (see Savannah #61734).
- Introduce new register `mJ` to store "1" (if not groff) and the
- current hyphenation mode otherwise. Explain why in a comment.
- (YS, UE, ME, MR): Restore hyphenation mode using `mJ` instead of
- `HY`.
-
-2022-02-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-ext.tmac: Trivially refactor. Use a better idiom
- {seen in James Clark's changes to BSD me(7)} for conditionally
- defining a (simple) macro.

- directory conventions.
-
-2022-02-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/pdfpic.tmac: Search for temporary directories as groff(1)
- does, instead of going straight to /tmp.
- (pdfpic@get-temporary-directory): New function checks each of
- its arguments for validity as a temporary directory; if one is
- found, its name is left in `pdfpic*temporary-directory`.
- (pdfpic@cleanup): Remove strings `pdfpic*temporary-directory`
- and `pdfpic*temporary-file`.
- (PDFPIC): Call `pdfpic@get-temporary-directory`, using the
- contents of the environment variables $GROFF_TMPDIR and $TMPDIR,
- and then /tmp, in that order. Store the temporary file name in
- string `pdfpic*temporary-file`. Use this string in subsequent
- `sy` and `so` requests.

-
- [tests]: Tweak PDFPIC test input.
-
- * tmac/tests/pdfpic_does-not-choke-on-bad-pdfinfo-output.sh:
- Eliminate unnecessary blank lines from input. Also call gs(1)
- with '-q' in addition to '-o'. (Why does the latter not imply
- the former?!) Thanks to Deri James for the advice.
-
-2022-02-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/pdfpic.tmac: Slightly refactor.
- (pdfpic@cleanup, PDFPIC): Rename `pdfpic*file-name` to
- `pdfpic*file-name-base` since it is not used as a complete file
- name (but rather a basis for an ".eps" extension).
- (PDFPIC): When testing PDF file extension, include the "."; a
- file name like "mxyzptlkpdf" is too dubious to accept. Also
- explicitly compare `systat` register as equal or not equal to
- zero, since its truth value is inverted from the expectations of
- *roff expressions.
-
-2022-02-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/pdfpic.tmac (PDFPIC): Refactor PDFPIC_NOSPACE handling.
- Stop shelling out to create, and then sourcing, a temporary file
- just to obtain the value of an environment variable. groff
- already has the `\V` escape sequence for that purpose (it's even
- safe!). Check that the value of $GROFF_PDFPIC_NOSPACE is a
- valid numeric expression before assigning it to a register.
- Trivially, use '=' instead of '==' as an equality operator.
- *roff languages do not use '=' as an assignment operator, and I
- believe the '==' synonym to be a sop to C programmers.
-

-
- [me]: Add nroff mode fallback for `u` macro.
-
- * tmac/e.tmac (u): On nroff devices, bracket the first argument
- with \(ul (underline rule) special character escape sequences.
- {In plain language, '.u "like this"' renders "_like this_".}
-
- I regard this as a cosmetic and semantic improvement; since the
- quarter-em vertical motions used in troff mode were ignored in
- nroff mode, the effect was not underlining but a sort of
- strike-through, visible only at spaces in the argument. The use
- of this macro was thus invisible in nroff output if no spaces
- were present in the argument. This is probably the best we can
- do without a fatter interface to terminal device capabilities.

- Condense diagnostic emission using the @error macro instead of

-
- [man]: Refactor PDF bookmark support.
-
- * tmac/an.tmac (an*bookmark): New internal macro calls
- `pdfbookmark` (only if the output device is 'pdf').
- (initialization): Migrate macro appendments to appropriate
- definitions. Two cases...
- (SH, SS): ...were straightforward.
- (initialization): Another (for the man page title) was poorly
- placed when appended to the `TH` macro, skipping over the page
- header. Move it instead...
- (PT): ...here. But to keep this bookmark from being generated
- on every page of a document, we need a new variable
- `an*was-TH-bookmark-emitted` which is tested here and assigned
- once one bookmark corresponding to a `TH` call has been written.
- (TH): Initialize `an*was-TH-bookmark-emitted` to zero.
- (SS): Write the bookmark _before_ the subsection heading text.
- (initialization): Drop short-lived `BM` register. It seems
- harmless to unconditionally include bookmarks in PDF output. A
- PDF tool can strip them out if they're not desired, and viewers
- seem capable of minimizing or reducing the navigation pane (if
- they even offer one in the first place).
-
- * tmac/an.tmac (initialization): Rename new `BN` register to
- `BD`...
- * tmac/groff_man.7.man.in (Options) <BD>: ...and document it.
- Also document `PT`'s new bookmarking responsibility.

- * src/roff/troff/input.cpp (usage): Partly revert commit

- run without operands.
-
-2022-01-31 G. Branden Robinson <g.branden.robinson@gmail.com>

- environment.
-
- (an-header): Update call site of `an*prepare-page-title`.
-
- (TH): Move planting of `an-header` trap from out of the midst of
- footer trap management. Add comments.
-
- (an-header): Move `pl` and `sp` requests from here...
- (PT): ...to here. While it's conceptually nice to have these
- macros consist solely of `tl` requests, it doesn't yield enough
- power to those who want to redefine them. Add comment.

-
- Implement PDF bookmark support for man pages. Limitation: A
- {sub}section can only be bookmarked if it is specified in the
- arguments to the `SH` or `SS` requests, not on the next line in
- an input trap. Thanks to Deri James for providing the
- fundamentals (blame me for any weird bits).
-
- * tmac/an.tmac (an-prepare-page-title): Define a new string,
- `an*page-ref-string`, which is the man page's own reference
- {such as "groff(1)"} without any abbreviation, ellipsis, or font
- selection or italic correction escape sequences.
- (SS): Define a new string, `an*subsection-heading`, storing the
- macro arguments (if any). These could contain font selection
- escape sequences, for instance, a fact that becomes important
- later.
- (initialization):
- - Recognize `BM` register to enable PDF bookmarks (only on the
- 'pdf' output device); defaults on. Recognize `BN` register to
- set a base level/depth for the bookmarks; this is to ease
- embedding of man pages in other PDF documents that already use
- bookmarks. The default is 0. The registers are not yet
- documented.
- - If the output device is 'pdf' and bookmarks are enabled, set
- `PDFOUTLINE.FOLDLEVEL` and `PDFHREF.VIEW.LEADING` registers
- {recognized by 'pdf.tmac'}. Append to `TH`, `SH`, `SS` to get
- the `an*page-ref-string`, `an-section-heading`, and
- `an*subsection-heading` bookmarks in the document at the
- applicable levels.
-
- * tmac/mdoc/doc-common: Add straw-man implementation--it doesn't
- support the `BM` and `BN` configuration parameters yet. (This
- is enough to get bookmarks for the groff_mdoc(7) page to
- correctly appear in the new 'groff-man-pages.pdf' document.)
- (Dt, Sh, Ss): If the output device is 'pdf', place bookmarks in
- the document at levels 1, 2, and 3.

-
-2022-01-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/trans.tmac: Further follow up commit c64fd60dff. If the
- `andoc` wrapper is being used, perform man(7) localization (not
- just when `an` is loaded).
-
-2022-01-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man pages]: Fix options used to generate compilations.
-
- * doc/doc.am (doc/groff-man-pages.pdf): Drop `-rU0` option (it's
- unnecessary since we don't yet have PDF hyperlink support in
- this document). Add `-rC1` option to enable continuous page
- numbering.
- (doc/groff-man-pages.utf8.txt): Drop `-rC1 -rU1`. Continuous
- page numbering is superfluous since page numbers are not shown
- in continuous rendering mode. Stop turning on OSC 8 defaults;
- we don't know if the document will be viewed with a supporting
- pager+terminal combination, and further we don't yet have a
- mechanism for making `MR` man page cross references internal to
- the document when they indicate groff man pages.
-
-2022-01-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man pages]: Ship compilations in UTF-8 text and PDF.
-
- Localization support and the resolution of Savannah #61266 have
- made it practical to batch-render all of groff's man pages as a
- single giant document. Provide PDF and UTF-8 text (with ECMA-48
- escape sequences, but not the italic attribute or OSC 8
- sequences).
-
- Reasons for this addition include: {1} it is now possible,
- whereas I don't believe it was in any previous groff release;
- {2} many people still don't realize how much more pleasant
- reading typeset man pages can be (while a subjective assessment,
- I'm not alone[1]); {3} providing these forms permits full-text
- searching of groff's entire man page corpus via the PDF viewer
- or a pager like "less -R", the latter without sacrificing the
- style variations of the text that aid the reader to comprehend
- the material; {4} sentimentally, it honors the 50th anniversary
- of the first Unix manual (dated 3 November 1971)
- <https://www.bell-labs.com/usr/dmr/www/1stEdman.html>.
-
- * doc/doc.am (PROCESSEDDOCFILES): Add
- 'doc/groff-man-pages.{pdf,utf8.txt}'.
- (GROFF_MAN_PAGES{1,2,3}): Add new macro storing names of all man
- pages generated in the build tree. Motivate the reason for 3
- variables in a comment (it's due to groff locale switching).
- (GROFF_MAN_PAGES_ALL): Add convenience macro for use in
- dependency lists required by...
- ('doc/groff-man-pages.{pdf,utf8.txt}'): ...these targets.
- Generate pages with the lint dial turned all the way up.
-
- Fixes <https://savannah.gnu.org/bugs/?61900>.

-
- [man]: Commit c64fd60dff was not quite cooked. The localized
- strings (in English) for the manual section titles need to be
- set at every document load (i.e., when `TH` is called), but only
- if the groff locale is "english". When switching locales, these
- strings were getting "stuck" in their non-English translations
- even when returning to an English page.
-
- * tmac/an.tmac (an*localize): New macro initializes strings.
- (TH): Call `an*localize` if the locale is "english".
- (initialization): Drop initialization of section title strings.

-
- [pdfpic]: Refactor.
-
- Now that the package does not abort upon the first whiff of any
- trouble, avoid littering groff's name spaces. Take this
- opportunity to rename registers and strings to have obvious
- meaning to even the casual reader.
-
- * tmac/pdfpic.tmac: Do it.
- (pdfpic@cleanup): New macro removes temporary strings and
- registers.
- (PDFPIC): Call the cleanup macro upon entry; this way, if we
- errored out from a previous call, we avoid confusion. (We don't
- clean up upon an error return because the leftover objects might
- be useful for troubleshooting.) Rename registers and strings,
- to get them under name space discipline and also to better
- suggest their purpose.
- - convert-pdf -> pdfpic*do-conversion
- - pdf-offset-mode -> pdfpic*offset-mode
- - pspic-args -> pdfpic*pspic-args
- - pdf-offset -> pdfpic*indentation
- - is-pdf -> pdfpic*file-extension
- - img-file -> pdfpic*file-name
- - pdf-wid -> pdfpic*width
- - pdf-ht -> pdfpic*height
- - pdf-deswid -> pdfpic*desired-width
- - pdf-desht -> pdfpic*desired-height
- Call cleanup macro before returning upon successful operation.
-
-2022-01-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [pdfpic]: Improve robustness.
-
- * tmac/pdfpic.tmac (@abort): Rename to `pdfpic@error`. This is
- an auxiliary package, and something else could very well step on
- the former name (or worse, we break it if we're loaded later).
- (pdfpic@error): Stop aborting; simply report an error. It's up
- to the user how serious `PDFPIC` macro problems are. As noted
- in a comment, the user can easily `am pdfpic@error` to tack an
- `ab` request onto the end of its definition. Always report
- input file name and line number. Replace "[PDFPIC]" prefix with
- the name of the macro file complaining, to make it easier for
- groff non-experts to find.
- (PDFPIC): Return upon errors. Recast diagnostic messages. Stop
- implying that we perform any sort of probing test of file type
- {there's no telling what pdfinfo(1) will say}. Apply new
- 'stringdown' request so that we accept '.pdf' file name
- extension in any lettercase. Test file argument for existence
- before proceeding (acknowledge TOCTTOU exposure). Skip file if
- pipeline returned a non-zero exit status or the registers into
- which we extract the height and width are undefined (indicating
- failure of a temporary file to be created or read). Reject
- files with non-positive image width or height reported by
- pdfinfo. Validate `width` and `height` arguments, if given,
- rejecting non-positive values.

- [tbl]: Fix incorrect line numbers in diagnostics. Line numbers
- for multiple format-time diagnostics emitted by tbl(1)-generated
- groff input were off by +5 lines.
-
- * src/preproc/tbl/table.cpp: Fix it.
- (NOP_NAME): Add new preprocessor symbol to construct name of
- "nop" macro to be used as end macro for `ig` requests inside
- macro definitions.
- (table::init_output, table::compute_expand_list,
- table::compute_separation_factor):
- - Move `entry_list->set_location()` calls to more auspicious
- locations.
- - Replace "around line X" language in diagnostic messages with a
- more idiomatic, and less embarrassing, simple report of an
- integer.
- (table::init_output):
- - Add `entry_list->set_location()` call right before emitting
- diagnostic about a table row not fitting on a page.
- - Turn off eqn(1) delimiters when emitting diagnostic about a
- boxed table not fitting on a page (necessitating `.TS H`
- support), using new NOP_NAME-based end macro to achieve this
- inside a macro definition.
- (table::compute_expand_list): Suppress issue of too-wide table
- diagnostic when the `EXPAND` table flag is set (corresponding to
- the `expand` region option), because other code already emits
- diagnostics in this case.
-
- Fixes <https://savannah.gnu.org/bugs/?60598>. Problem appears

-
- Ensure that the various format-time diagnostics that a
- tbl-preprocessed document can generate (1) occur when they are
- supposed to and (2) are appropriately suppressed by the
- "nowarn" and/or "nokeep" region options. One of them is an

- [tbl]: Fix Savannah #61854.
-
- * src/preproc/tbl/table.cpp (compute_expand_width): To properly
- warn if a table is too wide to fit between the indentation and
- the right margin, we need to compute its column widths including
- those eligible for expansion via the 'x' column modifier; we
- cannot use the same expression that we do to determine the
- amount of space we have to distribute among the expanded
- columns. Iterate through columns again (the function was
- already doing so twice), once to potentially produce the
- warning, and then as before to distribute any available width.
- In other words, warnings were only being emitted for too-wide
- tables where one or more columns used the 'x' modifier.

- [font,tmac]: Simplify Unicode character mapping process.
-
- * tmac/unicode.tmac: Drop. It was originally added in 2005 to
- suppress horizontal spacing of glyphs in the range U+0483..9.
- Its purpose has wandered over the years; most recently to map
- the Basic Latin ("ASCII") hyphen-minus, apostrophe, and grave
- accent to special characters (and thus ultimately to the General
- Punctuation block). But this is unnecessary since the font
- descriptions for devices with the `unicode` property can provide
- this information, and anyone who wants to alter the mappings can
- change either font description files, output device macro files,
- or troffrc; or add `char` requests to their macro packages or
- documents (in decreasing magnitude of ambition).
-
- * tmac/html.tmac:
- * tmac/tty.tmac: Stop sourcing unicode.tmac.
-
- * tmac/tmac.am (TMACNORMALFILES): Stop shipping it.
-
- * font/devutf8/NOTES: Drop remarks about mapping of \[a~],
- \[a^], and Basic Latin circumflex accent and tilde. Not only do
- I disagree with the reasoning (whether these glyphs are "too
- small" depends on the font used by the terminal emulator, over
- which we have no control), but this mapping happens in a
- completely different part of the source tree,
- src/libs/libgroff/glyphuni.cpp.
-
- * font/devhtml/R.proto:
- * font/devutf8/R.proto: Add mappings for the five Basic Latin
- characters that map surprisingly (see groff_char(7)) and are not
- syntactically significant to troff. Three of these are ported
- from unicode.tmac.
- (html): Don't migrate the hyphen-minus--yet.
-
-2022-01-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/tty-char.tmac: Drop redundant logic. We don't need to
- source the `cp1047` or `latin1` files here; `troffrc` will
- already have loaded `tty` for us, which loads whichever applies.
-
-2022-01-14 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Separate concerns better; stop re-generating plain
- text and HTML documents when the 'doc' target is updated; these
- are already handled by the 'build_infodoc' target.
- (build_infodoc): Use existing phony targets for plain text and
- HTML output files instead of repeating filename literals.
- (doc_all): Remove those same two phony targets from this one's
- dependencies.
-
-2022-01-14 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp: Rename `eoi_macro_name` to
- `end_of_input_macro_name`. It's long, yes, but better parallels
- `blank_line_macro_name` and `leading_spaces_macro_name`. It is
- not used in lengthy expressions and furthermore clarifies the
- meaning of the nearby function name `eoi_macro` in one use.
-

- [docs]: Be more careful with control characters when they are
- word-initial in filled text lines. The idea is to prevent
- baffling surprises if a sentence is recast in a text editor, and
- a word beginning with a dot or neutral apostrophe is reflowed
- onto the beginning of the next input line--suddenly it is parsed
- as a control character. Based on a patch by Bjarni Ingi
- Gislason.

-
- [tmac]: Manage hyphenation mode more carefully in localization
- packages.
-
- * tmac/{cs,de,it,sv}.tmac: Localize the man(7) package's HY
- register.
-
- * tmac/{cs,de,fr,it,sv}.tmac: When localizing the ms(7) package,
- use mode "2" instead of "3": the 'hy' request complains of
- contradictory hyphenation modes if "3" is used (the semantics of
- the hyphenation mode are complex and non-orthogonal; see
- groff(7) or our Texinfo manual).
-
- * tmac/{cs,de,en,fr,it,sv}.tmac: If the one language-independent
- hyphenation bit (don't hyphenate just prior to a page location
- trap) is set, preserve it; this way a system's troffrc or a
- macro package can set it and it will not get turned off by the
- localization package, which for best results should be loaded
- after any full-service package (and any auxiliary package
- requiring localized strings, though none are yet distributed
- with groff).
-
-2022-01-06 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tmac]: Add unit test for localization macro files. Right now

-
- [indxbib]: Document --version in usage message.
-
- * src/utils/indxbib/indxbib.cpp (usage): Document --version
- option. Use more informative metasyntactic variable names.
- Organize usage message consistently with our others, and stop
- wrapping the output lines: we know neither the width of the
- terminal nor the length of the `program_name` string we're
- interpolating. See commit b4de44f0, 19 July 2021.

-
- [libbib]: Refactor index header checking.
-
- * src/libs/libbib/index.cpp: Move more header validity checks...
- (index_search_item::load): ...from here...
-
- (index_search_item::check_header): ...to here. Test all size
- values in header for negative values (never valid) before
- proceeding. (These data could be changed to unsigned integer
- types in the file format, but that would require bumping the
- file version. That in turn would make indexes generated with
- groff 1.23 unusable on systems running older groffs and, perhaps
- worse, would make groff 1.23 reject index files produced by
- older groffs. On the other hand, the regeneration of index
- files should be, for those who use them, a common activity, and
- as long as the original database files are kept intact, it seems
- likely that most people, given modern machines, won't even
- notice a slowdown in document generation when refer(1) and
- friends fail to open the indices and fall back to full-text
- searches of the originals. So we could still consider revising
- the file format before the groff 1.23 release.)
-
- * src/libs/libbib/index.cpp (index_search_item::load):
- Explicitly perform widening conversion from signed `off_t` value
- {from a stat(2) buffer} to an unsigned integer; quietens
- compiler warning about comparison between integers differing in
- signedness.
-
-2022-01-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac (AC_CHECK_HEADERS): Expect stdbool.h, since we
- now use it in src/include/lib.h.
-
-2022-01-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libbib, libgroff, indxbib]: Slightly refactor.
-
- Also, it's silly to test even numbers > 2 for primality. Stop.
-
- * src/include/lib.h: Include `stdbool.h` since this header file
- is used for both C and C++ code.
-
- * src/include/lib.h (is_prime):
- * src/libs/libgroff/prime.cpp (is_prime): Boolify. Return
- Boolean instead of integer literals and demote return type to
- `bool`. Include `assert.h` and add assertion to reject
- mathematically offensive input.
-
- * src/libs/libbib/index.cpp
- (index_search_item::read_common_words_file): Test only odd
- numbers for primality.
- * src/utils/indxbib/indxbib.cpp (main): Same. Since the number
- comes from user input, make it (a potential hash table size) odd
- first.
-
-2022-01-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man]: Internationalize and localize.
-
- * tmac/an.tmac (TH): Indirect predefined manual section titles
- through new strings `an*section[1-9]` so that they can be
- localized.
- (initialization): Give these strings English defaults.
- (TH): Move `ss` request from here...
-
- * tmac/en.tmac: ...to here. It's not the man(7) package's
- business what the inter-word and inter-sentence spacing values
- are. Also, having the correct[disputed] inter-sentence spacing
- value for English in its localization file restores it for the
- benefit of multi-lingual documents (mainly roff applications
- other than man(7)).
-
- * tmac/{cs,de,fr,it,sv}.tmac: Supply translations for the manual
- section titles; these were done by a monoglot American employing
- Google Translate, so those scandalized or running into howlingly
- wrong locutions are warmly invited to submit corrections.
-
- * tmac/trans.tmac: Load localized strings.
-
- Fixes <https://savannah.gnu.org/bugs/?61734>.
-
-2022-01-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/grog.pl: Handle auxiliary macro package
- arguments correctly.
- (process_arguments): Don't append the argument to the '-m'
- option to the command line; requested macro packages have
- dedicated logic.
- (construct_command): When iterating through requested package
- list, assume each element is an auxiliary package unless it
- matches an element in the list of main packages. If the
- assumption holds, append the package name to a new list,
- `auxiliary_package_argument` (prefixed with '-m'). Push this
- list onto the command line after any main package.
-
- Also rename `$selected_main_package` to `$main_package` for
- brevity, and drop unused global lists `m` and
- `supplemental_package`.
-
- Fixes <https://savannah.gnu.org/bugs/?61758>.
-
-2022-01-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/tests/smoke-test.sh: Add test cases for user
- specification of auxiliary macro packages.
-
-2022-01-03 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [me]: Drop unnecessary code. Apart from being superfluous, it
- prevented a user-defined value of the `sx` register from being
- applied to the first footnote marker interpolated, a subtlety
- that escaped my notice because the first footnotes in our
- "meref" and "meintro" documents are not numeric, but symbolic,
- and their markers occurred on lines with vertical space above
- and below. (The bug was further masked by an otherwise
- redundant redefinition of the `*` string inside the `)f` macro.)
-
- * tmac/e.tmac ()f, +c): Stop redefining footnote marker string
- `*` after updating the automatic footnote number; its
- interpolation is already backslash-protected.
- ()d, pd): Stop redefining delayed text marker string `#` for an
- analogous reason.
- (initialization): Drop unneeded `_*` and `_#` strings.
-
- Thanks to Robert Goulding for his feedback and patience. See
- <https://savannah.gnu.org/bugs/?61025>.
-
-2022-01-03 G. Branden Robinson <g.branden.robinson@gmail.com>

-
- [me]: Revise `n1` and `n2` interface and behavior.
-
- There were several bugs in the previous implementation.
-
- * tmac/e.tmac (po): Issue diagnostic if an attempt is made to
- set the page offset to a negative value.
-
- (n1): Accept new optional "C" argument to behave more (but not
- exactly) like roff(1), as the formerly-recognized "c" argument
- to `n2` did. If present, the line length is reduced by the same
- amount (in new interface register `no`) as the line number field
- to preserve the overall line length. Save the previous line
- length in internal register `_l` and set a flag, stored in `?N`,
- indicating this reduction. Otherwise, the macro expects to be
- able to reduce the page offset to accommodate the line number.
- If it cannot (for example, with the zero page offset default
- used by nroff output devices), see above re: the `po` macro.
-
- (n2): Cache the last line number that may have been output,
- instead of the current one, so that we can operate on it
- consistently with user expectations. Do this earlier, and
- rename this macro-local variable from `_ln` to `_n` so that we
- don't need groff's `do` request to operate on it. Drop
- recognition of "c" as an optional second argument. If turning
- off line numbering: if the line length was shortened (`?N`)
- restore the saved value and delete `_l` register; otherwise,
- reverse the change to the page offset. Delete `_n` register.
-
- (initialization): Assign `\w'0000'u` to `no` register; this was
- previously hard-coded in `n1` and `n2`. Initialize `?N` with 0.
-
- * doc/meref.me.in (roff Support): Update to reflect interface
- changes and describe behavior more accurately.
-
- * doc/meref.me.in (Summary):
- * tmac/groff_me.7.in (Registers): Document new `no` register and
- mark it as a groff extension.
-
- * NEWS: Add item documenting interface changes.
-
- Fixes <https://savannah.gnu.org/bugs/?61646>. See the comments
- in the report for a lengthy enumeration of rendering problems

-
- * tmac/e.tmac: Fix code style nits.
- - Use new terminology in diagnostic. See commit 66ac1a8db9,
- 11 December.
- - Drop unused '&&&' annotation for macro definitions. This
- was a BSD me(7) implementation detail wherein parts of the
- package were broken out into module files, loaded if/when
- their macros were called. groff me(7) is monolithic, except
- for devtag and refer(1) support.
- - Remove '&&' end macro when we're done using it.
-
-2021-12-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [me]: (Re-)localize strings.
-
- * tmac/{cs,de,fr,it,sv}.tmac: Update package localizations to
- use new resources. As a happy side effect (and with the new
- appendix string), the `+c` macro is now localized for Czech,
- German, and Swedish.
-
- * doc/meintro_fr.me.in (Les Parties du Document): Update example

-
-2021-12-27 G. Branden Robinson <g.branden.robinson@gmail.com>

-
- * tmac/e.tmac (initialization): Introduce internal
- `_mo1`..`_mo12`, `_dw1`..`_dw7`, and `_td_format` strings (with
- English defaults). Define them outside of the new `ld` macro so
- that they can be overridden by localization packages.
- (ld) <dw, mo, td>: Populate via the above new strings.
- * tmac/trans.tmac: Stop defining `mo` and `dw`. Instead, make
- them aliases of the new strings above. Handle `wa` and `wc`
- similarly.
-
-2021-12-26 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [me]: Add `ld` macro to re-init date/l10n stuff.

-
-2021-12-26 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/e.tmac: Ease localization and customization by exposing
- strings for "Chapter" and "Appendix" instead of hard-coding
- these words into the `$c` macro.
- (initialization): Define new `wa` and `wc` strings. Separate
- these and existing localization strings from `y2` and `y4`
- initialization since the latter don't involve natural languages.
- ($c): Interpolate these strings in chapter and appendix headings
- and in calls to `$C` hook macro. Set "Chapter" and "Appendix"
- in mixed case instead of full capitals, and set one
- adjustable nonbreaking word space `\~` between them and the
- chapter number instead of two unadjustable nonbreaking spaces.
- {These changes do slightly alter the default output of the
- package when the `+c` macro is used.}
-
- * doc/meref.me.in (Predefined Strings):

-
-2021-12-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/e.tmac: Fix groff warnings and correctness issue.
- (n2): Prefix `ie` request with `do` because it uses the groff
- `\B` escape sequence. Use braces to group multiple requests
- after an `el` request: `ie` and `el` count as two requests, not
- one. Add comment regarding the unfortunate choice of brace
- style given *roff's syntactical constraints.
- (n2, (c): Conceal bare tab in request argument list (exposed by
- no longer stripping the macro file).

-
- * tmac/e.tmac: Slightly refactor footnote numbering.
- ()f): Tighten code style and end string definition with comment.
- (+c, initialization): Drop unused auto-incrementation of

-
- Generate me(7) manual sources as part of the build. We had been
- shipping 'me' sources with the string '@VERSION@' in them and
- only sed-replacing that to produce generated PostScript, but
- this replacement was not occurring for users who processed the
- documents themselves.
-
- * doc/meintro.me:
- * doc/meintro_fr.me:
- * doc/meref.me: Rename these to...
- * doc/meintro.me.in:

-
- * tmac/e.tmac: Add nroff mode string definitions for 4.4BSD

- [troff]: Remove `DEBUGGING` preprocessor cruft.
-
- * src/roff/troff/input.cpp:
- * src/roff/troff/mtsm.cpp: Stop defining `DEBUGGING`
- preprocessor macro (as empty).
-
- * src/roff/troff/input.cpp: Give `DEBUG_OPTION` an empty string
- value if the former is undefined, so the `getopt_long()` call
- will compile.

-2021-11-26 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Slightly refactor table format column modifier `p` and
- `v` validation.
-
- * src/preproc/tbl/main.cpp (process_format): Make code terser by
- introducing references to `list->point_size` and
- `list->vertical_spacing`. Doing this requires a new scope
- {because a switch case isn't one} so add it, without updating
- indentation for this commit. When complaining of out-of-range
- type size or vertical spacing, report the limit.
-
-2021-11-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Improve diagnostic messages.
-
- Revise diagnostic messages generally to use terminology
- consistent with the recent rewrite of tbl(1), identify a
- contextual token when possible, and communicate more helpfully.
-
- * src/preproc/tbl/main.cpp (process_options): Tell the user
- which region option is missing a closing parenthesis or cannot
- accept an empty argument. Refer to region options as such, not
- simply "options" (so they can't be confused with command-line
- options). Say that input is "invalid" instead of "bad".
- (process_format): Say "table format specification" instead of
- just "format". Say "column classifier" instead of "format".
- When a column modifier is missing an argument or a closing
- parenthesis, identify it and refer to it as a "column modifier"
- instead of omitting context. Inform user that arguments to `p`
- and `v` column modifiers must be "(optionally signed) integer"s,
- not "numbers", lower these diagnostics' levels from error to
- warning, and indicate that the modifier is ignored. Clarify
- diagnostic when extra characters trail `.` at the end of a table
- format line.
- (process_data): Say "table entry" instead of "data entry" when
- discarding an excess one.
- (process_table): Say we're giving up on "this table region", not
- this "table", particularly since any table continuations (.T&)
- are ignored.
-
-2021-11-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Fix call to `getopt_long()`.
-
- * src/preproc/tbl/main.cpp (main): Stop telling `getopt_long()`
- to look for a `T` option. Continues b4bbf32e, 16 October 2020.
-
-2021-11-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Tweak usage message.
-
- * src/preproc/tbl/main.cpp (usage): Document `--version`. Give
- version retrieval mode separate synopsis. Use more normative
- synopsis syntax.
-
-2021-11-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Fix code style nits.
-
- * src/preproc/tbl/main.cpp (process_input_file)
- (entry_format::debug_print, process_data, main): Replace
- `assert(0)` calls with communicative predicates.
- (struct input_entry_format, input_entry_format::debug_print,
- process_format): Boolify. Demote and rename `int`s
- `last_column` and `equal` to `bool`s named `is_last_column` and
- `is_equal_width`. Assign them Boolean literals.
- (process_format): Boolify. Demote `have_expand`, `got_format`,
- and `got_period` from `int` to `bool`. Use Boolean literals in
- assignments thereto.
- (process_options): Swap order of null pointer comparison when a
- typo or thinko could lead to lvalue assignment.
- (process_data): Boolify. Demote `give_up` from `int` to `bool`.
- Demote and rename `int` `row_comment` to `bool`
- `seen_row_comment`. Use Boolean literals in assignments
- thereto.
- (main): Use standard C library symbols `EXIT_SUCCESS` and
- `EXIT_FAILURE` with `exit()` calls instead of `0` and `1`.

-
- [grog]: Fix Savannah #61520.
-
- * src/utils/grog/grog.pl: Move hash `preprocessor_for_macro` to
- global scope since it is now mutable across `do_line` subroutine
- calls.
- (do_line): Adjust regex matching an end macro to work better.
- Check names of macros being defined by the document; if they
- start with '[' or ']', stop attempting to detect refer(1) usage,
- by deleting its key from the `preprocessor_for_macro` hash.
-
- Fixes <https://savannah.gnu.org/bugs/?61520>.

-
- * doc/groff.texi (Page Motions):
- * man/groff.7.man (Escape short reference): Fix error: the `\r`,
- `\u`, and `\d` escape sequences move in ems, not vees, despite
- being vertical motions. Add discussion and example. Thanks to
- Bjarni Ingi Gislason for pointing out the problem in groff(7)
- and Tadziu Hoffman for his lucid explanation.
-
- Fixes <https://savannah.gnu.org/bugs/?61437>. Thanks to Bjarni
- Ingi Gislason for the report and a suggested patch.
-
-2021-11-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/include/error.h: Drop `extern` storage class from
- diagnostic function prototypes. Drop parameter names from
- prototypes, in keeping with the Stroustrup-style C++ used in
- most of groff.
-
-2021-11-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libgroff/font.cpp (font::load): Update diagnostic
- messages to say "kerning pair" instead of "kern pair".
-
-2021-11-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (read_size): Update diagnostic
- messages to use more normative language: say "type size" instead
- of "point-size", and "escape sequence" instead of "escape".
- * src/roff/groff/tests/\
- use_point_size_escape_with_single_digit_arg.sh: Update expected
- diagnostic wording in text.
-
-2021-11-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (read_size): Boolify. Update
- prototype. Demote return type from `int` to `bool`. Use
- Boolean literals for return values. Similarly demote local
- variable, rename it from `bad_digit` to
- `contains_invalid_digit`, and use Boolean literals with it.

-2021-11-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: If "nowarn", suppress table row warning.
-
- * src/preproc/tbl/table.cpp (table::init_output): Bracket the
- generated groff code that emits a warning if a table row
- overruns a page location trap (usually, is too long to
- vertically fit on the page) in a test for whether the "nowarn"
- region option was given, so that this warning is suppressed as
- well when that option is used.
- * src/preproc/tbl/tbl.1.man (Region options): Document new
- "nowarn" behavior.
-
- {"nokeep" also suppresses this warning, for a different reason;
- no diversion is created to hold the table row, so its vertical
- size does not exist to be compared to the distance to the next
- page trap.}
-
- Fixes <https://savannah.gnu.org/bugs/?61477>.
-
-2021-11-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/tbl/table.cpp (table::do_vspan): Fix code style
- nits. Swap order of null pointer and zero equality comparisons
- when a typo or thinko could lead to lvalue assignment. Break a
- series of 6 and-ed assertion predicates into separate `assert()`
- calls--sure to be less maddening for anyone who has to debug
- such a contingency. Clarify comment since C++98 didn't yet have
- `nullptr`.
-
-2021-11-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [m4]: Clean up shell variable quoting and bracing.
-
- * m4/groff.m4 (GROFF_PROG_YACC, GROFF_MAKEINFO)
- (GROFF_BROKEN_SPOOLER_FLAGS, GROFF_TARGET_PATH_SEPARATOR): Stop
- bracing shell variable expansions that don't require it; the
- shell is not make(1).
- (GROFF_PROG_YACC, GROFF_MAKEINFO): Double-quote shell variable
- expansions that might produce whitespace.
- (GROFF_MAKEINFO): Drop unnecessary leading zeroes from version
- number component construction. Drop unnecessary escaping of
- plus sign in expr(1) input.
-
-2021-11-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [m4]: Clean up test(1) usage.
-
- Get rid of string (non-)nullity tests and comparisons involving
- concatenation with garbage (usually "x"). Even the GNU Autoconf
- manual's shell portability material doesn't recommend this. It
- must be either a bodge cooked up by shell programmers who
- couldn't remember to quote variable expansions, or a workaround
- for shells of such poor quality that they defied the odds and
- decayed out of usage or got fixed.
-
- Instead, use double quotes (only where necessary). Test for
- non-empty strings with "test -n" and empty strings with "test
- -z". Stop quoting literal comparands that obviously have no
- shell metacharacters in them.
-
- * m4/groff.m4 (GROFF_PRINT, GROFF_PROG_YACC, GROFF_PERL)
- (GROFF_DOC_CHECK, GROFF_MAKEINFO, GROFF_TEXI2DVI)

- (GROFF_HAVE_TEST_EF_OPTION, GROFF_BASH, GROFF_UCHARDET)

- (GROFF_USE_GROFF_ALLOCATOR): Do it.
-
-2021-11-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_TEXI2DVI): Add dependency on
- `GROFF_MAKEINFO` macro. Rewrite to also test `MAKEINFO`
- variable, which is empty if the `makeinfo` command is not
- installed or too old. Consequently ignore `texi2dvi` if is too
- old without having to do a version check (since it and
- `makeinfo` are distributed together, both being part of GNU
- Texinfo).
-
- * doc/doc.am (.texi.dvi, .texi.pdf): Update error message to
- indicate that `texi2dvi` is _either_ missing or too old.
-
-2021-11-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_MAKEINFO): Stop throwing a warning if the
- installed `makeinfo` is old but the distributed Info manual is
- up to date. This is not a configure-time problem; the user will
- be notified when they run 'make' if they modify doc/groff.texi,
- or if they run 'make doc' (which has required a TeX installation
- for years). Empty the `MAKEINFO` variable immediately if a
- too-old version is detected. Drop needless `AC_SUBST`itution of
- the detected `makeinfo` version.
-
-2021-11-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_HTML_PROGRAMS): Clarify message; it is only
- groff-generated HTML that is disabled by the absence of the
- programs checked for. (`makeinfo` can still generate our
- Texinfo manual in HTML format.)
-
-2021-11-11 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Drop `BUILD_INFODOC` symbol. Ship manual in GNU Info,
- text, and HTML forms in distribution archive.
-
- * Makefile.am (MAINTAINERCLEANFILES): Initialize.
- (MOSTLYCLEANADD): Drop unused variable.
- * configure.ac: Drop `AM_CONDITIONAL([BUILD_INFODOC]...`.
- * doc/doc.am (EXTRA_DIST): Rearrange shipment of our Texinfo
- manual source files to precede all of the generated forms, for
- clarity. Drop all `BUILD_INFODOC` conditionals. Make
- `build_infodoc` phony target depend on plain text, GNU Info, and
- HTML forms of Texinfo manual unconditionally. Also drop unused
- variables `groffinfodir`, `groffpdfdir`, and `texi2dvi_missing`.
- (EXTRA_DIST, MAINTAINERCLEANFILES): Add Info form of manual.
- Drop glob pattern attempting to match the segments that
- `makeinfo` breaks it into. It isn't necessary for
- MAINTAINERCLEANFILES.
- (EXTRA_DIST, MAINTAINERCLEANFILES): Add text form of manual.
- (EXTRA_DIST, MAINTAINERCLEANFILES): Add HTML form of manual.
- (dist-hook): Depend on new (phony) target `dist-info-bits`.
- (dist-info-bits): Look for the info document in the build
- directory, then the source directory. (It could be in either
- place depending on whether the build from a Git working tree is
- being done in or out of a separate build directory.) When
- found, copy the segments to the assembly area for the
- distribution archive.
- (install_infodoc): Refactor. Remove any groff info files from
- the destination info directory using a shell glob directly
- instead of a partly redundant ls(1) command substitution.
- Similarly, use a shell glob to cp(1) the info files (including
- any matched segments) to the destination info directory before
- running `install-info`. (In this process I learned that
- `install-info` doesn't "install" anything; instead, it
- {de-}registers info files with their top-level catalog.)
-
-2021-11-11 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (.texi.txt, .texi.html): Reorder pattern rules to
- make it clearer which formats require only `makeinfo` and which
- require `texi2dvi`. The latter imposes more build dependencies,
- including a full TeX installation.
-
-2021-11-11 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [mom]: Build more quietly.
-
- * contrib/mom/mom.am (penguin.{ps,.pdf}): Make targets quiet by

-
- [tests]: Revise a test's setup.
-
- * src/roff/groff/tests/fp_should_not_traverse_directories.sh:

- by Automake's "distcheck" target.
-
-2021-11-10 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Accept `\&` as an empty table entry.
-
- * src/preproc/tbl/table.cpp (table::add_entry): Suppress

-
-2021-11-10 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tbl]: Update diagnostic messages.
-
- * src/preproc/tbl/main.cpp (process_options, process_format):

-
-2021-11-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff,grops]: Slightly refactor.
-
- * src/devices/grops/ps.cpp: Explicitly preprocessor-include
- "lib.h" since we use the `PI` symbol it defines.
-
- * src/include/lib.h: Add inclusion guard. Wrap only `extern "C"
- and its braces in preprocessor conditionals, so that prototypes
- are present in the header even for C language code that
- #includes this header. Add `static` storage class to `PI`

-
- * tmac/an.tmac (OP): Fix code style nits. Don't quote macro

- groff font escape sequence syntax. Use adjustable non-breaking
- space escape sequence instead of a non-adjustable one.
- Parenthesize numeric expression for better readability.

- [libgroff]: Make allocator replacement optional. Switch it
- off by default, relying on C++ runtime new/delete support.
-
- * configure.ac: Call new `GROFF_USE_GROFF_ALLOCATOR` m4 macro.
- Use `AM_CONDITIONAL` to set Automake variable
- `USE_GROFF_ALLOCATOR` if appropriate. Report whether the
- allocator is used in configure script output summary.
- * m4/groff.m4 (GROFF_USE_GROFF_ALLOCATOR): Define new macro to

- hanging.
-
-2021-11-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (GROFF_TMAC): Use separate shell variable for
- `AC_MSG_RESULT()` content since the human-readable string we

- `AC_SUBST()`-itution. Problem introduced by me in commit
- 19670348, 31 October.

-
- * tmac/tmac.am (MOSTLYCLEANFILES): Remove `$(TMACMDOCFILES)`.
- This variable, formerly named `TMACMDOCSTRIPFILES`, should not

-
- * src/libs/libgroff/error.cpp (do_error_with_file_and_line):
- Revise to eliminate `fprintf()` calls, which might perform
- dynamic memory allocation, rendering this function unsafe to
- call after memory allocation failures. Since this function is
- near the top of our diagnostic output call stack, that would be
- unfortunate. `errprint()` does not use dynamic allocation, nor
- do the `i_to_a()` and `ui_to_a()` functions it calls to format
- integers.
-
-2021-11-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * configure.ac: Add `strdup` to AC_CHECK_FUNCS since we are
- using it and the whole point of libgroff's `strsave()` was to
- get along without it. But `strdup` has been standardized in
- POSIX for 20 years (SUSv3, POSIX:2001) and is on its way into
- ISO standard C (N2353) and C++ (P2391R0) as well.

-
- * src/libs/libgroff/fontfile.cpp (font::open_file): Don't open

- traverse directories outside the configured font path. Also
- refuse to open the file if the `sprintf()` used to construct its
- file name doesn't write the expected quantity of bytes to the

- {in groff man, this occurs only when collecting a `TP` paragraph
- tag}, then typeset the URI as part of the indented paragraph.
- (UE, ME): Pop the diversion and environment stacks only if we

- if there were any.

-
- * tmac/s.tmac (DS): Drop a redundant unconditional break; every
- display macro we call in the event of a valid call already
- breaks the line, and it's polite to not break if we're given an

-
- * src/preproc/tbl/table.cpp (table::add_entry): If we see a '\^'
- entry on the first row of a table, it's invalid, but we need to
- create an empty entry in its place. Otherwise, someone can put
- another '\^' right below the one on the first row, creating a
- reference to a nonexistent table entry and provoking a SEGV.
- Issue an error diagnostic (distinct from the one in
- `do_vspan()`), create the entry, and skip `do_vspan()` (given a
- '^' in a first-row definition, it issues an error diagnostic and
- returns early, which suffices). Problem appears to date back to
- groff 1.02 (June 1991) at the latest.

-
- * tmac/an-ext.tmac (UE, ME): Stop adding the page offset `.o`
- when performing the available horizontal space computation for
- the typeset URI string. This made no difference on nroff
- devices (grotty; even with `.po 15n`), but it caused the
- breaking decision to be too conservative on troff devices
- {grops}, forcing some URIs that would fit on the current line to
- the next one.

- [libgroff]: Do more device and font description file validation,
- resolve an assertion failure arising from a negative declared
- device resolution, and correct a documentation error.
-
- * src/libs/libgroff/font.cpp (font::load): Include more
- information about invalid input in diagnostic messages.
- - When a kern pair's amount is missing or invalid, report the
- name of the kern pair.
- - When someone tries to declare the first entry in the charset
- section as an alias, report the glyph name.
- - Identify the token for the unnamed character if an attempt
- is made to alias it.
- - When an out-of-range character type is applied to a glyph,
- name the glyph.
- (font::load_desc): Same.
- - Drop redundant zero initialization of `res`.
- - Check all directives that take basic units for positive
- values, adding `res`, `unitwidth`, `paperwidth`, and
- `paperlength`. Update this diagnostic to demand positive,
- not nonnegative, values.
- - When the font count is long in a `fonts` directive, report
- how many font names were declared (and thus expected). (If
- the count is short, the next line is read for a font name,
- like 'tcommand' in our devutf8/DESC.)
- - When interpreting a `papersize` directive, throw an error
- and return false if `res` has not yet been encountered,
- since it is used in subsequent computations.
- - When a paper format cannot be determined, report the
- original declared value from the DESC file. Use `strdup()`
- to save it since it gets clobbered by the resolving process.
- `free()` the saved string when we're done, regardless of
- error condition.
-
- * doc/groff.texi (Device and Font Files):
- * man/groff_font.5.man (DESC file format): Document additional
- exception to order-indifference of directives: (at least one)

-
- * tmac/mdoc/doc-nroff (doc-setup-page-layout): Set the title
- length to the device line length (register `.l`) if register
- `LT` is not defined. This keeps the title length from being set
- to 78n when the line length is not, preventing the output from
- looking silly.
-

- `sub->glyphs`; the latter is a member array of a `subencoding`
- struct so it can't be a null pointer. (`glyphs` is an array of
- pointers to `const char`; the _elements_ of the array can [and

- [troff]: Handle special character escape sequences that map to
- basic Latin glyphs in device control escape sequences
- consistently among output devices.
-
- * src/roff/troff/input.cpp (encode_char): Rearrange
- conditionals. This is the logic that puts the "whatever" within
- a \X'whatever' escape sequence into GNU troff's intermediate
- output. Handle adjustable and nonadjustable space escape
- sequences ("\~" and \ ") first. Then, if the token is a special
- character escape sequence, retrieve its "contents" (glyph name).
- Move the basic Latin mapping for the seven glyph names '-',
- 'aq', 'dq', 'ga', 'ha', 'rs', and 'ti' here, before checking
- whether the device description issued the
- 'use_charnames_in_special' directive. This way, the 'html' and
- 'xhtml' output devices can straightforwardly embed these basic
- Latin characters in device control escapes (notably, "html:",
- for which the present convention is to follow the this tag
- immediately with a literal HTML URI, complete with `<a href>`
- element syntax). If the special character is none of these and
- we should 'use_charnames_in_special', proceed as groff 1.22.4
- and earlier did. This is a behavior change, as was my addition
- of this translation mechanism in the first place, so...

- [tests]: Improve portability.
-
- * src/devices/grotty/tests/osc8_works.sh: Fix typo in test.
- Multiple regex quantifiers after an atom were not flagged with a
- diagnostic by GNU grep 3.3, but were by BSD grep 2.5.1-FreeBSD.
-
- * src/roff/groff/tests/smoke-test_html_device.sh: Stop trying to
- set $LC_CTYPE to "C.UTF-8"; some systems don't support this
- expediency. Skip the test if the tester hasn't configured the
- environment adequately.
-
- * tmac/tests/s_TC-works-with-percent-in-custom-titles.sh: Fix
- portability problems exposed by FreeBSD sed (which version is
- unclear). {1} Use POSIX BREs, dropping use of '+' quantifier.
- {2} Add semicolons to terminate commands before braces on the
- same line. Simplify surrounding test structure.
- * tmac/tests/e_footnotes-work-with-columns.sh: Fix same two sed
- problems.
- * tmac/tests/andoc_flush-between-packages.sh:
- * tmac/tests/doc_accept-mixed-case-section-headings.sh:
- * tmac/tests/an_TS-do-not-keep-tables-when-cR-set.sh: Fix same

-
- * src/roff/groff/tests/on_latin1_device_oq_is_0x27.sh: Rewrite
- test to stop using a here document (containing an unpaired
- single quote) inside a command substitution, which is broken in
- GNU Bash 3.2 and some other versions. Instead construct the
- input with printf(1). Also gets rid of a Bashism (process
- substitution) that Ingo pointed out years ago.
- * src/utils/grog/tests/recognize-perl-pod.sh: Same problem,

- construct programmatically, so move it into an external file...
- * src/utils/grog/tests/foo.man: ...here.

-2021-10-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Make sed-based insertion of `lf` requests more

- a sed expression inside a shell command executed as part of a
- Make target rule. We assume that neither the POSIX shell $''
- operator nor a working printf(1) is available.
- (DOC_GROFF): Define a shell variable containing a literal
- newline, evading make(1) and echo(1)'s valiant attempts to
- consume it.
- (doc/pic.html, doc/webpage.html): Repeat trick, slightly

- [groff]: Fix code style nits.
-
- * src/roff/groff/groff.cpp (main, help): Use standard C library
- preprocessor symbols `EXIT_SUCCESS` and `EXIT_FAILURE` instead
- of 0 and 1 literals, respectively. See commit fa4c27e9, 7
- September.
- (main): Replace `assert(0)` with a communicative predicate.

-
- * src/roff/troff/troff.am: Build more robustly.
- (src/roff/troff/majorminor.cpp): Drop progress-reporting `echo`
- in favor of prefixing final rule command with `$(AM_V_GEN)`.
- Prefix earlier rule commands with `$(AM_V_at)`. Use `printf`
- instead of `echo` to build the file, and create a temporary file
- at first so that we don't race with the compiler on parallelized
- builds.
-

-
- * src/preproc/eqn/eqn.am (neqn): Simplify: drop removal of
- target prior to overwriting it; any system we can build groff on
- should have a shell that implements the clobbering semantics of
- the POSIX shell '>' operator. (If this isn't true, we have
- _many_ other target rules in our build to which we must add
- prefatory `$(RM)`s, or I miss my guess.)

- * src/libs/libgroff/libgroff.am: Build more quietly and

- (src/libs/libgroff/version.cpp): Drop progress-reporting `echo`
- in favor of prefixing final rule command with `$(AM_V_GEN)`.
- Prefix earlier rule commands with `$(AM_V_at)`. Use `printf`
- instead of `echo` to build the file, and create a temporary file
- at first so that we don't race with the compiler on parallelized
- builds. Drop nilpotent sed transformation; this looks like a
- relic of past times when we'd drop a trailing ".0" from the
- version number stored in the C symbol `Version_string`.
- (charset.alias, ref-del.sed, ref-add.sed): Prefix rule command

-
- * font/devpdf/devpdf.am: Build more quietly.
- (font/devpdf/enc/text.enc, font/devpdf/map/symbolmap,
- $(DEVPDFFONTMAP_1)): Prefix all rule commands with
- `$(AM_V_at)`; since these are all `mkdir`s and `cp`s, I reason
- that little can go wrong with them that won't be disclosed by
- these tools' own diagnostic messages, so they are insignificant
- from a perspective of build progress.
-

-
- * doc/doc.am: Build more quietly.
- (doc/examples.stamp): Prefix all rule commands with
- `$(AM_V_at)`; since this target is a stamp file instead of
- a useful artifact to be distributed, make its creation
- completely silent by default.
- (doc/groff.info, .texi.txt): Prefix directory creation with
- `$(AM_V_at)` and `makeinfo` command with `$(AM_V_GEN)`.
- (.texi.dvi, .texi.pdf): Prefix directory creation with
- `$(AM_V_at)` and `makeinfo` command with `$(AM_V_GEN)`. Send
- diagnostic message to standard error if `texi2dvi` is
- unavailable.
- (.texi.html): Prefix directory creation with
- `$(AM_V_at)`. Two HTML versions are produced, in split and
- unsplit versions; prefix one `makeinfo` command with
- `$(AM_V_GEN)` and the other with `$(AM_V_at)` so that only one
- message is produced.
- (gnu.eps): Drop useless/noisy `echo` command. Prefix copy
- operation with `$(AM_V_at)`. Send diagnostic messages to
- standard error if there are problems with the Netpbm tools.
-
- (MOSTLYCLEANFILES): The `mostlyclean` target was leaving a file,
- `groff.info-3`, behind in the build tree. At some point our
- Texinfo manual grew beyond earlier expectations. Use a glob
- `[0-9]` instead (giving a hostage to fortune that `makeinfo`
- will never split our manual into more than nine chunks).

- [nroff]: Support groff's -R flag to run refer(1).
-
- There's no reason not to support calling `refer` with nroff-mode
- documents; typographically, it's less demanding than tbl(1).
- GNU troff(1) supports an incompatible `-R` flag to suppress the
- reading of troffrc{,-end} files, but this is likely not the `-R`
- that users will want--it is most useful for troubleshooting
- troff, and nroff already unconditionally loads a macro file
- {tty-char.tmac}.

-2021-10-11 Paul Eggert <eggert@cs.ucla.edu>
-
- Include <config.h> before any standard headers.
-
- Gnulib requires that files that might use Gnulib features (which
- pretty much means every C or C++ source file) must include
- <config.h> first. Arrange for that. This will be needed once
- Groff updates to the latest Gnulib; see Bjarni Ingi Gislason's
- problem report in:
- <https://lists.gnu.org/r/bug-gnulib/2021-10/msg00008.html>
-
- The only exception I can see is src/utils/addftinfo/guess.cpp,
- which does not include any standard include file either directly
- or indirectly, and so need not include <config.h>.

- to be oblique.
- (MR): Add macro to format the text of a man page cross

- Define `an-lic` and `an-ic` strings as either empty or as

- [andoc,man,mdoc]: Fix Savannah #61266. Resolve problems in
- batch rendering of man pages to PDF arising from entanglement
- of end-of-input traps, page location traps, continuous rendering
- mode, and andoc's reloading of the (m)an and (m)doc packages.
-
- * tmac/andoc.tmac (reload-doc, reload-man): Remove end-of-input
- traps alongside others.
-
- * tmac/an.tmac (an-end): Only perform flush and "manual" page
- footer placement if in continuous rendering mode, since this
- macro is not only called by a trap placed only in continuous
- rendering mode, but also by andoc when changing macro packages.
- Unconditionally remove the `an-header` trap since the next
- document might be using a different macro package.
-
- * tmac/mdoc/doc-common: In initialization, set flag indicating
- that manual header placement will be required.
- (Dt): Call `doc-setup-header` (which sets up several types of
- trap) unconditionally, and break the page if the vertical
- drawing position is anywhere but at the top.
- (Os): If the package has just been initialized, call
- `doc-header` to force the page header to be written.
- (doc-end-macro): Remove `doc-header` trap since the next
- document might be using a different macro package. Break the
- page. Set flag indicating that manual header placement will be
- required for the next document.
-
- * tmac/mdoc/doc-ditroff (doc-setup-header): Only set page
- location traps for the header and footer if not continuously
- rendering.
- * tmac/mdoc/doc-nroff (doc-setup-header): Stop calling
- `doc-header` here if continuously rendering. Emit an
- unconditional break. Except for the location of the footer
- trap, the `doc-setup-header` implementations are now identical.
-
- Refactoring is needed: some macros and registers have misleading
- names, there is some code duplication in mdoc, and some of the
- trap management problems are solved in slightly different ways
- in man(7) and mdoc(7), perhaps unnecessarily. We also need some
- test scripts to protect us from regressions. But this fixes the

- [man]: Fix `U` enablement override so it actually works the way
- I had in mind.
- - The package proper enables it by default, but
- - the sample site configuration file switches it off, on the
- assumption that distributors and users will know better than
- we do when they get a capable pager in place, and
- - a register setting at the command line (or otherwise prior to
- the loading of the macro package) is dispositive.
-
- * tmac/an-ext.tmac: Rename URI output device capability register
- from `U` to `mU`.
- (UR, UE, MT, ME): Test both `U` and `mU` before handling
- hyperlinks specially.
- * tmac/an.tmac: If `man.local` did not initialize `U`, switch it

- arguments of varying types is a code smell--phew!)
- (tty_printer::special): Call `special_link()` member function if

- [ms]: Support user-defined TOC leader style.
-
- * tmac/s.tmac (toc*leader-char): Rename it as...
- (TC-LEADER): ...this; within PX, leave it unchanged, if
- predefined.
- (TC-MARGIN): New numeric register; if predefined, leave it
- unchanged, otherwise define as \w'000'; use it instead of
- hard-wired definition, within PX; see
- <https://savannah.gnu.org/bugs/?61157>.
-
- * tmac/groff_ms.7.man (TC-LEADER, TC-MARGIN): Document them.

-
- [pic]: Update input file name correctly.
-
- * src/preproc/pic/troff.cpp (troff_output::set_location): Copy
- the inbound file name argument with `strdup()` and store pointer
- to this copy in `last_filename` instead of aliasing argument.
- (troff_output::~troff_output): `free()` the memory allocated by
- `strdup()` in destructor.
-
- Fixes <https://savannah.gnu.org/bugs/?61206>. Pointer
- assignment instead of a string copy was being performed, which
- means that after its initial assignment, `last_filename` always
- shared its value ultimately with the `current_filename` pointer
- {a libgroff symbol}, so `strcmp()` was always being performed on
- identical pointers. Problem appears to date back 30+ years, to
- the dawn of our repo history.

- * font/devlj4/S: Make font name consistent with file name.
-
-2021-09-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libgroff/font.cpp (font::load): Throw error if a font
- description file is missing a `spacewidth` directive, since it
- is now re-documented as mandatory. Atypically, we don't return
- false in this scenario; instead we proceed with the existing
- logic to compute a space width for the font based on typical
- practices for Western alphabetic fonts (see, e.g.,
- <https://type.today/en/journal/spaces>.
-
- * font/devdvi/EX:
- * font/devdvi/MI:
- * font/devdvi/S:
- * font/devdvi/SA:
- * font/devps/EURO: Add `spacewidth` directive to font
- description files we ship that were missing it. We use the same
- values that libgroff would have computed, so there should be no
- visible difference.
-
-2021-09-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am: Mark `$(TEST_SUITE_LOG)` as `.PRECIOUS`. This
- prevents the test suite log from being deleted if there are any
- failures.

- for `TH` to a more appropriate location.
-
-2021-09-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grog]: Refactor to make it easier to generalize a per-package
- scoring mechanism.
-
- * src/utils/grog/grog.pl: Convert `inferred_main_package` from
- scalar to list. Add scalar `selected_main_package` to store a
- "winner" from the list of main packages inferred.
- (push_main_package): Add subroutine to populate
- `inferred_main_package`.
- (do_line, infer_man_or_ms_package): Update to use
- `push_main_package`.
- (construct_command): Rewrite to select a main package from the
- list `inferred_main_package`, taking user-supplied arguments
- into account as an overriding factor. Drop now-unused `msupp`
- list.
-
-2021-09-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp (main): If the `-I` option is given,
- run the grn preprocessor and pass it an `-M` option with `-I`'s
- argument.
-
- * NEWS:
- * src/roff/groff/groff.1.man (Options): Document it. Also
- document that `-I` options are passed to the output driver.
-
-2021-09-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/grog.pl (do_line): Don't strip groff-style
- comments \# if AT&T compatibility mode is enabled.
-
-2021-09-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Perform more font description file validation. Our
- documentation said that the `name` directive was mandatory but
- we didn't actually enforce this. Also be more specific in our
- complaints of ill-formedness.
-
- * src/libs/libgroff/font.cpp (font::load): Add local Boolean
- variable `saw_name_directive`. Rename `had_charset` to
- `saw_charset_directive` for symmetry. Emit distinct diagnostics
- for `spacewidth` and `slant` directives having a missing,
- non-numeric, or out-of-range argument. Emit diagnostic if the
- file lacks a `name` directive.
-
-2021-09-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Slightly refactor.
-
- * src/libs/libgroff/font.cpp (struct text_file): Rename member
- variable `size` to `linebufsize` for clarity (it's certainly not
- the size of the text file).
- (text_file::text_file): Initialize `linebufsize` in constructor.
- (text_file::next_line): Allocate new `buf` using `linebufsize`
- instead of magic number (which was also stored to `size`, making
- it only semi-magic, I guess). Rename local variable `i` to
- `length` since it is in fact the length (in `char`s) of the
- string stored in `buf`.
-
-2021-09-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Revisit fix for Savannah #61173.
-
- * src/libs/libgroff/font.cpp (text_file::text_file): Restore
- setting of `lineno` member variable to `0` in constructor
- initializer list, but...
- (text_file::next_line): ...unconditionally increment it every
- time through this member function's outer loop.
-
-2021-09-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Align diagnostic message format with libgroff.
-
- * src/roff/troff/input.cpp (fatal_with_file_and_line): Report
- the program name if one is defined.
- (fatal_with_file_and_line, error_with_file_and_line,
- debug_with_file_and_line): Report the line number of the input
- file only if it is positive, so that other values can be used
- for "whole file" complaints. See commit cd0457b6, 17 September.
-
-2021-09-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Drop redundant diagnostic.
-
- * src/libs/libgroff/font.cpp (font::load): Drop redundant
- diagnostic; a missing `charset` directive is already checked for
- later, circa line 998.
-
-2021-09-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Fix code style nits.
-
- * src/libs/libgroff/font.cpp (font::font): Use initializer list
- as much as possible in constructor.
- (font::unit_scale, font::get_width, font::get_height,
- font::get_depth, font::get_italic_correction,
- font::get_left_italic_correction,
- font::get_subscript_correction, font::get_character_type,
- font::get_code, font::get_special_device_encoding): These member
- functions rely on the font being either indexed or associated
- with an output device that uses the `unicode` directive in its
- `DESC` file. The compiler doesn't know this, so annotate the
- `abort()` calls that conclude them. Add an `assert()` before
- each one to more usefully describe the violated invariant in the
- event this unreachable code is somehow reached.
- (font::get_width): Annotate special meaning of zero zoom factor.
-
-2021-09-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/include/font.h (UNDEFINED_GLYPH): Use idiomatic C++98 null
- pointer constant.
-
-2021-09-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grohtml]: Fix compiler warning and dead store.
-
- * src/devices/grohtml/post-html.cpp (html_printer::special):
- Update call of `font::load_font()` to stop passing obsolete
- parameter (deleted by me in 2dff87d3, 17 September). The value
- stored to the parameter by that function was never read anyway,
- so also get rid of the variable that contained it.
-
- Fixes <https://savannah.gnu.org/bugs/?61187>. Thanks to Bjarni
- Ingi Gislason for the report.
-
-2021-09-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Slightly refactor.
-
- * src/include/font.h (font::scan_papersize): Demote return type
- from `int` to `bool`.
- * src/libs/libgroff/font.cpp (font::scan_papersize): As above.
- Use Boolean instead of integer literals. Also rename `FILE`
- stream pointer from `f` to `fp` and perform an explicit
- comparison against the idiomatic C++98 null pointer constant.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff, troff]: Slightly refactor device and font description
- file loading. Remove dead code.
-
- * src/include/font.h (font::load_font): Drop second parameter.
- It was never used for its intended purpose.
- (load): Drop first parameter; likewise.
- * src/libs/libgroff/font.cpp (font::load, load): As above.
-
- * src/libs/libgroff/font.cpp (struct text_file): Rename
- `skip_comments` to `recognize_comments`. Demote that and
- `silent` from `int` to `bool`.
- (text_file::text_file): Use Boolean rather than integer literals
- in constructor.
- (text_file::next_line, font::load): Apply above renaming.
-
- * src/libs/libgroff/font.cpp (font::load): Rename parameter from
- `head_only` to `load_header_only` to be more communicative.
- Drop test of font description file name being `DESC`; this code
- was not being reached. Stop throwing errors from this function
- on failure to open the file; the caller will handle this when it
- sees our false return value. Rename local variable `command` to
- `directive` for alignment with our documentation. Replace "I
- dont think this should happen" test and comment with `assert()`.
- (struct table): Rename member from `command` to
- `numeric_directive` to indicate its specificity, tracking only a
- subset of valid `DESC` file directives.
-
- * src/libs/libgroff/font.cpp (font::load, font::load_desc):
- Remove redundant assignments to the member variable formerly
- known as `skip_comments`.
-
- * src/libs/libgroff/font.cpp (font::load_desc): Rename local
- variable `directive_found` to `numeric_directive_found` to
- clarify logic.
-
- * src/roff/troff/node.cpp (mount_font_no_translate): Simplify
- call of `font::load_font`. The `not_found` in-out parameter
- which was so agonizingly passed up through layers of library
- calls was never actually read. Drop code that has been `#if
- 0`-ed out since 1993.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libgroff/font.cpp (font::load_desc): Clear line
- number before emitting whole-file validity diagnostics.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libgroff/font.cpp (font::load_desc): Emit correct
- line numbers when complaining of invalid `sizescale`, `hor`, or
- `vert` values in device description files.
-
- Fixes <https://savannah.gnu.org/bugs/?61174>.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Increase validation of device and font description
- files.
-
- * src/libs/libgroff/font.cpp (font::load): Validate the syntax
- and value of the `name` directive.
- (font::load_desc): Issue distinct diagnostics for a `fonts`
- directive that is missing arguments and for a first argument
- that can't be interpreted as a valid number.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Make error reporting more flexible.
-
- * src/libs/libgroff/error.cpp (do_error_with_file_and_line):
- Interpret a nonpositive line number specially: treat the
- diagnostic as applying to the entire file, and omit the line
- number.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Add information to diagnostics.
-
- * src/libs/libgroff/font.cpp (font::load): Drop unused argument
- from `error()` call.
- (font::load_desc): In another, add name of numeric directive
- that is given an unparsable number.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Tweak code style.
-
- * src/libs/libgroff/font.cpp (trim_args, font::load)
- (font::load_desc): Compare pointer explicitly to null pointer
- literal `0` instead of using logical complementation.
- (font::load, font::load_desc): Swap order of null pointer
- equality comparisons when a typo or thinko could lead to lvalue
- assignment.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Use idiomatic C++98 null pointer constant.
-
- * src/libs/libgroff/font.cpp (text_file::error)

- (font::load):

- * src/libs/libgroff/tmpfile.cpp (temp_init::temp_init):
- * src/libs/libgroff/tmpname.cpp (gen_tempname): Use `0` literal
- instead of `NULL` to represent a null pointer; this was
- idiomatic in C++98 and is mostly the practice elsewhere in
- groff. Also swap order of null pointer equality comparisons
- when a typo or thinko could lead to lvalue assignment.
-
- * src/roff/troff/input.cpp (input_stack::diversion_state)
- (input_stack::get_diversion_state, charinfo::contains)

- [libgroff]: Slightly refactor.
-
- * src/libs/libgroff/font.cpp (font::load): Use same loop style
- as `font::load_desc()`.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Fix off-by-one error in font and device description
- file reader diagnostics.

-
- Fixes <https://savannah.gnu.org/bugs/?61173>.
-
-2021-09-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Boolify more interfaces.
-
- * src/include/font.h (font::unit_scale):
- * src/libs/libgroff/font.cpp (font::unit_scale): Demote return
- type from `int` to `bool`. Use Boolean literals instead of
- integers.
-
- * src/libs/libgroff/font.cpp (struct text_file): Rename `next`
- member function to `next_line`. Demote its return type from
- `int` to `bool`. Use Boolean literals instead of integers.
-
-2021-09-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Boolify local variables.
-
- * src/libs/libgroff/font.cpp (font::load, font::load_desc):
- Demote local variables used as Booleans from `int` to `bool` and
- update literals used with them from integer to Boolean.
-
-2021-09-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grn, groff, troff]: Communicate better when device DESC file
- can't be loaded.
-
- * src/libs/libgroff/font.cpp (font::load_desc): Stop writing
- diagnostic to standard error.
- * src/preproc/grn/main.cpp (getres):
- * src/roff/troff/troff.cpp (main): Replace "sorry, I can't
- continue" fatal diagnostic with a more informative message.
- Instead say which device's DESC file the program was trying to
- open, which might reveal a user's logic error or typo.
- * src/roff/groff/groff.cpp (main): Replace "invalid device" text
- of fatal diagnostic similarly. I think it is more helpful to
- indicate the operation that failed rather than saying the device
- was invalid, particularly since there are other ways for a
- device description to be invalid even if a DESC file is found
- and loaded.
-
-2021-09-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Throw warning diagnostic if device DESC file attempts
- to load unavailable fonts.
-
- * src/roff/troff/input.cpp (main): Take advantage of new Boolean
- return values of `mount_style()` and `mount_font()` to produce
- warning diagnostics if mounting a style or font as directed by
- the DESC file fails. Explain in a comment why, at present, this
- style mount warning will never actually trip.
-
-2021-09-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Lift font mounting diagnostic messages to be closer to
- their user-controlled contexts to provide more information. In
- many cases no diagnostic was being thrown at all when an
- unavailable font was requested by name, which is the method most
- users prefer, and which meant that failures resulting from typos
- in font names for many requests (`uf`, `fschar`, `rfschar`,
- `special`, `fspecial`, `fzoom`, `bd`, `tkf`, `cs`) were going
- unreported. Further, promote these font warnings to errors
- because the request will utterly fail to do what was requested
- with no reasonable fallback. Possibly, they were formerly
- warnings because at the low level they were being emitted, they
- could also have originated from unavailable fonts encountered in
- device description files, and while that's bad news, it results
- in no formatting problems if it doesn't affect fonts that an
- input document actually uses.
-
- * src/roff/troff/node.cpp (struct font_lookup_info): New struct
- keeps the font name or position requested, and the position of
- successful font lookup.
- (font_lookup_info::font_lookup_info): Add constructor.
- (font_lookup_error): New function builds error message using a
- `font_lookup_info` struct and a message argument.
- (get_fontno): Rename to...
- (has_font): ...this. Add argument to take a pointer to a
- `font_lookup_info` struct. Return a `bool` indicating whether
- the lookup succeeded. Place former `int` return value into the
- struct instead. Populate the other struct members with the
- requested font name or position, as appropriate.
- (mount_font_no_translate): Stop throwing warning diagnostic here
- if a font cannot be loaded. Instead, throw them...
- (font_position): ...here, and...
- (underline_font, define_font_special_character,
- remove_font_special_character, read_special_fonts,
- font_special_request, font_zoom_request, bold_font, track_kern,
- constant_space): ...here, using `font_lookup_info` structs and
- `has_font()`.
- (remove_font_special_character): Stop returning early if font
- lookup fails; it's gratuitously inconsistent with other similar
- functions (save one, which has a reason to be different).
- (define_font_special_character): Return early if font lookup
- fails and say why in a comment (we can't `skip_line()`).
-
- Fixes <https://savannah.gnu.org/bugs/?59522>.

-2021-09-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * [libgroff, troff]: Further boolify.
-
- * src/include/font.h (load_font, font): Demote parameters from
- {pointer to} `int` to `bool` and update default literal from
- integer to Boolean (except for the pointer). Update comment.
- * src/libs/libgroff/font.cpp (load_font, load): Similarly.
-
- * src/roff/troff/node.h (mount_font):
- * src/roff/troff/node.cpp (mount_font): Demote return type from
- `int` to `bool`.
-
- * src/roff/troff/node.h (mount_style):
- * src/roff/troff/node.cpp (mount_style): Promote return type
- from `void` to `bool`.
-
- * src/roff/troff/node.cpp (mount_font_no_translate): Demote
- return type and `check_only` parameter from `int` to `bool` and
- use Boolean rather than integer literals with them.
- (check_font): Update call site of `mount_font_no_translate` to
- use Boolean literal.
- (font_position): Indicate that "error" is ignored by casting
- return value of `mount_font` to void instead of using a comment.
- (style): Cast return value of `mount_style` to `void`.
-
-2021-09-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am: Add `.DELETE_ON_ERROR` special target; both GNU
- and FreeBSD make(1)s support it so maybe it will be portable
- enough. This avoids, among other problems, a target appearing
- falsely up-to-date (often as an empty file) when the troff
- process generating it experiences an assertion failure.

-
- Since June 1991 if not earlier, groff (technically, the refer,
- lookbib, and lkbib programs) has trusted the header contents of
- binary bibliographic index files (canonically generated with
- indxbib(1)) regarding the sizes of the data structures that
- follow in the file, a notorious class of security problem. In
- July 2013, the Mayhem Team at Carnegie Mellon University
- reported to the Debian Bug Tracking System a problem with
- groff's refer(1) implementation dumping core when reading an
- index file prepared by a fuzzer.
-
- * src/libs/libbib/index.cpp (index_search_item::check_header):
- Add new member function to validate the header of an indexed
- bibliography file, returning a string describing in detail the
- first validity problem encountered.
- (index_search_item::load): Perform the foregoing check before
- using any of the size values taken from the header; they are
- relied upon for pointer arithmetic. If in verification mode
- {using the undocumented `-V` flag to refer(1), lkbib(1), or
- lookbib(1)}, report the details of the problem encountered.
- Regardless of that mode, if there is a validity problem, report
- corruption of the index file and abandon it, forcing fallback to
- the text version of the corresponding bibliography file.

- Fixes <https://bugs.debian.org/716109>.

-2021-09-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libbib/index.cpp
- (index_search_item::get_invalidity_reason): Don't complain about
- a last list element being nonnegative if the list size was zero
- in the first place, as can happen with an empty index. More
- seriously from a language standpoint, avoid reading through a
- negative array index (this can escape a compiler's attention
- because we're reading from the midst of a heap-allocated or
- `mmap()`ed region, but it's still a code smell).

- Fixes <https://savannah.gnu.org/bugs/?61144>.

-
- * src/libs/libbib/index.cpp (index_search_item::load)
- (index_search_item::get_invalidity_reason)
- (index_search_item::add_out_of_date_file): Clarify diagnostic
- messages. Make it more obvious when we're complaining of a
- problem in an indexed bibliographic database file (rather than a
- plain text one). Dial down the amount of Unix jargon a little.
-
-2021-09-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libbib]: Partially boolify.
-
- * src/include/search.h:
- * src/libs/libbib/index.cpp:
- * src/preproc/refer/refer.cpp:
- * src/utils/lkbib/lkbib.cpp:
- * src/utils/lookbib/lookbib.cpp: Demote `verify_flag` from an
- `int` to a `bool`, rename it to `do_verify`, use Boolean
- instead of integer literals with it, and update call sites.
-
- * src/libs/libbib/index.cpp: Rename `do_verify()` member
- function to `get_invalidity_reason()` (it returns a string).
- Demote `load()` from `int` to `bool`; do the same for `verify()`
- and rename it to `is_valid()` as well. Use Boolean instead of
- integer literals with them.
- (index_search_item::is_valid, make_index_search_item): Update
- call sites of renamed member functions.
-
-2021-09-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/libs/libbib/map.c (mapread): Compare return value of
- `mmap()` to `MAP_FAILED` instead of `(char *)-1`. `MAP_FAILED`
- is documented in POSIX Issue 5 a.k.a. SUSv2
- <https://pubs.opengroup.org/onlinepubs/007908799/xsh/mmap.html>
- {1997} and should be portable enough by now.

-2021-09-11 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Clamp negative tab stop positions to zero instead of
- throwing an assertion failure.
-
- * src/roff/troff/env.cpp (tab_stops::distance_to_next_tab):
- Replace `assert` with clamping logic, ensuring that `lastpos`
- can never be negative. While negative tab stop positions don't
- make much sense (they result in zero horizontal motion), user
- input like `.ta T -5` should never provoke an assertion failure.
-
- (set_tabs): Throw range warning in additional scenario, viz., if
- a repeating tab offset is negative.

-
- [troff]: Boolify `set_tabs` function.
-
- * src/roff/troff/env.cpp (set_tabs): Demote local variables from
- `int` to `bool` and give them predicate-like names.
- - `first` -> `is_first_stop`
- - `repeated` -> `is_repeating_stop`
- Use Boolean instead of integer literals in assignments to them.

-
- [troff]: Make `ab` request quiet if given no arguments. The
- `tm`, `tm1`, and `tmc` requests provide ample flexibility for
- constructing diagnostic messages prior to an error exit, and
- it's convenient to make `ab` itself quiet instead of saying
- "User Abort." as Unix Version 7 troff did. Further, there is no
- standardization across troffs regarding what `ab` should emit if
- arguments are absent.
-
- * src/roff/troff/input.cpp (abort_request): Do it.
-
- * src/roff/groff/tests/ab_works.sh:
- * src/roff/groff/groff.am (groff_TESTS): Test it.

-
- [troff]: Drop unused member function.
-
- * src/roff/troff/token.h (class token): Drop unused `title`
- member function. Its implementation was apparently removed in
- the prehistory of our Git repository: see James Clark's
- ChangeLog entry of 1990-09-06.
-
-2021-09-06 G. Branden Robinson <g.branden.robinson@gmail.com>

-2021-09-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/env.cpp (do_underline_special): Refactor
- slightly.
- - Rename `underline_spaces` -> `do_underline_spaces`.
- - Demote it from an `int` to a `bool`.
- - Use ternary operator and explicit character literals when
- writing device control command instead of doing arithmetic
- on a character literal.
- - Update call sites to use Boolean literals.
- - Relocate function to avoid forward reference.

-
-2021-09-04 Keith Marshall <keith.d.marshall@ntlworld.com>

-
-2021-09-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/env.cpp (distribute_space): Refactor slightly.
- - Rename `force_reverse` to `force_reverse_node_list`.
- - Rename `reverse` to `do_reverse`.
- - Demote both of the above from `int` to `bool`.
- - Use Boolean literals with them.
- - Add assertions to enforce positive values of `nspaces` and
- `desired_space`.
- - Remove now-redundant test for `nspaces` being positive.
- - Add explanatory comments.
- (environment::wrap_up_field): Update call sites of
- `distribute_space` when non-default value of
- `force_reverse_node_list` is supplied.
-
-2021-09-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Don't adjust nonadjustable lines. This means that the
- direction from which an output line in adjustment mode "b" (or
- its "n" synonym) is filled with supplemental space is not
- changed if that output line does not require adjustment. This
- will result in whitespace changes to documents using that
- adjustment mode, and these changes will be plainly visible on
- low-resolution output devices like terminals.
-
- To illustrate, in the following "A" means an output line
- requiring adjustment; "F" a line that is "full" and does not;
- and "L" and "R" indicate distribution of adjustment spaces from
- the left and right, respectively.

-
- * src/roff/troff/env.cpp (distribute_space): Return early if
- either the amount of desired space to be distributed or the
- count of space nodes in the output line to distribute it among
- is zero.
-
- * tmac/tests/an_TH-repairs-ad-damage.sh: Update test to expect
- space to be distributed differently.

- it.
-
-2021-08-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * m4/groff.m4 (TRADITIONAL_CPP): Update `AC_MSG_CHECKING`
- argument to refer to "pre-ISO C90 syntax" instead of a
- "traditional" preprocessor. Call `AC_MSG_ERROR` (aborting
- configuration) if the check (for pre-C90 transformation)
- succeeds. We thus withdraw support for such superannuated
- {"Reiser"} C preprocessors.

-
-2021-08-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Drop support for `TRADITIONAL_CPP`. This means a C

-
-2021-08-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Drop support for `ARRAY_DELETE_NEEDS_SIZE`.
-
- * src/include/lib.h [ARRAY_DELETE_NEEDS_SIZE]: Drop preprocessor
- conditional branch. This abandons support for certain pre-ISO
- C++98 compilers. (According to a now-removed comment, unsized
- array deletion was documented in "ARM", meaning _The C++
- Annotated Reference Manual_, published in 1989.)
-
- * Makefile.am: Undocument preprocessor symbol.
-
-2021-08-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Drop redefinition of `INT_MIN`.
-
- * src/include/lib.h: Drop redefinition of `INT_MIN`. It was
- motivated by a bug in the AT&T C++ compiler (cfront), version
- 2.0, released in June 1989. Implementations have had 30 years
- to get this right; assume that they have.
-
- * PROBLEMS: Drop corresponding item.
-
-2021-08-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Drop long-dead `COOKIE_BUG` logic.
-
- * src/libs/libgroff/new.cpp (operator new, operator delete):
- Drop preprocessor conditional branches on the `COOKIE_BUG`
- symbol. This was de-documented, and an autoconf check for its
- necessity removed, way back in groff 1.10 (November 1995). It
- was relevant only to GCC from versions 2.0 to 2.2.2 (all 1992).
-
-2021-08-24 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Refactor `font::scan_papersize()`.
-
- * src/libs/libgroff/font.cpp (font::scan_papersize): Ensure
- successful return value of `fgets()` before attempting to parse
- string for paper format. Convert `test_file` to Boolean and
- rename to `attempt_file_open`. Quiets GCC `-Wunused-result`
- warning.
-
-2021-08-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [tests]: Apply naming convention.

- language programmers are comfortable with the interchangeability
- of subtraction and comparison, but not everyone is).
-

- Document `\O2`, `\O3`, `\O4`, and `\O5` escape sequences.
-
-2021-08-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- groff(7): Fix bug in `\?` escape rendering.
-
- * man/groff.7.man (ESC?): Fix bug in page-private macro: the
- question mark that ends this uniquely-syntaxed escape sequence
- was not shown with the mandatory escape character before it.
- Problem dates back at least to commit 41b0e794, 19 February
- 2007, but possiby to f790bc7a9, 6 January 2002.

-2021-08-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Treat an empty $GROFF_TYPESETTER as unset.
-
- * src/libs/libgroff/device.cpp (device_init::device_init): Test
- both returned pointer from `getenv()` and, if that's not null,
- the first character of the string for nullity before assigning
- it to `device`.
-
- Fixes <https://savannah.gnu.org/bugs/?61068>.

-2021-08-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [libgroff]: Rename font class member variable.
-
- * src/include/font.h (font class): Rename `unscaled_charwidths`
- member variable to `use_unscaled_charwidths`: since it is a
- Boolean, make it read more like a logical predicate.
-
- * src/libs/libgroff/font.cpp (font::get_width, font::load_desc):
- * src/libs/libgroff/fontfile.cpp (font class): Update
- initialization and assignments.
-
-2021-08-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (get_copy): Demote integer arguments
- to Booleans and use Boolean literals for default values. Rename
- `defining` to `is_defining`.
- (get_char_for_escape_name, do_define_macro): Update call sites
- that use non-default arguments to use Boolean literals and
- comments to document what's being requested.
-
-2021-08-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am (DOC_GROFF_ONLY): Stop running groff in unsafe
- mode; no documents (in _this_ directory) appear to require it.

-
- [grn]: Fix code style issues.
-
- * src/preproc/grn/hgraph.cpp:
- * src/preproc/grn/hpoint.cpp:
- * src/preproc/grn/main.cpp:
- * src/preproc/grn/hdb.cpp: Drop use of `register` storage class.
-
- Fixes <https://savannah.gnu.org/bugs/?57733>. Thanks to Bjarni
- Ingi Gislason for the report and a suggested patch.
-
- * src/preproc/grn/hgraph.cpp (len, HGPrintElt, picurve):
- * src/preproc/grn/hdb.cpp (DBRead): Wrap long lines.
-
- * src/preproc/grn/hgraph.cpp: Rename function from
- `Paramaterize` to `Parameterize`.
- (HGCurve): Update call site.
-
- * src/preproc/grn/main.cpp (add_file): Drop redundant cast in
- `realloc()` call.
- (conv, interpret): Use standard English in diagnostic messages.
-
-2021-08-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/grn/hdb.cpp: Perform more input validation.
- Improve diagnostics by taking advantage of libgroff
- infrastructure and tracking the line number of the input file.
- Add global `lineno`.
- (DBRead): Increment `lineno` after reading newlines from input.
- Call `error_with_file_and_line()` instead of `error()`. If
- input reports a negative length for the text (string) to follow
- in the file, exit with a fatal diagnostic. Check for EOF while
- reading text string.
- (DBGetType): Convert `fprintf()` call for warning diagnostic to
- `warning_with_file_and_line()`.
- (DBRead, DBGetType): Add contextual information to diagnostic
- messages.
-
- Fixes <https://savannah.gnu.org/bugs/?61043>. Thanks to

- * src/preproc/grn/main.cpp (usage): Update usage message.
-
-2021-08-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grn]: Add and use `malloc()` wrapper.
-
- * /src/preproc/grn/main.cpp (grnmalloc): New function takes
- argument of `size_t` type and constant string argument to
- describe what is being allocated. Return non-null pointer from
- `malloc()`, otherwise call `fatal()`, describing what was being
- allocated and the problem reported by the system.
-
- * src/preproc/grn/hdb.cpp (DBCreateElt):
- * src/preproc/grn/hpoint.cpp (PTMakePoint):
- * /src/preproc/grn/main.cpp (main, interpret): Migrate
- `malloc()` callers to `grnmalloc()`.
-
-2021-08-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/grn/hdb.cpp (DBRead): Check return value of
- `sscanf()` and call `fatal()` if no conversions succeeded. The
- blithe discard of a useful return value is bad enough, but this
- one took place inside a do-while such that it could loop
- forever trying fruitlessly to parse two doubles out of strings
- that didn't contain them (the loop never checked the EOF status
- of the file stream from which it was reading, and relied on
- `fgets()` to keep advancing the stream pointer). Discovered
- while root-causing Savannah #61043.
-
-2021-08-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Resolve compiler warnings relating to format string security and
- ISO C++98 conformance.
-
- * src/preproc/eqn/delim.cpp (define_extensible_string):
- * src/preproc/pic/pic.ypp (do_sprintf): Use #pragma to silence
- GCC "format-nonliteral" warning and explain why our usage is
- safe in a comment.
-
- * src/preproc/preconv/preconv.cpp (detect_file_encoding): Use
- `l` modifier to `%u` `fprintf()` conversion instead of `z`, and
- cast return values of `size_t` to unsigned long; "ISO C++98
- does not support the ‘z’ gnu_printf length modifier" (it doesn't
- support `ll` either). N.B. this is debugging output only.
-
- * src/roff/groff/groff.cpp (synopsis):
- * src/roff/troff/input.cpp (usage): Repeat variadic argument for
- `%s` conversion in `fprintf()` call because "ISO C++98 does not
- support %n$ operand number formats".
-
- * src/roff/troff/env.cpp: Initialize adjustment and hyphenation
- mode enums without commas at the end of the enumeration lists.
-
-2021-08-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [man]: Clean up the interface between `an-footer` and `BT`, and
- HTML header and footer suppression generally. Move
- responsibility for checking the `ps4html` register from the
- latter to the former. This is not something a `BT` redefiner
- {see groff_man(7)} should have to worry about.
-
- * tmac/an.tmac (BT): Drop test of `ps4html` register and early
- return.
- (an-header, an-footer): Return immediately if
- `an-suppress-header-and-footer` is true. Remove conditional on
- `an-is-output-html`.
- (initialization): Define `an-suppress-header-and-footer`
- register; true if `an-is-output-html` is true, or if `ps4html`
- is defined.
-
-2021-08-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/html/pre-html.cpp (get_resolution): Unbrace a
- single-statement `while` loop per prevailing coding style. Add
- comments noting how we aren't parsing DESC files _precisely_ as
- our documentation specifies.
-
-2021-08-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Convert font class `int` members to `bool` where appropriate.
-
- * src/include/font.h (font class): Demote integers to Booleans
- and use Boolean literals where possible. Rename some member
- variables to look like logical predicates.
- - contains()
- - is_special()
- - has_ligature()
- - tcommand -> has_tcommand
- - unscaled_charwidths
- - pass_filenames
- - use_charnames_in_special
- - is_unicode

- * src/libs/libgroff/font.cpp (font::font): Construct object
- using Boolean literal.
- (font::contains):
- (font::is_special):
- (font::has_ligature): Convert return type to `bool`.
- (font::load):
- (font::load_desc): Assign to member variables using Boolean
- literals.
- * src/libs/libgroff/fontfile.cpp: Initialize appropriate globals
- using `bool` type and Boolean literals.
- * src/roff/troff/troff.h:
- * src/roff/troff/input.cpp (main):
- * src/roff/troff/node.cpp (troff_output_file::put_char_width):
- Rename `tcommand_flag` to `device_has_tcommand` to suggest a
- logical predicate, and to emphasize the formatter's concern with
- what the output device can accept in the intermediate output
- language.
- * src/roff/troff/input.cpp: Initialize `device_has_tcommand`
- global using `bool` type and Boolean literal.

-
- [me]: Clarify breadth of application of `ll` macro.
-
- * doc/meref.me: Document application of .ll macro only to the 3
- environments that me(7) uses, not any the user might create.

-
- Fixes <https://savannah.gnu.org/bugs/?55060>.

-
-2021-08-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/e.tmac (bc): Fix problem with multiple columns on long

- mode for the pattern files, plus 2 as is traditional in ms).
-
-2021-08-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/e.tmac (1c): Place comment escape sequence immediately
- after macro argument. (When redefining a request, one needs to
- remember that request arguments are not parsed exactly as macro
- arguments are.) Quiets "-w tab" warning.
-
-2021-08-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [me]: Fix misleading documentation claim; gremlin(1) pictures
- cannot be included directly; they must be preprocessed with

-
- [me]: Fix PS/n1 combination diagnostic spew and apparent logic
- error.
-
- * tmac/e.tmac (@h): Place comment escape sequence immediately
- after macro argument. (When redefining a request, one needs to
- remember that request arguments are not parsed exactly as macro
- arguments are.)
- (n2): Prefix with `do` requests using long register names.
- (n2): Add macro-local register `|l` to store length of first
- argument. Don't attempt to extract a substring beyond the
- bounds of its source, which produces a warning diagnostic.
- (&&): Define no-op macro for use as end macro in nested macro
- definition.
- (PS): Fix unbalanced-else diagnostic by changing `if` to `ie`.
- (PS): Initialize `PS_nm_cnt` register to 0 instead of relying on
- implicit definition.
- (PS): Prefix with `do` definition of long macro name.
- (PS): Indent call of end macro.
- (PS): Add comment after escaped space.
- (PS, PF): Prefix with `do` call of long macro name.

-
- GNU pic recognizes two possible endings of a pic block: .PE or
- .PF. This fact was documented in doc/pic.ms but not in the pic
- man page. The minimal pic implementation provided by pic.tmac
- also did not include a .PF definition.
-
- * src/preproc/pic/main.cpp (main): Add dummy definition of `PF`
- macro.
- * tmac/pic.tmac (PF): Add macro that performs indentation only.
- (PE): Call PF for indentation.
-
- * doc/pic.ms (Interface to [gt]roff/How Scaling is Handled):
- * src/preproc/pic/pic.1.man (Description, Options): Mention `PF`
- in addition to `PS` and `PE`.

-
- * tmac/refer-ms.tmac:
- * tmac/s.tmac (fn@init, @PP): Rename strings
- `fn@sup-{start,end}` to `fn@mark-{start,end}`. This makes it
- more clear that the strings are brackets for the footnote
- marker, and not so much to do with the note text. Further, in
- nroff mode, they aren't superscripts at all, but bracket glyphs.
-
-2021-08-02 G. Branden Robinson <g.branden.robinson@gmail.com>

- Addresses part of <https://savannah.gnu.org/bugs/?57667>.
-
-2021-08-02 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/refer-ms.tmac: Use `fn@sup-{start,end}` instead of
- `par@sup-{start,end}` when setting refer(1) citation labels.
- This improves the appearance of the default labels on nroff
- devices. Continues commit caeede07, 1 May.
-
-2021-08-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tman/an-ext.tmac (EX, EE): Stop manipulating hyphenation.
- It's redundant since disabling fill mode already prevents
- automatic breaking, and therefore automatic hyphenation.
- * tmac/groff_man.7.man.in (Description/Document structure
- macros) <EX, EE>: Update documentation.
-
-2021-08-01 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/grog.pl: Update authorship credits. I appear
- to have removed or refactored all of the "device" (recte: macro
- package) inference logic adapted from Ralph Corderoy's grog.sh;
- see commit 3617f42048f54cc3f0adc282ee3b9e481c75ebd5, 13 June
- 2014.
-
-2021-07-31 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/grog.pl: Refactor through relocation and
- renaming. Move several global objects into subroutines.
- - `@request` -> `&do_line`
- - `@macro_ms`, `@macro_man`, `@macro_man_or_ms` ->
- `&infer_man_or_ms_package`
- - `@main_package` -> `&construct_command`
- Rename some objects for clarity.
- - `%Groff` -> `%score`
- - `@filespec` -> `$input_file`
- Delete unused object.
- - `@standard_macro`
- Add comments.
-
-2021-07-31 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/grog.pl (do_line): When matching macro/request
- names, accept any non-whitespace character (Perl: \S) instead of
- just a word-constituent character (Perl: \w), since roff
- identifiers can contain unusual characters (refer(1) and
- groff_me(7) illustrate some real-world cases).
-
-2021-07-31 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/grog.pl: Refactor macro package inference.
- - Stop manually populating `Groff` hash. (It's itching for a
- rename.)
- - Stop calling now-dead subroutine `infer_macro_packages`.
- (do_line): Always store the names of all macros called to the
- `Groff` hash, incrementing it. Now it's a proper scoreboard.
- Populate `inferred_main_package` from here upon encountering
- characteristic (i.e., uniquely named) macros of each package.
- Bug fix: drop "SP" from list of characteristic mom(7) macros;
- it's shared with mm(7).
- (infer_man_or_ms_package): Update comment. Return 0 (false) if
- document appears to be "raw", using no full-service macro
- package.
- (infer_macro_packages): Delete; do_line() does this work.
-
-2021-07-31 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/grog.pl: Refactor preprocessor inference.
- - Add new list, `inferred_preprocessor`.
- - Drop preprocessor-related keys from `Groff` hash.
- - Drop scalar `inside_tbl_table`.
- (do_line): Set up hash `preprocessor_for_macro`. Detect
- preprocessor macros the way the preprocessors do, explained in a
- comment. Respect AT&T compatibility mode when doing so. Build
- list of inferred preprocessors. This replaces the extensive and
- gaseous series of `if` statements that manipulated the `Groff`
- hash.
- (infer_preprocessors): Completely replace. Set up a hash
- `option_for_preprocessor` mapping preprocessor names to groff
- options (where applicable). Append to `command` and
- `preprocessor` lists as appropriate. Sort the preprocessor
- options so they don't move around in the argument list depending
- on the order of their macros' appearance in the input.
-
- * src/utils/grog/tests/smoke-test.sh: Update test cases to
- expect preprocessor options to show up in sorted order.
-
-2021-07-31 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/grog/grog.pl: Drop dead code. Delete global

-
-2021-07-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grohtml]: Fix code nit.
-
- * src/preproc/html/pre-html.cpp (get_image_generator):
- Type-qualify `keyword_len` as `const` to encourage the compiler
- to compute this value (the length of a string literal) at build
- time.
-
-2021-07-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Slightly refactor.
-
- * src/roff/troff/node.cpp: Add static `image_filename_len` to
- store length of cached image file name, so we don't wastefully
- recompute its length every time one is re-used.
- (suppress_node::tprint): Compute image file name length only
- when saving a new image file name. Use saved length in later
- expressions.
- (min): Drop unused inline function.
-
-2021-07-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Fix regression (breaking important pdfmark/pdfroff
- features) caused by my commit
- e876d4bfd193abb9a7d1fb6e76519349bded482a, 27 July. An empty
- image file name is in fact semantically valid when writing a
- bounding box; pdfmark uses such boxes to frame hyperlinks.
- Avoid null pointer dereference by initializing `image_filename`
- to an empty string literal. Thanks to Tadziu Hoffman and Keith
- Marshall for their patient explanations.
-
-2021-07-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Refactor some internal functions.
-
- * src/roff/troff/node.cpp: Rename two functions that have only
- one caller.
- - get_reg_int -> get_register
- - get_reg_str -> get_string
- We now have:
- (get_register, get_string): Use `assert()` aggressively because
- these are deeply internal and validation is imperative. Get rid
- of diagnostic messages (one of which perpetuated the dubious
- "number register" nomenclature) accordingly.
- (fetch_register): Also rename `prev_value`, misleadingly
- specific and seemingly copy-and-pasted out of a context where an
- auto-increment or -decrement might have been applied. It's just
- the `value`.
- (suppress_node::tprint): Update call site.
-
-2021-07-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Refactor `get_value` member functions. Given their
- names and popular "getter/setter" paradigms from many OO
- languages, the return type is misleading. Change it from `int`
- to `bool` since it returns only a success/failure status and
- modifies an argument (passed by reference) to deliver the
- requested data.
-
- * src/roff/troff/reg.h (reg, variable_reg):
- * src/roff/troff/div.cpp (page_offset_reg, page_length_reg)

- (distance_to_next_trap_reg, page_number_reg, no_space_mode_reg):
- * src/roff/troff/env.cpp (int_env_reg, vunits_env_reg)
- (hunits_env_reg, horizontal_place_reg):
- * src/roff/troff/input.cpp (writable_lineno_reg):
- * src/roff/troff/reg.cpp (reg, number_reg, variable_reg): Update
- class and member function definitions to reflect the new type.
- Update member function definitions to return appropriate Boolean
- literals instead of 0 and 1.

-
- [grohtml]: Fix Savannah #60981. Refactor device description
- file handling and make it more robust. Make pre-grohtml's
- -F option work as documented and honor device description file
- semantics documented in groff_font(5).
-
- * src/preproc/html/pre-html.cpp: Store partial filespecs of HTML
- and PostScript device files in constant strings.
- (get_resolution): Initialize `res` to zero. Only `free()` the
- pointer `pathp` if `open_file()` succeeded (populating it).
- Stop checking for valid `sscanf()` conversions of an integer to
- store in `res`, and don't return early. Instead process the
- whole DESC file; per our Texinfo manual and groff_font(5),
- "Later entries in the file ... override previous values."
- (get_image_generator): Add new function, paralleling
- `get_resolution()`, replacing open-coded logic in `main()`.
- Only the body of the `while` loop significantly differs.
- Instead of using `sscanf`, process the input character by
- character matching the keyword and {1,} spaces or tabs
- after it. Whatever follows in `linebuf` must be the program
- name.
- (imageList::createPage): Add `assert()` to cause failure if an
- empty image generator program gets this far, because it creates
- repeated messes if it does. (Something isn't checking exit
- statuses.)
- (main): Condense `image_gen` collection to a function call, a
- null pointer check, and a fatal diagnostic. Add a sanity check
- and a fatal diagnostic if the PostScript resolution is garbage.
- {It's initialized to -1 and `get_resolution()` will return 0 if
- it doesn't find one.}

- Fixes <https://savannah.gnu.org/bugs/?60981>.

- [grohtml]: Delete or rename `debug` symbols to avoid clash with

-
- * src/preproc/html/pre-html.cpp: Update a comment to refer to

- `debugging`.
- (html_system, imageList::createPage, imageList::createImage,
- print_args, char_buffer::do_html, char_buffer::do_image,

- * src/roff/nroff/nroff.sh: Fix straggling use of `$1`, which
- might not have a clear meaning in some shells after being
- shifted (what if we just shifted the last argument?). Also
- `continue` after processing a (groff) option argument, as we
- should make no attempt to parse it.

- * src/roff/troff/input.cpp (do_suppress): Recast diagnostic
- messages for clarity, to communicate in terms of what the
- escape sequence _is_, and to quote literals expected as input.
- * src/roff/troff/node.cpp (suppress_node::tprint): Recast
- diagnostic to prevent misinterpretation of image "description"
- as being HTML IMG tag alt text or something like that.
- Unfortunately, the new language speaks in terms of internal
- implementation details ("grohtml-info"), but at least that way
- it's easier for a user to decide if they care about it.

- [troff]: Avoid using sprintf() with user-controlled format
- string.
-
- * src/preproc/html/pre-html.cpp (makeFileName): Add comment
- noting need for implementation synchrony between this function,
- which generates \O5 escape sequences, and troff's
- suppress_node::tprint member function, which interprets them.
- * src/roff/troff/node.cpp: Rename 2 static globals for clarity.
- - `last_image_filename` -> `image_filename`
- - `last_image_id` -> `subimage_counter`
- (suppress_node::tprint): Set up the buffer for image file name
- to be written using a constant rather than an embedded literal.
- Unconditionally initialize the buffer with a string terminator,
- so there is no chance of a read from uninitialized storage.
- Drop unused code involving `tem`. Drop stale comments. Clarify
- comment: an `image_filename` doesn't _always_ contain a format
- string, only sometimes. Replace use of `sprintf` with manual
- construction of a new image filename string. There are two
- cases, one where a format string {presently "%d"} is present,
- and one where it is not. If it is present, locate it
- {`percent`}. This means a limited/bounded image ("subimage") is
- being processed; increment the subimage counter. Write a new
- image file name preserving the parts before and after "%d" (the
- "prefix" and "suffix", and replacing only the middle, using
- `sprintf` with the subimage counter and the (string literal)
- format. Be mindful of string bounds and memory allocation,
- issuing diagnostics or aborting as necessary. If the image file
- name does _not_ contain a format string, but needs only to be
- copied, do that (`strcpy`), again instead of using `sprintf`.

- [grohtml]: Fix Savannah #60971.
-
- * src/preproc/html/pre-html.cpp (makeFileName): Consistently put
- a dash at the end of `macroset_template` whether the image file
- name stem is user-supplied or the default. Stop adding the dash
- before the image number in `image_template` instead. This makes
- the image file name format reliable whether the image needs to
- be subdivided (eqn) or not (tbl).

- [grohtml]: Reduce noise to standard error stream.
-
- * src/preproc/html/pre-html.cpp (imageList::createImage): Fix
- apparent oversight: `EXE_EXT` was not being applied to the

-
- * src/preproc/html/pre-html.cpp (html_system): Stop sending the

-
-2021-07-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/hpftodit/hpftodit.cpp (show_symset): Prevent
- sprintf() from overunning a static buffer. Thanks to Bjarni
- Ingi Gislason for the report. Resize buffer to be large enough
- to accommodate a 64-bit unsigned int type formatted as decimal.
- Also add assert() before the sprintf() to abort if the int type
- is even larger than that. Use "%u" conversion instead of "%d"
- since the quantity is unsigned.
- (hp_msl_to_ucode_name): Similar, but for a signed int.

-
- * src/roff/nroff/nroff.sh: Slightly refactor. Rename formerly
- unused loop index variable from `i` to `arg` to leverage it in a
- later diagnostic message without a separate definition. Inside
- the loop, expand `arg` instead of positional parameter 1, the
- meaning of which is less obvious after the parameter list is
- shifted by the new `is_option_argument_pending` logic (commit

-
-2021-07-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/number.cpp (parse_term): Tweak diagnostic
- messages. When a left operand to a binary operator is empty,
- report the operator in question (helpful for string
- interpolations in complex expressions). When handling input
- scaling indicators, drop word "this" from "this context", since
- the parser's context might not be clear from a file name and
- line number. Say "scaling indicator" instead of "scale
- indicator".
- (parse_expr, parse_term): Rename function parameter from
- `scale_indicator` to `scaling_indicator`.
-
-2021-07-21 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (define_color): Tweak warning

-
- [nroff]: Pass a supplied `-c` option to groff. While at present
- this does little more than `-P-c` already achieves, that might
- not be true forever. Further, there is a distinction between
- ignoring color-related requests in groff input documents and
- ignoring color-related commands in device-independent output.
- This distinction would make it unwise to adapt `-c` to any other
- purpose in nroff in the future.
-
- * NEWS: Update item from commit dd725dce, 10 February 2020.
- * src/roff/nroff/nroff.sh: Pass `-c` option to groff in addition
- to synthesizing a `-P-c` option (for grotty) when it is seen.
- * src/roff/nroff/nroff.1.man (Options): Document `-c` as an
- option recognized by troff(1).
-

-
- [nroff]: Support space between option flags and their arguments.
-
- * src/roff/nroff/nroff.sh: Add new `is_option_argument_pending`
- flag to add an additional state to the option parser. Set it if
- an argument-requiring option is encountered with no abutting
- argument. If it is set when a new argument is encountered,
- absorb the argument into the groff option list and clear the
- flag. Modernize script in a couple of other ways.
- - Exit with status 2 upon usage errors so that this condition
- is easily distinguished from a groff abort (which exits with
- status 1).
- - Test shell variables for non-nullity with test(1) -n
- operator instead of a string comparison.
- * src/roff/nroff/tests/verbose_option_works.sh: Test correct
- construction of groff command using this input form.
- * src/roff/nroff/nroff.1.man (Options): Add spaces between
- option flags and option arguments. Sync metasyntactic variable
- names with groff(1) while we're at it.
- (Description): Drop sentence warning of whitespace prohibition.
- (Exit status): Add new section.

- has showed up after decades of waiting. Production of the
- original was a Ph.D. thesis. Excited by de Moivre's theorem?
- Take a stab at it.
-
- * src/roff/groff/groff.cpp (main): Comment out effect of `-J`

- attempting to execute a nonexistent preprocessor).
- (synopsis): Add comment reminding us to document the option if
- we ever get the support.
- (help): Comment out documentation of option.

-
- [[gnt]roff]: Make usage messages more accurate.
-
- * src/roff/groff/groff.cpp (synopsis): Drop `-h` and `-v` from
- normal operation synopsis. Sort options in en_US lexicographic
- order. Tighten presentation of alternate usage forms.
- (help): Document longer forms of `-d` and `-r`.
- * src/roff/nroff/nroff.sh: Report `$prog` instead of "nroff"
- literal. Refer to `-P` option argument as "arg" instead of
- "opt", for consistency with groff usage message. Use opposite
- case from option letter for option argument.
- * src/roff/troff/input.cpp (usage): Put brackets around options.
- Sort options in en_US lexicographic order. Drop `-v` from
- normal operation synopsis. Use opposite case from option letter
- for option argument. Put operand name in capitals. Set valid
- usage forms on one physical line each (see 89648fb4, 5 June).
- Add synopsis line for alternate usage forms.

-
- [troff]: Refactor environment initialization, switching, and
- copying.
-
- * src/roff/troff/env.cpp: Rename struct `env_list` to
- `env_list_node` since it describes a node of a singly-linked
- list. Remove constant `NENVIRONMENTS` and array `env_table`.
- Add static symbol `default_environment_name` to replace string
- literal.
- (init_environments): Stop initializing `curenv` through
- `env_table`. Use `default_environment_name` for that
- initialization and add the default environment to
- `env_dictionary`.
- (environment_switch): Simplify. Shorten "dummy environment"
- diagnostic message. Stop creating an integer-named
- environment inside the `env_table` array, only falling through
- to use the `env_dictionary` if the named environment is not a
- valid integer or if the array is full. Instead use
- `env_dictionary` always. Drop no longer needed `pop`
- quasi-Boolean integer with extra state to suppress environment
- stack underflow errors. Instead report the error if underflow
- occurs, regardless of any other circumstance.
- (environment_copy): Simplify. Stop searching the `env_table`
- array for an environment to copy from, only falling through to
- use the `env_dictionary` if the named environment is not a valid
- integer or if the array is full. Instead search
- `env_dictionary` always. Emit "no environment specified to copy
- from" diagnostic only if the `evc` request is given no argument.
- If the source environment to copy from is given but not found,
- emit a new diagnostic naming the nonexistent environment. Fix
- bug: stop returning early if no copying could be done; instead
- fall through to the end of the function, which calls
- `skip_line()` and prevents anything on the remainder of the
- {invalid} control line from being interpreted. Problem dates
- back to commit da3b7137, 6 March 2000 (groff 1.16).

- * tmac/mdoc/doc-syms: Bracket macro definitions tightly with

- assumption. The files in general were also drafted under the
- assumption that they'd be stripped, so `eo` was in effect for
- broad swaths of the file including portions outside of any macro
- definition where comments were used. But comments are expressed
- using the escape character! So we got warnings about an
- undefined '\"' macro, and that was just the beginning of a
- wrecking ball of trouble that smashed through the
- implementation. Some--but not all--string definitions (and
- appendments) needed to be bracketed with `eo` and `ec` as well,
- to delay interpolation of embedded string names that are not
- defined until macros interpolate them later. I did what
- appeared necessary to pass our tests and keep -Tutf8 and -Tps
- renderings of tmac/groff_mdoc.7 from changing from their
- strip-influenced output. Subtle bugs might linger, but some
- won't be the fault of the unstripping process. (For instance,
- try provoking a usage message on the `Hf` macro.)

- * tmac/it.tmac:
- - Revise copyright date to just this year (it had been copied

- - Use grave accents instead of acute ones to indicate stress
- on word-final vowels. Per the University of Wikipedia and a
- sampling of apparently well-typeset Italian language
- documents online, this appears to be correct. Yell at me if
- I'm wrong.
- - Source latin1.tmac instead of latin9.tmac; Italian doesn't
- require any letter code points from Latin-9, unlike the
- French file upon which this one was based, and Latin-1 is
- less of a pain to work with.
- - Set the hyphenation mode to 1 instead of 4 for congruence
- with the requirements of the hyphenation patterns.
- - Set up hyphenation codes. This (and sourcing latin1.tmac)
- might not be necessary as the hyphenation pattern file, of a
- more recent vintage than the others we're using, is pure
- ASCII. However I don't understand these issues perfectly so
- I am making the conservative choice. Again per the
- University of Wikipedia, Italian requires only acute and
- grave accents, in contrast to the rich French diacritical
- bouillabaisse.
- - Set the hyphenation language and load the pattern file.
- - Add comments in parallel with other localization files and
- to supply text editors with hints.

- [grog]: Refactor input parsing.
-
- * src/utils/grog/grog.pl:
- - Add scalar `use_compatibility_mode` (see below).
- - Add list `request` to store the names of all requests
- recognized by groff so that they aren't confused with macro
- names.
- - Add scalars `have_seen_first_macro_call` (replaces
- `before_first_command`, but at global scope),
- `is_continued_line` and `logical_line`. The latter two
- enable us to handle *roff input line continuation correctly.
- (process_arguments): Set `use_compatibility_mode` if `-C`
- option specified.
- (process_input): Refactor to greatly simplify, to not attempt
- to read the first line of an input file as a special case, and
- to avoid sending `do_line` an undefined argument (when EOF is
- reached).
- (do_first_line): Delete.
- (do_line): Rewrite the early stages of input parsing.
- - Concatenate continued input lines, setting
- `is_continued_line` and returning early as each one is seen,
- storing the accumulating input in `logical_line`.
- - Check the input line for the form of comment deposited by
- Perl's Pod::Man, which uses a highly accented dialect of
- man(7); if it's present, inflate `man_score` to compensate
- for the page-private `IX` macro it defines but which
- duplicates the name and function of a 4.2BSD-era ms(7)
- extension that would otherwise deceive our scoring
- mechanism, because Pod::Man produces `IX` calls to
- metastatic excess. (An alternative to this kludge is
- documented in comments: if a "standard" macro is redefined,
- we could delete it from the relevant lists and hashes.)
- - Strip *roff comments from input.
- - Normalize control lines; convert the no-break control
- character to the regular one and remove unnecessary
- white space.
- - Remove brace escapes.
- - Recognize two-character macro calls when not followed by
- white space in compatibility mode.
- - Drop logic that erroneously attempted to infer soelim(1) use
- from macro calls and request invocations. The grog(1) and
- soelim(1) man pages now both explain why such an effort was
- misguided.
- - Recognize macro definitions created by .am and .am1 requests
- {not just .de and .de1}.
- - Ignore all other *roff requests.
- - What remains must be a ("standard") macro call, so set
- `have_seen_first_macro_call`.
-
- * src/utils/grog/grog.1.man (Limitations): Document a further
- restriction: don't change the escape character, either.
-
- * src/utils/grog/tests/smoke-test.sh: Comment out pic-detection
- test on soelim(1). The pic macro calls are guarded by roff
- control structures and only worked previously by accident
- because grog did not recognize *roff input line continuation,
- now it does and the illusion is dispelled. (A reliable way to
- fool grog before and after my refactoring is now documented in
- its man page.)

-
- * src/utils/grog/grog.pl:
- - Drop scalars `groff_opts`, `device`, and `with_warnings`.
- - Move scalar `pdf_with_ligatures`...
- (process_arguments): ...here. Recognize all groff options
- that take an optionally whitespace-separated option argument
- and apply the existing "delayed option" handling to them.
- Push any groff option except `-m` as-is onto the constructed
- groff command's argument list (`-m` handling is unchanged).
- Match long option names exactly, not sloppily. Stop
- recognizing `--warnings` option. Emit error diagnostic if
- unrecognized long option encountered.
- (infer_device): Delete subroutine and its top-level call site.
- (help): Undocument `--warnings`.
-
- * src/utils/grog/grog.1.man:
- (Synopsis): Use font style macros instead of .OP. Undocument
- `--warnings`.
- (Options): Note that the groff arguments produced by the grog
- `--ligatures` option are supported only by the `pdf` device.
- Undocument `--warnings`. Undocument groff-incompatible
- restriction on whitespace before option arguments; grog is
- compatible now. Simplify discussion in light of simplified
- grog logic.
- (Details): Undocument scenario where grog infers multiple
- main/major/full-service macro packages; this no longer
- happens.
- (Examples): Update to no longer illustrate inclusion of `-T
- ps` option; this no longer happens by default.
-
- * NEWS: Document removal of grog's `--warnings` option.
-
- Fixes <https://savannah.gnu.org/bugs/?57873>; groff options are

- (process_arguments): Generalize handling of `-T` and `-m`
- options to permit optional whitespace. Rename scalar `was_T` to
- `delayed_option`.
- (infer_device): Stop unconditionally adding a `-T ps` argument
- to the generated groff command. Remove logic that validates any
- given `-T` option argument; instead, let groff fail if a bad one
- is supplied (its own diagnostics in this scenario were improved
- in commit 5a721a30, 27 May). This makes grog agnostic about any
- differently configured default device in groff itself, and about
- the GROFF_TYPESETTER environment variable.
-

- * src/utils/grog/grog.pl (process_arguments, construct_command):
- Tweak warning diagnostics to use a style where an empty argument
- will be easy to spot.
- (do_first_line): Stop emitting pseudo-diagnostic (to standard
- output!) if we see a "groff options line" [it's not] of
- incorrect form. The preprocessor encoding hint convention of
- concern here is particular to man pages, disregarded by at least
- one major implementation thereof (man-db man), and not used by
- other types of roff documents; at this point, we don't yet know
- if the document we're processing is a man page.
- (construct_command): Correct comment and related logic error.
- Clear the inferred main macro package if _any_ `-m` argument
- matching any main macro package is given. Warn only if what is
- specified doesn't match the inference.

-2021-06-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [grog]: Heavily refactor.
-
- * src/utils/grog/grog.pl:
- - Drop import of unused module `Data::Dumper`.
- - Drop unused scalars `Sp` and `correct_tmac`.
- - Simplify determination of version number. Drop hash `at_at`
- which only stored one key, `GROFF_VERSION`. Initialize
- scalar `groff_version` to "DEVELOPMENT". Rename scalar
- `before_make` to `in_source_tree` and initialize to zero.
- Update `groff_version` with Automake-determined version
- variable if it is defined (i.e., grog is not running outside
- of, or in an unbuilt, groff source or binary distribution).
- - Drop unused `Mparams` list. Replace it with new list
- `requested_package`, which stores the arguments to any grog
- `-m` options specified by the user.
- - Rename many objects so that I, and others, can better
- comprehend their purpose, and for consistent letter casing.
- . @Command -> @command
- . @devices -> @device
- . $Prog -> $program_name
- . %macros -> %user_macro
- . $have_any_valid_args -> $have_any_valid_arguments
- . &handle_args -> &process_arguments

- . &make_groff_tmac_man_ms -> &infer_man_or_ms_package
- . &make_groff_line_rest -> &construct_command
- - Drop many unused keys in `Groff` hash.
- - Add new lists, `macro_ms`, `macro_man`, and
- `macro_man_or_ms` to support new scoring technique to
- disambiguate input documents between these two packages.
- - Append the foregoing 3 lists to new list `standard_macro`,
- and add these as keys to the `Groff` hash.
- - Add new list `main_package` to keep track of full-service
- package names.
- - Add new scalars `man_score`, `ms_score`, and
- `inside_tbl_table` to aid disambiguation of .TH macro calls
- and the many macro names shared between man(7) and ms(7).
- (process_arguments): Strip '-m' off of argument before storing
- the remainder in `@requested_package`.
- (do_line): Detect .TH macro call even if white space occurs
- between the control character and the macro name.
- (do_line): Inflate `$man_score` by 100 if .TH is the first
- macro call seen in a document.
- (do_line): Fix bug; clear `$before_first_command` in correct
- scope--after any macro call, not just if we saw a .TH as the
- first macro call.
- (do_line): Set `$inside_tbl_table` when we see a .TS call.
- (do_line): Clear `$inside_tbl_table` when we see a .TE call.
- Also increment `$Groff{'tbl')' again, increasing the "score"
- of tbl(1) usage evidence.
- (do_line): Drop a lot of code that manually increments %Groff
- keys corresponding to man and ms macros. This is now done
- differently and elsewhere.
- (do_line): Drop "P" from list of characteristic mm(7) macros.
- (do_line): Simplify matching of mom(7) macros (match $command,
- not $line). Extend list of characteristic mom(7) macros.
- (do_line): Increment $Groff{$key} if $key is in
- @standard_macro.
- (infer_man_or_ms_package): Rewrite. Compute a score for each
- package by counting occurrences of their characteristic
- macros. If both have a score of zero, assume that the input
- is a raw roff document. If the scores are equal
- {doc/webpage.ms, startlingly, comes within 1 point of a tied
- score}, infer ms(7) if 'TH' was never called, and if it was,
- issue a diagnostic advising user to supply a disambiguating
- `-m` option. Otherwise, the scores are unequal: infer the
- package of the winner. Set scalar `inferred_main_package`
- instead of pushing `-m` options onto `@m`.
- (infer_macro_packages): Set scalar `inferred_main_package`
- instead of pushing `-m` options onto `@m`. Explicitly return
- 0 if we fall off the end of the function.
- (construct_command): Rewrite handling of -m options. Add new
- list `msupp` to store supplementary (non-main) macro package
- arguments. If a full-service package was explicitly
- requested, it had better not clash with what we inferred. If
- it does, explicitly unset `inferred_main_package` so that the
- -m arguments are placed in the same order that the user gave
- them; caveat dictator. If `--run` option was given, just
- print the command; don't preface it with __FILE__ and __LINE__
- noise.
- - Remove comments documenting shared variables used by
- subroutines. These are far from useless but too tedious to
- keep up to date while the code is in flux.
- - Note several places for further code review or refactoring
- with "XXX" comments.
- - Add Vim modeline.
-
- grog now passes all its tests and correctly infers arguments for
- all in-tree groff documents (except for a known, and already
- documented in grog(1), false positive detection of soelim in
- soelim(1)). This refactor also obviates or resolves several
- outstanding Savannah tickets.
-
- Fixes <https://savannah.gnu.org/bugs/?44707> by obviating it;
- grog no longer cares about file name extensions on man pages (or
- any other input).
-
- Fixes <https://savannah.gnu.org/bugs/?55302>; same. The quality
- of diagnostic messages has been improved as well.
-
- Fixes <https://savannah.gnu.org/bugs/?59753>; same.
-
- Fixes <https://savannah.gnu.org/bugs/?59664>. The attached
- patch was a less aggressive refactor of &do_line and %Groff.
- Its author made the following claim for it: "With this patch,
- all 'man', 'me', 'mom, and 'ms' files in the repository are
- correctly identified. The only example of a 'mm'-file is
- "letter.mm", which is not recognized correctly." As noted
- above, the present refactor achieves correct recognition of all
- of the files, including letter.mm.

-
- [grog]: Revise diagnostic messages.
-
- * src/utils/grog/grog.1.man (err): Rename from this...
- (warn): ...to this. Prefix diagnostic with command name and
- diagnostic severity level. The subroutine didn't change the
- exit status and was not used to report serious trouble, so
- "warning" seems appropriate.
- (make_groff_tmac_man_ms): Update call sites. Modify diagnostic
- wording to stop calling macros "requests".

-
- * src/utils/grog/grog.1.man (Limitations): Add subsection

- groff's -s option as one that can be inferred, because at
- present it cannot be.
-
- Prompted by Savannah #60421.

-
-2021-06-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Assigning Formats): Revise discussion.
- Clarify that a format never causes truncation of an interpolated
- magnitude. Note that non-Arabic number formats cannot be used
- as operands to arithmetic expressions. Add example of how to
- work around this.
-
-2021-06-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Clarify diagnostics.
-
- * src/roff/troff/reg.cpp (reg::set_increment): Update diagnostic
- to unabbreviate "auto".
- (reg::alter_format): Update diagnostic to say "assign" instead
- of "alter", since the documentation consistently uses the former
- term.
-
-2021-06-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Slightly refactor. Make the source code slightly more
- accessible by using a `bool` type for a member function's
- default parameter used as a Boolean, and comment it at call
- sites where the default is overridden.
-
- * src/roff/troff/token.h (token::get_char): Change type of
- parameter from `int` to `bool` and default from 0 to `false`.
- * src/roff/troff/input.cpp (token::get_char): Update definition.
- * src/roff/troff/env.cpp (hyphen_word):

- comment indicating meaning of parameter.
-
-2021-06-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac (TH): When outputting HTML, write the
- possibly case-transformed (but not yet abbreviated) page title
- as the `title` element instead of the unaltered first argument
- to `TH`.
-
-2021-06-25 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac (an-abbreviate-title): Define with `de`, not
- `de1`, since it is not intended for call by traps or users.
-
-2021-06-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Tab Stops): Fix erroneous claim; tab stops are
- not set "every half inch across the page". This is only true in
- "line tabs mode", which is not enabled by default. The default
- behavior, to keep compatibility with AT&T troff, measures tab
- stops relative to the current position on the input line.
-
-2021-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/mdoc/doc-nroff-u: Set the usekeeps register used by tbl
- to the logical complement of the cR (continuous rendering)
- register. This prevents blank lines from creeping into tables
- in that mode.
-
-2021-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac (an-blank-line-trap, an-leading-space-trap):
- We say in a comment, "Macros ... that are called by traps of any
- kind must be defined with `de1` because they might be called
- from a context where compatibility mode is enabled." So do it.

-
-2021-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac (an-write-paragraph-tag): Lightly refactor

- `ie`/`el` structure.
-
-2021-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac: Rename `an-HF-remap-I-style` register to
- `an-remap-I-style-in-headings` for greater clarity.
-
-2021-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/mdoc/doc-common-u (doc-header, doc-end-macro): Partially
- revert bf4b3dde (from 20 May); per Ingo Schwarze, continuous
- rendering in mdoc(7) documents has always used only one vee
- between headers, footers, and man page body text.
-
-2021-06-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/en.tmac: Stop using `do` request; it's unnecessary since
- the file is already loaded with compatibility mode off.
-
-2021-06-18 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [ms]: Fix doc omission; .ID can take an argument.
-
- * doc/groff.texi (ms Document Control Settings) <DI>:
- Characterize register setting as a _default_.
- (ms Displays and Keeps): Add optional variable "indent" argument
- to syntax summary of ".DS I" and ".ID". Note that the given
- indentation is used if present, and \n[DI] otherwise.
- * doc/ms.ms (Displays and keeps): Add optional variable "indent"
- argument to syntax summary of ".ID". Switch fonts more
- carefully and apply italic corrections.

- for groff (and not throw warnings of type 'mac').
-
-2021-06-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/doc.am: Improve diagnostics during documentation
- generation; none should occur normally, but when they do, seeing
- troff complain about "<standard input>" is disheartening.
- (DOC_GROFF_ONLY): Add -b option so we get backtraces (also kill
- off trailing whitespace).
- (DOC_GROFF):
- (doc/pic.html):
- (doc/webpage.html): Add sed expression to inject `lf` request

-
-2021-06-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/me-revisions: Add 'me' macro package revision log, scraped

-
-2021-06-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/e.tmac-u: Rename registers for clarity. Unlike other
- macro packages supplied by groff, "me" mostly remains within the
- AT&T 2-character name space, accessing extended names
- selectively through `do` and `de1` requests. The package
- therefore has no characteristic name prefix.
- need_eo_h -> devtag-needs-end-of-heading
- need_eo_tl -> devtag-needs-end-of-title
- need_tl -> devtag-needs-title
- (@html_check_need_title, sh, EQ): The foregoing registers are
- effectively Booleans, so perform Boolean-style tests on their
- interpolations.

- Fixes a second third of <https://savannah.gnu.org/bugs/?42515>.
-
-2021-06-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/e.tmac-u: Work in compatibility mode. It seems this was
- the intention (reasonable, since "me" originates in pre-groff
- BSD Unix), but there were several problems.
- (@R): Prefix register existence test with `do`.
- (@html_check_need_title): Define with `do` since the macro name
- is long, and also with `de1` so that we can freely use groff
- extensions within. Drop many `do` requests from macro
- definition.
- (@check_need_title): Define with `do`, as above. Add comment
- explaining why `de1` is not needed for this macro definition.
- (@S): Prefix macro/string existence test with `do`. Remove
- spurious space so that the argument string name is truly defined
- as empty.
- (nm, n1, n2): Prefix handling of long register names `_#p` and
- `_#f` with `do` request.
- (top level): Prefix `mso` request with `do`.
- ((x-html): Define with `do` and `de1` instead of `de`. Drop
- now-unnecessary `do` requests from macro body.
- ()x-html): Define with `do` and `de1` instead of `de` for
- symmetry.
- (xp-html): Define with `do` and `de1` instead of `de`. Drop
- now-unnecessary `do` requests from macro body.

- `an-devtag-needs-second-column`.
- (an-input-trap, SH, SS, HP, (initialization)): Do it.

-
-2021-06-16 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac (an-end, an-header): In continuous rendering

- Schwarze for the suggestion.
-

- (LP, PP): Make these aliases of P.
-
-2021-06-16 G. Branden Robinson <g.branden.robinson@gmail.com>

- [man]: Don't spuriously break a page after a paragraph tag when
- the tag is short enough to fit within the paragraph's
- indentation.
-
- * tmac/an-old.tmac (an-write-paragraph-tag): Reserve ("need") 2
- vees plus 1 basic unit of vertical space regardless of the width
- of the tag. In the short tag case, we reverse space by one vee
- after outputting the diversion in which the tag is stored, but
- it will always contain a break, and by the time we reverse, we
- might have already hit a page location trap
- {an-break-body-text}, and by then it's too late to back up.

-
- Indent an IP paragraph based on the type size of the paragraph
- text, not a preceding heading. We have to delay evaluating IP's
- argument until the font size has been reset, which I've
- attempted to do by simply passing the argument unevaluated down
- the call hierarchy, instead of saving it in a number register
- right away, as appears customary in this ms implementation.
-
- However, par@reset is called from a great number of places, and
- these usually set the indent registers beforehand. I've left
- this as it is, so now two ways of setting the indents exist: via
- register and optionally via argument.
-
- * tmac/s.tmac (par@reset): Move font-size setting stuff before
- indent-setting stuff; set registers from optional arguments with
- default "n" scaling indicator before setting indents.
- (par*start, par@finish): Don't set registers, but instead pass
- arguments to par@reset.
- (@IP): Pass argument unevaluated to par*start.

- Refactor grog even more aggressively. Make the tedious search
- for subs.pl unnecessary by inlining it into grog.pl directly.
- This makes the script stand alone and much more convenient to
- work with, and doesn't contribute to bloat, in my
- opinion--subs.pl was 10 times the size of grog.pl, and most of
- the code in the latter was dedicated to trying to locate
- subs.pl.
-
- * Makefile.am: Delete references to $(grog_dir).
- * configure.ac: Delete call of `GROFF_GROGDIR_DEFAULT` macro.
- * m4/groff.m4: Delete definition of same.
- * src/roff/grog/grog.am (GROG, dist_grog_DATA, grogdir): Drop

- expression replacing `@grog_dir@` with `$(grog_dir)` in grog.pl.
- * src/roff/grog/grog.pl: Inline most of subs.pl (except for

-
-2021-06-05 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/groff/groff.cpp: Revise usage message.
- (synopsis): Set primary synopsis on a single output line, for
- convenience of parsing and also because we have no control over
- the width of the program name in character cells; it comes from
- argv[0] and is under user control. There is thus no point in
- trying to get pretty formatting. Also include separate synopsis
- lines for short and long help options. Use opposite case from
- option flags for option arguments.
- (help): Collate option flags in English lexicographic order.
- Include space after flag letters for options that take
- arguments. Consistently use capitals for option arguments
- because they are space-separated here. Illustrate longer forms
- of -d and -r options. Update language (some, like "tmac.name",
- was very old). Add reference to groff(1) man page at end.
- (usage): Drop appendnment of notice regarding -h option; this is
- now covered in `synopsis()` unconditionally.

- to reduce the length of a man page title (i.e., the "ls" in
- "ls(1)", if it is too wide to fit in the page header (and would
- overwrite the center header material, usually the title of the
- manual section). Since the beginning and end of the title might
- be important for disambiguation, truncation at either end would
- be unwise; replace the middle of the title with an ellipsis.
- Define new an-pageref and an-title-abbv strings for use by other
- macros and user-defined PT and BT traps.
- (PT, an-footer): Use new an-pageref string for economy.
- (an-header): Call an-abbreviate-title after setting the title

- surprising rendering; enabled if the CHECKSTYLE register is
- greater than 2.
-
- * tmac/an-old.tmac (an-blank-line-trap, an-leading-space-trap):
- Issue style warning if enabled (and only if fill mode enabled in

- (TH): Install traps.
-
- * doc/andoc.tmac (reload-doc): Remove man(7) traps before

-
- * man/groff.7.man (Requests/Request short reference) <.ta>:
- Describe the request as tersely as possible without omitting its
- essential syntax and semantics. (The AT&T troff "+" relative
- prefix for normally absolute positions ".ta 1i +1i +1i" and

-
- * tmac/groff_www.7.man: Stop using the "www" macro package. The
- macros it exposes are not part of the quasi-standardized man(7)
- language, and thus should not be used in man(7) documents. See
- groff_man_style(7) for portability advice. Besides, the
- extension macros in the permissively-licensed an-ext.tmac are
- sufficient to support URL and email hyperlinks, and our SH and
- SS macro implementations already support anchor placement
- without requiring explicit effort from page authors.
- (initialization): Stop sourcing www.tmac. Stop calling .LK and
- .HR; the page-internal navigation links were being placed after
- the apropos line instead of at the beginning of the page,
- contradicting the comment that was there (possibly a bug).
- (Requests) <URL, LK>: Stop calling .TAG.
- <LK>: Drop paragraph advising reader to format page for groff's
- HTML output device to observe the navigation links at that point
- in the test.
-
-2021-05-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Comments): Fix error in description of parser
- operation; '.\"' is an effective whole-line comment not because
- it is a call of an undefined macro named '\"' (no 'mac' warning
- is emitted when that warning type is enabled), but because the
- comment escape is recognized normally and what remains is
- handled as the empty request. Clarify that the optional
- argument to the .ig request is the name of a macro (which will
- be called normally _and_ end the ignored region; this is
- analogous to ".de foo bar").

-
- * tmac/an-ext.tmac (UR, UE, MT, ME): Rename environment and

-2021-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Copy Mode): Fix omissions from list of escape
- sequences interpreted even in copy mode. Add \g, \V, "\.",

- groff(7) now. Add cross reference to "Character Translations"

-
-2021-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>

- [man]: Slightly refactor footer spacing management when
- continuously rendering.
-
- * tmac/an-old.tmac (an-end): Increase the page length _after_
- flushing a pending output line. Do so only by the amount of
- spacing we actually perform next. Make the scaling indicator on
- the .sp request explicit. The amount seemed magical because it
- was accounting for the one line to be consumed by output of the
- footer title line. Instead, move that further increase of the
- page length from here...
- (an-footer): ...to here (~250 lines away), before calling BT.
-
-2021-05-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/mdoc/doc-common-u (doc-end-macro): When continuously
- rendering and after flushing the last line of the body text of a
- page, vertically space by 3 vees instead of 1, for consistency
- with our man(7) implementation. Also increase page length by
- same amount _after_ flushing a pending output line, for symmetry
- with other spacing requests (and to prevent nasty surprises
- analogous to those in Savannah #60611).
- (doc-header): Put 3 vees of space after the header in continuous
- rendering mode, not 1 (and increase page length accordingly).

- after finishing the only document we render.

-
- [man]: Fix stochastic vertical space loss problems in continuous
- rendering mode by being more scrupulous about extending the page
- length. As noted in Savannah #60611, sometimes the vertical
- space between a header line and the first section heading
- {"Name"} would be reduced or removed altogether, in a way that
- was highly sensitive to circumstances. As far as I can tell,
- the problem is that this vertical space disappeared only when we
- were in double-secret probation no-space mode; this is the
- special non-spacing mode {not apparent with inspection of
- \n[.ns]} that happens when the stealth internal page location
- trap is sprung. This trap does not appear in .ptr output but
- can be disabled with ".vpt 0", which is an alternative fix for
- this problem {because continuous rendering mode does not use
- vertical position traps at all}. Another fix might have been to
- simply call the moral equivalent of ".pl MAXINT" as soon as
- continuous rendering mode was decided upon.
-
- * tmac/an-old.tmac (an-header): In continuous rendering mode,
- extend the page length by one line before calling PT to output
- the page header, and afterwards, extend the page length by 3
- vees and space by that amount (instead of half an inch).

-
- * tmac/an-old.tmac (an-footer): Improve symmetry with an-header.
- If rendering to HTML, don't bother setting the

- values; instead don't call BT, just as we don't call PT in

-
-2021-05-18 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac: Refactor alternating font macros. These
- macros are hard enough to understand without adding gratuitous
- structural differences to the reader's burden. Make their
- implementations rigidly parallel. Update comments.
- (RI, IR, IB, BI, RB, BR): Always define the `an-result` string
- as empty except for a dummy character '\&' for the sake of
- compatibility mode.
- (RI, IR, IB, BI): Defer interpolation of the first argument to
- the while loop if there are at least two (like the existing RB,
- BR). This way the style name arguments to the font selection
- escape sequences in the appendment to `an-result` match the
- order of the letters in the macro name (useful to make sense of
- diffs).
- (RI, IR, IB, BI, RB, BR): Always remove the `an-result` string
- after interpolating it.
- (RB, BR): Only do work if there are any arguments.

-
- [man]: Ignore FT register when appropriate.
-
- * tmac/an-old.tmac (initialization): Validate user-specified
- value of \n[FT]. Continuous rendering ignores FT (page location
- traps are not used for footers in that mode). Measuring a
- footer distance from the page top isn't done. A footer distance
- of over half the page length is unlikely. A footer distance of
- less than one line height is too. Issue diagnostics in all of

- schedule a break in the page text prior to spacing down to the
- footer) at twice the value of \n[FT], not a hard-coded -1i.
- This way, the user can't make the an-p-footer trap (planted at

-
- [man]: Fix missing page footers when continuously rendering
- multiple documents. Resolving this uncovered entangled header
- and footer management bugs with batch processing even when _not_
- continuously rendering.
-
- * tmac/an-old.tmac (an-start-new-document): New macro clears
- header trap so it doesn't get called with stale information.
- {The TH macro already replants a header trap with every man
- page if not continuously rendering.} This macro also absorbs
- the break-page and page number incrementation logic from TH.
- (TH): Adapt semantics of "an-first" register to mean not "first
- page rendered" (apparently) but "first page of new document".
- If we are _not_ on the first page of a new document and the TH
- macro is called, we must be batch processing: force the previous
- man page to end (call an-end if continuously rendering, or
- an-start-new-document if not). After all the header and footer
- strings have been configured for the man page, call an-header if
- we're on the first page of the document, not (just) if we're
- continuously rendering. Zero an-first register at end of macro
- here unconditionally instead of conditionally in .an-header.
- (an-header): Drop conditional on continuous rendering.
-
- When I batch-render our 62 man pages to the terminal, I do note
- one cosmetic regression: the lj4_font(5) page, when continuously
- rendered in batch processing, has no space between its header
- line and first section heading ("Name"). Another cosmetic issue
- in this scenario is that the footers for every rendered page but
- the last, which had (wrongly) been absent entirely, are set with
- no space after them and the header of the next.
-
- * tmac/tests/an-old_page-footers-present.sh:
- * tmac/tests/an-old_page-header-has-current-data.sh: Add man

-
-2021-05-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac (initialization): Key the reprocessing guard
- {like a C language #include guard} on the existence of the TH
- macro instead of RI. The latter seemed kind of random and TH
- is even more guaranteed to exist; it is the macro name most
- characteristic of the man(7) language and the andoc.tmac
- superstructure relies on it. (TH may have been avoided because
- of its use with tbl(1); however, neither man(7) nor mdoc(7)
- support tbl's TH feature, and GNU tbl does not supply its own
- empty fallback definition as it does for TS and TE. If we ever
- want TH-like functionality in future man pages, I suggest we
- pick a new, non-colliding name for it.)
- (initialization): Relocate load of devtag package; we don't
- need it before entering compatibility mode. Move assignment of
- format of an-page-letter register from a "loose declaration"
- amid macro definitions to within existence test of X register.
- Stop initializing an-extra[123] strings outside of any macro;
- they need to be reinitialized at every TH call when batch
- rendering.
- (TH): Call DT in a less surprising place.
- (TH): Initialize all header/footer-related strings before
- calling header macros, even those not needed for the default
- header configuration.
- (TH): Add style warnings for underspecified arguments.
- (an-ne): Rename register from "an-need", which is pretty
- confusing in context, to "an-amount", since (1) a (vertical)
- amount is what it is, and (2) it's only used within this macro.
- Also due to factor (2), remove the register after using it.

- when URW fonts are not found. Replace dead URL with working
- one. Try to hedge against the future, but the Web is an
- ephemeral place, as are the file names Artifex gives to its
- fonts. Thanks to T. Kurt Bond and Thomas Dupond for reporting
- and investigating the problem.

-
- * tmac/andoc.tmac (reload-man): Delete no-op line that attempts
- to restore compatibility mode. Individual pages have to do
- this, and ".do cp \n(.C" is not effective for the reason
- discussed in the 2020-04-16 ChangeLog entry.
-

-
- * tmac/s.tmac (@RT): Delete definition; make it an alias for
- par@finish. Until commit 021ba0e7 (1 May), they had identical
- definitions. I find it difficult to imagine what use it would
- be to have an undocumented reset macro that resets everything
- _except_ the deeply internal \n[.ev]:ai.

-
- [man]: Handle HF strings with an embedded font family when
- applying italic-to-bold-italic remapping; the feature now works
- on troff devices as well.
-
- * tmac/an-old.tmac (initialization): Do more validity checking.
- Store heading family in new string \*[an-heading-family]. Clean
- up after self.
- (SH, SS): Include the heading family in the remapping target.

-2021-05-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * man/groff_char.7.man (Glyph tables/Mathematical symbols): Fix
- errors in special character descriptions; \[sqrt] is a "special"
- glyph (that is, it uses mathematical metrics on typesetter
- devices), and \[radicalex) is not (and is thus a "text" glyph).
- See Werner Lemberg's ChangeLog entry of 2003-01-05. Problem
- dates to 07a6233ad, 27 May 2014.
-
- The overloaded use of the word "special" really pinches here.
-
-2021-05-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/tty.tmac: Replace fallback glyphs for radical extension
- and square root extension; use \[rn] instead, which works fine.
-
- Now the only glyph in the page that doesn't render on a UTF-8
- terminal (if one's font has adequate coverage) is the Bell
- System logo.
-

-
- [man]: If \*[HF] is a bold style, substitute bold italics for
- italics in section and subsection headings, keeping the font
- weight consistent.
-
- * tmac/an-old.tmac (initialization): Set a flag for this based
- on the interpolation of \*[HF] matching "B" as its last

- * doc/groff.texi: Delete redefinition of \putwordAppendix
- Texinfo macro. This restores the word "Appendix" to the names
- of all appendices and fixes two bad internal links to Appendix
- E, the Register Index, in the DVI and PDF output formats. Per
- consultation with Texinfo maintainer Gavin Smith, it's difficult
- to get the behavior we want, so give up trying for now.

- since it is documented in Lesk 1978 we're stuck with it. Advise
- users to stick with %. Also warn them of the hoop they must

- footnote numbers in nroff mode, inspired by Heirloom Doctools
- ms; since superscripting is not universally available on
- terminals, surround number with square brackets instead.
- (fn@init): New macro finishes initializing footnote module,
- setting up aliases to par@sup-{start,end} strings in troff mode
- and otherwise defining fn@sup-{start,end} as brackets. Define *
- string here, using new strings.
- (par): Call fn@init after par@sup-{start,end} are defined, and

- * test-groff.in: Stop passing the built groff executable -b and
- -ww options by default. This reverses a change from 2017. Dave
- Kemper has convincingly argued that there's no way to override
- -b and turn backtraces on warnings/errors back off, and that the
- built groff should behave as much like a "normal" one as
- possible. The latter factor is of added importance now that we
- are using test-groff for generation of documents.

-2021-04-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/s.tmac (BX): Add alternative implementation for terminal
- {nroff} devices. Store width of boxed text, adding .4m only on
- troff devices (to make room for the vertical box lines). Break
- long input line in troff implementation. If not in troff mode,
- use ISO 6429 color escapes to render boxed text in black on
- white. Use the \Z escape to match breaking semantics of macro
- in troff mode.

-
- * tmac/s.tmac: Make the FAM string work more sensibly; it now
- applies to headers, footers, and footnotes only if set
- before the first call of a sectioning, paragraphing, or
- {non-date} document description macro.
- (PT, BT): Set the font family to that saved for titles.
- (fn*do-FS): Set the font family to that saved for footnotes.
- (par@init): Copy the document font family to independent strings
- for titles and footnotes.

- groff mailing list. Thanks, Hans!
-
-2021-04-17 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/an-old.tmac (SH): Fix apparent thinko. Pass the devtags
- macro a literal "1" argument. Passing it \n[an-level] wasn't
- correct (it stores the relative inset level, not a sectioning
- level), and was useless anyway: SH has already called
- .an-set-margin by this point, which resets \n[an-level] to 1.
- man(7) does not support nesting of SH macros. Also call
- .DEVTAG-NH by its alias .DEVTAG-SH since section headings are
- not numbered in man(7).

- ASCII.
- * tmac/fr.tmac: Tell Vim file is "iso-8859-15" (ISO Latin-9).

- Vim users may need to use ":e ++enc=iso-8859-2", for instance,
- to see correct glyphs.

-
- * doc/groff.texi (Manipulating Hyphenation):
- * man/groff.7.man (Hyphenation):
- * man/groff_diff.7.man (Implementation differences): Refer to
- "U.S. English" hyphenation patterns as simply "English"; they
- will be mostly correct for Commonwealth English as well, and no
- alternative English hyphenation patterns for other territories
- are available.
-
- * doc/groff.texi (Manipulating Hyphenation):
- * man/groff_diff.7.man (New requests): Note that default
- hyphenation mode depends on the language used on the system.
- Add concept index entry for localization. Add file index
- entries for the locale macro files (cs.tmac, etc.). Update to
- reflect rename of English hyphenation patterns and .hla
- identifier from "us" to "en".
-
- * src/roff/groff/tests/localization_works.sh: Add 10 test cases.

-
- Implement new .soquiet and .msoquiet requests.
-
- Needed for two planned developments: {1} the i18n patch in
- Savannah #59814 can use this to quietly attempt to open a
- localization file. groff only supports a few locales, so people
- with LANG=es_ES, for instance, would ordinarily see warning
- diagnostics on every groff startup; and {2} system- or
- site-configurable support of per-user {.,}troffrc or man.local
- files, gracefully failing if they don't exist.
-
- * src/roff/troff/input.cpp:
- (do_source): Add new function, taking boolean "quietly"
- parameter and absorbing function of source(), with added
- conditional.
- (source): Convert into a wrapper to call do_source() unquietly.
- (source_quietly): Wrap do_source(), quietly.
- (do_macro_source, macro_source, macro_source_quietly): Analogous
- to the foregoing.
- (init_requests): Hook "msoquiet" to macro_source_quietly() and
- "soquiet" to "source_quietly().
-
- * doc/groff.texi (I/O):
- * man/groff.7.man (Requests/Request short reference):

- (ms Footnotes) <*>: Describe string operation in more detail.
- <FS>: Describe more precisely how the optional argument is

-
- * doc/groff.texi (Manipulating Hyphenation):
- Recast introductory paragraph to better distinguish the
- automatic breaking of words and placement of hyphens at
- user-specified hyphenation points (done with the \% escape) and
- automatic determination of hyphenation points within words (what
- the pattern files and most of the hyphenation mode parameters
- are for). Clarify that what our manual calls "automatic
- hyphenation" pertains only to the latter.
- <hw> Correct over-general claim; hyphenation exceptions defined
- with the .hw request _do_ honor .hy value 2 (don't break a word
- at the bottom of a page), but none of the others.
- <\%> Recast description of escape to emphasize independence of
- its two uses (e.g., "\%pseudo\%unununium" is hyphenated only
- after "pseudo-", if at all).
- <\:> Clarify that escape is an input word boundary.
- <shc> Clarify that the soft hyphen glyph is applied to manual as
- well as automatically-determined hyphenation points.
- <hy> Recharacterize as setting the _automatic_ hyphenation mode.
- Note that restrictions apart from value 2 are not applied to
- words with manually-assigned hyphenation points.
- <nh> Note that request affects only automatic hyphenation.
-
- * man/groff.7.man (Requests/Request short reference) <.hy,.nh>:
- Clarify that requests deal with _automatic_ hyphenation.
- (Registers/Read-only registers) <.hy>:
- Clarify that register applies to _automatic_ hyphenation.
- (Hyphenation): Add new introductory paragraph summarizing manual
- hyphenation support and features, including notice that breaking
- at explicit hyphens is performed in fill mode, i.e., even if
- _automatic_ hyphenation is disabled.

- * man/groff_diff.7.man (Language/Extended requests): Fix
- incorrect claim that additional inter-sentence space is applied
- only in fill mode. Drop word "parameter" from description of
- unit used in .ss request arguments; it is a needlessly specific
- reference to the font file format. Tighten wording.
-
- * man/groff.7.man (Control Characters): Fix incorrect claim that
- end-of-sentence detection is attempted only in fill mode. Note
- that .ss request also affects inter-word spacing.
-
- * man/groff_diff.7.man (Language/Extended requests):

- * tmac/s.tmac: Improve diagnostic messages.
- (@diag): New macro wraps .tm request, always prefixing it with
- the name of the macro package, as well as file and line
- indicators only if these are set to non-empty or non-zero
- values, respectively.
- (@error, @warning): Call @diag instead of .tm directly.
- (@fatal): Retire; it had only one call site and it would have
- greatly complicated @diag to support calling .ab instead of .tm.
- An ugly alternative would have been to call .ab with a redundant
- message after calling @diag.
- (@divert): New macro wraps .di request, remembering the name of
- the current file (\n[.F]) when a diversion is started.
- (@error-recover): Call .ab instead of (deleted) @fatal.
- (pg@super-eject): Tell user what the last file name seen was
- when recovering from an unfinished diversion when processing
- ends.

-
- Fix bug where having line numbering off but the output line
- number register \n[ln] set to a positive value would cause
- tbl(1) table rows to spontaneously become numbered. Use new
- \n[.nm] register to determine whether line numbering is enabled.
-
- * src/preproc/tbl/table.cpp (table::init_output, table::do_row)
- (table::do_bottom): Predicate all conditions on \n[ln]
- additionally on \n[.nm].

-
- Implement new read-only register ".nm". It reports the
- enablement status of output line numbering (caused by the .nm
- request) irrespective of the temporary suspension of numbering
- with the .nn request. Needed because there was no way to
- introspect its state, tbl(1) needs to do so, and the writable
- line number register \n[ln] is not a reliable proxy for it.

- * src/libs/libgroff/searchpath.cpp (search_path::open_file)
- (search_path::open_file_cautious): Save errno before calling
- free() and restore it afterwards. A future version of POSIX
- will require that free() not change errno if it succeeds[1];
- some C library implementations, including recent versions of
- glibc[2], lack this property. free() is called in these
- libgroff functions to clean up after an unsuccessful fopen() of
- a heap-allocated file name string, and because the errno from
- fopen() may be passed to strerror() in a diagnostic message, it
- needs to be accurate. I checked the rest of groff's codebase
- and found no other instances of free() being used to clean up
- after fopen() failure.

- macro (confusingly called "3init"), which is called before

- * contrib/glilypond/glilypond.pl:
- * contrib/gperl/gperl.pl:
- * contrib/gpinyin/gpinyin.pl:
- * tmac/hyphenex.pl: Avoid Perl's unsafe "<>" operator.
-
- The "<>" operator is implemented using the two-argument form of
- "open", which interprets magic such as pipe characters, allowing
- execution of arbitrary commands which is unlikely to be
- expected. Perl >= 5.22 has a "<<>>" operator which avoids this,
- but also forbids the use of "-" to mean the standard input,
- which is a facility that the affected groff programs document.
-
- ARGV::readonly would probably also fix this, but I fundamentally
- dislike the approach of escaping data in preparation for a
- language facility to unescape it, especially when the required
- escaping is as non-obvious as it is here. (For the same reason,
- I prefer to use subprocess invocation facilities that allow
- passing the argument list as a list rather than as a string to
- be interpreted by the shell.) So I've abandoned this dubious
- convenience and changed the affected programs to iterate over
- command-line arguments manually using the three-argument form of
- open.
-
- glilypond doesn't need the initial unshift since that's already
- handled in contrib/glilypond/args.pl.

-
- Document use of SOURCE_DATE_EPOCH and TZ.
-
- The semantics of SOURCE_DATE_EPOCH to groff were not established
- with respect to time zone selection, prompting divergent
- interpretations; Debian and distributions derived from it have
- for several years patched groff to implicitly use UTC as the
- time zone when interpreting the current time (or
- SOURCE_DATE_EPOCH) as a local time. While a convenient and
- defensible choice for reproducible build efforts[1], it runs
- against the grain of user expectations. Systems programmers
- like monotonically increasing clocks; the broader user base
- usually prefers a clock that follows an applicable civil
- calendar. To the latter audience, a difference between
- $ date "+%Y-%M-%d %H:%m:%S"
- and
- $ groff <<EOF
- .af year 0000
- .af mo 00
- .af dy 00
- .af hours 00
- .af minutes 00
- .af seconds 00
- .tm \n[year]-\n[mo]-\n[dy] \n[hours]:\n[minutes]:\n[seconds]

- [ms]: Set footnote line length to AT&T default.
-
- groff ms has since its initial implementation used a default
- footnote line length of 5/6ths of the text line length; this may
- correspond to an early AT&T ms default (perhaps documented in
- the 1974 version of the M. E. Lesk paper, "Typing Documents on
- the UNIX System"[1]). However, as early as V6 Unix (1975), AT&T
- ms actually used a footnote line length of 11/12ths of the text
- line length instead[2].
-

- Thanks to Bjarni Ingi Gislason for reporting the diagnostic
- arising in real life, and to Peter Schaffter for the discussion
- and recommendation. Some bike sheds get painted quickly!

- * src/utils/xtotroff/xtotroff.c (MapFont): Avoid writing past
- the end of a static buffer. Problem found and patch supplied by
- Bjarni Ingi Gislason. I tweaked it to comment it differently
- {in case the buffer ever needs to grow, but the prospects of
- future X11 server-side font rendering development seem dim} and
- use snprintf() instead of retaining the existing sprintf().

- marks. Put each message on one line only.
-
-2020-11-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Parameters): Fix error in example. Arguments

- Location Traps" and "Diversion Traps" under new subsection node
- "Vertical Position Traps" to make the conceptual organization
- more clear. Define and discuss trap visibility earlier.
- Document unit used for page location trap reporting. Introduce
- analogy of .wh and .ch requests as queue operations. Document
- what happens when the same macro is planted as a trap in
- multiple locations; supply example. Supply example of .itc

-
- * tmac/groff_mdoc.7.man
- (Formatting with groff, troff, and nroff): Document what

- Measure the string before and after calling .substring on it,
- and break out of loop if it didn't get shorter.

-
- * src/roff/troff/div.cpp (top_level_diversion::change_trap):
- Emit error diagnostic if an attempt is made to move an unplanted
- macro. This could have been a warning, as it's pretty harmless
- {though possibly a big surprise to anyone who was wondering why
- their .ch was a no-op}, but there's no good warning category for
- this kind of problem and I am not about to start a bike shed
- discussion about it right now.
-
-2020-11-15 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi: Update. Add introductory material. Rewrite
- the first section of the "gtroff Reference" chapter of our
- Texinfo manual. It is written as an introduction for readers
- who want to go straight to "raw" troff without knowing much or
- anything about existing macro packages. Thanks to Dave Kemper
- and John Gardner for feedback and support.
-
- Clarify whitespace usage. "Whitespace" is defined in this
- manual as "spaces, tabs, and newlines". Say only "spaces and
- tabs" when newlines should not be included.
-
- Rename "Font Files" to "Device and Font Files".
-
- Rename "Manipulating Filling and Adjusting" to "Manipulating
- Filling and Adjustment".
-
- Update discussion of "copy mode". Rename from "copy-in mode",
- which I don't think eludicdated anything; is there a "copy-out
- mode"? Rename nodes accordingly. Attempt to explain more
- clearly. Recast to shift emphasis to what _isn't_ merely copied
- in copy mode, since that is what seems to cause confusion among
- the inexperienced.
-
- Update "Conditionals and Loops". Add introductory paragraph.
- Add nodes/subsections "if-then" and "Conditional Blocks". Add
- subsection "Conditional Blocks" to explain the behavior of the
- \{ and \} escapes much more precisely. I don't think this
- syntactical area is well understood. Supply examples.
-
-2020-11-14 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Add style checks to man(7) macro package.
-
- Not otherwise documented yet; experimental--subject to change.
-
- * tmac/an-old.tmac: Initialize CHECKSTYLE to false if not
- already set.
- (an-style-warn): New macro emits diagnostic of type "style" when
- called if CHECKSTYLE register is true.
- (TH): Call an-style-warn if fewer than two or more than five
- arguments are seen.
- (RI, IR, IB, BI, RB, BR): Call an-style-warn if fewer than two
- arguments are seen.
-
-2020-11-11 Bertrand Garrigues <bertrand.garrigues@laposte.net>
-
- Update copyright.

- them empty or zero if they are not set). This reserves them so
- that they don't become used for divergent purposes. man(1)
- programs set these and other parameters already handled (like

- * tmac/s.tmac: Implement \*< and \*> strings for subscripting.

-
- * tmac/s.tmac: Revise diagnostic messages. Define a common

- Continues the long process of fixing Savannah #52463. Drop the
- word "macro" from diagnostic since this will now be clear from
- the prefix. Prefix every macro name in a diagnostic message
- with a leading dot; this was already done in four cases.
- (cov*first-page-init): Use temporary string to avoid multi-line
- diagnostic message.
- (@NH): Use temporary string to prevent overlength line.
-
- A further benefit of this revision is that index information
- produced by ms's .IX macro (which writes to the standard error
- stream) will now be trivially easy to extract even for documents
- that cause diagnostic messages. One can simply filter them with
- grep -v '^s\.tmac:'
- or similar.

-
- Fix ms .TC macro by allowing it to actually use lowercase Roman
- numerals for the page(s) of the table of contents when a custom
- title (header or footer) is defined containing '%'.
-
- As a side effect, eliminate the PN register, which was
- apparently misused because it was undocumented and had a name
- just long enough to be both suggestive and ambiguous. Another
- pin goes into my Ken Thompson voodoo doll.
-
- * tmac/s.tmac (IX): Write out page number of index term(s) using
- the % register (instead of PN), obtaining whatever format is
- assigned to the register at that time.
- (CH): Similarly, output %, not PN, in the center of the default
- heading.
- (PT): Save the format of %, set it to decimal, copy its value to
- a new register, pg*page-number-in-decimal, then restore %'s
- previous format. Compare the new register, not %, to 1 to
- determine whether special page one behavior should be used.
- (pg*end-page): Assign pg*next-format to %, not PN.

- This is a bit belt-and-suspenders for groff since our output

- support the 'c' conditional), it should prevent the strings from
- producing empty output.

- * tmac/an-old.tmac: Define an-end with .de1. We need to define

- because, as of 37b4180a27a6eeaea429e40ec278abefcda7f3a7 (11
- October), it can now be called from a trap executing in a
- context whence compatibility mode might be on (namely,

- * src/preproc/tbl/table.cpp (table::init_output): In the release
- macro written to the output, reword the warning diagnostic that
- is emitted when a table row is to be output without enough room
- before the next page location trap. The former wording said
- that a "text block" would not fit on the page, and that is
- normally how table rows grow longer than one line in the first
- place. However, there are other ways the conditional can be
- satisfied, as witnessed in Savannah #57665, so simply say what
- is known; that the table _row_ overruns the space to the next
- trap (we say the row won't "fit on [the] page").

- 1.10 (dc5351364982f78f8c630f1e856d692d4a82666f, 26 November
- 1995). Did you notice a two-font macro missing? It was: IR.
- Using it with the proscribed input fails to cause a problem; the

- unconditionally. Also define them with .de instead of .de1,
- since they will only be called within the contexts of macros
- that are already running with compatibility mode off (i.e., the
- public interface macros). Relocate definition of an-end to sit
- alongside these other continuous-rendering-mode specific macros
- and avoid a forward reference and scattering of \n[cR]
- conditionals around the file.
- (an-set-up-continuous-rendering): Define new macro to move
- macros (and end macro) into place. Call it at the end of the
- file only if cR eventually winds up being true.

- * tmac/an-old.tmac: Improve name space management. Rename .ne

-
- * tmac/an-old.tmac: Drop .ll hack for LL register.
-
- Drop the .ll hack for setting the line length on nroff devices.
-
- Once upon a time, the only way to get man pages to render on a
- terminal at any width other than the nroff default of 65n was to
- put an .ll request into the page--a mortal sin against
- portability--or your man(1) program could sneak such a request
- into nroff's input stream.
-
- Also, long ago, John Eaton of UT Austin wrote a man(1) program.
- In a few years this implementation branched into two lines of
- development, which I'll call man-db man (Wilford/Polacco/Watson)
- and another, Brouwer/Lucifredi man, which as of this writing saw
- its last release in 2011 (1.6g).
-
- The man and mdoc macros of groff 1.18 (July 2002) introduced an
- LL register to configure the line length, respecting an -rLL
- command-line option. The source change was made by Werner
- Lemberg on 3 May 2002 and Colin Watson updated man-db man(1)--on
- the same day!--to synthesize the option when calling groff.
-
- Later, in August 2005, Keith Marshall, a user of version 1.5m of
- Brouwer/Lucifredi man(1), which did not set the LL register,
- suggested that the existing .ll setting (technically, the value
- of \n[.l], the only way the result of an .ll request could be
- introspected) be honored in the absence of the LL register.
- However, it is impossible to distinguish a user-supplied ".ll
- 65n" request from nroff's default setting, which was in that
- case overridden to the modern default of 78n.
-
- And so, in what is now git commit
- f9d5df4aebd3d834b4084ffefa52a115e00dce38 (1 September 2005), it
- was done.
-
- This led to (1) surprising behavior for users accustomed to old
- methods and desirous of the nroff default and (2) lengthy
- apologia in groff source code comments and the groff_man(7) man
- page.
-
- Ironically, Brouwer/Lucifredi man(1) had already added support
- for the LL register by the time of its 1.6 release two months
- earlier (20 June 2005). (Curiously, it did so similarly to the
- old .ll hack, by injecting an '.nr LL' request into groff's
- input stream, rather than using the -r command-line option.)
- Moreover, Marshall and the groff list were already aware of
- this, but the change was accepted anyway because version 1.6
- was "too new"! (Distributions are slow sometimes, true...)
-
- Let us survey the field in 2020. man-db man(1) has supported
- the LL register for eighteen years, and Brouwer/Lucifredi man(1)
- for fifteen. Heirloom Doctools's man macros set the line length
- to 78n on nroff devices unconditionally. mandoc(1) similarly
- also always formats for 78 columns on terminals. groff's
- mdoc(7) macros grew support for LL in parallel with man(7) in
- 2002 and never added the \n[.l] introspection at all.
-
- There no longer seems to be any reason to preserve this hack.
-
- * tmac/an-old.tmac (initialization): Drop complex setup of LL
- register.
- (TH): Relocate line length reset; no behavior change.
- (after .mso man.local): Initialize LL only if the user hasn't;

-
- * makevarescape.sed: Use \[] form of special character escapes.
-
- The only man page we have that doesn't turn compatibility mode
- off (neqn) also doesn't use any sed-substituted patterns where
- characters replaced by a \[] special character escape form are
- likely to be used.
-
- The @g@ command prefix is the main avenue for intrusion of such
- escapes, but I think it improbable that many people are going to
- include apostrophes, double quotes, carets, grave accents, or
- tildes in the command prefix; some or all of these will pick
- fights with the shell and require quoting that we don't
- represent in man page text anyway.
-
- On top of that, neqn is largely a stub page.
-
- If it's a problem, a better fix than reverting this is to make
- neqn switch out of compatibility mode like our other man pages.

- mdoc: Relocate within build tree.
-
- The (modern) mdoc macro package has not been usable within the

- (after .mso man.local): Relocate setting of default hyphenation
- mode here (instead of just before .mso man.local). Eliminate
- conditional on \n[an-html]; this doesn't matter because
- grohtml(1) doesn't support hyphenation anyway. If it does learn
- to hyphenate, we should treat it the same as other output

- Adapt to the fact that \: reënables hyphenation. Rename
- "hyphenless [discretionary] break" to "non-printing break point"
- in documentation.
-
- * doc/groff.texi (Manipulating Hyphenation): Rename "hyphenless
- break" to "non-printing break point". Clarify that it is the
- soft hyphen glyph, not necessarily a hyphen, that is ordinarily
- written to the output on hyphenation breaks. Note that the
- remainder of a word after \: is subject to hyphenation as
- normal. Note (new) '\:\%' idiom for getting what people will
- want at least some of the time. Update example to use it.
- * makevarescape.sed: Insert \% after we insert \: to rewrite
- slashes in filenames, to protect later portions of the filename
- from hyphenation.
- * man/groff.7.man (Escape Sequences/Escape short reference):

-
- * tmac/groff_man.7.man: Rename...
- * tmac/groff_man.7.man.in: ...to this.
-
- * tmac/groff_man.7.man.in: Add m4 directives and define macros.
- Protect m4 keywords in English from unintended expansion (this

- style guide. Convert marker comments into m4 macros for content
- control. Uncomment material intended only for basic reference
- page.
-
- * tmac/tmac.am (man7_MANS): Add groff_man_style.7.
- (EXTRADIST) Add groff_man.7.man.in.
- (MOSTLYCLEANFILES): Add m4-generated man page sources
- tmac/groff_man{,_style}.7.man.
- Add targets to generate those same two pages from the renamed

- keywords and halt the build if they are found. Make generation
- of those pages depend on this new target.

-
- * tmac/groff_man.7.man: Add material on hooks and encoding.
- (Description, ./Deprecated features): Stop identifying .PT and
- .BT as "deprecated"; they shouldn't ever be called in man pages,
- but that has never been their intention.
- (Description): Identify character encoding and line-ending
- requirements (tutorial/style-guide material).
- (Description/Hooks): Add new subsection to house descriptions of
- .PT and .BT. Add mnemonic expansions for both.
-
-2020-07-31 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * man/groff.7.man (Control Characters): Incorrect claims were
- made. Double quotes can indeed be used to enclose arguments to
- string interpolations. The statement about a leading " in a
- string definition (or appendment with .as) was stated too
- generally. The leading quote is not necessary to include
- leading tab characters, which can be input as-is, even in
- compatibility mode.
-
-2020-07-28 G. Branden Robinson <g.branden.robinson@gmail.com>

- Migrate macro packages from font CW to CR. The font name "CW"
- {"constant-width"} is a legacy item we can dispose of (except
- for the DVI device, which also has CWI for "constant-width
- italic"), and much of the groff codebase already did starting
- with commit 0de1d6d79cdb959ffa7dac3af77c2a36ef31873f {October
- 2017}. Courier is available in the usual four styles {roman,
- bold, italic, bold+italic}.
-
- * tmac/an-ext.tmac (.EX): Set font to R, not CW. The existing
- .ft request was somewhat redundant with the '.do fam C'
- immediately before, which set the font family to Courier.
- * tmac/s.tmac (.UC): Use font CR, not CW.
-
-2020-07-23 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/tty.tmac: Stop suppressing nonexistent font warning.
- Prompted by a 2017 suggestion and patch from Bjarni Ingi
- Gislason. Documents and macro packages that want to change the
- font family should do so in awareness that this is meaningless
- on terminal (nroff) devices (and -Thtml as well).

-
-2020-07-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/groff_man.7.man (.EE, .YS): Fix error: refer to "initial

- Incidentally, this fact points out why putting ".hy 0" or ".nh"
- in your man page is futile.
-
-2020-06-28 G. Branden Robinson <g.branden.robinson@gmail.com>

-2020-06-12 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * doc/groff.texi (Groff Options): Remove editorial comment about
- '-a' option being "useless". It isn't. Update example for
- contemporary systems (like Debian) and to reflect the fact that
- the GNU troff(1) man page needs to be preprocessed with tbl(1).
- (Invoking grotty): Recast discussion of -c option, importing
- much language from grotty(1) page rewrite from a year ago. Add
- program index entries for col, more, and ul. Fix transposition
- error in ISO document number.
-
- * src/devices/grotty/grotty.1.man (Description/Legacy output

-
- Update documentation of .ss request.
-
- * doc/groff.texi (Manipulating Filling and Adjusting): Rewrite
- documentation of .ss request and \n[.ss] and \n[.sss] escapes.
- Note that negative values are not permitted in either argument
- to .ss. Use new terminology, "minimal inter-word spacing" and
- "additional inter-sentence spacing" for clarity. Clarify that
- additional inter-sentence spacing is only used when the output
- line is not full when the end of a sentence occurs. Add index
- nodes to help readers find discussion of details of spacing
- between words and sentences. Move discussion of differences
- from AT&T troff to section "Implementation Differences". Update
- example to more closely resemble a real-world case, use second
- argument to .ss request, and eliminate hackish use of .nop
- request.
-
- * man/groff_diff.7.man (New number registers): Recast in
- parallel with the foregoing.
-
- * man/groff.7.man (Read-only registers): Use new terminology and
- describe \n[.ss] and \n[.sss] in meaningful terms, not by
- reference to arguments to the .ss request (which wasn't even
- accurate, because these registers have default values).

- grep and verify Emacs coding tag detection.
-
- * src/preproc/preconv/preconv.1.man (Bugs): Delete; its sole
- concern was the absence of this feature.
- (Usage): Document detection algorithm in more detail. Note
- which detection methods don't work on unseekable input (pipes).
- Offer recommendations for those struggling with encoding
- detection.
- (Usage/Coding Tags): Stop manipulating line adjustment. Use
- hyphen-minus (\- escape) characters in coding tag names, since
- they are literals that one might copy and paste. Stop
- referencing XEmacs, whose development appears moribund.
- (See Also): Add cross-references to iconv(3) and locale(7) man
- pages.
-
- * src/preproc/preconv/tests/smoke-test.sh: Test each of the

- to messages documenting auxiliary modes of invoking the program.
- The output doesn't look right without one, and it feels
- dishonest to not document the relevant options (-v, --version)
- disjunctively. I'm trying to strike a balance between the
- ultra-terse BSD approach and the ultra-garrulous GNU one (see,

- character code from map file in diagnostic.
- (main): Report invalid skew character position in diagnostic.
- Explicitly report insufficient arguments in addition to usage
- message. Lift invariant computed expressions out of loops (more
- to shorten long lines than because I think the compiler won't
- figure it out). Give content to "impossible assertion".
- (tfm::load): Capitalize TFM initialism in diagnostics.
- (usage): Use full capitals for parameters as is conventional.
- Document disjunction of -v/--version flag from other
- invocations.
-
-2020-04-29 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/utils/addftinfo/addftinfo.cpp (usage): Add overloaded
- version that accepts a constant string argument, which emits the
- argument as a diagnostic and then calls usage().
- (main): Add diagnostics to usage message where the problem is
- clear. Add comment explaining why it sometimes isn't.
- (usage): Refactor main usage message (which prints the summary)
- to report the actual names of the accepted option arguments
- instead of just "-param", which is not literally accepted.
-
- Sort param_table alphabetically for use by the usage message.

- * **/*.{man,tmac}: Save compatibility mode robustly.
-
- Use new \n[.cp] register to save compatibility mode.

- compatibility modes.

-
- Implement new read-only .cp register.
-
- Within a .do request, \n[.cp] holds the saved value of
- compatibility mode.
-
- The register \n[.cp] is specialized and may require a statement
- of rationale. When writing macro packages or documents that use
- groff features and which may be mixed with other packages or
- documents that do not—common scenarios include serial processing
- of man pages or use of the .so or .mso requests—you may desire
- correct operation regardless of compatibility mode in the
- surrounding context. It may occur to you to save the existing
- value of \n(.C into a register, say, _C, at the beginning of
- your file, turn compatibility mode off with “.cp 0”, then
- restore it from that register at the end with “.cp \n(_C”. At
- the same time, a modular design of a document or macro package
- may lead you to multiple layers of inclusion. You cannot use
- the same register name everywhere or you risk “clobbering” the
- value from a preceding or enclosing context. The two‐character
- register namespace of AT&T troff is confining and mnemonically
- challenging; you may wish to use groff's more capacious
- namespace. However, attempting “.nr _my_saved_C \n(.C” will not
- work in compatibility mode; the register name is too long.
- “This is exactly what .do is for,” you think, “.do nr
- _my_saved_C \n(.C”. The foregoing will always save zero to your
- register, because .do turns compatibility mode off while it
- interprets its argument list. What you need is:
- .do nr _my_saved_C \n[.cp]
- .cp 0
- at the beginning of your file, followed by
- .cp \n[_my_saved_C]
- at the end. As in the C language, we all have to share one big
- namespace, so choose a register name that is unlikely to collide
- with other uses.

- It's too easy for the nroff version to get desynced from the
- groff version when we're running test cases, leading to spurious
- results. Make it easier to see a discrepancy.
-
- * src/roff/nroff/nroff.sh: Call groff with -v or --version when
- we are called that way. Let test cases tell us to use
- test-groff as groff with an environment variable.
-
- * src/roff/nroff/tests/verbose_option_works.sh.in: Rename to...
- * src/roff/nroff/tests/verbose_option_works.sh: ...this. Check
- the nroff version being tested against the groff version being
- wrapped. This exposes a bug; the system groff rather than the
- build tree groff was being invoked. Refactor. Stop messing
- with @GROFF_BIN_PATH_SETUP@ (enabling the rename); instead, let
- test-groff handle that for us. Locate it and export the
- variable GROFF_TEST_GROFF so nroff can find it. Because we
- manipulate $PATH to run the tests, the $PATH of an installed
- groff system will _always_ differ from that used by a build
- tree; ignore it in the test cases. Dispose of bashisms and set
- shebang to /bin/sh.
-
- * src/roff/nroff/nroff.am: Stop generating the above test
- script. It can now be run as it ships.

-
- Make our assert() C99-conformant.
-
- groff has its own implementation of the standard C library's
- assert() macro. It hasn't been updated since C89. C99 requires
- that the diagnostic emitted by assert() contain the failing
- expression and name of the function in scope.
-
- * src/include/assert.h: Add additional pointer to const char
- arguments to do_assert() and assertion_failed() for function
- name and stringified expression.
- (assertion_failed): Update prototype.
- (do_assert): Accept 'func' and 'msg' parameters and pass them to
- assertion_failed().
- (assert): Update macro to collect '__func__' and stringify the
- expr parameter (as 'msg') and pass them do do_assert().
- * src/libs/libgroff/assert.cpp (assertion_failed): Rewrite
- diagnostic to more closely match GNU Coding Style format and
- also report function and failing expression.
-
- Example output:
- troff: ../src/roff/troff/input.cpp:2644: do_request():
- assertion failed: '0 == "But first, here's a rotten old
- BBC programme."'
-
- We have no excuse to assert(0) ever again. Express the
- invariant that has been violated.

-
- Enable backtracing across process/file boundaries when errors or
- non-ignored warnings are encountered.
-
- Experimentation reveals that .so, .mso, and .pso requests acted
- as barriers to backtracing except when explicitly requested with
- the .backtrace request. Judging by the git history, this
- behavior dates back to June 1991 or earlier. The intention,
- according to a source comment, was only to suppress the
- backtrace output for the line corresponding to the outermost
- level of the input stack (commonly, a file argument to groff).
- Unfortunately, that wasn't its only effect.
-
- This change does result in one additional line of output for
- each error or (non-ignored) warning when -b is given. However,
- I regard this as unobjectionable because {1} a backtrace was in
- fact explicitly requested; and {2} it seems a poor tradeoff to
- suppress most of the backtrace in some complicated and
- frustrating cases for the sake of one fewer line of backtrace
- output in a trivial one.
-
- Now, backtracing behaves the same no matter what triggers it.
-
- Fixes Savannah #58153.
-
- * src/roff/troff/input.cpp (file_iterator::backtrace): Call
- get_location() for its side effect of rewriting a filename of
- "-" to "<standard input>", for consistency with other diagnostic
- messages. (In this class, this member function always returns
- 1, so ignore the return value. This fact is an essential part
- of what led to the bug; the conditional
- p && !p->get_location(0, &f, &n)
- which appeared in the for loop of input_stack::backtrace() prior
- to this change would always evaluate to false when a node of the
- file_iterator class was encountered.)
- (input_stack::backtrace): Replace member function body with that
- of input_stack::backtrace_all().
- (input_stack::backtrace_all): Delete.
- (backtrace_request): Update the only call site of the above.
-
- * src/roff/groff/tests/regression_savannah_58153.sh: Add test.
- * src/roff/groff/groff.am (groff_TESTS): Run test.
-
- * src/roff/groff/tests/string_case_xform_errors.sh: Update
- regression test to not be confounded by additional line of

-2020-04-10 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Reorganize backtrace output.
-
- * src/roff/troff/input.cpp (string_iterator::backtrace):
- Prefix the output with the program name if it is known. In a
- deviation from the GNU Coding Standards, put the string
- "backtrace:" immediately next instead of the file and line
- number; this is because, particularly in cases where the
- backtrace is most interesting or needed, it will produce
- multiple lines of output and the common prefix aids visual
- understanding.
- (file_iterator::backtrace): As above; also, change prefix for
- popened nodes in the iterator from "process" to "pipe". This
- seemed preferable to omitting the information entirely or using
- an inscrutable sigil like 'f' or 'p'. The advantage is that the
- output is better aligned--better ergonomics for those who have
- to cope with a lot of it. Furthermore, output the filename only
- once.
-
- Example of old and new output:
-
- /tmp/inner:2: backtrace: file '/tmp/inner'
- echo .so /tmp/inner:1: backtrace: process 'echo .so /tmp/inner'
- /tmp/outer:1: backtrace: file '/tmp/outer'
-
- troff: backtrace: file '/tmp/inner':2
- troff: backtrace: pipe 'echo .so /tmp/inner':1
- troff: backtrace: file '/tmp/outer':1
-

-
- * src/roff/troff/input.cpp (read_size): Add units to diagnostic.
- This function works only with device-specific basic units
- internally; users likely think in terms of point size, so add
- the basic unit suffix "u" to offer a hint about what's going on.
-
- Example:
- $ groff -ww >/dev/null
- \s[10]A\s[-12]B
- troff: <standard input>:1: warning: point-size escape results in
- non-positive size -2000u; set to 1u
-
- On a PostScript device with 1000 basic units to the point, the
- difference is important and would be confusing without the unit
- indication.
-
-2020-04-08 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Correct and clarify point size documentation.
-
- Our Texinfo manual has long documented the request '.ps 0' as
- restoring the previous point size (just as '\s0' or '.ps' with
- no argument does), but this is incorrect; since groff 1.02 or
- earlier (June 1991), the request has not actually worked this
- way. Instead, '.ps 0' sets the point size to 1 basic unit
- {though output drivers may clamp this to a higher value}. This
- behavior is consistent with AT&T troff, Hierloom Doctools troff
- and, per Ingo Schwarze, Plan 9 troff. (It is, however, not
- consistent with neatroff.)
-
- * doc/groff.texi (Changing Type Sizes): Stop claiming that '.ps
- 0' works like '\s0'. Note that the resulting (computed) point
- size, not the argument, is clamped. Note that it is
- non-positive, not negative, point sizes that are clamped to 1u.
- Add (forward) cross-reference to section where \n[.ps] is
- defined since it is mentioned here. Move explanation of special
- handling of zero argument to \s escape description.
-
- * man/groff.7.man (Request short reference): Explain .ps N
- independently of \s. Note clamping behavior.
-
-2020-04-06 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (read_size): Correctly brace 'else'
- block.
-
- * src/roff/groff/tests/\
- use_point_size_escape_with_single_digit_arg.sh:
- Check that we get a diagnostic when relying on ambiguous form.
-
-2020-04-04 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/roff/troff/input.cpp (read_size): Move special-case
- interpretation of the '\sN' form of point-size escapes when 'N'
- is 1, 2, or 3 to compatibility mode (groff -C) only, and throw
- error diagnostic with suggestion for remedy if encountered.
-
- Traditionally, '\s36A' is interpreted as "set point size to 36,
- then emit 'A'". However, only values in the range 10-39 are
- handled specially; '\s40A' is interpreted as a four-point "0A".
- This is unlike anything else in *roff grammar; see \*, \$, \f,
- \F, \g, \k, \m, \M, \n, \V, \Y, and \z.
-
- To anticipate objections: Why not throw only a warning? Because
- there isn't a warning category for supported but ambiguous
- syntax (this behavior of AT&T troff dates back to the mid-1970s
- but was not documented in the Troff User's Manual until 1992).
- Why not throw the error outside of compatibility mode too?
- Because outside of compatibility mode we (now) have an
- unambiguous parse.
-
- Background: The Graphic Systems C/A/T phototypesetter (the
- original device target for AT&T troff) only supported a few
- discrete point sizes in the range 6..36, so Ossanna
- special-cased the parser to do what the user must have meant.
- Kernighan warned of this in the 1992 revision of CSTR #54
- {§2.3}, and more recently, McIlroy referred to it as a "living
- fossil".

-
- * tmac/s.tmac: Remove code block that attempted to enable all

- could specify -w options that exactly matched the default and
- the test would not be able to tell, causing puzzling and
- undesired behavior. Furthermore, the hard-coded default was out

-
- Accept any number of arguments for .Dd in the groff_mdoc(7)
- macros.
-
- * tmac/doc-common-u: The .Dd macro behaved in a weird way:
- Without arguments, it printed the string "Epoch".
- With one, two, four, or more arguments, it ignored all arguments
- and used the current date instead.
- Only for exactly three arguments, it printed the arguments.
- None of this made sense. Giving the date as "Epoch" is
- absurd, and printing the current date is just misleading:
- why should a document be considered up-to-date when the author
- did not even bother to state the date of the last change?
- Admittedly, the behaviour for 0 and 4 or more arguments
- already appeared 4.3BSD-Reno, and the behaviour for 2 or 3
- arguments in 4.4BSD. But it was already wrong even in those
- days: several manual pages in 4.4BSD gave .Dd a single, quoted
- argument, e.g. .Dd "June 9, 1993": cap_mkdb(1), id(1), sed(1),
- err(3), getcap(3), sysctl(3), amd(8), disklabel(8), and others.
- Consequently, simply print all the arguments, no matter how
- many there are.

- This bug was found by Jonathan Gray <jsg@openbsd.org>
- while he looked at 4.xBSD manual pages.

-
- Repair .AT and .UC in the groff_man(7) macros.
-
- * tmac/an-old.tmac: Setting user-defined strings in a macro that
- will later be called indirectly from page location traps is
- excessively complicated. Besides, the implementation doesn't
- work: when the trap is finally sprung, the defaults from the
- an-init macro clobber what the author specified with .AT or .UC.
- Instead, all that is needed is setting the strings for the
- header before triggering the page break, such that they appear
- right away, while setting the strings for the footer after the
- page break, such that they don't appear on the previous page.
-
- This bug was found by Jonathan Gray <jsg@openbsd.org> while he
- looked at 4.xBSD manual pages.

-
- * tmac/tests/an-old_CS_register_on.sh: Tweak flags; all the
- other tests in this group pass "-Tascii -P-cbou" instead of
- "-Tutf8". (This is so that output is easy to grep from a shell
- script.) Bring this test into line. Does not regress anything.

-
- Certain pdfmark destination names caused gropdf to fail.

-
-2019-09-22 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Use a vertical spacing of 1v between paragraphs in man page
- examples. This looks better (on typesetter devices like
- PostScript and PDF) with the Courier font family also used in
- examples. Typewriter devices (like the terminal) already used
- an inter-paragraph spacing of 1v.
-
- * tmac/an-ext.tmac (EX): Save the value of the PD number

-
- * tmac/an-old.tmac: Move test for definitions of CS and CT

-
- Retire '@G@' build system macro.

- It existed only for forcibly-capitalized man page titles; it was
- the uppercase-transformed counterpart of @g@.
-
- * Makefile.am: Delete sed transformation of @G@.
- * src/preproc/tbl/tbl.1.man: Replace '@G@EQN' in section heading
- with '@g@eqn'.
-
-2019-09-10 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * **/*.man: Downcase man page titles, except for glilypond and
- roff2*, which did not require it.
-
- Here's a sed script for the aid of those who have a corpus of
- man pages to migrate.
-
- # Downcase man page titles.
- #
- # Use the first line to skip any .TH lines that require
- # special handling, perhaps because the name of the
- # command gets externally macro-expanded. In groff, the
- # "roff2.1.man" page is an example.
- #
- # This script operates _only_ on .TH lines.
- #
- # usage: sed -i -f this_script.sed your_man_page.1 ...

-
- The an (man) macro package supports new CS and CT number
- registers to control rendering of man page section headings and
- titles, respectively, in full capitals. These default off (with
- no visible effect on pages which already fully capitalize these
- strings in man page sources). The rationale is to encourage man
- page authors to preserve case distinction information in (or
- restore it to) their titles and section headings, while giving
- users (including system administrators, distributors,
- integrators, and maintainers of man(1) implementations) a way to
- view the rendered page elements in full capitals if desired.
-
- * tmac/an-old.tmac (TH/an-init): If number register CT is
- defined and nonzero, call .stringup on \*[an-title].
- (SH): Store macro argument list to \*[an-section-heading]. If
- number register CS is defined and nonzero, call .stringup on it.
- * tmac/groff_man.7.man (OPTIONS): Document the CS and CT number
- registers.
- * tmac/tests/an-old_CS_register_off.sh:
- * tmac/tests/an-old_CS_register_on.sh:
- * tmac/tests/an-old_CS_register_unspecified.sh:
- * tmac/tests/an-old_CT_register_off.sh:
- * tmac/tests/an-old_CT_register_on.sh:
- * tmac/tests/an-old_CT_register_unspecified.sh: Add tests.
- * tmac/tmac.am (tmac_TESTS): Run tests.
-
-2019-09-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Add regression test to check behavior of case transformation
- request on a string containing a Unicode character escape.
- Right now, this is not supported, so it is an XFAIL test in the
- parlance of DejaGNU/POSIX 1003.3.
-
- * src/roff/groff/tests/string_case_xform_unicode_escape.sh: New
- test.
- * src/roff/groff/groff.am (groff_TESTS): Run test.
-
-2019-09-09 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- Implement .stringdown and .stringup requests.
-
- * src/roff/troff/input.cpp: Add .stringdown and .stringup

- * doc/groff.texi: Document them, including example.
- * man/groff_diff.7.man: Same.
- * man/groff.7.man: Document them briefly.
-
-2019-09-09 G. Branden Robinson <g.branden.robinson@gmail.com>

- * src/roff/groff/groff.am (groff_TESTS): Run tests.
-
-2019-06-30 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/devices/grotty/grotty.1.man (Options/-i): Note support of
- recent versions of xterm for italic (oblique) styles.
-
- Fixes part of <https://savannah.gnu.org/bugs/?55278>.
-
-2019-06-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- devlatin1: Map \(oq to ' on output.
-
- * font/devlatin1/R.proto: Render the output glyph \[oq]
- {opening quote} as 0x27 (apostrophe) instead of 0x60 (grave
- accent). A grave accent is just flat wrong for the Latin-1
- character set, a.k.a. ISO 8859-1. The defining document ECMA-94
- {June 1986} is freely available for perusal. The ECMA-94 Latin
- character sets do not define any glyphs for directional
- {"typographer's"} quotation marks, but the apostrophe is
- depicted as a neutral (vertical) glyph, whereas the grave accent
- 0x60 and acute accent 0xB4 are mirror-symmetric diacritical
- marks.
-
- Note that this change has no effect on _input_ conventions for
- roff source documents. You can still get directional single
- quotes on UTF-8, PostScript, PDF, and other output devices
- supporting them by typing sequences like `this' in the input
- {character remapping with ".char" requests and similar
- notwithstanding}.
-
- Patch and idea from Ingo Schwarze, who originally proposed it
- for ASCII as well, and included Latin-1 for parallelism.
- The groff developers could reach no consensus about the wisdom
- of such a change for ASCII (which was designed to support
- ambiguity for some code points, requiring the development of
- supplementary interpretation conventions between parties).
- ECMA-94/ISO-8859 is more strongly prescriptive.
-
- See https://savannah.gnu.org/bugs/?55616 and the groff mailing
- list archives for 31 January to 23 February 2019 at
- https://lists.gnu.org/archive/html/groff for lengthy discussion.
-
- * src/roff/groff/tests/on-latin1-device-oq-is-0x27.sh: Check for
- correct output glyph.
-
- * src/roff/groff/groff.am: Add test.
-
-2019-06-28 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * tmac/unicode.tmac: Save and restore compatibility mode since
- the script uses a GNU extension (.char).
-
-2019-06-27 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- libdriver: Fix SEGV (Savannah #56555).
-
- * src/libs/libdriver/printer.cpp: Check result of
- set_char_and_width() for error condition before relying on it.
-
- * src/roff/groff/tests/regression-56555.sh: Provoke segfault
- with five bytes of input using transparent line indicator.
-
- * src/roff/groff/groff.am: Add test.
-
- Fixes <https://savannah.gnu.org/bugs/?55278>.
-
-2019-01-12 Ingo Schwarze <schwarze@openbsd.org>
-
- Correctly handle groff_mdoc(7) .Lk arguments starting with a
- dot.
-
- * tmac/doc.tmac-u: Each argument to the .Lk macro is printed
- on its own roff input line. If it happens to start with a dot
- or apostroph, it was misinterpreted as a request or macro.
- Force it to be treated as text by adding "\&" in front of it.
-
-2018-12-31 Ingo Schwarze <schwarze@openbsd.org>
-
- * man/groff_diff.7.man: remove two stray .RE macros

-
- [tbl]: Refactor handling of type size and vertical spacing.
-
- * src/preproc/tbl/table.h (struct inc_number): Rename this...
- (struct size_expression): ...to this, and change its member
- types. The `inc` `short` becomes a `relativity` enum
- because it only ever takes 3 values. The `val` short becomes an
- `int`, undoing what I suspect to be premature optimization.
- * src/preproc/tbl/main.cpp (entry_modifier::entry_modifier)
- (entry_format::debug_print, process_format):
- * src/preproc/tbl/table.cpp (set_modifier, set_inline_modifier)

-
- * src/preproc/tbl/main.cpp (process_format): Check for EOF after
- eating spaces and tabs when processing [pPvVwW] column
- modifiers, and emit an appropriate error diagnostic. This was
- already being done for [fFmM].
-
-2023-05-19 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * src/preproc/tbl/main.cpp (process_format): Accept (and
- discard) space and tab characters after [pPvV] in a column
- descriptor, as is already done for [fFmMwW]. Modify [wW] to use
- the same loop style as the others, for consistency.

-
- [eqn]: Implement tunable "half_space" and "full_space"
- parameters. They default to the same widths as "thin_space" and
- "thick_space", respectively, but control the widths of the '^'
- and '~' input tokens.
-
- * src/preproc/eqn/box.cpp: Add globals `half_space`,
- `full_space`.
- (struct S): Recognize "half_space" and "full_space" as
- parameters to the "set" primitive, and map them to the globals.
- (half_space_box::output): Format the half space width.
- (full_space_box::output): Format the full space width.
- (full_space_box::output, thick_space_box::output): Drop

-
- [troff]: Fix Savannah #64166.
-
- * src/roff/troff/node.cpp (bold_font): Add `WARN_MISSING`
- diagnostic if request given no arguments; it does nothing, and
- the behavior of this request is sufficiently complex that it's
- worth saying so. Stop throwing font lookup error if second
- argument cannot be resolved as a font name; it might be an
- emboldening amount instead.

- operator.
-
-2023-05-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Fix Savannah #64104.

- control characters.
- * doc/groff.texi (Using Escape Sequences): Document
- restrictions.
-
- * src/roff/troff/env.h (class environment): Slightly refactor.
- Rename fields `control_char` and `no_break_control_char` to
- `control_character` and `no_break_control_character`,
- respectively, and make them private. Add public getters and

- `unsigned char` and returns a `bool`.
- (get_no_break_control_character):

- * src/roff/troff/env.cpp (environment::environment): Update
- constructors to use new field names and initialize them in their
- new order of declaration.
- (environment::copy): Similar. (Not to be confused with a copy
- constructor, this member function implements the operation of a
- valid `evc` GNU troff request.)

- (environment::set_control_character):
- (environment::get_no_break_control_character):
- (environment::set_no_break_control_character): Implement.

- requests.
- (control_char, no_break_control_char): Drop implementations.
- (init_env_requests): Drop `init_request` calls for them.
-
- * src/roff/troff/input.cpp: Resurrect handling of `cc` and `c2`
- requests here, with more error handling.
- (assign_escape_character, process_input_stack): Use the new
- getters defined above in environment object since the relevant
- fields are now private.
- (assign_control_character): New function assumes the former
- responsibilities of env.cpp:control_char and rejects the request
- if the desired character is already the escape or no-break
- control character.
- (assign_no_break_control_character): New function assumes the
- former responsibilities of env.cpp:no_break_control_char and
- rejects the request if the desired character is already the
- escape or control character.
- (process_input_stack): Reorder comparisons to avoid inadvertent
- lvalue assignment. Add parentheses to assignment with complex
- RHS.
- (init_input_requests): Attach `cc` and `c2` requests to new
- functions above.
- * doc/groff.texi (Control Characters): Document restrictions.
-
-2023-05-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [troff]: Don't quote a character with itself in diagnostics.

-
- [troff]: Revise output warning diagnostic format.
-
- * src/roff/troff/input.cpp (do_error): For the `OUTPUT_WARNING`
- value of the `error_type` enum, spell out the words "page" and
- "diversion" instead of abbreviating them, and place the
- diversion information (if present) in parentheses.

-
- [troff]: Drop `POPEN_MISSING` preprocessor macro.
-
- 3 source files test this macro but nothing appears to define it.
- It dates back to (at least) 1994. I suspect this of being
- bitrot. Reasons include: (1) We test for a declaration of
- `popen` in our "configure.ac" file; (2) our gxditview command
- uses `popen` _without_ #ifdef-guarding it (perhaps the
- assumption was that any system that supported X11 also had a
- working `popen`); (3) our "nonposix.h" header file defines a
- macro aliasing `popen` to `_popen`, which is its typical name on
- Windows systems, and is the most likely build host candidate for
- which support might have been missing as late as 1994.
- Microsoft end-of-lifed MS-DOS in 2000. If someone wants to
- start up a FreeDOS port, talk to us. Maybe even that has a
- functional `popen()`. Here's hopin'.

- [troff]: Make futile aliasing an error.
-
- * src/roff/troff/input.cpp (alias_macro): Promote diagnostic
- when attempting to alias a nonexistent macro/string/diversion
- from warning to error; this aligns with the handling of the
- requests `chop`, `stringup`, `stringdown`, `substring`,
- `asciify`, `unformat`, and `writem` when they are regarded as
- impossible. Further, attempting to alias a nonexistent object
- does not create an empty one, unlike interpolating it; try ".als
- baz qux", then ".pm".
- * src/roff/troff/reg.cpp (alias_reg): Promote diagnostic when

- [man]: Preserve user-selected font family.
-
- * tmac/an.tmac: When initializing, save the currently selected
- font family as `an*body-family` instead of forcing 'T' (Times,
- which is the formatter's default, even on nroff-mode devices
- that can't switch families). This change makes the formatter's
- `-f` option work on man(7) documents again (important for
- Japanese man pages, but there is now once again nothing stopping
- you from viewing man pages in Palatino or Helvetica on the 'ps'
- and 'pdf' devices where these families are available). It also
- reopens an avenue for rogue pages to affect the rendering of
- unrelated documents later in batch rendering, but there are many
- other, and worse, ways for rogue pages to do damage. Problem
- introduced by me in commit e0e16d8e65, 15 March 2022.

- [man]: Stop `HP` producing excess vertical space.
-
- * tmac/an.tmac (HP): Fix thinko/typo when expanding macro as
- string to call `an-deprecation-warn`.
- * tmac/an-ext.tmac (SY): Put 1v of vertical space on the output
- if we are starting a (non-nested) synopsis.
-
- Thanks to Alex Colomar for the report. Problem introduced by me
- in commit aea1dfb11b, 6 March 2022.

-
- [pdfpic]: Refactor.
-
- * tmac/pdfpic.tmac: Migrate gathering of image dimensions from
- `sy` and a temporary file to `pso`.
- (pdfpic@cleanup): Drop `pdfpic*temporary-file` string.
- (pdfpic@get-image-dimensions): Remove redirection. Invoke
- `pso`, not `sy`.
- (PDFPIC): Stop constructing `pdfpic*temporary-file` string.
- Stop testing `systat` register. Stop sourcing and deleting
- temporary file.
-

-
- * tmac/pdfpic.tmac: Refactor to make comprehensible some
- woefully undocumented cleverness and improve efficiency.
- (PDFPIC): Break out flaming-hoop-leaping "clever" bit of `sy`
- usage into its own macro, calling from here and relocating its
- requests from here...
- (pdfpic@get-image-dimensions): ...to here. When using `sy`
- request to collect and munge output of pdfinfo(1), (a) disable
- the escape character while defining the macro; (b) construct the
- command in a roff string, appending to it in discrete, hopefully
- comprehensible chunks; (c) disable the escape character during
- macro interpretation wherever possible (most of it); (d) retain
- doubled backslashes so that they survive subsequent string
- interpolation; (e) stop using grep(1) in the pipeline when
- sed(1) is perfectly capable of performing its own input
- filtering; (f) invoke sed with '-n' option and emit output only
- upon a successful substitution; (g) replace unportable(!) POSIX
- BRE character class '[:digit:]' in substitution match text with
- '[0-9]'; and most importantly (h) replace multi-line sed 's'
- replacement text (see below for the reason we can't use it) with
- single roff control line employing the groff extension escape
- sequence `\R` to assign multiple registers. Annotate
- portability and escaping challenges. Tested on GNU/Linux, macOS
- 12, and (with simulated pdfinfo(1) output) Solaris 11.
-
- There is a problem with trying to embed true newlines into the
- arguments of a `sy` request. The C++ function that GNU troff
- uses to assemble the command string (character by character)
- _does not recognize C/C++ string literal escape sequences_.
- This means that you _cannot_ embed "\n" in `sy`'s arguments and
- have it survive, as a newline character, into the command string
- passed to the standard C library's system(3) function. ("A\nB"
- gets encoded as 'A', '\\', 'n', 'B', not 'A', '\n', 'B'.)
- Unfortunately, this appears to be AT&T troff-compatible
- behavior. But it means that you _cannot_ portably construct
- multi-line replacement text for sed's 's' command. (Other sed
- commands like 'a', 'c', and 'i' will be similarly affected.)
- See Savannah #64071.

-
- * tmac/es.tmac: Spell weekday and month names in lowercase;
- every style authority I could find online mandates this, and it
- meshes with my half-remembered formal instruction in the
- language. Fix groff composite special character escape
- sequences to place the base character first. Replace one
- Unicode special character escape sequence with a composite

-
- * tmac/koi8-ru.tmac: Rename this file...
- * tmac/koi8-r.tmac: ...to this. There _is_ a "KOI8-RU"
- encoding, which appears to subsume KOI8-B and KOI8-U (by
- replacing more box drawing characters), but this file does not
- remap their values to applicable Unicode code points.

-
- * tmac/s.tmac (@EQ): Trivially refactor. Shift valid
- pseudo-enumeration type values from 0..2 to 1..3 so that they
- more idiomatically test for truth values in roff (where zero and
- negative values are false). Simplify a conditional accordingly.
-
-2023-04-07 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [ms]: Fix Savannah #64013.
-
- * tmac/s.tmac (@EQ): Revise argument handling. If there is only
- one argument and it is not a recognized alignment, warn and
- treat it as an equation label. If there are two arguments but
- the first is not a recognized alignment, throw a warning
- diagnostic (but still use default alignment with the second
- argument as label). An explicitly empty first argument is
- synonymous with "C".

-
- * tmac/s.tmac (@break-page, bp): Define alias for `bp` request
- and wrapper for `bp` to (if needed) temporarily disable no-space

- package wrapper ("-man") on hosts with a system man package with
- a request to source itself; this was search-and-replace damage
- from resolving Savannah #60789. The wrapper still worked, but

- in the "pdf/" subdirectory of the destination "doc" directory.
-
- * doc/doc.am (PROCESSEDDOCFILES): Drop
- "$(PROCESSEDDOCFILES_PDF)" from macro definition.
- (nodist_docpdfdoc_DATA) [USE_GROPDF]: Use it here instead,
- replacing a literal "doc/automake.pdf".
- (mostlyclean-doc) [USE_GROPDF]: Clean these same files.

- * m4/groff.m4 (GROFF_CHECK_GROHTML_PROGRAMS)
- (GROFF_GROHTML_PROGRAM_NOTICE, GROFF_PNMTOOLS_CAN_BE_QUIET):
- Rename "make_htmldoc" to "use_grohtml" as expected by
- "configure.ac". Also stop `AC_SUBST`ing it; we don't need
- "@use_grohtml@" in our Makefiles since an `AM_CONDITIONAL` in
- configure.ac already does an equivalent thing. Continues commit

-2023-03-13 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- [build]: Clarify output of `GROFF_TMAC` Autoconf test.
-
- * configure.ac: Correct characterization of the list of macro
- packages reported. It is not the list of macro packages
- receiving a "g" prefix, but the list of macro packages reciving
- a wrapper macro file in groff's macro directory, each of which
- sources the corresponding system (likely AT&T-descended troff)
- macro package. Fixes wording I introduced in commit 4d30dd7424,
- 31 May.
- * m4/groff.m4 (GROFF_TMAC): Clarify first "checking" message:
- we are looking for a file name prefix on existing system macro
- packages (like "tmac."). This has nothing to do with the prefix
- applied to groff commands, or the "g" prefixed to groff
- implementations of the man, mm, and ms packages. Tighten
- wording of second "checking" message. Consistently say "(none)"
- instead of "none" or "none found".

-
- * doc/doc.am (install-txt): Look for "groff.txt" in the source
- and build directories in sequence; it could be in either place
- depending on whether the build is from the Git repository or
- from a distribution archive. Annotate this. Fixes
- "install-doc" target when building from Git repository. Problem
- introduced by me in commit 691fc70108, 22 February. Thanks to
- Nikita Ivanov for the report.
- (install-pdf-local, install-html-local): Similar.

-2023-04-20 Bruno Haible <bruno@clisp.org>
-
- [build]: Fix gxditview linking on AIX.
-
- * m4/groff.m4 (GROFF_X11): Add macro dependency on
- `AC_CANONICAL_HOST`. Introduce new variable `X_AW_DEPS`, empty
- on most hosts. If we otherwise have Athena widget library
- support, and the host is AIX, force linkage against Xpm and Xext
- libraries to reflect modern Athena dependencies, which AIX's
- linker doesn't figure out on its own. `AC_SUBST` this variable,
- exposing it to Automake files.
- * src/devices/xditview/xditview.am (gxditview_LDADD): Use it.
-
- {A similar change might also be useful for HP-UX, another Unix
- System V descendant; see
- <http://hpux.connect.org.uk/hppd/cgi-bin/wwwtar?/hpux/Gnu/\

-
-2023-04-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * bootstrap.conf (gnulib_modules): Add "sys_wait" module. MinGW
- does not provide "sys/wait.h", which we require in
- src/preproc/html/pre-html.cpp since commit 11137209ed, 27 June.
-
-2023-04-20 G. Branden Robinson <g.branden.robinson@gmail.com>
-
- * Makefile.am: Initialize (as empty) Automake variables that we
- don't use but which gnulib modules expect to be defined.
- (AUTOMAKE_OPTIONS, SUBDIRS, noinst_HEADERS, noinst_LTLIBRARIES)
- (pkgdata_DATA, MOSTLYCLEANDIRS, AM_CFLAGS): Do it.
-
- Thanks to Bruno Haible for the advice.

-2023-04-22 G. Branden Robinson <g.branden.robinson@gmail.com>
