Does it make sense to export these knobs as named paramteres to
@Break? Different countries seems to have slightly different
typographic traditions, including variations of what is considered
good/acceptable spacing.
E.g. some constraints for russian (from an editors' reference book) are:
- optimal spacing is 0.5f
- spaces in one line should be equal
- spacing in adjacent lines, if different, should be close to each
other (function space(lineno) should be "smooth")
- space between words in different font sizes should be equal to
spacing for the bigger font
- maximum stretch depends on a type of publication (book dictionary),
page size and font size. E.g. for books and font size under 12p the
maximum spacing is 0.75f.
minimum spacing is 0.25f
- varying intra-word (inter-letter) spacing to achieve acceptable
inter-word spacing is preferrable to breaking inter-word spacing
contraints. Stretch +1p, shrink -0.5p.
- all outdented paragraphs should have the same (+-1p) outdent amount
reagardless of their font size
- last line of paragraph should be 1) at least 1.5 longer than
paragrpaph indent, xor 2) at least 2f if there's no paragraph
indent, or paragraph is outdented.
- final space in the last line of adjusted or outdented paragraph
(Lout's automagic &1rt) should be at least 1.5f or the final line is
adjusted to be full line.
- final space of paragraph w/out paragraph indent should be at least 24p.
SY, Uwe
