;;; Commentary:
;; This file collects my code for working with LaTeX under Emacs. I
;; use these commands together with LaTeX mode. I tend to have no
;; trouble typing math "in real time", as I take lecture notes for
;; example.
;; Since this file makes available a large number of functions that
;; one needs to be able to select and execute very quickly, the choice
;; of bindings is important (see austex-bindings.el).
;; In order to use these commands and bindings with LaTeX mode, place
;;
;; (add-hook 'latex-mode-hook 'austex-mode)
;;
;; in your .emacs configuration file.
;; Some people might wonder why I don't just use AUCTeX. Other than
;; the simple answer that I think my bindings are better, there are
;; two additional reasons. When I was learning to type math with
;; Emacs, the AUCTeX learning curve seemed too steep. Also, AUCTeX's
;; advertised functionality seemed like overkill for what I wanted to
;; do. Eventually, if I continue to develop this code, I will
;; probably cherrypick things I like from AUCTeX's code. The name of
;; this file is a joke on AUCTeX and AUStin TEXas.
;; Some people are sure to frown on the duplication of effort and the
;; fact that my code is not as nice in many ways. Perhaps others will
;; appreciate the speed and simplicity of the approach I've been
;; using. The speediness probably comes down to choice of bindings.
;; The simplicity in part a side-effect of the fact that I haven't
;; made any effort to provide an additional customization layer: if
;; you want to change the way this package works, change the code. No
;; effort has been made to be fully general, so you may well have to
;; do some editing to get this file to do what you want.
;; Thanks to Klaus Berndl for help with the macro evaluation strategy.
;; An alternative approach was suggested by Daniel Pittman, viz.,
;;
;; (dolist (name '("alpha" "beta"))
;; (fset (intern (concat "austex-" name))
;; `(lambda () (interactive) (insert "\\" ,name))))
;;
;; And this is tighter...
;;; History:
;; I decided to revise my LaTeX-under-Emacs code into this
;; "publishable" form following email conversations with Ross Moore
;; about what makes a good LaTeX macro. Many "convenience" LaTeX
;; macros should actually be handled at the editor-macro level. My
;; hope is that this code will be a positive contribution to the
;; development of a tightly integrated and correctly divied up editing
;; environment for mathematical writing.
;;; Future:
;; First of all, add navigation features. Cf. cdlatex.el where
;; `cdlatex-tab' is defined; its docstring says
;;
;; The cursor stops...
;; - before closing brackets if preceding-char is any of -({[]})
;; - after closing brackets, but not if following-char is any
;; of ({[_^
;; - just after $, if the cursor was before that $.
;; - at end of non-empty lines
;; - at the beginning of empty lines
;; - before a SPACE at beginning of line
;; - after first of several SPACE).
;;
;; It would be good to do this sort of thing, but (probably) in more
;; generality. (I should test out `cdlatex-tab' to see how it
;; behaves.) In particular, I think it would be nice to be able to
;; navigate both backwards and forwards. See comments at the
;; beginning of the section "Forms to fill in" below.
;; Another feature that would be useful to emulate would be that
;; provided by address@hidden', which allows one to put
;; braces around things already in the buffer.
;; (defun address@hidden (string &optional arg)
;; (if arg
;; (progn
;; (setq arg (prefix-numeric-value arg))

;;; Forms to fill in:
;; By a "form" I mean something that is designed for entering data
;; into. For example, if a variable has a subscript "form", the data
;; it is looking for is the expression giving the value of the
;; subscript. The simplest form in LaTeX is probably "$$", which asks
;; you to fill in some math expression. Most of the forms here take
;; one argument, but some (e.g. `austex-langle-rangle', `austex-frac')
;; take two -- of course, you are free to leave any of the forms blank
;; and LaTeX will still work. Forms like `austex-partial-derivative'
;; _expect_ to take a variable number of data (1 or 2).
;; If you want to be _literal_, the various environments are also
;; forms, as is the buffer itself.
;; The LaTeX code for forms is associated with a set of regular
;; expressions that one should be able to use to decide e.g. what the
;; "next" or "previous" form insertion point is, and move the cursor
;; to that point.
;; Since forms tend to be nested, navigating forms should be similar
;; to navigating sexps. It would be nice if "next" could move you
;; "up" or "forward" depending on context, but this would also be a
;; nice feature to have for navigating sexps.
;; Note that the syntax of sexps is not quite right for us in places.
;; For example, <1000 is considered to be one sexp. I don't know if
;; this is a valid variable name in Lisp: I guess it is. But it is
;; still wrong for us.
;; I guess we could call the new sexps "texps" -- that would be funny.
;; But what is not so funny is that in order to hack these things I'll
;; probably have to read and modify the Emacs C code in syntax.c. :(
;; Luckily the sexps for LaTeX mode aren't *too* far off from how they
;; should be.
;; This isn't really the right way to accomplish what we want. We
;; don't just want the *first* match (which is found here), nor do we
;; want the *minimal* match. Instead, we want the match that makes
;; sense syntactically. Again, this is like with sexps. We find the
;; left "paren" and then skip over "paren pairs" until we find the
;; correct "right paren". This gives some clue about how
;; `austex-define-tex-form' should be defined -- it can take a MIDDLE
;; as well as an end, and the stuff in the MIDDLE you should have to
;; skip over, in addition to whatever stuff you skip over by matching
;; paren pairs.
;;
;; But in the mean time, this sort of works -- in cases where the
;; first match is the correct match, which should be the case for
;; example if you are outside of math mode and request the previous
;; piece of text that was in math mode.

;;; Commentary:
;; This file includes the bindings I use with AusTeX (see austex.el).
;; The long-term goal is to make this into an "optimal" keyboard
;; layout in the sense of Dvorak. Right now it is just a good one in
;; the sense of the default Emacs map. The bindings are built on top
;; of a Dvorak layout, and so some of them may appear awkward or
;; confusing to users of other layouts. If you are already a Dvorak
;; user, adding these bindings to your repertoire should not be very
;; hard. On the other hand, if you are not a Dvorak user and you
;; still want to use AusTeX, you have at least three options: (1) see
;; if the bindings make sense to you with your layout after all; (2)
;; port the bindings to your layout in such a way that they do make
;; sense; (3) learn Dvorak.
;; Unlike what you may be used to in Emacs, these bindings involve
;; using a lot of modifiers! It is helpful to have a sense of the
;; physical layout of modifiers on my keyboard, even if you use some
;; other layout.
;; I actually have two Xmodmap setups; I will describe the one I use
;; on my laptop first, because it turns out that I seem to spend the
;; majority of my time typing on the laptop, especially when I am
;; taking lecture notes.
;; I replaced the number row on my laptop by modifiers. The layout is
;;
;; A H S C M G A G M C S H A
;;
;; where
;;
;; A = Alt
;; H = Hyper
;; S = Super
;; C = Control
;; M = Meta
;; G = AltGr (Mode_switch)
;;
;; The reason for the choice of the order is not arbitrary. The basic
;; principle that is I want commonly-used modifiers to be reachable
;; without moving my wrists. I can reach Mode_switch, Meta, Control,
;; and Super just by extending my fingers. The middle Alt key is a
;; slightly longer reach. Hyper is again a longer reach, and if I try
;; to press outside Alt keys without lifting my hand up and moving it,
;; I definitely feel a bit tweaked in the wrist.
;; As for what happens to the numbers -- they have been moved to the
;; AltGr layer in the right hand, in a traditional "embedded keypad"
;; arrangement. In my view, a better configuration would probably
;; require a better keyboard layout to begin with and/or better logic
;; in the keyboard, together with a more robust system of modifiers
;; inside of X.
;; This setup makes the two-modifier chords Super+Control,
;; Control+Meta, Super+Meta easy to reach as well. Hyper+Super and
;; Hyper+Control aren't that bad either, but they aren't quite as
;; nice. Other two-modifier chords aren't particularly comfortable,
;; but at least it is _possible_ to enter Alt+Hyper and Alt+Super
;; (this would be much more dubious if it weren't for the extra Alt
;; keys out on the ends of the row).
;; Though three-modifier chords may seem silly, Hyper+Super+Control
;; and Super+Control+Meta are not very hard to press down using this
;; keyboard layout. I don't bind to these much yet.
;; In general, the main benefit of using modifiers (and modifier
;; chords) instead of prefix keys is *speed*. It takes less time, for
;; example, to press C-n than it does to press C-c n. Sometimes
;; keypresses within the same modifier can be faster than you'd
;; expect, e.g. C-t C-t or G-. G-, (i.e., Up followed by backspace,
;; according to my Xmodmap).
;; Single keypresses tend to be the fastest, then single modifiers
;; plus single keys, then two modifiers plus single keys, then a
;; prefix key followed by a single key.
;; A time-savings is also afforded by finding the keys right where you
;; seek them. This is not quite the same as knowing the keyboard
;; layout: it also means that the layout should have some internal
;; logic that is easy to understand. Subjectively, the Dvorak layout
;; seems to be quite good in this regard. One goal for this file is
;; to map out some of the psychological space behind the act of typing
;; math.
;; The second Xmodmap file I use is the one I have set up for typing
;; with my Kinesis Classic keyboard. It is similar to the one I use
;; with my laptop's keyboard, but because the Kinesis keyboard comes
;; with an extra row of easy-to-reach keys below the standard four
;; rows, it is not necessary to replace the number row with modifiers.
;; This is the main difference between the two Xmodmap files. Because
;; I don't have to remap the number row, I don't use an embedded
;; number keypad approach with this keyboard, instead, I have two
;; symmetrical "editing" keypads. Because the extra fifth row has
;; only four keys for either hand, I do not bind the Alt modifier in
;; the same place with this Xmodmap file (rather it is bound to one of
;; the Kinesis "thumb keys").
;; There seems to be some risk associated with trying to share
;; something as "personal" as a keyboard layout. However, I think
;; I've put enough work into these bindings to make them worth sharing
;; with anyone who's interested. I've reduced the risk by not
;; including all of my bindings! For anyone who is _really_
;; interested, the rest of the bindings (and various nonstandard
;; functions that are bound) are available on my website. Oh yes, and
;; finally, the xmodmap files described above are also available on my
;; website.

;; This is a very long variable definition...
