;;; Commentary:

;; This is a new, experimental feature of eev that is not loaded by
;; default and that has been tested by very few people. I mentioned
;; it on help-gnu-emacs in this thread:
;;
;;   https://lists.gnu.org/archive/html/help-gnu-emacs/2021-12/msg00173.html
;;   https://lists.gnu.org/archive/html/help-gnu-emacs/2021-12/threads.html#00173
;;
;; Its advantages over the official input methods are:
;;
;;   1. People can learn to use this very quickly and learn input
;;      methods later - see the msg00173 above.
;;
;;   2. Each unicode character can be associated to a face and a
;;      color, like the red stars and green "«»"s used by eev:
;;
;;        (find-eev-intro "1. `eev-mode'")
;;        (find-eev-intro "1. `eev-mode'" "colored glyphs")
;;        http://angg.twu.net/eev-intros/find-eev-intro.html#1
;;        (find-eev-quick-intro "6.4. Red stars")
;;        http://angg.twu.net/eev-intros/find-eev-quick-intro.html#6.4
;;
;;   3. These faces can be turned on and off. I usually keep them on
;;      almost all the time, and turn them off only for editing Agda
;;      code.
;;
;;   4. New characters are easy to add.
;;
;;   5. Each unicode character can be associated to LaTeX code. I use
;;      lualatex most of the time but when I have to prepare a file to
;;      be uploaded to Arxiv I have to make it compilable with both
;;      lualatex and pdflatex; this file includes hacks that generates
;;      "definitions in lualatex" and "definitions in pdflatex" for
;;      all the unicode characters that have LaTeX code associated to
;;      them. See:
;;
;;        (find-LATEX "edrx21chars.tex")
;;        (find-LATEX "edrx21chars-d.tex")
;;        (find-LATEX "2021composes-hash.tex")
;;        http://angg.twu.net/LATEX/edrx21chars.tex.html
;;        http://angg.twu.net/LATEX/edrx21chars-d.tex.html
;;        http://angg.twu.net/LATEX/2021composes-hash.tex.html
;;
;;      If you just want to test this, see:
;;
;;        (find-LATEX "2021composes-hash.tex" "test")
;;        http://angg.twu.net/LATEX/2021composes-hash.tex.html#test
;;
;; The disadvantages are obvious: this is non-standard, some parts of
;; the code are ugly and need to be rewritten, some names of functions
;; and variables will change, etc, etc.

;; I needed something that was easier to understand and easier to
;; extend - in the sense of: adding new characters - than these
;; standard methods, and that would let me use one face for the
;; uppercase greek characters, another for lowercase greek, another
;; for the standard mathematical chars, and so on... so in the late
;; 90s I devised a very simple hack in which `M-,' followed by two
;; characters would "compose" these two characters according to a
;; conversion table, and I also had a very, very ugly hack that
;; allowed me to specify this conversion table, AND THE FACES, in a
;; somewhat human-friendly format, as lists of big strings and face
;; names... That implementation used alists for the conversion tables,
;; and was very hard to maintain.
;;
;; The implemention in this file is much simpler - because is uses
;; hash tables for the conversion tables, and uses a big regexp built
;; with `rx' to specify how to parse the human-readable conversion
;; tables given in big strings... and also, as a bonus, it lets me
;; specify how the special characters are to defined in LaTeX, both
;; with `\catcode' and with `\DeclareUnicodeCharacter'.
;;
;; I decided to include this in eev because it MAY be useful in my
;; next workshops on LaTeX (+ Emacs + eev): people can learn this,
;; including how to extend it, in a few minutes, and then learn the
;; standard input methods later - in more than a few minutes.
;;
;; This is very-new-ish code. Everything may change - ESPECIALLY the
;; terminology and the names of the variables and functions. I am
;; currently using these terms:
;;
;;   a "keys" means "a pair of easy-to-type characters" (that have an
;;     unicode character associated to them),
;;
;;   a "pos" means this unicode character,
;;
;;   "composes" means "all the data structures that show how each
;;      "keys" is converted to a "pos", how each "pos" is converted to
;;      latex code, which face is associated to each pos, etc, etc,
;;
;;   a "big string", or a "bigstr", is a string that may contain, and
;;     usually contains, newlines,
;;
;;   a "bigstr spec" is a big string that specifies how the "pos"s are
;;     associates to "keys", to latex code, and to faces.
