Import and extend GNU's descr-text.el, supporting prefix argument for C-x =
2008-05-25 Aidan Kehoe <kehoea@parhasard.net>
* descr-text.el: New.
Taken from GNU's GPLV2 version of 2007-02-14, with modifications
for XEmacs support and extensions for Unihan.txt support and
db/dbm caches.
* simple.el (what-cursor-position):
Support an optional prefix argument, as does GNU, calling
#'describe-char to giving more detail on the character at point,
notably from UnicodeData and (in our case, optionally) Unihan.txt.
* syntax.el (syntax-after):
Make this available for the sake of #'describe-char.
* mule/mule-cmds.el (iso-2022-control-alist):
Make this available, for the sake of #'encoded-string-description
and #'describe-char.
* mule/mule-cmds.el (encoded-string-description):
Make this available, for the sake of #'describe-char.
* unicode.el (unicode-error-default-translation-table):
Make this a char table of type generic, not of type char. Makes it
possible to have the relevant logic in #'describe-char reasonably
clear; also, and this is undocumented, makes it much easier to
implement #'frob-unicode-errors-region. I should document this,
and revise #'frob-unicode-errors-region.

\input /home/gd/gnu/doc/texinfo.tex @c -*-texinfo-*- @c %**start of header @setfilename ../../info/back-cover @settitle XEmacs Lisp Reference Manual @c %**end of header . @sp 7 @center @titlefont {XEmacs Lisp} @sp 1 @quotation Most of the XEmacs text editor is written in the programming language called XEmacs Lisp. You can write new code in XEmacs Lisp and install it as an extension to the editor. However, XEmacs Lisp is more than a mere ``extension language''; it is a full computer programming language in its own right. You can use it as you would any other programming language. Because XEmacs Lisp is designed for use in an editor, it has special features for scanning and parsing text as well as features for handling files, buffers, displays, subprocesses, and so on. XEmacs Lisp is closely integrated with the editing facilities; thus, editing commands are functions that can also conveniently be called from Lisp programs, and parameters for customization are ordinary Lisp variables. This manual describes XEmacs Lisp. Generally speaking, the earlier chapters describe features of XEmacs Lisp that have counterparts in many programming languages, and later chapters describe features that are peculiar to XEmacs Lisp or relate specifically to editing. @end quotation @hfil @bye
