Here is a sample code that works with emacs22 in fundamental or tex mode.
It expands \med into \medskip.
(progn
(clear-abbrev-table my-table)
(define-abbrev-table 'my-table '(
("success" "success again")
("\\med" "\\medskip")))
(setq local-abbrev-table my-table)
(setq abbrev-mode t)
(setq words-include-escapes t))
Unfortunately, it does not work anymore with emacs23.
I tried tweaking the new :regexp property to no avail.
(abbrev-table-put my-table :regexp "\\<?\\(\\\\?\\w+\\)\\W*")
I also tried
"\\(\\(\\\\\\|\\<\\)\\w+\\)\\W*"
"\\(\\(\\<\\|\w\\)\\w+\\)\\W*"
"\\(\\<?\\\\?\\w+\\)\\W*"
"\\(\\\\?\\w+\\)\\W*"
The closest I came is "\\(\\\\\\w+\\)\\W*"
that expands \med but, of course, not success.
What am I doing wrong here ?
BTW, isn't there a typo in the manual ?
The default regexp given there (36.8 Abbrev Table Properties)
is "\\<\\(\\w+\\)\\W" and does not seem to work, but the one that comes with
the definition of define-abbrev-table is "\\<\\(\\w+\\)\\W*" (and it works)
