Why the snippet doesn't expand?
Make sure you've opened abbrev-mode for your current major-mode. You can enable abbrev-mode globally by:
(setq-default abbrev-mode t)
Or you can enable abbrev-mode for some particular mode. E.g. for c-mode:
(add-hook 'c-mode-hook
'(lambda () (abbrev-mode 1)))Does it support Emacs 21?
It is developed under Emacs 23 and (hopefully) capable to Emacs 21. You need to add the definition of looking-back from Emacs 22 if you are using Emacs 21:
(defun looking-back (regexp &optional limit greedy)
"Return non-nil if text before point matches regular expression REGEXP.
Like `looking-at' except matches before point, and is slower.
LIMIT if non-nil speeds up the search by specifying how far back the
match can start.
If GREEDY is non-nil, extend the match backwards as far as possible,
stopping when a single additional previous character cannot be part
of a match for REGEXP."
(let ((start (point))
(pos
(save-excursion
(and (re-search-backward (concat "\\(?:" regexp "\\)\\=") limit t)
(point)))))
(if (and greedy pos)
(save-restriction
(narrow-to-region (point-min) start)
(while (and (> pos (point-min))
(save-excursion
(goto-char pos)
(backward-char 1)
(looking-at (concat "\\(?:" regexp "\\)\\'"))))
(setq pos (1- pos)))
(save-excursion
(goto-char pos)
(looking-at (concat "\\(?:" regexp "\\)\\'")))))
(not (null pos))))If there's still problems, please go to The general discussion group.
