I don't use "auto-insert", but I think I can help.

What you need is (from elisp manual: Regexp Backslash):

`\''
     matches the empty string, but only at the end of the buffer or
     string being matched against.

You would use it like that:

(define-auto-insert "\.c\\'" "c.c")
(define-auto-insert "\.tex\\'" "latex.tex")

Note that the backslash in `\'' must be quoted inside the string
delimiters - otherwise it would act as a quoting character on the
following character.

See (elisp) Regular Expressions for reference.  Please also have a look
at the definition of `auto-insert-alist' (this is the list that
`define-auto-insert' manipulates) for more examples.  Note that you can
also "match" the major mode instead of the file name.  I.e., something
like that should work as well:

(define-auto-insert 'latex-mode "latex.tex")

auto-insert-mode: define-auto-insert condition problem

[Zhiming Wang]

To use the auto insert mode, I have the following lines in my .emacs file:

(require 'autoinsert)
(auto-insert-mode)
(setq auto-insert-directory "~/.mytemplates")
(setq auto-insert-query nil)
(define-auto-insert "\.c" "c.c")
(define-auto-insert "\.tex" "latex.tex")
;;; other templates...

This works fine when I create .c file, .tex file, etc. However, when I create files with extensions beginning with .c, .tex, etc. templates are also loaded. For instance, when creating foo.cpp, the c.c template is automatically loaded, which is not expected. Noticing this behavior I tried .text, and latex.tex template is loaded.

So, is there any way to strengthen the define-auto-insert CONDITION so that auto insert is activated only upon the exact extensions?

Thanks,
Kevin

P.S. Here is the documentation of define-auto-insert in 23.4.1:

define-auto-insert is a compiled Lisp function in `autoinsert.el'.

(define-auto-insert CONDITION ACTION &optional AFTER)

Associate CONDITION with (additional) ACTION in `auto-insert-alist'.
Optional AFTER means to insert action after all existing actions for CONDITION,
or if CONDITION had no actions, after all other CONDITIONs.

"\.c" should be "\\.c\\'" and "\.tex" should be "\\.tex\\'"
