auto-mode-alist - recognize prefix instead of sufix?

auto-mode-alist - recognize prefix instead of sufix?

[Christian Herenz]

Hi,

is it possible to use a major-mode on files with a certain prefix?
I know that I can do something like this:

(setq auto-mode-alist (cons '("\\.html$" . 
html-helper-mode)auto-mode-alist))

But what about opening files like foo.comments, foo.examples and so on 
in a special mode?

Thanks in advance...

Christian

I never tried, but from the documentation it looks perfectly possible. 
Have you tried to use a regexp like "^foo\." ?

It is definitely possible, but the auto-mode-alist regexp is matched
against the whole file name sans backup suffix i.e.
(file-name-sans-version buffer-file-name).

So the regexp should be something like "\\(\\`\\|/\\)foo\.[^/]*\\'"

I dont get it working :(

I have files called:
nb_edit-newentry-*************.txt (where stars numbers and letters).

What would be a correct Regexp for that?

something as 
nb_edit-newentry-.*\.txt
should suffice with a direct command such as query-replace-regexp
if you need to write this regexp in a el-file double the \
