org-mode not recognized as major mode

org-mode not recognized as major mode

[Henri Fischer]

Hi All,

First of all my best wishes for 2009!!!!

I have two questions.

My Emacs doesn't identify files ending with "*.org" as org-mode files.
I don't want to use a mode identifier at the beginning of my org
files. Does this mean I have to edit my ldefs-boot.el and loaddefs.el?
If org was already part of my Emacs (Carbon), then why doesn't it
recognize the file extension "*.org"?

Kind regards,
Henri

Same to you!

You can add a matching filename regexp to auto-mode-alist:

    (add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))

Maybe without the \ \ ' ?  Or is that a special thing?

Oh, I see that lots of modes use that.  Must be a special thing,
instead of $.  Never mind :).

The \' atom matches with zero-width at the end of string or end of
buffer. As you know $ is a zero-width atom that matches at the end of
line. In theory a filename may contain newlines (in Linux filesystems at
least) and in such situations the $ atom wouldn't necessarily match the
end of the whole filename string.
