Emacs change file extension - mode association

Question

My Emacs opens .m files in ObjC mode. However I want to open them in Octave mode. I have already added to the .emacs file:

(autoload \'octave-mo         


        

Answer 1

Fortunately everything is working now and unfortunately I don't remember how I fixed it :) Maybe there was an error in my .emacs earlier. This is the more correct code:

(add-to-list 'auto-mode-alist '("\\.m$" . octave-mode))

Autoloading is unneeded in recent versions; if you do need to enable it, note that "octave-mode" is not a typo.

(autoload 'octave-mode "octave-mod" nil t)
