Octave vs. Objective-C

[Søren Hauberg]

Hi All

I use gedit for all of my editing needs (thanks for creating an editor
that is powerful yet easy to use), which includes editing files for GNU
Octave. Script files for Octave uses the .m extension, which also seems
to be used by Objective-C. Every time I open a .m file it seems that
Objective-C wins and gets to highlight the file.

Is there something I can do to ensure that by default Octave syntax
highlighting is preferred over Objective-C highlighting?

Thanks
Søren

We use the shared mime type database for detecting the type of a file.
In gtksourceview, first the glob specified by the language files is
matched to the filename. Then if there are more than 1 matches, the
mime-type is checked. In the case of octave and obj-c, they both have
the same globs in gsv and in the mime database. So the way they can be
differentiated then is only by the mime magick header detection, which
means if the file starts with either 'function' or '%' it is detected as
octave, but otherwise it seems it's obj-c.

You can always just remove the glob from the obj-c language file
(/usr/share/gtksourceview-2.0/language-specs/objc.lang). That should
make sure .m files are always recognized as octave highlighting.

Ahh, I see. I guess this is a bug in the Octave .lang file as it should
also recognise '#' which is the default comment-marker. We have a guy
working on improving the .lang file, so I'll just have him fix this.

I guess this is an approach, but I do fear this will cause problems when
I upgrade my OS.

Thanks,

No, it's not in the lang spec, but in the mime spec.

Yeah well, it's a small thing really. I didn't say it was a permanent  
solution, but at least
you'll have the immediate problem fixed for yourself.

Ahh, that makes sense. I've filed a bug report on this
