Hello folks. I began project, using autotools as build system. There are 3 new file types, that need special threating: - autoconf: usually configure.ac, though i assume it could be any *.ac file; - automake: usually makefile.am, though i'm sure is all 'makefile' part is mandatory or any *.am could be threated so (remembering, that mime type system relies to content patterns as well); - m4 script: i have several *.m4 files in project dir, but autoconf is known to be derived from m4 file types with some overridements (e.g. [] instead of `'); (automake file type is in turn makefile derivation). Closer to issue. I wanted to set autoconf/automake mime types associations with emacs, which has probably the best highlighting (recognizes them independently on system when opening, unlike mousepad, which opens makefile.am as plan text file, despite of automake support presence in gtksourceview types database). Though my memory might fail, i have feeling, that other DE (kde) have some more mime types support than gtk-based. I looked to xfce4 mime editor, and there is only text/x-makefile types from all related. My question - are there some other mime file type databases besides of fdo shared-mime-types, containing extra types? If there are better placed for this question, would be great to know it.
