Vim: Syntax file not loaded automatically

Question

My ~/.vimrc contains the following line:

au BufNewFile,BufRead *.fsh,*.vsh setf glsl

My ~/.vim/syntax directory contains glsl.vim that works if loaded manually (:setf glsl in Vim), but it doesn't load automatically when editing a file with those extensions. How do I get syntax highlighting for those files automatically? Syntax highlighting works for other files as usual. My Vim version is 7.4 running on Linux Mint.

This might be a shot in the dark but: have you tried using the extended form set filetype=glsl instead of setf glsl? — Nadir Sampaoli

@Nadir Sampaoli: That is not an "extended form," it is a different command. See :help :setf. — benjifisher

@SurvivalMachine: What happens with :e foo.fsh and then :verbose set ft?? How about :verbose au BufNewFile *.fsh? — benjifisher

I don't think that line can be in your ~/.vimrc. Due to loading order, it may have to be in ~/.vim/filetype.vim instead. Try putting this into that file:

augroup filetypedetect
  au BufNewFile,BufRead *.fsh,*.vsh setf glsl
augroup END

VIM commands can be in .vimrc. That's the whole point of its existence.

Vim commands can be in .vimrc, but they can also be elsewhere. File type commands are supposed to be in filetype.vim, and I've had issues trying to force it into .vimrc in the past. This is because load order can matter, as implied by this question.

Tried adding it to /usr/share/vim/vim73/filetype.vim. After I put au BufNewFile,BufRead *.fsh,*.vsh setf glsl in ~/.vim/filetype.vim, it worked.
