##Syntax Highlighting For .coffee Files in vim72

After copying the coffee.vim file into the syntax directory for your vim72 install, you have two options for enabling syntax highlighting of .coffee files

Manually

In the vim console, do:

:set syntax=coffee

Automagically

The "least intrusive" way to add syntax highlighting for .coffee files in vim72 is to create a file (named, say, filetype.vim) in your ~/.vim (or platform appropriate) folder. In it, you would put someting like:

if exists("did_load_filetypes")
  finish
end
augroup filetypedetect
  au! BufRead,BufNewFile *.coffee setfiletype coffee
augroup END

And the next time you open a .coffee file, voila!
