As you might have read in my previous post, I have recently started playing around with the programming language named Twelf.
Twelf ships with a Vim mode, but unfortunately they forgot to take account of different colour schemes and it only appears to be working well with the default Vim colour scheme. I decided to rewrite the syntax highlighting files for Twelf, so that they work with the colour scheme of your choice.
Here it is. Releases are available for download from here, or you can grab the code directly off Github with
git clone git://github.com/ahf/twelf-syntax.git.
