Mustache is a functional(?) template engine, written in Ruby by GitHub’s defunkt. Put other things aside, I like the name mustache, and that’s the main reason I looked into the source. Then I found the awesome compile algorithm, the creative approach makes me more enjoyable in working with Mustache.
I like Vim too. So I grabbed mkd.vim, and created mustache.vim side by side. It’s not evolutionary, but will certainly make you a little enjoyment.
Here you go, mustache.vim.
