DISCONTINUED
I haven't used Vim or Twig in a long time and so haven't made time to keep this up-to-date.
More recent development has taken place at https://github.com/lumiliet/vim-twig
Supports Twig PHP templates http://www.twig-project.org/
Based on Jinja2 syntax highlighting by Armin Ronacher
This scripts bundles is compatible with vim-addon-manager
You can also install (locally) using Pathogen:
$ cd .vim/bundle/
$ git clone <repo>- Also supports html syntax highlighting
- Re-based the syntax highlighting to properly support all tags
- Added support for .html.twig files
