github.com/MarcWeber/vim-addon-haskell: Provides simple compile in background quickfix implementation with auto reconfiguring of your cabal project. It also supports multiple cabal configurations vim-addon-async is an alternative async implementation for Vim based on client-server which could be used to implement accessing ghci in some ways. It already implements python/ruby REPL with Vim completion. Would be some work, though. Vim occasionally crashes, too. Note: vim-addon-manager is a close competitor to vundle, see http://vim-wiki.mawercer.de/wiki/topic/vim%20plugin%20managment.html Note2: On Mailinglists you should always bottom quote which also means - delete text you don't reply to ! Even Windows users can do so comfortably using Shift-Ctrl-END Del. I don't know about current state of scion. In the past for older ghc's there was an implementation for Vim, too. Marc Weber
