One command does it all:
curl -o - https://raw.githubusercontent.com/begriffs/haskell-vim-now/master/install.sh | bashIn less than ten minutes your Vim will transform into a beautiful
Haskell paradise. (Don't worry, it backs up your original
configuration.) It also builds all necessary support binaries
including codex, hscope, ghc-mod, hasktags, hoogle and more.
No more wading through plugins trying to make them all work together. In ten minutes you will have a fully functional Vim that looks great and lets you
- inspect types
- evaluate Haskell
- lint and check
- manipulate tags
- hoogle lookup
- pointfree refactor
- tab compelete
- unicode symbols
- highlight DSLs
- work with git
See this wiki page for tips on fixing installation problems.

(If you prefer to restore the default screen redraw action of C-l
then add unmap <c-l> to your .vimrc.local)
After installing this configuration, your .vimrc and .vim will
be under version control. Don't alter them, add your own settings to
~/.vimrc.local instead and your additions will be loaded.
