vim-haskellmode and hsenv

Question

I've been using hsenv (with great success!) to deal with the usual cabal dependency issues.

Its terrific, but there is one glitch I can't get around: how to persuade the (also excellent!) vim-haskellmode to use the environment variables set by hsenv -- namely the paths to GHC, cabal database and so on when compiling, generating tags etc.

Does anyone know how to solve this problem?

Answer 1

Sorry, hit the wrong button -- I should be asking questions about how to use SO instead :)

Anyways, an even better trick is to put this into the .vimrc

let g:ghc=system("which ghc") 

This way (assuming that g:ghc gets bound when you run vim) it will pick up whichever ghc is being currently used (by hsenv).

Answer 2

One, simple solution is to hack one's .vimrc so that

let g:ghc="/path/to/hsenv/ghc"
