Vim(compiler):E666: compiler not supported: ghc

[o-sam-o]

I am using Janus on OSX

I install Haskell on my machine from the following site : http://hackage.haskell.org/platform/

I have added the following line to my ~/.vim/Rakefile

vim_plugin_task "haskellmode-vim",  "https://github.com/lukerandall/haskellmode-vim.git"

I have added the following lines to my ~/.vimrc.local

" Haskell Config
au BufEnter *.hs compiler ghc

let g:haddock_browser = "open" 
let g:haddock_browser_callformat = "%s %s"

When I open a hs file I see the following error message

Vim(compiler):E666: compiler not supported: ghc

Please help.

I've only seen this error when the haskellmode plugin has not been loaded at all, so I'm assuming that's the issue. Did the plugin definitely download successfully from Git?

When I ran Janus's rake I saw the following output

****************************************
*      Installing haskellmode-vim      *
****************************************

git pull
Already up-to-date.
cp -RfL autoload/* /Users/sam/.vim/autoload/
cp -RfL doc/* /Users/sam/.vim/doc/
cp -RfL ftplugin/* /Users/sam/.vim/ftplugin/

So Janus wasn't copying the complier directory, I updated the Rakefile to copy the directory and now it works. Thanks.

Is the complier directory a standard vim dir? Should I submit a patch to Janus?

[lukerandall]

The compiler directory isn't typically used by Vim plugins (afaik), which is probably why it was omitted. I'd say it's worth submitting a patch for Janus as it's something that should work, unless they have specific reasons for not wanting to support it.
