ormolu fails to run

[kozross]

When I try Neoformat ormolu, I get the message that ormolu failed to run. When I run ormolu manually from the command-line, this works without issue.

This didn't show up until I tried the latest ormolu (version 0.0.5.0) - on all previous versions, this worked fine.

I was having the same issue (except I haven't tried ormolu versions prior to 0.0.5.0) and managed to solve it with the following config:

let g:neoformat_haskell_ormolu = { 'exe': 'ormolu', 'args': [] }
let g:neoformat_enabled_haskell = ['ormolu']

Hope it helps!

The -p flag added here doesn't seem to exist anymore (I'm not familiar with older versions of ormolu, just getting it set up): https://github.com/sbdchd/neoformat/blob/master/autoload/neoformat/formatters/haskell.vim#L58
