Is there any good Haskell indentation script for Vim?

Question

Unfortunately, the one Haskell indent script I found (by motemen) breaks when it comes to Haddock comments:

-- |Docline 1, lorem ipsum<CR>
    -- Docline 2
^^^^ - an autoindent here, wtf

Would anyone happen to know about a better alternative?

Answer 1

Okay, so after even more googling, I found this indent script:

https://github.com/kana/vim-filetype-haskell/blob/master/indent/haskell.vim

It seems to work almost perfectly (ignores if..then.. else and let). But to be honest, the fact that it doesn't break my documentation makes it good enough right now :)

Answer 2

I've no problems with haskellmode-vim

edit: FWIW, I've found this reddit thread recently. vim2hs looks nice to me, also regarding indentation.
