Languageclient-neovim: LanguageClient does not work with haskell-ide-engine.

[Avi-D-coder]

Summary

Language client produces timed out waiting on channel with haskell-ide-engine.
latest haskell-ide-engine works on vscode, but not with LanguageClient-neovim.

Reproduction

NVIM v0.3.0
LanguageClient 0.1.87
haskell-ide-engine Version 0.2.0.0, Git revision 92d3e8a720df43ab8212f09340f1a732079a09cb (1486 commits) x86_64 ghc-8.2.2

min-init.vim + \ 'haskell': ['hie-wrapper'],

```cd tests/data/sample-hs/
nvim main.hs

Add `one = 1`.
Move cursor over `one` `:call LanguageClient#textDocument_rename()`
Notice it takes awhile for dialog to pop up.
Rename `one` to `ones`.
notice `hie sub-process` consume small amount of CPU.
Wait.
`Error handling message: timed out waiting on channel`

It looks like it is simply the language server timed out when processing the request. Please try increase the timeout setting.

[Avi-D-coder]

I tried let g:LanguageClient_waitOutputTimeout = 60. No luck. Lint errors also don't work with hie. Everything works with rls.

[autozimu]

Might be related to this one https://github.com/autozimu/LanguageClient-neovim/issues/464

[gleachkr]

Have you set hie-wrapper to use STDIO as transport, and also set the project root?

If not, the instructions at https://github.com/haskell/haskell-ide-engine#using-hie-with-neovim might be helpful.

[Avi-D-coder]

Thank you 'haskell': ['hie-wrapper', '--lsp'], fixed it.
