HIE unresponsive with vim and atom

[xsebek]

I have vim¹ set up with LanguageClient-neovim and HIE does not seem to respond, although it is running².

VIM 8.1
GHC 8.6.4
HIE 0.10.0.0
macOS 10.15

Also:

apm  2.4.3
atom 1.40.1
atom-ide-ui 0.13.0
ide-haskell-hie 0.12.0
language-haskell 1.19.1

I am not savvy enough in vim to deduce how to pass hie-wrapper options (like where to log) through LanguageClient-neovim, so #1090 did not help me.

I tried to set it up with Atom, but it does not do anything? I specifically selected log to /tmp/hie.log but no log was produced 😢 A custom shell script hie-wrapper with all the flags on also does not produce any log file.

Trying things from the `LanguageClient_contextMenu`

1. Type Definition

   [LC] timed out waiting on receive operation
   

2. Code Action

   [LC] timed out waiting on receive operation
   

3. Workspace Symbol

    [LC] [Error] haskell-lsp:no handler for. Object (fromList [("jsonrpc",String "2.0"),("params",Object (fromList [("query",String "")])),("method",String "workspace/symbol"),("id",Number 13.0)])
   

4. Rename

   [LC] timed out waiting on receive operation
   

5. Definition

   [LC] timed out waiting on receive operation
   

6. References

   [LC] timed out waiting on receive operation
   

7. Formatting
   ???
8. Range Formatting
   ???
9. Document Highlight
   ???
10. Signature Help

    [LC] [Error] haskell-lsp:no handler for. Object (fromList [("jsonrpc",String "2.0"),("param...acter",Number 4.0)]))])),("method",String "textDocument/signatureHelp"),("id",Number 5.0)])
    [LC] timed out waiting on receive operation
    

11. Hover

    [LC] timed out waiting on receive operation
    

12. Document Symbol

    [LC] timed out waiting on receive operation
    

13. Implementation

    [LC] [Error] haskell-lsp:no handler for. Object (fromList [("jsonrpc",String "2.0"),("param...er",Number 28.0)]))])),("method",String "textDocument/implementation"),("id",Number 10.0)])
    [LC] timed out waiting on receive operation
    

Maybe some of the timeots were in fact timeots of the previous operation, hard to say without log file.

My current vim settings

Plugin 'autozimu/LanguageClient-neovim'
set runtimepath+=~/.vim/bundle/LanguageClient-neovim
let g:LanguageClient_serverCommands = { 'haskell': ['hie-wrapper'] }
let g:LanguageClient_loggingFile = expand('~/.vim/LanguageClient.log')

Footnotes

1. neovim does not solve the problem - I tried 😉 ↩

2. when I modified LanguageClient_serverCommands to 'haskell': ['hie-wrapper -l "someLogFileInVimFolder"'] it did explicitly say that no server was running for haskell, so I guess it was running otherwise. Also it spits out errors (when used wrong?) sometimes, eg with Workspace Symbol. ↩

While I can not help you with vim, I want to mention, that your HIE version is not up-to-date, so maybe upgrading fixes it.
You can also try to run the func-test-suite in hie and see if everything works as intended: cabal v2-run test:func-test, or stack exec haskell-ide-engine:test:func-test, assuming you built the test-suite before that. Dont forget to use the appropiate ghc version and supply the correct --stack-yaml flag!

Thanks @fendor, it took me a while but I am now living happily again in New Cabal land.

The integration with editors is still not smooth, but I believe that is not a fault of HIE 🙂

@Arkemyr so could we close the issue?
