Haskell LSP autocompletion not working

Open KorribanMaster opened this issue 3 years ago • 8 comments

Summary

Openin a new or existing haskell file there is no completion from LSP instead there are constant error messages in the statusbar.

Reproduction Steps

I tried this:

asciicast

  1. Creating a new haskell file hx -vvv some.hs
  2. Start typing e.g. import XMon
  3. Get error message LSP: no handler for: STextDocumentDidChange\n"

I expected this to happen:

  • Completion working normally

Instead, this happened: 3. Get error message LSP: no handler for: STextDocumentDidChange\n"

This looks like an issue with your installation of HLS.

These lines are printed to the log by the language server (it is printing these to stderr):

Failed to find a HLS version for GHC 9.2.5
Executable names we failed to find: haskell-language-server-9.2.5,haskell-language-server

It looks like the wrapper is looking for HLS for GHC 9.2.5 but can't find it.

Hey Thanks for your response I'm Going to look into it

KorribanMaster avatar Nov 14 '22 08:11 KorribanMaster

what server version are you using? judging by the release description hls 1.8.0.0 does not support ghc 9.2.5

cr4zsci avatar Nov 18 '22 07:11 cr4zsci

I am a heavy Haskell user and I've never ran into this. I would check that you can build files with haskell-language-server foo/bar.hs in your terminal first.

What version of hls do you use? ghc version? I have problems with 1.8.0.0 and helix editor, But 1.7.0.0 works fine.

My problem is solving after adding system-ghc: true to stack.yaml. It is a bug of hls when stack project have ghc 9.0.2.

cr4zsci avatar Dec 05 '22 09:12 cr4zsci

Reinstalling ghc/haskell language server fixed the issue for me. Going too close this issue
