No working feature using vscode and hls in wsl2, nix and devcontainer

[jneira]

• From a report in discord https://discord.com/channels/502892968475230219/503943890232016908/888674125491621918

I don't understand what's I am missing. I am in WSL2, using nix, run nix-shell just to get GHC and cabal-install, ormolu, hlint, etc. Then I run vscode-insiders inside nix-shell. Run VSCode, and it downloaded haskell-language-server based on my GHC version.

Posting the issue as i dont have any clue where the problem could come from. The server log does not seem to be erroneous but it seems it is ignoring messages from the client other than close, open and edit the file (and the lsp configuration). Regular log from plugin activity is not shown. Weird.

[Rizary]

@jneira thank you for opening an issue. I have created a minimum repro repository: https://github.com/Rizary/haskell-devcontainer.

I've tried it in my WSL2, Windows 10 (using haskell-language-server devcontainer from microsoft repo), and in my Ubuntu 20.04 Hyper-V machine without any positive result.

Is it because of my VSCode's user setting? But I doubt it.

[jneira]

Did you have the chance to try in native windows, to compare the behaviour?

[Rizary]

Yes, I did. It is working fine in native windows. Here is the log that I got from windows:

One thing that I notice is hie-bios is not loaded and running. It also still detect hls version 1.2.0.0 while I already have 1.4.0.0.

Edit: fix the log format.

[Rizary]

@jneira I think I'm done for now with devcontainer + haskell language server. It seems the problem reside somewhere inside the invocation of hie-bios, or the hls itself didn't know how to run inside vscode devcontainer.

[jneira]

@jneira I think I'm done for now with devcontainer + haskell language server. It seems the problem reside somewhere inside the invocation of hie-bios, or the hls itself didn't know how to run inside vscode devcontainer.

have you try the official devcontainer image? https://github.com/microsoft/vscode-dev-containers/tree/main/containers/haskell

[Rizary]

@jneira I did and it doesn't work either. One thing that I notices are (but need clarification):

1. When registering ide configuration, hls that doesn't work has similar output: 2021-09-21 07:11:47.9105421 [ThreadId 5] INFO hls: Registering ide configuration: IdeConfiguration {workspaceFolders = fromList [NormalizedUri (-4668498412949811645) "file:///workspace"], clientSettings = hashed Nothing}

Which is about normalizing uri. Turns out all has minus value. I've tried to read the source code, but I got lost. What I understand is hls is hashing the filePath. Maybe I'll have a look at the hls source again in the weekend.

2. There is no: 2021-09-20 13:10:40.5194621 [ThreadId 59] DEBUG hls: hlint:getIdeas:file:NormalizedFilePath "D:\\Engineer\\ubuntu2004\\rizary\\rizary-haskell\\backend\\app\\Main.hs" in the error hls.

In my understanding, the path doesn't get normalized. If it is, then it should be hlint:getIdeas:file:NormalizedFilePath "/workspace" imo.

3. There is no:

   2021-09-20 13:10:40.5214636 [ThreadId 71] INFO hls: Consulting the cradle for "backend\\app\\Main.hs"
   Output from setting up the cradle Cradle {cradleRootDir = "D:\\Engineer\\ubuntu2004\\rizary\\rizary-haskell", cradleOptsProg = CradleAction: Cabal}

4. There is no:

[jneira]

What I understand is hls is hashing the filePath

yeah, just that, the code is in the library lsp:

https://github.com/haskell/lsp/blob/ab1aec745268afadcbfe4404d61e230e4c188e98/lsp-types/src/Language/LSP/Types/Uri.hs#L46

In my understanding, the path doesn't get normalized. If it is, then it should be hlint:getIdeas:file:NormalizedFilePath "/workspace" imo.

When you say "There is no..", do you mean you see those entries in the log when using native windows but no when you use devcontainer?

D:\\Engineer\\ubuntu2004\\rizary\\rizary-haskell\\backend\\app\\Main.hs looks like a normalized file path (it has the drive in upper case, no . nor .., etc (see the code in lsp linked above to analyze what normalize does)

But i think you got the possible root cause, the workspace folder uri is not well handled and it seems hls thinks there is no haskell source code.

[Rizary]

yeah, just that, the code is in the library lsp:

https://github.com/haskell/lsp/blob/ab1aec745268afadcbfe4404d61e230e4c188e98/lsp-types/src/Language/LSP/Types/Uri.hs#L46

Does hashing into negative value matter?

When you say "There is no..", do you mean you see those entries in the log when using native windows but no when you use devcontainer?

correct.

D:\\Engineer\\ubuntu2004\\rizary\\rizary-haskell\\backend\\app\\Main.hs looks like a normalized file path (it has the drive in upper case, no . nor .., etc (see the code in lsp linked above to analyze what normalize does)

The above is the working one. In devcontainer, there is no such thing.

But i think you got the possible root cause, the workspace folder uri is not well handled and it seems hls thinks there is no haskell source code.

Yeah, but they somehow got the hie.yaml.

[jneira]

Does hashing into negative value matter?

No, it is fine

Yeah, but they somehow got the hie.yaml.

Hmm, you are right, unfortunately i have not used devcontainers so i cant confirm if they even work, will try to check it

[jneira]

There is an issue with a similiar setup in the extension repo: https://github.com/haskell/vscode-haskell/issues/501
