Support for errors.haskell.org?

[danwdart]

Describe the solution you'd like

I'm not sure if it's out of scope, but would it be a good idea to have this extension support errors.haskell.org?

I could ctrl-click on an error code and it would show me a little window to explain what the error means, and allow me to go further and open it in a new tab or browser window if I wanted.

Describe alternatives you've considered

It could be a different repo if it's completely out of scope. I've not made these plugins before.

Hi!

I think that's a good idea. Do you have any specific errors in mind, or some interaction?

[danwdart]

I mean that if you hover an error code and click, it could look that error code up in a side pane, full tab or as if it's a link by prepending https://errors.haskell.org/messages/ to it. I think they're all doable, with a bit of lookup logic.

I suppose a setting would be used to specify the action of clicking the error, I think a side pane would be a good setting to default to.

So e.g. you get GHC-09009 in a terminal, hover and click and you get a side pane with the information from https://errors.haskell.org/messages/GHC-09009/ inside it.

IMO, this requires:

1. ghc9.6+
2. Update lsp to support code description

Yeah, the suggestions are not necessarily in the scope of vscode-haskell. However, I am confident, there are use-cases for us, too... Better error communication, one where we have control over the rendering, sounds very promising to me.

VSCode haskell does some of its own shenanigans like downloading and parsing https://github.com/haskell/ghcup-metadata/blob/develop/hls-metadata-0.0.1.json

This isn't done by GHCup, so may be useful to have its own error scope.
