'Remove redundant imports' code action not showing in neovim 0.9

[asivitz]

Your environment

Which OS do you use?
MacOS

Which version of GHC do you use and how did you install it?
9.4.7 from ghcup

How is your project built (alternative: link to the project)?
stack

Which LSP client (editor/plugin) do you use?
nvim + lspconfig (the neovim native lsp)

Which version of HLS do you use and how did you install it?
2.4.0.0 from ghcup

Have you configured HLS in any way (especially: a hie.yaml file)?
Yes, a hie.yaml

Steps to reproduce

Open a file using neovim 0.9. Add a redundant import. Ask for code actions on this line.

Expected behaviour

There is a code action to 'Remove import' and 'Remove all redundant imports', as well as 'Disable 'unused-imports' warnings'

Actual behaviour

There is only a code action to disable the warnings

Debug information

The code actions do appear under neovim 0.7. Here are RPC logs for the two versions. Looks like the request data changed a bit between 0.7 and 0.9.

Is it possible to get the request as correctly-formatted JSON? I don't know what the thing being printed by neovim is, but it isn't correct JSON.

It's not at all obvious to me what's going wrong. Can you run HLS with debug logging on? I think someone will just need to debug a bit.

[carbolymer]

I'm affected by this too. From what @asivitz posted it seems that neovim is sending a different range information? Here's the diff between 0.7 and 0.9 requests:
https://www.diffchecker.com/BE84YWxl/
The difference in range:
0.7:

range = {      end = <1>{        character = 0,        line = 8      },      start = <table 1>   }

0.9:

range = {      ["end"] = <1>{        character = 5,        line = 8      },      start = <table 1>    }

I'll try to reproduce this on my machine later.

[michaelpj]

Like I said, it's really not obvious to me what's happening here. It would help to get some proper JSON for the problematic request, and then I think someone just needs to take a look at the code and see if it's doing something silly. Debug logging may help.

[michaelpj]

For example, what on earth does ["end"] = ... mean in this context? JSON keys can't be arrays? I have no idea what this actually corresponds to. I do think there's a decent chance that neovim is sending malformed LSP requests or something.

[keithfancher]

Just popping in to say I'm still seeing this behavior on neovim 0.9.5, HLS 2.5.0.

Is this reproducible on (e.g.) VS Code? Might be the quickest way to narrow down whether it's a HLS or neovim issue...

Removing redundant import works for me in vscode.

[keithfancher]

Removing redundant import works for me in vscode.

Yup, me too. (Now that I've installed it again, heh.) Which definitely suggests it's a problem with neovim! I filed neovim/neovim#27318, cribbing the logs from @asivitz's original report. Hope that's cool!

[keithfancher]

Well, I opened a PR that fixes the issue: #4051

...but I'm not sure if it's the "right" thing to do! Meanwhile though, if you're affected by this, building HLS from the above branch should get you going again.
