Description
Your environment
Which OS do you use?
ArchLinux
Which version of GHC do you use and how did you install it?
9.8.2, managed via GHCup
How is your project built (alternative: link to the project)?
Just created a project via cabal init --simple, answering 2) Executable to the first and only question.
Which LSP client (editor/plugin) do you use?
Terminal Vim + YCM
Which version of HLS do you use and how did you install it?
Should be 2.9.0.1, if I understand correctly (see debug info).
Have you configured HLS in any way (especially: a hie.yaml file)?
Not that I'm aware of (and log says definitely I don't have a hie.yaml file), but please ask specific question if anything makes you think I have.
Steps to reproduce
- Initialize a project with
cabal init --simple, - add the line
f = when, - ask for
FixItonwhen, - choose 4, i.e.
import Control.Monad (when)(any other will do I guess)
Expected behaviour
import Control.Monad (when) should be added in the preamble of the file.
Actual behaviour
Expected behavior does not happen, and this error is triggered instead:
ResponseFailedException: Request failed: -32601: No plugins are available to handle this SMethod_CodeActionResolve request.
Plugins installed for this method, but not available to handle this request are:
explicit-fields does not handle resolve requests for (unable to determine resolve owner)).
hlint does not handle resolve requests for (unable to determine resolve owner)).

Debug information
This is the log of the HLS:

Hi, thank you for the bug report!
Unfortunately, I can not reproduce the described issue on GHC 9.6.6 or 9.8.2.
Perhaps something else is broken in addition?
Try running HLS with
--debugand please share the logs of HLS, showing that the CodeAction failed.The
--log-fileoption might be handy for obtaining the logs.Aster89 commentedon Dec 18, 2024
Content of the
logfile after executingis
fendor commentedon Dec 18, 2024
Can you try to execute the CodeAction in your editor while passing these flags to HLS?
Aster89 commentedon Dec 18, 2024
@fendor , would you mind clarifying which flags?
fendor commentedon Dec 18, 2024
The flags
--debugand--log-file:) If you run it in CLI mode, we can't see whether the code action execution failed in any way. So, ideally we get the logs of a real IDE run, with the additional logging output, where you try to use the code action, but HLS throws an error unexpectedly.Aster89 commentedon Dec 19, 2024
I've passed those options to HLS via the IDE (Vim+YCM); here's the log:
fendor commentedon Dec 20, 2024
Thanks! I am wondering whether this is related to #4451...
I still can't reproduce, so I guess this bug might be specific to vim and
YCM.Aster89 commentedon Dec 26, 2024
@fendor , would you mind helping understand what I should expect from HLS, in this case? I mean, how can I use it in a standalone way so that I can see what messages it sends to the IDE?
I mean,
2024-12-17T16:50:27.362922Z | Warning | No plugin handles this "codeAction/resolve" request.sounds a lot like YCM sends some request to HLS, and HLS doesn't find a plugin for it.fendor commentedon Dec 28, 2024
It looks like HLS supports
codeAction/resolve, so vim always sends acodeAction/resolverequest to HLS. However, not all plugins and not allCodeActions have an associatedcodeAction/resolvehandler. For example, if theCodeActionis cheap, there is no reason to do the roundtrip to the server.However, it looks like some clients added support for
*/resolverequests and unconditionally asks forcodeAction/resolve. HLS rejects this request in some instances, perhaps this leads to vim not applying the codefix it already has around locally.Presumably, you can tell your client to log the lsp messages. However, I am not sure how to do that with vim.
resolverequests #4473*/resolverequests #4478fendor commentedon Jan 6, 2025
@Aster89 In #4478, I implemented a fallback handler for
resolverequests. To my understanding, this should fix your issue, could you give it a try?If you are using
ghcup, then the following should work:ghcup compile hls -g enhance/plugins/handle-resolves --ghc <ghc-ver>and then make sure vim is using that binary.17 remaining items
