haskell-mode not running the binary haskell-language-server

dewijones92 commented 2 years ago

Thank you for the bug report

[X] I am using the latest version of lsp-mode related packages.
[X] I checked FAQ and Troubleshooting sections
[ ] You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

Thanks for this amazing project 😊 I am banging my head against a brick wall here 😔 When I run "haskell-mode" I expect it to run the associated language server. But it is not.

Steps to reproduce

Open a haskell project
Run in emacs haskell-mode

Expected behavior

Spacemacs should run haskell-language-server

Which Language Server did you use?

haskell-language-server

OS

Linux

Error callstack

To me it sounds like your project is problematic for the server, @michaelpj is more familiar with haskell ls.

michaelpj commented 2 years ago

Yes, please consult the HLS troubleshooting page and open an issue if that doesn't help: https://haskell-language-server.readthedocs.io/en/latest/troubleshooting.html

yyoncho commented 2 years ago

Closing the issue for now, please reopen if you discover something to be fixed on lsp-mode side.

@michaelpj @yyoncho Hello, thanks for your response. It doesn't seem to be a problem with the server side of things. The process does not exit when running on the command line.

If you are seeing this in a terminal, you probably should have run WITHOUT the --lsp option!

The problem is seemingly only apparent when trying to get emacs to work with it. It seems to be a problem client-side. Any suggestions? thanks :)

yyoncho commented 2 years ago

@dewijones92 the server does not infer project dir - it receives it through initialize message.

is there a working combination of a stack project and HLS you can link me to? ideally where the versions are explicit thanks v much

michaelpj commented 2 years ago

@dewijones92 please follow the troubleshooting guide I linked.
