hls does not work in the ghcup-hs codebase

[jneira]

• As reported by @hasufell here: https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/286hls does not work in lib/GHCup.hs(f.e.) from our beloved cousin project
• I tried in windows and i got the ide features in some utility modules, i have to check it which one
• We should recollect the usual logs as described https://haskell-language-server.readthedocs.io/en/latest/troubleshooting.html#troubleshooting-the-server

For example GHCup.Utils.Prelude works in my windows 10, with ghc-9.0.1

Note the error about hs-boot file

[pepeiborra]

Is this with HEAD or 1.4.0?

Mine is 1.4.0, just installed with ghcup. Posting the log of

and haskell-language-server-wrapper -d .\lib\GHCup\Utils\Prelude.hs is succesful, without mentioning the boot module

Ah, I've also seen that error recently! Something is up with hs-boot files. I just fixed it by getting rid of my module cycles D:

[jneira]

What a coincidence 1.5.0 is failing in hs-boot files for ghc and 1.4.0 also fails in hs-boot for ghcup, but no for ghc 😵

[hasufell]

It seems this is related: https://gitlab.haskell.org/ghc/ghc/-/issues/1012

It's a combination of boot files and template haskell.

Here's a fix: https://gitlab.haskell.org/haskell/ghcup-hs/-/commit/6073ebe4764828f668049a10f6a80b67d8d2646e#note_406582
Maybe someone wants to investigate what's actually going on there?

[michaelpj]

Is this still happening?

[fendor]

I presume it is not happening any more 🙃
