Error using multiple home component with cabal 3.12 prerelease in HLS Repo

[soulomoon]

Using cabal 3.12 prerelease and set up multiple home component.

I am getting this error in hls

It seems cabal v2-repl --keep-temp-files --enable-multi-repl /Volumes/src/tmp/haskell-language-server/ghcide/exe/Arguments.hs
fails on hls code base

and it is fine if we use
cabal v2-repl /Volumes/src/tmp/haskell-language-server/ghcide/exe/Arguments.hs

[soulomoon]

Probably this issue should be transferred to cabal?

A version mismatch, it is expected?🤔
The same cabal build the project just fine.

[Bodigrim]

Looks like haskell/cabal#9632, try the same workaround in cabal.project?..

[soulomoon]

Thanks, the workaround does the magic @Bodigrim

Turn out this workaround would need the pin the extact cabal version to 3.12.0+0 that shipped with the cabal-install I use https://gitlab.haskell.org/haskell/cabal/-/jobs/1848815.

allow-newer:
  *:Cabal,
  *:Cabal-syntax

source-repository-package
    type: git
    location: https://github.com/haskell/cabal.git
    subdir: Cabal Cabal-syntax
    tag : 3.12.0+0

[Mikolaj]

@soulomoon: why is the official tag 3.12.0.0 not enough? It should be. What tag/branch have you been using that did not work with the workaround?

[soulomoon]

sorry for not stating it clear, not pin to a tag is not enough, pin to tag 3.12.0.0 fix that.

[Mikolaj]

Cool! Thank you very much for the confirmation.

Another error, it is fine if I repl each file, but not when it come togather
==== update
You need to cd to ghcide to observe this.
Works fine

cabal v2-repl --enable-multi-repl /Volumes/src/soulomoonHLS/ghcide/test/src/Development/IDE/Test.hs
cabal v2-repl --enable-multi-repl /Volumes/src/soulomoonHLS/ghcide/test/exe/DependentFileTest.hs

But not

[soulomoon]

maybe when we repl both, we pick up some package that have a setup.hs mismatching Cabal with

 subdir: Cabal Cabal-syntax
    tag : 3.12.0+0

[soulomoon]

It is a dependency problem, I opened new issue to push for the update for the dependency instead
