Aliases update on rules_haskell side.

[kczulko]

Describe the bug

I think that this change tweag/rules_haskell#1636 can introduce problems on gazelle_cabal side.

To Reproduce

Use latest rules_haskell (at least those version which contains #1636) together with gazelle_cabal.

References to repository dependencies may contain leading colons, e.g. @stackage//:base instead of @stackage//base

Expected behavior

@stackage//base instead of @stackage//:base

Environment

• OS name + version:
• Version of the code:

Additional context

It should be simple adjustment of rel method

gazelle_cabal/gazelle_cabal/dependency_resolution.go

Line 156 in 0423eb4

func rel(lbl label.Label, from label.Label) label.Label {

Not objecting to this, but just to clarify.@stackage//:base should still work. Did you encounter issues with this?

@aherrmann
No I didn't check that and thanks for the clarification! I thought that it might be like that (rules_haskell preserves compatibility). I'll check it.

Looks like with cabal 3.8.1.0 we have some kind of a "full" support for public sublibraries.

Till now it's a work-in-progress on the hackage side but let me refer to its handler here: haskell/hackage-server#1119
