Support GHC 9.6 #103

Closed avdv closed 9 months ago

avdv commented 10 months ago

~Note, this is based on PR #102~

I did run cabal test with GHC 9.2.8, 9.4.6 and 9.6.2.

Note: using this with proto-lens-protoc, results in an Access Violation on Windows:

blackgnezdo commented 10 months ago

Thanks for the change. I took it for a spin with 9.6.3. As you noted cabal test works fine. Sadly stack test is still broken. I pushed a couple of quick commits on top of your change to https://github.com/blackgnezdo/ghc-source-gen/pull/new/ghc-9.6

The errors I'm getting now are:

Stack has not been tested with GHC versions above 9.4, and using 9.6.3, this may fail
Stack has not been tested with Cabal versions above 3.8, but version 3.10.1.0 was found, this may fail

Is there any progress on merging this PR or otherwise introducing GHC 9.6 support on master? This patch is required for ghc-source-gen to build with GHC 9.6.3 on Arch Linux.

avdv commented 9 months ago

Thank you @blackgnezdo for starting to fix the stack tests. I have added stack configs for GHC 9.4 and 9.6 and also fixed ghc-show-ast.

I have made warnings for unused and dodgy imports non-fatal, this could be cleaned-up if needed.

I also added a CI config on my dev branch, here's the CI run: https://github.com/avdv/ghc-source-gen/actions/runs/7273133498

blackgnezdo commented 9 months ago

@avdv I'd also happily take your CI config commit instead of the existing CI which doesn't seem to work.

I don't see a strong reason to build anywhere outside of ubuntu given the kind of code this project has.

blackgnezdo commented 9 months ago

@jinwoo if you think this looks good, maybe merge it?

jinwoo commented 9 months ago

Thanks!

avdv commented 9 months ago

Thank you for merging!

Regarding CI, it seems it is indeed kicked off and at least jobs for 9.0 and 9.2 were green: https://app.circleci.com/pipelines/github/google/ghc-source-gen/256/workflows/f5ee0484-3828-43e5-9480-c539ab362ba7

If you would like me to add my Github Actions CI config, I'd be happy to create a PR.

jinwoo commented 9 months ago

Thanks, @avdv . @blackgnezdo already added GitHub Actions CI with https://github.com/google/ghc-source-gen/pull/107.
