Dear GHC devs, I am currently working on my own fork of GHC ( https://gitlab.haskell.org/trupill/ghc), and as part of it I need to do some changes to the Cabal and haskeline libraries. However, since they are in submodules, I am not sure about how I can commit those changes, share them with others, and rebase my changes against the current HEAD for these submodules.

You can push wip/ branches to the GHC mirrors of these submodules where they can be picked up by CI. Specifically, git@gitlab.haskell.org:ghc/packages/Cabal git@gitlab.haskell.org:ghc/packages/haskeline Just make sure that your branch name begins with `wip/` and you should be able to push. Do let me know if there are further questions. Cheers, - Ben
