Previous meeting notes

Agenda & Notes

New items to discuss

• Recruit for this group

  • Ask CLC to have a representative?
  • We need more user opinions. E.g. search for prolific authors on Hackage. Hecate? Adam B?
  • Post monthly updates

• Rebalance meetings for task progress vs task identification

  • Don't just want to be a talking shop -- want to Get Things Done
  • Track projects in repo

• GHC-internal modules link to CLC thread

  • Lack of tooling to state/track performance characteristics
  • Ben has a patch that checks for changes in base API: https://gitlab.haskell.org/ghc/ghc/-/commits/wip/ghc-base
  • One issue with ghc-base is possible change in error messages https://gitlab.haskell.org/ghc/ghc/-/commit/fd7ac91eb5dbd061b8cb7d8ef35e90017105ea7c?page=3#5504a9447935fb91e9daad24a7c944a94fde4b60
  • Useful: module re-exports: https://gitlab.haskell.org/ghc/ghc/-/wikis/module-reexports?version_id=87060cead2ead5f654c42c070c7c6913d2bdf806
  • Should we start by moving everything or nothing from base to ghc-base?
  • Useful: deprecated exports: details here: https://gitlab.haskell.org/ghc/ghc/-/issues/4879 (this ticket points to the relevant GHC Proposal)
  • all wired-in things and known-key things live in ghc-base, so this would unlock re-installable base.
