Hackage Release

Bump version, build, validate, tag, push, and publish a Haskell package to Hackage.

Workflow

1. Bump version in package.yaml (if using hpack) or .cabal file
2. Update ChangeLog.md with release notes
3. Regenerate cabal (if using hpack): hpack
4. Build: cabal build
5. Check: cabal check (must report zero warnings)
6. Create sdist: cabal sdist
7. Commit & tag: commit all changed files, git tag vX.Y.Z.W
8. Push: git push && git push --tags
9. Get Hackage credentials: pass show hackage.haskell.org.gpg
   • Format: first line is password, user: line has username
10. Publish package: cabal upload --publish <sdist-tarball> --username=<user> --password='<pass>'
11. Build & publish docs: cabal haddock --haddock-for-hackage then cabal upload --documentation --publish <docs-tarball> --username=<user> --password='<pass>'
