Tech stack & purpose

Stackage is a project by Commercial Haskell that maintains stable, curated sets of Haskell packages from Hackage, organized into Nightly and Long Term Support (LTS) releases. The repository serves as the central metadata hub where package authors and maintainers can add their packages to Stackage by editing build-constraint files and opening pull requests, with packages required to build cleanly against current GHC versions and their dependencies. The Stackage ecosystem is built around the Haskell stack build tool and consists of multiple interconnected repositories including stackage-server, curator, lts-haskell, and stackage-snapshots, which together orchestrate the selection, building, and distribution of vetted package sets. The project automates snapshot creation through build processes that calculate dependency plans, verify compilability, and publish YAML snapshots frozen at specific points in time.
