hackage-revdeps

Command-line tool to list Hackage reverse dependencies.

It is different from how Hackage itself tracks them: this tool accounts for all package components, including tests and benchmarks, and counts dependencies only across the latest releases. The approach is roughly equivalent to what packdeps.haskellers.com does.

Changes

0.4.1

Do not filter dependencies based on buildable field in Cabal file, it’s unreliable.
Support cabal-install-3.18.

0.4

Yet another API overhaul, extending it with ExtractDependenciesMode argument.
Collect dependencies from build-tool-depends too.
hackage-revdeps-history now plots results.

0.3

Another API overhaul.
Enable seamless processing of 01-index.tar.gz as well as 01-index.tar.

0.2

Overhaul the API.

0.1.1

Replace dependency on cabal-install-parsers with cabal-install proper.

0.1

Initial release.
