Cabal Configuration Format๐Ÿ”—

.cabal files use a special format to specify package configurations.

  • Docs: Official documentation on the package description format.
  • CHANGELOG: Package description format specification history.
  • Minimal cabal files: Explanation of the minimal possible cabal configuration.

Useful information on various Cabal components. These could be useful blog posts on specific features, or description of handy parts of the Cabal specification.

  • Common Stanzas: Blog post about Cabalโ€™s common stanzas feature.
  • Multiple Libraries: Blog post about Cabalโ€™s multiple libraries feature.
  • Foreign libraries: Blog post about Cabalโ€™s foreign libraries feature.
  • Foreign libraries example: Example usage of foreign libraries.
  • source-repository-package: Specifying packages from remote version control locations (e.g.ย how to use GitHub dependencies in the Cabal packages).
  • cabal gen-bounds: A command to generate lower and upper bounds for dependencies in the .cabal file.
  • cabal-bounds: A command line program for managing the bounds/versions of the dependencies in a cabal file.
  • cabal-cargs: A command line program for extracting compiler arguments from a cabal file.
  • Mix-ins: Usage of the Cabalโ€™s mixin feature to replace default Prelude.


Backpack is a feature that allows implementing mix-in libraries in Haskell. Mix-in libraries can have signatures which permit implementations of values and types to be deferred, while allowing a library with missing implementations to still be type-checked.

Official documentation๐Ÿ”—





It is recommended for Haskell packages to follow PvP โ€” Package versioning Policy.
