history

Project history and usage

stylish-haskell is a Haskell source prettifier focused on practical cleanup rather than whole-program reformatting. Its README says the tool aligns and sorts imports, groups language pragmas, removes trailing whitespace, aligns records and cases, converts line endings, and can be used as a filter in editors.

Project history

The Cabal metadata lists Jasper Van der Jeugt as author and maintainer and carries a 2012 copyright notice. The README describes the original design goal as avoiding formatters that get in the way while automating tedious import and layout cleanup.

Adoption history

The README documents installation through `stack install`, `cabal install`, Debian, Ubuntu, and Arch Linux, while the input package-manager facts also list Homebrew, Nix, Debian, and Pacman packages. It is also exposed through editor workflows including Haskell Language Server, Vim, Emacs, Atom, and Visual Studio Code integrations.

How it is used

Common usage is either project-level formatting through `.stylish-haskell.yaml` or editor-filter usage such as piping a buffer through `stylish-haskell`. The README documents a search order that checks an explicit `--config`, the current or nearest ancestor `.stylish-haskell.yaml`, the platform config directory, the home directory, and finally defaults.

Why package nerds care

Package maintainers care about stylish-haskell because it is a small CLI with predictable config discovery, broad Haskell package-manager availability, and a long life across GHC and Cabal releases. Its changelog is largely about compiler and parser compatibility, which is exactly the kind of maintenance surface Haskell packagers track.
