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. ### Timeline - 2012: Cabal metadata lists the project copyright and original authorship. - 2024-01-19: Version 0.14.6.0 added GHC 9.8 support according to the official changelog. - 2025-04-13: Version 0.15.1.0 added GHC 9.12 support according to the official changelog. ### Related projects - The README names Haskell Language Server, haskell-mode, vim-autoformat, vim-stylish-haskell, stylish-haskell-vscode, Stack, Cabal, and ghc-lib-parser-adjacent packaging concerns as part of its ecosystem. ### Sources - - - - input source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
