Its defining design choice is a single formatting style with no user style configuration, built on GHC's parser to avoid the parsing gaps that affected older Haskell formatters. ### 项目历史 The tweag/ormolu repository was created on 2018-11-25. Tweag announced Ormolu publicly in May 2019, describing a formatter that would use GHC's own parser, aim for minimal diffs, be robust on large projects, and avoid configurable formatting styles. Tweag announced the first Ormolu release on 2019-10-11. That post said the tool had been run on large real-world projects, legacy codebases, and popular packages, and that the first release formatted Haskell constructs, handled language extensions, placed comments, normalized pragmas and imports, and ran fast enough for large codebases. The DESIGN.md file records the early analysis of Brittany, Hindent, Stylish Haskell, and haskell-formatter. The design borrowed goals such as preserving meaning when CPP is not used, preserving comments, idempotence, and linear space and time behavior, while avoiding parser bugs from haskell-src-exts. ### 采用历史 Ormolu became one of the standard Haskell formatter choices because it paired opinionated formatting with ecosystem integration. The README documents Hackage and Stackage availability, release binaries for Linux, macOS, and Windows, Nix builds, editor integrations for Emacs, VS Code, and Vim, built-in Haskell Language Server support, and a recommended GitHub Action. Tweag's 2021 internship writing says the use of the GHC parser and testing gave Ormolu a reputation as a dependable tool, with more industrial users choosing it as their Haskell formatter. Later work focused on GHC parser upgrades, Ormolu Live, Cabal-file awareness, CPP handling, and magic comments for disabling formatting regions. ### 使用方式 Developers run ormolu on files to print formatted output, use --mode inplace to rewrite files, and use --mode check in CI to fail when code is not formatted. Recursive use is usually via find or git ls-files, while editor and HLS integrations make it part of save-time formatting. Ormolu reads Cabal files and .ormolu files for technical formatting inputs such as default extensions, package dependencies, fixities, and re-exports, while keeping the main visual style non-configurable. Magic comments let users disable and re-enable formatting for regions that require manual layout. ### 为什么软件包爱好者会关心 Ormolu is package-nerd-significant because it captures a language-community shift toward formatter standardization: the package is small, but its value comes from reducing code-review churn, CI disagreement, and style bikeshedding in Haskell projects. Its distribution footprint is unusually broad for a language formatter: Hackage library and executable, Stackage inclusion, binary releases, Nix support, Homebrew/Linux packages, Haskell Language Server integration, editor plugins, and GitHub Actions. ### 时间线 - 2018-11-25: tweag/ormolu repository created on GitHub. - 2019-05-27: Tweag announced Ormolu before ZuriHac 2019. - 2019-10-11: Tweag announced the first Ormolu release. - 2021-04: Tweag described follow-up work around parser upgrades, bugs, and industrial use. - 2021-10: Tweag described internship work on Ormolu Live, Cabal-file support, CPP handling, and magic comments. ### Related projects - Related Haskell formatting tools include Brittany, Hindent, Stylish Haskell, haskell-formatter, and Fourmolu.
