history
Project history and usage
elm-format is the standard formatter used by many Elm projects to normalize source layout in the style of gofmt. Its official README presents it as a formatter for Elm code based on the Elm style guide, with the practical goal of removing formatting debates from code review.
Project history
The project grew around Elm's transition from an experimental FRP language into a more conventional frontend language with project files and a stable command-line toolchain. Its releases track Elm syntax and project-file eras: the README still documents both Elm 0.18's elm-package.json and Elm 0.19's elm.json, and the release history includes Elm 0.19 alpha and 0.8.x releases.
Adoption history
Adoption was driven less by a standalone ecosystem and more by editor and workflow integration. The README documents format-on-save support across Atom, Vim, Emacs, Visual Studio Code, Sublime Text, JetBrains IDEs, and other tooling, showing that elm-format became part of the everyday editor setup for Elm programmers.
How it is used
The typical usage is direct and project-local: run elm-format on a file or directory, optionally with --yes to overwrite, from a directory containing elm.json or elm-package.json. The tool is also commonly invoked by editor plugins on save and by formatter integrations such as Prettier plugins.
Why package nerds care
For package maintainers, elm-format matters because it makes source diffs more mechanical and keeps package examples, source files, and contributions visually consistent across the Elm ecosystem. It is a small CLI whose importance comes from convention: once a formatter is expected, packages that use it are easier to review and compare.
Timeline
- 2017: 0.7.0-exp release appears in the GitHub release history.
- 2018: 0.8.0 release aligns the formatter with the Elm 0.19 transition.
- 2023: 0.8.7 release continues maintenance for the Elm 0.19-era formatter.
- 2025: 0.8.8 release is published.
Related projects
- elm-format follows the same convention-over-style-debate niche as gofmt, but for Elm source files. It is also related to Elm editor plugins and Prettier's Elm integration, which use it as part of save-time or pipeline formatting.
