## プロジェクトの歴史と使われ方

erlfmt is WhatsApp's opinionated Erlang code formatter, packaged as a CLI and rebar3 workflow for teams that want consistent Erlang formatting.

### プロジェクトの歴史

The README describes erlfmt as an automated formatter that lets teams focus on code behavior rather than formatting debates. The project reached version 1.0.0 on June 29, 2021 and states that it is feature complete, with only backwards-compatible changes and bug fixes considered without serious review.

### 採用の歴史

erlfmt's main adoption path is as a rebar3 project plugin, adding a rebar3 fmt task and CI-friendly --check mode. The README also documents standalone escript use and editor integrations.

### 使われ方

Users add erlfmt to project_plugins in rebar.config, run rebar3 fmt to format a project, or run the escript directly against Erlang source globs. Later releases kept pace with OTP language changes, including OTP 27 sigils and triple-quoted strings and OTP 28 comprehension features.

### パッケージ好きにとっての重要性

For package managers, erlfmt is valuable because it is a deterministic formatter with a deliberate stability promise after 1.0. That makes it suitable for CI checks and repository-wide formatting without a constantly shifting style baseline.

### タイムライン

- 2021-06-29: erlfmt 1.0.0 released.
- 2024-09-03: erlfmt 1.5.0 added OTP 27 feature support.
- 2025-06-13: erlfmt 1.7.0 added OTP 28 feature support.
- 2026-02-23: erlfmt 1.8.0 added more formatter enhancements and fixes.

### Related projects
