## プロジェクトの歴史と使われ方

ktfmt is Meta's Kotlin formatter, built to pretty-print Kotlin code deterministically and with minimal style choice. The project describes itself as based on google-java-format and intentionally non-customizable to promote consistency.

### プロジェクトの歴史

The repository README describes ktfmt as a formatter that reformats Kotlin source code and compares its output with ktlint and IntelliJ formatting. Its website emphasizes that the same input always receives the same output, regardless of initial layout, so developers can avoid style debates.

### 採用の歴史

ktfmt is consumed both as a command-line jar and through integrations: a JetBrains IDE plugin, Gradle and Maven examples, Spotless integration, Maven Central artifacts, and Homebrew packaging. That puts it in the same culture as gofmt and google-java-format, where a formatter's value is partly social: teams agree to stop arguing about layout.

### 使われ方

Users run ktfmt from the command line, through build tooling, through Spotless, or through the IntelliJ and Android Studio plugin. The README documents editorconfig use for approximating ktfmt behavior in IDE editing and command-line options for whole-file or partial formatting.

### パッケージ好きにとっての重要性

ktfmt matters to package people because it packages style as an executable policy. It is a Kotlin example of formatter distribution via Maven Central, IDE plugins, build plugins, jars, and Homebrew, with very little configuration surface by design.

### タイムライン
