## プロジェクトの歴史と使われ方

ktlint is an anti-bikeshedding Kotlin linter with a built-in formatter. Its docs describe it as a Kotlin linter in the spirit of JavaScript Standard Style and gofmt: low setup, conventional defaults, and automatic formatting when possible.

### プロジェクトの歴史

The documentation copyright trail records Stanley Shyiko's original 2016-2019 authorship and Pinterest's 2019 stewardship. The repository later moved from the pinterest namespace to the ktlint organization on GitHub, while the Homebrew package still records the historical pinterest/ktlint repository URL.

### 採用の歴史

ktlint gained adoption by combining a CLI jar, Maven/Gradle integrations, reporters, custom rule sets, .editorconfig support, and package-manager distribution. Its docs emphasize no-configuration defaults, Kotlin coding conventions, Android Kotlin Style Guide alignment, and extensibility for organizations that need custom checks.

### 使われ方

Users run ktlint to scan .kt and .kts files, optionally with --format or -F to autocorrect violations. Teams commonly add it to build pipelines, pre-commit hooks, editor workflows, or Gradle/Maven tasks, with .editorconfig and baseline files used when defaults need project-level adjustment.

### パッケージ好きにとっての重要性

ktlint is significant because it became the Kotlin ecosystem's canonical packaged linter/formatter pair: one executable jar, common default rules, multiple reporters, custom rulesets, and enough integration points to make style enforcement portable across editors, CI, and package managers.

### タイムライン

- 2016: The docs copyright trail begins Stanley Shyiko's authorship period.
- 2019: Pinterest stewardship appears in the docs copyright trail.
- 2024-12-04: Tag 1.5.0 was published in the GitHub tag history.
- 2025-11-14: Release 1.8.0 was published on GitHub.

### Related projects
