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. ### Project history 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. ### Adoption history 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. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 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 - Related projects include Kotlin coding conventions, Android Kotlin Style Guide, gofmt, JavaScript Standard Style, ktfmt, Gradle, Maven, and .editorconfig. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
