history

Project history and usage

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.

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.
