IMPORTANT: This project is no longer maintained by Pinterest. As a result the Maven coordinates of the project have changed from com.pinterest.ktlint to io.github.ktlint. Read more in the documentation.

Note: Earlier alpha versions are not available as GitHub, nor as Maven Central download due to problems in fixing the release pipeline.

🆕 Features

  • Execute all rules on same AST Node before proceeding to next AST Node (possibly breaking change) - #3252, by @paul-dingemans
    Due to changing the order in which rules are executed, this is a potentially breaking change when rules are not well written. Normal rules only manipulate the AST for nodes that have not yet been visited. In case a rule for a given AST Node decides to manipulate an AST Node that already has been visited before, this might result in a failure.
