About This Tool

This tool formats Java source code by applying a deterministic style profile. It preserves comments and string literals while adjusting whitespace, indentation, and brace placement to improve readability. It supports batch processing and per-project profiles to align with existing conventions.
Conceptually, the formatter tokenizes the source, applies rules per the selected profile, and reconstructs the code. It ensures idempotence: formatting the already formatted code yields no further changes.
Beneficiaries include developers seeking consistency, code reviewers, and teams adopting a shared style. It integrates with repositories and can run in automated pipelines to maintain uniform formatting across commits.
Core features include indentation normalization, line wrapping, brace style enforcement, and diff reporting. Use cases include pre-commit formatting, CI integration, and onboarding new engineers.

Frequently Asked Questions

Find Quick Answers

Which languages are supported?

Primarily Java. The tool is designed for Java source files and follows Java formatting conventions. Other languages may be supported in future releases; current behavior for non-Java inputs is to reject or request language specification.

Can I customize formatting rules?

Yes. You can select built-in rule presets (such as standard Java styles) or provide a custom profile that defines indentation, line length, and brace style. Profiles can be reused across projects.

Is there an API or CLI?

The formatter exposes a REST API and a CLI for automation. It supports single-file and batch formatting, diff generation, and export of results. Authentication and rate limits apply for API usage.
