Online Groovy Formatter

The Online Groovy Formatter is a language-aware tool that reformats Groovy source code to improve consistency and readability across teams. It focuses on whitespace, indentation, and line-wrapping rules rather than code fixes. Users include developers, code reviewers, and CI systems seeking standardized formatting before reviews. It accepts a Groovy source string and returns a formatted version that preserves comments and string literals while aligning blocks and calls.
Conceptually, the formatter performs tokenization to identify blocks, closures, and chained method calls, then applies indentation and wrapping decisions. It defaults to two-space indentation but allows four spaces or tabs. A maximum line length option can wrap long expressions. It preserves comments, multiline strings, and GStrings, and avoids changing semantic elements or identifiers. Outputs are suitable for diff reviews and consistent code style.
Who benefits: teams enforcing a shared Groovy style, code reviewers seeking lower review times, and automated pipelines that enforce formatting on commit or pull requests. Core features include: language-aware reflow, configurable indent and line-length, preservation of blank lines when desired, and exportable formatted_code. Optional advanced features cover multiple style profiles, project defaults, and batch formatting via API.
Use cases include bulk formatting of repository files, integration into pre-commit hooks, and CI-driven formatting to maintain a consistent codebase across Groovy projects.
