Code Formatter

The formatter analyzes input source text, tokenizes according to language, and applies style rules to produce a canonical, nicely formatted version. It is language-aware, supporting JavaScript, TypeScript, JSON, HTML, CSS, and related formats. Users adjust options such as indentation (spaces or tabs), indent size, maximum line length, semicolon usage, and trailing comma preferences; the tool preserves code semantics while improving readability. Outputs include a single formatted code string and a short diagnostic summary.\n\nConceptually, the tool uses a formatting engine that can parse the input into a safe internal representation, reconciles whitespace, and re-emits code with consistent tokens and layout. It avoids executing code and does not perform linting or semantic refactoring. It handles common edge cases such as mixed indentation, blank lines, and comments, and produces warnings or diagnostics in a structured form when inputs are ambiguous or unsupported.\n\nAudience and value: developers, code reviewers, teams enforcing a shared style, IDE plugin users, and CI pipelines. Differentiators: language-aware formatting, offline operation, deterministic output for same input, and extensive configuration while keeping a small footprint. Use cases include preparing pull requests, standardizing legacy code, or preparing snippets for documentation. Core features: multi-language support, customizable style presets, robust error handling, and output validation. Optional workflows: save presets, compare diffs, and export formatted results.
