About This Tool

Code Formatter Carbon provides language-aware reformatting of code snippets to a consistent style suitable for docs and reviews. It uses the language's formatting rules and a set of configurable options to produce readable, maintainable code blocks.
Conceptually, the tool parses input code with language-specific parsers and emits a reformatted version according to the chosen style: indentation, line length, and whitespace rules. When a parser is not available, it falls back to token-based reformatting that preserves semantics while improving layout.
Audiences benefit include developers preparing API samples, technical writers editing guides, and educators crafting demonstrations. Unique value lies in cross-language consistency, idempotent results, and seamless integration with documentation pipelines. Core features include per-language presets, custom user configs, option to preserve comments, trailing newline handling, and diagnostics reporting.
Outputs include formatted_code and a concise diagnostic list to guide further refinement. This tool is designed for teams enforcing coding standards across repositories while maintaining high-quality, readable documentation.

Frequently Asked Questions

Find Quick Answers

What languages are supported?

The tool supports major programming languages with dedicated AST-based formatters where available (e.g., JavaScript/TypeScript, Python, Java, Go, C/C++). If a parser is unavailable, a robust token-based formatter is used as fallback.

Does it preserve comments?

Yes, to the extent the language parser supports comment preservation. Inline and block comments near code blocks are retained when possible; some edge cases may be adjusted by the formatter rules.

Can I customize style rules?

Yes. Users can configure indent_style, indent_size, max_line_length, and wrap behavior. Per-language presets and project-level config files can be used to enforce consistency.

Is minified code reformatted safely?

Minified or dense code can be reformatted, but parsing may be challenged. The tool provides diagnostics to indicate potential parsing issues and may apply conservative formatting to avoid semantic changes.
