About This Tool

The tool accepts a code block and a target language, then applies language-specific formatting rules to normalize indentation, line length, and whitespace. Conceptually it tokenizes or parses the code lightly to respect syntax while reflowing lines so that samples appear consistently. Benefits include faster review cycles, improved documentation clarity, and easier reuse of snippets across repos. Core features include language support, adjustable line length, indentation presets, and batch formatting capabilities that can process multiple blocks in a single run. It preserves comments and strings, avoids altering semantics, and can optionally wrap long lines to maintain readability in narrow docs panes. Use cases include formatting Python examples for a README, JavaScript snippets for API docs, or C++ blocks in a user guide; teams can standardize style across a code base, improving contributor onboarding and collaboration.

Frequently Asked Questions

Find Quick Answers

Which languages are supported?

The formatter supports common programming languages such as Python, JavaScript, Java, C++, and C#. It uses per-language rules to preserve syntax while applying consistent indentation and line wrapping.

Can I customize the formatting style?

Yes. Users can choose indentation width (2 or 4 spaces), preferred line length, and wrap behavior. Presets can be saved for future sessions to maintain consistency across projects.

Does formatting alter code semantics?

No. The formatter only adjusts whitespace and structure. It preserves identifiers, literals, comments, and the overall syntax without altering runtime behavior.

Can I format multiple blocks at once?

Yes. The tool supports batch processing, allowing several code blocks to be formatted in a single operation for efficiency when preparing large documentation sets.
