Online Code Formatter

The tool formats code using language-aware rules to ensure consistent style across a range of programming languages. It processes an input code_text and applies language-specific indentation, line breaks, and spacing to produce a clean, readable form. Conceptually, it relies on a parser or heuristic for each supported language to build a representation of the code and then reprint it with standardized formatting. This reduces cognitive load during reviews and collaboration, and helps teams enforce style guidelines. It benefits developers who work across languages, educators preparing samples, and students learning proper formatting. Core features include deterministic formatting, configurable indentation, wrap length, and the option to auto-detect language. The tool distinguishes between code and non-code regions (comments, strings) to preserve semantics while adjusting presentation. It can generate diagnostics when a snippet cannot be formatted with full language rules, guiding follow-up edits. The value lies in improved readability, faster reviews, and consistent presentation of code across repositories and projects. Use cases include preparing code samples for documentation, standardizing code blocks in tutorials, and enabling automated pre-commit formatting in CI pipelines. The formatter aims for idempotence: repeatedly formatting a snippet should yield the same result. Advanced users can supply per-language presets to align with team style guides.
