C++ Code Formatter

The C++ Code Formatter analyzes input source and applies a deterministic reprint that enforces a chosen style. It operates on a token/AST level to preserve comments and preprocessor directives while reformatting whitespace, line breaks, and brace placement. Conceptually, it separates concerns: parsing and semantic structure are kept intact, while presentation is standardized. Beneficiaries include developers seeking faster code reviews, team leads enforcing conventions, and CI systems that require consistent diffs. Unique value lies in support for multiple established presets (e.g., Google, LLVM, GNU), plus customizable options for indentation, max line length, and macro handling. Core features include: 1) AST-aware reprinting that respects C++ syntax; 2) comment and macro preservation; 3) configurable indentation (spaces or tabs) and width; 4) brace and spacing rules that align with selected style; 5) option to apply or ignore line wrapping for long expressions; 6) diff-friendly outputs to ease reviews. Typical use cases include formatting a single file before a pull request, reformatting an entire codebase in a CI pipeline, or aligning new contributors with project conventions.
