ISO C++23 / C++20 Features

Full support for Concepts (template <typename T> concept Numeric), Fold expressions ((args + ...)), Coroutines, and operator<=>.

Security Safeguards

Treats C++ code strictly as text data for formatting. NEVER compiles, links, or executes CMake/GCC binaries on the host machine.

Stroustrup & Allman Styles

Support for Stroustrup (Same Line {) and Allman (New Line \n{) brace styles, constructor initializer lists, and template parameters.

Raw Strings & Doxygen

Raw strings (R"(raw)"), attributes ([[nodiscard]]), and Doxygen comments (///) are preserved verbatim without altering contents.
