re2c

re2c is an open-source lexer generator that compiles regular expressions into high-performance, direct-coded scanners for multiple programming languages including C, C++, Go, Rust, and Python. It utilizes lookahead Tagged Deterministic Finite Automata (TDFA) to generate fast code with minimal overhead, supporting submatch extraction without the need for table-driven structures. The tool is designed for flexibility, allowing embedded lexers within source code and optimized for debugging and execution speed.
