Show HN: Yantra – an LALR(1) parser generator for C++

Yantra is a C++ parser generator that builds the whole Abstract Syntax Tree (AST) first and then walks it top-down, allowing for more flexibility in semantic actions. It is designed to be used as a single tool to generate both the lexer, parser, and AST walker. Key features include integrated lexer with mode support, optional single-file output mode, and C++23 support. The project is still in its early stages (version 0.5.1) and is maintained by a single person. It is licensed under MIT and has a documentation page listing known gaps and limitations. The project is open to feedback and questions.
