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

Yantra is an LALR(1) parser generator for C++ that features an integrated lexer, built-in AST builder and walker, and support for Unicode/UTF8 input with no external dependencies beyond the C++ standard library. The tool can generate parsers in either a single self-contained file or separate modular files, and supports both file-based and stream-based input processing. Users can define grammars in a simple syntax and compile the generated parser with any C++23-compatible compiler.
