Show HN: Yantra – an LALR(1) parser generator for C++
TL;DR
Yantra is a C++ LALR(1) parser generator that enables efficient bottom-up parsing and lexer-driven processing. Its features include a multi-mode lexer and an optional single-file output for easy integration.
✦ Why It Matters
Explore Yantra today to streamline your C++ parsing projects with advanced features.
Key Takeaways
- Clone the Yantra repository and build using CMake.
- Define your grammar in a .y file for parser generation.
- Compile the generated parser with a C++23 compiler.
- Utilize the lexer-driven parser for real-time input processing.
How It Works
Yantra employs a lexer-driven approach, meaning it reads input character by character and feeds completed tokens to the parser. This allows for immediate processing of input, which is particularly useful in scenarios like network sockets.
The parser first constructs an AST from the entire input before executing semantic actions, enabling parent rules to execute before their child rules.
