About:
BNFC is a compiler-compiler tool that generates an abstract syntax tree and a lexer/parser from an LBNF grammar file. It supports multiple target languages including Haskell, Java, C, and C++, significantly simplifying the development of language processors. Its main value is reducing the boilerplate code needed to build language frontends.
Key Features:
  • Generates lexers and parsers from LBNF grammar
  • Supports multiple target languages (Haskell, Java, C, C++)
  • Automatic construction of abstract syntax trees
  • Built-in support for layout and comments
Use Cases:
  • Creating domain-specific languages (DSLs)
  • Building compilers for educational or research languages
  • Implementing configuration file parsers
Alternatives:
  • Happy – Haskell parser generator, requires manual lexer integration
  • ANTLR – More complex, Java-based, supports more advanced grammar features
