GnuWin32: Bison-2.4.1 Download

GnuWin32: Bison-2.4.1 is a native Windows port of GNU Bison, a general-purpose parser generator. It reads a grammar written in Yacc-compatible syntax and produces efficient C source code for an LALR(1) or GLR parser. This port brings Unix-style parser generation to Windows without requiring a POSIX layer, making it suitable for building compilers, interpreters, domain-specific languages, and file format parsers on Microsoft platforms.

Key features:

Yacc compatibility with modern Bison extensions
Reentrant and pure parsers, location tracking, and detailed conflict reports
C output that compiles with common Windows toolchains (e.g., MinGW/GCC, MSVC)
Optional debugging traces and verbose .output files for grammar analysis
Works well alongside lexical analyzers such as Flex (also available from GnuWin32)

Package contents typically include the bison executable, parser skeletons, documentation, and examples. A C compiler is required to build the generated parser.

License: GNU GPL with the standard Bison exception that permits using the generated parser code in proprietary or open-source programs.
