WinFlexBison is a Windows port of Flex (the fast lexical analyser) and GNU Bison (parser generator). Both win_flex and win_bison are based on upstream sources but depend on system libraries only.
NOTE:
- 2.4.x versions include GNU Bison version 2.7
- 2.5.x versions include GNU Bison version 3.x.x
Bison 3.x (master) and, for compatibility reasons, Bison 2.7 (bison2.7)
https://github.com/lexxmark/winflexbison/releases provides stable versions. To test non-released development versions see the artifacts provided by CI under "Build status".
The release page includes the full Changelog but you may also see the changelog.md file.
- Visual Studio 2017 or newer
- optional: CMake (when building with CMake)
You may use win_flex and win_bison directly on the command line or use them via CustomBuildRules in VisualStudio.
