Use code binds a function to an action by name at run-time. The action function is accepts the data on the parser's stack matching the right-hand side of the production and returns the data that will be stored in the stack, in place of the right-hand side elements, with the left-ha...
A modern AST grammar lexer/parser generator written in C. Neoast can take arbitrary lexing and grammar rules and generate a scanner and parsing table. Unlike Bison/Flex, neoast does not generate the scanner and parsing runtime for each input, it uses the same algorithm and links a static ...

The C/C++ parser module generated by AnaGram from your description can be compiled on virtually any platform. By incorporating the parser into a DLL, you can even use it in Delphi or Visual Basic programs. About AnaGram 2.01: AnaGram 2.01runs on Win32 platforms. AnaGram generates ANSI compatib...
See "Enabling Relocatability" in the documentation. Internationalization Bison supports two catalogs: one for Bison itself (i.e., for the maintainer-side parser generation), and one for the generated parsers (i.e., for the user-side parser execution). The requirements between both differ: biso...
