An extended library for C programming providing regex, parsing & more.
The Phorward Foundation Toolkit (libphorward) provides a powerful, extensional set of useful functions for C programmers. It focuses on compiler development-related tasks, but can also be used for general purpose development tasks using the C programming language. It comes with many useful extensions for universal linked lists, hash-tables, dynamic stacks and arrays, extended string management functions and some platform-independent, system-specific helper functions. Based on top of these general purpose functions, the Phorward Foundation Toolkit provides more specializing tools for regular expression handling and parser implementation, focusing on both LL and LR/LALR grammars and parsers.
