    GNU bison, commonly known as Bison, is a parser generator that is part of the GNU Project. Bison reads a specification of a context-free language, warns about any parsing ambiguities, and generates a parser (either in C, C++, or Java) which reads sequences of tokens and decides whether the …

    I bought Flex & Bison from O’Reilly but I’m having some trouble implementing a parser (breaking things down into tokens was no big deal). Suppose I have a huge binary string and what I need to…
