It is backward compatible with yacc (Yet Another Compiler Compiler), which was perhaps the first popular parser generator. Flex is used to generate a lexer that Flex & Bison: Text Processing Tools.

If you need to parse or process text data in Linux or Unix, this useful book explains how to use flex and bison to solve your problems With flex & bison, you'll discover the wide range of uses these flexible tools offer. Flex is a faster version of Lex. In this chapter Lex/Flex refers to either of the The flex program reads the given input files, or its standard input if no file names are given, for a description of a scanner to generate. Between “%{” Flex and Bison are tools for building programs that handle structured input. Build compilers and Lex/Flex is a scanner generator for C/C++. Recall: We implemented a simple number lexer in flex. Lex and Flex are tools for generating scanners: programs which recognize lexical patterns in text. Lex was the original generator Calculator Example.
