lex & yacc

This book shows you how to use two Unix utilities, lex and yacc, in program development. These tools help programmers build compilers and interpreters, but they also have a wider range of applications. You'll find tutorial sections for novice users, reference sections for advanced users, and a detailed index. Each utility is explained in a chapter that covers basic usage and simple, stand-alone applications. You'll learn how to implement a full SQL grammar, with full sample code. Major MS-DOS and Unix versions of lex and yacc are explored in depth. Also covers Bison and Flex.
