Lex and Yacc
This is the seminal text on using these great tools Lex and Yacc to help build compilers. We use these tools in a few of our products such as PFCLObfuscate that is used to protect PL/SQL and as suc we need to parse PL/SQL. We also have a parser in PFCLCode which is used to check PL/SQL for security issues such as SQL Injection. We also have two more parsers / intepreters in PFCLScan but these use hand lexers and parsers written in C.
Great Book!!
