Flex
Claimed by GNU Analyzed about 3 years ago
Flex a tool for generating text scanners in C. The input file read by Flex specifies a set of rules (code to be executed when a pattern is found) which describe the scanner to be generated. The output of Flex is a C source file which can be compiled and linked with your sources, giving to your

Ragel
Analyzed about 3 years ago
Ragel compiles finite state machines from regular languages into executable C, C++, Objective-C, D, Java or Ruby code. Ragel state machines can not only recognize byte sequences as regular expression machines do, but can also execute code at arbitrary points in the recognition of a regular language.
