re2c

tool for generating fast C-based recognizers

re2c is a great tool for writing fast and flexible lexers. Unlike other such tools, re2c concentrates solely on generating efficient code for matching regular expressions. Not only does this singleness make re2c more suitable for a wider variety of applications, it allows one to generate scanners which approach hand-crafted ones in terms of size and speed.
