re2c is a preprocessor that generates C-based recognizers from regular expressions. The input to re2c consists of C/C++ source interleaved with comments of the form /*!re2c ... */ which contain scanner specifications. In the output these comments are replaced with code that, when executed, will find the next input token and then execute some user-supplied token-specific code. re2c generates parsers which are not table-based, and can be twice as fast as flex.
