re2c: re2c (regular expressions to C/C++ conversion tool) re2c: re2c: re2c is a tool for writing very fast and very flexible scanners. re2c: re2c focuses on generating high efficient code for regular expression re2c: matching. As a result this allows a much broader range of use than any re2c: traditional lexer offers. And last but not least, re2c generates re2c: warning free code that is equal to hand written code in terms of size, re2c: speed and quality. re2c: re2c: Homepage: http://re2c.org re2c:
