Projects / re2c


re2c is a tool for writing fast and flexible lexers. Unlike other such tools, it concentrates solely on generating efficient code for matching regular expressions. This make it suitable for a wide variety of applications. The generated scanners approach hand-crafted ones in terms of size and speed.

        Release Notes: This is hopefully the last development release of the 0.13 cycle, and should lead to a stable 0.14 release.
