I replaced a handwritten lexer of a proprietary PDF library with a re2c generated lexer. Besides fixing a bunch of dormant bugs, the resulting lexer was much faster.
Also the state of c++ std regex implementations is pretty sad (at least it was the last time I checked) and if you just need to match with a few compile-time-known regexes, re2c is there for you to solve the problems. |
