Fancy creating your own programming language? Or perhaps you want to write a compiler or interpreter for an existing language? Check out the latest addition to
the Free Compiler Construction Tools: Lexers, Parser Generators, Optimizers
page. The program, re2c, creates a fast lexical scanner for regular expression matching. It can take its input from anything you want, even a buffer that
you create on-the-fly, since unlike most lexical analyzers, it is not tied to any input model.
