In answer to Paul Giaccone,
The main selling point of lexertl as far as boost goes is probably speed. lexertl lexers are both fast to construct (typically under 100 milliseconds on a modern machine) and fast to tokenise input (the generated state machine uses the flex technique of equivalence classes).
I personally like the fact that you can dump the DFA as data and process it later with any language you like too.
Spirit is a parser, please don't compare apples and oranges. You cannot implement, say, Wave, with just a lexer. I suggest you don't go the "this-is-better-that-is-better" route. Spirit has its own lexer too, FYI. It's called SLex. See Slex in http://tinyurl.com/29mcn
Oh and BTW, if you want to talk about speed, matching the speed of Flex is not good enough. The thing to beat is Re2C! Hartmut and I shall see how lexertl fares soon. Wave has an adaptable front end where you can choose your own lexer. Re2C (http://re2c.org/) is one of them. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
