It's a _large_ topic but one that does admit very precise analysis. for me, to know is not as important as how i come to know (that is, the learning process). one of these days i'll finish writing the program that will automatically produce the "illustrated guide to regular expression engine internals" (as a specialization of the more general illustrated guide to digital logic specification and evaluation). text pattern languages that require backtracking (but don't obviously lack linear alternatives of comperable expressiveness (but are dirt simple to implement)) and what do we do about regular expression engines that think they are only about contiguous text? if i understand you correctly, this illustrated guide will have to admit several fundamental regexp engines; there is no unifying architecture possible. (shrug.) that's fine, too. so it goes. thi [cc trimmed] _______________________________________________ Guile-user mailing list Guile-user@gnu.org http://mail.gnu.org/mailman/listinfo/guile-user
