This is an interesting and crucial assertion. If the regex syntaxes do not have a useful overlap, only libraries that allow regexs to "pass through" from the app to the platform (creating no new regex objects of their own) will be portable, at which point wrapping the pattern in a clojure-something becomes rather less useful (except I suppose for the original IFn point). But is it true? The amount of overlap between, for example, JVM and JavaScript is quite substantial, both having borrowed features and syntax quite heavily from perl. http://www.regular-expressions.info/refflavors.html I think that a s long as we're not trying to support ancient engines (such as sed, awk, emacs...) the subset that overlaps would be quite useful. --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
