Re issue97, I'm pretty confident that you can't express accurately the sort of symbols that the poster is talking with a regular language. Even if we leave out the huge hariness of things like Lisp (where you can redefine the reader functions to behave completely differently) and talked about something fairly static like XML, I think you need a context-free language. And yes, support for XSLT/XQUERY mutation as a fundamental patch primitive (in addition to the existing line-oriented patch primitives) would be amazingly cool. But I don't want to bang my head on it right now. _______________________________________________ darcs-users mailing list [email protected] http://lists.osuosl.org/mailman/listinfo/darcs-users
