My interest in regular expressions is limited to maintaining CLISP regexp & pcre modules: <http://clisp.cons.org/impnotes/modules.html#pcre> <http://clisp.cons.org/impnotes/modules.html#regexp> this specific issue was motivated by my attempt to adopt a regexp testsuite <http://cvs.sourceforge.net/viewcvs.py/*checkout*/clisp/clisp/modules/regexp/test.tst> (comments welcome - not here but on <http://lists.sourceforge.net/lists/listinfo/clisp-list>) Could you (or anyone else) explain to me the rationale behind BREs supporting back-refs and EREs not supporting them? This is very counterintuitive. I don't think this is directly relevant to cygwin, so private e-mail is welcome. -- Sam Steingold (http://www.podval.org/~sds) running w2k <http://www.camera.org> <http://www.iris.org.il> <http://www.memri.org/> <http://www.mideasttruth.com/> <http://www.honestreporting.com> If you think big enough, you'll never have to do it. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
