Which (of course) means that that is exactly what happens ;) The ones that match are ababbb (a (ba+bb) b) => r4 r1(r3(r5 r4) r2(r5 r5)) r5 abbbab (a (bb+ba) b) => r4 r1(r2(r5 r5) r3(r5 r4)) r5 With the ^1, in the “bb” cases the first “b” eats all three “b”s: ababbb fails the r5 at the end abbbab fails the first r2 already (since the second r5 therein never happens) Best wishes, Taco ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___________________________________________________________________________________
