digitalmars.D.announce - dparser with *, ? and + operators
- BCS (13/13) Feb 04 2007 I have committed a new version...
I have committed a new version of the dpaser template based parser generator. It now supports the *, ? and + operators. I haven't tested it much but it seems to work if you are carefully how you wright your grammars. http://www.dsource.org/projects/scrapple/browser/trunk/dparser/dparse.d please try to break it (and tell me when you do) I know this grammer fails for some cases (but I don't /think/ LALR1's will get it either) One : Two? a b; Two : Three? a; Three : a; One -> Two a b -> a a b fails p.s. still no plans for "( exp )" forms, but thats what I said about *, ? and + <g>
