(you know... 'da parser)


DParser is an simple but powerful tool for parsing.  You can specify the form of the text to be parsed using a combination of regular expressions and grammar productions.  Because of the parsing technique (technically a scannerless GLR parser based on the Tomita algorithm) there are no restrictions.   The grammar can be ambiguous, right or left recursive, have any number of null productions, and because there is no separate tokenizer, can include whitespace in terminals and have terminals which are prefixes of other terminals.   DParser handles not just well formed computer languages and data files, but just about any wacky situation that occurs in the real world.
