23:05 VsyachePuz What I don't understood about scannerless parsers: Is it impossible to automatically separate full grammar into nonregular and regular parts? And then generate scanner automatically (because regexp parsers are for speed only)
23:28 pczarn VsyachePuz: it is possible, but a scannerless grammar is likely to have ambiguities which make regex scanning pointless.
23:31 pczarn I think it would be great to separate just the lexer into nonregular and regular parts.
23:40 pczarn Actually, regex scanning could work despite ambiguities.
23:50 pczarn VsyachePuz: to finally answer your question: in a typical grammar, the separation of lexing and parsing is important to weed out ambiguities by choosing longest possible tokens.
