Well, now that I succeeded to get passed the problem... I don't know if there is a bug or not.
Looking at LL parser theory, it may not be that surprising -- combinatory explosions when building an LL parser who needs more left-factorizations. Besides I'm working on a quite big grammar and that probably plays a role here. ANTLR probably handles such rules quite well on not-so big grammars. Finally, all this mess occured on a non-working grammar. So I have the feeling that it's not that big an issue for the user. Well, one entry in some FAQ for people migrating LR parsers to ANTLR would have done the trick, I'd say. If I have just been reassured that fixing the left-factorization would have solved the problem, I'd simply worked on left-factorizing my grammar and stopped worrying. In absence of any advice on the matter I kind of panicked instead. :-) JP Le 06/01/2010 18:08, Jim Idle a écrit : > OK - just try it without any options then and if the behavior changes add > back each option in turn and see which one affects it.
