java - Grammar inference library? -

-

what best (or any) open source libraries regular or context-free grammar inference set of examples believed generated common grammar? i'd prefer library in java, python or ruby, of course beggars can't choosers.

i did googling, couldn't find actual implementations, though did find plenty of interesting references. this library looks interesting, couldn't find available download anywhere.

edit (2011-11-14): clarity (though i'm not sure how misunderstood), question grammar inference, not grammar generation or parsing. in other words, given set of strings accord unknown grammar, find restrictive grammar satisfy.

i have not used them yet, had identical question , (after searching) found these 2 libraries, @ least:

unlike other answers question, these actual grammar inference libraries rather parser generators.
