Hi Akim, Thanks for everything again. One thing came into my mind concerning your question if there's any feature of bison I miss (though this may not belong to the scope of bison but another tool): a kind of reverse mode would be great:) I mean, generating the sequence of tokens from a grammar. I'm currently using nltk to test what my bison generated parser would accept: http://www.nltk.org/howto/generate.html
Or are you aware of any such c/c++ tool?
