Sorry, I did not see that list thing, but I was trying to get you on the right track.
First, don't use literals Put the tokens in subrules Change the token type in subrule (I usually just set the type field in the token, but that is a bit of a cheat) I don't have time to test every code snippet that I post here x: t1+=void (t2+=star)* -> ^(LIST $t1 $t2*) ; void: t=VOID -> TYPE[$t]; stat: t=STAR -> TYPE[$t]; VOID: 'void'; STAR: '*'; Jim > -----Original Message----- > From: antlr-interest-boun...@antlr.org [mailto:antlr-interest- > boun...@antlr.org] On Behalf Of Christian > Sent: Wednesday, October 19, 2011 2:24 PM > To: antlr-interest@antlr.org > Subject: Re: [antlr-interest] Rewriting a list of tokens to a list of > custom tokens > > No, your solution still generates invalid java code for me.
