Hi, I'm newer on using Sablecc and I have a simple question in the rules expressed in the productions of the specification-file of sablecc... When I have, for example: statement = {if} if condition [nl1]:new_line ... What's the meaning of the [nl1]:new_line, i.e, the construction [__]:____??? I have studied Etienne's thesis but I think I missed some details... Thanks in advance, Joseane.
