A simple question...




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.
