[antlr-interest] writing an interpreter

[Maciej Zawadziński]

Hi!

I am gonna write an interpreter of simple language. I am thinking of
implementing it as a treewalker, but I encountered some problems with
loops. How can I force ANTLR treewalker not to parse some nodes of
tree? (e.g. "body" of the if/while loop if the condition is not
satisfied?)

regards,
Maciek
