[antlr-interest] How to get rid of useless nodes in AST?

[Sam Harwell]

Hi Jarrod,

I added a comment to the answer you posted at StackOverflow. The method you call the "alternate" method is the only proper solution posted on the entire page. When the AST operators (used for the "alternate" method) are able to produce the tree shape you want, then using rewrites shouldn't even cross your mind as an option. Find a way to make it work for you, perhaps by altering the display code to produce the labels you want instead of showing the operator text itself.
