[antlr-interest] WG: Question to the tree grammer

I want to switch from yacc. So I've looked on Videos from Scott
Stanchfield <http://vimeo.com/user566590> , especially on Part9 about a
tree grammar.

I've found a problem with an unary operator. The Interpreter in Eclipse
works fine, but the grammar tree not.

It simply can't accept things like this:

 

-5 - - + - 4

 

I've attached also my files. Is there a way, how can I ask somebody
else, than me? I assume, it is something with left/right association, is
it?

 

Thank you for hints

 

Richard
