[antlr-interest] how to best break apart multiple assignments

[Indhu Bharathi]

How about something like this?

r    :    (ID EQ)+ INTLIT SEMICOLON -> ^(ASSIGN ID INTLIT)+
    ;

So, for your example, this will create two subtrees with ASSIGN as root. 
The tree generated will be ^(nil ^(ASSIGN Odd 0) ^(ASSIGN Even 0))

And then you can write string template in the tree walker and emit out 
as you need.
