Hi all,

   Im facing this problem of converting parser grammar to tree grammar.
I have some rules which incrementally build ASTs  like the following
example:

postfixExpression : (primary->primary)
( '(' args=expressionList ')'
-> ^(CALL $postfixExpression $args)
| '[' ie=expression ']'
-> ^(INDEX $postfixExpression $ie)
| '.' p=primary
-> ^(FIELDACCESS $postfixExpression $p)
)*
;

Best Regards,
Jevitha
