[antlr-interest] Code Generation Instruction Ordering / Order of Execution of Rules Actions

[Amr Muhammad]

Hello,

I was wondering if it is possible to execute actions for rules, that calls
other rules, before executing the actions for the rules, that were called.


Let's say I have the following grammar:
---------------------------------------------------------------
block_rule: BLOCK block_name
'{'
    property1_rule

    NEWLINE

    property2_rule

'}'         { // generate block of statements say s3  }  ;

property1_rule: property1= value1 { // generate block of statements say s1 }
;
property2_rule: property2= value2 { // generate block of statements say s2 }
;

block_name: ID;
property1: ID;
value1: ID;
property2: ID;
value2: ID;
---------------------------------------------------------------

I would want the actions for rule block_rule to get executed before the
actions of property1_rule or
property2_rule

I am trying to do sth like:
-----------------------------------------
block_object  block_name;
block_name.property1= value1;
block_name.property2= value2;
-----------------------------------------
but what i get is:
-----------------------------------------
block_name.property1= value1;
block_name.property2= value2;
block_object  block_name;
-----------------------------------------

Just in case it matters, what i am actually doing is using the parser
grammar to generate an AST, and then using a tree grammar to walk the tree.


Thank you for your time :)
