Separation of grammar and semantic actions

• terminal and noneTerminal names must be unique! add validation

• nested rules for DSL methods.

• custom names for nested rules.

  • $.OPTION("items", function() {
               $.SUBRULE($.value);
               $.MANY("values", function() {
                   // allow multiple nesting levels???
                   $.OPTION("prefix", function() {
                     $.CONSUME(Dollar);
                   }) 
                   $.CONSUME(Comma);
                   $.SUBRULE2($.value);
               });
           });

  • performance impact/mitigation for multiple args support due to the names arg being first

  • unique name per OR alternative

  • validations

    • duplicate custom names?

• activating semantics directly on nested rules using package namespace "items$values"

• Nested rules:

• Full name includes top REAL rule name.
• Full name is always two levels deep.
• name must not conflict with other terminal/NonTerminal names used in the same rule.
• Support multiple nesting
• Key which acts as shortname for nested rules, use same as lookahead keys.
