[antlr-interest] Grammar reuse without dynamic binding

[Tomasz Uliński]

Hi,

I would like to reuse a grammar in this kind of way:
I have Pascal grammar 'pas.g' and I need to create Estelle grammar 'est.g'.
Some rules from Pascal must be extended in Estelle.

For example:
'pas.g'
assignment_statement:
     (variable_access | function_identifier) ":=" expression;


'est.g'
assignment_statement:
     pas.assignment_statement
   | module_variable ":=" module_variable;

I would like that alternative pas.assignment_statement in 'est.g'
assignment_statement rule expand to rules from 'pas.g', even though we
call rule in 'est.g' grammar and some of rules (variable_access |
function_identifier) ":=" expression are also redefined in 'est.g'.
I would like to get effect of namespace rather than inheritance.
Is there better solution than unique renaming all nonterminals in 'pas.g'?

Sorry for my poor English.
Best Regards!
