Hi!
Placing multiple global dynamic attribute scopes to a rule is allowed
or not ? I've tried following grammar:
{{{
grammar ScopeTest ;
scope Scope1 {
int field_ ;
}
scope Scope2 {
int field_ ;
}
rule
scope {
int s_ ;
}
scope Scope1 ;
scope Scope2 ;
: subrule
;
subrule
: ID
;
ID
: 'a'..'z' | 'A'..'Z'
;
}}}
ANTLR 3.1b2 generates codes without errors, but seems to forget
pushing "Scope1". Generated code fragment is following:
{{{
public final void rule() throws RecognitionException {
Scope2_stack.push(new Scope2_scope());
rule_stack.push(new rule_scope());
try {
}}}
Regards.
