Hi there;
I'm trying to get a scope of variables correspondant to method
declaration. but i'm geting this exception:
Exception in thread "main" java.util.EmptyStackException
at java.util.Stack.peek(Unknown Source)
at BTLParser.decl_var(BTLParser.java:462)
at BTLParser.inst_decl(BTLParser.java:727)
If i put only one ID it does work;
Here is a part of my gramar:
decl_var : TAG_START_OPEN 'var' {System.out.println("ambito " +
$decl_funcion::ambito);}
':' tipo ids+=ID (',' ids+=ID)* ('=' value)? TAG_EMPTY_CLOSE
{
System.out.println("Definir un hash map para var con scope");
System.out.println("ref "+$ids.toString() + " in ");
}
;
decl_funcion
scope {
String ambito;
}
: TAG_START_OPEN 'function' tipo_return '::' FN_ID
{$decl_funcion::ambito = $FN_ID.text;}
':' lista_params TAG_CLOSE lista_instrucciones TAG_END_OPEN
'function' TAG_CLOSE ;
Many thx in advance,
