Hi
The generation of the method for the syntactic predicate of a rule with
a parameter is missing the parameter in its signature, which leads to a
compile error.

Here the CMinus grammar modified with the variable rule having a
parameter and conditionned by a syntactic predicate:
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------
program
scope {
List globals;
List functions;
}
@init {
$program::globals = new ArrayList();
$program::functions = new ArrayList();
}
: _declaration[2]_+
->
program(globals={$program::globals},functions={$program::functions})
;
declaration[int i]
: _(variable[i])=>variable[i]_ {$program::globals.add($variable.st);}
| f=function {$program::functions.add($f.st);}
;
_variable[int i]_
: type declarator ';'
-> {$function.size()>0 && $function::name==null}?
globalVariable(type={$type.st},name={$declarator.st})
-> variable(type={$type.st},name={$declarator.st})
;
Here the generated code
---------------------------------
