Hi Graham
Does this give you what you want ?
localVariableDeclaration
: LOCAL! variableDeclarationList
;
variableDeclarationList
: variableDcl ( ',' variableDcl )* -> ^(LOCAL variableDcl)+
;
If you also use the variableDeclarationList rule for non-local
declarations you could give it a parameter...
localVariableDeclaration
: LOCAL! variableDeclarationList[LOCAL]
;
variableDeclarationList[int type]
: variableDcl ( ',' variableDcl )*
-> {type == LOCAL}? ^(LOCAL variableDcl)+
-> ^(OTHER variableDcl)+
;
