Standart syntax my funtion: data_type Name_function(parameters);
Examlpe:void GetCoordinate(string number);
My entity.name.function: match: '({{basic_types}}\s)([[:alpha:]])\(([[:alpha:]])\)' scope: entity.name.function
My basic_types: basic_types: 'String|Array|Map|Bool|bool|exception|string|Int|Float|Variant|Object|Message|message|void'
Plugin Outline cant see my function on it syntax. But he sees on the other. Probably an error in the expression ?
