enum Bar = "Bar";
@("Foo") @Bar int x;
pragma(msg, __traits(getAttributes, x));
This prints: tuple("Foo", "Bar")
How do you run code only if "Bar" is associated with a symbol
like x?
I was hoping something like this:
pragma(msg, hasAnnotation!(x, Bar));
Where getAnnotation from
(http://forum.dlang.org/thread/[email protected])
was written as:
template hasAnnotation(alias f, Attr) {
bool helper() {
foreach(attr; __traits(getAttributes, f))
static if(is(attr == Attr) || is(typeof(attr) == Attr))
return true;
return false;
}
enum bool hasAnnotation = helper;
}
I am missing how this can be used.
Thanks
