Would the following work, where you check the first argument?
import std.stdio;
void Log(string filename = __FILE__, T...)(T args)
{
static if (is (T[0] == typeof(null))) {
writefln("working without an object for %s", args[1 .. $]);
} else static if (is (T[0] == class)) {
writefln("working with object %s and %s", args[0], args[1 .. $]);
} else {
// Recurse
import std.meta : AliasSeq;
return Log!filename(AliasSeq!(null, args));
}
}
class C {
}
void main() {
Log(42, "hello");
auto c = new C();
Log(c, "cool");
c.Log("breeze");
}
The output:
working without an object for 42
working with object deneme.C and cool
working with object deneme.C and breeze
