I think that
auto x = new Derived!(typeof(stdout.lockingTextWriter()))(); //
note the parenthesis
should work.
But usually, you save the writer inside the object and make a
free function called `derived` (same as the class, but with
lowercase first). You define it this way:
auto derived(OutputRange)(auto ref OutputRange writer)
{
auto result = new Derived!OutputRange();
result.writer = writer; // save the writer in a field of
the object
return result;
}
void main()
{
auto x = derived(stdout.lockingTextWriter);
x.writeString("Hello world"); // the writer is saved in
the object, no need to pass it
}
Yes, the form you suggested works, thanks! And thanks for the
class structuring suggestion, it has some nice properties.
