Hey there, I've experimented a little with UFCS today and ran
into a
problem.
My first question, which is kinda off-topic:
Why does D use the int type if you give it a number started
with
0x(hex), shouldn't it use uint for that ?
Good point, please file a bug on: http://d.puremagic.com/issues
Here comes the real question:
I've extended the int by one function, which is the following
(just
to represent the problem):
public static T read(T)(int address)
{
return cast(T)1;
}
It works perfectly if the function stands alone (is global),
but it
doesn't work if I put it into a class (because I want it to be
a bit
more organized) like that:
class CMemory
{
public static T read(T)(int address)
{
return cast(T)1;
}
}
I'm not able to write something like:
0x1212.CMemory.read!bool();
So the question is, how can I make it to be able to be used
like
this:
0x1212.read!bool();
but still organized within the class ?
I don't think UFCS works with qualified names right now. This
is a known
issue. The best way to solve this problem is to put your
function in a
separate module instead of a class, then importing the module
will pull
it into your current namespace and you can use it as above, yet
have it
organized by module (but not by class -- that's unfortunately
not
possible right now). Something like this:
----memory.d----
module memory;
T read(T)(int address) { ... }
----main.d----
import memory;
void main() {
0x1212.read!bool();
}
T
The thing is, that I already have other classes in that module
and I hate to mix global functions(global in the means of global
in the module) with classes.
I would separate them in different files, but sadly thats not
possible (as far as I can see, because you can only define the
module once, not like namespaces in c++).
