There was a way to define new types within templates and I think that I
have seen that demonstrated here in the newsgroups, but cannot find it
now. Can someone help me please?
I would like to do something like this:
template MyTemplate(T)
{
struct T ~ "Struct" // define FooStruct structure
{
int x;
}
class T ~ "Class" // define FooClass class
{
void bar(T ~ "Struct" t)
{
// ...
}
}
}
void main()
{
mixin MyTemplate!("Foo");
FooStruct t;
FooClass f = new FooClass();
f.bar(t);
}
Hopefully I am not mistaken.
I don't know for what you're asking, but there's absolutely no need to
use string mixins (see Trass3r's reply).
Instead you can just define a type inside the template, and then access
it by instantiating it:
template MyTemplate(T) {
struct Struct {
T x;
}
}
void main() {
MyTemplate!(int).Struct t;
t.x = 123;
}
You can use mixin MyTemplate!(int); to bring "Struct" into the module
namespace, and you can use e.g. "alias MyTemplate!(int) IntStruct;" to
save typing.
