Hi.
I want to somehow list members of a class in the order of their
declaration. The immediate goal is to generate a few functions,
like the "default" constructor for structs but only with all the
fields, or the "reader" function, but I'm interested in the
general question as well.
I can g
Hi All,
In my adventure to learn a little bit of D coming from C++ I am
now faced with the following problem:
I have read about "cross-module overloading", ยง5.5.2 page 146 of
Andrei Alexandrescu book.
That makes sense to me and this is interesting.
As a concrete example here the scenario: I
The line:
assert(isnan (c.curActivation), "cell has unexpected curActivation:
%s".format(c.curActivation));
throws the exception:
core.exception.AssertError@cell.d(285): cell has unexpected
curActivation: nan
and I've looked at it backwards and forwards and don't understand why.
It's
Hello,
how can I copy class when I have pointer to the parent of it?
eg.
class Foo {
int m_a;
this(const(Foo) other) {
m_a = other.m_a;
}
}
class Bar : Foo {
int m_b;
this(const(Bar) other) {
super(other);
m_b = other.m_b;
}

How did you set it? There are like billions of different NaNs.

Honestly, I'm surprised that the compiler let you alias
std.algorithm.comparison.min, because it's a templated function, and in the

But this implementation of dup doesn't work.
The dup will need to be a virtual function in the base class for
best results, reimplemented in each child class.
You could also copy the bytes using runtime type info...

Hi, what is a correct (and simple) way to create an singleton?
This is how I see that now:
```
class ApMessageRouter
{
static ApMessageRouter instance = null;
private this() { } // for disable constructor to use from
outside

Don't bother with gdc at this point. Unless there's a development vers
