Hello,
I am new to D. According to that power of 2 rule I want to
reserve 2 sized chunks to my array, But how do I do that in a
struct? Say:
struct Stack(int){
int a[];
}
Where do I put that a.reserve(2);
Because right after the declaration of a I get an error
Error: unexpected ( in

Perhaps you want something like this:

You can set some kind of statically allocated array size:
struct S
{
int[] a;

You could allocate space inside a class itself with something
like this:
class Base {
int[] slice;
}
template Derived(size_t N) {
class Derived : Base {
int[N] array;
this() {
slice = array;
}
}
}
Base b = new Derived!32();
A bit pointless

Hi
I'm running Windows Vista 64 with dmd 2.062.
I have a simple program:

string[] temp_array;

{

Why isn't the memory deallocating?
P.S.;
I tried temp_array.clear() and destroy(temp_array), but nothing changed.
GC.minimize() may work.

Works for your test program under Linux but as the documentation says,
it is not guaranteed to have any effect at all.

Why isn't the memory deallocating?
The memory might be free, but still not released to the OS.
Especially in windows, when you free memory it still isn't freed
from
your process.
But you can reuse it in your program if the GC has collected it.
The correct test would be to copy and paste
I found this problem with a program that reads a large xml file
(25+ lines), then stores the lines in a string[], does a
comparison with another array and finally clears the original
array.
On the second or third file I always get an OutOfMemoryError,
