Hello, I'm trying to use templates to define several methods
(property setters) within a class to avoid some code duplication.
Here is an attempt:
class Camera
{
private:
Vector4 m_pos;
float m_fov, m_ratio, m_near, m_far;
bool m_matrixCalculated;
public:
void SetProperty(Tin,
Thanks Steven and Daniel for your explanations.
mixin template opAssign(alias Field) {
void opAssign(Tin)(auto ref Tin param) @property pure
@safe
{
Field = param;
m_matrixCalculated = false;
}
}
mixin opAssign!(m_pos) pos;

I just saw this post, which is essentially the same question as
Basile Burg's. I hope that a college (in France?) is teaching D
and that this is a homework assignment. Cool stuff! :)
Maybe using templates to create properties is a bit overkill in
this example. But I could not solve what I
I tested it on linux (64-bit distro), and it segfaults as well:

Thanks for your replies, John and Ali. I wasn't sure I was clear.
I'm going to try to see if I can fit Ali concept (totally lazy,
which is what I was looking for) within ndslices, so that I can
also use it in 3D and apply window() function to the result and
mess around with it.
Hello,
I come from the C world and try to do some procedural terrain
generation, and I thought ndslice would help me to make things
look clean, but I'm very new to those semantics and I need help.

Hello,
I've been working on some kind of allocator using a dynamic array
as a memory pool. I used emplace to allocate class instances
within that array, and I was surprised to see I had to use
GC.addRange() to avoid the GC to destroy stuff referenced in that
array.

It's more a general meta-programming question than a specific D

Thanks for your answer.
However I cannot use variants, as I have to store the components
natively in a void[] array (for cache coherency reasons).
So I found a way to solve that problem:
Druntime uses this for its translation of POSIX header files:
https://github.com/dlang/druntime/blob/master/src/core/sys/posix/config.d
An example:
https://github.com/dlang/druntime/blob/master/src/core/sys/posix/sys/resource.d#L96
Ok, I see. Thanks!

I'm working on a C++ project requiring an XML parser. I decided

As our project uses a gcc tool-chain, I naturally use GDC (GCC

Cool, thanks.
Unfortunately, with that implementation, I need to know the
maximum size for the array. It works for that particular example,
but in the context of an XML file analysis, it's a bit awkward.
