Thanks for the tip. std.range.enumerate makes a big difference:
foreach (i, element; MyRange(42).enumerate) {
// ...
}
versus sequence!n and zip:
foreach (i, element; zip(sequence!n, MyRange(42))) {
// ...
}

foreach (i, element; MyRange(42).enumerate) {
// ...
}
versus sequence!n and zip:
foreach (i, element; zip(sequence!n, MyRange(42))) {
// ...
}
But it's better to not use automatic unpacking of tuples. See
issues 7361 and especially 9817.

Re: Really in need of help with std.container.array.d
hm, the problems seams to be that inout Array is not becoming const Array and friends. A blunt force solution would be to create a range as Range!(ReturnType!Array...)(cast(Array!T)this, low, high); and then do the correct casts in Range. The ReturnType would be the ReturnType of opIndex of the Range type and the Array would be stored as plain array without any qualifier. other than that I'm not sure how to go about this.
is there any hack to determine if variable is __gshared?
Hello.
i need to enumerate all module variables of the given types (it's easy,
this is not the question) and make list of only __gshared ones. of
course, i'm talking about CTFE.
is there any hack/trick to determine if variable is __gshared? or if it
is a thread-local, for that matter?
i added 'isGShared' trait to my compiler, but i'm not expecting from
others to do the same. ;-)
the only hack i invented is this abomination:
int v0;
__gshared int v1;
enum isGShared(alias var) =
!__traits(compiles,
mixin({auto a___ = function typeof(~var.stringof~
) () @safe { return ~var.stringof~; };}));
pragma(msg, isGShared!v0); // false
pragma(msg, isGShared!v1); // true
sure, it's very limited, and we must do alot of checks before using it.
it *SEEMS* to work, but i not tested it very well.

Can someone explain how glfw3.dll gets created?
I have a simple GLFW3 program running in Visual D integrated
shell, that kept aborting at DerelictFLFW3.load() with a failed
to load the shared libraries: glfw3.dll.'
So I found a glfw3.dll somewhere and moved it into the project
folder (I know this is bad technique) and that fixed the problem.
But now I'm wondering were this glfw3.dll came from.
I rebuildt the DerelictGLFW3 with dub as per the instructions.
E:\DerelictGLFW3-masterdub build
Building derelict-glfw3 ~master configuration library, build
type debug.
Running dmd...
And I see
E:\DerelictGLFW3-master\source\derelict\glfw3\glfw3.d which is
used for compile time.
And the
E:\DerelictGLFW3-master\lib\DerelictGLFW3.lib which is the static
library required at link time.
But I couldn't find any glfw3.dll under the
E:\DerelictGLFW3-master path.
I did however, find these lines in the DerelictGLFW3/glfw3.d code:
...
static if( Derelict_OS_Windows )
enum libNames = glfw3.dll;
. . .
class DerelictGLFW3Loader : SharedLibLoader {
public this() {
super( libNames );
}
protected override void loadSymbols() {
bindFunc( cast( void** )glfwInit, glfwInit );
bindFunc( cast( void** )glfwTerminate, glfwTerminate );
bindFunc( cast( void** )glfwGetVersion, glfwGetVersion
);
bindFunc( cast( void** )glfwGetVersionString,
glfwGetVersionString );
bindFunc( cast( void** )glfwSetErrorCallback,
glfwSetErrorCallback );
...
But I don't believe this will create the glfw3.dll file? If I'm
correct, how, when and where is glfw3.dll created.
thanks as always.
Re: Can someone explain how glfw3.dll gets created?
Derelict provides bindings to C libraries, and loads them at runtime. So glfw3.dll is actually an existing C library (you can get it at http://www.glfw.org/download.html), which Derelict provides bindings for. Derelict / your code does not generate the actual dll.

Derelict-glfw3 is just d bindings and a loader for the glfw3
library. The actual implementation of glfw (i.e. what you would
find in glfw3.dll) is a separate project, which you can find the
source for here http://www.glfw.org
