Hi,
I just wonder why with (auto p = new ...) is not working.
It would be some syntax sugar in this scenario:
with (auto p = new Panel())

parent = this;
text = bla;
with (auto b = new Button())
{
parent = p; // Here p is needed
text = bla2;

Re: How to export a deduced template type to the enclosing scope?

I think similar questions were asked by others in different

I played with core.thread.Fibre a little bit. As others have

I wonder whether there is a clever trick to pull out a deduced
type from a template. I don't think it is possible, because
there may be many instantiations of the template and it would
not be clear which one to pull out. (I don't think there is any
way of getting all of the instantiations of a template because
the compiler has only a partial view of the program at a time.)
However, what if there is exactly one instantiation allowed?

It simply removes leading/trailing white. There's a version in std.algorithm which is more generic, but it accepts either a predicate, or an element, but not a range. Unfortunately, there is no generic function that allows striping of a specific ending range (though there are ways to either detect it, or strip it from the end). If you want something generic, then: string path = myFile.doc; string extension = .doc; if (path.endsWith(extension)) path = path[0 .. $ - extension.length]; Would work.

Don't do `path ~ \\ ~ filename`. Instead, use
std.path.buildPath. It's more portable, faster, and convenient.

Any kind of looping control structure would work. I'd advocate

You mistyped the function name, it's getFileName (capital N), and

Re: Trying to get Derelict.opengl3.gl3 and derelict.glfw3.glfw3 to work together
Whoops, I just saw that my earlier answer was totally inaccurate. I was on my phone at the time, so didn't look at the code in detail. No big deal, figured you just missed it / auto response to this kinda question. I did my best to google this question, but wasn't really sure where to begin. Yes, ##opengl on freenode has good tutorials and examples in the topic. If you've been reading NeHe, drop it. NeHe is severely out of date and anyone still recommending it probably don't know what they're talking about. Here's some links: http://www.arcsynthesis.org/gltut/ https://github.com/progschj/OpenGL-Examples https://github.com/g-truc/ogl-samples Exactly the kinda thing I was looking for. Thanks for the heads up about NeHe. Note that modern OpenGL is a bit more involved to get something on the screen. You'll be writing a lot more boilerplate in the beginning, but a lot of the modern features are definitely worth it. I came from web development, you're meaning to tell me there's coding outside of writing boilerplate? Jokes aside, figured if I took the time to learn a modern language, I'd be consistent with adding in newer technologies :)

I can't understand how to use strip? For example I would like to cut

Error: no overload matches for stripRight(C)(C[] str) if
strip doens't work that way. It simply removes leading/trailing white.
There's a version in std.algorithm which is more generic, but it accepts
either a predicate, or an element, but not a range.
Unfortunately, there is no generic function that allows striping of a
specific ending range (though there are ways to either detect it, or
strip it from the end).
If you want something generic, then:
string path = myFile.doc;
string extension = .doc;
if (path.endsWith(extension))
path = path[0 .. $ - extension.length];
Would work.
find() and friends can be used:
import std.algorithm;
void main()
{
string path = myFile.doc;
string extension = .doc;
path = findSplitBefore(path, extension)[0];
assert(path == myFile);
}
And three retro()s make one modern(): :p
import std.algorithm;
import std.range;
void main()
{
string path = myFile.doc;
string extension = .doc;
path = findSplitAfter(path.retro,
extension.retro)
[1].retro;
assert(path == myFile);
}

Jokes aside, figured if I took the time to learn a modern language, I'd be consistent with adding in newer technologies :) In that case, here's some two things on the way that may not be all that intuitive for a web developer when it comes to dealing with OpenGL, as they are quirks stemming mostly from how C works: 1. When you need to pass an array of some sort to an OpenGL function, remember to use foo.ptr, not foo. foo.ptr will get you a pointer to an array that the rest of the world, not just D, understands. 2. The OpenGL spec mandates that empty error logs for shader compilation are to report length 0, but if you ask on an nvidia machine about the length of its empty error log, it will reply with length 1. This is because nvidia just send the length of the string in all cases, which for empty C strings is 1 due to the null-byte. I hope this helps you along, good luck!

1) You need a this template parameter:
string[] getPropertyNames(this MyType)()
2) Now, replace all typeof(this) expressions with MyType below.
/*string[] getPropertyDuplicate()
3) Same here:
string[] getPropertyDuplicate(this MyType)()
And it works! :)
class A {
mixin MyTemplate;
@property int zzz()
{
return 42;
}
}
void main() {
auto a = new A();
import std.string;
assert(a.getPropertyNames() == [ zzz ]);
assert(a.getPropertyDuplicate() == [ zzz ]);
