Same thing in D without the semicolon. :)

Like in Java and C#, class variables are object references in D. So, the 
following is sufficient:


SpriteRenderer Renderer;  // Although, I would name it 'renderer'

However, unlike C++, that variable is thread-local, meaning that if you 
have more than one thread, each will have their own variable. If you 
really need it, in multithreaded code you may want to define it shared:


shared(SpriteRenderer) renderer;

But then you will have to deal with thread synchronization.

It was my understanding that the built-in sort did indeed sort individual
chars, so if that's not currently the case, I expect that someone fixed it
at some point. Still, it should be removed from the language at some point.

Two options:

b) Import sort() under a different name:

import std.algorithm: algsort = sort;

  arr.algsort


Yep. The sort property on arrays will likely go away eventually, but until

Do you mean property sort would sort individual chars? However, the 
following program indicates that it may have been fixed (i.e. made 
Unicode-aware):


import std.stdio;

void main() {
auto arr = "çöüabc".dup;
arr.sort;

// (Not correct for a particular writing system but
// that's beyond the point. It's still a correct string.)
assert(arr == "abcçöü");

foreach (c; arr) {
writefln("%02x", c);
}
}

Prints:

61
62
63
c3 <- Out of order
a7 <- etc.
c3
b6
c3
bc

Perhaps, this was an independent change? More likely I've misunderstood

Apparently, gdmd expects gdc to be in the same directory as itself. Once 
Orkhan finds out where gdc is on the system, the following should work:


$ sudo ln -s 
/home/acehreli/x86_64-pc-linux-gnu/bin/x86_64-pc-linux-gnu-gdc 
/usr/local/bin/gdc


Orkhan, replace 
/home/acehreli/x86_64-pc-linux-gnu/bin/x86_64-pc-linux-gnu-gdc with the 
gdc binary that you have. e.g. if it's under /usr/bin, then do the 
following:


$ sudo ln -s /usr/bin/gdc /usr/local/bin/gdc

Ali

P.S. I've just installed gdc after downloading it from its download site 
( http://gdcproject.org/downloads ) with the following two commands:


  unxz the_file_you_downloaded
  tar xvf the_file_you_unxzipped

Those commands created the following directory in my case.

  /home/acehreli/x86_64-pc-linux-gnu

That's why my gdc is named 
/home/acehreli/x86_64-pc-linux-gnu/bin/x86_64-pc-linux-gnu-gdc above.

What does `which gdc` print? If it says something like "which: no

Otherwise, you can use the following as a quick workaround:


sudo ln -s `which gdc` /usr/local/bin/gdc

The proper solution is to find out why gdmd insists on using that 
non-existing path instead of relying on $PATH lookup, and fix it.

Yep. The sort property on arrays will likely go away eventually, but until
it does, those are your options. But at least now it warns you. Previously,
it just silently used the sort property, which does the wrong thing for

The two `Test` templates are completely unrelated to each other.

You can bring them together with `alias`:


module one;

alias Test = two.Test;
struct Test(T) {}

void testing(T)(Test!T t) {}


`one.testing` still only accepts `one.Test`, but `one.Test` now includes

Sorry to have misled you. Apparently, those are gcc compiler 
switches that are not supported by dmd.

That's the only solution then.

Yes I have seen that page. But I don't know how to make that . I 
think I need to upload all files then unzip then just type make ? 
could you please let me know. Thanks.

I think you need to install gdmd:

  https://github.com/D-Programming-GDC/GDMD

Alternatively, assuming that you have dmd installed, you can 
try replacing gdmd with dmd in your Makefile.

I changed all gdmd to dmd and still not getting result . the

Specialized template in different module

[John via Digitalmars-d-learn]

If I define a template in one module, and specialize it in a 
second module, the compiler doesn't like it when I try to call a 
function using the template.


  module one;

  struct Test(T) {}

  void testing(T)(Test!T t) {}

  module two;

  struct Test(T : int) {}

  void main() {
Test!int i;
testing!int(i);
  }

Output:
  error : testing (Test!int t) is not callable using argument 
types (Test!int)


If I put everything in the same module it works. So are template 
specializations limited to the same module?

Now I'm living in much smaller place and will ask about the possibilities
to order, although I remember when I was living in the capital (Zagreb),
ordering from the shop ended up as double expensive in comparison with
e.g. Amazon order.

I'm also not excited with the their business behaviour, but, otoh, do
not have much choices except using some other online retailer.

Ahh, I se..

I'm just curious if the above applies here. ;)

It sounds good, although I'm taking it with pinch of salt until I check
it out.

There are nice trains in Europe, but poor connections in Croatia.

There are other circumstances to overcome (taking care of our small
daughter, while wife is working at emergency and you might heard there
is lack of doctors here and they have to work extra hours etc.)

However, let me thank you for the book which I know, from personal
epxerience, is always a labour of love and cannot be properly paid back,
but, at least, be happy that it created one new (old) user. ;)


Sincerely,
Gour

p.s. I'll inform you about my decision from where to get the book.

Re: Where do I learn to use GtkD

Each programming language will have a slightly different idiomatic way
of working with GObject introspection, so it is no surprise that the
Python API to GTK+3 is somewhat different to the D one. (And then there
is gtkmm.)

The D source binding creation appears not to deal with the comments
(which would be very hard I suspect) so they retain their original C-
ness. This can be very irritating, and indeed annoying. However, at
least there is:

http://api.gtkd.org/src/gtk/AboutDialog.html

Do not be confused by the URL or the start point, it is actually the
full API, just with a weird UX. Mayhap some of us should club together
and make this better. 

The demos in:

https://github.com/gtkd-developers/GtkD/tree/master/demos

are OK for initial learning, but seemingly rapidly run out of
usefulness. Which leads to my feeling that there are far too few
examples of GtkD use out there that are:

a. Idiomatic.
b. Up to date.
c. Reviewed and recognized as good.

As Gerald points out he has a couple of applications that are useful
for various approaches and techniques.

https://github.com/gnunn1/terminix

> blogs post, etc please

There is my own adventure into using GtkD, especially the GStreamer
binding, I have no idea if this is good code, and it may soon have to
stop being FOSS (and so will stagnate).

https://github.com/russel/Foscam_Client

What we need here is a collection of people reviewing each others GtkD
code and having a listing board somewhere on the GtkD site of all the
codes available and what they show. It is the annotations as much as
the code itself that is needed for learning.

Without comparative review, we may end up propagating bad code and bad
GTK use.

So rather than just email as here, we should be looking to create a
"living document" on the wiki – not an historical type thing but an
always up-to-date, curated document.

c_long maps to the target long which evidently is not 64-bit on

meaning you can't seek longer than int.max.
 if you cant't find _fseeki64 try looking in the windows section.
Glad you got it working on arch.
