dub + local dependencies
WARNING: A deprecated branch based version specification is
used for the dependency xyz.
Please use numbered versions instead.
Also note that you can still use the dub.selections.json file
to override a certain dependency to use a branch instead.
The problem is: xyz is a local package and therefor I don't know
how to specify its version. So in the dub.json of the package abc
requiring xyz is written:
"dependencies": {
"xyz": "~master"
},
Is there a cleaner solution?

So in conclusion it seems the problem is in VisualD installation which doesn't set the path properly even though it recognizes where DMD is installed. Hope the author takes a look at this problem so beginners wanting to try D don't give up on a problem like this. VS 2017 uses a "private" registry that the Visual D installer doesn't have access to. I'll change the registry location in the next release. Please note that the next dmd installer will also detect VS2017 and setup directories correctly in sc.ini: https://github.com/dlang/installer/pull/227 Today I saw that a new DMD version had been released.

That's true. But when D's GC does not trigger early enough, my program runs out of memory (due to the 2 GB limit of 32 bit process), x64 solves this more or less. As a side note: I am talking about allocating huge arrays. And, again, Visual Studio is not required if you want to target Win64 - only the necessary toolchain components (linker and C runtime), which you can also obtain from an SDK. So you are telling me "not working at all" is not worth releasing a fix? xD Again, everything should be already working. We are talking about a convenience feature that automatically sets up the D compiler's configuration file, nothing more. That's all there is to the "integration". You can trivially do the same thing by hand, or set up your environment accordingly - all in a fraction of the time it took you to write these pointless complaints on this forum. I admit, you are right in some points. Nevertheless, have you ever tried letting a novice configuring this stuff? The 'sc.ini' is neither easy to read nor logic.

My message was neither addressed directly to anybody of the volunteer contributors (I have a huge respect of them and their great work), nor to anyone at the D Foundation directly. I just wanted to critize the whole release cycle stuff itself. I mean, if for any circumstance, e.g. like the VS2017 thing (which did not suddenly appear from one day to another anyway), the whole software cannot be used without larger fiddling (in this case: setting up NSIS + plugins), it seems quite strange to not simply update the installer, which would be a work for a few minutes - and after that everybody would be happy. But to be honest, I don't think that this is a problem of D. More or less, this is something that appears everywhere in the world of open-source.

Howto catch SocketOSException?
How do you catch an std.socket.SocketOSException?
The following does not work, as the exception occurs anyway and
leads to a crash:
import ae.net.asockets;
void main(string[] args)
{
TcpServer tcp = new TcpServer();
try
{
tcp.listen(2345, "127.0.0.1c");
// '...c' makes the IP address invalid
}
catch (std.socket.SocketOSException e)
{
return;
}
catch (Exception e)
{
return;
}
socketManager.loop();
}
Output:
std.socket.SocketOSException@std\socket.d(975): getaddrinfo
error: Unknown Host

Silly me! Now I used Xamarin's Find-Usage-Feature, found one usage in ae and realized that there is no reason for using the keyword `new`, as Data is a struct (and so one does not need `new` unlike in C#) ...

About void[] and asockets
For sure, some might know ae. I am trying to use it as TcpServer. I got almost everything working fine concerning connection establishment and disconnecting. But there is one thing that makes it hard for me to understand, how to handle data. https://github.com/CyberShadow/ae/blob/master/net/asockets.d Well, what are these void-arrays for real? I mean, they contain data what does not make them really void, does it? And how to I get received data out of Data.content[]? How to use TcpConnection.send()? E.g. for sending a string?

ah okay, thx
But what about this?
class A
{
private:
int a;
int b;
public:
int c;
int d;
}
or
class A
{
private
{
int a;
int b;
}
public
{
int c;
int d;
}
}
Class Order Style
How to sort the members of a class?
like:
1. properties
then
2. private 3. methods
4. ctors
... and so on. are there any recommendations?
And what is better?
class A
{
private:
int a;
int b;
public:
int c;
int d;
}
or
class A
{
private
{
int a;
int b;
}
public
{
int c;
int d;
}
}
