The link you provided is invalid (is your repository private?), but I'll try my best to help. This is a problem with your system being unable to locate "msvcr100.dll", which it needs to load for your application. From what I have found from a quick search, this .dll is a part of Microsoft Visual C++. You should try installing Visual C++ and see if that solves the problem. Best

That's only true with startsWith, because it avoids decoding in the case where the two strings have the same encoding (e.g. it's not nothrow if you compare a dstring and a string). Presumably, skipOver could be made to do the same, but no one has done so. - Jonathan M Davis

Almost anything involving strings isn't going to be nothrow, because front
and popFront throw on invalid UTF. To really fix that, we'd need to get rid
of auto-decoding. You can use std.utf.byDchar to wrap the string in a range
of dchar which replaces invalid Unicode with the replacement character
instead, which means that no exception gets thrown, but it also means that
if you hadn't previously validated the Unicode, you could end up processing
invalid Unicode without realizing it. How much that matters depends on what
you're doing. Ideally, all strings would just be validated when they were
created, and then it wouldn't be an issue, but any code that decodes the
code points would still have to deal with invalid Unicode in some manner
(though if we decided that it was the responsibility of the caller to always
validate the Unicode first, then we could use assertions). For better or
worse, the chosen solution when ranges were first put together was to throw
on invalid Unicode, which basically makes it impossible for functions that
process strings to be nothrow unless they go to the extra effort working
around auto-decoding. If we're ever able to remove auto-decoding, then
that's no longer an issue for all string processing functions, but it's
still going to be an issue for any code that calls functions like decode or
stride. They're either going to throw or replace invalid Unicode with the
replacement character. Which approach is better depends on the code.
In any case, as long as auto-decoding is a thing, you'll have to use
wrappers like byDchar or byCodeUnit if you want much of anything involving
strings to be nothrow.

But not sufficient. :) IDEs like VS Code have a way of describing what

How to use classes from another d files
Hi all,
I am new to D. But some fair experience with vb.net. I was
playing with D classes. I wrote a class in a D file.
The file name is "classFile.d"
```D
class TestClass {
int myIntVar;
string myStringVar ;
this(int miv, string msv) {
this.myIntVar = miv ;
this.myStringVar = msv ;
}//End this
}//End Class
```
And i wrote my main function in another file named "caller.d".
Both these files are in same folder.
```D
import std.stdio ;
void main() {
import classFile ;
TestClass tc = new TestClass(37, "Sample String") ;
writeln(tc.myStringVar) ;
tc.myIntVar = 45 ;
writeln(tc.myIntVar) ;
writeln("its over..") ;
}//End main
```
This is the error message i got.

You can't use rdmd with dub, but for simple scripts you can use

Here an example, save it as example.d:

"aws-sdk:core": "1.0.0",

void main()
{
auto client = new AwsClient();
auto s3 = new S3Service(client);

On linux you could start this file using command

Or with command ```dub example.d```.

Thread synchronization context
Hello everyone,
Recently, a few days ago I discovered dlang and I really like it.
It's a programming language which meets to my idea of what a
modern programming language should look like. I decided to do one
project in it.
Now I am addressing one problem. I have two threads, one main and
the other for a communication. How can I call a method from a
communication thread in the context of the main thread? Something
like the SynchchronizationContext class in c#.
An example:
alias PacketEventHandler = synchronized void delegate (Object
sender, PacketEventArg e);
public class TcpClient : Thread
{
public this()
{
_socket = new Socket(AddressFamily.INET, SocketType.STREAM);
_socket.blocking = false;
PacketReceived = _packetReceived;
super();
}
protected void Execute()
{
_socket.connect(new InternetAddress(_address, _port));
while (!_terminated)
{
_socket.send(dataToSend);
ubyte[] receivedBuffer = new ubyte[_packetSize];
auto received = _socket.receive(receivedBuffer)
if (PacketReceived !is null)
PacketReceived(this, new PacketEventArg(receivedBuffer));//that
delegate I would like to call from the context of main thread
}
}
public PacketEventHandler PacketReceived;
void client_packetReceived(Object sender, PacketEventArg e)
{
writeln("received byte0: ", e.dataPacket[0]);
}
}
Thank you for any answers

Dub settings can be at times intimidating, but still give it a

Thank you Arun, that is very helpful!
Do you have also some example which use some other than default
library ?
I see there is quite comprehensive description how to use dmd
with dynamic libraries
https://dlang.org/articles/dll-linux.html
But there is nothing how to integrate it with dub and deb.json (I
really like DUB, it's one of the best improvements over C/C++
enviroment I noticed)
Also where is RDMD in the equation? I really like the idea run
binary programs like:
#!/usr/bin/env rdmd
import std.stdio;
void main(){
writeln("Hello, world!");
}
But I cannot find any documentation how to use rdmd with any
libraries/dependencies and dub.json ? Not even statically linked,
not to say dynamic.

The exception is OpenGL, for which there is no static binding. The dynamic bindings add the overhead of the function pointer declarations when linked. It's insignificant for most of them. The biggest bindbc-opengl, depending on how many extensions you configure (it's extremely high for DerelictGL3 most of the time, as it tends to pull in more extensions). 2) I'm more concerned about how to D compiler links dependencies when it compiles simple .d program (with lot of dependencies). When using dub, it depends on the package configuration of each dependency. All of the Derelict and BindBC packages, for example, are configured to build as static libraries. It didn't (and doesn't) make sense to me to compile a binding as a shared library. Dub packages can also be configured as shared libraries, or simply as "library" (I haven't investigated what that means). Some might provide custom subconfigurations to choose static or shared. The biggest overhead with DMD output tends to come from the standard library. On Windows, the static library the only option. IIRC on Linux it's necessary to pass -defaultlib=libphobos2.so to DMD to link the shared lib. I don't know how LDC handles it.

You should try to use https://github.com/BindBC/bindbc-opengl

And as far as I know derelict should be replaced by bindbc

OK, thanks. That is useful to know. But just to not turn the

1) I'm not speaking about OpenGL and SDL specifically (that was

2) I'm more concerned about how to D compiler links

I think if I can make it link everything dynamically, It would
considerably reduce both size of binary target (whether it is
executable or .so) and compilation speed (since it would not
re-compile dependencies).
What I want is to recompile and run quite large
programs/projects composed composed of many little
sub-programs/sub-libraries from Python+D in fast cycles (<< 1
second), because that would make debugging workflow much more
pleasant and efficient (in comparison to Python+C/C++ or Julia).

If you can do some more research into this and confirm it then,
please file a bug report.
As I understand - yes. It doesn't work with immutable object.
Also I see the same problem with 'const' and 'shared' object:
shared values = sort(cast(wstring[])["й", "ц", "ук", "н"]);
const values = sort(cast(wstring[])["й", "ц", "ук", "н"]);
values.contains("ук"w).writeln; // error
So you think it is a bug in compiler?
