Asian characters are not printed propely in console
I'm sorry for posting in the wrong place. I attached screenshot of my code and the result. As you can see, Korean letters get changed after compilation. This problem doesn't happen with user input(from readln() method). Should I use different type and prefix or suffix similary to C++? begin 644 캡처.PNG MB5!.1PT*@h-24...@```5```$.`8]L%0G`7-21T(`KLX MZ01G04U!``QCPO\804)$A9P``#L,```[#`=OJ0``#$^241!

Place the following code anywhere at the top level in your program:
version(Windows)
{
import std.c.windows.windows : SetConsoleCP, SetConsoleOutputCP;
static this()
{
SetConsoleCP(65001);
SetConsoleOutputCP(65001);
}
}
This code should really be in the standard library, I think.

terminology: l-value r-value
Hello, I'm bluffed by the 2 terms l-value r-value used in C-line language common terminologies. I think I guess what they mean, but I don't understand the need for such absconse idioms. Why not: l-value - variable r-value - value (or expression) ? I guess (*p) is considered an l-value. Indeed, it's a special way of denoting a variable, matching the special case of a pointer. If correct, this requires slightly extending the notion of variable (and/or of identifier). On the r-value side, I cannot find anything that makes it a distinct concept from the one of value, or of expression. Explanations welcome, thank you, Denis -- -- -- -- -- -- -- vit esse estrany ☣ spir.wikidot.com

Both lvalues and rvalues are values, both can be expressions, and lvalues doesn't have to be variables. Perhaps a better terminology could have been chosen, but changing them doesn't provide real benefits, as far as I can tell.

Explanations welcome, thank you, Denis lvalue stands for left value, rvalue stands for right value. They describe which side of the equation they are on: lvalue = rvalue; Why these terms instead of something more natural? Well, I have no idea :) If I were to guess, it would be that no natural term could exactly describe the meaning, and also that using natural terms are subjective. There's no mistaking what lvalue and rvalue mean becausey they are defined by the language itself. I'm sure Walter probably knows the origin, l and r values are really compiler terms, and he's been writing compilers for a long time. -Steve

Therefore it really should include an import of std.algorithm explicitly for both clarity and long term reliability. Bryce.

joining multicast groups with std.socket
I am trying to listen to a multicast group using the std.socket library. I have looked at the documentation but I do not see a way to join a multicast group. The code I have so far is pasted below. I am looking for the IP_ADD_MEMBERSHIP socket option (along the lines of http://www.cs.unc.edu/~jeffay/dirt/FAQ/comp249-001-F99/mcast-socket.html) and can't find within the library. Let's assume I am trying to listen to 225.0.0.37/12345 Can someone help me with a snippet on some d code that will do this? I appreciate the help! Peter auto socket = new UdpSocket(); auto address = new InternetAddress(12345); socket.bind(address); auto multicastAddress = new InternetAddress(225.0.0.37); /// The below naturally does not work and I can't seem to find // How do I join the multicast address above? byte[256] buffer; int read = socket.receiveFrom(buffer); printf(Received bytes %i, read); return 0;
