Heya =)
I am building up a small IRC Client, but something goes horribly wrong.
I know WHATS wrong, but i don't know how to fix.
Code first:
| Code: | private import std.stdio;
private import std.socket;
private import std.socketstream;
private import std.string;
const int PORT = 6667;
void main(char[][] args){
char[] host = "irc.german-freakz.net";
// open a socket:
InternetHost ih = new InternetHost;
ih.getHostByName(host);
InternetAddress ia = new InternetAddress(ih.addrList[0], PORT);
TcpSocket sock = new TcpSocket();
sock.connect(ia);
char[] line;
SocketStream stream = new SocketStream(sock);
sock.send("USER DBot flippeh.de stockholm.se.quakenet.org :i iz a bawt\r\n");
sock.send("NICK DBot3\r\n");
while ((line = stream.readLine()) != null) {
if (!stream.eof()) {
writef("%s\n", line);
}
}
} |
Okay, its connection and outputting really nice.
But then there is the problem. If the line to read contains german characters (ae oe ue), it crashes. How do i fix that? =/ |

D's standard output can only handle utf8.
you try to output something other than utf8.
you need to transform your strings. simplest solution: just escape everything that's outside of the range of ascii (0-127).

Erm well, i cannot escape them...
When i connect the server sends me a dozen of MOTD messages etc.. i can't modify them.. as soon as they arrive, the application dies.
Edit:
| Code: | while ((line = stream.readLine()) != null) {
try {
if (!stream.eof()) {
if (!line < 127) {
writef("%s\n", line);
}
}
} catch {
}
} |
Seems to work, as any message containing the stuff gets simply ignored. How can i escape it, tho? |

you change the string before outputting it.
walk it, change chars that are >127.

| Dirclib (IRC library for D) handles this nicely, by converting invalid UTF-8 from latin-1 to UTF-8. Many clients do similar. |

I can't find ANY substring method..
How can i check single signs in a char?
... god, D is so hard to start for someone who doesn't know everything about it.
Edit: Got it.
But its not working...
| Code: | for (int i = 0; i < szLine.length; i++) {
if (cast(int)szLine[i] > 127) {
writef("Invalid: %d", szLine[i]);
}
} |
It doesnt output anything |
