Hello everybody.
Quick question, is there anything like C#'s partial classes in D?
Mars
As already said template mixins are close to partial classes.
A snippet. HTH
import std.stdio, std.cstream;
void main(string[] args)
{
auto bar = new Bar();
when i do that auto x = [1, ha];
i have an error Error: incompatible types for ((1) ? (hgh)):
'int' and 'string'
if there any method to combine different data type?
In Java and C++, I can do something to the effect of:
try
{
//Some code
}
catch (Exception1)
{
}
catch (Exception2)
{
}
//etc...
However, this doesn't seem to be possible in D. What is the idiom for handling
a case where multiple exceptions of different types may be thrown?

I think you could catch a common baseclass like Exception and test if it's
a specific Exception by casting.

I believe it does it linearly though, so it will use the
first catch that matches.
try {}

So from what I've found searching the newsgroup and my own
experimentation, the best way to accomplish compile time printing
is to do something like this:
string ctMain()
{
//evaluate and return the final result string
}
enum result = ctMain();
pragma(msg, result);
I'm not a fan of having
I suppose that works, though it does seem a little hackish (and I'm pretty sure
it's considered bad form in Java). What was the line of reasoning for omitting
this (to me, at least) extremely useful construct?

Why not?
import std.stdio;
class Exception1 : Throwable { this( string s ) { super( s ); } }
class Exception2 : Throwable { this( string s ) { super( s ); } }
void foo() {
throw new Exception1( foo );
}

You might want to check out std.variant. It's Variant type
Is there a direct analog to sub() in D2? The replace() function in regex
seems a bit overkill for what I need. I just want to substitute one string
for another.

There are any RPC module for D ??

You could throw SpecialException in the handler for Exception. So it's
legal code.

I know a ctwriteln never really caught on,
There is an open pull request about it. And I think we'll have it in D.
A problem is, that ctwriteln too adds a newline... :-(

Jonathan M Davis:
I do think that having the compiler complain when one catch block hides
another makes a lot of sense, but I think that that's as far as it should
go. It's the programmer's job to fix their code, not the compiler's.
I agree. Do we create a new diagnostic enhancement request
In Python int() and float() convert a string into a number even if it contains
some whitespace before and after the number:
s = 12\n
int(s)
12
float(s)
12.0
In D to!int( 12\n) gives a run-time error. So time ago I have weakly asked
Andrei to change to!int, to let it ignore leading and
I see no reason why the compiler should be reordering anything
