Hi,everyone,
for example:
import std.stdio;
import std.process:executeShell;
extern(C) int setlocale(int,char*);
static this()
{
import core.stdc.wchar_;
import core.stdc.stdio;
fwide(core.stdc.stdio.stdout,1);
setlocale(0,cast(char*)"china");
}
void main()

std.conv.to will allow you to convert between string and
wstring, but for calling C functions, you still need the
strings to be zero-terminated unless the functio

You define a function implementing the "less" operation for a pair of
Tuple!(Address, int) (or whatever you have).

I looked at this a while ago for similar reasons. It didn't pan out.

Sorry about that.
The issue is that Address doesn't have a comparison operator
defined, so the resulting tuple type can't be compared with the

Have you considered 'alias this'?

Thanks!

As always, it helps a lot to post the error message the compiler gave you.
The message is:

Can anyone please explain to me what's going on here?

Hi,
I'm trying to check whether it's possible to implement Python's
SQLAlchemy-like query syntax in D, but I get stuck a bit.
Here is a simple example of what I want to achieve:
```
auto result = User.filter(User.id == 10);
result = User.filter(User.name == "John");
result = User.filter(User.

Is there a possibility to create a recursive structure with a
tagged pointer? As this does not compile, even without tagging
bits.
