Question

I have a variadic D-style function foo(format, ...), which is a wrapper around writefln. I’d like to do something like this:

foo(format, <...>) {
    //...
    writefln(format, ...);
}

Essentially, passing on the ellipsis parameter(s) to writefln. I understand that this isn’t easy/possible in C/C++, but is there a way to accomplish this in D?

This will do it for you:

import std.stdio;
void customWrite(Args...)(string format, Args args)
{
    writefln(format, args);
}
