Hi,

I'd like to know if there's a D way to format a char[] the way printf does?

Thanks,
Nils

import std.string;
import std.stdio;

void main()
{
int x=10;
real y = 1.0/17;
char [] s = format("x=", x, "y = %.8f", y);
writefln(s);
}

std.string.format does this very well:

import std.string;

void somefunc()
{
    char[] aString = format( "String! %d%f%s", 10, 10.0f, "foo" );

    //The D style use is also supported:

    char[] bString = format( "String! ", 10, 10.0f, "foo" );

    //aString and bString are equal...
}

There's also sformat for a sprintf style call where you pass a char[] buffer as the first argument

Thanks a lot! It's not yet part of Skys docwiki so I missed that one :[
Guess I have to look up the original docs more often.
