digitalmars.D - swritef()

I've copied and pasted this little snippet so much now that I thought 
I'd post it:

char[] swritef(...)
{
     char[] result;

	void putc(dchar c)
	{
         char[4] buf;
         char[] b;

         b = std.utf.toUTF8(buf, c);
         for (size_t i = 0; i < b.length; i++) {
             result ~= b[i];
	    }
	}

	std.format.doFormat(&putc, _arguments, _argptr);

     return result;
}

Dunno if it's very efficient or anything, but I think such a thing is 
really needed, and as far as I can tell, phobos doesn't contain it yet.

How bout this ?


char[] str(...)  // or call it swritef; this name's from Python
{
	char[] result;

	void putc(dchar c)
	{
		std.utf.encode(result, c);
	}

	std.format.doFormat(&putc, _arguments, _argptr);
	return result;
}

You're right, I overlooked the encode() function. Thanks :)

Not only that, but it's identic to what h3r3tic posted...

This should be in the docs! ;)

I still prefer the name swritef, though.

Wow, I've just reinvented the wheel :D
I'll have to patent it <g>

Definitely...

As for std.string.format ... It's quite scary... Say I want to make a 
string with the drive letter in it. Shall I do it with 'format("C:")' ? ;)

I added a small section in the documentation amendments in Wiki4d.
