Add a string copy function

Description

Probably I really missed it.

I cannot find a copy function. Basically I want to make this

char[200] buf;
char[] res = Layout.sprint( buf, "{}", getString());
// res is a slice of buf.

So probably text.Util would be a good place for it?

T[] stringcopy(T)( T[] buf, T[] src ){
    if( buf.length < src.length ){
        buf[] = src[0 .. buf.length ];
        return buf;
    }
    else{
        buf[ 0 .. src.length ] = src[];
        return buf[ 0 .. src.length ];
    }
}

Not quite sure what you're asking for, Frank? Layout.sprint() already operates as you illustrate

I am asking for this stringcopy function, without the need to go over the layout object/method with a format string.

Hrm, I thought array syntax was supposed to take care of that directly? I guess one could be added to the Array templates, if Sean thinks that's appropriate?

The array syntax does take care of this. You can do "a[] = b[]" or define ranges to copy or whatever. Is a function really needed?

Yes, but

But essentially you want memcpy?

05/24/08 22:01:06 changed by keinfarbton

no, i am asking for a copy funtion that does restrict the copy-length to the supplied buffer.

05/24/08 23:05:57 changed by larsivi

Hmm, ok, and I guess we've established that array copy doesn't currently do this. The change in the runtime would be simple, but I don't know if the spec would allow it (although I see no real reason to disallow it).
