Uuid formating with dashes [message #25117]

I need to have my Uuids formated with dashes in the standard positions.

So I added to Uuid.h as a counterpart to Format:

String UuidFormatDashes(const Uuid& id);

and Uuid.cpp:

String UuidFormatDashes(const Uuid& id) {
	return Sprintf("%08X-%04X-%04X-%04X-%04X%08X", id.a, (id.b & 0xFFFF0000) >> 16, id.b & 0x0000FFFF,
		(id.c & 0xFFFF0000) >> 16, id.c & 0x0000FFFF, id.d);
}

Alternatively, and even probably better this method should be part of Uuid class and drop the prefix.

Useful.

Added as FormatWithDashes.

Thank you!

I added the "Uuid" prefix so that I don't take up a general name as "FormatDashes", which can theoretically be applied to anything. Function overloading should fix that though.

I might have to update the scan part too.

I think that is the point - next time we can use the same 'FormatWithDashes' for any other type. While perhaps not that important in this case, this strategy pays off with templates... Smile
