Create UUIDs and copy the resulting string into your header and source code file
UUID Generator is a free and simple Mac OS X application for generating UUIDs. It allows you to simply Create UUIDs and copy the resulting String into your header and source code files.
While Mac OS X (I believe as of v10.1) includes the command line uuidgen tool, the advantage of UUID Generator is that its a GUI tool, is available as a Service, and outputs the UUID in various formats: as a hyphen-punctuated ASCII string, as the individual bytes, or in a format suitable for use as a #define for a CMPlugInFactoryID. The output is also sent to the applications GUI, to stdout, and/or to the Clipboard. The formats and output Locations are configurable via application preferences.
There are further advantages as of UUID Generator 1.1. UUID generation can now be performed by various algorithms: the Apple CFUUID, or the e2fsprogs algorithms, which allow generation by time/Ethernet MAC address or a Pure random number. UUID Generator is now a Universal Binary. Offers a cmd-shift-U shortcut to make it even easier to use UUID Generator as a Service within your favorite text editor. And for those that really want a command-line tool, I have created huuidgen which gives you all The Power of UUID Generator within a simple drop-in replacement for uuidgen (even the Linux versions with -r|-t switches), and the convenience of a command line tool you can free download UUID Generator 1.1 now.
