Those of you who hack on Gecko code will know that when changing an XPCOM interface, you need to update the IID. Now, in the dim fog of morning, when I haven't drunk enough coffee, how on earth am I supposed to remember that the command-line utility for UUID GENeration is named uuidgen? I wish these things had useful mnemonics!
Yes, I could pop in to irc.mozilla.org, and ask firebot. However, I would inevitably forget to /msg firebot, and it is well known that #developers is a hotbed of nefarious sorts, lying in wait to snatch your newly-minted IID and ride off into the sunset, cackling with glee. I could navigate to one of the many online tools, but, sheesh, that sure sounds like a lot of work, you know?
mach to the rescue. I've landed a mach uuid command, which will furnish you with a UUID in canonical form. Alternatively, use mach uuid -f cpp for the C++ form.
Happy IID revving!
