How to create dynamic menulets in OSX

Question

I want to put a dynamically generated icon (not static image) + possibly a tiny bit of text in OSX menu bar.

If possible I'd prefer to do it from Ruby or some other convenient scripting language, but I'll deal with Objective C if that's the only way.

How do I do that?

Answer 1

Have a look at MacRuby: virtually everything you can do from Obj-C you can also do from MacRuby.

As for details, look for an Obj-C tutorial, and work from that.

Oh, and the term you will need to use is NSStatusItem.
