First, a little oddity I noticed while messing around in Interface Builder today. If you add an NSTextFieldCell to a table column and try to change it’s class you’ll notice that it doesn’t list NSTokenFieldCell. If you want to have a token cell in your table you have to add the NSTokenFieldCell header from AppKit into IB. Why it isn’t already in IB I don’t know, but it’s worth pointing out.

And now onto something a bit more exciting. I’ve spent the day working on our next application and hit a snag when I wanted to build a rule editor, similar to those used in Mail and iTunes for smart Mailboxes/Playlists. After spending a few hours trying to write something I gave up and decided to look for sample code on the interweb. After much searching I found that there wasn’t really any code that did what I want, things were looking glum. Then I stumbled across this code and suddenly the sun came out (thanks a lot to Joar for this code). Several hours later and I had a working rule editor. All that was left to do was package it up, update our Open Source site and write a blog post (*checks writing blog post off his list*).

So here it is, M3RuleEditor. Feel free to download it, use it, hack it, put it in your apps, make soup from it…. whatever takes your fancy. And keep a look out for this code appearing in a new M Cubed app coming soon
