Excellent open source code editor for Mac OS X

I found a most excellent code editor for Mac OS X and it’s open source - Smultron! So it’s free - but donations are welcome and it’s very well supported. I’ve used notepad++ for Windows which is great, but never found a good Mac alternative, until now.

Smultron has the basic features like color coding, but for sooo many different syntax definitions than even notepad++ supports. It has many many features I don’t even use, because I’m mostly using it for actionscript, javascript, and tweaking php template files from wordpress. It validates XHTML which is nice, but Dreamweaver already does this as well. Has a nice comment/uncomment command, I use that one a lot. It has a nice highlight current line option, so if the text is wrapping, you can see it highlighting the line below it. The auto complete function is kind of crazy… it never gives me what I’m actually looking for.. so I don’t use it use it much. Instead of having it on by default, you can press option+escape and it will give u the auto complete list. Auto-close tag is another nice feature.
