For any who has seen my posts on other OSX text editors such as TextMate and MacVim but were unhappy and were looking something with a little more power, extensibility and features, than Aquamacs, the Cocoa port of Emacs is likely for you. Emacs over years (first released and still developed by Richard Stallman since 1976) has built-in many, many features, however some people don’t like that and prefer the quickness of Vim. I myself like to get as much of something as I can get, no matter how much effort and it takes, and Emacs gives me more than Vim can. Another plus for Emacs is that at its core is a powerful implementation of its own Lisp version allowing the initiated to achieve even more power than what something like Vim Script can right now.
Aquamacs gives you all the power of Emacs while giving the beauty of Cocoa allowing Aquamacs to fit right into OSX. Try it out for yourself here.
