I used to love TextMate, but changed to Vim after finally giving it a chance. I m somewhat amused that ViMate exists. However, in my experience, vi input modes are kinda hit-and-miss. (Example: viper mode in emacs. It s close, but not enough to make me start to use emacs. Also, the system-wide keybindings for OS X.) I ll be interested to see how it turns out.

If what you re looking for is a "Mac integrated Vim" through TextMate, you might try MacVim too. It s the real Vim, but it has Mac keybindings and looks prettier. :) (It s like gvim, but written in Cocoa, I believe.)

You can use ViMate.

Try VicoApp. It s similar to textmate and has support many Vim key-bindings.
