I'm a long time Emacs user, but partially switched to MacVim 2 years ago, and have been using it for all my programming work (still using Emacs for other stuff). I decided to switch back to Emacs now, mainly because of the awesome evil-mode. I'm quite happy, but I still haven't found something as good and simple as the Vim Command-T plugin.
The main problem with the Emacs alternatives is that they are either too complicated and or slow.
The closest thing to Command-T is helm/helm-cmd-t, but it doesn't quite work like it.
Let's say you have two paths:
app/controllers/admin/feedback_controller.rbapp/controllers/fee_controller.rbIn Vim's Command-T, you can write:
app/controllers/fe
And it will match both paths.
With helm-cmd-t, if I write app/controllers/fee, it will only match fee_controller. If I want to match both, I have to use a regexp, as in app/controllers/.*, which is not that bad, but requires more keystrokes.
Any suggestions appreciated!
Long story short - there's nothing quite like command-T for Emacs. Best options are gpicker or Peepcode's peepopen, but they are external applications, and I find them to be distracting after using command-T for so long. I'll stick to MacVim for now, only because of command-T, but might look into implementing something that behaves just like command-T as an exercise.
Thank you all for the answers and comments!
