I use Emacs, and I have been an Emacs user for at least 16 years. I think it is the most productive tool I have ever used, and not only for software development activities. Since you are already browsing this site, I won’t bore you with the reasons I think this way.
I wrote wdired, that since year 2000 is part of Emacs. I also wrote dired-efap and occur-x. Both of them are available via MELPA and Marmalade.
If you are curious, you may find my emacs configuration file here.
