Emacs with Viper mode: editor nirvana?
I've been a long time Vim user and fan. Once you're used proficient with the Vi way of editing it's difficult go back to anything else. Other editors just feel inefficient and clunky.
That said, I've been jealous of certain Emacs features that I've seen while looking over the shoulders of my colleagues. Multiple frames (GUI windows), the clean extension system (via elisp), the tight process integration (shell, SQL, debuggers etc) and all sorts of unexpected bells and whistles; these goodies slowly ate away at my curiosity.
So 2 weeks ago I caved and decided to give Emacs another go. I hadn't really used it since university. Starting with my colleague's configuration and making some minor tweaks, I began using Emacs for serious work.
A few days in and I was enjoying exploring my new toy but it didn't feel quite right. Although I had a reasonable grasp of Emacs' editing keys and commands, most tasks took way too long, requiring convoluted hand gymnastics. My left pinky was permanently sore from constantly reaching for the Ctrl and Alt keys. I was missing those surgical, efficient Vi commands.
At the suggestion of one Emacs-using colleague I gave Viper (viper-mode) a try. It's an emulation that attempts to provide a fairly accurate Vi experience while still allowing full access to the rest of Emacs. To be honest I was expecting it to be a half-assed kludge. I was wrong. Viper is a mature Emacs extension and it does a great job of mitigating conflicts between the Emacs and Vi ways of doing things.
Viper mode proved to be the tipping point; because of it I'm sticking with Emacs. As far as I'm concerned it's the best of both worlds.
For anyone who's interested, my Emacs config is available in the repository browser here or via bzr. This is my personal configuration branch so it will update as I make changes to the setup. Note that I'm using the latest development (but rock solid) Emacs so there might be references to features in the config which only exist in this version.
Some items of note in my config:
vimpulse: Viper mode only emulates classic Vi. vimpulse provides a bunch of extra features which a Vim user will probably miss such as various "g" commands and visual select mode.
ido-mode: This is a standard feature of Emacs which isn't bound to keys by default. It gives amazing power by replacing the standard find-file and switch-buffer keystrokes with beefed up alternatives. The key features are quick directory switching and fuzzy, recursive name matching (but that's not all).
ibuffer: I've replaced the standard buffer list binding (C-x C-b) with ibuffer. This gives a more powerful and easier to use version of the standard buffer list and allows for crazy batch manipulation of buffers.
yasnippet: Mode specific template expansion. Powerful and super useful for cranking out commonly used sections of text (programming is full of them).
flymake - pyflakes integration: Flymake runs arbitrary programs over buffers on-the-fly. For Python files flymake has been configured to run pyflakes and highlight errors in code as I type. I might change this to use pylint at some stage because pylint finds a wider range of problems.
