title: There is an Evil in your Emacs

When I first started using GNU/Linux I was looking for a proper text
editor. I only had any experience with Visual Studio on Windows
because I was a .Net developer at the time, and didn't really have
much of a choice. One of the main things I wanted was an editor that
worked in a terminal.
Naturally I came to Vim and Emacs (as well as Nano, and perhaps some
others as well). For a few weeks I kept switching between Vim and
Emacs. I liked Vim's syntax highlighting better, but on the other hand
I liked Emacs' keybindings/modelessness better as well. I ended up
going with Emacs mostly because of Vim's moded editing.
For years the thought of Vim's moded editing gave me nightmares. I
never really realised the best thing about Vim. Even when a post
appears on Stack Overflow about grokking Vim. I was already so blinded
by the idea that Emacs was the superior editor for me that I failed to
register the information. It took a long time, but eventually I opened
up to the possibility of such moded editing. By now I was stuck with
Emacs because I just couldn't give up its customizability or
extensibility. Also, I've grown to love Lisp, and specifically Emacs
Lisp, so to go from that to Vimscript wouldn't be quite ideal.
Eventually I decided I really did want to try it. Thankfully Emacs has
a package for that: Evil, the Extensible Vi Layer for Emacs. There is
one other problem, though: I use the Colemak keyboard layout. The
usual `hjkl` keys are more like `hynu`, with the up key at the bottom
of the keyboard, down at the top and left and right diagonally from
eachother. Again Emacs has a package for that, `colemak-evil`. It
rebinds some of the keys so that Evil will work with the Colemak
keyboard layout. It is based on that the creator of the Colemak layout
used to use in Vim. It's a bit aggressive, so I customized it to be a
little less so, mostly removing rebindigs from the motion and emacs
state maps.
The real power is in the composability of the commands. In Emacs you
have commands like `forward-kill-word`, `forward-kill-sexp` and
`forward-kill-char`. In Vim you have the `delete` operation, which can
be combined with, for example, the `forward-word` motion, or the
`next-line` or `forward-char` motion. I probably have the names wrong,
but hopefully they convey the meaning of what they do. This is what it
is all about, or at least from what I've learned to use so far. Of
course the powerful ed-like editing features called forth through the
Vim `ex` mode, such as `%s/find/replace`. Lastly, of course, the fact
that a lot of editing can be done in normal mode helps in preventing
Emacs-pinky.
I haven't yet been able to work with the extensible part, but some of
the modules that exist for evil speak volumes of it.
If you are interested in increasing your productivity, or you like to
experiment with new things, you might really want to try it. It may
not completely be Vim, but it's still completely Emacs. If you use the
colemak-evil package as well you'll also notice that in the insert
state all your regular Emacs keys work normally, which is a great
combination of the two editors. So far I feel that Vim is great for
editing existing code and text, but Emacs still feels better when
writing a lot of new code or text.
