My configuration repositories #

Do not expect extremely polished dotfiles. I know some of you will be pulling your hair out with some of the stuff you see here:

I will not give you counsel, saying do this, or do that. For not in doing or contriving, nor in choosing between this course and another, can I avail; but only in knowing what was and is, and in part also what shall be.


I’ve been a Neovim user and fan for a bit more than a year now. After having given it a reasonable spin I’ve become quite efficient at working with it, and it’s been a pleasure all the way through. Certainly, I’m a lot faster with my Tmux/Neovim/gitsh workspace than I was with either Atom, Sublime Text or VSCode, and I feel a lot more comfortable.

From this point and forward, and although I use Neovim, I’ll be using the words Vim and Neovim interchangeably. Whether I refer to the software packages or to a specific user community should be clear in context.

During the last weeks I’ve noticed several tools and concepts in the Emacs which I’ve found attractive enough to try out the platform. These include:

So I decided to surrender to my sacrilegous self and try to emulate everything I do with Vim from an empty Emacs config file built with Org-mode. And I must say: it’s been a breeze! I haven’t even needed to dedicate much time to learning actual Emacs, and what I’ve learned has actually been nice. In this post I’ll try to go through what I did to rebuild my setup; I hope you’ll enjoy it as much as I did.

Package management #

For package management needs the Vim community has contributed several awesome packages like Pathogen or vim-plug among the many worth mentioning. I’ve always used vim-plug and never found a problem with it. As active as the Emacs community is in regards to package development, I expected a solution that would provide the same level of comfort.

Emacs comes bundled with Package, and this is as much as I’m aware of: it takes care of package repository management, and to configure it I only needed to add the links to those repositories and initialize it.

Package, however, does not take responsibility for automatic fetching, updates, and encapsulation of configuration (which vim-plug does, and very well). For this, I’ve found the de-facto solution to be use-package. To be able to work with use-package using its minimal functionality, this is all you need to know:

It didn’t take me too long to learn this, and use-package allegedly does a thousand more things which I’ll begin to learn with time.

Vim things and Evil things #

Evil calls itself the extensible vi layer for Emacs, and claims that it emulates the main features of Vim. I’d say this is an understatement; Evil feels like a complete re-implementation of Vim’s porcelain. It makes you feel right at home once you start using it:

Using evil-leader you can configure a leader key. I’ve configured mine to Space, and added a several keybindings. The same results can be achieved with the more powerful general.el, and if you need chained keystrokes to produce a command (for example, I used to have <leader> wq, which I found faster than :wq), you can use Hydra. I haven’t found a need for these and I’m doing just fine with evil-leader.

Project management and file navigation #

My setup using Vim is basically fzf (which I use for many more things outside Vim) powered by Ag (or The Silver Searcher) for finding files and ripgrep for finding text in a project. This works flawlessly.

I’ve found the combination of Helm and Projectile to be an adequate substitute to my former setup. On big projects like Servo, the difference in speed is noticeable (in favor of the Vim configuration) but I can live with that. I don’t know why, but there’s a longer load time on the Emacs setup.

The scope of fzf is by no means comparable to that of Helm and Projectile, so this is not meant to be a comparison but it does happen to be what covers my file-finding needs. Both setups enable extremely quick fuzzy search for files and content.

As you can see on my Emacs configuration, my setup for Helm and Projectile is extremely basic and I haven’t needed further customization yet. And I must say: they look much prettier than the Vim setup I use.

Specific packages #

A quick search on your favorite engine will yield at least a couple different solutions to problems some of the nicest Vim plugins solve. Here’s a quick list to encourage you:

Regarding Tim Pope plugins: there’s an Emacs port for everything Mr. Pope does. Many of these go on top of Evil, and it’s a no-brainer to add them and use them if you’re used to their Vim counterpart.

Theming #

Themes are really easy to set up on Emacs. Just add a use-package declaration and then load it with (load-theme 'pretty-theme t). The second argument automatically answers “yes” to a couple security questions that pop up every time you load a new theme. Emacs themes can run arbitrary Elisp so they can do a lot of nasty stuff. Make sure you trust the sources where you get your themes.

If I had to complain about anything, I’d say most themes work much better on the GUI version of Emacs, and I use the terminal version (emacs -nw). Many themes’ backgrounds are broken and show up differently depending on your $TERM environment variable. Of the ones I’ve tried, I’ve found Monokai and Badger to work look best on terminal Emacs.

Performance and server mode #

Neovim feels a lot snappier for a lot of interactions. This, however, is not important at all most of the time, because it never shows while writing or navigating text inside a buffer.

The main difference in performance shows in startup time. Here’s a quick-and-dirty comparison using time, with my full configuration loaded on both programs:

time nvim +q
nvim +q  0.13s user 0.02s system 97% cpu 0.160 total
➜  time em +q
emacs -nw +q  2.14s user 0.12s system 44% cpu 5.121 total

Please do not evaluate this as any kind of benchmark: I haven’t done anything to improve startup time on either Neovim or Emacs (like using use-package’s :defer t).

The two seconds of waiting is OK if you open Emacs once and work from there for each project. It is not OK if you’re using Emacs as a default editor for stuff like Git, or even your $EDITOR environment variable.

Emac’s solution to this is server mode. Basically, you start an Emacs server on your fully loaded instance (the one that took two seconds to open). From then on, if you want to open Emacs for a quick edit and you don’t need the default directory to be the one you called Emacs on, you can go emacsclient.

➜  time emacsclient -nw -c -a "" +q
emacsclient -nw -c -a "" +q  0.00s user 0.00s system 0% cpu 3.010 total

Yep - instant! That’s more like it. I have that gravely arcane command (emacsclient -nw -c -a "") set as my $EDITOR environment variable. Also, I have two aliases:

This is admittedly a lot of work compared to just having an editor that loads quickly all the time. But it works! You can see the section of my config file where I set up server mode (basically, there’s no setup).

Conclusion #

Voilà! Now I can continue Vimming around. I can Vim around while writing Lisp comfortably, doing some GTD in Org-mode, using Magit, and having leveled up in snobbism 😭.

Jokes aside, it feels good to have given both editors a chance. I have certainly had a taste of why both communities are so passionate about their preferences. I’ll make another post as soon as I’ve discovered if I can actually use my new setup as fluently as my former configuration. Until then, happy new year!
