My Annotated Vimrc

I am obsessed with Vim. Folks who’ve programmed with me, or attended the Vim Chicago Meetup when I was an active organizer, can attest. Vim is part of my developer origin story and it’s part of my identity as a developer. Any skill I have as a programmer started with gaining competence in Vim.

Should you learn Vim? I think so. I hope to make that case in an upcoming post.

A Vim developer is only as good as their Vim configuration file, their .vimrc1. In that spirit, here is my personal .vimrc with annotations.

My Vimrc

My .vimrc is broken up into three groups: settings, mappings, and filetype-specific settings. If you open this file in Vim, you’ll see why: it’s long, and it’s folded up by groups as a default. This is one of many tips I picked up reading Learn VimScript The Hard Way by Steve Losh, and the dotfiles of programmers I admire.

What have I missed? What could I be doing better? I welcome pull request on my dotfiles repo. Even if I don’t merge the changes, we’ll both learn something.

Interested in copying this file on your root directory, along with the rest of my dotfiles? That’s not a bad a idea. Alternatively, you could build your own from scratch. You’ll learn more about what you value as a developer in that simple exercise than you’ll learn from a thousand Vim blog posts like this one. Good luck!


I posted this on Reddit and got a lot of attention! Some smart folks helped me improve my workflow; the .vimrc shown here reflects some of their suggestions. I want to give credit to folks who took the time to contribute, and also direct future feedback (which I still welcome) to settings that I’m currently using.

  1. Ever wondered what rc stands for? Here’s my answer.
