Getting started with VimGolf
VimGolf is a competitive game that improves your text editing skills. It’s a great way to kill five minutes inbetween tasks and offers the promise of some seriously obscure bragging rights.
If you’re completely unfamiliar with Vim, go try this online tutorial, or at least play Vim Snake or Vim Adventures to get used to the basic movements. What follows will be a quick walkthrough of installing the necessary programs, creating an account, and submitting your first entry.
What you need
To play VimGolf, you must have:
- A Twitter account
If you don’t have Vim installed, please start with this guide to setting up your development environment. You’ll also get
git and Anaconda Python out of the deal.
Installing Ruby might seem like a lot of trouble just to play a game, but the process is pretty painless. In fact, Mac users should already have it installed. To double check, type this into your terminal:
If you see a message about what version of Ruby is installed, you’re good to go.
On Linux, your package manager should handle it for you. If you have Windows, use RubyInstaller.
Finally, VimGolf requires a Twitter account.
Once you have all the requirements in place, it’s time to log in and start playing.
Install and configure VimGolf
Log in with your Twitter account. You should see a black box in the upper right corner of your screen:
Copy the key to your clipboard. Then type the first two commands below it into your terminal. Here’s what they do:
gem install vimgolf
This uses Ruby’s package manager to install the VimGolf program on your machine.
This lets you save your key so the VimGolf program can handle submitting your entries. Here’s what the setup screen looks like:
Paste in your key and you’re ready to go.
Your first round of VimGolf
Now it’s time to browse the site and pick a challenge. I started with this one.
Each challenge consists of “before” and “after” text, and your task is to convert the former into the latter using the fewest possible keystrokes. Luckily you can see other peoples’ submissions, so it’s okay if you’re not sure how to start. Just open up Vim, type or paste in the “before” text, press
<esc> and then type another entry, keystroke for keystroke. Copying other people’s entries is the best way to pick up new Vim tricks and techniques.
As an example, my Vim challenge was to convert
The quick brown fox jumps over the lazy dog.
The quick lazy dog jumps over the brown fox.
The topmost solution on the page looked like this:
So I opened Vim, typed in the “before” text, pressed
<esc> to exit Insert mode and
gg to go to the beginning of the file, then typed
2wd2w3wPd3w6bepZZ. It worked! But how?
It’s useful to break VimGolf solutions up into pieces. Here is a breakdown of the seventeen keystrokes above:
2w – Move forward two words
d2w – Delete two words
3w – Move forward three words
P – Paste/put the previously deleted text before the cursor position
d3w – Delete three words
6b – Move back six words
e – Move to the end of the current word
p – Past/put the previously deleted text after the cursor position
ZZ – Save and quit
After a couple of tries, I understood the solution. However, VimGolf requires you to match or beat the solutions you see. So I came up with my own:
2wd2w3wPd3wFkpZZ. Only 16 keystrokes! The only difference is the use of
Fk (Move backwards to the nearest occurrence of the letter ‘k’) instead of
e. One stroke is all it takes, though.
To submit my answer, I typed the following:
vimgolf put 55bcdc3ef4219f456102374f
I copied the “55bcd…” part from the black box on the VimGolf web page corresponding to the challenge. Here’s what the
vimgolf program looks like in action:
