Programming Rule Number 0 - Never, Ever Work too Hard
Jun 8, 2020
One of the better lessons that you learn as a programmer is that you never want to work too large, in short, that laziness can be a virtue. I'm speaking, of course, of doing things manually that you can automate. I recently wanted to download a set of images from github that represented anonymous animals. Here's the repo:
[https://github.com/wayou/anonymous-animals/tree/master/icons](https://github.com/wayou/anonymous-animals/tree/master/icons)
What I needed to automate downloading these was two things:
- A set of filenames
- A means to iterate them and fetch the data
The set of filenames I got just by copying text from the github page and using a text editor macro to reduce it to a set of filenames that %w could easily make into an array. Here's the code for that:
def self.animals
anims = %w(
Alligator.png
Anteater.png
Armadillo.png
Auroch.png
Axolotl.png
Badger.png)
end
My routine to download these looks like this:
def self.wgets
AnonAnimalCommon.animals.each do |animal|
`cd /Users/sjohnson/Sync/coding/rails/wipmarks/app/assets/images && wget wget https://raw.githubusercontent.com/wayou/anonymous-animals/master/icons/#{animal}`
end
end
My final step was to call this routine from the Rails console (the entire class is called AnonAnimal):
AnonAnimal.wgets
Downloading all of these manually would have been likely about a half hour. Writing this code took maybe 10 minutes. Laziness for the win!
