Are you the next (Ruby) Thanos?

daviducolo profile image Davide Santangelo ・2 min read

for fun, I asked myself:

Is there a way to know who is the best Ruby gem maker on the planet? Who is entitled to the title of "Gemminator"?

so I decided to write a Ruby script to take some information and get a score.

Score

The score GS ( Gemminator Score ) is defined by the sum of two values. The RGS (RubyGems Score) and GHS (GitHub Score).

RGS

sum(downloads) + (1.0 - 1.0/count(gems))
Enter fullscreen mode Exit fullscreen mode

GHS

sum(stars + forks) + (1.0 - 1.0/count(repositories))
Enter fullscreen mode Exit fullscreen mode

GS

GS = RGS + GHS 
Enter fullscreen mode Exit fullscreen mode

OK! Let's start writing some code!

Gems

for data collection I use two gems that are:

Gems - Ruby wrapper for the RubyGems.org API https://rubygems.org
Octokit - Ruby toolkit for the GitHub API http://octokit.github.io/octokit.rb/

Script

you need a GitHub personal access token to avoid rate limit. A personal access token is a token you have generated (https://github.com/settings/tokens) that can be used to access the GitHub API.

  require 'octokit'
  require 'gems'

  downloads_count = 0
  stars_count = 0
  forks_count = 0

  client = Octokit::Client.new(access_token: ARGV[1])
  gems = Gems.gems(ARGV[0])

  downloads = gems.map do |gem| 
    gem['downloads']
  end
Enter fullscreen mode Exit fullscreen mode

fetch counters

downloads_count = downloads.sum

gems.select! do |gem| 
  gem['homepage_uri'].to_s.start_with? 'https://github.com'
end

github_repos = gems.map do |gem|
  client.repo(gem['homepage_uri'].split("/").last(2).join("/")) rescue nil
end.compact

github_repos.map do |repo|
  stars_count += repo.stargazers_count
  forks_count += repo.forks
end

Enter fullscreen mode Exit fullscreen mode

get results

rgs = downloads_count + (1.0 - 1.0 / gems.size)
ghs = stars_count + forks_count + (1.0 - 1.0 / github_repos.size)

gs = rgs + ghs
Enter fullscreen mode Exit fullscreen mode

Examples

ruby gemminator.rb <rubygem_username> <github_access_token>
Enter fullscreen mode Exit fullscreen mode

https://rubygems.org/profiles/davidesantangelo

➜ ruby gemminator.rb davidesantangelo <token>
110751.675
Enter fullscreen mode Exit fullscreen mode

https://rubygems.org/profiles/ankane

➜ ruby gemminator.rb ankane <token>
43355989.97872341
Enter fullscreen mode Exit fullscreen mode

https://rubygems.org/profiles/sferik

➜ ruby gemminator.rb sferik <token>
1519272118.937439
Enter fullscreen mode Exit fullscreen mode

Note

of course, it is a basic demo script without the management of all the exceptions/optimizations that can be found.

It should have some weightage on if gem is maintained or not, probably based on recent pr or commits.

Of course! Thanks for the feedback. Obviously as explained it is a script written in a short time that does not take into account various factors, but thanks I'll keep it in mind.
