Let's say you're looking to make some new friends. There are lots of dating sites out there that claim to match you based on advanced metrics and algorithms.
But we're programmers. We don't need all that. Instead we can just comb git logs to find the people we likely share interests with!
The log of any git repo has the names and email addresses of of people who have contributed. Write a program that can generate a list of those people.
From your terminal:
$ ruby ./okcugit.rb turingschool/challenges
"Jeff Casimir" <[email protected]>,
"Rachel Warbelow" <[email protected]>
The output should be alphabetized by the first character of the name. An name/email pair should not appear more than once.
require_relative 'finder'
repo_name = ARGV[0]
finder = OkCuGit::Finder.new(repo_name)
contacts = finder.all_contributors
puts contacts.join("\n")
To interact with git you'll likely need to use some "shell" commands from within your ruby script. Here are a couple that may be useful for you:
- Any commands within backticks in a ruby file will be run as system commands:
current_dir = `pwd` #use pwd command to get current directory
puts current_dirWe can use this to interact with git from our ruby programs. For example:
git clone https://github.com/turingschool/challenges.gitDir.chdiris a method in ruby for changing the current working directory on the system. (equivalent to runningcdfrom the command line):
Dir.chdir("/tmp")You will likely want to use this method to change into your
newly cloned directories so you can run git log.
Don't forget you can return to the previous (parent) directory with:
Dir.chdir("..")- Write the results to a text file in ascending order by last name
- Write the results to a CSV file.
