1. This matrix is purely based on commits.
2. Darker the line more the pair has worked together.
3. If you see a dark red circle around a name that means the person has worked alone

Add this line to your application's Gemfile:

gem 'pairing_matrix'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pairing_matrix

First of all you need to decide a format for your commit messages e.g. #Feature [Dev1/Dev2] Your commit message

You can choose any format as long as you are able to extract dev names from the message using a regex. Once you have decided on the commit message format, create a pairing_matrix.yml file.

authors_regex: ^.*\[([\w]*)(?:\/)?([\w]*)\].*$

github:
  url: https://api.github.com/
  access_token: 000324cgf89weq56132f32c345hn679c0knh501c
  repositories:
    - org1/repo1
    - org1/repo2
    - github_username/my_private_repo

This regex is used to extract dev names from the commit message. You can verify your regex in irb console using the below command. If your regex is correct it will return an array of dev names.

e.g

"#4324 [Ajit/Abhishek] My commit message".scan(/^.*\[([\w]*)(?:\/)?([\w]*)\].*$/).flatten
=> ["Ajit", "Abhishek"]

If you want to use private repos for matrix, then create a access token and give it the repo read permission. Here is how you can create the token:

Github: https://help.github.com/articles/creating-a-personal-access-token-for-the-command-line/

Gitlab: https://docs.gitlab.com/ee/user/profile/personal_access_tokens.html

List your repos which you want to use for matrix. If you have your repos inside organization then follow the org/repo format else just mention username/repo.

Now after installing the pairing matrix gem, simply run the pairing_matrix command in the repo where you have pairing_matrix.yml file. This command will start a web server. Then hit the url localhost:4567/matrix or localhost:4567 in the browser. In case you want to use the json data, hit http://localhost:4567/data/:days

Pairing matrix gem supports below platforms:

• Github
• Gitlab
• Local

Support for bitbucket is coming soon!
