Prubot

Prubot is a Ruby Probot (https://github.com/probot/probot) clone. Probot is a framework for building GitHub Apps to automate and improve your workflow.

GitHub has a good comparions of GitHub Actions to GitHub Apps.

Installation

Add this line to your application's Gemfile:

gem 'prubot'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install prubot

Usage

Here is an example of an Welcome Mat:tm: app that comments on opened issues inviting users to join in on discussions:

Make sure you [enable discussions] on any repos you add to this App.

welcomemat.rb

require 'prubot'

on 'issues', 'opened', 'add a welcome message' do
  # `payload` is a hash of the event payload.
  discussions_link = payload['repository']['discussions_url']
  welcome_message = 'Thanks for stopping by :wave:. While we work on getting back to you '\
  "please feel free to check out #{discussions_link}."

  # `issue` extracts information from the event, which can be passed to
  # GitHub API calls (equivalent `pull_request` exists as well). This will return:
  #   { owner: 'yourname', repo: 'yourrepo', number: 123, body: 'Thanks for stopping by...'}
  params = issue({ body: welcome_message })

  # `octokit` provides a hydrated (authenticated as the App installation) octokit.rb client
  # for interacting with GitHub.
  octokit.add_comment(params)
end

To run the Welcome Mat

ruby welcomemat.rb

You should see a link to create a GitHub App.

Welcome to Prubot! Please visit http://localhost:3000 to get started.

Follow that link, and once you've completed the registration you'll be redirected to install the app on repositories. Choose a test repository and then try opening a new issue in that repository!

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
