Developing a Slack app in Ruby? This gem will make your life a bit easier.
SlackWidgets will remove the need to write JSON to create Slack buttons and other widgets.

Add this line to your application's Gemfile:

gem 'slack_widgets'

And then execute:

$ bundle

Or install it yourself as:

$ gem install slack_widgets

SlackWidgets::PrimaryButton.create(name: 'continue_button', text: 'Continue', value: 'continue')

# => {:name=>"continue_button",
#     :text=>"Continue",
#     :type=>"button",
#     :style=>"primary",
#     :value=>"continue"}
# This is exactly the format Slack expects in order to create
# a nice green (approval) button with the text "Continue" on it

Primary and Danger button examples:

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.
