This gem allows you to use your blink1 from thingm along with guard to show if your tests are failing (red) or passing (green)

After reading this guard-dev post I decided to use the resultant Guard File notification born out of that very discussion.

You need guard & guard-shell

so if you haven't already, add

gem 'guard'
gem 'guard-shell'

to your Gemfile

and also add

gem 'guard-blink1' after this

you'll probably want to put them in your development group

group :development do
  gem 'guard'
  gem 'guard-shell'
  gem 'guard-blink1'
end

NB.\ putting them in the test group will cause issues on machines without libusb installed. e.g/ Continuous Integration Servers

notification(:file, path: '.guard_result')

require 'guard_blink1'
guard :shell do
  watch '.guard_result' do
    firstline =  File.read('.guard_result').lines.first.strip
    GuardBlink1.blink_colour(firstline)
  end
end

As we're using an intermediary file called .guard_result you'll probably want to add that to your .gitignore file, so you won't commit it to git.

Now get back to coding with your blink1 as your Red/Green testing buddy :)

Here's an example Vine I made earlier https://vine.co/v/bEjJD3UerFt for all you people from the future! :)

Many thanks to:

• amiel and his gist which gave me inspiration to create this gem.
• ngs for creating the wonderful blink1 ruby gem, rb-blink1
• All the Ruby guys & gals around the world :)
