README.md

This patch to guard is required: https://github.com/amiel/guard/commit/7d25f11a21400e836bb30736b814d4f2f7cebe2dif

UPDATE: This has been merged to guard master.

Put this in your Gemfile:

# The changes required are here: https://github.com/guard/guard/pull/407
gem 'guard', git: 'https://github.com/guard/guard.git'

Install digiusb. (I don't have it in my Gemfile because it's not really a project dependency...)

gem install digiusb

Put digicolor.rb somewher inis in your PATH (don't forget to chmod +x).

digicolor.rb

#!/usr/bin/env ruby -rubygems

require 'digiusb/digiblink'

# TODO:
COLORS = {
  'success' => 'green',
  'failed'  => 'red',
  'pending' => '#ff5500',
  'off'     => 'black',
  'default' => 'black',
}

def get_spark
  @spark ||= DigiBlink.sparks.last
end

def set_color(color)
  get_spark.color = color
# rescue LIBUSB::ERROR_NO_DEVICE
#   @light = nil
end

color = COLORS.fetch(ARGV[0]) do |key|
  begin
    key.to_color; key
  rescue ArgumentError, NoMethodError
    COLORS['default']
  end
end

puts "DIGIRGB: #{color}"

if ARGV[1] == '--blink'
  set_color('black')
  sleep 1
end

set_color(color)

guard.rb

notification(:file, path: '.guard_result')
guard(:shell) do
  watch('.guard_result') do
    ::Bundler.with_clean_env do
      `digicolor $(head -1 .guard_result) --blink`
    end
  end
end

Thanks @amiel, you gave me inspiration to create this Gem for the blink1 - https://github.com/GeoffTidey/guard-blink1
