with_status

Use with_status to run commands and have your arduino let you know when they are done.

with_status starts by turning the LED off before running your command. Once your command completes, it will turn the LED on. Green if the command succeeded, and red if it failed.

I use this with long running commands (such as deploying to heroku), so I can start working on something else without forgetting about my process.

INSTALL

Copy both digicolor and with_status (without extension) to somewhere in your PATH and don't forget to chmod +x them.

USAGE

Simple example:

with_status "ls" # green
with_status "ls this/does/not/exist" # red

Rails (because rails is slow sometimes):

with_status rake routes
with_status rake -T
with_status bundle

Heroku processes:

with_status heroku db:pull

with_status "heroku maintenance:on && git push heroku master && heroku run rake db:migrate && heroku restart && heroku maintenance:off"

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
  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)

with_status.sh

#!/bin/bash

digicolor black

if eval "$@";then
  digicolor success
else
  digicolor failed
fi

I love it, one small adjustment I had to do to with_status.sh was to add "source ~/.zshrc" otherwise my aliases weren't being included.
