Connect to Heroku RedisCloud as `redis-cli`

redis_cloud_heroku_cli.rb

#!/usr/bin/env ruby
url_matcher = %r{REDISCLOUD_URL:\s*redis://rediscloud:(\w+)@([\w\-.]+):(\d+)}
env_string = `heroku config | grep REDISCLOUD_URL`

env_settings = env_string.split('\n')

match_data = url_matcher.match(env_settings[0])

db = ARGV[0] || 0

command = %{redis-cli -h #{match_data[2]} -p #{match_data[3]} -a #{match_data[1]} -n #{db}}
system command

Thanks! Also, heroku config:get REDISCLOUD_URL returns just the URL. So I compacted a bit:

url_matcher = %r{redis://rediscloud:(\w+)@([\w\-.]+):(\d+)}
match_data = url_matcher.match(`heroku config:get REDISCLOUD_URL`)
