testing ruby: 1.9.3; Capistrano: > 2.0

capistrano-colorized-stream adds a feature to append colorized hostnames at the head of each line for the capistrano's stream method.

With this gem, it enables you to watch logs on multiple deploying hosts concurrently with colored hostnames like foreman, for example.

For example, to stream /var/log/syslog files located on multiple hosts, use the extended stream method at config/deploy.rb as:

require 'capistrano/colorized_stream'

server host1, :web
server host2, :web

task :syslog, :roles => :web do
  stream "tail -f /var/log/syslog"
end

Then, execute the defined capistrano task

$ bundle exec cap syslog

Below is an example of results.
