In this howto we install Mumble-Ruby into a new users´ context.

We use a Debian 'Wheezy' (stable), Ubuntu should work, too. Even Debian Squeeze (oldstable) does the job, if you install libopus0 and libopus-dev from the backports.

Install the following dependencies as root or via sudo:

apt-get install curl libyaml-dev git libopus-dev build-essential zlib1g zlib1g-dev libssl-dev

As root or via sudo:

adduser botmaster

All relevant scripts will run with this user context.

From now on work as the new user:

su - botmaster

Thanks to [http://rvm.io RVM] (Ruby Version Manager) this howto runs on a Debian, regardless of the Ruby version.

Install the GPG key of rvm:

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

We need at least Ruby 1.9.x, here we use the latest stable version:

curl -L https://get.rvm.io | bash -s stable

    Adding rvm PATH line to /home/botmaster/.profile /home/botmaster/.bashrc /home/botmaster/.zshrc.
    Adding rvm loading line to /home/botmaster/.bash_profile /home/botmaster/.zlogin.
Installation of RVM in /home/botmaster/.rvm/ is almost complete:

  * To start using RVM you need to run `source /home/botmaster/.rvm/scripts/rvm`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

# botmaster,
#
#   Thank you for using RVM!
#   We sincerely hope that RVM helps to make your life easier and more enjoyable!!!

Now your Mumble-Ruby is operational :)

This is essential so that the correct environment is used for the bots. Execute both lines or add them to your start script:

  source ~/.rvm/scripts/rvm
  rvm use @bots

Now download a test Ruby script, to test Mumble-Ruby; the script connects the bot to a server and shows a list of all channels on that server in your console.

wget https://github.com/Natenom/mumble-ruby-related/raw/master/scripts/mumble-ruby-test.rb -O /home/botmaster/mumble-ruby-test.rb

See the script here.

Now run the script:

ruby mumble-ruby-test.rb
