First build the gem

gem build toy_robot_simulator.gemspec

Next install the gem

gem install toy_robot_simulator-0.0.0.gem

The gem should now be installed, and the toy_robot_simulator command should be available.

The toy_robot_simulator command will be availabel if you have installed the gem. It reads instructions from STDIN.

I have included some examples in the example directory.

This is how (for example) you would run example "a":

cat examples/example_a | toy_robot_simulator
