tombooth/bob-walker

Alternative to vcloud-walker

bob-walker

An alternative to alphagov/vcloud-walker in various languages.

Background

While this might look like some kind of internet bullying, it's all in good fun and mostly sanctioned by the real namesake.

Our team happens to have a Ruby project which walks through the API of a VMWare vCloud instance showing the various objects, which is called vcloud-walker. By happy coincidence, one of our team is called bob walker. It was funny to knock up a quick bob-walker implementation in shell one day, but this project has grown into a place where our team can create educational, clever or funny implementations of the original shell script in our own time.
