Code Walk

A simple utility to help keep students focused on the right output during code walks.

Usage:

$ codewalk ruby examples.rb

Or...

$ codewalk node examples.js 10 50

codewalk will run the specified command in a subshell and split the output into chunks separated by the regex /\nEXAMPLE [0-9]*\n/ or similar, then output only the most recent chunk.

It's useful to define a function such as...

def example num
    puts
    puts "EXAMPLE #{num}"
    puts
end

... at the top of your file so it is easy to separate examples, produces more readable source, and will still run as a normal script with pretty output of all examples when students who don't have the codewalk gem installed run the finished examples script.
