Overview

This is a rough spec for a gem I would like to use to connect to X.commerce. As X.commerce is new and my experience with it is limited, I'd like to discuss with the community first how best to structure the interaction before actual code is written.

Structure

I've spec'd out the following basic object structure:

jszmajda

def points(x)
  {
    1 => 1,
    2 => 2,
    3 => 5,
    4 => 7,
    6 => 15,
    8 => 21
  }[x.to_i]
end

      own = options[:owner]
      stories = options[:stories]

      stories.split(/\n/).each do |story|
        md = story.strip.match(/^([fcb])(\d) (.*?) \[(.*)\]$/)
