half-assed attempt at rewriting dm-gen to use Thor

gistfile1.rb

require 'thor'
require 'thor/actions'

module DataMapper
  module Gen
    class CLI < Thor

      include Thor::Actions

      DM_VERSION = '1.0'

      desc "one_file NAME [MODEL]", %{
        Generates a 'one file test' for DataMapper, including debug logging and sqlite3 memory DB
        Use like 'dm-gen one_file filename [model] [model,attributes,here]'

        For example:
            dm-gen one_file validation_test Post title:string,body:text

          generates a one file test called 'validation_test.rb' which will have a class
          called Post in it, with 3 properties: a Serial id (added for free), and a title
          and a body.

      def one_file(name,model='test_model')

        @file_name = name.sub(/\.rb\z/,'')
        @properties = {}

        options.attributes.each do |key,value|
          # skip if the property is named id
          next if key == 'id'

          # convert to snake/camel case
          @properties[underscore(key)] = camelcase(value)
