a langfeldian binary encoding tool

enlang.rb

#! /usr/bin/ruby

# full of sound and fury
class Hippie
  def initialize(name)
    @name = name
  end

  def smoke(this)
    ciphertext = encode(this)
    key = enkey(this)
    [ciphertext, nil, '---', nil, key].join("\n")
  end

  private

  def encode(that)
    that.split(/(?<=\s)/).map { |row| asciify(row) }.join("\n")
  end

  def asciify(row)
    row.each_byte.map { |byte| binarize(byte) }.join(' ')
  end

  def binarize(byte)
    '%08b' % byte
  end

  def describe(byte)
    case byte.chr
    when ' '
      'space'
    when '.'
      'period'
    else
      byte.chr
    end
  end

  def key_row(byte)
    "#{describe byte}:\t#{binarize byte}"
  end

  def enkey(that)
    that.bytes.uniq.shuffle.map { |byte| key_row byte }.join("\n")
  end
end

langfeld = Hippie.new('john')
puts langfeld.smoke('The Evil Queen.')

the sneaky part is not excluding the spaces, accomplished here via a regular expression lookback .split(/(?<=\s)/)
