Subject: Re: Text Munger (#76)

Well, the simple regex based one-liner seems to have gotten
plenty of airplay, so I decided to expand mine in an attempt
to improve the readability of the munged text. For example:

A naive munging:

  Noumeurs idavilundis have dneoatrstmed the ieneascrd
  dfifclutiy oinrcrucg wehn leihngter wdors are slipmy
  reiondmazd. Raionizdnmg wiihtn hntyahoeipn buadoreins
  offers smoe irnmoeemvpt.

A slightly more readable munging:

  Nuemruos inididvuals hvae dnometrtsaed the insecraed
  dfiifulcty ocucrinrg when lghetnier wrods are smiply
  rnamodized. Randomzinig wihtin hyphenatoin bonduiares
  offres some imvoepremnt.

Original text:

  Numerous individuals have demonstrated the increased
  difficulty occurring when lengthier words are simply
  randomized. Randomizing within hyphenation boundaries
  offers some improvement.

The hyphen-boundary randomizer:

  require 'text/hyphen'
  hyp  = Text::Hyphen.new :left => 1, :right => 1
  text = ARGF.read
  text.gsub!(/[^\W\d_]+/) do |m|
    hyp.visualize(m).split(/(^\w|\w$)|-/).map{|t|
      t.split(//).sort_by{rand}.join
    }.join
  end
  puts text
  __END__


cheers,
andrew
