Turns a11y-style text back into English. Or tries to, anyway.

s4d.rb

# ruby s4d.rb "h3o w3d" 5

text = ARGV.first || "y1u a5t p1l? j2t w4d to s1y hi"
times = (ARGV[1] || 1).to_i

words = File.readlines('/usr/share/dict/words')
            .map(&:downcase)
            .map(&:chomp)

times.times do
  puts text.gsub(/\w+/) { |word|
    words.select { |realword|
      realword.start_with?(word[0]) &&
      realword.end_with?(word[-1]) &&
      realword.length == word[1..-2].to_i + 2
    }.sample
  }
end
