counts words for an article I'm writing

word_count.rb

#!/usr/bin/env ruby
require 'rdiscount'
require 'nokogiri'

words = 0
content = $stdin.read

html = RDiscount.new(content).to_html

doc = Nokogiri::HTML(html)

codes = doc.css("pre code")
codes.each do |code|
  words += code.inner_html.split("\n").size * 15
  code.parent.remove
end

words += doc.inner_text.split(/\s+/).size

puts words

puts "You need to cut #{words - 2700} words"

Thanks for the gist! Just a small note: only works for me if I use content = ARGF.read instead of content = $stdin.read

Yes thanks a ton for this! I got a minor error when I ran it too.

wc.rb:2:in require': no such file to load -- rdiscount (LoadError)`

I'm not a ruby dev so maybe it's obvious but I had to add the following line above the other required gems and now it works perfect:

require 'rubygems'
