Get online info about any gem existing at rubygems.org

gemdetails.rb

# Alternative way of getting all Gem details using the official Rubygems REST API (thanks @qrush)

require 'open-uri'
require 'active_support/json'
require 'awesome_print'

ap ActiveSupport::JSON.decode(open("http://rubygems.org/api/v1/gems/#{ARGV[0]}.json"))

geminfo.rb

# Web scraping approach (ugly, I know)

require 'open-uri'
require 'nokogiri'

ARGV.each do |gem|
  puts '/' + '='*(gem.length+2) + '\\'
  puts "| #{gem.upcase} |"
  puts '\\' + '='*(gem.length+2) + '/'
  html = Nokogiri::HTML.parse(open("http://rubygems.org/gems/#{gem}"))
  info = html.xpath("//div[@id='markup']")

  puts info.children.map { |x| x.text.strip }.join('')
  puts
end

Thanks, I honestly had no idea about this cute REST API. :) Added another mini-script.

I can directly do this, too (works on Windows/Cygwin/Linux) --

ruby -r"awesome_print" -r"open-uri" -r"active_support/json" -e "ap ActiveSupport::JSON.decode(open('http://rubygems.org/api/v1/gems/rails.json'))"
