コイツ誰？って思ったとき用のearthquake.gemプラグイン(要libnotify)

who.rb

#coding: utf-8

begin
  require 'libnotify'
  require 'tempfile'
  require 'open-uri'

  Earthquake.init do
    help :who, 'show user name and icon', <<-HELP
      ⚡ :who yohfee
    HELP

    command :who do |m|
      user = twitter.show(m[1])

      if user.key?("error")
        puts user["error"]
      else
        Tempfile.open $$.to_s do |file|
          begin
            file.binmode
            file.write open(user["profile_image_url"]).read
            file.close

            Libnotify.show summary: "#{user["screen_name"]} (#{user["name"]})",
                           body: ERB::Util.html_escape(user["description"]),
                           icon_path: file.path,
                           timeout: 1.0
          ensure
            file.unlink
          end
        end
      end
    end
  end
rescue LoadError
