Rename TV Episode video files using data from the TVDB api and add the season and episode number to the file name. For this to work the name of the file should contain the episode name in it.

gistfile1.rb

require 'xmlsimple'

# XML file was retrieved using TVDB api
doc = XmlSimple.xml_in('/Users/xyz/smurfs.xml')

doc['Episode'].each do |episode_hash|
  # Find the next valid episode (with a season and episode number)
  if episode_hash['SeasonNumber'][0].class == String && episode_hash['SeasonNumber'][0].to_i == 5
    episode_season = episode_hash['SeasonNumber'][0].rjust(2, "0")
    episode_num = episode_hash['EpisodeNumber'][0].rjust(2, "0")
    episode_name = episode_hash['EpisodeName'][0]
    episode_fullname = "The Smurfs S#{episode_season}E#{episode_num} - #{episode_name}"
    # Find the file name which contains that episode name
    f = Dir.glob("./*#{episode_name}*", File::FNM_CASEFOLD)[0]
    # Rename the file to have the right season and episode number
    if f
      puts "Renaming #{f} to #{episode_fullname + File.extname(f)}"
      File.rename(f, episode_fullname + File.extname(f))
    else
      puts "Could not find file corresponding to #{episode_fullname}"
    end
  else
    # puts "Skipping #{episode_hash['EpisodeName'][0]}"
  end
