# SweDB XMLTV Grabber for EyeTV
# by Henrik Nyh <http://henrik.nyh.se> under the MIT License.
#
# INSTALLATION
#
# Configure the list of channels below and run this script as a cron job, e.g.
#
# 0 */12 * * * ruby /path/to/this/script.rb
# to run it every 12 hours (suggested since cron jobs don't run if the computer is off).
#
# Every time it runs it will get schedules for those channels and import them into EyeTV.
# The script uses conditional GET to only update files if they've changed.
# If you're on OS X Mavericks, you probably need to run this for the script to work:
#
# xcode-select --install
# sudo gem install hpricot
#
# If you're on Lion or Mountain Lion, install Xcode and its command-line tools and then run:
#
# sudo gem install hpricot
#
# On Snow Leopard, it should just work.
#
# CHANGELOG
#
# 2015-06-17 1.6: New root URL.
# 2013-10-25 1.5: Unbreak on Mavericks.
# 2012-01-14 1.4: cron example is once per 12 hours, not once a minute every 12th hour.
# 2009-05-05 1.3: MIT License.
# 2008-10-30 1.2: EyeTV no longer steals focus on import.
# 2008-09-15 1.1: Always update channel list; not just if updated on server. Don't break on 404.
# 2008-03-09 1.0: First version.
# Use ids as listed in http://xmltv.tvsajten.com/channels.xml.gz.

Någon rapporterade följande fel – kanske nån annan som har samma:

Tydligen hade någon av de senaste OSX-uppdateringarna ändrat säkerhetsinställningarna till att endast tillåta exekvering av mjukvara från ”App Store och angivna utvecklare” (Systeminställningar -> Tillåt program hämtade från -> Säkerhet och integritet). Så simpelt, men ändå så svårt att finna.

Det var troligtvis detta som förhindrade Ruby att laddas in korrekt och därmed även skriptet.
