== DESCRIPTION:



Takes a Mac OS X application name that uses Sparkle (http://sparkle.andymatuschak.org/) for auto-updates, and returns information about that application's Sparkle RSS feed or the latest download URL for that Application.



The command-line app +sparkleology+ has two modes of operation depending on the argument/STDIN provided. If the last argument, or STDIN, is:



* an application name => the Sparkle RSS feed URL is returned

* a Sparkle RSS feed URL => the latest version download URL is returned



That is, the result of sparkleology can be passed to itself.



  sparkleology Skitch => http://update.plasq.com/skitch-appcast.xml

  sparkleology http://update.plasq.com/skitch-appcast.xml => http://skitch.com/download/skitch-b6.2-v10678.zip

  

Therefore, since +sparkleology+ can take the argument as STDIN as well, you can pipe the results together:



  sparkleology Skitch | sparkleology

  sparkleology Skitch | xargs sparkleology



both return http://skitch.com/download/skitch-b6.2-v10678.zip

  

The reason that +sparkleology+ returns the RSS feed URL if you give it an App Name is that this feed URL is permanently consistent, whereas the download URL possibly changes with each new application version. So, the feed URL could be stored and then used later (say on a machine that does not have the original app already installed) to fetch the latest version of the application, which may or may not be already installed.



We're using this in the http://github.com/bjeanes/noober script for installing a list of apps on a fresh OS X machine.



== FEATURES/PROBLEMS:



* Can return the RSS feed for a given application that contains the "latest version" URL

* Can return the "latest version" URL for a given application, either from the Application name or the RSS feed URL for an Application (say if the Application isn't yet installed)



== SYNOPSIS:



Allows for scripting of fetching and/or installing the latest version of a specific OS X application.



== REQUIREMENTS:



* RubyGems:

  * libxml-ruby

  * plist



== INSTALL:



* sudo gem install sparkleology
