Atom and OS Version Text Expander Snippets (for OS X)

atom-version.rb

#!/usr/bin/env ruby

atom_version = `/usr/local/bin/atom --version`.chomp

print "Atom v#{atom_version}"

os-version.rb

#!/usr/bin/env ruby

hash = {}
key = nil
File.open('/System/Library/CoreServices/SystemVersion.plist').each_line do |line|
  case line
  when /<key>([^<]+)<\/key>/ then key = Regexp.last_match[1]
  when /<string>([^<]+)<\/string>/ then hash[key] = Regexp.last_match[1]
  end
end

print "#{hash['ProductName']} #{hash['ProductVersion']}"

I have a snippet av for atom-version.rb and a snippet ov for os-version.rb and finally a snippet vers that calls both.
