Open all links in Safari's Reading List in tabs.

open_reading_list_in_tabs.rb

#!/usr/bin/env ruby
# $ gem install CFPropertyList
require 'cfpropertylist'

path = File.expand_path '~/Library/Safari/Bookmarks.plist'
plist = CFPropertyList::List.new file: path

list = plist.value.value["Children"].value.select do |item|
  if title = item.value["Title"]
    title.value == 'com.apple.ReadingList'
  end
end.first.value["Children"].value

bookmarks = list.map do |item|
  item.value["URLString"].value
end.reverse

puts "Opening #{bookmarks.count} tabs "

bookmarks.each do |url|
  `osascript -e 'tell application "Safari" to tell window 1 to make new tab with properties {URL:"#{url}"}'`
  print '.'
end

puts ''

Anything I'm doing wrong or is the script broken?
Best regards
