littlebirdyで閲覧パスワードがかかってないファイルの保護をショートカットで外す

littlebirdyをベースに、パスワード保護がないファイルの保護を自動で外すlittlebirdy-nopasswordを作った
github.com

これをAutomatorのService（AppleScript使用）で自動化する。
phpとgsのインストールが必要

brew install ghostscript
brew install php

Automatorを起動してQuickAction（旧Service）を作成

AppleScriptを選択。No input, Any applicationを選択して以下のスクリプトを記述.

tell application "System Events"
	tell process "Preview"
		set thefile to value of attribute "AXDocument" of window 1
	end tell
end tell

-- display dialog "my variable: " & thefile
-- display dialog quoted form of replaceText(thefile, "%20", space)
set thefile to replaceText(thefile, "%20", space)
set thefile to replaceText(thefile, "File://", "")
-- set newFile to POSIX file thefile
set thefile to do shell script "/usr/local/bin/php -r 'echo urldecode(\"" & thefile & "\");'"

do shell script "/usr/local/bin/littlebirdy-nopassword " & thefile

tell application "Preview" to close window 1
do shell script "open " & thefile

to replaceText(someText, oldItem, newItem)
	(*
     replace all occurances of oldItem with newItem
          parameters -     someText [text]: the text containing the item(s) to change
                    oldItem [text, list of text]: the item to be replaced
                    newItem [text]: the item to replace with
          returns [text]:     the text with the item(s) replaced
     *)
	set {tempTID, AppleScript's text item delimiters} to {AppleScript's text item delimiters, oldItem}
	try
		set {itemList, AppleScript's text item delimiters} to {text items of someText, newItem}
		set {someText, AppleScript's text item delimiters} to {itemList as text, tempTID}
	on error errorMessage number errorNumber -- oops
		set AppleScript's text item delimiters to tempTID
		error errorMessage number errorNumber -- pass it on
	end try
	
	return someText
end replaceText
