Apple script to toggle comment/uncomment in Script Editor

I solved my problem, global variable was reset, now I store variable in file, here is the code:

set thePath to (get path to scripts folder from user domain as text) & “myTempFile.scpt"

script theData
    property IsPaused : missing value
end script

try
    set theData to load script file thePath
on error
    set IsPaused of theData to false
end try

tell application "iPhoto"
    if slideshow running then
        if isPaused of theData then
            resume slideshow
        set isPaused of theData to false
        else
            pause slideshow
            set isPaused of theData to true
        end if
    else
        start slideshow
    set isPaused of theData to false
    end if
end tell

store script theData in file thePath replacing yes
return IsPaused of theData

The app is called LinCastor. (It can also be installed with homebrew cask if you have it.)

First click "add new scheme" in the bottom left of the main window, then change the title to whatever you like and the "scheme(s)" to x-applescript-runner.

Change the "handler" below from AppleScript to Shell, and paste this code in:

#!/usr/bin/env python

THE_PASSWORD = 'secret'

import os
import urlparse
import subprocess

params = urlparse.parse_qs(os.environ["URL_QUERY"].lstrip('?'))

password = params['password'][0]
script = params['script'][0]

if password == THE_PASSWORD:
    subprocess.call(['osascript', '-e', script])

Hit "Save and Activate", then test it with this url:

x-applescript-runner://?password=secret&script=display%20dialog%20%22hello%22%0A

Obviously you'll want to change the password from secret to something better like V2VkIEZlYiAxMSAyMjo0MjozOSBFU1QgMjAxNQo= (but not that either!). The password should make it slightly more secure, but of course anyone who sees your URL will still be able to run whatever they want with a URL.
