Script launcher via html page. Possible?

You could register your own URL scheme and associate that with a Automator app that does what you want.

Warning

URL schemes offer a potential attack vector into your app, so make sure to validate all URL parameters and discard any malformed URLs. In addition, limit the available actions to those that do not risk the user’s data. For example, do not allow other apps to directly delete content or access sensitive information about the user. When testing your URL-handling code, make sure your test cases include improperly formatted URLs.

Or why not just create a bunch of Automator Apps, or Automator Services, or Automator Dictation commands

For Automator Apps:

• You can place them on the Dock for a single click activation
• You can place them in a folder, and put that folder on the Dock, for a click on the folder, and a click on the app to activate
• You could put them in a Finder top tool bar
• You could put them in the Finder side-bar
• You could put them on the desktop.
• You could access them via the Launcher

Services would be accessible via the Applications Services menu, or Right-click on a file and access services from the right-click popup

You can assign hotkeys to services or apps

I have not played with Dictation commands, so either experiment or do some Google searching

The content of that webpage helper .zip download was created between 2006 and 2009. What do you think the odds are of this 10 - 13 year old code now working on macOS, especially with Apple's ever tightening security focus in Safari?

In todays more security-conscious world, I'm pretty sure having a web page launch some arbitrary document (let alone application) on your system would be considered a huge risk.

Indeed, hacking together a simple web page with links to files on disk sort of confirms this - Safari will activate the Finder and will select a specified file, but it won't launch/open it.

It may be possible digging deeper, but I suspect that a web front end to your scripts is going to be a long, hard road.

There are some URI prefixes that Apple has registered with the operating system for use with a browser. The following will open the Dictionary application from Safari (or Firefox) to the word "cat.". Either browser will pop a JavaScript dialog to challenge that you actually want open the dictionary application (on Mojave).

dict://cat

macOS Safari can launch Terminal and start an ssh connection using

ssh://remote.ssh.host

It can launch Mail and start a new mail with

mailto://email.address@domain.name

There are most likely other URL schemes that work, so I do not know why adding your own would not work.

Well, it's possible to launch itunes form a web page. You do get a message asking you if you know what you are doing.

Why don't you use the launcher?

Create a folder with all your applescript apps in the folder. Double click on the one you want.

I don't fully grok what you are trying to do here—

non-the-less html files of course can be created and run locally using Apache server/PHP.

the path would be http://localhost:8888
