Dependencies with Applescript....

Hi Guys,

When I have uninstalled my application, using the Applescript utility I created, it works fine. However, when double-clicking my script again, it doesn’t launch the script editor, instead, it launches a window stating that the application I had uninstalled was not found and it needed it. Oddly, when I re-install that application, I can now double-click my script to edit my code…that’s weird. Why is that?

Thanks and God Bless.

Ben.

AppleScripts like to be compiled. On launch, I assume that your script is trying to compile itself, and when a script compiles it looks for, among other things, every application that you have stated and, if it isn’t found, asks you to find it. This feature I assume is designed so that if you have a long piece of code with the name of one applicaiton spelled wrong, you don’t have to go hunting for it (obviously you can’t search-and-replace, because it’s misspelled. The short answer is that yes, it does need the application, and it want’s you to find it for it. If that didn’t make sense, read it again.

Your solution to this would be to
A) click cancel on this dialog and, if i’m right, watch your script open uncompiled or
B) Convert it into a droplet, something like:

on open theseItems
	tell application thisItem
		quit
	end tell
	delete thisItem
end open

This should quit and then delete any application you drop onto it. It compiles, but I have not tested it, and I assume that dropping anything other than an application would produce an error. If that were not the case, the item would be deleted. To correct this, it should become

on open theseItems
	set appName to name of thisItem
	if nameExtention of thisItem is "app" then
		set continueDelete to (display dialog "Are you sure you want to quit and delete " & appName & "?" buttons {"Yes", "No"} default button 2)
		if button returned of continueDelete is "Yes" then
			tell application thisItem
				quit
			end tell
			delete thisItem
		end if
	else
		display dialog thisItem & "is not an application." buttons {"OK"} default button 1
	end if
end open

Does that work?

Edit: I wasn’t clear on this… the script needs to be saved as an application/application bundle to work (I recommend Application Bundle- it’s universal), and running it from Script Editor will do absolutely nothing. You need to drop the file (or files, if you want to add a repeat to it) you want to delete onto the application, which should have this symbol: [url=http://www.vandogar.com/wp-content/uploads/2007/04/applescript_icon.png]http://www.vandogar.com/wp-content/uploads/2007/04/applescript_icon.png[/url]

Hi beiju,

Here are some things to make your script work.

Regards,

Craig


on open thisItem
	
	if (count of thisItem) > 1 then
		display dialog "Only one item at a time." buttons {"OK"}
		return
	end if
	
	--name and name extension are both part of the "info for" command
	set {appName, nameExtention} to {name, name extension} of (info for thisItem)
	
	
	if nameExtention is "app" then
		set continueDelete to (display dialog "Are you sure you want to quit and delete " & return & appName & " ?" buttons {"Yes", "No"} default button 2)
		
		if button returned of continueDelete is "Yes" then
			
			--you will get an error if you try to quit an app that is not
			--running so put it in a try block or you could check to
			--see if the app is running first
			try
				tell application thisItem to quit
			end try
			
			--to "delete" an item, move it to the trash
			--you can then empty trash
			tell application "Finder" to move thisItem to the trash
		end if
		
	else
		display dialog appName & " is not an application." buttons {"OK"} default button 1
	end if
	
end open

OK- thanks for that. I wouldn’t want ChristInBen to get mad at me!
P.S. You may want to correct some of my other answers ;)!
