Question

I’m starting to poke around with Applescript and am looking at writing a few scripts for managing windows. A common task they will all need is to get the current screen size.

I’ve created a screen_size subroutine that seems to work, and I want to be able to share that with all my scripts. However, I can’t figure out a way to put that in a separate file that I can load in my other scripts. I tried creating a separate screen_size.scpt file and use load script "screen_size.scpt", but I get an error about “can’t make “screen_size.scpt” into a type file”.

There has to be a way to do this, but I haven’t been able to find anything online about how to do it.

EDIT:

The POSIX stuff suggested isn’t working for me. I’m able to create the file object, but it refuses to convert to an alias, saying it can’t find the file (looks like the POSIX file stays relative instead of expanding fully).

I found a suggestion online to use Finder, and have gotten the following working to get an alias:

tell application "Finder"
  set _myPath to container of (path to me) as text
end tell

set _loadPath to (_myPath & "screen_size.scpt")
set _loadAlias to alias _loadPath

However, the next line fails with a syntax error, claiming that _loadAlias isn’t a variable:

property _ScreenSize : load script _loadAlias

Every variation of this I’ve tried (doing the alias in the load call, etc) fails, always claiming the variable doesn’t exist, even though I know it’s being set and working as I can display it. What’s going on? Why is it claiming a variable doesn’t exist when it obviously does?

Answer 1

AppleScript is doing some really weird things when saving and I haven’t figured out what’s going on, but I ended up getting something to work.

Here’s what I have:

on load_script(_scriptName)
  tell application "Finder"
    set _myPath to container of (path to me) as text
  end tell

  set _loadPath to (_myPath & _scriptName)
  load script (alias _loadPath)
end load_script

set _ScreenSize to load_script("screen_size.scpt")

set _bounds to _ScreenSize's screen_size()
-- ...

The other answers were saying to set _ScreenSize as a property, but that would cause a syntax error which prevented me from ever saving the file. When I did it just using set it worked.

I wasn’t ever able to get the POSIX path stuff suggested to work, but poking Finder for the path worked fine.
