Adding multiple class files to an Applescript Studio project

Scripting Forums AppleScript Studio & Xcode

How do I get AS Studio to recognize classes in seperate .applescript files? This one’s got me stumped.

I have a project with a base Application.applescript and a second class.applescript file.

The base file should be able to create an instance of the class located in the class file. The build works fine, but when I run the app I always get the following error: “The variable myClass is not defined”.

How the heck to I get AS Studio to realize that it should use the other .applescript files too???

Thanks if you can help me with this one!

Use “load script” (see Standard Additions).

Many, many thanks – I knew it was stupid/basic, but for the life of me, I just couldn’t find an example anywhere!

:wink:

Thanks for pointing me in the right direction.

I found an example in the AS Studio example code that finally gave me what I needed to figure out what’s going on with AS when trying to use external script files to organize classes for a larger project. The original example code is located in the Examples:Applescript Studio:Unit Converter.

Here’s a short example that might come in handy for others trying to come to grasps with external class files and Applescript Studio:


-- In the Application.applescript file
on open names
   set ctrlLib to my loadScript("controller")     -- load the script located in the file "controller.applescript"
   set ctrl to controller of ctrLib                     -- store a copy of the controller object thats defined in "controller.applescript"
   display dialog(mGetUser() of ctrl as text)   -- Call a method on the controller object & display the result in a dialog
end open

-- Function that returns the path to the compiled scripts for this app.
on pathToScripts()
   set appPath to (path to me from user domain) as text
   return (appPath & "Contents:Resources:Scripts:") as text
end pathToScripts

-- Function that handles the loading of the external file.
on loadScript(scriptName)
   set appPath to (path to me from user domain) as text
   return load script file (my pathToScripts() & scriptName & ".scpt")
end loadScript

The Controller object is defined in a seperate applescript file called “controller.applescript”. Here’s the code of the file that is used in the above example.


script controller

   property user : "Mike"

   on mGetUser()
      return user
   end mGetUser

end script

This should show a dialog that says “Mike” (if I typed everything in correctly here!).

I found some other examples here and in the Applescript Studio docs, but they were all rather vague (doing to much other stuff at the same time).

I hope this helps someone avoid the hours of frustrating searching that I had to do to find this! :wink:
