One liner that works in Applescript but not in ApplescriptObjC?

Scripting Forums AppleScriptObjC and Xcode
#1

This one liner works fine in the Applescript Editor:


        tell application "Finder" to open POSIX file "/Development/Applescript/Rapport.docx"

However, it doesn’t when inserted in a newly created (with Xcode 5.1.1 under Mac OS X Mavericks 10.9.2) ApplescriptObjC project:


	on applicationWillFinishLaunching:aNotification
	    -- Insert code here to initialize your application before any files are opened
            tell application "Finder" to open POSIX file "/Development/Applescript/Rapport.docx"
	end applicationWillFinishLaunching:

I get the following error message:

I am an experienced Cocoa developer, but an Applescript newbie.

What did I miss?

Thanks a million

Hi,

in AppleScriptObjC you have to write

tell application "Finder" to open "/Development/Applescript/Rapport.docx" as POSIX file

Then why not the Cocoa way ?


current application's NSWorkspace's sharedWorkspace()'s openFile:"/Development/Applescript/Rapport.docx"

Thanks for the solution. Are there many gotchas such as that one? Are the differences documented somewhere?

The reason for doing it in Applescript is: I want to learn it!

Any fast track reading recommendation?

Now the example I gave is a reduction of a larger problem. Hopefully, your solution will help for that one as well. If not, I’ll followup.

Thanks again.

Apple’s documentation is quite poor, the best reference is Shane Stanley’s book AppleScriptObjC Explored

There are a few similar: you can’t use terms like file, alias and date as specifiers, but rather you have to use them as coercions.

These apply only when using ASObjC in Xcode projects – not in ASObjC-based libraries.

(The reason is because specifiers always need a parent specifier, and the parent of an ASObjC class is is a Cocoa class, not AppleScript, and hence the specifier can’t be resolved.)
