applescript returning execution error

Hi everyone,
I'm using Applescript to get selected events from Apple Calendar, building on
https://macscripter.net/viewtopic.php?id=45861
When I try to parseDefaults I get execution error back when executed inside Livecode. Does anyone have any idea why?
FYI I have given Livecode full disk access in security settings.
Apple script snippet:
Code: Select all
set defaultsReply to (do shell script "defaults read com.apple.ical SelectedEvents")
set selectedEvents to parseDefaults(defaultsReply)
return selectedEvents

Hi,
I selected an event and tried
Code: Select all
get shell("defaults read com.apple.ical SelectedEvents")
and it returned
{
iCal = (
"9F712C50-5B6D-4385-B0DC-3F19F4957B8F"
);
}
without an event selected it returned
{
iCal = (
);
}
I am using LC 9.6.9 rc1 on macOS Monterey
Maybe that helps.
Kind regards
Bernd

Itś the next line in the sample code that throws the exception....

Rod,
Your script runs in ScriptDebugger(when adding on parseDefaults(resultText) handler
Attention, this is AppleScript, not LCS
Code: Select all
set defaultsReply to (do shell script "defaults read com.apple.ical SelectedEvents")
set selectedEvents to parseDefaults(defaultsReply)
return selectedEvents
on parseDefaults(resultText)
set localUIDs to {}
set {TID, text item delimiters} to {text item delimiters, quote}
set resultItems to text items of resultText
set text item delimiters to TID
repeat with i from 1 to (count resultItems)
if i mod 2 = 0 then set end of localUIDs to resultItems's item i
end repeat
return localUIDs
end parseDefaults
I'm running run out of ideas.
Kind regards
Bernd

Thanks Bn, yes does run in script editor, but not in Livecode, and it's not obvious why...
Will let you know if I discover anything more, otherwise will file as a bug report.

Klaus,
Rod knows that, "Scripteditor" is the name of Apples App to run AppleScript. "ScriptDebugger" is also an app to run AppleScript with more options than Apple's Scripteditor.
Kind regards

Rod,
I could not resist to play around with the AppleScript. I found a way that it works.
Note: this is AppleScript, not LC script
Code: Select all
set defaultsReply to (do shell script "defaults read com.apple.ical SelectedEvents")
set localUIDs to {}
set {TID, text item delimiters} to {text item delimiters, quote}
set resultItems to text items of defaultsReply
set text item delimiters to TID
repeat with i from 1 to (count resultItems)
if i mod 2 = 0 then set end of localUIDs to resultItems's item i
end repeat
return localUIDs
resolving the subroutine somehow made it work. (?)
Please note that it can take up to a couple seconds until iCal updates the database.
The AppleScript works even when the Calendar App is not open.
Kind regards
Bernd

Awesome Bernd, that was what I was going to try next. I will give this a go now.
It is very odd that calling this subroutine throws exception but "in-lining" it is fine. I wonder if we should try to reduce it to minimum viable bug producing recipe and file as a bug report....

Now that we've got Applescript returning the selected event in the Calendar, I'm trying to get details of the event, like this:
Code: Select all
set defaultsReply to (do shell script "defaults read com.apple.ical SelectedEvents")
set localUIDs to {}
set {TID, text item delimiters} to {text item delimiters, quote}
set resultItems to text items of defaultsReply
set text item delimiters to TID
repeat with i from 1 to (count resultItems)
if i mod 2 = 0 then set end of localUIDs to resultItems's item i
end repeat
tell application id "com.apple.iCal" -- Calendar
set theProps to properties of event id (item 1 of localUIDs) of (last calendar whose name is "Work")
end tell
return theProps
This works in OSX Applescript Script Editor app, but not when executed in Livecode.

Rod,
The script worked for me after giving Livecode permission to access Calendar(iCal) in Security Settings.
The funny thing is that your original script started to work when the permissions were given for LC to access iCal...
Kind regards

Odd, shouldn we get a permissions request if this is needed? So youŕe saying you went in to security permissions and granted permissions manually... interesting. OK I will give this a go tomorrow!

In Automation pane of Privacy and Security I see LiveCode 10.0.0 (dp4) listed with permissions for Daylite, Chrome,DropDMG,System Events and Calendar. I don't see Livecode 9.6.4 listed, which is what I am running. When I test in Livecode 10.0.0 (dp4) I get the same error.
I wonder if I have to reauthorse the app. Reading up on this, some interesting links:
Using above advice I ran
-- this resets the automation pane completely. After doing this I launched Livecode 9.6.4 and execute the applescript. I get prompted for permission to automate Calendar (click OK). The script returns execution error. When I check in automation pane in security and privacy, it shows Livecode 10.0.0 (dp4) even though that's not the version of Livecode I had open...
I also tried building my app to a standalone and executing the applescript from there. I got prompted to automate Calendar (click OK to accept) and the script returns execution error.

From this post
https://www.felix-schwarz.org/blog/2018 ... cos-mojave I found that opening this URL will take user directly to the automation pane in security and privacy.
It works in Livecode:
Code: Select all
launch url "x-apple.systempreferences:com.apple.preference.security?Privacy_Automation"
This is a useful tip for anyone building apps that need user to grant permissions, as it will take them directly to the right place to review.
