  • Renamed “Item” to “Row” so UI and scripts use same terminology.
  • Changes to the AppleScript dictionary:
    • Got a lot of good feedback in this thread.
    • I haven’t applied it all, but I did make a number of signifigant changes:
      • Removed child row and just use row
      • Document now maintains a collection of all rows
      • Each row now only maintains a collection of directly contained rows This is a change from previous behavior
      • I’ve also added a number of new scripting properties such as entire contents and container
    • More scripting documentation is now available.

One minor thing in the scripting interface:

Retrieving a URL for the root row will probably be a bit marginal and unusual:

tell application "Bike" to tell front document
    URL of root row
end tell

but if we do evaluate an expression like that we get a duplication of the document ID in the virtual row ID, and attempting to follow a link of the pattern:

bike://YZDjdHU_#YZDjdHU_

(where the duplicated ID is that of an actual document)

seems to trip a problem:

Termination Signal:    Illegal instruction: 4
Termination Reason:    Namespace SIGNAL, Code 0x4
Terminating Process:   exc handler [78837]

( perhaps more of a url-handling issue than a scripting interface issue ? )

Good catch, I’ll fix soon.

On that topic – the URL property appears to be defined for document objects, but while this returns a value immediately,

tell application "Bike"
	URL of first row of front document
end tell

I’m not sure whether the I error I get from evaluating URL as a direct property of document

tell application "Bike"
    URL of front document
end tell

Bike got an error: AppleEvent handler failed.

is expected ?

What is best practice, at this stage, for detecting childless ‘leaf’ rows ?

Is the best approach just to see whether the rows property evaluates to an empty list ?

Expand disclosure triangle to view AppleScript draft 
on isLeaf(bikeRow)
	using terms from application "Bike"
		{} = rows of bikeRow
	end using terms from
end isLeaf


--------------------------- TEST -------------------------
on run
	tell application "Bike"
		set doc to front document
		
		if exists doc then
			if my isLeaf(front row of doc) then
				"First row is a leaf"
			else
				"First row has child rows"
			end if
		else
			"No document open in Bike"
		end if
	end tell
end run

Or perhaps to check for an empty entire contents list ?

Expand disclosure triangle to view alternative isLeaf 
on isLeaf(bikeRow)
    using terms from application "Bike"
        {} is entire contents of bikeRow
    end using terms from
end isLeaf

I’m not sure, but I think checking count rows of bikeRow would be fastest.
