Hi, Adam.

There is no variable ‘s’, so maybe one of the apostrophe-s-es has come adrift. Just guessing, but do you have an OSAX or something with the keyword ‘stuff’? I seem to remember having one on my old 4400 which used the StuffIt engine.

On the other hand, the ‘stuff’ variable is in the previous version of the script and didn’t cause you any trouble.

The conflict with Script Debugger 4.5 is the word specifier as a variable – it’s a dictionary word in SD4.5. Changing it to “spec” does the trick for both compilation AND operation. Works a treat, Nigel.

This is a very impressive script and will help me greatly!

I did have an execution error and needed to add several ‘& tab’ pairs to the ‘set tabs’ line.

Hi. Welcome to MacScripter.

Thanks for the feedback. I’ve edited the script above in the light of your and Adam’s comments. Twelve tabs weren’t enough?! :o

Hello!

I got some Internal Table overflow errors, so I tinkered the Brilliant script to just give one chunk of output at a time, either window or menu.

I hope you forgive me!

I’ve made a few improvements to the script in post #17. Details at the bottom of the post.

In the latest version of Lion (10.7.5) and Script Debugger 5.0.4 the line (which is fine in AppleScript Editor):

if (elementCount is 1) then set specifier to text 1 thru text item j of thisLine

fails because specifier is a key word in SD’s dictionary. Changing specifier to _specifier everywhere solves that problem for SD users.

Further of course, users of this script must have a copy of Nigel’s Insertion Sort script or the line loading it will fail. Here’s my copy:

(* Insertion sort
Algorithm: unknown author.
AppleScript implementation: Arthur J. Knapp and Nigel Garvey, 2003.

Parameters: (list, range index 1, range index 2)
*)

on insertionSort(theList, l, r)
	script o
		property lst : theList
	end script
	
	-- Process the input parmeters.
	set listLen to (count theList)
	if (listLen > 1) then
		-- Negative and/or transposed range indices.
		if (l < 0) then set l to listLen + l + 1
		if (r < 0) then set r to listLen + r + 1
		if (l > r) then set {l, r} to {r, l}
		
		-- Do the sort.
		set u to item l of o's lst -- The highest value sorted so far!
		repeat with j from (l + 1) to r
			-- Get the next unsorted value.
			set v to item j of o's lst
			if (v < u) then
				-- If it's less than highest sorted value, initialise the insertion location to the beginning of the range. This will usually be changed below when a more suitable slot's found.
				set here to l
				-- Work back through the already sorted items, moving up those with greater values than this one, until a lesser or equal value or the beginning of the range is reached.
				set item j of o's lst to u
				repeat with i from (j - 2) to l by -1
					tell item i of o's lst
						if (it > v) then
							-- Greater value. Move it up one position.
							set item (i + 1) of o's lst to it
						else
							-- Lesser or equal value. Set the vacated slot after it as the insertion location.
							set here to i + 1
							exit repeat
						end if
					end tell
				end repeat
				-- Insert the value for insertion at the appropriate location.
				set item here of o's lst to v
			else
				-- The value's greater than or equal to the highest sorted so far. It's now the highest itself.
				set u to v
			end if
		end repeat
	end if
	
	return -- nothing.
end insertionSort

Thanks, Adam. I’d regard the ‘specifier’ thing as a fault in Script Debugger. Its own keywords shouldn’t get in the way of the scripts it’s running or editing. But I’ve changed ‘specifier’ to ‘_specifier’ in the posted code.

The sort is just a cosmetic nicety from my own copy of the script and I’ve now cut it from the posted version.

What’s interesting about “specifier” is that it works in OS X 10.8, but not in 10.7 or 10.6. What happens is that the word specifier is changed to the word reference by the compiler. For some reason the AppleScript Editor deals with that, but Script Debugger does not. The author of SD is looking into it.

I assume you meant to include a “not” in there, but what you’re asking for is probably impossible given the way AS works. Here’s a counter example:

set language to 5

That compiles fine in Script Debugger 5, with language as a variable, but it won’t compile in ASE because language is one of its keywords. I don’t think there’s anyway around that sort of thing, other than having a minimal dictionary and using multi-word terms as much as possible. (Earlier versions of Script Debugger used to offer the option of turning the dictionary off to avoid the problem, but I don’t know that that is practical with Cocoa scripting.)

The problem with specifier stems in part from the decision at some stage to change the terminology used in AS dictionaries. Where once, for example, the move command would specify a direct parameter of type reference, it now specifies type specifier. But the specifier type isn’t actually defined anywhere, so it’s a type that’s a bit in no-man’s land.

Script Debugger has actually defined the specifier type in its dictionary, and I suspect that’s a sensible thing to do. Making it a synonym for reference was required to avoid the term reference compiling as specifier because they both point to the same thing (Cocoa’s NSScriptObjectSpecifier).

Probably more than anyone wanted to know…

Oops. Yes. I was concentrating so hard on trying to get “its” and “it’s” right, I missed that. Now corrected.

Thanks for the background. I hadn’t noticed the ‘language’ thing before.

In sd-talk today, Matt Neuburg points out that on p. 331 of his “AppleScript: The Definitive Guide” (which I have) in the chapter on Dictionaries and wildcards, he points out:

Just for interest, I’ve had a go a “sed” alternative to the vanilla AppleScript formatting code in my script. It’s not appreciably faster and is noted separately in Edit 4 at the bottom of post #17 1.

I added memory - when this script is saved and runs as an applet, it remembers and re-selects from the list (if that is still running) the app you previously chose.

Cool, I’m surprised at how robust this script has proven. Ten plus years, and only minor tweaking needed in a GUI script? That’s practically heresy.

Small correction: I’m Squalene over at Mac OS X Hints, not ‘Squaline’.

Nigel — this UI parsing script is fantastic.

Now…imagine this. Instead of text output, send your parsed list into OmniOutliner. Then you generate a very neat outline which is parseable using Applescript (or Javascript if you prefer).

So in OmniOutliner you might have:
A. Menu Bar 1
1. Menu “File”
a) Menu Item “Quit”
(ignore obvious errors in how UI scripting lists these things…it’s just an example)

Then you click on what you want your UI script to run, selecting it, and run a script which does this:

tell application "OmniOutliner"
	tell its document "UI Listing for TextEdit Menubar"
		set mySel to selected rows
		set myAncestors to (every ancestor of item 1 of mySel)
	end tell
	set thetext to "CLICK " & name of item 1 of mySel
	repeat with x in myAncestors
		set thetext to thetext & "OF " & name of x
	end repeat
	thetext
end tell

If you select ‘a) Menu Item “Quit”’ and run the script, it returns something like: click menu item “Quit” of Menu “File” of Menubar 1
Then you just paste that into your script.

Hi Vince.

Thanks for the feedback. That sounds like a fun exercise for an OmniOutliner user.

It may be possible to implement a similar idea in BBEdit — by having the elementListing() handler return both the tabbed text and another with unedited lines, opening these in different windows. It would then be a matter of selecting text in the tabbed-text window and having a script return the equivalent paragraph(s) from the other. But I haven’t looked into this deeply.

Indeed.

If you have Omnioutliner, and you have previously downloaded Omni’s “Sample Applescripts”, there is a script in there which takes tabbed outlines and converts them to Omnioutliner. But it is rather slow — doing the menubar of Text Edit took over 4 minutes to convert. I think part of the slowness of that script is that it counts tabs by examining every character in every line (suspect the line “repeat with aChar in every character of aLine” is part of the problem?) . That should be something that could be sped up, maybe by just counting tabs and not everything else…. Once it is in Omnioutliner, the script to generate your Applescript GUI scripting line is pretty simple — similar to what I posted above and with a few modifications in the text output. For example, “select” vs “click” depending on the UI element you are activating.

Alas, I do have OmniOutliner — great program, but I consider the $50 I spent on Bill Cheeseman’s “UI Browser” to be money well spent! Just the “show UI element” feature is worth the price of admission - you just click on the element you are interested in and the program generates the AS GUI script you need. No guessing about the elements listed in an outline. https://pfiddlesoft.com/uibrowser/index.html 3

Attached below is the Omnioutliner import script from their sample scripts.

				set parentRow to parent of parentRow
			end repeat
			make new row with properties {topic:(content of aLine)} at end of parentRow
		end if
	end tell
end CreateRow

That handler could be sped up. Similarly, the FetchClipboardAsList() handler only needs to be:

on FetchClipboardAsList()
	return paragraphs of (the clipboard)
end FetchClipboardAsList

But they’re just AppleScript text work, so the difference shouldn’t be very great. What does seem laborious, just looking at the script (and, as you’ll have guessed, I don’t have OmniOutliner myself), is the fact that the ‘rows’ are added to the document one at a time, with repeats inside the application each time to establish the parent of each one. I assume this is to create the indent structure in the absence of the stripped tabs and that OmniOutliner itself has no native way to turn a tab-indented text into the required ‘row’ structure.

Instead of searching back through the parents within the application every time, I’d be inclined to try maintaining an AppleScript list as a look-up stack. Does this work?

A few years later and the script still works (specifically, the post 33 variant). After noticing the thread referenced elsewhere, I read through it and wanted to add something regarding omnioutliner.

Omnioutliner has an import command and it is tab-aware (which is only to be hoped for given that one the exports is to tabbed text).

With the textedit menus, it took just over a second to import them. I delete the Apple menu and the Services sub-menu as they don’t have anything to do with the app. The full import for me is 400 lines and it becomes 218 after excluding those two menus.

set inFile to (path to desktop as text) & "tex_menus.txt" as text
tell application "OmniOutliner"
	activate
	tell document 1
		delete children -- delete everything
		make new row -- need at least one row
		
		import file inFile to before first child
		-- expandAll child 1
		delete last child -- previously created row
		delete row "menu bar item \"Apple\""
		delete row "menu item \"Services\""
	end tell
end tell

NB A larger menu system, like that of firefox (3400 rows, due to bookmarks), takes 5 seconds on my old mac. I comment out the expandAll as it’s the slowest part of the script and may not be desired. Also, I do the make/delete row dance here but it’s easy enough to insert the imported branch anywhere within a typical document.

Of course, if all of your tabbed text is on the clipboard, you can also just paste it into OO and it will appear as an outline as long as you have an entire row selected when you paste the text. It can be done in a script like this:

tell application "OmniOutliner" to pbpaste at before first child

There isn’t any need to rely upon UI scripting for such tasks.
