SKProgressBar 1.0, a fully scriptable progress bar

StefanK · February 14, 2013, 5:58am

the cryptic raw events should compile as

start animation
increment by
stop animation

Of course I tested the application. It works fine on my machine (also 10.8.2).
Have you deleted the 1.0 version?

Hi Stefan,
I can confirm Adam’s post about the new version. It hangs on or after “set indeterminate to false” by inserting this in the script:

	tell progress bar
		activate
		set indeterminate to false
		«event PrBrStMn» ”> this
		tell current application
			-- do shell script ...
		end tell
		repeat 10 times
			«event PrBrIcRm» given «class bYVl»:10.0 ”> this
			delay 1
		end repeat
		«event PrBrSpMn» ”> this
	end tell

and these are the script replies:

tell application "SKProgressBar"
	set image path to "path:to:me:Contents:Resources:my.icns"
	set minimum value of progress bar to 0.0
	set maximum value of progress bar to 100.0
	set current value of progress bar to 0.0
	set show window to true
	activate
	set indeterminate of progress bar to false
	«event PrBrStMn» progress bar
		--> error number -1708
Result:
error "SKProgressBar got an error: progress bar doesn't understand the «event PrBrStMn» message." number -1708 from progress bar

I too have 10.8.2 and I deleted all copies of the v1.0 of SKProgressBar.app, except the Time Machine.

For me, in Snow Leopard, the script compiled correctly but, when run, hung for several seconds until the system’s “application downloaded from the Internet” warning appeared. Since that was OK’d, everything seems to work fine.

PS. If I substitute Adam’s and flex20’s raw codes for the keywords, they don’t compile as keywords in the AppleScript Editor window and the script suffers the same problems when run. Maybe there are terminology clashes on Adam’s and flex20’s systems causing miscompilations?

PPS. If I save the correctly compiled script, close AppleScript Editor, zap SKProgressBar from my startup disk, and reopen the script in AppleScript Editor, the raw codes are different from those reported by Adam and flex20:

	tell «class cRpB»
		set «class iDtM» to false --> default is true
		
		«event pGbRStMn»
		repeat 6 times
			«event pGbRIcRm» given «class bYVl»:10.0
			delay 1
		end repeat
		«event pGbRSpMn»
		
	end tell

PPPS. What’s the betting Script Debugger’s involved somehow?

Shane_Stanley · February 14, 2013, 12:21pm

The problem seems to be that Stefan has changed the four-letter codes between versions, and flex20 and Adam must have the old version still on their systems.

In particular, increment has changed from PrBrIcRm to pGbRIcRm, start animation from PrBrStMn to pGbRStMn, and stop animation from PrBrSpMn to pGbRSpMn.

I’m not sure why he made the change, but the solution is to remove the previous version, and convince ASE to remove it from its cache.

Hi Shane,
I have actually deleted what I think were all traces of v1.0, except for whatever is in the Time Machine. But just to make sure after your post, I booted on my clean volume I maintain for just such testing.

Then, I ejected my main volume, as well as a scrap volume I have, to make sure that nothing can be accessed on them.

Finally I run my script bundle with the SKProgressBar v1.0.1 in it. It crashed at the same place with the same message.
So, I really don’t think that the cause of the crash has anything to do with a clash of versions.

I also want to point out that I have now two scripts with integrated SKProgressBar v1.0 (I only discovered this app a few days ago) and they work perfectly on my 2010 iMac with 10.8.2.

Cheers, Chris

Sorry about the confusion.

I really can’t remember why I changed the four-character codes.
There were some inactive NSScriptCommand classes in the project, so I guess
I changed the respective commands from verb-first to object-first (Shane you know what I mean )
To be consistent the first 4-character codes have been changed to the parent class.

flex20 · February 14, 2013, 7:48pm

Hi Stefan,
Will you now release/post a new version? I checked v1.0.1 you posted at #7 above, but it is still yesterday’s version.
It’s no rush really, because v1.0 is working just fine.
Regards,
Chris

Shane_Stanley · February 14, 2013, 10:05pm

If the message contains “PrBrStMn”, then it’s using the old terminology. It may be just ASE caching it (this is another good reason to use Script Debugger). But whatever, the only place PrBrStMn is used is in the old version.

Try copying the code in Nigel’s message and see what it compiles to.

Shane_Stanley · February 14, 2013, 10:07pm

Ah, I was wondering why you did it

Nigel_Garvey · February 14, 2013, 10:54pm

Did you recompile the script against the new version, making sure the source code in your editor contained all the original keywords?

flex20 · February 15, 2013, 10:01am

OK, this is what I just did again:

restored my clean test volume from a “virgin” 10.8.2 disk image with my basic configuration and disabled Spotlight;
restarted from it and then ejected my main volume to isolate the clean test volume;
opened a new blank script and copy/pasted the code from my original script and then saved the new script as a bundle with a new name;
navigated to it’s Resources folder and copied the SKProgressBar.app v1.0.1 to it;
compiled and saved it; (no app v1.0 or a script containing it, were in sight or ever run on that clean volume)
run it.
It crashed again at the same place, with the same raw codes but, slightly changed script replies:

tell application "SKProgressBar"
	tell progress bar
		activate
		set indeterminate to false
		«event PrBrStMn»
		tell current application
			-- do shell script ...
		end tell
		repeat 10 times
			«event PrBrIcRm» given «class bYVl»:10.0
			delay 1
		end repeat
		«event PrBrSpMn»
	end tell
	quit --> error number 0
end tell
(*Replies
tell application "SKProgressBar"
	activate
	set indeterminate of progress bar to false
	«event PrBrStMn» progress bar
		--> error number -1708
Result:
error "SKProgressBar got an error: progress bar doesn't understand the «event PrBrStMn» message." number -1708 from progress bar*)

While the script was frozen and SKProgressBar was still running, I checked that its version was indeed 1.0.1.
So, I think that shows that v1.0.1 in a clean script, running on a clean volume is still crashing with a reproducible error.

Cheers, Chris

StefanK · February 15, 2013, 10:04am

please replace

«event PrBrStMn» with start animation
«event PrBrIcRm» given «class bYVl»:10.0 with increment by 10
«event PrBrSpMn» with stop animation

Shane_Stanley · February 15, 2013, 10:17am

That’s never going to solve the problem if the code you’re pasting contains the old codes. Either use the new codes, or just rewrite the commands to use the English commands (set current value, increment, etc).

Nigel_Garvey · February 15, 2013, 11:12am

Hi Stefan.

The changes are rather disastrous, since they break every script compiled against the previous version(s) of your app ” which is inconvenient for all your existing users, not just those who don’t know about compiled tokens.

In the past, when Apple or anyone wanted to change an event or class code, they might give the old code a new keyword ” say start animation (old) ” and allow it still to work. That way, existing scripts wouldn’t break and new ones would get the new token for the original keyword. Anyone seeing start animation (old) when opening an older script in their editor could simply delete the b[/b] and recompile the script to get the new token. I don’t know how feasible this is nowadays, but something like it should be considered.

StefanK · February 15, 2013, 11:35am

Hi Nigel,

thanks for the suggestion, I did that, same link

flex20 · February 15, 2013, 2:44pm

Hi Shane,
What I copied was the absolute original code from v1.0 of my script, I had been using before I even heard of this progress bar app. Then, I modified my original code, by copy & pasting from Stefan’s script at the top of this page, so as to enclose the action I wanted to attach the bar to (i.e. the action is inserted between ‘start animation’ and the increment repeat block).

Unless, I really misunderstand what you are saying (and that’s a very distinct possibility), I think that what I’ve done is in fact equivalent to retyping the whole code. Please comment if you think I’m wrong,

Cheers, Chris

flex20 · February 15, 2013, 10:16pm

Many thanks Stefan,
The new version 1.0.1(3) works perfectly now in 10.8.2
May I suggest to update the link at #1 to always point to the latest version, to make it easier to find.

I had to update 13 instances of SKPB 1.0 code, but hey, the end result is great

Not so great was that I was about half through updates, busily retyping over the three commands, before I finally noticed Nigel’s suggestion

Cheers,
Chris

Shane_Stanley · February 15, 2013, 10:37pm

No, that sounds right. But the old app’s terminology was being accessed somewhere…

Adam_Bell · February 15, 2013, 11:39pm

At some point Stefan, I’m hoping there will be a link to disk image download with the latest application version, the read me document and a sample script that works without any editorial repairs. Without that, you’ll be deluged with emails when it doesn’t work for new users.

For now, the best bet is to go to post #1 and download SKProgressBar 1.0 which after unpacking is a dmg. Remove the Readme and Script files, but not the application and eject the dmg.

Then go to post #7 and download SKProgressBar 1.0.1. Now you can compile the script. In the script, you may find the word (old) in several places. Remove those and recompile. Now you’re good to go.

jswingchun · October 16, 2013, 2:45pm

I know this is kinda old, but I just wanted to say thanks. This is awesome. I added it to an ancient script that I am updating and it saved me a ton of work.
