Help adding app to KUAL

[handyguy]

Hi all,
I am trying to add a python script as an option within KUAL.
I have created what I understand are the folder structure and files needed.
e.g. extensions/clock and extensions/clock/bin
In /clock are the two files menu.json and config.xml
In /bin are clock.sh and all the python programs
config.xml contents:

{
        "items": [
                {"name": "Clock", "priority": 1, "action": "bin/clock.sh"}
        ]
}

In /bin/clock.sh:

#!/bin/sh
. /mnt/us/python/bin/python2.7
/mnt/us/extensions/clock/c2.py

Clock does show up as an option within KUAL, but fails to run, and the following error message is found in the KUAL log:

/tmp/klauncher_background-6670879356155924107.sh: line 2: bin/clock.sh: not found

I have tried the full path to the file and with/without double quotes.

Any ideas?
Thanks for the assistance!

Sounds like a simple path/syntax/typo kind of error. What we know for sure is that the launcher isn't seeing clock.sh for some reason.

e.g. wouldn't "./bin/clock.sh" be a better defined path?

Probably the simplest check would be to look at a few extensions from the snapshot thread and compare the path syntax there to how your script is formatted.

Are you using notepad on Windows by chance? If so, you need a text editor that supports Unix line endings. Notepad++ is good. Scripts saved with windows line endings will cause those types of issues with scripts.

I originally created the files on Windows with Notepad++, currently editing them locally on the Kindle with Leafpad. To be sure, I just recreated it with Notepad++
Tried "./bin/clock.sh" and received the same error.
Looked at the .json file for leafpad, and it's the same contents:

{
	"items": [
		{"name": "Leafpad", "priority": 1, "action": "bin/leafpad.sh"}
	]
}

Notepad++ defaults to Windows line endings. Did you switch it to Unix? Right click on the status bar near the right side. You can also set the default in Settings > Preferences > New Document.

I apologize if you already did all this...

[Junket]

That's a common stumbling block and worth checking. Windows/Dos uses "\r\n" for EOL. While *nix is just a line feed "\n" for a new line.


Notepad++ (conversion):

Notepad++ (new document format):

Another common problem happens when you have known file type extensions hidden. You can inadvertently end up with a file name like myscript.sh.txt and not realize it.

Probably would have noticed that in leafpad, however.

[handyguy]

Worth a shot, no luck. Checked Notepad++ and EOL is UNIX (greyed out from EOL conversion option)

[JimmyR]

Can you zip up your clock directory and attach it to a post? It would be easier to troubleshoot if we can see all the files in their current locations.

[handyguy]

Well, you had the right idea. menu.json was ok, but the subsequent file had the wrong EOL: clock.sh. Working now; thanks!

I would now like to add it to the Kindle home screen, but I presume that is substantially more difficult? I found this:

Kindlets have been essentially unsupported since FW 5.5.x, so, you're in for a world of pain. Booklets, on the other hand, are supported, but the API is private, and now has key bits of it obfuscated...

c.f., the hoop-jumping involved to get KUAL running almost everywhere... .

EDIT: As I can't remember whether that's specified somewhere in the docs, the repo of the mangled Booklet variant for current FWs is here: https://github.com/NiLuJe/KUAL_Booklet (it links to the main repo, so you get everything).
