Running bash scripts from Kobo browser

[pipcat]

This is a tool to run bash scripts from Kobo browser, without needing to connect to a computer.

Like khd-autopatch, script is trigered when device is connected to a usb-charger.

From Kobo browser we can write our commands to run, or load our custom scripts. With some internal javascript tricks, scripts are saved and we can plug usb-charger to force its run and see results.

See requirements and notes on readme.txt:

=========

Execute bash scripts from Kobo browser.


INSTALL:
--------

Download provided zip or create a KoboRoot.tgz with:
- /etc/udev/rules.d/99-html2bash.rules
- /usr/local/html2bash/check.sh
- /mnt/onboard/.html2bash/index.html, scripts

- Customize your own scripts editing index.html and scripts folder.
	- You can do that after install, connecting to a computer and going to /mnt/onboard/.html2bash/
	- Copy your own scripts to folder.
	- Edit index.html to modify array BASH_FILES to include your scripts.


USAGE:
------

- Open Kobo browser and go to file:///mnt/onboard/.html2bash/index.html
- Select a script or write your own.
- Press Save file and when download is done, plug Kobo device to usb-charger.
	
- To uninstall:
	- Create an empty html2bash.uninstall in root folder and plug device to usb-charger.


REQUIREMENTS:
-------------

- You need hacks "Allow download all in Browser" and "Allow launching browser without wifi connected".

- You need a usb-charger that doesn't prompt as a computer when plugged. Probably your mobile phone charger is ok.

- Launching html2bash:

Check script is launched when we plug our device to a usb-charger, but not when we plug to a computer.
I tested with a powercube 2A and a Motorola mobile charger .85A, and works nice. But some people reported different benhaviour and when they plug to usb-charger they get prompted as if connected to a computer. In this case, this method is not valid because autopatch will not be trigered, but maybe could be done similar hooking on "usb_host" rather than "usb_plug".

Samples scripts do nothing special, and are just to test, but other things could be done... ;-) For example, a script that sed Kobo eReader.conf to switch true/false on [FeatureSettings] Screenshots option, ...

Note: Only tested on Glo Hd fw 3.19.5761. Should work on other devices/fws but maybe there are differences in browser, i don't know.

It's a pity, but Kobo browser is not very much reliable ;-(
Sometimes scripts are downloaded ok and everything goes well, but sometimes there are empty downloads (0 bytes file). Sometimes browser is closed after download, sometimes not. I didn't found the reason...

Sample short scripts are downloaded ok (but not always i though) but it seems with longer scripts there are more failed downloads. For example with this script screenshots-off.sh:

Spoiler:

#!/bin/sh

# Change Screenshots=true/false in [FeatureSettings] for Kobo eReader.conf

KOBO_CONF="/mnt/onboard/.kobo/Kobo/Kobo eReader.conf"

sed 's/^Screenshots=true$/Screenshots=false/g' <"$KOBO_CONF" >"$KOBO_CONF".tmp && mv "$KOBO_CONF".tmp "$KOBO_CONF"
