AcXE - ACX Enabler

This hack enables using custom ACXs (Active Content Extensions, W3C Widgets activated on text selection).

These extensions can be installed by placing to folder system/acw/ in user store or to folder /opt/amazon/acw on the system partition (this is the preferred location as the firmware can remove/recreatesystem/acw/ content any time).

See https://wiki.mobileread.com/wiki/Kindle_Touch_ACX for more information.

Everything needed for ACX signing (signing app in Java, appropriate private key) can be found here:
https://github.com/dsmid/kindle-pw2-...master/signing

Attached sample ACXs adds ability to translate selection with Google Translate to your Kindle.

Install AcXE (Update_acxe_*_install.bin from acxe_*.zip), put gtranslator.acx (the one for your device) in [userstore]/system/acw/, reboot Kindle and you should see a new "Google Translate" item in the "More" menu after you highlight some text.

Supported languages:

Spoiler:

I can add other languages if needed.

This works on PW2, PW1 and Touch.

Could you add Serbian and Croatian language to Google Translate ACX?

edit: Tested & works on PW1 fw 5.4.4 :)

Added these languages:

Code:

Ukrainian

Greek

Hebrew

Turkish

Croatian

Serbian

This does not work on the Kindle Touch (v5.3.7). I tried installing the "Update_acxe_1_install.bin" but it was deleted when I disconnected, and Update Your Kindle stayed grayed out.

Try the new version, it's repackaged to support installing on Touch.
It hasn't been tested on Touch though. Please report back to me after you test it.

Thanks! Updating now... Update is running....

The enabler hack seems to have worked -- no error message, and I now have an empty folder "/mnt/us/acxe/" :blink: is this folder necessary?

But adding gtranslator.acx at {$KindleDrive/}"system/acw/" does nothing. I should see an extra option when tapping on a word, correct? I see no changes... It hasn't overwritten the default translation acx (I didn't think it would, but checked anyway) since it still shows default languages, not your list.

I haven't tried adding it to "/opt/amazon/acw/" but I will grab kterm extension and cp it over.

...and apparently it's a read-only filesystem, so I will have to do this via USBnet?

When viewing user storage area over the usb cable, the /mnt/us portion of the filepath is suppressed.

When viewing the user storage area from the command line (ssh, telnet, serial port) then the full path is required.

I.E:
USB storage mode: /documents
Is actually (viewed from the internal system) /mnt/us/documents

I know that. :)

On my computer, it is located at "/media/Kindle/system/acw/"; note the reference to root at the beginning of "/mnt/us/system/acw/"; maybe I should've made this clearer though.

I installed AcXE on KT 5.3.7 (but not through update bundle, just by copying Upstart job and data files).

It works fine and performs bind mounts without errors. eschwartz, existence of /mnt/us/acxe/ is required by Upstart job, though, it would be nice if it would be optional (as well as debug log).

Installing gtranslator.acx gives me following log:

And as I see in stock KT 5.3.7 ACX, button priority is recognized here through <kindle:buttonPriority> element in config.xml.

So, AcXE should work fine on KT, but ACX metadata format is possibly changed in later firmwares, so it should be adapted to KT.

EDIT: BTW, uninstall.sh in source code package removes /etc/upstart/binder.conf.

/mnt/us/acxe/ serves as a flag that AcXE is installed & enabled and it also serves as a switcher - delete it, reboot and AcXE is disabled. Recreate it, reboot and AcXE is enabled again.
I consider such approach to be a good idea - at least the user will get what he/she often thinks he/she will get by resetting to factory defaults.

It should be easy to adapt gtranslator for KT by making a diff between KT translator.acx and KPW translator.acx .
Does anybody have KT translator.acx around ? (there should be a copy in [userstore]/system/acw/ )

Thanks for the report, I've fixed that in version 3.

Official 5.3.7 update bundle contains complete rootfs image.

Sure, that's just me being lazy to download the whole bundle to get a tiny file ;)
