--- AutoShelf ---

Automatically create shelves/collections based on folder structure on the Kobo. This is an alternative to the collection management features in Calibre's Kobo addons.

AutoShelf runs when you unplug the reader from PC; since building the list of shelves can take some time, and applies only to books that Kobo already added to its database, running AutoShelf on disconnect is optional:

You can enable/disable it by tapping the screen while the Kobo is connected to PC.

While connected to PC, an icon will be displayed and when enabled, it will say "AUTOSHELF".

Any shelf created by this addon will end with /. So books in the root directory will be in the '/' shelf, and then there's a 'Harry Potter/' shelf - if you have a subdir for that series. Since there is no shelf-within-shelf feature (or is there?), shelves for deeper structures will end up as 'some/other/shelf/', so you get a flattened view of all subdirs.

It also sets the Series and SeriesNumber properties of books. That way you can see the folder and series number anywhere in the book list. Otherwise it will show the filename.

Note there is a chance this will corrupt your database. Make backups of your .kobo/KoboReader.sqlite.

To install, copy KoboRoot-AutoShelf.tgz » .kobo/KoboRoot.tgz

To run AutoShelf, tap the display once while the Kobo is connected to the PC. (Note it will only process books that already are in the Kobo database, so this is an additional step after copying new books on).

To customize behaviour of the addon, there is a config file in .addons/autoshelf/autoshelf.cfg [installed as autoshelf.example.cfg, to be renamed by you]

More about the config file here: https://www.mobileread.com/forums/sh...87#post3184887

To uninstall, set uninstall=1 in the config file, then run AutoShelf one more time.

Edit: Update for 4.6.9960 firmware.

Edit: Use fbink instead of pngshow to show image (no other change)

Nice! It seems to work good. Thanks.

YEAAAAAH! You are the MAN!
At this moment I'm too busy but this weekend I will try it, sure! It's a pain that there aren't sub-collections

The database corrupted too often, so in beta2 I'm using another method which seems to work better.

After pulling the USB plug, nickel will be put on hold until AutoShelf has done its work. During that time the device will appear to be stuck in the "Connected and Charged" screen. You will need to wait a few seconds (until AutoShelf has decided there is no shelf to update) or 2-3 minutes (for actually updating shelves, time depending on your number of files).

I tried displaying a progress bar at this point (like the on-animator) but unfortunately nickel does not manage to use the display properly afterwards. If someone knows how to display stuff w/o harming nickel...

You could try something like

currentRotation=$(cat /sys/class/graphics/fb0/rotate)
#write to the screen and so on
echo "$currentRotation" > /sys/class/graphics/fb0/rotate
#only now revive nickel

[frostschutz]

tshering, that is an improvement. But when I do that, nickel is turned on its head (180°) and stays that way... still it suggests it could work if one found the right rotate value that nickel needs after pickel displayed an image... I will do some more experimenting
----
It appears, what you write to rotate is the opposite of what you get:

# cat /sys/class/graphics/fb0/rotate
3
# echo 3 > /sys/class/graphics/fb0/rotate
# cat /sys/class/graphics/fb0/rotate
1
# echo 1 > /sys/class/graphics/fb0/rotate
# cat /sys/class/graphics/fb0/rotate
3

That is strange, but should be easy enough to check for and deal with.
----
This works:

currentRotation=$(cat /sys/class/graphics/fb0/rotate)
#write to the screen and so on
echo "$currentRotation" > /sys/class/graphics/fb0/rotate
cat /sys/class/graphics/fb0/rotate > /sys/class/graphics/fb0/rotate
#only now revive nickel

I'll add some progress indication in the next beta...

This is interesting. I think however one has to take into account the device model. I believe for all models apart from Aura HD and Aura H2O (and maybe Aura 6) one has to set the same value that one has read. (Edit: thinking it over again, I am not sure about Aura HD. I think you need some user feedback.)

Somehow related to this might be a problem I am having with Qt applications. When an Qt application is started on Aura HD (and I guess on H2O also) after nickel has been killed the application is rotated upside down. Next time the Qt application is started, it is showing normal, next time it is again rotated, and so on. I did this not see myself, but have from reports. I just mention it in case you find something during your investigations that could help me.

If some Kobos for some reason invert the rotation value, and others don't, my workaround should work for all because for those who don't, the additional cat rotate > rotate changes nothing. And for those who do it fixes the 180°. But that's just a theory, I don't have any other Kobo to test with.

I like it! Thanks.

I have an aura HD

As for the theory, could you please give me a hint why cat rotate > rotate does have any effect at all?

Because for some strange reason, the value you set is the opposite of the value you get. So you set $originalrotation but get its opposite; cat rotate > rotate then sets the opposite and gets $originalrotation.

Glad you like it, and thanks for the picture. I don't have paths as long as yours, so I never noticed they get cut off like that. Not sure what to do about it though. I could set a max length and then cut the left part off, but it would completely mess up the sorting.

Thank you for the answer. This seems not be the case on the Glo, for instance.

beta3 adds a progress indicator (which looks like the power on animation because I'm just using that for now), so it doesn't just hang in the "connected and charged" screen while it's working.

I still haven't figured out the book order within a shelf. And I don't want to do the obvious workaround (adding series number to author or title - it doesn't belong there).

[tshering]

Thank you for your inspiring work, Frostschutz!

I think the on-animation could be a problem on some devices, since Sergey's fmon uses this script to start (possibly several) copies of fmon.

I am using /etc/init.d/update-animator.sh for visual feedback, even if this might startle some users.

It doesn't really matter as the shelves have the same sort order options as the main library list. Plus one extra that is "Date added". That is supposedly the date added to the shelf, but it is broken in recent firmware. If you manually add four or five books to the shelf, it works, but when you restart the device, the order is wacky.
