so i read that code, and that's fickel, not nickel. it still treats nickel as a black box - we learn a few commands we can send to nickel regarding wifi stuff, but nothing about rescanning the library or other commands we can run.

what we need is the whole source code of the frigging kobo. or at least nickel.

Did you steal your device from the store? I bought mine.

Besides, tons of companies do exactly that. Your phone (assuming it's an Android phone, like about 80% of the phones out there) probably runs free software and you can often access the source code directly, which makes it easy to hack and extend, creating this amazing ecosystem of apps. I host the source code of wallabako on a Github alternative that publishes their source code for free as well - you could host your own Gitlab instance if you wished.

So yeah, there's no reason why Kobo wouldn't publish that source code, in my opinion - they published part of it, for free too.. I also suspect that *not* releasing it may be breaking some license agreements, but i haven't looked into this in details, and I am not a lawyer so i don't wish to get into this particular endeavor right now.

But getting access to the source code would be a great way to encourage development. That, or at least providing clear specifications, documentation and APIs...

The device? Yes. The source code? No

And tons of companies don't, as the companies I've worked all my career.

I am not either but, as an application built over linux, I don't think they have to publish the code (using linux doesn't imply all your source code built over linux should be open source and distributed).

But you're mixing a SO as Android or Linux with an application. I don't think Kobo is interested in encourage development as it gives them no advantage. I doubt some people developing some apps over Kobo is going to contribute to sell a lot more of Kobo out of an environment like this (and even here).

And the companies *I* worked for most of my life publish their source code. We're hardly a relevant sample anyways...

It depends how the software is built. But you're right - if they just use the kernel, that's not a necessary condition.

I like to think people don't just do things out of their own selfish interests. Because that's the end of civilization. But then maybe that's where we're going anyways...

Anyways, this is off-topic - it'd be nice to have the source or docs, we don't have it, oh well, moving on.

I just tried the idea, and I like it. What follows is the minimal version, without testing whether there is an external sd inserted or not. In this case it is supposed that there is no external sd. I created /mnt/onboard/.mysd/ and put a book into it. Then, with nickel running, I did

Code:
(none) login: root
[root@(none) ~]# mkdir -p /mnt/onboard/.mysd
[root@(none) ~]# mount --bind /mnt/onboard/.mysd /mnt/sd
[root@(none) ~]# echo sd add /dev/mmcblk1p1 >> /tmp/nickel-hardware-status
[root@(none) ~]#
nickel reads the book from .mysd, and updates the library whenever you execute:
Code:
 echo sd add /dev/mmcblk1p1 >> /tmp/nickel-hardware-status

Hmm.. interesting. The library entry would point to /mnt/sd/yourbook.epub?

I don't have Kobo with me now, but I'll try this tomorrow.

Yes it is file:///mnt/sd/mybook.epub.

On that I agree with you, I was looking at an ereader in Spain only because they gave the source code and you could modify it.

that looks really awesome! i'll see if i can do something with this...

do we actually need to store the files in /mnt/sd for the refresh to kick in?

if we could fake remount the sd card *without* having to change anything, that would be ideal... then we could make this work for users with an sd card as well - just pretend the card was removed and put back in and we're done...

also, in my experience, just this is not sufficient:

Code:
 echo sd add /dev/mmcblk1p1 >> /tmp/nickel-hardware-status
... i guess you actually need to have that /mnt/sd mounted somehow *or* write files in there, not sure what..

With this command you make nickel only read the files that belong to the sd. Reading the whole user partition in this situation would be a waste of time and energy.

You can't use the real and virtual sd at the same time, can you?


Anyway, I tried this, and it works! I really like it! Maybe the database can be rewritten on reboot to look for the content on it's "real" place instead of the virtual sd. I tried to put a book in a subfolder and nickel had no problem with it, so one could easily do an UPDATE sql query on /mnt/sd/ebook or whatetever folder.

This way I could add any book with the hacked update server with the built-in sync.

You can try using a subdir of /mnt/sd as mount point instead of /mnt/sd itself. (It will vanish and need to be re-mounted when someone actually puts in an sd card later)

The Kobo firmware also handles multiple SD cards, identifies them by the random fat identifier... not sure what it does here with no real sd card present
