So, yeah, nope, not happening ;p.

(And, on a technical level, this is why, on the K4, where I haven't found a way to detect if the device is SO, KOReader will *NOT* override the system's screensaver. On newer devices, it will on non-SO devices, but will let the Kindle deal with it on its own (i.e., show SO screensavers) on SO devices).

TL;DR: Don't Be A Dick (TM), or everybody loses.

Too many people hacked their 3G Kindles to allow unlimited 3G usage and because of this, Amazon has limited the 3G usage.

If such a patch was created and allowed, it would enable borrowing from Overdrive on your Kobo for devices where that's not enabled.

Except that it probably would also need someone to hack the Kobo servers.

No it wouldn't, but I'm not going to work on this patch, so it's pointless discussing it further.

Going to post this in this thread, hopefully it's okay.

I'd like to make some sort of daemon on top of Nickel, that listens in the background and makes Forma's up/down buttons scroll up/down in the built-in Web Browser. Where would I start with doing something like this? In particular, detecting when a button is pressed and detecting if the browser is currently running. Is there another tweak I could look at that did something similar?

Any help is welcome.

I would probably start with adapting FBInk's button_scan. First, you should work on sending drag events (although I'd first see if you can emulate them by sending key up/down/pgup/pgdown events). Then, I'd adapt button_scan to scan for the bottom toolbar of then browser, mainly the zoom bar (note that the length will be different on different devices or if you have pocket enabled. From there, you would want to patch or write a mod to prevent Kobo from seeing input events from the buttons in the web browser. Then, you can put everything together.

If you're planning on having a longer discussion on this, it would be a good idea to put it in it's own thread so posts don't get lost.

See also MiniClock's event slurper. Or evemu/evtest .

Note that, by default, you won't be able to listen to event0 (where physical buttons are sunk), but, There's A Patch For That(TM)! ;p.

About changing the Back to Home/My Books in the reading menu, which I mentioned in the patching thread: I would like to be able to change the font, since I also changed it in the header, footer and scrubber. I hope that is possible. At least, I would like to make the style normal, not bold.
Would it also be possible to change the font for the page numbers in the header and footer? It would look better if it was the same s for the book and chapter title.

I'd also like it go back home only from within a book, and not to whatever I used last.

Yes, this should be possible. Customise as you see fit and please report back.

Customise Header back label:
  - Enabled: no
  - Description: |
        Customise in-book button (top left corner) for 'Back to Home', 'Back to My Books' etc
  - FindZlib: "#ReadingMenuView"
  - ReplaceZlibGroup:
      Replacements:
        # 'Back to Home' button un-bolded
        - Find:    "#backLabel #label {\n  font-family: Avenir;\n  font-style: normal;\n  font-weight: bold;"
          Replace: "#backLabel #label {\n  font-family:Avenir;\n  font-style:normal;\n  font-weight:normal;"

@LucyOne, Ripplinger,

I tried everything I could think of to do this by customising existing nickel CSS. I came to the conclusion that the code that handles the right-hand text (page numbers, %, time remaining) must have been moved out of the nickel GUI CSS we normally use for patching. It's somewhere deeper in the firmware code. Wherever Kobo have hidden it, it's now out of my reach ... unless geek1011 has some bright ideas ...

There is a way to make the left/right halves of header/footer match but it's not a kobopatch and you may not wish to go this far.

You can do it by overriding the built-in 'Avenir Next' system font throughout the whole GUI. It requires you to:

• Choose any custom font (4 files regular, italic, bold, bolditalic)
• Use a font editor (e.g. FontForge, TTFEdit) to change the internal fontname from whatever to Avenir Next in all 4 files
• Change the external filenames to Avenir Next.ttf, Avenir Next-Italic.ttf, etc
• Sideload the 4 files to /fonts like any other sideloaded font
• Reboot the Kobo

It's still not a perfect solution because immediately after any full reboot the Kobo will use the built-in 'Avenir Next' rather than your sideloaded version. You need to force the Kobo to load it's sideloaded fonts. There are some tips in post #2 of this thread. Once your sideloaded font has been accessed it will remain available until the next reboot, i.e. it will survive Sleep mode.

It's in an ordinary string in libnickel. The fonts values are set through format strings, so there isn't any easy way to sacrifice CSS to be able to set this. It might be possible to replace them in the code (and it is possible for certain if you modify the ELF layout, but that's quite a bit more work). It might be possible to make it changeable from the CSS by assigning it a selector, though. I don't have time to look at it right now, but remind me about it next firmware version if I forget.

Thanks, jackie_w! I'll try it later. Does your patch go into nickel.yaml?

Yes, the patch does.

[LucyOne]

@jackie_w: The patch works fine, thank you! I've changed both the font weight and the font to my liking.
