[Device Plugin] Kobo Touch Extended Driver - Page 59

Check the README for this plugin, it lists what dictionaries the Kobo firmware supports. You can't add new ones, and the names and format have to be exact. The README has directions for fetching and updating hyphenation dictionaries.

I've already added the missing info to the head section of ncx

Code:

    <meta content="urn:uuid:25408827-9b20-4ef8-b63e-acb744cec453" name="dtb:uid"/>
    <meta content="1" name="dtb:depth"/>
    <meta content="0" name="dtb:totalPageCount"/>
    <meta content="0" name="dtb:maxPageNumber"/>

And it still doesn't work. I upload the fixed ebook. (It has the original_epub extension because of Calibre. But I added .zip because Mobileread doesn't allow attachments with .original_epub extension. Rename to just .epub in order to open it.)

More over when I make the epub to epub conversion inside Calibre, things go worse. Calibre now adds a cover (it's just a jpg made from cubierta.xhtml) so this new book now has nine pages instead of 8.

The page numbering now goes as follows:
1 (hidden as cover), 2, 5, 3, 7, 8, 9, 4, 6

(I also upload this re-epub. It's the .epub file in this post).

What I've seen in the calibre reconverted epub is that dtb:depth has risen to 2. Why?

@PeterT. Good hint but not the perfect one

. The relevant ncx section is

Quote:

8.4.1 Navigation Metadata

(This section is normative.)

Metadata shall be included in the head element of the NCX using the meta element. Content producers may introduce other metadata besides those listed below, if needed. However, metadata names shall not begin with the prefix "dtb:" unless defined in this standard. Players must not fail when encountering unknown metadata but must, at a minimum, ignore it.

dtb:uid
Content: The globally unique identifier for the DTB. The value is the same as that of the dc:Identifier element referenced by the unique-identifier attribute on the package file's package element. See section 3.1, "Package Identity."
Occurrence: Required
dtb:depth
Content: Positive integer indicating depth of structure of the DTB as exposed by the NCX.
Occurrence: Required
dtb:generator
Content: Name and version of software that generated the NCX.
Occurrence: Optional - recommended.
dtb:totalPageCount
Content: Non-negative integer indicating the number of pageTargets in the pageList. If there are no navigable pages, then dtb:totalPageCount must have a value of zero.
Occurrence: Required
dtb:maxPageNumber
Content: Non-negative integer indicating the largest value attribute on pageTarget in the pageList. If there are no navigable pages, then dtb:maxPageNumber must have a value of zero.
Occurrence: Required

Because an issue about KTE plugin has been discarded by jgoguen, I've opened a new dedicated thread in the Kobo forum.

This is NOT a fault of the extended driver. It is a problem in the firmware. If you simply copy the epub to the device, change the extension to ".kepub.epub", you will see exactly the same problem.

And you are using an undocumented and unsupported feature of the firmware. The full book page numbers for kepubs is not supported by Kobo. The way of turning it on has been found by looking at executables in the firmware. Problems like your are seeing explain why Kobo haven't made it an option in the GUI.

The fix is simple. Either turn the unsupported option off or create a TOC entry for each file in the book.

And inaccurate on a good day even in the RMSDK reader that fully supports this method of page numbering

Yes I know that RMSDK page numbering (or nearly any kind of page numbering in an ebook) is inaccurate, but at least it doesn't leap like a mad frog...

If there's nothing wrong with the epub, now I do understand why Kobo uses only page numbers relative to each chapter...

But it's somehow quite sad that they cannot get a normal numbering work in a normal way, (even if inaccurate or artificial). So they are forced to use only chapter pages.

(I still hope that there's some kind of bug inside the epub, not in the ACCESS renderer. Why, if you know the pages of each chapter, just ADD them up and you have the total pages of the ebook. Then, when switching chapters, add the total number of pages from the previous chapters to your current 1, 2, 3... Is that so difficult to code and make it work flawless?).

Yes it is on a low power device. To use per chapter page numbering, you render the current chapter and calculate the numbers. When the user changes the font, font size, margins or line spacing, you rerender and recalculate the page numbers.

To do full page numbering, you need to render the complete book. And re-render each time the settings are changed. For a short book, that will be OK. But, for a long book (think all of Lord of the Rings in one book), that could take some time. And the devices have limited RAM, so t might not even be possible.

Full book page numbering with epubs and the RMSDK is only possible because it calculates the number of pages based on the compressed size of the files. They are independent of the reader settings.

Overall, I think this is a bug in the ACCESS renderer. But, it might be something missing in the book. Remember, we are talking about kepubs, not epubs. They don't have to follow the same rules. And we don't actually know the full specs for kepubs. Maybe to be a valid kepub, it must have a TOC entry for each file. If that is the case, the bug in the firmware is that it displays the book at all.

@davidfor. We are cannibalizing jgoguen thread with a philosophical discussion which I DO really like, but maybe the owner of the thread doesn't...

I answer you in the thread I opened in the Kobo section of the forums.

For various reasons, I did a factory reset on my Aura HD, and now whenever I try to copy any book I get the same error. These are all books I have uploaded before.

-----
calibre, version 1.12.0
ERROR: Error: Error communicating with device

My settings are shown below. I also get the same failuers if I turn off Modify CSS, smarten punctuations and hyphenate files. Any ideas about what I might be doing wrong would be appreciated.

Thanks.

A second issue I keep having is with collections. Not only are empty collections not being removed, but every collection I have ever had keeps being recreated, even if I don't have any books in it now. I just reset my device to factory defaults, and the first time I synced one book, every old collection came back.

Any ideas as to what might be causing this, or where the collections names are being stored on my Mac. Is there some file I can delete to at least get back to the start state.

Thanks.

davidfor · 11-23-2013, 02:52 AM

If you did a factory reset, any shelves that were synced to the Kobo server will be recreated during the set-up. As the shelf state of sideloaded books is not synced, then a lot of empty shelves will be recreated during the set-up. And there has been a bug that seems to be on the server side where deleted shelves are recreated. I don't know it that has been fixed or not. But, I did a factory reset last week on my Glo and they didn't appear.

The driver should be removing empty shelves as long as the options are set correctly. Could you run calibre in debug mode, connect the device and then post the debug log? I can look through it and hopefully see what is going on.

Happy to try. 2 questions? How does one run calibre in debug mode and where do I find the log?

For some reason I was thinking you would know, so was lazy

To run calibre in debug mode, right-click the preferences button and choose "Restart in debug mode". Calibre will restart. Connect the ereader and let calibre do it stuff. When the jobs have finished and calibre shows the books that are on the device, close calibre and post the displayed log. Or send it to me in PM.

Is the Lovecraft book a free download from somewhere?

The first is what you have to do because you left old versions installed for so long. The second is how you prevent this from happening again.

OK, thanks. Took me some time to get to this, and was loath to try it because of the customizations I made in calibre, but as it turns out all my settings for the extended driver were still intact. Hurray!
I shall try to endeavor to keep my plugins updated
