Table of contents does not have all entries

Carlos_ER · 05-13-2013, 11:48 PM

Hi,

I'm new here.

I have a book created with LibreOffice (file.odt), which I convert to epub using Calibre.

The problem I have is that the epub, when viewed with the Calibre epub viewer, limits the table of content to 50 entries (and the same in my kobo touch reader when uploaded). After noticing this, in the conversion dialog, Table of content section, I change the number of links from the default 50 to 70, convert again, but it doesn't work.

This happens with 4 books made from the same template.

After reading the sticky here, that you want a sample file to reproduce the problem, I create a copy of the book, empty its contents, fill it again with only chapter lines (Heading 2 style), up to 60 such lines.

Like this:

Code:

Title
Author

En un lugar de La Mancha      (text body style)

Heading 1  (Heading 1 style)
01	uno  (Heading 2 style)
En un lugar de La Mancha...    (text body style)
02	dos                             (Heading 2 style)
En un lugar de La Mancha       (text body style)
...
etc
....
60	diez                            (Heading 2 style)
En un lugar de La Mancha       (text body style)

table of contents

Then I convert the file to epub... and the table of contents is correct. So I can not reproduce the problem, but still the books I want to convert are limited to 50 entries in the table of content.

Where should I look?

I'm using Calibre 0.9.30 running on Linux (openSUSE 12.1), installed directly using the instructions at http://calibre-ebook.com/download_linux.

Thanks.

Go to Preferences - Common Options - Table of Contents and change the TOC link limit from 50 to whatever you like.

Carlos_ER · 05-14-2013, 07:43 AM

Thanks!

I tried this immediately. I set the default to 70 entries.
Converted again the book, (clicked "restore to defaults on the table of contents, which changed the number to 70), and all the entries appeared on view on the resulting epub. Fantastic!

However, I did the same conversion on the 3 other similar books (same template, it is a series), and these were again trimmed to 50 entries.

I exited calibre, changed default settings to 60, tried the conversion on the second book, again trimmed at 50.

@Carlos_ER If a book has been previously converted calibre will use those settings (ie 50)

I think you will need to hit the reset default (Alt/D) on all such books

Or you can do it on multiple books - if you uncheck the check box top left then the defaults wil be applied

Good luck BR

BetterRed:

Thanks, tried Alt/D, checked that the content section says that the limit is 70, converted, viewed the file: still cut at 50. Only the first file got past the limit, the first one. The rest, no way.

kovidgoyal:

No, these files have no DRM at all. They are my own .odt files that I'm converting to .epub.

The DRM line is part of Kovid's signature. The important part of his response is the link above that.

Carlos_ER · 05-14-2013, 12:24 PM

Oh, I see! Sorry, did not notice the link.

Quote:

There are two places where conversion options can be set in calibre. The first is in Preferences->Conversion. These settings are the defaults for the conversion options. Whenever you try to convert a new book, the settings set here will be used by default.

I do not have a "Conversion" entry on the "Preferences" button. There is a "Change Calibre behaviour" entry. Then, for conversion, common options, Table of contents, there is an entry named "Number of links to add to Table of Contents" and it is set to 70.

Quote:

You can also change settings in the conversion dialog for each book conversion. When you convert a book, calibre remembers the settings you used for that book, so that if you convert it again, the saved settings for the individual book will take precedence over the defaults set in Preferences. You can restore the individual settings to defaults by using the Restore to defaults button in the individual book conversion dialog.

I did that. The dialog also says "70".

Still, the output has 50 contents entries.

Quote:

Note

You can see the actual settings used during any conversion by clicking the rotating icon in the lower right corner and then double clicking the individual conversion job. This will bring up a conversion log that will contain the actual settings used, near the top.

Ok, I did that too. The log is this:

I don't know if that tells something, but not to me. I do see an entry "'max_toc_links': 70", yet I get only 50.

Thanks for the help so far...

kovidgoyal · 05-14-2013, 12:30 PM

The reason you are getting 50 is because you are converting a document that already has a ToC and that toc has only 50 entries. Check what file you are using as input.

Carlos_ER · 05-14-2013, 01:14 PM

No, the document TOC has 59 entries. I did alt-V and counted them.
This TOC is also included as a page at the end of the epub file and it is complete.

It is the TOC that you get when you click on view table of contents in the calibre epub viewer, and in the kobo touch ereader, that contain only 50 entries.

BetterRed · 05-14-2013, 06:02 PM

Some things to try/examine in no particular order, and with no particular reasons or expectations

If you have an ORIGINAL_EPUB file then remove or move it, and try conversion again
Unpack the EPUB using Tweak Book ('T' shortcut) and look in the toc.ncx file - are there 50 or 59 entries ?
Remove the EPUB file before the conversion
Add one of the books that's giving you problems under a different title and try conversion

Have you tried the Writer2EPUB extension for Open Office - it maybe called Writer2HTML for Libre Office - then you may not have to convert in Calibre. MB member theducks uses the plugin.

Carlos_ER · 05-14-2013, 07:22 PM

Ok, I removed both ORIGINAL_EPUB and the current EPUB. Did the conversion again, and the table of contents was complete. I repeated for the two other odt files, and same result, it worked, table is complete.

As this worked, I don't know what the toc.ncx could contain, it has been erased. I can recover an older copy from the kobo touch device, though, if anyone is interested in investigating it. Or set the limit to 50, erase files, convert, back to 70 without erasing, see if the fault repeats.

As far as I'm concerned, problem is solved, thanks :-)

No need to investigate. All conversions, if there is an original_epub, will use the original as a source. As Kovid stated (and you confirmed by deleting) it had a TOC with 50 entries. It is just a typical calibre learning curve, everything worked exactly as expected.

But I don't understand.

There was an original_epub file, yes, but also there was the source .ODT file. I assumed that if I selected "convert" with changed options the conversion would be done from the original source file (the .odt), not the epub from a previous conversion with old settings.

Is there a different command to force a full conversion from the source odt with current settings, then?

But Doc, he was converting from Libre Office ODT to EPUB

The only action I know that creates an ORIGINAL_EPUB is to convert EPUB to EPUB, which I sometimes do inadvertently. I keep a beady eye on Formats in Book details and delete them when I do that.

And if Carlos_ER was converting ODT to EPUB, and he was resetting defaults then why would the existence of an ORIGINAL_EPUB have any effect.

As you say part of the learning curve.

I'd quite like to have a Tweak where I could choose to have an "Are You Sure?" question if I convert like to like, its an easy rabbit burrow to fall down.

Carlos - are you really sure that the Input Format was ODT, I'm not sure why but sometimes I find its EPUB, but I never convert from EPUB intentionally - its where I'm going not where I'm coming from.

I just looked at my preferences->behaviour. EPUB was at the top of the Preferred Input Formats, again - I'm sure I've pushed it down before, more than once in fact. Its now last! But I wouldn't bet that it wasn't me who did something to push it up to first

Anyway, your problems is solved and that's what matters most.

Good Luck BR

This TOC is also included as a page at the end of the epub file and it is complete. It is the TOC that you get when you click on view table of contents in the calibre epub viewer, and in the kobo touch ereader, that contain only 50 entries.

Did the conversion again, and the table of contents was complete. I repeated for the two other odt files, and same result, it worked, table is complete. As this worked, I don't know what the toc.ncx could contain, it has been erased. I can recover an older copy from the kobo touch device, though, if anyone is interested in investigating it. Or set the limit to 50, erase files, convert, back to 70 without erasing, see if the fault repeats. As far as I'm concerned, problem is solved, thanks :-)
