[GUI Plugin] EpubSplit

[Skeeve]

Hi!

Epub Split seems to be exactly what I require!

Thanks for that.

But could you also not only show the HREF of the ToC entries, but also the text?

"part0003.html#2RHM0-e2106d65dede4aad84f56c1110acb8d1" is much less meaningfull than "Die Macht der Drei" (at least to me)

When I use it to split an epub it does show me TOC text entries (see attached).

DoctorOhh is right--EpubSplit displays both file name and TOC entry.

You might need to scroll right and resize columns. And if the entry texts are not in the TOC but instead only in the files, they will not be displayed.

The tooltip that appears when you hover over the file names will also show you the start of that chapter.

Thanks a lot to both of you.

Too bad I didn't see it

Does you EPUB have a valid NCX TOC?
Also, not all file may have TOC entries, you may need to scroll.

No idea, but scrolling helped.

I didn't understand how to automatically split into several books at once, but I managed to split one by one.

Hi,

I get the following error message when I try and split a book using EpubSplit. The ToC is working fine when I use the Edit ToC plugin. All others work fine except this one for some reason...The starter pack (box set) was received directly from an author and includes 3 books, each starting a new series.

KeyError:"There is no item names u'OEBPS/../toc.ncx' in the archive

I would greatly appreciate any help help in fixing this error so I can split this book.

Thanks,

The reference 'OEBPS/../toc.ncx' contains a superfluous path--it's the same as just 'toc.ncx'. And apparently Python's ZipFile class doesn't like that.

Fixing that particular problem isn't difficult, but it represents an entire class of problems with allowed paths: "asdf/../asdf" "asdf//asdf" "asdf/./asdf" and variations there on. Using the builtin Python method for this (os.path.normpath()) isn't directly practical because on windows it changes the '/'s to '\'s. Or '\\' in my tests, which ZipFile also doesn't like.

I'm trying to decide how much of this I want to address and how. Clearly it's not a common problem, since this is the first time it's come up in 5+ years.

In the meantime, you could edit your epub, open the content.opf file and remove "OEBPS/../". Then EpubSplit should work on it.

@JimmXinu, thanks for your help

Will removing the "OEBPS/../" from the content.opf make any changes to the file or is it unneeded code? And where do you find/access the content.opf file?

Thanks,

Use the Calibre Editor (it is down in the Misc sction), or simply U(npack) tool and a pure text editor like Notepad, then click repack (in the tool )

[Inukami]

So I removed the following line in the content.opf, but EpubSplit is still not working...

527   <item href="../toc.ncx" id="toc1" media-type="application/x-dtbncx+xml"/>

Any ideas?

Thanks,

Inukami

I believe you just edit the line, not remove it completely. Posting a screenshot of the unpacked epub in Finder or Windows Explorer would probably help with determining correct paths.

<item href="toc.ncx" id="toc1" media-type="application/x-dtbncx+xml"/>

I would try an epub to epub conversion and see if epub split works after the conversion.

Sorry. This did not work.

This worked! I converted and EpubSplit was able to open the file. Thank you for this suggestion.

Thanks to everyone for their input/suggestions. All good now.

New Test Version

It appears I'm late with a fix, but here's a test version anyway that I believe corrects addresses the issue identified.

(Turns out I had already figured it out before, I just hadn't applied it everywhere.)

I'd like it if people would test this version, both with EPUBs that had that issue and some you've split before. Feedback is appreciated.
