[GUI Plugin] EpubMerge

I just got a new laptop and I'm getting an error trying to install

calibre, version 2.57.1
ERROR: Unhandled exception: <b>InvalidPlugin</b>:The plugin in u'C:\\Users\\lg***\\Downloads\\EpubMerge-master.zip' is invalid. It does not contain a top-level __init__.py file

Any guidance?
Thanks

I'm happy to take a look at the problem, but I don't see any attachments on your post.

Try again? I just checked, and it installs fine for me.

Here are the attachments (they were removed temporarily while the moderator verified that I was the actual copyright holder, which I am).

Again, the "Moment By Moment" epub displays fine and full-sized in my ibooks app. "The Clear My Mind Piano Book" epub (after merging the "Moment By Moment" epub with other epub files) displays in a reduced size.

I've also attached the metadata.opf file for "Moment By Moment".

Your original epub (from Finale) use some EPUB 3.0 features related to fixed layout and (I think) some iBooks specific extensions.

Unfortunately, EpubMerge outputs EPUB 2.0. The fixed layout settings and 'prefix' extensions aren't carried over. And EPUB 3.0 metadata layout has changed enough that it's not a simple matter to copy those settings over.

(There's been discussion again just in the last couple days about why Calibre in general doesn't support with EPUB 3.X. I don't plan to support EPUB 3 until Calibre does.)

Some details of the content.opf:

Spoiler:

Highlighted in red are parts that, if removed, cause the larger margins to appear in iBooks.

You might try seeing if Finale can output EPUB 2.0 instead of 3.0. Those might merge better.

Also, as the original copyright holder, I assume you're looking to create an omnibus ebook that you can distribute. EpubMerge is more meant for personal use. For example, EpubMerge output includes: <dc:rights>Copyrights as per source stories</dc:rights>. I won't tell you not to use it, but consider it an 'off-label' use.

[ericpaul]

Thanks for those answers. I was able to paste in those lines of code into my final document and the pages displayed properly at full size, but of course, that introduced some other errors. I can clearly see, though, that you're right, that Finale is outputting 3.0 epubs, and those codes are getting stripped out to conform to 2.0. Makes total sense.

And yes, I can try to see if Finale can output in 2.0, or perhaps I can still find a way to merge all of my individual song files within Finale, then output it directly from there. So I can see my way forward. Thanks so much!

And thanks for mentioning that epubmerge is more for personal use. I appreciate you graciously pointing that out. Thanks again, as I've been really stumped!

Thanks for this great plugin Jim..

Although I am getting a minor problem when used with your other plugin FanFicFare..
I have changed the 'Custom Columns' settings of EpubMerge to use 'Average Value from ALL Source Books'. It works okay when merging two already existing books.
But, when using 'FFF's 'Make Anthology Epub from', the specified custom column doesn't take the average value.. instead, it sums up the values.

Can this be fixed?

Epub Merge joins (EPUB) books, no columns involved. The results of the Merge is always a NEW book (entry)

FFF is a separate PI

[JimmXinu]

version365 is correct about EpubMerge.

As a convenience to the user, EpubMerge offers different options to fill the new book's custom columns from the merged books, include averaging numeric columns.

And EpubMerge's functionality is called from FanFicFare when creating anthology books from that plugin.

However, only the low-level functionality (the actual epub file level) of EpubMerge is used by FanFicFare. The higher level functionality (the custom column settings) of EpubMerge are ignored--because they're not relevant. When creating an anthology book in FanFicFare, there are no custom columns for the source epubs because they are not calibre books.

Reviewing the FanFicFare code, anthology metadata are indeed summed before assigning to int or float type custom columns. It's a FanFicFare issue, not an EpubMerge issue.

I'll think about it and see if anything brilliant springs to mind. Continued discussion should be moved to the FanFicFare thread.

[theducks]

I set it up long ago and only used the most basic of features

[JimmXinu]

It was a pretty esoteric question. :-)

Thanks for considering it..

Hello, I want to say that I love this plug-in and have never had a problem with it, until last night.

I have attached a bug report that indicates the list of range. Generally I know that this means I am trying to fill information in a place that is out of range but I can't see the problems. Maybe because I created new covers for the books? It was the first time that I did that rather than have a Calbre cover automatic download. The books look great, but now I cant merge them. Could you please take a looks and see what I need to change?

Thanks!

Since I cannot for the life of me find that "clipboard" file on the note pad, I am simply copy and paste it here.

I can't tell what the problem is with just the error message. I don't see how that could ever happen.

I'll need to also have the epub files you're trying to merge to figure to figure it out.

[Rellwood]

I'll send the epubs via pm.

[JimmXinu]

This is a new test version with a couple changes to more gracefully handle cases where the input epubs have metadata that refer to files that are missing from the zip file.

This is in response to a specific problem that has arisen with FanFicFare anthology books with sub-book covers after Calibre Polish.

UPDATE test version 2016-08-20:

- Add code for handling cover that isn't jpg. Detected by file extension.
