[GUI Plugin] EpubMerge

[JimmXinu]

Oops. First/Last source book and series number should all be working now. Updated on the earlier post.

Perfect, thanks!

[JimmXinu]

Excellent. Thanks for testing. 1.0.1 is now the default version.

This is a fantastic resource - thank you for sharing it! I've been trying to use the Calibre plugin, but I'm running into a problem after I enter the metadata:

Spoiler:

calibre, version 0.8.40
ERROR: Unhandled exception: <b>AttributeError</b>:'NoneType' object has no attribute 'data'

Traceback (most recent call last):
File "calibre_plugins.epubmerge.dialogs", line 82, in do_loop
File "calibre_plugins.epubmerge.dialogs", line 91, in do_when_finished
File "calibre_plugins.epubmerge.epubmerge_plugin", line 365, in _start_merge
File "calibre_plugins.epubmerge.epubmerge", line 199, in doMerge
AttributeError: 'NoneType' object has no attribute 'data'

Am I leaving something blank that must be entered in order for the conversion to work? Is it perhaps caused by the individual epubs?

[JimmXinu]

@ScottM - one of your input epubs doesn't have a title (dc:title) tag. In the next version, I'll change it to ignore missing titles.

In the mean time, there's a number of ways you could fix that, one of the easiest is to use the Modify Epub plugin's 'Update Metadata' feature on all the epubs you're trying to merge.

[ScottM]

Worked like a charm - much obliged!

[JimmXinu]

v1.0.2 released with improved handling of epubs with missing title and/or author.

If you get "(Title Missing)" or "(Author Missing)", use Modify Epub plugin's 'Update Metadata' feature or other epub editing tool to fix the input epubs.

I'm having problems trying to use the EPub Merge plug-in. I keep getting this error message:

calibre, version 0.8.46
ERROR: Unhandled exception: <b>AttributeError</b>:'NoneType' object has no attribute 'data'

Traceback (most recent call last):
File "calibre_plugins.epubmerge.dialogs", line 82, in do_loop

AttributeError: 'NoneType' object has no attribute 'data'

This seems to be similar to the error message posted above. I tried editing the title and author metadata, but no luck. I'm not sure what I'm doing wrong?

[JimmXinu]

@cczichray - I believe one (or more) of your input epubs has an empty author (dc:creator) tag. In the next version, I'll change it to ignore empty authors--I addressed *missing* authors in the previous version along with missing title, but not empty.

In the mean time, there's a number of ways you could fix that, one of the easiest is to use the Modify Epub plugin's 'Update Metadata' feature on all the epubs you're trying to merge.

[JimmXinu]

v1.0.3 released with improved handling of epubs with present, but empty author.

If you get "(Title Missing)" or "(Author Missing)", use Modify Epub plugin's 'Update Metadata' feature or other epub editing tool to fix the input epubs.

Registered here just to say: Thanks! Finally an easy way to combine epubs!!

[JimmXinu]

@samhandwich - You're quite welcome.

[cczichray]

JimmXinu, thank you so much for your reply! I was able to get everything merged.

My new problem is with the images in my epub files. After merging, my new epub file does not contain the images from the original files. I tried dropping the files into the Images folder, but this did not work.

Has anyone else had a similar issue?

[JimmXinu]

@cczichray - Can you post one of the source epubs with images here? Preferably a small one? And/or one of the output epubs?

[cczichray]

Here is one of the original epub files and the merged epub file. This was just a test, so things look pretty rough!
