Feature request: Add epub to merged epub #8

Closed potatoeggy closed 2 years ago

potatoeggy commented 2 years ago

Is there a way to add a new epub(s) to an existing epub created from EpubMerge while appending TOC entries to the end of that existing epub?

This is useful if I want to add new stories to an anthology but don't want to unmerge everything first and copy metadata over.

You can already merge using previously merged epubs. If you have the 'flatten TOC' option on, the apparent difference will be minimal.

But this has been requested enough times that I will think about how EpubMerge might include an automatic unmerge step.

For my usecase, it's not quite enough as the old anthology title appears in the TOC, and a mix of single- and multi-chapter works aren't nested as I'd like (for obvious reasons) — but it's much nicer to manually remove one TOC entry over unmerging and remerging.

Thank you!

Glad you figured something out.

FYI, if you merge previously merged epubs enough times, you will eventually bump into depth-of-directories issues based on the way epubmerge works. I don't think I tested more than maybe a dozen deep merge-of-merges.

Once in a while should be fine. But if this is something you want do every day or every week, I'd keep the original source books around to merge from (maybe in a different library). Then copy the new epub into the existing Calibre book to preserve library metadata? I'm not sure about the exact semantics of that.

One reason I hesitate to add an 'append merge' feature to EpubMerge is that it is currently completely non-destructive. You can't accidentally wreck anything because it never changes existing books, only makes new ones.
