[Conversion Plugin] KFX Input

[theducks]

metadata.opf is not a book.
That is the metadata backup file for Calibre.
If there is no book format, that is an 'empty book' (no formats) entry in calibre

As theducks pointed out it appears that you are trying to import the wrong file, one that is already inside of your calibre library.

See the section "Importing KFX books into calibre for conversion" in the first post in this thread for information on how to locate books downloaded using Kindle for PC.

Thanks, I was trying to find something that might be helpful.

For some reason I can see the book cover and name, but file is still unconverted KFX. Must have done something wrong. I've tried a few different books.

Duh
I figurged it out. After I get KFX I needed to convert to EPUb. I can read now.
Thanks I do appreciate your responses.

Thank you for reporting this problem. There are variations on ruby content that are not handled properly by the current version of this plugin. This will be fixed in the next plugin release, expected within a few days.

[jhowell]

Version 2.12.0 - 28 May 2024

Improve handling of ruby content. Fixes ("ruby_content xxxx has extra data: ...")

Ignore extraneous BookManifest.kfx files produced by the new Kindle for Mac app.

...that may well be related to the source files, but it's so unpredictable that I'm hesitant to assume anything. This appears in some KFX books (and, as far as I've been able to determine, only KFX books) converted to epub.

Sometimes word/phrase formatting — such as a word appearing in italics, "<i>Ibid.</i>" — is hardcoded:

<i>Ibid.</i>

and sometimes the conversion results in a style that is the format variation only, included in both the stylesheet and appearing in the text as:

<span style="class_s47">Ibid.</span>

This can result in some bizarre display glitches, but I'm more puzzled that they're unpredictable. The difference can appear in volume 2, but not volumes 1 or 3, of the same series from the same publisher released as e-books in the same month. I've seen this across multiple publishers. The only predictability is that they're consistent across the KFX (that is, it would be every appearance of italics in a given KFX source — or none of them).

Please confirm whether this is something internal to KFX's conversion routines, something that's slightly broader in Calibre's conversion routines, or something that's in the source files (such as different people doing the conversions at the publishers doing something different in InDesign or Word resulting in slightly different output code — which can/does happen). If you can, that is... and this is far from urgent. Just bizarre.

As you might expect, the Scribe update to support multiple templates per notebook presents a new use case for KFX Input. It only converts pages using initial template. Example attached.
