AZW3 support

[AcidWeb]

For technical reasons KCC output hybrid MOBI7+KF8 file. It already have headers like AZW3.
Calibre just never got support to edit such files correctly. And in general, it doesn't need this support - it's a pretty exotic case.

And even if KCC would output "pure" AZW3 reconverting file in Calibre would still break the file.

What do you mean? The generated mobi file is hybrid MOBI7+KF8?

It already have headers like AZW3. Calibre just never got support to edit such files correctly. And in general, it doesn't need this support - it's a pretty exotic case.

The CLI tool ebook-meta specifically exists to just edit the metadata of ebook files, including mobi, it just doesn't work.

And even if KCC would output "pure" AZW3 reconverting file in Calibre would still break the file.

Again, I would like for KCC to generate the proper AZW3 file and just edit the metadata with calibre, no reconversion necessary.

Yes. Generated file is both MOBI and AZW3 file. It just have .mobi extension.
ebook-meta don't know how to edit both sets of headers in such file.

Last time I checked (and that was years ago) tools that edited "only" metadata also deleted comic related header data. Maybe that was improved.

Also to answer your original question - this application would require major rewrite to output pure AZW3 files. It is caused by limitations of application that is used to generate the output files - kindlegen.

Alright, thank you. I'll keep looking for a solution then.

I modified kcc to accept the tag data as CLI parameter. You can find it in the PR I opened for this: #675
