Generate EPUB and PDF from ebook-edit "folder as book"

Hello,

I am on macOS 10.14.6, learning Calibre 4.13.0.

I have extracted an EPUB for a folder and opened it with `ebook-edit`, on the command line, as follows:

`unzip -d source The_book.epub`
`ebook-edit path/to/source`

I have made changes to the files, saved the book, and I see the changes in the source files.

How do I (re)build a new EPUB and PDF file?


If I start Calibre itself, the "source" book I opened via `ebook-edit` on the command line is not in the Library, so I cannot use "Convert Book" in Calibre.

I also do not see an option in Calibre to open a "source folder" as a book, as "Edit Book" (`ebook-edit`) can do.



As background:

I am working this way so that I can keep the source files in git and make commits as I adjust them. I am editing technical material on programming, and I want to send a patch to the original author.

I found that if I open the EPUB itself (not extracted) in Calibre, then used Edit Book, I was not able to tell Calibre about extracting the EPUB files to a folder so that I could stage and commit changes. Calibre only seemed to keep the extracted files in the Cache, and only while it was running.


Thank you
