I've been using ebook-meta to change the metadata on my .mobi files, and I'm trying to empty as many of the metadata slots as I can. So far I've discovered the following parameters to empty slots:
My first question is why does --publisher=" " empty the publisher slot, rather than --publisher=""? To empty the tags slot you use --tags="" - why not the same for the publisher and comments slots?
My second question is around the Book Producer slot. I can't empty this - I can't even change its content, no matter what I do. I've tried --book-producer="", --book-producer=" " and even --book-producer="test", but it remains the same no matter what. Here's sample output:
I've tried this with an old version of Calibre (0.8.something), 0.9.5 and the latest, 0.9.22. It seems to not work on any of them. Or am I doing something wrong?
Thanks for any help.
Code:
--tags=""
--publisher=" "
--comments=" "My second question is around the Book Producer slot. I can't empty this - I can't even change its content, no matter what I do. I've tried --book-producer="", --book-producer=" " and even --book-producer="test", but it remains the same no matter what. Here's sample output:
