Add support for specifying target metadata in cli

[FritzHeiden]

This adds a new cli parameter to manually specify metadata to be added to the target file. The metadata is specified as follows: --metadata "title=My Comic;author=The Author"

; and = can be used in values by escaping them with \

I only tested this by converting cbz to epub and mobi.

Relates to issue #673

This works great

Why not --author --title --summary instead of parsing a long string? The parsing could cause issues and I've never seen a CLI like that.

Maybe like

• Add de-dupe cover option for landscape alignment #561

Also, is modifying ComicInfo.xml an option?

* [New arguments to CLI #561](https://github.com/ciromattia/kcc/pull/561)

I don't have a strong opinion on this. I also use comictagger, which does it like this aswell. Also, this is more flexible in case of adding more metadata fields.

Also, is modifying ComicInfo.xml an option?

It is not. While ComicInfo.xml has separate fields for series title, volume number and volume title, mobi only has title. So I combine the three fields into one, e.g.: "One Piece 1: Romance Dawn"
Without this I only get the title "Romance Dawn".

will this get merged soon?

To preface, I'm not a CLI user and don't edit metadata, so excuse me if I say anything uninformed.

I see, indeed that's how the ComicTagger CLI works. https://github.com/comictagger/comictagger/wiki/UserGuide#cli-user-guide. I'm not sure how I feel about owning parsing code however.

Is there anything wrong with naming a title like One Piece 1: Romance Dawn? Instead of just romance dawn? Because you might want to pad zeros on the volume number like v001.

I understand that author is an important field for some since it shows up in Kindle UI. @gonsanbo Do you care most about author or all the fields?

And is summary used anywhere in the Kindle UI? Maybe we could simplify with just an --author tag.

I've looked around in my Kindle and I couldn't find any mention of the summary, so honestly yeah --author tag would work great

[axu2]

@gonsanbo is there anything wrong with using comictagger or builtin kcc metadata editor to add author field?

[quantumicrowave]

I can't use the inbuilt editor because I was writing a script to automate the process but I didn't know about comictagger, I'll try using that, thanks :)

[axu2]

@gonsanbo let me know how it works, if it modifies the source file that might be problematic for some workflows and an --author tag might be really convenient.

We already have a --title tag.

[quantumicrowave]

@axu2 well I tried comictagger and its working on my script. Only disadvantage is I have to copy source files instead of hardlinking them since it edits the files, but its alright. I wouldn't mind an --author tag if it ever gets merged

Try the build in

• Adds --author argument to CLI #683

to see if it works for you.

Edit: closing for now, if you need more than author feel free to re-open.

series would be a nice addition especially when you organise your ebooks and you want them grouped together by series like One Piece, Blue Lock, Berserk ...
