comicbox 1.0.0rc4

An API for reading comic archives

Comicbox

A comic book archive metadata reader and writer.

✨ Features

📚Comic Formats

Comicbox reads CBZ, CBR, CBT, and optionally PDF. Comicbox archives and writes CBZ archives and PDF metadata.

🏷️ Metadata Formats

Comicbox reads and writes:

• ComicRack Comicinfo.xml v2.1 (draft) schema,
• Comic Book Lover ComicBookInfo schema
• CoMet schema.
• PDF Metadata.
• A variety of filename schemes that encode metadata.

Usefulness

Comicbox's primary purpose is a library for use by Codex comic reader. The API isn't well documented, but you can infer what it does pretty easily here: comicbox.comic_archive as the primary interface.

The command line is increasingly useful and can read and write metadata recursively and extract pages.

Limitations and Alternatives

Comicbox does not use popular metadata database APIs or have a GUI!

Comictagger is a popular alternative. It does most of what Comicbox does but also automatically tags comics with the ComicVine API and has a desktop UI.

📦 Installation

pip install comicbox

Comicbox supports PDFs as an extra when installed like:

pip install comicbox[pdf]

Dependencies

Comicbox generally works without any binary dependencies but requires unrar be on the path to convert CBR into CBZ or extract files from CBRs.

⌨️ Usage

Console

Type

comicbox -h

see the CLI help.

Examples

comicbox test.cbz -m "{Tags: a,b,c, story_arcs: {d:1,e:'',f:3}" -m "Publisher: SmallComics" -w cr

Will write those tags to comicinfo.xml in the archive.

But it's probably better to use the --print action to see what it's going to do before you actually write to the archive:

comicbox test.cbz -m "{Tags: a,b,c, story_arcs: {d:1,e:'',f:3}" -m "Publisher: SmallComics" -p

A recursive example:

comicbox --recurse -m "publisher: SC Comics" -w cr ./SmallComicsComics/

Will recursively change the publisher to "SC Comics" for every comic found in under the SmallComicsComics directory.

Packages

Comicbox actually installs three different packages:

• comicbox The main API and CLI script.
• comicfn2dict A separate library for parsing comic filenames into dicts it also includes a CLI script.
• pdffile A utility library for reading and writing PDF files with an API like Python's ZipFile

⚙️ Config

comicbox accepts command line arguments but also an optional config file and environment variables.

The variables have defaults specified in a default yaml

The environment variables are the variable name prefixed with COMICBOX_. (e.g. COMICBOX_COMICINFOXML=0)

Log Level

change logging level:

LOGLEVEL=ERROR comicbox -p <path>

🛠 Development

You may access most development tasks from the makefile. Run make to see documentation.

🤔 Motivation

I didn't like Comictagger's API, so I built this for myself as an educational exercise and to use as a library for Codex comic reader.

📋 Schemas

Comicbox supports reading and writing several comic book metadata schemas.

Filename Schema

Comicbox includes a pretty good comic archive filename parser. It can extract a number of common fields from comic archive filenames.

Location	Name
Archive	The archive filename
Import/Export	comicbox-filename.txt

PDF Schema

The pdf metadata standard. Can be exported as an xml file or written directly to the pdf itself.

Adobe PDF Namespace Adobe PDF Standard § 14.3.3 Document Information Dictionary

PDF metadata is only read or written from and to PDF files.

Location	Name
Archive	PDF internal
Import/Export	pdf-metadata.xml

CoMet Schema

An old and uncommon comic metadata standard from a defunct comic book reader.

CoMet Specification

Location	Name
Archive	comet.xml
Import/Export	comet.xml

ComicBookInfo Schema (Comic Book Lover)

The Comic Book Lover schema. A rare but still encountered JSON schema. It probably survives because Comictagger supports writing it.

ComicBookInfo

Location	Name
Archive	Zip & Rar Comments
Import/Export	comic-book-info.json

ComicInfo Schema (Comic Rack)

The Comic Rack schema. The de facto standard of comic book metadata. The Comic Rack reader is defunct, but the Anansi Project now publishes the ComicInfo spec and has compatibly and conservatively extended it.

Anansi ComicInfo v2.1 Spec Also, an unofficial, undocumented Mylar extension to ComicInfo.xml that encodes multiple Story Arcs and Story Arc Numbers as CSV values.

Location	Name
Archive	comicinfo.xml
Import/Export	comicinfo.xml

ComicTagger Schema

The most useful comic book metadata writer is ComicTagger. It supports the ComicVine API, is extensible to other APIs, and features a nice desktop GUI. Internally, Comictagger keeps a metadata object to work with the schemas it supports. This schema allows the import and export of that schema.

Comictaggger genericmetadata.py

This schema may only be useful to developers. The author of ComicTagger offers no promises as to the stability of this API and I am very lazy, so the chances of this drifting out of date are anyone's guess. It was included because it was easy to do.

Location	Name
Archive	comictagger.json
Import/Export	comictagger.json

Comicbox Schema

The comicbox internal data structure which acts as a superset of the above schemas to allow interpolating.

Comicbox JSON Schema

JSON Format

Location	Name
Archive	comicbox.json
Import/Export	comicbox.json

YAML Format

YAML is a superset of JSON, so the JSON schema applies here.

Location	Name
Archive	comicbox.yaml
Import/Export	comicbox.yaml

CLI Format

The Comicbox CLI uses "flow style" YAML, which is an all on one line format to enter metadata on the command line.

Location	Name
Comicbox CLI	-m --metadata
Archive	comicbox-cli.yaml
Import/Export	comicbox-cli.yaml
