Nautilus

nautilus turns a collection of documents into a browsable ZIM file.

It downloads the video (webm or mp4 format – optionally recompress it in lower-quality, smaller size), the thumbnails, the subtitles and the authors' profile pictures ; then, it creates a static HTML files folder of it before creating a ZIM off of it.

Preparing the archive

To be used with nautilus, your archive should be a ZIP file.

• it doesn't need to be structured, but it can.
• it doesn't need to be compressed. It's usually recommended not to.
• it should contain a collection.json file, but it can also be provided separately (see below).
• it should only contain to-be-included files. No filtering is done.
• Audio and video files should be in ogg format with an .ogg/.ogv extension to be supported on all platforms (mp3/mp4 would work only on platforms with native support).

cd content/path
zip -r -0 -T ../content_name.zip *

JSON collection file

Either inside the archive ZIP as /collection.json or elsewhere, specified via --collection mycollection.json, you must supply a JSON file describing your content.

The user-interface only gives access to files referenced properly in the collection.

At the moment, the JSON file needs to provide the following fields for each item in an array:

[
    {
        "title": "...",
        "description": "...",
        "authors": "...",
        "files": ["relative/path/to/file"]
    },
    {
        "title": "...",
        "description": "...",
        "authors": "...",
        "files": [
            {
                "archive-member": "01 BOOK for printing .pdf",  // optional, member name inside archive (same as simpler format)
                "url": "http://books.com/310398120.pdf",  // optional, has precedence over `archive-member`, url to download file from
                "filename": "My book.pdf",  // optional, filename to use in ZIM, regardless of original one
            }
        ]
    }
]

About page

Either inside the archive ZIP as /about.html or elsewhere, specified via --about myabout.html,

• You may supply an about page in HTML format. It will be displayed in a modal popup and will be included.
• At its bottom your secondary-logo if provided.

• Use only content tags (no <html /> nor <head /> nor <script /> etc)
• Use inline styling if required, but no styling is recommended.
• Include one logo inline if required.

Usage

❯ nautuluszim --help
usage: nautuluszim [-h] [-V]

# everything bundled in a ZIP
nautiluszim --archive my-content.zip

# In this mode every file entry must have a valid url.
nautiluszim --collection https://example.com/to-your-collection-file

Installation

You'd want to install it in a dedicated virtual-environment (python3 -m venv some-env && source ./some-env/bin/activate)

❯ pip install nautiluszim

Contributing

❯ pip install -e .

Notes

• On macOS, the locale setting is buggy. You need to launch it with the LANGUAGE environment variable (as ISO-639-1) for the translations to work.

LANGUAGE=fr nautiluszim --language fra
