Gutenberg Offline

This scraper downloads the whole Project Gutenberg library and puts it in a ZIM file, a clean and user friendly format for storing content for offline usage.

Coding guidelines

Main coding guidelines comes from the openZIM Wiki

Setting up the environment

Here we will setup everything needed to run the source version from your machine, supposing you want to modify it. If you simply want to run the tool, you should either install the PyPi package or use the Docker image. Docker image can also be used for development but needs a bit of tweaking for live reload of your code modifications.

Install the dependencies

First, ensure you use the proper Python version, inline with the requirement of pyproject.toml (you might for instance use pyenv to manage multiple Python versions in parallel).

You then need to install the various tools/libraries needed by the scraper.

GNU/Linux

sudo apt-get install python-pip python-dev libxml2-dev libxslt-dev advancecomp jpegoptim pngquant p7zip-full gifsicle curl zip zim-tools

macOS

brew install advancecomp jpegoptim pngquant p7zip gifsicle

Setup the package

First, clone this repository.

git clone git@github.com:kiwix/gutenberg.git
cd gutenberg

If you do not already have it on your system, install hatch to build the software and manage virtual environments (you might be interested by our detailed Developer Setup as well).

pip3 install hatch

Start a hatch shell: this will install software including dependencies in an isolated virtual environment.

hatch shell

That's it. You can now run gutenberg2zim from your terminal.

Getting started

After setting up the whole environment you can just run the main script gutenberg2zim. It will download, process and export the content.

./gutenberg2zim

Arguments

You can also specify parameters to customize the content. Only want books with the Id 100-200? Books only in French? English? Or only those both? No problem! You can also include or exclude book formats. You can add bookshelves and the option to search books by title to enrich your user experince.

./gutenberg2zim -l en,fr -f pdf --books 100-200 --bookshelves --title-search

This will download books in English and French that have the Id 100 to 200 in the HTML (default) and PDF format.
