A book build system that produces PDF, EPUB and MOBI from asciidoc to Amazon specifications.
The book source is written in Asciidoc markup and stored in the chapters folder, under a language sub-folder such as en for English. With this structure you can have multiple translations of a book developed in parallel in the same repository:
chapters/
├── en
│ ├── ChapterOne.asciidoc
│ ├── master.asciidoc
│ └── title.asciidoc
└── es
└── master.asciidoc
The master file master.asciidoc arranges all the book chapters in order, and contains attributes definitions that control the book production features.
Books are built as PDF, EPUB or MOBI using the asciidoctor, asciidoctor-pdf and asciidoctor-epub Ruby packages (https://github.com/asciidoctor). To make things easier, all the necessary packages and dependencies are included in a Docker container. You can manually install everything on your computer, or install docker and have it manage all those dependencies for you.
All the necessary dependencies to run bookbuilder are included in a docker container, which makes things a lot easier when operating bookbuilder across different operating systems. First, get docker for your operating system and install it. Ubuntu instructions are here.
Note: You don't have to use the docker container. You can install the necessary tools on your operating system directly. However, this is much more difficult as each operating system uses different installation paths and the versions and capabilities may differ. The bookbuilder Makefile is optimized to work from within the docker container.
The docker container is published on Docker Hub as merklebloom/bookbuilder. Pull the latest version like this:
sudo docker pull merklebloom/bookbuilder
Instead of pulling the docker container from docker hub, you can also build it from this repository, if you've already cloned it:
$ cd bookbuilder
$ sudo docker image build $(pwd) -t bookbuilder
Run the container, mapping the current directory (pwd = bookbuilder) to the container's /documents/ folder:
$ sudo -H docker run -it -v $(pwd):/documents/ bookbuilder
bash-4.4#
At the bash prompt, you can run the make commands, as detailed below, to build book files.
Use the make command to build a book in one of several formats. The LANG environmental variable can be used to define a language to build. If ommitted, LANG is set to en.
Syntax:
make [LANG=xx] {all,pdf,epub,kindle}
Examples:
bash-4.4# make LANG=en pdf
bash-4.4# make LANG=es epub
bash-4.4# make kindle
The resulting book files will be saved in the dist folder, with the filename composed from the book title (edit TITLE in Makefile) and the most recent commit tag. In the example below, the book TITLE is set to "TheBookTitle" and the most recent tag for the English language builds was release_example. If there are more commits since the most recent git tag, the commit ID is appended, as shown in the Spanish-language release example_tag-6-g777d9f8:
dist/
├── en
│ ├── TheBookTitle_release_example.epub
│ ├── TheBookTitle_release_example.mobi
│ └── TheBookTitle_release_example.pdf
└── es
└── TheBookTitle_example_tag-6-g777d9f8.pdf
The commit ID and tag allow you to keep track of revisions and interim releases, which helps you avoid publishing the wrong version. Not that such a mistake ever happened, ahem.
The styling and formatting is controlled by two different configuration files.
PDF books are styled by a YML-format theme file stored in conf/theme.yml. A sample with most possible settings is found in conf/theme-yml-sample. Any settings not explicitly set in conf/theme.yml will default to the built-in theme as shown in conf/theme-yml-sample. Here's a excerpt from the theme configuration file:
table_body_stripe_background_color: ffffff
table_font_family: LiberationSansNarrow
table_font_size: 10
Details about how to use the theme file are found here: https://github.com/asciidoctor/asciidoctor-pdf/blob/master/docs/theming-guide.adoc
EPUB and MOBI (Kindle) book styling is controlled by CSS files conf/epub3.css and conf/epub3-css3-only.css.
The build system (/conf, Makefile) is forked and heavily modified from https://github.com/akosma/eBook-Template, which is public domain. The Dockerfile is from https://github.com/asciidoctor/docker-asciidoctor.
