Crowbook

Render a markdown book in HTML, Epub or PDF.

Building and installing

Youl'll need to have the Rust compiler on your machine first; you can download and install it here. Once it is down:

$ cargo install crowbook

will download crowbook and install it. If this is the first time you run cargo install, you'll like

Usage

The simplest command is:

$ crowbook <BOOK>

Where BOOK is a configuration file. Crowbook will then parse the config file and generate book in HTML, Epub, LaTeX, and/or PDF, according to the setting in the configuration file.

This configuration file contains some metadata, options, and list the Markdown files. Here is a basic example:

author: Joan Doe
title: Some book
lang: en

output_html: some_book.html

+ chapter_1.md
+ chapter_2.md
+ chapter_3.md
+ ...

For more information see the configuration file, or the whole book_example directory.

It is also possible to give additional parameters to crowbook; arguments set from the command line will override the ones set in the BOOK configuration file.

USAGE:
        crowbook [FLAGS] [OPTIONS] <BOOK>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information
    -v, --verbose    Activate verbose mode

OPTIONS:
        --autoclean <BOOL>    Try to clean input markdown [values: true, false]
        --numbering <BOOL>    Number chapters or not [values: true, false]
    -o, --output <FILE>       Specify output file
    -t, --to <FORMAT>         Generate specific format [values: epub, epub, pdf, html, tex]

ARGS:
    <BOOK>    A file containing the book configuration

Command line options allow to override options defined in <BOOK> configuration file. 
E.g., even if this file specifies 'verbose: false', calling 'crowbook --verbose <BOOK>' 
will activate verbose mode.

Note that Crowbook generates output files relatively to the directory where <BOOK> is:
$ crowbook foo/bar.book --to pdf --output baz.pdf
will thus generate baz.pdf in directory foo and not in current
directory.

Features

Done

• Support for some simple format configuration files to list chapters and metadatas, so you just run crowbook some_file and you don't have to pass more options, it generates the rest.
• Support for Epub2 and Epub3 format as output.
• Support for HTML format as output.
• Partial support for LaTeX format as output, and PDF through it.
• Experimental support for Odt format as output.
• Support for basic french typography (i.e. non-breaking spaces) in HTML/Epub format.
• Some configuration for HTML/Epub templates and CSS.

ToDo

• Allow more customization.
• Support for easily embedding custom fonts (and other files) in Epub/HTML.
• Improve LaTeX and Odt generation.
• Correct support for technical books.

Acknowledgements

Besides the Rust compiler and standard library, Crowbook uses the following libraries:

• pulldown-cmark (for parsing markdown)
• mustache (for templating)
• clap (for parsing command line arguments)
• chrono (date and time library)
• uuid (to generate uuid)

While Crowbook directly doesn't use them, there was also inspiration from Pandoc and mdBook.

ChangeLog

Library

While the main purpose of Crowbook is to be runned as a command line, the code is written as a library so if you want to build on it you can use it as such. The code is currently badly documented (and badly in a general manner), but you can look at the generated documentation here.
