02_config.md

The configuration file

If you want to use Crowbook for your book, this configuration file is all you'll have to add, beside the Markdown files containing the text of your book.

The format is not very complicated. This is an example of it:

# metadata
author: Joan Doe
title: Some book
lang: en

output: [html, pdf, epub]

# list of chapters
- preface.md
+ chapter_1.md
+ chapter_2.md
+ chapter_3.md
+ chapter_4.md
- epilogue.md

Basically, it is divided in two parts:

• a list of options, under the form key: value, following YAML syntax.
• a list of Markdown files.

Lines starting with the # characters are comments and are discarded.

Configuration in an inline YAML block

Sometimes, you only have one Markdown file and might not want to have a separate configuration file. In this case, you can specify options at the beginning of your Markdown file, using an inline YAML block, separated by two lines containing only ---:

---
author: Joan Doe
title: Some (short) book
lang: en

output: [html, pdf, epub]
---

# Some (short) book

The book content, formatted in Markdown.

This method only allows to set up options: you can't include a list of chapters in this way, since the only "chapter" that will be included is this Markdown file itself.

You can then use

crowbook -s some_book.md

to generate output formats from this Markdown file.

By default (unless input.yaml_blocks is set to true), Crowboook will only read those inline blocks when it is run with crowbook --single (or crowbook -s).

The list of files

There are various options to include a Markdown file.

• + file_name.md includes a numbered chapter.
• - file_name.md includes an unnumbered chapter.
• ! file_name.md includes a chapter whose title won't be displayed (except in the table of contents); this is useful for e.g. including a copyright at the beginning or the book, or for short stories where there is only one chapter.
• 42. file_name.md specifies the number for a chapter.
• @ includes a part instead of a chapter.

So a typical usage might look like this:

! copyright.md
- preface.md
0. chapter_0.md # We want to start at chapter 0 instead of 1
# Next chapters can be numbered automatically
+ chapter_1.md
+ chapter_2.md
...

There are two important things to note:

1. you must not use quotes around the file names.
2. the paths of these files are relative to the directory where your configuration file is. This means you can run crowbook books/my_trilogy/first_book/config.book without being in the book's directory.

Also note that you don't have to specify a title. This is because the title of the chapter is inferred from the Markdown document. To go back to our previous example:

+ chapter_1.md

does not specify a chapter title, because it will read it directly in chapter_1.md, e.g.:

# The day I was born #
...

Ideally, you should have one and only one level-one header (i.e. chapter title) in each Markdown file. If you have more than one, it might mess with the table of contents in some cases (e.g. for EPUB).

Parts

Parts are included using the @ character, followed by the same characters than for chapters:

@+ numbered_part.md
+ chapter_01.md
+ chapter_02.md
@- unnumbered_part.md
+ chapter_03.md
+ chapter_04.md
@42. part_with_number_42.md
+ chapter_05.md

However, you usually don't really want to have a content directly below the part, only chapters (though it can be useful to add an introduction before the first chapter of this part), so there is also a more straightforward way to use parts, using only the @ character followed by the (markdown-formatted) title of this part:

@ Beginning
+ chapter_01.md
+ chapter_02.md
@ Middle
+ chapter_03.md
+ chapter_04.md
@ Appendix
- notes.md

With this shortcut, parts are always numbered.

Subchapters

If you write your book to be rendered by crowbook, it is better to have one Markdown file per chapter. It is, however, possible to work with divisions at lower levels. In order to properly include these files, you can use the following syntax:

-- section.md
--- subsection.md
---- subsubsection.md

Note that there isn't different syntax for numbered or unnumbered sections/subsections: you can only change the numbering scheme at the chapter level.

When including those files, Crowbook will include them in the table of content as part of the previous chapter (or section for subsections, and so on). It will also adjust the header levels of the Markdown files, so, in the previous example, a level-1 header in section.md will be displayed as a level-2 header in the book, and a level-1 header in subsection.md as a level-3 header.

This can cause issues as only six levels of headers are supported; hence, if you include a level-5 header in subsubsection.md, it will cause an error.

Crowbook options

The first part of the configuration file is dedicated to pass options to Crowbook. This is YAML syntax, so each line should be of the form key: value. Note that in most cases you don't have to put string in quotes, e.g.:

title: My title

It is however possible (and sometimes necessary) to escape some characters using quotes around strings:

title: "My: title!"

It is possible to use multiline strings with >- and then indenting the lines that are part of the string:

title: >-
 A
 long
 title
author: Joan Doe

will set title to "A long title". See block literals in YAML for more information on the various way to insert multiline strings (which mostly change the way newlines will or won't be inserted).

A final note on the syntax: all options must be set before the first chapter inclusion (that is, a line beginning with +, -, x. (where x is a number) or !).

Metadata

Metadata are data about the book. Except for cover, which points to an image file, all its fields are strings. The main metadata are:

• author
• title
• subtitle
• lang, the language of the book. The unicode language code should be used, e.g. en_GB or en, fr_FR, or fr...
• cover, a path to an image file for the cover of the book (not displayed in all output formats).

There are also additional metadata:

• subject
• description
• license
• version
• date

You can define your own metadata by starting an option name with metadata.foo.

All metadata are accessible from templates, see Templates.

The import special option

The special import option allows you to include the options of another book configuration file. E.g., assuming that you want some common options to be applied to both foo.book and bar.book, you can create a common.book file:

author: Joan Doe
lang: en
license: "Copyright (C) Joan Doe. All rights reserved."

html.header: "[Joan Doe's website](http://joan-doe.com)"
tex.template: my_template.tex

You can then include this file in foo.book:

import: common.book
title: Foo

+ foo_01.md
+ foo_02.md

Or include it in bar.book, but override some of its features:

import: common.book
title: Bar
license: CC-BY-SA  # Override the license from common.book

+ bar_01.md

Output options

These options specify which files to generate.

Note that all file paths are relative to the directory where the configuration file is, not to the one where you run crowbook. So if you set:

output.epub: foo.epub

and run

$ crowbook some/dir/config.book

foo.epub will be generated in some/dir, not in your current directory.

Crowbook will try to generate each of the output.xxx files that are specified. That means that you'll have to set at least one of those if you want a call to

$ crowbook my.book

to generate anything. (It's still possible to generate a specific format, and only this one, by using the --to and --output argument on the command line).

Note that some formats depend on some commands being installed on your system. Most notably, Crowbook depends on LaTeX (xelatex by default, though you can specify another command to use with tex.command) to generate a PDF file, so PDF rendering won't work if it is not installed on your system. Crowbook also uses the zip command to generate the EPUB and ODT files.

Current output options are:

• output.html: renders a standalone HTML file.
• output.html.dir: renders a HTML directory with one page by chapter.
• output.epub: renders an EPUB file.
• output.tex: renders a LaTeX file.
• output.pdf: renders a PDF file (using tex.command).

The output option

Setting output file names manually can be a bit tedious, and is not always necessary. You can also specify a list of output formats with the output option:

output: [pdf, epub, html]

This is similar to the alternative syntax for YAML list:

output:
  - pdf
  - epub
  - html

This option will set default output path for PDF, EPUB and HTML according to the book configuration file name. So, if your book is my_book.book (or my_book.md), it will generate my_book.pdf, my_book.html and my_book.epub.

You can also infer the output file name by specifying "auto" to e.g. output.html. The previous example is thus equivalent to

output.pdf: auto
output.epub: auto
output.html: auto

output.base_path

Additionally, the output.base_path option allows you to set where the output files will be written (relatively to the book configuration file). E.g.,

output.base_path: docs/book
output.epub: book.epub

will render the EPUB file in docs/book/book.epub.

Input options

Crowbook does its best to improve the typography of your text. Default settings should be good enough for most usages, but you can enable/disable specific options:

• input.clean (default: true): if set to false, will disable all typographic "cleaning". The algorithm is dependent on the language, though currently there is only a variant implemented for fr (french), dealing with the specific non-breaking spaces rules for this language.
• input.clean.smart_quotes (default: true): if set to false, disable the "smart quote" feature, that (tries to) replace straight quotes with curly ones. As it is an heuristics and can't be perfect, you might want to disable it in some circumstances.
• input.clean.ligature_dashes (default: false): if set to true, will convert -- to en dash (–) and --- to em dash (—). This can be useful if you want to use these characters but can't access them easily on your keymap; however, as it can also cause problems if you do want to have two successive dashes, it is disabled by default.
• input.clean.ligature_guillemets (default: false): is a similar feature for french 'guillemets', replacing << and >> to « and ».

Generic options for rendering

These options allow to configure the rendering; they are used (or at least should be) for all formats.

• rendering.highlight (default: syntect): specify if and how to perform syntax highlighting for code blocks. Valid values are:
  • syntect: uses the syntect library to perform syntax highlighting. This has the advantage of also enabling syntax highlighting for LaTeX/PDF and EPUB formats; however syntect support doesn't seem to work on Windows.
  • highlight.js: this will use (and embed) highlight.js for HTML rendering, and will not perform any syntax highlighting for other output formats.
  • none: disable syntax highlighting.

If your version of crowbook (as is the case for Windows builds) isn't built with syntect support, it will default to none if you try to use it.

• rendering.highlight.theme: only used if rendering.highlight is set to syntect, selects the theme to use for syntax highlighting. Default is "InspiredGitHub". Valid theme names are:
  • "InspiredGitHub"
  • "Solarized (dark)"
  • "Solarized (light)"
  • "base16-eighties.dark"
  • "base16-mocha.dark"
  • "base16-ocean.dark"
  • and "base16-ocean.light".
• rendering.num_depth: an integer that represents the maximum level of numbering for your book. E.g., 1 will only number chapters, while 2 will number chapters, sections, but not anything below that. 6 is the maximum level and turns numbering on for all headers. (Default is 1.) This also affects what levels will be displayed in the table of contents.
• rendering.chapter and rendering.part: the strings that will be used to design chapter and part. E.g., if you want your parts to show as "Book III" instead of "Part III", you can set rendering.part: Book.
• rendering.part.roman_numerals and rendering.chapter.roman_numerals: these two booleans allow you to specify if you want roman numerals for part or chapter numbers (default is true for part numbers, and false for chapter numbers).
• rendering.inline_toc: if set to true, Crowbook will include a table of contents at the beginning of the document.
• rendering.inline_toc.name: the name of this table of contents as it should be displayed in the document.
• rendering.initials: if set to true, Crowbook will use initials, or "lettrines", displaying the first letter of each chapter bigger than the others.
• rendering.part.reset_counter: set it to false if you don't want your chapter numbers to start again at 1 at each part.

HTML Options

These options allow you to customize the HTML rendering (used both by the default HTML standalone renderer and the HTML multifile renderer):

• html.icon: allows to set a favicon for the page.
• html.header and html.footer: allow to set a custom (Markdown) string at the top and at the bottom of the HTML page. This is actually a template, so you can access metadata, such as {{{author}}}, {{{title}}}, or {{{version}}} in it. See the template chapter for more information on the fields you can use.
• html.css: allows to set up a custom CSS file. You can also redefine the colors in a file and set it using html.css.colors.
• html.css.add: allows you to add some specific lines of CSS in your book configuration file, that will be appended after the default CSS template.
• html.highlight.theme: is similar to rendering.highlight.theme but only sets the theme for HTML output.

Options for standalone HTML

There are a few options specific to the standalone HTML renderer (default, set with output.html):

• html.standalone.one_chapter: if set to true, will only display one chapter at a time (using Javascript), making it look similarly to the multifile HTML.
• html.standalone.template: allows you to change or modify the HTML template for standalone HTML.

Options for LaTeX/PDF rendering

These options allow you to customize the LaTeX renderer (and, thus, the generated PDF documents):

• tex.template: specifies a different LaTeX template.
• tex.class: changes the LaTeX class used.
• tex.paper.size and tex.font.size: (default a5paper and 10pt) allows to modify the page and font size.
• tex.margin.left, tex.margin.right, tex.margin.top and tex.margin.bottom: specify the margin of the page.
• tex.links_as_footnotes: can be set to false if you don't want links to also appear as footnotes (which means losing them if it is actually printed).
• tex.highlight.theme: similar to rendering.highlight.theme, but only sets the theme for LaTeX/PDF rendering.

Options for EPUB rendering

There are also options specific to the EPUB format:

• epub.version: can be set to 2 or 3 (default 2).
• epub.css: can be useful if you want to specify a customized stylesheet.
• epub.highlight.theme: similar to rendering.highlight.theme but only sets a theme for EPUB output.

Resources options

These options allow to embed additional files for some formats (currently, only EPUB). This can be useful for embedding fonts.

resources.files

A list of files or directories that should be added.

resources.files: [font1.otf, font2.otf]

It is also possible to specify a directory (or multiple directories). So if you have a fonts directories containing font1.otf and font2.otf,

resources.files: [fonts]

will be equivalent to:

resources.files: [fonts/font1.otf, fonts/font2.otf]

default: not set

resources.out_path

This option determine where (in which directory), in the resulting document, those files will be copied. The default is data, so by default the resources.files in the first example above will search font1.otf and font2.otf in the same directory than the .book file, and will copy them to data/font1.otf and data/font2.otf in the EPUB file. This is therefore this last path that you should use if you want to access those files e.g. in a custom CSS stylesheet.

Note that if you pass directories to resources.files, the whole directory would be copied. So assuming fonts/ contains font1.otf and font2.otf

resources.files: [fonts]
resources.path: data

will copy these two files to data/fonts/font1.otf and data/fonts/font2.otf (and not data/font1.otf and data/font2.otf).

Similarly, the whole path of resources.files is copied, so

resources.files: [fonts/font1.otf, fonts/font2.otf]

will yield the same result.

default: data

Full list of options

Here is the complete list of options. You can always look at it by running crowbook --list-options or crowbook -l.

Note that these options have a type, which in most case should be pretty straightforward (a boolean can be true or false, an integer must be composed by a number, a string is, well, any string (note that you might need to use quotes if it includes some characters that may lead the YAML parser to read it as an array, an integer or a list), and a list of strings is a list containing only strings, see YAML syntax). The path type might puzzle you a bit, but it's equivalent to a string, except Crowbook will consider it relatively to the book file. The template path type is just the path of a template. Metadata are just strings.
