ePub Options

ePub is an e-book file format that is supported by many e-readers, and compatible software is available for most smartphones, tablets, and computers. You can learn more about ePub at https://en.wikipedia.org/wiki/EPUB.

format: epub

Title & Author

title	Document title
subtitle	Identifies the subtitle of the document.
date	Document date
author	Author or authors of the document
abstract	Summary of document
abstract-title	Title used to label document abstract
order	Order for document when included in a website automatic sidebar menu.

Format Options

brand	Branding information to use for this document. If a string, the path to a brand file. If false, don’t use branding on this document. If an object, an inline brand definition.
css	One or more CSS style sheets.
html-math-method	Method use to render math in HTML output (plain, webtex, gladtex, mathml, mathjax, katex). See the Pandoc documentation on Math Rendering in HTML for additional details.
html-q-tags	Use <q> tags for quotes in HTML.
quarto-required	A semver version range describing the supported quarto versions for this document or project. Examples: >= 1.1.0: Require at least quarto version 1.1 1.*: Require any quarto versions whose major version number is 1

Table of Contents

toc	Include an automatically generated table of contents (or, in the case of latex, context, docx, odt, opendocument, rst, or ms, an instruction to create one) in the output document. Note that if you are producing a PDF via ms, the table of contents will appear at the beginning of the document, before the title. If you would prefer it to be at the end of the document, use the option pdf-engine-opt: --no-toc-relocation.
toc-depth	Specify the number of section levels to include in the table of contents. The default is 3
toc-title	The title used for the table of contents.

Numbering

number-sections	Number section headings rendered output. By default, sections are not numbered. Sections with class .unnumbered will never be numbered, even if number-sections is specified.
number-depth	By default, all headings in your document create a numbered section. You customize numbering depth using the number-depth option. For example, to only number sections immediately below the chapter level, use this: number-depth: 1
number-offset	Offset for section headings in output (offsets are 0 by default) The first number is added to the section number for top-level headings, the second for second-level headings, and so on. So, for example, if you want the first top-level heading in your document to be numbered “6”, specify number-offset: 5. If your document starts with a level-2 heading which you want to be numbered “1.5”, specify number-offset: [1,4]. Implies number-sections
shift-heading-level-by	Shift heading levels by a positive or negative integer. For example, with shift-heading-level-by: -1, level 2 headings become level 1 headings, and level 3 headings become level 2 headings. Headings cannot have a level less than 1, so a heading that would be shifted below level 1 becomes a regular paragraph. Exception: with a shift of -N, a level-N heading at the beginning of the document replaces the metadata title.

ePub Options

identifier	The identifier for this publication.
creator	Creators of this publication.
contributor	Contributors to this publication.
subject	The subject of the publication.
type	Text describing the specialized type of this publication. An informative registry of specialized EPUB Publication types for use with this element is maintained in the TypesRegistry, but Authors may use any text string as a value.
format	Text describing the format of this publication.
relation	Text describing the relation of this publication.
coverage	Text describing the coverage of this publication.
rights	Text describing the rights of this publication.
belongs-to-collection	Identifies the name of a collection to which the EPUB Publication belongs.
group-position	Indicates the numeric position in which this publication belongs relative to other works belonging to the same belongs-to-collection field.
page-progression-direction	Sets the global direction in which content flows (ltr or rtl)
ibooks	iBooks specific metadata options.
epub-metadata	Look in the specified XML file for metadata for the EPUB. The file should contain a series of Dublin Core elements. For example: <dc:rights>Creative Commons</dc:rights> <dc:language>es-AR</dc:language> By default, pandoc will include the following metadata elements: <dc:title> (from the document title), <dc:creator> (from the document authors), <dc:date> (from the document date, which should be in [ISO 8601 format]), <dc:language> (from the lang variable, or, if is not set, the locale), and <dc:identifier id="BookId"> (a randomly generated UUID). Any of these may be overridden by elements in the metadata file. Note: if the source document is Markdown, a YAML metadata block in the document can be used instead.
epub-subdirectory	Specify the subdirectory in the OCF container that is to hold the EPUB-specific contents. The default is EPUB. To put the EPUB contents in the top level, use an empty string.
epub-fonts	Embed the specified fonts in the EPUB. Wildcards can also be used: for example, DejaVuSans-*.ttf. To use the embedded fonts, you will need to add declarations like the following to your CSS: @font-face { font-family: DejaVuSans; font-style: normal; font-weight: normal; src:url("DejaVuSans-Regular.ttf"); }
epub-chapter-level	Specify the heading level at which to split the EPUB into separate chapter files. The default is to split into chapters at level-1 headings. This option only affects the internal composition of the EPUB, not the way chapters and sections are displayed to users. Some readers may be slow if the chapter files are too large, so for large documents with few level-1 headings, one might want to use a chapter level of 2 or 3.
epub-cover-image	Use the specified image as the EPUB cover. It is recommended that the image be less than 1000px in width and height.
epub-title-page	If false, disables the generation of a title page.

Layout

grid	Properties of the grid system used to layout Quarto HTML pages.

Formatting

split-level

Specify the heading level at which to split the EPUB into separate chapter files. The default is to split into chapters at level-1 headings. This option only affects the internal composition of the EPUB, not the way chapters and sections are displayed to users. Some readers may be slow if the chapter files are too large, so for large documents with few level-1 headings, one might want to use a chapter level of 2 or 3.

Code

code-fold	Collapse code into an HTML <details> tag so the user can display it on-demand. true: collapse code false (default): do not collapse code show: use the <details> tag, but show the expanded code initially.
code-summary	Summary text to use for code blocks collapsed using code-fold
code-overflow	Choose how to handle code overflow, when code lines are too wide for their container. One of: scroll wrap
code-line-numbers	Include line numbers in code block output (true or false). For revealjs output only, you can also specify a string to highlight specific lines (and/or animate between sets of highlighted lines). Sets of lines are denoted with commas: 3,4,5 1,10,12 Ranges can be denoted with dashes and combined with commas: 1-3,5 5-10,12,14 Finally, animation steps are separated by |: 1-3|1-3,5 first shows 1-3, then 1-3,5 |5|5-10,12 first shows no numbering, then 5, then lines 5-10 and 12
code-copy	Enable a code copy icon for code blocks. true: Always show the icon false: Never show the icon hover (default): Show the icon when the mouse hovers over the code block
code-annotations	The style to use when displaying code annotations. Set this value to false to hide code annotations.
highlight-style	Specifies the coloring style to be used in highlighted source code. Instead of a STYLE name, a JSON file with extension .theme may be supplied. This will be parsed as a KDE syntax highlighting theme and (if valid) used as the highlighting style.
syntax-definitions	KDE language syntax definition files (XML)
indented-code-classes	Specify classes to use for all indented code blocks

Execution

Execution options should be specified within the execute key. For example:

execute:
  echo: false
  warning: false

eval	Evaluate code cells (if false just echos the code into output). true (default): evaluate code cell false: don’t evaluate code cell [...]: A list of positive or negative line numbers to selectively include or exclude lines (explicit inclusion/excusion of lines is available only when using the knitr engine)
echo	Include cell source code in rendered output. true (default in most formats): include source code in output false (default in presentation formats like beamer, revealjs, and pptx): do not include source code in output fenced: in addition to echoing, include the cell delimiter as part of the output. [...]: A list of positive or negative line numbers to selectively include or exclude lines (explicit inclusion/excusion of lines is available only when using the knitr engine)
output	Include the results of executing the code in the output. Possible values: true: Include results. false: Do not include results. asis: Treat output as raw markdown with no enclosing containers.
warning	Include warnings in rendered output.
error	Include errors in the output (note that this implies that errors executing code will not halt processing of the document).
include	Catch all for preventing any output (code or results) from being included in output.
cache	Cache results of computations (using the knitr cache for R documents, and Jupyter Cache for Jupyter documents). Note that cache invalidation is triggered by changes in chunk source code (or other cache attributes you’ve defined). true: Cache results false: Do not cache results refresh: Force a refresh of the cache even if has not been otherwise invalidated.
freeze	Control the re-use of previous computational output when rendering. true: Never recompute previously generated computational output during a global project render false (default): Recompute previously generated computational output auto: Re-compute previously generated computational output only in case their source file changes

Figures

fig-align	Figure horizontal alignment (default, left, right, or center)
fig-width	Default width for figures generated by Matplotlib or R graphics. Note that with the Jupyter engine, this option has no effect when provided at the cell level; it can only be provided with document or project metadata.
fig-height	Default height for figures generated by Matplotlib or R graphics. Note that with the Jupyter engine, this option has no effect when provided at the cell level; it can only be provided with document or project metadata.
fig-format	Default format for figures generated by Matplotlib or R graphics (retina, png, jpeg, svg, or pdf)
fig-dpi	Default DPI for figures generated by Matplotlib or R graphics. Note that with the Jupyter engine, this option has no effect when provided at the cell level; it can only be provided with document or project metadata.
fig-asp	The aspect ratio of the plot, i.e., the ratio of height/width. When fig-asp is specified, the height of a plot (the option fig-height) is calculated from fig-width * fig-asp. The fig-asp option is only available within the knitr engine.
fig-responsive	Whether to make images in this document responsive.

Tables

tbl-colwidths

Apply explicit table column widths for markdown grid tables and pipe tables that are more than columns characters wide (72 by default). Some formats (e.g. HTML) do an excellent job automatically sizing table columns and so don’t benefit much from column width specifications. Other formats (e.g. LaTeX) require table column sizes in order to correctly flow longer cell content (this is a major reason why tables > 72 columns wide are assigned explicit widths by Pandoc). This can be specified as: auto: Apply markdown table column widths except when there is a hyperlink in the table (which tends to throw off automatic calculation of column widths based on the markdown text width of cells). (auto is the default for HTML output formats) true: Always apply markdown table widths (true is the default for all non-HTML formats) false: Never apply markdown table widths. An array of numbers (e.g. [40, 30, 30]): Array of explicit width percentages.

df-print

Method used to print tables in Knitr engine documents: default: Use the default S3 method for the data frame. kable: Markdown table using the knitr::kable() function. tibble: Plain text table using the tibble package. paged: HTML table with paging for row and column overflow. The default printing method is kable.

References

bibliography	Document bibliography (BibTeX or CSL). May be a single file or a list of files
csl	Citation Style Language file to use for formatting references.
citeproc	Turn on built-in citation processing. To use this feature, you will need to have a document containing citations and a source of bibliographic data: either an external bibliography file or a list of references in the document’s YAML metadata. You can optionally also include a csl citation style file.
citation-abbreviations	JSON file containing abbreviations of journals that should be used in formatted bibliographies when form="short" is specified. The format of the file can be illustrated with an example: { "default": { "container-title": { "Lloyd's Law Reports": "Lloyd's Rep", "Estates Gazette": "EG", "Scots Law Times": "SLT" } } }

Cross-References

crossref

Configuration for cross-reference labels and prefixes. See Cross-Reference Options for more details.

Citation

citation

Citation information for the document itself specified as CSL YAML in the document front matter. For more on supported options, see Citation Metadata.

Language

lang	Identifies the main language of the document using IETF language tags (following the BCP 47 standard), such as en or en-GB. The Language subtag lookup tool can look up or verify these tags. This affects most formats, and controls hyphenation in PDF output when using LaTeX (through babel and polyglossia) or ConTeXt.
language	YAML file containing custom language translations
dir	The base script direction for the document (rtl or ltr). For bidirectional documents, native pandoc spans and divs with the dir attribute can be used to override the base direction in some output formats. This may not always be necessary if the final renderer (e.g. the browser, when generating HTML) supports the [Unicode Bidirectional Algorithm]. When using LaTeX for bidirectional documents, only the xelatex engine is fully supported (use --pdf-engine=xelatex).

Includes

include-before-body	Include contents at the beginning of the document body (e.g. after the <body> tag in HTML, or the \begin{document} command in LaTeX). A string value or an object with key “file” indicates a filename whose contents are to be included An object with key “text” indicates textual content to be included
include-after-body	Include content at the end of the document body immediately after the markdown content. While it will be included before the closing </body> tag in HTML and the \end{document} command in LaTeX, this option refers to the end of the markdown content. A string value or an object with key “file” indicates a filename whose contents are to be included An object with key “text” indicates textual content to be included
include-in-header	Include contents at the end of the header. This can be used, for example, to include special CSS or JavaScript in HTML documents. A string value or an object with key “file” indicates a filename whose contents are to be included An object with key “text” indicates textual content to be included
resources	Path (or glob) to files to publish with this document.
metadata-files	Read metadata from the supplied YAML (or JSON) files. This option can be used with every input format, but string scalars in the YAML file will always be parsed as Markdown. Generally, the input will be handled the same as in YAML metadata blocks. Values in files specified later in the list will be preferred over those specified earlier. Metadata values specified inside the document, or by using -M, overwrite values specified with this option.

Metadata

date-meta

Sets the date metadata for the document

Rendering

from	Format to read from. Extensions can be individually enabled or disabled by appending +EXTENSION or -EXTENSION to the format name (e.g. markdown+emoji).
output-file	Output file to write to
output-ext	Extension to use for generated output file
template	Use the specified file as a custom template for the generated document.
template-partials	Include the specified files as partials accessible to the template for the generated content.
filters	Specify executables or Lua scripts to be used as a filter transforming the pandoc AST after the input is parsed and before the output is written.
shortcodes	Specify Lua scripts that implement shortcode handlers
keep-md	Keep the markdown file generated by executing code
keep-ipynb	Keep the notebook file generated from executing code.
ipynb-filters	Filters to pre-process ipynb files before rendering to markdown
ipynb-shell-interactivity	Specify which nodes should be run interactively (displaying output from expressions)
plotly-connected	If true, use the “notebook_connected” plotly renderer, which downloads its dependencies from a CDN and requires an internet connection to view.
extract-media	Extract images and other media contained in or linked from the source document to the path DIR, creating it if necessary, and adjust the images references in the document so they point to the extracted files. Media are downloaded, read from the file system, or extracted from a binary container (e.g. docx), as needed. The original file paths are used if they are relative paths not containing … Otherwise filenames are constructed from the SHA1 hash of the contents.
resource-path	List of paths to search for images and other resources.
default-image-extension	Specify a default extension to use when image paths/URLs have no extension. This allows you to use the same source for formats that require different kinds of images. Currently this option only affects the Markdown and LaTeX readers.
abbreviations	Specifies a custom abbreviations file, with abbreviations one to a line. This list is used when reading Markdown input: strings found in this list will be followed by a nonbreaking space, and the period will not produce sentence-ending space in formats like LaTeX. The strings may not contain spaces.
dpi	Specify the default dpi (dots per inch) value for conversion from pixels to inch/ centimeters and vice versa. (Technically, the correct term would be ppi: pixels per inch.) The default is 96. When images contain information about dpi internally, the encoded value is used instead of the default specified by this option.
html-table-processing	If none, do not process tables in HTML input.

Text Output

ascii

Use only ASCII characters in output. Currently supported for XML and HTML formats (which use entities instead of UTF-8 when this option is selected), CommonMark, gfm, and Markdown (which use entities), roff ms (which use hexadecimal escapes), and to a limited degree LaTeX (which uses standard commands for accented characters when possible). roff man output uses ASCII by default.
