Groff Man Page Options

The Groff (GNU troff) man page document formats consists of plain text mixed with formatting commands that produce ASCII/UTF8 for display at the terminal. Learn more about Groff at https://www.gnu.org/software/groff/groff.html.

format: man

Title & Author

title	Document title
date	Document date
author	Author or authors of the document
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.
section	The section number in man pages.
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

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-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.

Layout

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

Formatting

adjusting	Adjusts text to the left, right, center, or both margins (l, r, c, or b).
hyphenate	Whether to hyphenate text at line breaks even in words that do not contain hyphens if it is necessary to do so to lay out words on a line without excessive spacing

Code

code-annotations

The style to use when displaying code annotations. Set this value to false to hide code annotations.

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-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.

Tables

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
footer	The footer for man pages.
header	The header for man pages.
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.

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

wrap	Determine how text is wrapped in the output (the source code, not the rendered version). auto (default): Pandoc will attempt to wrap lines to the column width specified by columns (default 72). none: Pandoc will not wrap lines at all. preserve: Pandoc will attempt to preserve the wrapping from the source document. Where there are nonsemantic newlines in the source, there will be nonsemantic newlines in the output as well.
columns	Specify length of lines in characters. This affects text wrapping in generated source code (see wrap). It also affects calculation of column widths for plain text tables. For typst, number of columns for body text.
tab-stop	Specify the number of spaces per tab (default is 4). Note that tabs within normal textual input are always converted to spaces. Tabs within code are also converted, however this can be disabled with preserve-tabs: false.
preserve-tabs	Preserve tabs within code instead of converting them to spaces. (By default, pandoc converts tabs to spaces before parsing its input.) Note that this will only affect tabs in literal code spans and code blocks. Tabs in regular text are always treated as spaces.
eol	Manually specify line endings: crlf: Use Windows line endings lf: Use macOS/Linux/UNIX line endings native (default): Use line endings appropriate to the OS on which pandoc is being run).
