title: Pandoc User's Guide
author: John MacFarlane
date: November 19, 2020

# Synopsis
`pandoc` [*options*] [*input-file*]...
# Description
Pandoc is a [Haskell] library for converting from one markup format to
another, and a command-line tool that uses this library.
Pandoc can convert between numerous markup and word processing formats,
including, but not limited to, various flavors of [Markdown], [HTML],
[LaTeX] and [Word docx]. For the full lists of input and output formats,
see the `--from` and `--to` [options below][General options].
Pandoc can also produce [PDF] output: see [creating a PDF], below.
Pandoc's enhanced version of Markdown includes syntax for [tables],
[definition lists], [metadata blocks], [footnotes], [citations], [math],
and much more. See below under [Pandoc's Markdown].
Pandoc has a modular design: it consists of a set of readers, which parse
text in a given format and produce a native representation of the document
(an _abstract syntax tree_ or AST), and a set of writers, which convert
this native representation into a target format. Thus, adding an input
or output format requires only adding a reader or writer. Users can also
run custom [pandoc filters] to modify the intermediate AST.
Because pandoc's intermediate representation of a document is less
expressive than many of the formats it converts between, one should
not expect perfect conversions between every format and every other.
Pandoc attempts to preserve the structural elements of a document, but
not formatting details such as margin size. And some document elements,
such as complex tables, may not fit into pandoc's simple document
model. While conversions from pandoc's Markdown to all formats aspire
to be perfect, conversions from formats more expressive than pandoc's
Markdown can be expected to be lossy.
## Using pandoc
If no *input-files* are specified, input is read from *stdin*.
Output goes to *stdout* by default. For output to a file,
use the `-o` option:
pandoc -o output.html input.txt
By default, pandoc produces a document fragment. To produce a standalone
document (e.g. a valid HTML file including `<head>` and `<body>`),
use the `-s` or `--standalone` flag:
pandoc -s -o output.html input.txt
For more information on how standalone documents are produced, see
[Templates] below.
If multiple input files are given, `pandoc` will concatenate them all (with
blank lines between them) before parsing. (Use `--file-scope` to parse files
individually.)
## Specifying formats
The format of the input and output can be specified explicitly using
command-line options. The input format can be specified using the
`-f/--from` option, the output format using the `-t/--to` option.
Thus, to convert `hello.txt` from Markdown to LaTeX, you could type:
pandoc -f markdown -t latex hello.txt
To convert `hello.html` from HTML to Markdown:
pandoc -f html -t markdown hello.html
Supported input and output formats are listed below under [Options]
(see `-f` for input formats and `-t` for output formats). You
can also use `pandoc --list-input-formats` and
`pandoc --list-output-formats` to print lists of supported
formats.
If the input or output format is not specified explicitly, `pandoc`
will attempt to guess it from the extensions of the filenames.
Thus, for example,
pandoc -o hello.tex hello.txt
will convert `hello.txt` from Markdown to LaTeX. If no output file
is specified (so that output goes to *stdout*), or if the output file's
extension is unknown, the output format will default to HTML.
If no input file is specified (so that input comes from *stdin*), or
if the input files' extensions are unknown, the input format will
be assumed to be Markdown.
## Character encoding
Pandoc uses the UTF-8 character encoding for both input and output.
If your local character encoding is not UTF-8, you
should pipe input and output through [`iconv`]:
iconv -t utf-8 input.txt | pandoc | iconv -f utf-8
Note that in some output formats (such as HTML, LaTeX, ConTeXt,
RTF, OPML, DocBook, and Texinfo), information about
the character encoding is included in the document header, which
will only be included if you use the `-s/--standalone` option.
[`iconv`]: https://www.gnu.org/software/libiconv/
## Creating a PDF
To produce a PDF, specify an output file with a `.pdf` extension:
pandoc test.txt -o test.pdf
By default, pandoc will use LaTeX to create the PDF, which requires
that a LaTeX engine be installed (see `--pdf-engine` below).
Alternatively, pandoc can use ConTeXt, roff ms, or HTML as an
intermediate format. To do this, specify an output file with a
`.pdf` extension, as before, but add the `--pdf-engine` option
or `-t context`, `-t html`, or `-t ms` to the command line.
The tool used to generate the PDF from the intermediate format
may be specified using `--pdf-engine`.
You can control the PDF style using variables, depending on
the intermediate format used: see [variables for LaTeX],
[variables for ConTeXt], [variables for `wkhtmltopdf`],
[variables for ms]. When HTML is used as an intermediate
format, the output can be styled using `--css`.
To debug the PDF creation, it can be useful to look at the intermediate
representation: instead of `-o test.pdf`, use for example `-s -o test.tex`
to output the generated LaTeX. You can then test it with `pdflatex test.tex`.
When using LaTeX, the following packages need to be available
(they are included with all recent versions of [TeX Live]):
[`amsfonts`], [`amsmath`], [`lm`], [`unicode-math`],
[`ifxetex`], [`ifluatex`], [`listings`] (if the
`--listings` option is used), [`fancyvrb`], [`longtable`],
[`booktabs`], [`graphicx`] (if the document
contains images), [`hyperref`], [`xcolor`],
[`ulem`], [`geometry`] (with the `geometry` variable set),
[`setspace`] (with `linestretch`), and
[`babel`] (with `lang`). The use of `xelatex` or `lualatex` as
the PDF engine requires [`fontspec`]. `lualatex` uses
[`selnolig`]. `xelatex` uses [`polyglossia`] (with `lang`),
[`xecjk`], and [`bidi`] (with the `dir` variable set). If the
`mathspec` variable is set, `xelatex` will use [`mathspec`]
instead of [`unicode-math`]. The [`upquote`] and [`microtype`]
packages are used if available, and [`csquotes`] will be used
for [typography] if the `csquotes` variable or metadata field is
set to a true value. The [`natbib`], [`biblatex`], [`bibtex`],
and [`biber`] packages can optionally be used for [citation
rendering]. The following packages will be used to improve
output quality if present, but pandoc does not require them to
be present: [`upquote`] (for straight quotes in verbatim
environments), [`microtype`] (for better spacing adjustments),
[`parskip`] (for better inter-paragraph spaces), [`xurl`] (for
better line breaks in URLs), [`bookmark`] (for better PDF
bookmarks), and [`footnotehyper`] or [`footnote`] (to allow
footnotes in tables).

## Reading from the Web
Instead of an input file, an absolute URI may be given. In this case
pandoc will fetch the content using HTTP:
pandoc -f html -t markdown https://www.fsf.org
It is possible to supply a custom User-Agent string or other
header when requesting a document from a URL:
pandoc -f html -t markdown --request-header User-Agent:"Mozilla/5.0" \
https://www.fsf.org

:::
Note that `odt`, `docx`, `epub`, and `pdf` output will not be directed
to *stdout* unless forced with `-o -`.
Extensions can be individually enabled or
disabled by appending `+EXTENSION` or `-EXTENSION` to the format
name. See [Extensions] below, for a list of extensions and their
names. See `--list-output-formats` and `--list-extensions`, below.
`-o` *FILE*, `--output=`*FILE*
: Write output to *FILE* instead of *stdout*. If *FILE* is
`-`, output will go to *stdout*, even if a non-textual format
(`docx`, `odt`, `epub2`, `epub3`) is specified.
`--data-dir=`*DIRECTORY*
: Specify the user data directory to search for pandoc data files.
If this option is not specified, the default user data directory
will be used. On \*nix and macOS systems this will be the `pandoc`
subdirectory of the XDG data directory (by default,
`$HOME/.local/share`, overridable by setting the `XDG_DATA_HOME`
environment variable). If that directory does not exist,
`$HOME/.pandoc` will be used (for backwards compatibility).
In Windows the default user data directory is
`C:\Users\USERNAME\AppData\Roaming\pandoc`.
You can find the default user data directory on your system by
looking at the output of `pandoc --version`.
A `reference.odt`, `reference.docx`, `epub.css`, `templates`,
`slidy`, `slideous`, or `s5` directory
placed in this directory will override pandoc's normal defaults.
`-d` *FILE*, `--defaults=`*FILE*
: Specify a set of default option settings. *FILE* is a YAML
file whose fields correspond to command-line option
settings. All options for document conversion, including input
and output files, can be set using a defaults file. The file will
be searched for first in the working directory, and then in
the `defaults` subdirectory of the user data directory
(see `--data-dir`). The `.yaml` extension may be omitted.
See the section [Default files] for more information on the
file format. Settings from the defaults file may be
overridden or extended by subsequent options on the command
line.
`--bash-completion`
: Generate a bash completion script. To enable bash completion
with pandoc, add this to your `.bashrc`:
eval "$(pandoc --bash-completion)"
`--verbose`
: Give verbose debugging output.
`--quiet`
: Suppress warning messages.
`--fail-if-warnings`
: Exit with error status if there are any warnings.
`--log=`*FILE*
: Write log messages in machine-readable JSON format to
*FILE*. All messages above DEBUG level will be written,
regardless of verbosity settings (`--verbose`, `--quiet`).
`--list-input-formats`
: List supported input formats, one per line.
`--list-output-formats`
: List supported output formats, one per line.
`--list-extensions`[`=`*FORMAT*]
: List supported extensions for *FORMAT*, one per line, preceded
by a `+` or `-` indicating whether it is enabled by default
in *FORMAT*. If *FORMAT* is not specified, defaults for
pandoc's Markdown are given.
`--list-highlight-languages`
: List supported languages for syntax highlighting, one per
line.
`--list-highlight-styles`
: List supported styles for syntax highlighting, one per line.
See `--highlight-style`.
`-v`, `--version`
: Print version.
`-h`, `--help`
: Show usage message.

## Reader options {.options}
`--shift-heading-level-by=`*NUMBER*
: 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. `--shift-heading-level-by=-1`
is a good choice when converting HTML or Markdown documents that
use an initial level-1 heading for the document title and
level-2+ headings for sections. `--shift-heading-level-by=1`
may be a good choice for converting Markdown documents that
use level-1 headings for sections to HTML, since pandoc uses
a level-1 heading to render the document title.
`--base-header-level=`*NUMBER*
: *Deprecated. Use `--shift-heading-level-by`=X instead,
where X = NUMBER - 1.* Specify the base level for headings
(defaults to 1).
`--strip-empty-paragraphs`
: *Deprecated. Use the `+empty_paragraphs` extension instead.*
Ignore paragraphs with no content. This option is useful
for converting word processing documents where users have
used empty paragraphs to create inter-paragraph space.
`--indented-code-classes=`*CLASSES*
: Specify classes to use for indented code blocks--for example,
`perl,numberLines` or `haskell`. Multiple classes may be separated
by spaces or commas.
`--default-image-extension=`*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.
`--file-scope`
: Parse each file individually before combining for multifile
documents. This will allow footnotes in different files with the
same identifiers to work as expected. If this option is set,
footnotes and links will not work across files. Reading binary
files (docx, odt, epub) implies `--file-scope`.
`-F` *PROGRAM*, `--filter=`*PROGRAM*
: Specify an executable to be used as a filter transforming the
pandoc AST after the input is parsed and before the output is
written. The executable should read JSON from stdin and write
JSON to stdout. The JSON must be formatted like pandoc's own
JSON input and output. The name of the output format will be
passed to the filter as the first argument. Hence,
pandoc --filter ./caps.py -t latex
is equivalent to
pandoc -t json | ./caps.py latex | pandoc -f json -t latex
The latter form may be useful for debugging filters.
Filters may be written in any language. `Text.Pandoc.JSON`
exports `toJSONFilter` to facilitate writing filters in Haskell.
Those who would prefer to write filters in python can use the
module [`pandocfilters`], installable from PyPI. There are also
pandoc filter libraries in [PHP], [perl], and
[JavaScript/node.js].
In order of preference, pandoc will look for filters in
1. a specified full or relative path (executable or
non-executable)
2. `$DATADIR/filters` (executable or non-executable)
where `$DATADIR` is the user data directory (see
`--data-dir`, above).
3. `$PATH` (executable only)
Filters and Lua-filters are applied in the order specified
on the command line.
`-L` *SCRIPT*, `--lua-filter=`*SCRIPT*
: Transform the document in a similar fashion as JSON filters (see
`--filter`), but use pandoc's built-in Lua filtering system. The given
Lua script is expected to return a list of Lua filters which will be
applied in order. Each Lua filter must contain element-transforming
functions indexed by the name of the AST element on which the filter
function should be applied.
The `pandoc` Lua module provides helper functions for element
creation. It is always loaded into the script's Lua environment.
The following is an example Lua script for macro-expansion:
function expand_hello_world(inline)
if inline.c == '{{helloworld}}' then
return pandoc.Emph{ pandoc.Str "Hello, World" }
else
return inline
end
end
return {{Str = expand_hello_world}}
In order of preference, pandoc will look for Lua filters in
1. a specified full or relative path (executable or
non-executable)
2. `$DATADIR/filters` (executable or non-executable)
where `$DATADIR` is the user data directory (see
`--data-dir`, above).
`-M` *KEY*[`=`*VAL*], `--metadata=`*KEY*[`:`*VAL*]
: Set the metadata field *KEY* to the value *VAL*. A value specified
on the command line overrides a value specified in the document
using [YAML metadata blocks][Extension: `yaml_metadata_block`].
Values will be parsed as YAML boolean or string values. If no value is
specified, the value will be treated as Boolean true. Like
`--variable`, `--metadata` causes template variables to be set.
But unlike `--variable`, `--metadata` affects the metadata of the
underlying document (which is accessible from filters and may be
printed in some output formats) and metadata values will be escaped
when inserted into the template.
`--metadata-file=`*FILE*
: Read metadata from the supplied YAML (or JSON) file. 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][Extension: `yaml_metadata_block`]. This option can be
used repeatedly to include multiple metadata files; values in
files specified later on the command line will be preferred
over those specified in earlier files. Metadata values
specified inside the document, or by using `-M`, overwrite
values specified with this option.
`-p`, `--preserve-tabs`
: Preserve tabs 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.
`--tab-stop=`*NUMBER*
: Specify the number of spaces per tab (default is 4).
`--track-changes=accept`|`reject`|`all`
: Specifies what to do with insertions, deletions, and comments
produced by the MS Word "Track Changes" feature. `accept` (the
default) processes all the insertions and deletions.
`reject` ignores them. Both `accept` and `reject` ignore comments.
`all` includes all insertions, deletions, and comments, wrapped
in spans with `insertion`, `deletion`, `comment-start`, and
`comment-end` classes, respectively. The author and time of
change is included. `all` is useful for scripting: only
accepting changes from a certain reviewer, say, or before a
certain date. If a paragraph is inserted or deleted,
`track-changes=all` produces a span with the class
`paragraph-insertion`/`paragraph-deletion` before the
affected paragraph break. This option only affects the docx
reader.
`--extract-media=`*DIR*
: 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. If the source format is
a binary container (docx, epub, or odt), the media is
extracted from the container and the original
filenames are used. Otherwise the media is read from the
file system or downloaded, and new filenames are constructed
based on SHA1 hashes of the contents.
`--abbreviations=`*FILE*
: Specifies a custom abbreviations file, with abbreviations
one to a line. If this option is not specified, pandoc will
read the data file `abbreviations` from the user data
directory or fall back on a system default. To see the
system default, use
`pandoc --print-default-data-file=abbreviations`. The only
use pandoc makes of this list is in the Markdown reader.
Strings ending in a period that are found in this list will
be followed by a nonbreaking space, so that the period will
not produce sentence-ending space in formats like LaTeX.

## General writer options {.options}
`-s`, `--standalone`
: Produce output with an appropriate header and footer (e.g. a
standalone HTML, LaTeX, TEI, or RTF file, not a fragment). This option
is set automatically for `pdf`, `epub`, `epub3`, `fb2`, `docx`, and `odt`
output. For `native` output, this option causes metadata to
be included; otherwise, metadata is suppressed.
`--template=`*FILE*|*URL*
: Use the specified file as a custom template for the generated document.
Implies `--standalone`. See [Templates], below, for a description
of template syntax. If no extension is specified, an extension
corresponding to the writer will be added, so that `--template=special`
looks for `special.html` for HTML output. If the template is not
found, pandoc will search for it in the `templates` subdirectory of
the user data directory (see `--data-dir`). If this option is not used,
a default template appropriate for the output format will be used (see
`-D/--print-default-template`).
`-V` *KEY*[`=`*VAL*], `--variable=`*KEY*[`:`*VAL*]
: Set the template variable *KEY* to the value *VAL* when rendering the
document in standalone mode. If no *VAL* is specified, the
key will be given the value `true`.
`-D` *FORMAT*, `--print-default-template=`*FORMAT*
: Print the system default template for an output *FORMAT*. (See `-t`
for a list of possible *FORMAT*s.) Templates in the user data
directory are ignored. This option may be used with
`-o`/`--output` to redirect output to a file, but
`-o`/`--output` must come before `--print-default-template`
on the command line.
Note that some of the default templates use partials, for
example `styles.html`. To print the partials, use
`--print-default-data-file`: for example,
`--print-default-data-file=templates/styles.html`.
`--print-default-data-file=`*FILE*
: Print a system default data file. Files in the user data directory
are ignored. This option may be used with `-o`/`--output` to
redirect output to a file, but `-o`/`--output` must come before
`--print-default-data-file` on the command line.
`--eol=crlf`|`lf`|`native`
: Manually specify line endings: `crlf` (Windows), `lf`
(macOS/Linux/UNIX), or `native` (line endings appropriate
to the OS on which pandoc is being run). The default is
`native`.
`--dpi`=*NUMBER*
: 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 96dpi. When images contain information about dpi
internally, the encoded value is used instead of the default
specified by this option.
`--wrap=auto`|`none`|`preserve`
: Determine how text is wrapped in the output (the source
code, not the rendered version). With `auto` (the default),
pandoc will attempt to wrap lines to the column width specified by
`--columns` (default 72). With `none`, pandoc will not wrap
lines at all. With `preserve`, pandoc will attempt to
preserve the wrapping from the source document (that is,
where there are nonsemantic newlines in the source, there
will be nonsemantic newlines in the output as well).
Automatic wrapping does not currently work in HTML output.
In `ipynb` output, this option affects wrapping of the
contents of markdown cells.
`--columns=`*NUMBER*
: Specify length of lines in characters. This affects text wrapping
in the generated source code (see `--wrap`). It also affects
calculation of column widths for plain text tables (see [Tables] below).
`--toc`, `--table-of-contents`
: 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. This option has no effect
unless `-s/--standalone` is used, and it has no effect
on `man`, `docbook4`, `docbook5`, or `jats` output.
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=`*NUMBER*
: Specify the number of section levels to include in the table
of contents. The default is 3 (which means that level-1, 2, and 3
headings will be listed in the contents).
`--strip-comments`
: Strip out HTML comments in the Markdown or Textile source,
rather than passing them on to Markdown, Textile or HTML
output as raw HTML. This does not apply to HTML comments
inside raw HTML blocks when the `markdown_in_html_blocks`
extension is not set.
`--no-highlight`
: Disables syntax highlighting for code blocks and inlines, even when
a language attribute is given.
`--highlight-style=`*STYLE*|*FILE*
: Specifies the coloring style to be used in highlighted source code.
Options are `pygments` (the default), `kate`, `monochrome`,
`breezeDark`, `espresso`, `zenburn`, `haddock`, and `tango`.
For more information on syntax highlighting in pandoc, see
[Syntax highlighting], below. See also
`--list-highlight-styles`.
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.
To generate the JSON version of an existing style,
use `--print-highlight-style`.
`--print-highlight-style=`*STYLE*|*FILE*
: Prints a JSON version of a highlighting style, which can
be modified, saved with a `.theme` extension, and used
with `--highlight-style`. This option may be used with
`-o`/`--output` to redirect output to a file, but
`-o`/`--output` must come before `--print-highlight-style`
on the command line.
`--syntax-definition=`*FILE*
: Instructs pandoc to load a KDE XML syntax definition file,
which will be used for syntax highlighting of appropriately
marked code blocks. This can be used to add support for
new languages or to use altered syntax definitions for
existing languages. This option may be repeated to add
multiple syntax definitions.
`-H` *FILE*, `--include-in-header=`*FILE*|*URL*
: Include contents of *FILE*, verbatim, at the end of the header.
This can be used, for example, to include special
CSS or JavaScript in HTML documents. This option can be used
repeatedly to include multiple files in the header. They will be
included in the order specified. Implies `--standalone`.
`-B` *FILE*, `--include-before-body=`*FILE*|*URL*
: Include contents of *FILE*, verbatim, at the beginning of the
document body (e.g. after the `<body>` tag in HTML, or the
`\begin{document}` command in LaTeX). This can be used to include
navigation bars or banners in HTML documents. This option can be
used repeatedly to include multiple files. They will be included in
the order specified. Implies `--standalone`.
`-A` *FILE*, `--include-after-body=`*FILE*|*URL*
: Include contents of *FILE*, verbatim, at the end of the document
body (before the `</body>` tag in HTML, or the
`\end{document}` command in LaTeX). This option can be used
repeatedly to include multiple files. They will be included in the
order specified. Implies `--standalone`.
`--resource-path=`*SEARCHPATH*
: List of paths to search for images and other resources.
The paths should be separated by `:` on Linux, UNIX, and
macOS systems, and by `;` on Windows. If `--resource-path`
is not specified, the default resource path is the working
directory. Note that, if `--resource-path` is specified,
the working directory must be explicitly listed or it
will not be searched. For example:
`--resource-path=.:test` will search the working directory
and the `test` subdirectory, in that order.
`--resource-path` only has an effect if (a) the output
format embeds images (for example, `docx`, `pdf`, or `html`
with `--self-contained`) or (b) it is used together with
`--extract-media`.
`--request-header=`*NAME*`:`*VAL*
: Set the request header *NAME* to the value *VAL* when making
HTTP requests (for example, when a URL is given on the
command line, or when resources used in a document must be
downloaded). If you're behind a proxy, you also need to set
the environment variable `http_proxy` to `http://...`.
`--no-check-certificate`
: Disable the certificate verification to allow access to
unsecure HTTP resources (for example when the certificate
is no longer valid or self signed).
## Options affecting specific writers {.options}
`--self-contained`
: Produce a standalone HTML file with no external dependencies, using
`data:` URIs to incorporate the contents of linked scripts, stylesheets,
images, and videos. Implies `--standalone`. The resulting file should be
"self-contained," in the sense that it needs no external files and no net
access to be displayed properly by a browser. This option works only with
HTML output formats, including `html4`, `html5`, `html+lhs`, `html5+lhs`,
`s5`, `slidy`, `slideous`, `dzslides`, and `revealjs`. Scripts, images,
and stylesheets at absolute URLs will be downloaded; those at relative
URLs will be sought relative to the working directory (if the first source
file is local) or relative to the base URL (if the first source
file is remote). Elements with the attribute
`data-external="1"` will be left alone; the documents they
link to will not be incorporated in the document.
Limitation: resources that are loaded dynamically through
JavaScript cannot be incorporated; as a result,
`--self-contained` does not work with `--mathjax`, and some
advanced features (e.g. zoom or speaker notes) may not work
in an offline "self-contained" `reveal.js` slide show.
`--html-q-tags`
: Use `<q>` tags for quotes in HTML. (This option only has an
effect if the `smart` extension is enabled for the input
format used.)
`--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.
`--reference-links`
: Use reference-style links, rather than inline links, in writing Markdown
or reStructuredText. By default inline links are used. The
placement of link references is affected by the
`--reference-location` option.
`--reference-location=block`|`section`|`document`
: Specify whether footnotes (and references, if `reference-links` is
set) are placed at the end of the current (top-level) block, the
current section, or the document. The default is
`document`. Currently only affects the markdown writer.
`--markdown-headings=setext`|`atx`
: Specify whether to use ATX-style (`#`-prefixed) or
Setext-style (underlined) headings for level 1 and 2
headings in Markdown output. (The default is `atx`.)
ATX-style headings are always used for levels 3+.
This option also affects Markdown cells in `ipynb` output.
`--atx-headers`
: *Deprecated synonym for `--markdown-headings=atx`.*
`--top-level-division=default`|`section`|`chapter`|`part`
: Treat top-level headings as the given division type in
LaTeX, ConTeXt, DocBook, and TEI output. The hierarchy
order is part, chapter, then section; all headings are
shifted such that the top-level heading becomes the
specified type. The default behavior is to determine the
best division type via heuristics: unless other conditions
apply, `section` is chosen. When the `documentclass`
variable is set to `report`, `book`, or `memoir` (unless the
`article` option is specified), `chapter` is implied as the
setting for this option. If `beamer` is the output format,
specifying either `chapter` or `part` will cause top-level
headings to become `\part{..}`, while second-level headings
remain as their default type.
