Description
[description]
Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read markdown and (subsets of) Textile, reStructuredText, HTML, LaTeX, MediaWiki markup, Haddock markup, OPML, Emacs Org-mode and DocBook; and it can write plain text, markdown, reStructuredText, XHTML, HTML 5, LaTeX (including beamer slide shows), ConTeXt, RTF, OPML, DocBook, OpenDocument, ODT, Word docx, GNU Texinfo, MediaWiki markup, EPUB (v2 or v3), FictionBook2, Textile, groff man pages, Emacs Org-Mode, AsciiDoc, InDesign ICML, and Slidy, Slideous, DZSlides, reveal.js or S5 HTML slide shows. It can also produce PDF output on systems where LaTeX is installed.
Pandoc’s enhanced version of markdown includes syntax for footnotes,
tables, flexible ordered lists, definition lists, fenced code blocks,
superscript, subscript, strikeout, title blocks, automatic tables of
contents, embedded LaTeX math, citations, and markdown inside HTML block
elements. (These enhancements, described below under
[pandocs-markdown]Pandoc’s markdown, can be disabled using the
markdown_strict
input or output format.)
In contrast to most existing tools for converting markdown to HTML, which use regex substitutions, 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, 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.
Using pandoc
[using-pandoc]
If no input-file is specified, input is read from stdin. Otherwise,
the input-files are concatenated (with a blank line between each) and
used as input. Output goes to stdout by default (though output to
stdout is disabled for the odt
, docx
, epub
, and epub3
output
formats). For output to a file, use the -o
option:
pandoc -o output.html input.txt
Instead of a file, an absolute URI may be given. In this case pandoc will fetch the content using HTTP:
pandoc -f html -t markdown http://www.fsf.org
If multiple input files are given, pandoc
will concatenate them all
(with blank lines between them) before parsing.
The format of the input and output can be specified explicitly using
command-line options. The input format can be specified using the
-r/--read
or -f/--from
options, the output format using the
-w/--write
or -t/--to
options. 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 output formats are listed below under the -t/--to
option.
Supported input formats are listed below under the -f/--from
option.
Note that the rst
, textile
, latex
, and html
readers are not
complete; there are some constructs that they do not parse.
If the input or output format is not specified explicitly, pandoc
will
attempt to guess it from the extensions of the input and output
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 unless explicitly specified.
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
Creating a PDF
[creating-a-pdf]
Earlier versions of pandoc came with a program, markdown2pdf
, that
used pandoc and pdflatex to produce a PDF. This is no longer needed,
since pandoc
can now produce pdf
output itself. To produce a PDF,
simply specify an output file with a .pdf
extension. Pandoc will
create a latex file and use pdflatex (or another engine, see
--latex-engine
) to convert it to PDF:
pandoc test.txt -o test.pdf
Production of a PDF requires that a LaTeX engine be installed (see
--latex-engine
, below), and assumes that the following LaTeX packages
are available: amssymb
, amsmath
, ifxetex
, ifluatex
, listings
(if the --listings
option is used), fancyvrb
, longtable
,
booktabs
, url
, graphicx
, hyperref
, ulem
, babel
(if the
lang
variable is set), fontspec
(if xelatex
or lualatex
is used
as the LaTeX engine), xltxtra
and xunicode
(if xelatex
is used).
hsmarkdown
[hsmarkdown]
A user who wants a drop-in replacement for Markdown.pl
may create a
symbolic link to the pandoc
executable called hsmarkdown
. When
invoked under the name hsmarkdown
, pandoc
will behave as if invoked
with -f markdown_strict --email-obfuscation=references
, and all
command-line options will be treated as regular arguments. However, this
approach does not work under Cygwin, due to problems with its simulation
of symbolic links.

FORMAT
~ Specify input format. FORMAT can be native
(native Haskell),
json
(JSON version of native AST), markdown
(pandoc’s extended
markdown), markdown_strict
(original unextended markdown),
markdown_phpextra
(PHP Markdown Extra extended markdown),
markdown_github

(MediaWiki markup),
haddock
(Haddock markup), or latex
(LaTeX). If +lhs
is
appended to markdown
, rst
, latex
, or html
, the input will be
treated as literate Haskell source: see
[literate-haskell-support]Literate Haskell support, below. Markdown
syntax extensions can be individually enabled or disabled by
appending +EXTENSION
or -EXTENSION
to the format name. So, for
example, markdown_strict+footnotes+definition_lists
is strict
markdown with footnotes and definition lists enabled, and
markdown-pipe_tables+hard_line_breaks
is pandoc’s markdown without
pipe tables and with hard line breaks. See
[pandocs-markdown]Pandoc’s markdown, below, for a list of extensions
and their names.

[custom-writers]Custom writers, below). Note that odt
, epub
, and
epub3
output will not be directed to stdout; an output filename
must be specified using the -o/--output
option. If +lhs
is
appended to markdown
, rst
, latex
, beamer
, html
, or
html5
, the output will be rendered as literate Haskell source: see
[literate-haskell-support]Literate Haskell support, below. Markdown
syntax extensions can be individually enabled or disabled by
appending +EXTENSION
or -EXTENSION
to the format name, as
described above under -f
.
-o
FILE, --output=
FILE
~ Write output to FILE instead of stdout. If FILE is -
, output
will go to stdout. (Exception: if the output format is odt
,
docx
, epub
, or epub3
, output to stdout is disabled.)
--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. This is
$HOME/.pandoc
in unix,
C:\Documents And Settings\USERNAME\Application Data\pandoc
in Windows XP, and
C:\Users\USERNAME\AppData\Roaming\pandoc
in Windows 7. (You can find the default user data directory on your
system by looking at the output of `pandoc --version`.) A
`reference.odt`, `reference.docx`, `default.csl`, `epub.css`,
`templates`, `slidy`, `slideous`, or `s5` directory placed in this
directory will override pandoc’s normal defaults.
-v
, --version
~ Print version.
-h
, --help
~ Show usage message.
Reader options
[reader-options]
-R
, --parse-raw
~ Parse untranslatable HTML codes and LaTeX environments as raw HTML
or LaTeX, instead of ignoring them. Affects only HTML and LaTeX
input. Raw HTML can be printed in markdown, reStructuredText, HTML,
Slidy, Slideous, DZSlides, reveal.js, and S5 output; raw LaTeX can
be printed in markdown, reStructuredText, LaTeX, and ConTeXt output.
The default is for the readers to omit untranslatable HTML codes and
LaTeX environments. (The LaTeX reader does pass through
untranslatable LaTeX commands, even if -R
is not specified.)
-S
, --smart
~ Produce typographically correct output, converting straight quotes
to curly quotes, ---
to em-dashes, --
to en-dashes, and ...
to
ellipses. Nonbreaking spaces are inserted after certain
abbreviations, such as “Mr.” (Note: This option is significant only
when the input format is markdown
, markdown_strict
, or
textile
. It is selected automatically when the input format is
textile
or the output format is latex
or context
, unless
--no-tex-ligatures
is used.)
--old-dashes
~ Selects the pandoc <= 1.8.2.1 behavior for parsing smart dashes: -
before a numeral is an en-dash, and --
is an em-dash. This option
is selected automatically for textile
input.
--base-header-level=
NUMBER
~ Specify the base level for headers (defaults to 1).
--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.
--filter=
EXECUTABLE
~ 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. See
<http://github.com/jgm/pandocfilters> for the module and several
examples. Note that the *EXECUTABLE* will be sought in the user’s
`PATH`, and not in the working directory, if no directory is
provided. If you want to run a script in the working directory,
preface the filename with `./`.
-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.
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).
--normalize
~ Normalize the document after reading: merge adjacent Str
or Emph
elements, for example, and remove repeated Space
s.
-p
, --preserve-tabs
~ Preserve tabs instead of converting them to spaces (the default).
Note that this will only affect tabs in literal code spans and code
blocks; tabs in regular text will be treated as spaces.
--tab-stop=
NUMBER
~ Specify the number of spaces per tab (default is 4).
General writer options
[general-writer-options]
-s
, --standalone
~ Produce output with an appropriate header and footer (e.g. a
standalone HTML, LaTeX, or RTF file, not a fragment). This option is
set automatically for pdf
, epub
, epub3
, fb2
, docx
, and
odt
output.
--template=
FILE
~ Use FILE as a custom template for the generated document. Implies
--standalone
. See [templates]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 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. This is generally only useful when
the --template
option is used to specify a custom template, since
pandoc automatically sets the variables used in the default
templates. If no VAL is specified, the key will be given the value
true
.
-D
FORMAT, --print-default-template=
FORMAT
~ Print the default template for an output FORMAT. (See -t
for a
list of possible FORMATs.)
--print-default-data-file=
FILE
~ Print a default data file.
--no-wrap
~ Disable text wrapping in output. By default, text is wrapped
appropriately for the output format.
--columns
=NUMBER
~ Specify length of lines in characters (for text wrapping).
--toc
, --table-of-contents
~ Include an automatically generated table of contents (or, in the
case of latex
, context
, and rst
, an instruction to create one)
in the output document. This option has no effect on man
,
docbook
, slidy
, slideous
, s5
, docx
, or odt
output.
--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
headers will be listed in the contents).
--no-highlight
~ Disables syntax highlighting for code blocks and inlines, even when
a language attribute is given.
--highlight-style
=STYLE
~ Specifies the coloring style to be used in highlighted source code.
Options are pygments
(the default), kate
, monochrome
,
espresso
, zenburn
, haddock
, and tango
.
-H
FILE, --include-in-header=
FILE
~ 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
~ 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
~ 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 be used repeatedly to include
multiple files. They will be included in the order specified.
Implies --standalone
.
Options affecting specific writers
[options-affecting-specific-writers]
--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. 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 html
, 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 first relative
to the working directory, then relative to the user data directory
(see --data-dir
), and finally relative to pandoc’s default data
directory. --self-contained
does not work with --mathjax
.
--offline
~ Deprecated synonym for --self-contained
.
-5
, --html5
~ Produce HTML5 instead of HTML4. This option has no effect for
writers other than html
. (Deprecated: Use the html5
output
format instead.)
--html-q-tags
~ Use <q>
tags for quotes in HTML.
--ascii
~ Use only ascii characters in output. Currently supported only for
HTML output (which uses numerical entities instead of UTF-8 when
this option is selected).
--reference-links
~ Use reference-style links, rather than inline links, in writing
markdown or reStructuredText. By default inline links are used.
--atx-headers
~ Use ATX style headers in markdown and asciidoc output. The default
is to use setext-style headers for levels 1-2, and then ATX headers.
--chapters
~ Treat top-level headers as chapters in LaTeX, ConTeXt, and DocBook
output. When the LaTeX template uses the report, book, or memoir
class, this option is implied. If beamer
is the output format,
top-level headers will become \part{..}
.
-N
, --number-sections
~ Number section headings in LaTeX, ConTeXt, HTML, or EPUB output. By
default, sections are not numbered. Sections with class unnumbered
will never be numbered, even if --number-sections
is specified.
--number-offset
=NUMBER[,NUMBER,…],
~ Offset for section headings in HTML output (ignored in other output
formats). The first number is added to the section number for
top-level headers, the second for second-level headers, and so on.
So, for example, if you want the first top-level header in your
document to be numbered “6”, specify --number-offset=5
. If your
document starts with a level-2 header which you want to be numbered
“1.5”, specify --number-offset=1,4
. Offsets are 0 by default.
Implies --number-sections
.
--no-tex-ligatures
~ Do not convert quotation marks, apostrophes, and dashes to the TeX
ligatures when writing LaTeX or ConTeXt. Instead, just use literal
unicode characters. This is needed for using advanced OpenType
features with XeLaTeX and LuaLaTeX. Note: normally --smart
is
selected automatically for LaTeX and ConTeXt output, but it must be
specified explicitly if --no-tex-ligatures
is selected. If you use
literal curly quotes, dashes, and ellipses in your source, then you
may want to use --no-tex-ligatures
without --smart
.
--listings
~ Use listings package for LaTeX code blocks
-i
, --incremental
~ Make list items in slide shows display incrementally (one by one).
The default is for lists to be displayed all at once.
--slide-level
=NUMBER
~ Specifies that headers with the specified level create slides (for
beamer
, s5
, slidy
, slideous
, dzslides
). Headers above this
level in the hierarchy are used to divide the slide show into
sections; headers below this level create subheads within a slide.
The default is to set the slide level based on the contents of the
document; see [structuring-the-slide-show]Structuring the slide
show, below.
--section-divs
~ Wrap sections in <div>
tags (or <section>
tags in HTML5), and
attach identifiers to the enclosing <div>
(or <section>
) rather
than the header itself. See
[header-identifiers-in-html-latex-and-context]Section identifiers,
below.
--email-obfuscation=
nonejavascriptreferences
~ Specify a method for obfuscating mailto:
links in HTML documents.
none leaves mailto:
links as they are. javascript obfuscates
them using javascript. references obfuscates them by printing
their letters as decimal or hexadecimal character references.
--id-prefix
=STRING
~ Specify a prefix to be added to all automatically generated
identifiers in HTML and DocBook output, and to footnote numbers in
markdown output. This is useful for preventing duplicate identifiers
when generating fragments to be included in other pages.
-T
STRING, --title-prefix=
STRING
~ Specify STRING as a prefix at the beginning of the title that
appears in the HTML header (but not in the title as it appears at
the beginning of the HTML body). Implies --standalone
.
-c
URL, --css=
URL
~ Link to a CSS style sheet. This option can be be used repeatedly to
include multiple files. They will be included in the order
specified.
--reference-odt=
FILE
~ Use the specified file as a style reference in producing an ODT. For
best results, the reference ODT should be a modified version of an
ODT produced using pandoc. The contents of the reference ODT are
ignored, but its stylesheets are used in the new ODT. If no
reference ODT is specified on the command line, pandoc will look for
a file reference.odt
in the user data directory (see
--data-dir
). If this is not found either, sensible defaults will
be used.
--reference-docx=
FILE
~ Use the specified file as a style reference in producing a docx
file. For best results, the reference docx should be a modified
version of a docx file produced using pandoc. The contents of the
reference docx are ignored, but its stylesheets are used in the new
docx. If no reference docx is specified on the command line, pandoc
will look for a file reference.docx
in the user data directory
(see --data-dir
). If this is not found either, sensible defaults
will be used. The following styles are used by pandoc: [paragraph]
Normal, Compact, Title, Authors, Date, Heading 1, Heading 2, Heading
3, Heading 4, Heading 5, Block Quote, Definition Term, Definition,
Body Text, Table Caption, Image Caption; [character] Default
Paragraph Font, Body Text Char, Verbatim Char, Footnote Ref, Link.
--epub-stylesheet=
FILE
~ Use the specified CSS file to style the EPUB. If no stylesheet is
specified, pandoc will look for a file epub.css
in the user data
directory (see --data-dir
). If it is not found there, sensible
defaults will be used.
--epub-cover-image=
FILE
~ Use the specified image as the EPUB cover. It is recommended that
the image be less than 1000px in width and height. Note that in a
markdown source document you can also specify cover-image
in a
YAML metadata block (see [epub-metadata]EPUB Metadata, below).
--epub-metadata=
FILE
~ Look in the specified XML file for metadata for the EPUB. The file
should contain a series of Dublin Core elements, as documented at
http://dublincore.org/documents/dces/. 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](http://www.w3.org/TR/NOTE-datetime)),
`<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. See below under
[epub-metadata]EPUB Metadata.
--epub-embed-font=
FILE
~ Embed the specified font in the EPUB. This option can be repeated to
embed multiple fonts. To use embedded fonts, you will need to add
declarations like the following to your CSS (see
--epub-stylesheet
):
@font-face {
font-family: DejaVuSans;
font-style: normal;
font-weight: normal;
src:url("DejaVuSans-Regular.ttf");
}
@font-face {
font-family: DejaVuSans;
font-style: normal;
font-weight: bold;
src:url("DejaVuSans-Bold.ttf");
}
@font-face {
font-family: DejaVuSans;
font-style: italic;
font-weight: normal;
src:url("DejaVuSans-Oblique.ttf");
}
@font-face {
font-family: DejaVuSans;
font-style: italic;
font-weight: bold;
src:url("DejaVuSans-BoldOblique.ttf");
}
body { font-family: "DejaVuSans"; }
--epub-chapter-level=
NUMBER
~ Specify the header level at which to split the EPUB into separate
“chapter” files. The default is to split into chapters at level 1
headers. 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 headers, one might want to use a chapter
level of 2 or 3.
--latex-engine=
pdflatexlualatexxelatex
~ Use the specified LaTeX engine when producing PDF output. The
default is pdflatex
. If the engine is not in your PATH, the full
path of the engine may be specified here.
Citation rendering
[citation-rendering]
--bibliography=
FILE
~ Set the bibliography
field in the document’s metadata to FILE,
overriding any value set in the metadata, and process citations
using pandoc-citeproc
. (This is equivalent to
--metadata bibliography=FILE --filter pandoc-citeproc
.)
--csl=
FILE
~ Set the csl
field in the document’s metadata to FILE, overriding
any value set in the metadata. (This is equivalent to
--metadata csl=FILE
.)
--citation-abbreviations=
FILE
~ Set the citation-abbreviations
field in the document’s metadata to
FILE, overriding any value set in the metadata. (This is
equivalent to --metadata citation-abbreviations=FILE
.)
--natbib
~ Use natbib for citations in LaTeX output. This option is not for use
with the pandoc-citeproc
filter or with PDF output. It is intended
for use in producing a LaTeX file that can be processed with
pdflatex and bibtex.
--biblatex
~ Use biblatex for citations in LaTeX output. This option is not for
use with the pandoc-citeproc
filter or with PDF output. It is
intended for use in producing a LaTeX file that can be processed
with pdflatex and bibtex or biber.
Math rendering in HTML
[math-rendering-in-html]
-m
[URL], --latexmathml
[=URL]
~ Use the LaTeXMathML script to
display embedded TeX math in HTML output. To insert a link to a
local copy of the LaTeXMathML.js
script, provide a URL. If no
URL is provided, the contents of the script will be inserted
directly into the HTML header, preserving portability at the price
of efficiency. If you plan to use math on several pages, it is much
better to link to a copy of the script, so it can be cached.
--mathml
[=URL]
~ Convert TeX math to MathML (in docbook
as well as html
and
html5
). In standalone html
output, a small javascript (or a link
to such a script if a URL is supplied) will be inserted that
allows the MathML to be viewed on some browsers.
--jsmath
[=URL]
~ Use jsMath to display
embedded TeX math in HTML output. The URL should point to the
jsMath load script (e.g. jsMath/easy/load.js
); if provided, it
will be linked to in the header of standalone HTML documents. If a
URL is not provided, no link to the jsMath load script will be
inserted; it is then up to the author to provide such a link in the
HTML template.
--mathjax
[=URL]
~ Use MathJax to display embedded TeX math
in HTML output. The URL should point to the MathJax.js
load
script. If a URL is not provided, a link to the MathJax CDN will
be inserted.
--gladtex
~ Enclose TeX math in <eq>
tags in HTML output. These can then be
processed by gladTeX to
produce links to images of the typeset formulas.
--mimetex
[=URL]
~ Render TeX math using the
mimeTeX CGI script. If URL
is not specified, it is assumed that the script is at
/cgi-bin/mimetex.cgi
.
--webtex
[=URL]
~ Render TeX formulas using an external script that converts TeX
formulas to images. The formula will be concatenated with the URL
provided. If URL is not specified, the Google Chart API will be
used.
Options for wrapper scripts
[options-for-wrapper-scripts]
--dump-args
~ Print information about command-line arguments to stdout, then
exit. This option is intended primarily for use in wrapper scripts.
The first line of output contains the name of the output file
specified with the -o
option, or -
(for stdout) if no output
file was specified. The remaining lines contain the command-line
arguments, one per line, in the order they appear. These do not
include regular Pandoc options and their arguments, but do include
any options appearing after a --
separator at the end of the line.
--ignore-args
~ Ignore command-line arguments (for use in wrapper scripts). Regular
Pandoc options are not ignored. Thus, for example,
pandoc --ignore-args -o foo.html -s foo.txt -- -e latin1
is equivalent to
pandoc -o foo.html -s
When the -s/--standalone
option is used, pandoc uses a template to add
header and footer material that is needed for a self-standing document.
To see the default template that is used, just type
pandoc -D FORMAT
where FORMAT
is the name of the output format. A custom template can
be specified using the --template
option. You can also override the
system default templates for a given output format FORMAT
by putting a
file templates/default.FORMAT
in the user data directory (see
--data-dir
, above). Exceptions: For odt
output, customize the
default.opendocument
template. For pdf
output, customize the
default.latex
template.
Templates may contain variables. Variable names are sequences of
alphanumerics, -
, and _
, starting with a letter. A variable name
surrounded by $
signs will be replaced by its value. For example, the
string $title$
in
<title>$title$</title>
will be replaced by the document title.
To write a literal $
in a template, use $$
.
Some variables are set automatically by pandoc. These vary somewhat
depending on the output format, but include metadata fields (such as
title
, author
, and date
) as well as the following:
header-includes
~ contents specified by -H/--include-in-header
(may have multiple
values)
toc
~ non-null value if --toc/--table-of-contents
was specified
include-before
~ contents specified by -B/--include-before-body
(may have multiple

Variables may be set at the command line using the -V/--variable
option. Variables set in this way override metadata fields with the same
name.
Templates may contain conditionals. The syntax is as follows:
$if(variable)$
X
$else$
Y
$endif$
This will include X
in the template if variable
has a non-null
value; otherwise it will include Y
. X
and Y
are placeholders for
any valid template text, and may include interpolated variables or other
conditionals. The $else$
section may be omitted.
When variables can have multiple values (for example, author
in a
multi-author document), you can use the $for$
keyword:
$for(author)$
<meta name="author" content="$author$" />
$endfor$
You can optionally specify a separator to be used between consecutive items:
$for(author)$$author$$sep$, $endfor$
A dot can be used to select a field of a variable that takes an object as its value. So, for example:
$author.name$ ($author.affiliation$)
If you use custom templates, you may need to revise them as pandoc changes. We recommend tracking the changes in the default templates, and modifying your custom templates accordingly. An easy way to do this is to fork the pandoc-templates repository (http://github.com/jgm/pandoc-templates) and merge in changes after each pandoc release.
Pandoc understands an extended and slightly revised version of John
Gruber’s markdown
syntax. This document explains the syntax, noting differences from
standard markdown. Except where noted, these differences can be
suppressed by using the markdown_strict
format instead of markdown
.
An extensions can be enabled by adding +EXTENSION
to the format name
and disabled by adding -EXTENSION
. For example,
markdown_strict+footnotes
is strict markdown with footnotes enabled,
while markdown-footnotes-pipe_tables
is pandoc’s markdown without
footnotes or pipe tables.
Philosophy
[philosophy]
Markdown is designed to be easy to write, and, even more importantly, easy to read:
A Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions. – John Gruber
This principle has guided pandoc’s decisions in finding syntax for tables, footnotes, and other extensions.
There is, however, one respect in which pandoc’s aims are different from the original aims of markdown. Whereas markdown was originally designed with HTML generation in mind, pandoc is designed for multiple output formats. Thus, while pandoc allows the embedding of raw HTML, it discourages it, and provides other, non-HTMLish ways of representing important document elements like definition lists, tables, mathematics, and footnotes.
Paragraphs
[paragraphs]
A paragraph is one or more lines of text followed by one or more blank line. Newlines are treated as spaces, so you can reflow your paragraphs as you like. If you need a hard line break, put two or more spaces at the end of a line.
Extension: escaped_line_breaks
A backslash followed by a newline is also a hard line break. Note: in multiline and grid table cells, this is the only way to create a hard line break, since trailing spaces in the cells are ignored.
Headers
[headers]
There are two kinds of headers, Setext and atx.
Setext-style headers
[setext-style-headers]
A setext-style header is a line of text “underlined” with a row of =
signs (for a level one header) or -
signs (for a level two header):
A level-one header
==================
A level-two header
------------------
The header text can contain inline formatting, such as emphasis (see [inline-formatting]Inline formatting, below).
Atx-style headers
[atx-style-headers]
An Atx-style header consists of one to six #
signs and a line of text,
optionally followed by any number of #
signs. The number of #
signs
at the beginning of the line is the header level:
## A level-two header
### A level-three header ###
As with setext-style headers, the header text can contain formatting:
# A level-one header with a [link](/url) and *emphasis*
Extension: blank_before_header
Standard markdown syntax does not require a blank line before a header.
Pandoc does require this (except, of course, at the beginning of the
document). The reason for the requirement is that it is all too easy for
a #
to end up at the beginning of a line by accident (perhaps through
line wrapping). Consider, for example:
I like several of their flavors of ice cream:
#22, for example, and #5.
Extension: header_attributes
Headers can be assigned attributes using this syntax at the end of the line containing the header text:
{#identifier .class .class key=value key=value}
Although this syntax allows assignment of classes and key/value
attributes, only identifiers currently have any affect in the writers
(and only in some writers: HTML, LaTeX, ConTeXt, Textile, AsciiDoc).
Thus, for example, the following headers will all be assigned the
identifier foo
:
# My header {#foo}
## My header ## {#foo}
My other header {#foo}
---------------
(This syntax is compatible with PHP Markdown Extra.)
Headers with the class unnumbered
will not be numbered, even if
--number-sections
is specified. A single hyphen (-
) in an attribute
context is equivalent to .unnumbered
, and preferable in non-English
documents. So,
# My header {-}
is just the same as
# My header {.unnumbered}
Extension: auto_identifiers
A header without an explicitly specified identifier will be automatically assigned a unique identifier based on the header text. To derive the identifier from the header text,
-
Remove all formatting, links, etc.
-
Remove all footnotes.
-
Remove all punctuation, except underscores, hyphens, and periods.
-
Replace all spaces and newlines with hyphens.
-
Convert all alphabetic characters to lowercase.
-
Remove everything up to the first letter (identifiers may not begin with a number or punctuation mark).
-
If nothing is left after this, use the identifier
section
.
Thus, for example,
[c]@ll@ Header & Identifier\
Header identifiers in HTML & header-identifiers-in-html
\
Dogs?–in my house? & dogs--in-my-house
\
HTML,
S5, or
RTF? &
html-s5-or-rtf
\
3. Applications & applications
\
33 & section
\
These rules should, in most cases, allow one to determine the identifier
from the header text. The exception is when several headers have the
same text; in this case, the first will get an identifier as described
above; the second will get the same identifier with -1
appended; the
third with -2
; and so on.
These identifiers are used to provide link targets in the table of
contents generated by the --toc--table-of-contents
option. They also
make it easy to provide links from one section of a document to another.
A link to this section, for example, might look like this:
See the section on
[header identifiers](#header-identifiers-in-html-latex-and-context).
Note, however, that this method of providing links to sections works only in HTML, LaTeX, and ConTeXt formats.
If the --section-divs
option is specified, then each section will be
wrapped in a div
(or a section
, if --html5
was specified), and the
identifier will be attached to the enclosing <div>
(or <section>
)
tag rather than the header itself. This allows entire sections to be
manipulated using javascript or treated differently in CSS.
Extension: implicit_header_references
Pandoc behaves as if reference links have been defined for each header. So, instead of
[header identifiers](#header-identifiers-in-html)
you can simply write
[header identifiers]
or
[header identifiers][]
or
[the section on header identifiers][header identifiers]
If there are multiple headers with identical text, the corresponding reference will link to the first one only, and you will need to use explicit links to link to the others, as described above.
Unlike regular reference links, these references are case-sensitive.
Note: if you have defined an explicit identifier for a header, then implicit references to it will not work.
Block quotations
[block-quotations]
Markdown uses email conventions for quoting blocks of text. A block
quotation is one or more paragraphs or other block elements (such as
lists or headers), with each line preceded by a >
character and a
space. (The >
need not start at the left margin, but it should not be
indented more than three spaces.)
> This is a block quote. This
> paragraph has two lines.
>
> 1. This is a list inside a block quote.
> 2. Second item.
A “lazy” form, which requires the >
character only on the first line
of each block, is also allowed:
> This is a block quote. This
paragraph has two lines.
> 1. This is a list inside a block quote.
2. Second item.
Among the block elements that can be contained in a block quote are other block quotes. That is, block quotes can be nested:
> This is a block quote.
>
> > A block quote within a block quote.
Extension: blank_before_blockquote
Standard markdown syntax does not require a blank line before a block
quote. Pandoc does require this (except, of course, at the beginning of
the document). The reason for the requirement is that it is all too easy
for a >
to end up at the beginning of a line by accident (perhaps
through line wrapping). So, unless the markdown_strict
format is used,
the following does not produce a nested block quote in pandoc:
> This is a block quote.
>> Nested.
Verbatim (code) blocks
[verbatim-code-blocks]
Indented code blocks
[indented-code-blocks]
A block of text indented four spaces (or one tab) is treated as verbatim text: that is, special characters do not trigger special formatting, and all spaces and line breaks are preserved. For example,
if (a > 3) {
moveShip(5 * gravity, DOWN);
}
The initial (four space or one tab) indentation is not considered part of the verbatim text, and is removed in the output.
Note: blank lines in the verbatim text need not begin with four spaces.
Extension: fenced_code_blocks
In addition to standard indented code blocks, Pandoc supports fenced
code blocks. These begin with a row of three or more tildes () or
backticks (
` ``) and end with a row of tildes or backticks that must
be at least as long as the starting row. Everything between these lines
is treated as code. No indentation is necessary:
~~~~~~~
if (a > 3) {
moveShip(5 * gravity, DOWN);
}
~~~~~~~
Like regular code blocks, fenced code blocks must be separated from surrounding text by blank lines.
If the code itself contains a row of tildes or backticks, just use a longer row of tildes or backticks at the start and end:
~~~~~~~~~~~~~~~~
~~~~~~~~~~
code including tildes
~~~~~~~~~~
~~~~~~~~~~~~~~~~
Optionally, you may attach attributes to the code block using this syntax:
~~~~ {#mycode .haskell .numberLines startFrom="100"}
qsort [] = []
qsort (x:xs) = qsort (filter (< x) xs) ++ [x] ++
qsort (filter (>= x) xs)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Here mycode
is an identifier, haskell
and numberLines
are classes,
and startFrom
is an attribute with value 100
. Some output formats
can use this information to do syntax highlighting. Currently, the only
output formats that uses this information are HTML and LaTeX. If
highlighting is supported for your output format and language, then the
code block above will appear highlighted, with numbered lines. (To see
which languages are supported, do pandoc --version
.) Otherwise, the
code block above will appear as follows:
<pre id="mycode" class="haskell numberLines" startFrom="100">
<code>
...
</code>
</pre>
A shortcut form can also be used for specifying the language of the code block:
```haskell
qsort [] = []
```
This is equivalent to:
``` {.haskell}
qsort [] = []
```
To prevent all highlighting, use the --no-highlight
flag. To set the
highlighting style, use --highlight-style
.
Line blocks
[line-blocks]
Extension: line_blocks
A line block is a sequence of lines beginning with a vertical bar (``) followed by a space. The division into lines will be preserved in the output, as will any leading spaces; otherwise, the lines will be formatted as markdown. This is useful for verse and addresses:
| The limerick packs laughs anatomical
| In space that is quite economical.
| But the good ones I've seen
| So seldom are clean
| And the clean ones so seldom are comical
| 200 Main St.
| Berkeley, CA 94718
The lines can be hard-wrapped if needed, but the continuation line must begin with a space.
| The Right Honorable Most Venerable and Righteous Samuel L.
Constable, Jr.
| 200 Main St.
| Berkeley, CA 94718
This syntax is borrowed from reStructuredText.
Lists
[lists]
Bullet lists
[bullet-lists]
A bullet list is a list of bulleted list items. A bulleted list item
begins with a bullet (*
, +
, or -
). Here is a simple example:
* one
* two
* three
This will produce a “compact” list. If you want a “loose” list, in which each item is formatted as a paragraph, put spaces between the items:
* one
* two
* three
The bullets need not be flush with the left margin; they may be indented one, two, or three spaces. The bullet must be followed by whitespace.
List items look best if subsequent lines are flush with the first line (after the bullet):
* here is my first
list item.
* and my second.
But markdown also allows a “lazy” format:
* here is my first
list item.
* and my second.
The four-space rule
[the-four-space-rule]
A list item may contain multiple paragraphs and other block-level content. However, subsequent paragraphs must be preceded by a blank line and indented four spaces or a tab. The list will look better if the first paragraph is aligned with the rest:
* First paragraph.
Continued.
* Second paragraph. With a code block, which must be indented
eight spaces:
{ code }
List items may include other lists. In this case the preceding blank line is optional. The nested list must be indented four spaces or one tab:
* fruits
+ apples
- macintosh
- red delicious
+ pears
+ peaches
* vegetables
+ broccoli
+ chard
As noted above, markdown allows you to write list items “lazily,” instead of indenting continuation lines. However, if there are multiple paragraphs or other blocks in a list item, the first line of each must be indented.
+ A lazy, lazy, list
item.
+ Another one; this looks
bad but is legal.
Second paragraph of second
list item.
Note: Although the four-space rule for continuation paragraphs comes
from the official markdown syntax
guide, the
reference implementation, Markdown.pl
, does not follow it. So pandoc
will give different results than Markdown.pl
when authors have
indented continuation paragraphs fewer than four spaces.
The markdown syntax guide is not explicit whether the four-space rule applies to all block-level content in a list item; it only mentions paragraphs and code blocks. But it implies that the rule applies to all block-level content (including nested lists), and pandoc interprets it that way.
Ordered lists
[ordered-lists]
Ordered lists work just like bulleted lists, except that the items begin with enumerators rather than bullets.
In standard markdown, enumerators are decimal numbers followed by a period and a space. The numbers themselves are ignored, so there is no difference between this list:
1. one
2. two
3. three
and this one:
5. one
7. two
1. three
Extension: fancy_lists
Unlike standard markdown, Pandoc allows ordered list items to be marked with uppercase and lowercase letters and roman numerals, in addition to arabic numerals. List markers may be enclosed in parentheses or followed by a single right-parentheses or period. They must be separated from the text that follows by at least one space, and, if the list marker is a capital letter with a period, by at least two spaces.1
The fancy_lists
extension also allows ‘#
’ to be used as an ordered
list marker in place of a numeral:
#. one
#. two
Extension: startnum
Pandoc also pays attention to the type of list marker used, and to the starting number, and both of these are preserved where possible in the output format. Thus, the following yields a list with numbers followed by a single parenthesis, starting with 9, and a sublist with lowercase roman numerals:
9) Ninth
10) Tenth
11) Eleventh
i. subone
ii. subtwo
iii. subthree
Pandoc will start a new list each time a different type of list marker is used. So, the following will create three lists:
(2) Two
(5) Three
1. Four
* Five
If default list markers are desired, use #.
:
#. one
#. two
#. three
Definition lists
[definition-lists]
Extension: definition_lists
Pandoc supports definition lists, using a syntax inspired by PHP Markdown Extra and reStructuredText:2
Term 1
: Definition 1
Term 2 with *inline markup*
: Definition 2
{ some code, part of Definition 2 }
Third paragraph of definition 2.
Each term must fit on one line, which may optionally be followed by a blank line, and must be followed by one or more definitions. A definition begins with a colon or tilde, which may be indented one or two spaces. The body of the definition (including the first line, aside from the colon or tilde) should be indented four spaces. A term may have multiple definitions, and each definition may consist of one or more block elements (paragraph, code block, list, etc.), each indented four spaces or one tab stop.
If you leave space after the definition (as in the example above), the blocks of the definitions will be considered paragraphs. In some output formats, this will mean greater spacing between term/definition pairs. For a compact definition list, do not leave space between the definition and the next term:
Term 1
~ Definition 1
Term 2
~ Definition 2a
~ Definition 2b
Numbered example lists
[numbered-example-lists]
Extension: example_lists
The special list marker @
can be used for sequentially numbered
examples. The first list item with a @
marker will be numbered ‘1’,
the next ‘2’, and so on, throughout the document. The numbered examples
need not occur in a single list; each new list using @
will take up
where the last stopped. So, for example:
(@) My first example will be numbered (1).
(@) My second example will be numbered (2).
Explanation of examples.
(@) My third example will be numbered (3).
Numbered examples can be labeled and referred to elsewhere in the document:
(@good) This is a good example.
As (@good) illustrates, ...
The label can be any string of alphanumeric characters, underscores, or hyphens.
Compact and loose lists
[compact-and-loose-lists]
Pandoc behaves differently from Markdown.pl
on some “edge cases”
involving lists. Consider this source:
+ First
+ Second:
- Fee
- Fie
- Foe
+ Third
Pandoc transforms this into a “compact list” (with no <p>
tags around
“First”, “Second”, or “Third”), while markdown puts <p>
tags around
“Second” and “Third” (but not “First”), because of the blank space
around “Third”. Pandoc follows a simple rule: if the text is followed by
a blank line, it is treated as a paragraph. Since “Second” is followed
by a list, and not a blank line, it isn’t treated as a paragraph. The
fact that the list is followed by a blank line is irrelevant. (Note:
Pandoc works this way even when the markdown_strict
format is
specified. This behavior is consistent with the official markdown syntax
description, even though it is different from that of Markdown.pl
.)
Ending a list
[ending-a-list]
What if you want to put an indented code block after a list?
- item one
- item two
{ my code block }
Trouble! Here pandoc (like other markdown implementations) will treat
{ my code block }
as the second paragraph of item two, and not as a
code block.
To “cut off” the list after item two, you can insert some non-indented content, like an HTML comment, which won’t produce visible output in any format:
- item one
- item two
<!-- end of list -->
{ my code block }
You can use the same trick if you want two consecutive lists instead of one big list:
1. one
2. two
3. three
<!-- -->
1. uno
2. dos
3. tres
Horizontal rules
[horizontal-rules]
A line containing a row of three or more *
, -
, or _
characters
(optionally separated by spaces) produces a horizontal rule:
* * * *
---------------
Tables
[tables]
Four kinds of tables may be used. The first three kinds presuppose the use of a fixed-width font, such as Courier. The fourth kind can be used with proportionally spaced fonts, as it does not require lining up columns.
Simple tables
[simple-tables]
Extension: simple_tables
, table_captions
Simple tables look like this:
Right Left Center Default
------- ------ ---------- -------
12 12 12 12
123 123 123 123
1 1 1 1
Table: Demonstration of simple table syntax.
The headers and table rows must each fit on one line. Column alignments are determined by the position of the header text relative to the dashed line below it:3
-
If the dashed line is flush with the header text on the right side but extends beyond it on the left, the column is right-aligned.
-
If the dashed line is flush with the header text on the left side but extends beyond it on the right, the column is left-aligned.
-
If the dashed line extends beyond the header text on both sides, the column is centered.
-
If the dashed line is flush with the header text on both sides, the default alignment is used (in most cases, this will be left).
The table must end with a blank line, or a line of dashes followed by a
blank line. A caption may optionally be provided (as illustrated in the
example above). A caption is a paragraph beginning with the string
Table:
(or just :
), which will be stripped off. It may appear either
before or after the table.
The column headers may be omitted, provided a dashed line is used to end the table. For example:
------- ------ ---------- -------
12 12 12 12
123 123 123 123
1 1 1 1
------- ------ ---------- -------
When headers are omitted, column alignments are determined on the basis of the first line of the table body. So, in the tables above, the columns would be right, left, center, and right aligned, respectively.
Multiline tables
[multiline-tables]
Extension: multiline_tables
, table_captions
Multiline tables allow headers and table rows to span multiple lines of text (but cells that span multiple columns or rows of the table are not supported). Here is an example:
-------------------------------------------------------------
Centered Default Right Left
Header Aligned Aligned Aligned
----------- ------- --------------- -------------------------
First row 12.0 Example of a row that
spans multiple lines.
Second row 5.0 Here's another one. Note
the blank line between
rows.
-------------------------------------------------------------
Table: Here's the caption. It, too, may span
multiple lines.
These work like simple tables, but with the following differences:
-
They must begin with a row of dashes, before the header text (unless the headers are omitted).
-
They must end with a row of dashes, then a blank line.
-
The rows must be separated by blank lines.
In multiline tables, the table parser pays attention to the widths of the columns, and the writers try to reproduce these relative widths in the output. So, if you find that one of the columns is too narrow in the output, try widening it in the markdown source.
Headers may be omitted in multiline tables as well as simple tables:
----------- ------- --------------- -------------------------
First row 12.0 Example of a row that
spans multiple lines.
Second row 5.0 Here's another one. Note
the blank line between
rows.
----------- ------- --------------- -------------------------
: Here's a multiline table without headers.
It is possible for a multiline table to have just one row, but the row should be followed by a blank line (and then the row of dashes that ends the table), or the table may be interpreted as a simple table.
Grid tables
[grid-tables]
Extension: grid_tables
, table_captions
Grid tables look like this:
: Sample grid table.
+---------------+---------------+--------------------+
| Fruit | Price | Advantages |
+===============+===============+====================+
| Bananas | $1.34 | - built-in wrapper |
| | | - bright color |
+---------------+---------------+--------------------+
| Oranges | $2.10 | - cures scurvy |
| | | - tasty |
+---------------+---------------+--------------------+
The row of =
s separates the header from the table body, and can be
omitted for a headerless table. The cells of grid tables may contain
arbitrary block elements (multiple paragraphs, code blocks, lists,
etc.). Alignments are not supported, nor are cells that span multiple
columns or rows. Grid tables can be created easily using Emacs table
mode.
Pipe tables
[pipe-tables]
Extension: pipe_tables
, table_captions
Pipe tables look like this:
| Right | Left | Default | Center |
|------:|:-----|---------|:------:|
| 12 | 12 | 12 | 12 |
| 123 | 123 | 123 | 123 |
| 1 | 1 | 1 | 1 |
: Demonstration of simple table syntax.
The syntax is the same as in PHP markdown extra. The beginning and ending pipe characters are optional, but pipes are required between all columns. The colons indicate column alignment as shown. The header can be omitted, but the horizontal line must still be included, as it defines column alignments.
Since the pipes indicate column boundaries, columns need not be vertically aligned, as they are in the above example. So, this is a perfectly legal (though ugly) pipe table:
fruit| price
-----|-----:
apple|2.05
pear|1.37
orange|3.09
The cells of pipe tables cannot contain block elements like paragraphs and lists, and cannot span multiple lines.
Note: Pandoc also recognizes pipe tables of the following form, as can produced by Emacs’ orgtbl-mode:
| One | Two |
|-----+-------|
| my | table |
| is | nice |
The difference is that +
is used instead of ``. Other orgtbl features
are not supported. In particular, to get non-default column alignment,
you’ll need to add colons as above.
Title block
[title-block]
Extension: pandoc_title_block
If the file begins with a title block
% title
% author(s) (separated by semicolons)
% date
it will be parsed as bibliographic information, not regular text. (It will be used, for example, in the title of standalone LaTeX or HTML output.) The block may contain just a title, a title and an author, or all three elements. If you want to include an author but no title, or a title and a date but no author, you need a blank line:
%
% Author
% My title
%
% June 15, 2006
The title may occupy multiple lines, but continuation lines must begin with leading space, thus:
% My title
on multiple lines
If a document has multiple authors, the authors may be put on separate lines with leading space, or separated by semicolons, or both. So, all of the following are equivalent:
% Author One
Author Two
% Author One; Author Two
% Author One;
Author Two
The date must fit on one line.
All three metadata fields may contain standard inline formatting (italics, links, footnotes, etc.).
Title blocks will always be parsed, but they will affect the output only
when the --standalone
(-s
) option is chosen. In HTML output, titles
will appear twice: once in the document head – this is the title that
will appear at the top of the window in a browser – and once at the
beginning of the document body. The title in the document head can have
an optional prefix attached (--title-prefix
or -T
option). The title
in the body appears as an H1 element with class “title”, so it can be
suppressed or reformatted with CSS. If a title prefix is specified with
-T
and no title block appears in the document, the title prefix will
be used by itself as the HTML title.
The man page writer extracts a title, man page section number, and other header and footer information from the title line. The title is assumed to be the first word on the title line, which may optionally end with a (single-digit) section number in parentheses. (There should be no space between the title and the parentheses.) Anything after this is assumed to be additional footer and header text. A single pipe character (``) should be used to separate the footer text from the header text. Thus,
% PANDOC(1)
will yield a man page with the title PANDOC
and section 1.
% PANDOC(1) Pandoc User Manuals
will also have “Pandoc User Manuals” in the footer.
% PANDOC(1) Pandoc User Manuals | Version 4.0
will also have “Version 4.0” in the header.
YAML metadata block
[yaml-metadata-block]
Extension: yaml_metadata_block
A YAML metadata block is a valid YAML object, delimited by a line of
three hyphens (---
) at the top and a line of three hyphens (---
) or
three dots (...
) at the bottom. A YAML metadata block may occur
anywhere in the document, but if it is not at the beginning, it must be
preceded by a blank line.
Metadata will be taken from the fields of the YAML object and added to any existing document metadata. Metadata can contain lists and objects (nested arbitrarily), but all string scalars will be interpreted as markdown. Fields with names ending in an underscore will be ignored by pandoc. (They may be given a role by external processors.)
A document may contain multiple metadata blocks. The metadata fields will be combined through a left-biased union: if two metadata blocks attempt to set the same field, the value from the first block will be taken.
Note that YAML escaping rules must be followed. Thus, for example, if a title contains a colon, it must be quoted. The pipe character (``) can be used to begin an indented block that will be interpreted literally, without need for escaping. This form is necessary when the field contains blank lines:
---
title: 'This is the title: it contains a colon'
author:
- name: Author One
affiliation: University of Somewhere
- name: Author Two
affiliation: University of Nowhere
tags: [nothing, nothingness]
abstract: |
This is the abstract.
It consists of two paragraphs.
...
Template variables will be set automatically from the metadata. Thus,
for example, in writing HTML, the variable abstract
will be set to the
HTML equivalent of the markdown in the abstract
field:
<p>This is the abstract.</p>
<p>It consists of two paragraphs.</p>
Note: The author
variable in the default templates expects a simple
list or string. To use the structured authors in the example, you would
need a custom template. For example:
$for(author)$
$if(author.name)$
$author.name$$if(author.affiliation)$ ($author.affiliation$)$endif$
$else$
$author$
$endif$
$endfor$
Backslash escapes
[backslash-escapes]
Extension: all_symbols_escapable
Except inside a code block or inline code, any punctuation or space character preceded by a backslash will be treated literally, even if it would normally indicate formatting. Thus, for example, if one writes
*\*hello\**
one will get
<em>*hello*</em>
instead of
<strong>hello</strong>
This rule is easier to remember than standard markdown’s rule, which allows only the following characters to be backslash-escaped:
\`*_{}[]()>#+-.!
(However, if the markdown_strict
format is used, the standard markdown
rule will be used.)
A backslash-escaped space is parsed as a nonbreaking space. It will
appear in TeX output as ` and in HTML and XML as
\ or
\ `.
A backslash-escaped newline (i.e. a backslash occurring at the end of a
line) is parsed as a hard line break. It will appear in TeX output as
\\
and in HTML as <br />
. This is a nice alternative to markdown’s
“invisible” way of indicating hard line breaks using two trailing spaces
on a line.
Backslash escapes do not work in verbatim contexts.
Smart punctuation
[smart-punctuation]
Extension
If the --smart
option is specified, pandoc will produce
typographically correct output, converting straight quotes to curly
quotes, ---
to em-dashes, --
to en-dashes, and ...
to ellipses.
Nonbreaking spaces are inserted after certain abbreviations, such as
“Mr.”
Note: if your LaTeX template uses the csquotes
package, pandoc will
detect automatically this and use \enquote{...}
for quoted text.
Emphasis
[emphasis]
To emphasize some text, surround it with *
s or _
, like this:
This text is _emphasized with underscores_, and this
is *emphasized with asterisks*.
Double *
or _
produces strong emphasis:
This is **strong emphasis** and __with underscores__.
A *
or _
character surrounded by spaces, or backslash-escaped, will
not trigger emphasis:
This is * not emphasized *, and \*neither is this\*.
Extension: intraword_underscores
Because _
is sometimes used inside words and identifiers, pandoc does
not interpret a _
surrounded by alphanumeric characters as an emphasis
marker. If you want to emphasize just part of a word, use *
:
feas*ible*, not feas*able*.
Strikeout
[strikeout]
Extension: strikeout
To strikeout a section of text with a horizontal line, begin and end it with ``. Thus, for example,
This ~~is deleted text.~~
Superscripts and subscripts
[superscripts-and-subscripts]
Extension: superscript
, subscript
Superscripts may be written by surrounding the superscripted text by ^
characters; subscripts may be written by surrounding the subscripted
text by `` characters. Thus, for example,
H~2~O is a liquid. 2^10^ is 1024.
If the superscripted or subscripted text contains spaces, these spaces
must be escaped with backslashes. (This is to prevent accidental
superscripting and subscripting through the ordinary use of ` and
^.)
Thus, if you want the letter P with ‘a cat’ in subscripts, use
Pa\ cat, not
Pa cat`.
Verbatim
[verbatim]
To make a short span of text verbatim, put it inside backticks:
What is the difference between `>>=` and `>>`?
If the verbatim text includes a backtick, use double backticks:
Here is a literal backtick `` ` ``.
(The spaces after the opening backticks and before the closing backticks will be ignored.)
The general rule is that a verbatim span starts with a string of consecutive backticks (optionally followed by a space) and ends with a string of the same number of backticks (optionally preceded by a space).
Note that backslash-escapes (and other markdown constructs) do not work in verbatim contexts:
This is a backslash followed by an asterisk: `\*`.
Extension: inline_code_attributes
Attributes can be attached to verbatim text, just as with [fenced-code-blocks]fenced code blocks:
`<$>`{.haskell}
Math
[math]
Extension: tex_math_dollars
Anything between two $
characters will be treated as TeX math. The
opening $
must have a character immediately to its right, while the
closing $
must have a character immediately to its left. Thus,
$20,000 and $30,000
won’t parse as math. If for some reason you need
to enclose text in literal $
characters, backslash-escape them and
they won’t be treated as math delimiters.
TeX math will be printed in all output formats. How it is rendered depends on the output format:
Markdown, LaTeX, Org-Mode, ConTeXt
~ It will appear verbatim between $
characters.
reStructuredText
~ It will be rendered using an interpreted text role :math:
, as
described
here.
AsciiDoc
~ It will be rendered as latexmath:[...]
.
Texinfo
~ It will be rendered inside a @math
command.
groff man
~ It will be rendered verbatim without $
’s.
MediaWiki
~ It will be rendered inside <math>
tags.
Textile
~ It will be rendered inside <span class="math">
tags.
RTF, OpenDocument, ODT ~ It will be rendered, if possible, using unicode characters, and will otherwise appear verbatim.
Docbook
~ If the --mathml
flag is used, it will be rendered using mathml in
an inlineequation
or informalequation
tag. Otherwise it will be
rendered, if possible, using unicode characters.
Docx ~ It will be rendered using OMML math markup.
FictionBook2
~ If the --webtex
option is used, formulas are rendered as images
using Google Charts or other compatible web service, downloaded and
embedded in the e-book. Otherwise, they will appear verbatim.
HTML, Slidy, DZSlides, S5, EPUB ~ The way math is rendered in HTML will depend on the command-line options selected:
1. The default is to render TeX math as far as possible using
unicode characters, as with RTF, DocBook, and OpenDocument
output. Formulas are put inside a `span` with `class="math"`, so
that they may be styled differently from the surrounding text if
needed.
2. If the `--latexmathml` option is used, TeX math will be
displayed between `$` or `$$` characters and put in `<span>`
tags with class `LaTeX`. The
[LaTeXMathML](http://math.etsu.edu/LaTeXMathML/) script will be
used to render it as formulas. (This trick does not work in all
browsers, but it works in Firefox. In browsers that do not
support LaTeXMathML, TeX math will appear verbatim between `$`
characters.)
3. If the `--jsmath` option is used, TeX math will be put inside
`<span>` tags (for inline math) or `<div>` tags (for display
math) with class `math`. The
[jsMath](http://www.math.union.edu/~dpvc/jsmath/) script will be
used to render it.
4. If the `--mimetex` option is used, the
[mimeTeX](http://www.forkosh.com/mimetex.html) CGI script will
be called to generate images for each TeX formula. This should
work in all browsers. The `--mimetex` option takes an optional
URL as argument. If no URL is specified, it will be assumed that
the mimeTeX CGI script is at `/cgi-bin/mimetex.cgi`.
5. If the `--gladtex` option is used, TeX formulas will be enclosed
in `<eq>` tags in the HTML output. The resulting `htex` file may
then be processed by
[gladTeX](http://ans.hsh.no/home/mgg/gladtex/), which will
produce image files for each formula and an `html` file with
links to these images. So, the procedure is:
pandoc -s --gladtex myfile.txt -o myfile.htex
gladtex -d myfile-images myfile.htex
# produces myfile.html and images in myfile-images
6. If the `--webtex` option is used, TeX formulas will be converted
to `<img>` tags that link to an external script that converts
formulas to images. The formula will be URL-encoded and
concatenated with the URL provided. If no URL is specified, the
Google Chart API will be used
(`http://chart.apis.google.com/chart?cht=tx&chl=`).
7. If the `--mathjax` option is used, TeX math will be displayed
between `\(...\)` (for inline math) or `\[...\]` (for display
math) and put in `<span>` tags with class `math`. The
[MathJax](http://www.mathjax.org/) script will be used to render
it as formulas.
Raw HTML
[raw-html]
Extension: raw_html
Markdown allows you to insert raw HTML (or DocBook) anywhere in a
document (except verbatim contexts, where <
, >
, and &
are
interpreted literally). (Technically this is not an extension, since
standard markdown allows it, but it has been made an extension so that
it can be disabled if desired.)
The raw HTML is passed through unchanged in HTML, S5, Slidy, Slideous, DZSlides, EPUB, Markdown, and Textile output, and suppressed in other formats.
Extension: markdown_in_html_blocks
Standard markdown allows you to include HTML “blocks”: blocks of HTML
between balanced tags that are separated from the surrounding text with
blank lines, and start and end at the left margin. Within these blocks,
everything is interpreted as HTML, not markdown; so (for example), *
does not signify emphasis.
Pandoc behaves this way when the markdown_strict
format is used; but
by default, pandoc interprets material between HTML block tags as
markdown. Thus, for example, Pandoc will turn
<table>
<tr>
<td>*one*</td>
<td>[a link](http://google.com)</td>
</tr>
</table>
into
<table>
<tr>
<td><em>one</em></td>
<td><a href="http://google.com">a link</a></td>
</tr>
</table>
whereas Markdown.pl
will preserve it as is.
There is one exception to this rule: text between <script>
and
<style>
tags is not interpreted as markdown.
This departure from standard markdown should make it easier to mix
markdown with HTML block elements. For example, one can surround a block
of markdown text with <div>
tags without preventing it from being
interpreted as markdown.
Raw TeX
[raw-tex]
Extension: raw_tex
In addition to raw HTML, pandoc allows raw LaTeX, TeX, and ConTeXt to be included in a document. Inline TeX commands will be preserved and passed unchanged to the LaTeX and ConTeXt writers. Thus, for example, you can use LaTeX to include BibTeX citations:
This result was proved in \cite{jones.1967}.
Note that in LaTeX environments, like
\begin{tabular}{|l|l|}\hline
Age & Frequency \\ \hline
18--25 & 15 \\
26--35 & 33 \\
36--45 & 22 \\ \hline
\end{tabular}
the material between the begin and end tags will be interpreted as raw LaTeX, not as markdown.
Inline LaTeX is ignored in output formats other than Markdown, LaTeX, and ConTeXt.
LaTeX macros
[latex-macros]
Extension: latex_macros
For output formats other than LaTeX, pandoc will parse LaTeX
\newcommand
and \renewcommand
definitions and apply the resulting
macros to all LaTeX math. So, for example, the following will work in
all output formats, not just LaTeX:
\newcommand{\tuple}[1]{\langle #1 \rangle}
$\tuple{a, b, c}$
In LaTeX output, the \newcommand
definition will simply be passed
unchanged to the output.
Links
[links]
Markdown allows links to be specified in several ways.
Automatic links
[automatic-links]
If you enclose a URL or email address in pointy brackets, it will become a link:
<http://google.com>
<sam@green.eggs.ham>
Inline links
[inline-links]
An inline link consists of the link text in square brackets, followed by the URL in parentheses. (Optionally, the URL can be followed by a link title, in quotes.)
This is an [inline link](/url), and here's [one with
a title](http://fsf.org "click here for a good time!").
There can be no space between the bracketed part and the parenthesized part. The link text can contain formatting (such as emphasis), but the title cannot.
Reference links
[reference-links]
An explicit reference link has two parts, the link itself and the link definition, which may occur elsewhere in the document (either before or after the link).
The link consists of link text in square brackets, followed by a label in square brackets. (There can be space between the two.) The link definition consists of the bracketed label, followed by a colon and a space, followed by the URL, and optionally (after a space) a link title either in quotes or in parentheses.
Here are some examples:
[my label 1]: /foo/bar.html "My title, optional"
[my label 2]: /foo
[my label 3]: http://fsf.org (The free software foundation)
[my label 4]: /bar#special 'A title in single quotes'
The URL may optionally be surrounded by angle brackets:
[my label 5]: <http://foo.bar.baz>
The title may go on the next line:
[my label 3]: http://fsf.org
"The free software foundation"
Note that link labels are not case sensitive. So, this will work:
Here is [my link][FOO]
[Foo]: /bar/baz
In an implicit reference link, the second pair of brackets is empty, or omitted entirely:
See [my website][], or [my website].
[my website]: http://foo.bar.baz
Note: In Markdown.pl
and most other markdown implementations,
reference link definitions cannot occur in nested constructions such as
list items or block quotes. Pandoc lifts this arbitrary seeming
restriction. So the following is fine in pandoc, though not in most
other implementations:
> My block [quote].
>
> [quote]: /foo
Internal links
[internal-links]
To link to another section of the same document, use the automatically generated identifier (see [header-identifiers-in-html-latex-and-context]Header identifiers in HTML, LaTeX, and ConTeXt, below). For example:
See the [Introduction](#introduction).
or
See the [Introduction].
[Introduction]: #introduction
Internal links are currently supported for HTML formats (including HTML slide shows and EPUB), LaTeX, and ConTeXt.
Images
[images]
A link immediately preceded by a !
will be treated as an image. The
link text will be used as the image’s alt text:
![la lune](lalune.jpg "Voyage to the moon")
![movie reel]
[movie reel]: movie.gif
Pictures with captions
[pictures-with-captions]
Extension: implicit_figures
An image occurring by itself in a paragraph will be rendered as a figure
with a caption.4 (In LaTeX, a figure environment will be used; in
HTML, the image will be placed in a div
with class figure
, together
with a caption in a p
with class caption
.) The image’s alt text will
be used as the caption.
![This is the caption](/url/of/image.png)
If you just want a regular inline image, just make sure it is not the only thing in the paragraph. One way to do this is to insert a nonbreaking space after the image:
![This image won't be a figure](/url/of/image.png)\
Footnotes
[footnotes]
Extension: footnotes
Pandoc’s markdown allows footnotes, using the following syntax:
Here is a footnote reference,[^1] and another.[^longnote]
[^1]: Here is the footnote.
[^longnote]: Here's one with multiple blocks.
Subsequent paragraphs are indented to show that they
belong to the previous footnote.
{ some.code }
The whole paragraph can be indented, or just the first
line. In this way, multi-paragraph footnotes work like
multi-paragraph list items.
This paragraph won't be part of the note, because it
isn't indented.
The identifiers in footnote references may not contain spaces, tabs, or newlines. These identifiers are used only to correlate the footnote reference with the note itself; in the output, footnotes will be numbered sequentially.
The footnotes themselves need not be placed at the end of the document. They may appear anywhere except inside other block elements (lists, block quotes, tables, etc.).
Extension: inline_notes
Inline footnotes are also allowed (though, unlike regular notes, they cannot contain multiple paragraphs). The syntax is as follows:
Here is an inline note.^[Inlines notes are easier to write, since
you don't have to pick an identifier and move down to type the
note.]
Inline and regular footnotes may be mixed freely.
Citations
[citations]
Extension: citations
Using an external filter, pandoc-citeproc
, pandoc can automatically
generate citations and a bibliography in a number of styles. Basic usage
is
pandoc --filter pandoc-citeproc myinput.txt
In order to use this feature, you will need to specify a bibliography
file using the bibliography
metadata field in a YAML metadata section.
The bibliography may have any of these formats:
[c]@ll@ Format & File extension\ MODS & .mods\ BibLaTeX & .bib\ BibTeX & .bibtex\ RIS & .ris\ EndNote & .enl\ EndNote XML & .xml\ ISI & .wos\ MEDLINE & .medline\ Copac & .copac\ JSON citeproc & .json\
Note that .bib
can generally be used with both BibTeX and BibLaTeX
files, but you can use .bibtex
to force BibTeX.
Alternatively you can use a references
field in the document’s YAML
metadata. This should include an array of YAML-encoded references, for
example:
---
references:
- id: fenner2012a
title: One-click science marketing
author:
- family: Fenner
given: Martin
container-title: Nature Materials
volume: 11
URL: 'http://dx.doi.org/10.1038/nmat3283'
DOI: 10.1038/nmat3283
issue: 4
publisher: Nature Publishing Group
page: 261-263
type: article-journal
issued:
year: 2012
month: 3
...
(The program mods2yaml
, which comes with pandoc-citeproc
, can help
produce these from a MODS reference collection.)
By default, pandoc-citeproc
will use a Chicago author-date format for
citations and references. To use another style, you will need to specify
a CSL 1.0 style file in the csl
metadata
field. A primer on creating and modifying CSL styles can be found at
http://citationstyles.org/downloads/primer.html. A repository of CSL
styles can be found at
https://github.com/citation-style-language/styles. See also
http://zotero.org/styles for easy browsing.
Citations go inside square brackets and are separated by semicolons.
Each citation must have a key, composed of ‘@’ + the citation identifier
from the database, and may optionally have a prefix, a locator, and a
suffix. The citation key must begin with a letter or _
, and may
contain alphanumerics, _
, and internal punctuation characters
(:.#$%&-+?<>/
). Here are some examples:
Blah blah [see @doe99, pp. 33-35; also @smith04, ch. 1].
Blah blah [@doe99, pp. 33-35, 38-39 and *passim*].
Blah blah [@smith04; @doe99].
A minus sign (-
) before the @
will suppress mention of the author in
the citation. This can be useful when the author is already mentioned in
the text:
Smith says blah [-@smith04].
You can also write an in-text citation, as follows:
@smith04 says blah.
@smith04 [p. 33] says blah.
If the style calls for a list of works cited, it will be placed at the end of the document. Normally, you will want to end your document with an appropriate header:
last paragraph...
# References
The bibliography will be inserted after this header. Note that the
unnumbered
class will be added to this header, so that the section
will not be numbered.
If you want to include items in the bibliography without actually citing
them in the body text, you can define a dummy nocite
metadata field
and put the citations there:
---
nocite: |
@item1, @item2
...
@item3
In this example, the document will contain a citation for item3
only,
but the bibliography will contain entries for item1
, item2
, and
item3
.
Non-pandoc extensions
[non-pandoc-extensions]
The following markdown syntax extensions are not enabled by default in
pandoc, but may be enabled by adding +EXTENSION
to the format name,
where EXTENSION
is the name of the extension. Thus, for example,
markdown+hard_line_breaks
is markdown with hard line breaks.
Extension: lists_without_preceding_blankline
\
Allow a list to occur right after a paragraph, with no intervening blank
space.
Extension: hard_line_breaks
\
Causes all newlines within a paragraph to be interpreted as hard line
breaks instead of spaces.
Extension: ignore_line_breaks
\
Causes newlines within a paragraph to be ignored, rather than being
treated as spaces or as hard line breaks. This option is intended for
use with East Asian languages where spaces are not used between words,
but text is divided into lines for readability.
Extension: tex_math_single_backslash
\
Causes anything between \(
and \)
to be interpreted as inline TeX
math, and anything between \[
and \]
to be interpreted as display
TeX math. Note: a drawback of this extension is that it precludes
escaping (
and [
.
Extension: tex_math_double_backslash
\
Causes anything between \\(
and \\)
to be interpreted as inline TeX
math, and anything between \\[
and \\]
to be interpreted as display
TeX math.
Extension: markdown_attribute
\
By default, pandoc interprets material inside block-level tags as
markdown. This extension changes the behavior so that markdown is only
parsed inside block-level tags if the tags have the attribute
markdown=1
.
Extension: mmd_title_block
\
Enables a MultiMarkdown
style title block at the top of the document, for example:
Title: My title
Author: John Doe
Date: September 1, 2008
Comment: This is a sample mmd title block, with
a field spanning multiple lines.
See the MultiMarkdown documentation for details. If pandoc_title_block
or yaml_metadata_block
is enabled, it will take precedence over
mmd_title_block
.
Extension: abbreviations
\
Parses PHP Markdown Extra abbreviation keys, like
*[HTML]: Hyper Text Markup Language
Note that the pandoc document model does not support abbreviations, so if this extension is enabled, abbreviation keys are simply skipped (as opposed to being parsed as paragraphs).
Extension: autolink_bare_uris
\
Makes all absolute URIs into links, even when not surrounded by pointy
braces <...>
.
Extension: ascii_identifiers
\
Causes the identifiers produced by auto_identifiers
to be pure ASCII.
Accents are stripped off of accented latin letters, and non-latin
letters are omitted.
Extension: link_attributes
\
Parses multimarkdown style key-value attributes on link and image
references. Note that pandoc’s internal document model provides nowhere
to put these, so they are presently just ignored.
Extension: mmd_header_identifiers
\
Parses multimarkdown style header identifiers (in square brackets, after
the header but before any trailing #
s in an ATX header).

Extensions with formats other than markdown
[extensions-with-formats-other-than-markdown]
Some of the extensions discussed above can be used with formats other than markdown:
-
auto_identifiers
can be used withlatex
,rst
,mediawiki
, andtextile
input (and is used by default). -
tex_math_dollars
,tex_math_single_backslash
, andtex_math_double_backslash
can be used withhtml
input. (This is handy for reading web pages formatted using MathJax, for example.)
Producing slide shows with Pandoc
[producing-slide-shows-with-pandoc]
You can use Pandoc to produce an HTML + javascript slide presentation that can be viewed via a web browser. There are five ways to do this, using S5, DZSlides, Slidy, Slideous, or reveal.js. You can also produce a PDF slide show using LaTeX beamer.
Here’s the markdown source for a simple slide show, habits.txt
:
% Habits
% John Doe
% March 22, 2005
# In the morning
## Getting up
- Turn off alarm
- Get out of bed
## Breakfast
- Eat eggs
- Drink coffee
# In the evening
## Dinner
- Eat spaghetti
- Drink wine
------------------
![picture of spaghetti](images/spaghetti.jpg)
## Going to sleep
- Get in bed
- Count sheep
To produce an HTML/javascript slide show, simply type
pandoc -t FORMAT -s habits.txt -o habits.html
where FORMAT
is either s5
, slidy
, slideous
, dzslides
, or
revealjs
.
For Slidy, Slideous, reveal.js, and S5, the file produced by pandoc with
the -s/--standalone
option embeds a link to javascripts and CSS files,
which are assumed to be available at the relative path s5/default
(for
S5), slideous
(for Slideous), reveal.js
(for reveal.js), or at the
Slidy website at w3.org
(for Slidy). (These paths can be changed by
setting the slidy-url
, slideous-url
, revealjs-url
, or s5-url
variables; see --variable
, above.) For DZSlides, the (relatively
short) javascript and css are included in the file by default.
With all HTML slide formats, the --self-contained
option can be used
to produce a single file that contains all of the data necessary to
display the slide show, including linked scripts, stylesheets, images,
and videos.
To produce a PDF slide show using beamer, type
pandoc -t beamer habits.txt -o habits.pdf
Note that a reveal.js slide show can also be converted to a PDF by printing it to a file from the browser.
By default, the slide level is the highest header level in the
hierarchy that is followed immediately by content, and not another
header, somewhere in the document. In the example above, level 1 headers
are always followed by level 2 headers, which are followed by content,
so 2 is the slide level. This default can be overridden using the
--slide-level
option.
The document is carved up into slides according to the following rules:
-
A horizontal rule always starts a new slide.
-
A header at the slide level always starts a new slide.
-
Headers below the slide level in the hierarchy create headers within a slide.
-
Headers above the slide level in the hierarchy create “title slides,” which just contain the section title and help to break the slide show into sections.
-
A title page is constructed automatically from the document’s title block, if present. (In the case of beamer, this can be disabled by commenting out some lines in the default template.)
These rules are designed to support many different styles of slide show. If you don’t care about structuring your slides into sections and subsections, you can just use level 1 headers for all each slide. (In that case, level 1 will be the slide level.) But you can also structure the slide show into sections, as in the example above.
Note: in reveal.js slide shows, if slide level is 2, a two-dimensional layout will be produced, with level 1 headers building horizontally and level 2 headers building vertically. It is not recommended that you use deeper nesting of section levels with reveal.js.
Incremental lists
[incremental-lists]
By default, these writers produces lists that display “all at once.” If
you want your lists to display incrementally (one item at a time), use
the -i
option. If you want a particular list to depart from the
default (that is, to display incrementally without the -i
option and
all at once with the -i
option), put it in a block quote:
> - Eat spaghetti
> - Drink wine
In this way incremental and nonincremental lists can be mixed in a single document.
Inserting pauses
[inserting-pauses]
You can add “pauses” within a slide by including a paragraph containing three dots, separated by spaces:
# Slide with a pause
content before the pause
. . .
content after the pause
Styling the slides
[styling-the-slides]
You can change the style of HTML slides by putting customized CSS files
in $DATADIR/s5/default
(for S5), $DATADIR/slidy
(for Slidy), or
$DATADIR/slideous
(for Slideous), where $DATADIR
is the user data
directory (see --data-dir
, above). The originals may be found in
pandoc’s system data directory (generally
$CABALDIR/pandoc-VERSION/s5/default
). Pandoc will look there for any
files it does not find in the user data directory.
For dzslides, the CSS is included in the HTML file itself, and may be modified there.
For reveal.js, themes can be used by setting the theme
variable, for
example:
-V theme=moon
Or you can specify a custom stylesheet using the --css
option.
To style beamer slides, you can specify a beamer “theme” or “colortheme”
using the -V
option:
pandoc -t beamer habits.txt -V theme:Warsaw -o habits.pdf
Note that header attributes will turn into slide attributes (on a
<div>
or <section>
) in HTML slide formats, allowing you to style
individual slides. In Beamer, the only header attribute that affects
slides is the allowframebreaks
class, which sets the
allowframebreaks
option, causing multiple slides to be created if the
content overfills the frame. This is recommended especially for
bibliographies:
# References {.allowframebreaks}
Speaker notes
[speaker-notes]
reveal.js has good support for speaker notes. You can add notes to your markdown document thus:
<div class="notes">
This is my note.
- It can contain markdown
- like this list
</div>
To show the notes window, press s
while viewing the presentation.
Notes are not yet supported for other slide formats, but the notes will
not appear on the slides themselves.
EPUB metadata may be specified using the --epub-metadata
option, but
if the source document is markdown, it is better to use a YAML metadata
block. Here is an example:
---
title:
- type: main
text: My Book
- type: subtitle
text: An investigation of metadata
creator:
- role: author
text: John Smith
- role: editor
text: Sarah Jones
identifier:
- scheme: DOI
text: doi:10.234234.234/33

If you append +lhs
(or +literate_haskell
) to an appropriate input or
output format (markdown
, markdown_strict
, rst
, or latex
for
input or output; beamer
, html
or html5
for output only), pandoc
will treat the document as literate Haskell source. This means that
-
In markdown input, “bird track” sections will be parsed as Haskell code rather than block quotations. Text between
\begin{code}
and\end{code}
will also be treated as Haskell code. -
In markdown output, code blocks with classes
haskell
andliterate
will be rendered using bird tracks, and block quotations will be indented one space, so they will not be treated as Haskell code. In addition, headers will be rendered setext-style (with underlines) rather than atx-style (with ‘#’ characters). (This is because ghc treats ‘#’ characters in column 1 as introducing line numbers.) -
In restructured text input, “bird track” sections will be parsed as Haskell code.
-
In restructured text output, code blocks with class
haskell
will be rendered using bird tracks. -
In LaTeX input, text in
code
environments will be parsed as Haskell code. -
In LaTeX output, code blocks with class
haskell
will be rendered insidecode
environments. -
In HTML output, code blocks with class
haskell
will be rendered with classliteratehaskell
and bird tracks.
Examples:
pandoc -f markdown+lhs -t html
reads literate Haskell source formatted with markdown conventions and writes ordinary HTML (without bird tracks).
pandoc -f markdown+lhs -t html+lhs
writes HTML with the Haskell code in bird tracks, so it can be copied and pasted as literate Haskell source.
Pandoc can be extended with custom writers written in lua. (Pandoc includes a lua interpreter, so lua need not be installed separately.)
To use a custom writer, simply specify the path to the lua script in place of the output format. For example:
pandoc -t data/sample.lua
Creating a custom writer requires writing a lua function for each possible element in a pandoc document. To get a documented example which you can modify according to your needs, do
pandoc --print-default-data-file sample.lua

The point of this rule is to ensure that normal paragraphs starting with people’s initials, like
B. Russell was an English philosopher.
do not get treated as list items.
This rule will not prevent
(C) 2007 Joe Smith
from being interpreted as a list item. In this case, a backslash escape can be used:
