NAME

       pandoc - general markup converter

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.  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.

   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,   pdfroff,   or   any   of   the  following
       HTML/CSS-to-PDF-engines, to create a PDF: wkhtmltopdf, weasyprint or prince.  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   (-t html   defaults   to
       --pdf-engine=wkhtmltopdf).

       PDF  output  can  be controlled using variables for LaTeX (if LaTeX is used) and variables
       for ConTeXt (if ConTeXt is used).  When using an HTML/CSS-to-PDF-engine, --css affects the
       output.  If wkhtmltopdf is used, then the variables margin-left, margin-right, margin-top,
       margin-bottom, footer-html, header-html and papersize will affect the output.

       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  and
       grffile  (if  the  document  contains  images),  hyperref, xcolor (with colorlinks), ulem,
       geometry (with the geometry variable set), setspace (with linestretch),  and  babel  (with
       lang).   The  use  of  xelatex or lualatex as the LaTeX engine requires fontspec.  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
       added  to  the template or included in any header file.  The natbib, biblatex, bibtex, and
       biber packages can optionally be used for citation rendering.

   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 http://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" \
                http://www.fsf.org

              Note that odt, docx, and epub 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.  This is, in UNIX:

                     $HOME/.pandoc

              in Windows XP:

                     C:\Documents And Settings\USERNAME\Application Data\pandoc

              and in Windows Vista or later:

                     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.

       --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.  Currently this only has an effect with PDF 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, 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
       --base-header-level=NUMBER
              Specify the base level for headers (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.

       --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.

       --lua-filter=SCRIPT
              Transform the document in a similar fashion as JSON filters (see --filter), but use
              pandoc's build-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.   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.

       -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).

       --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), inserts all insertions, and
              ignores all deletions.  reject inserts all deletions and ignores insertions.   Both
              accept  and  reject  ignore  comments.   all  puts  in  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
       -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
              Use  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.  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  system  default  template  for an output FORMAT.  (See -t for a list of
              possible FORMATs.) Templates in the user data directory are ignored.

       --print-default-data-file=FILE
              Print a system default data file.  Files in the user data directory are ignored.

       --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  dpi  (dots  per  inch)  value   for   conversion   from   pixels   to
              inch/centimeters  and  vice versa.  The default is 96dpi.  Technically, the correct
              term would be ppi (pixels per inch).

       --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.

       --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 on man,  docbook4,  docbook5,  or  jats
              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).

       --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.

       --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.

       -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
              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.

       --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).

   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.
              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.

       --ascii
              Use  only ASCII characters in output.  Currently supported for XML and HTML formats
              (which use numerical entities instead of UTF-8 when this option  is  selected)  and
              for groff ms and man (which use hexadecimal escapes).

       --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.

       --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.  (Note: for gfm  output,
              ATX headers are always used.)

       --top-level-division=[default|section|chapter|part]
              Treat  top-level headers as the given division type in LaTeX, ConTeXt, DocBook, and
              TEI output.  The hierarchy order is part, chapter, then section;  all  headers  are
              shifted  such  that  the  top-level header 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 LaTeX document class 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  headers  to  become  \part{..},  while
              second-level headers remain as their default type.

       -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.

       --listings
              Use the 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.  Note that content that is not contained under slide-level  headers
              will  not appear in the slide show.  The default is to set the slide level based on
              the contents of the document; see Structuring the slide show.

       --section-divs
              Wrap sections in <section> tags (or <div> tags for html4), and  attach  identifiers
              to  the  enclosing  <section> (or <div>) rather than the header itself.  See Header
              identifiers, below.

       --email-obfuscation=none|javascript|references
              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.  The default is none.

       --id-prefix=STRING
              Specify  a  prefix  to  be  added to all identifiers and internal links in HTML and
              DocBook output, and to footnote numbers in Markdown and Haddock  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 used repeatedly to include  multiple
              files.  They will be included in the order specified.

              A  stylesheet  is  required  for  generating  EPUB.  If none is provided using this
              option (or the stylesheet metadata field), 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.

       --reference-doc=FILE
              Use the specified file as a style reference in producing a docx or ODT file.

              Docx   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 and document properties (including margins,  page  size,
                     header,  and  footer)  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.

                     To produce a  custom  reference.docx,  first  get  a  copy  of  the  default
                     reference.docx:
                     pandoc --print-default-data-file reference.docx > custom-reference.docx.
                     Then  open custom-reference.docx in Word, modify the styles as you wish, and
                     save the file.  For best results, do not make changes  to  this  file  other
                     than  modifying  the  styles  used by pandoc: [paragraph] Normal, Body Text,
                     First  Paragraph,  Compact,  Title,  Subtitle,   Author,   Date,   Abstract,
                     Bibliography, Heading 1, Heading 2, Heading 3, Heading 4, Heading 5, Heading
                     6, Heading 7, Heading 8, Heading 9, Block Text,  Footnote  Text,  Definition
                     Term,  Definition,  Caption, Table Caption, Image Caption, Figure, Captioned
                     Figure, TOC Heading; [character] Default Paragraph  Font,  Body  Text  Char,
                     Verbatim Char, Footnote Reference, Hyperlink; [table] Table.

              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.

                     To produce  a  custom  reference.odt,  first  get  a  copy  of  the  default
                     reference.odt:
                     pandoc --print-default-data-file reference.odt > custom-reference.odt.  Then
                     open custom-reference.odt in LibreOffice, modify the styles as you wish, and
                     save the file.

              PowerPoint
                     Any template included with a recent install of Microsoft PowerPoint  (either
                     with  .pptx  or .potx extension) should work, as will most templates derived
                     from these.

                     The specific requirement is that the template should contain  the  following
                     four layouts as its first four layouts:

                     1. Title Slide

                     2. Title and Content

                     3. Section Header

                     4. Two Content

                     All templates included with a recent version of MS PowerPoint will fit these
                     criteria.  (You can click on Layout under the Home menu to check.)

                     You   can   also   modify   the   default    reference.pptx:    first    run
                     pandoc --print-default-data-file reference.pptx > custom-reference.pptx, and
                     then modify custom-reference.pptx in MS  PowerPoint  (pandoc  will  use  the
                     first four layout slides, as mentioned above).

       --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, 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.  For example:

                      <dc:rights>Creative Commons</dc:rights>
                      <dc:language>es-AR</dc:language>

              By default, pandoc will include the following metadata elements:  <dc:title>  (from
              the  document title), <dc:creator> (from the document authors), <dc:date> (from the
              document date, which should be in ISO 8601 format), <dc:language>  (from  the  lang
              variable,  or,  if  is  not  set,  the  locale), and <dc:identifier id="BookId"> (a
              randomly generated UUID).  Any of these  may  be  overridden  by  elements  in  the
              metadata file.

              Note: if the source document is Markdown, a YAML metadata block in the document can
              be used instead.  See below under EPUB Metadata.

       --epub-embed-font=FILE
              Embed the specified font in the  EPUB.   This  option  can  be  repeated  to  embed
              multiple  fonts.   Wildcards  can  also  be  used:  for  example, DejaVuSans-*.ttf.
              However, if you use wildcards on the command line, be sure to escape  them  or  put
              the  whole filename in single quotes, to prevent them from being interpreted by the
              shell.  To use the embedded fonts, you will  need  to  add  declarations  like  the
              following to your CSS (see --css):

                     @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.

       --epub-subdirectory=DIRNAME
              Specify the subdirectory in the OCF container that is  to  hold  the  EPUB-specific
              contents.   The default is EPUB.  To put the EPUB contents in the top level, use an
              empty string.

       --pdf-engine=pdflatex|lualatex|xelatex|wkhtmltopdf|weasyprint|prince|context|pdfroff
              Use the specified 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.

       --pdf-engine-opt=STRING
              Use  the  given  string  as  a  command-line  argument  to the pdf-engine.  If used
              multiple times, the arguments are provided with spaces between them.  Note that  no
              check for duplicate options is done.

   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.)  If --natbib
              or --biblatex is also supplied, pandoc-citeproc is not used, making this equivalent
              to  --metadata bibliography=FILE.  If you supply this argument multiple times, each
              FILE will be added to bibliography.

       --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.) This option is only
              relevant with pandoc-citeproc.

       --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.)  This  option  is   only   relevant   with
              pandoc-citeproc.

       --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 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 bibtex or biber.

   Math rendering in HTML
       The  default  is to render TeX math as far as possible using Unicode characters.  Formulas
       are put inside a span with class="math", so that they may be styled differently  from  the
       surrounding  text  if needed.  However, this gives acceptable results only for basic math,
       usually you will want to use --mathjax or another of the following options.

       --mathjax[=URL]
              Use MathJax to display embedded TeX math in HTML output.   TeX  math  will  be  put
              between  \(...\)  (for  inline  math)  or \[...\] (for display math) and wrapped in
              <span> tags with class math.  Then the MathJax JavaScript will render it.  The  URL
              should  point  to  the MathJax.js load script.  If a URL is not provided, a link to
              the Cloudflare CDN will be inserted.

       --mathml
              Convert TeX math to MathML (in epub3, docbook4, docbook5, jats, html4  and  html5).
              This  is  the  default  in odt output.  Note that currently only Firefox and Safari
              (and select e-book readers) natively support MathML.

       --webtex[=URL]
              Convert TeX formulas 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.      For     SVG     images     you     can     for      example      use
              --webtex https://latex.codecogs.com/svg.latex?.    If  no  URL  is  specified,  the
              CodeCogs URL generating PNGs will be used  (https://latex.codecogs.com/png.latex?).
              Note:  the  --webtex  option  will affect Markdown output as well as HTML, which is
              useful if you're targeting a version of Markdown without native math support.

       --katex[=URL]
              Use KaTeX to display embedded TeX math in HTML output.  The URL is the base URL for
              the  KaTeX  library.   If  a  URL  is not provided, a link to the KaTeX CDN will be
              inserted.

       --katex-stylesheet=URL
              The URL should point to the katex.css stylesheet.  If this option is not specified,
              a  link  to  the  KaTeX CDN will be inserted.  Note that this option does not imply
              --katex.

       --gladtex
              Enclose TeX math in <eq> tags in HTML output.   The  resulting  HTML  can  then  be
              processed  by  GladTeX  to  produce images of the typeset formulas and an HTML file
              with links to these images.  So, the procedure is:

                     pandoc -s --gladtex input.md -o myfile.htex
                     gladtex -d myfile-images myfile.htex
                     # produces myfile.html and images in myfile-images

   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

TEMPLATES

       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 (or the  default.context  template,
         if you use -t context, or the default.ms template, if you use -t ms, or the default.html
         template, if you use -t html).

       · docx has no template (however, you can use --reference-doc to customize the output).

       Templates contain variables, which allow for the inclusion of arbitrary information at any
       point  in  the  file.  They may be set at the command line using the -V/--variable option.
       If a variable is not set, pandoc will look for the key in the document's metadata –  which
       can be set using either YAML metadata blocks or with the --metadata option.

   Variables set by pandoc
       Some  variables  are  set  automatically  by pandoc.  These vary somewhat depending on the
       output format, but include the following:

       sourcefile, outputfile
              source and destination filenames, as given on the  command  line.   sourcefile  can
              also be a list if input comes from multiple files, or empty if input is from stdin.
              You can use the following snippet in your template to distinguish them:

                     $if(sourcefile)$
                     $for(sourcefile)$
                     $sourcefile$
                     $endfor$
                     $else$
                     (stdin)
                     $endif$

              Similarly, outputfile can be - if output goes to the terminal.

       title, author, date
              allow identification of basic aspects of the document.  Included  in  PDF  metadata
              through  LaTeX  and  ConTeXt.  These can be set through a pandoc title block, which
              allows for multiple authors, or through a YAML metadata block:

                     ---
                     author:
                     - Aristotle
                     - Peter Abelard
                     ...

       subtitle
              document subtitle, included in HTML, EPUB, LaTeX, ConTeXt, and Word  docx;  renders
              in  LaTeX  only when using a document class that supports \subtitle, such as beamer
              or the KOMA-Script series (scrartcl, scrreprt, scrbook).

       institute
              author affiliations (in LaTeX and Beamer only).  Can be  a  list,  when  there  are
              multiple authors.

       abstract
              document summary, included in LaTeX, ConTeXt, AsciiDoc, and Word docx

       keywords
              list  of  keywords  to  be  included  in  HTML,  PDF, and AsciiDoc metadata; may be
              repeated as for author, above

       header-includes
              contents specified by -H/--include-in-header (may have multiple values)

       toc    non-null value if --toc/--table-of-contents was specified

       toc-title
              title of table of contents (works only with EPUB, opendocument, odt, docx, pptx)

       include-before
              contents specified by -B/--include-before-body (may have multiple values)

       include-after
              contents specified by -A/--include-after-body (may have multiple values)

       body   body of document

       meta-json
              JSON  representation  of  all  of  the  document's  metadata.   Field  values   are
              transformed to the selected output format.

   Language variables
       lang   identifies  the  main  language  of  the document, using a code according to BCP 47
              (e.g.  en or en-GB).  For some  output  formats,  pandoc  will  convert  it  to  an
              appropriate  format stored in the additional variables babel-lang, polyglossia-lang
              (LaTeX) and context-lang (ConTeXt).

              Native pandoc Spans and Divs with the lang attribute (value in BCP 47) can be  used
              to  switch  the  language  in  that  range.   In LaTeX output, babel-otherlangs and
              polyglossia-otherlangs variables will be generated automatically based on the  lang
              attributes of Spans and Divs in the document.

       dir    the   base   direction   of   the  document,  either  rtl  (right-to-left)  or  ltr
              (left-to-right).

              For bidirectional documents, native pandoc spans and divs with  the  dir  attribute
              (value  rtl  or  ltr)  can  be  used  to override the base direction in some output
              formats.  This may not always  be  necessary  if  the  final  renderer  (e.g.   the
              browser, when generating HTML) supports the Unicode Bidirectional Algorithm.

              When  using  LaTeX  for  bidirectional  documents, only the xelatex engine is fully
              supported (use --pdf-engine=xelatex).

   Variables for slides

              must be available.

       mainfontoptions, sansfontoptions, monofontoptions, mathfontoptions, CJKoptions
              options  to use with mainfont, sansfont, monofont, mathfont, CJKmainfont in xelatex

              OpenType  features  Numbers=OldStyle,Numbers=Proportional.   May  be  repeated  for
              multiple options.

       fontenc
              allows font encoding to be  specified  through  fontenc  package  (with  pdflatex);
              default is T1 (see guide to LaTeX font encodings)

       microtypeoptions
              options to pass to the microtype package

       colorlinks
              add  color  to  link  text;  automatically  enabled if any of linkcolor, citecolor,
              urlcolor, or toccolor are set

       linkcolor, citecolor, urlcolor, toccolor
              color for internal links, citation links, external links, and  links  in  table  of

              x11names lists

       links-as-notes
              causes links to be printed as footnotes

       indent uses document class settings for indentation (the default LaTeX template  otherwise
              removes indentation and adds space between paragraphs)

       subparagraph
              disables  default  behavior  of  LaTeX  template  that redefines (sub)paragraphs as
              sections, changing the appearance of nested headings in some classes

       thanks specifies contents of acknowledgments footnote after document title.

       toc    include table of contents (can also be set using --toc/--table-of-contents)

       toc-depth

       lof, lot
              include list of figures, list of tables

       pdfa   adds  to  the  preamble  the  setup  necessary  to  generate   PDF/A-1b:2005.    To
              successfully  generate  PDF/A  the required ICC color profiles have to be available
              and the content and all included  files  (such  as  images)  have  to  be  standard
              conforming.   The ICC profiles can be obtained from ConTeXt ICC Profiles.  See also
              ConTeXt PDFA for more details.

       lineheight
              line height (e.g.  12p)

       fontfamily
              font family (e.g.  T or P)

       indent paragraph indent (e.g.  2m)

   Using variables in templates
       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 $$.

       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  truthy  value;  otherwise  it  will
       include Y.  Here a truthy value is any of the following:

       · a string that is not entirely white space,

       · a non-empty array where the first value is truthy,

       · any number (including zero),

       · any object,

       · the  boolean  true  (to  specify  the  boolean  true  value  using  YAML metadata or the
         --metadata flag, use y, Y, yes, Yes, YES, true, True, TRUE, on,  On,  or  ON;  with  the
         --variable flag, simply omit a value for the variable, e.g.  --variable draft).

       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 and  merge
       in changes after each pandoc release.

       Templates  may contain comments: anything on a line after $-- will be treated as a comment
       and ignored.

EXTENSIONS

       The behavior of some of the readers and writers can be adjusted by enabling  or  disabling
       various extensions.

       An extension can be enabled by adding +EXTENSION to the format name and disabled by adding
       -EXTENSION.   For  example,  --from markdown_strict+footnotes  is  strict  Markdown   with
       footnotes   enabled,  while  --from markdown-footnotes-pipe_tables  is  pandoc's  Markdown
       without footnotes or pipe tables.

       The markdown reader and writer make by far the most use of  extensions.   Extensions  only
       used  by  them  are therefore covered in the section Pandoc's Markdown below (See Markdown
       variants for commonmark and gfm.) In the following, extensions that also  work  for  other
       formats are covered.

   Typography
   Extension: smart
       Interpret  straight  quotes as curly quotes, --- as em-dashes, -- as en-dashes, and ... as
       ellipses.  Nonbreaking spaces are inserted after certain abbreviations, such as "Mr."

       This extension can be enabled/disabled for the following formats:

       input formats
              markdown, commonmark, latex, mediawiki, org, rst, twiki

       output formats
              markdown, latex, context, rst

       enabled by default in
              markdown, latex, context (both input and output)

       Note: If you are writing Markdown, then the smart extension has the reverse  effect:  what
       would have been curly quotes comes out straight.

       In LaTeX, smart means to use the standard TeX ligatures for quotation marks (`` and '' for
       double quotes, ` and ' for single quotes) and dashes (-- for en-dash and --- for em-dash).
       If  smart is disabled, then in reading LaTeX pandoc will parse these characters literally.
       In writing LaTeX, enabling smart tells pandoc to use the ligatures when possible; if smart
       is disabled pandoc will use unicode quotation mark and dash characters.

   Headers and sections
   Extension: auto_identifiers
       A  header  without  an  explicitly  specified  identifier will be automatically assigned a
       unique identifier based on the header text.

       This extension can be enabled/disabled for the following formats:

       input formats
              markdown, latex, rst, mediawiki, textile

       output formats
              markdown, muse

       enabled by default in
              markdown, muse

       The algorithm used to derive the identifier from the header text is:

       · 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,

       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  section
       (or  a  div, if html4 was specified), and the identifier will be attached to the enclosing
       <section> (or <div>) tag rather than the header itself.  This allows entire sections to be
       manipulated using JavaScript or treated differently in CSS.

   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.

   Math Input
       The extensions tex_math_dollars, tex_math_single_backslash, and  tex_math_double_backslash
       are described in the section about Pandoc's Markdown.

       However,  they  can  also  be  used  with HTML input.  This is handy for reading web pages
       formatted using MathJax, for example.

   Raw HTML/TeX
       The following extensions (especially how  they  affect  Markdown  input/output)  are  also
       described in more detail in their respective sections of Pandoc's Markdown.

   Extension: raw_html
       When  converting  from  HTML,  parse  elements  to raw HTML which are not representable in
       pandoc's AST.  By default, this is disabled for HTML input.

   Extension: raw_tex
       Allows raw LaTeX, TeX, and ConTeXt to be included in a document.

       This extension  can  be  enabled/disabled  for  the  following  formats  (in  addition  to
       markdown):

       input formats
              latex, org, textile

       output formats
              textile

   Extension: native_divs
       This  extension  is enabled by default for HTML input.  This means that divs are parsed to
       pandoc  native  elements.   (Alternatively,  you  can  parse  them  to  raw   HTML   using
       -f html-native_divs+raw_html.)

       When converting HTML to Markdown, for example, you may want to drop all divs and spans:

              pandoc -f html-native_divs-native_spans -t markdown

   Extension: native_spans
       Analogous to native_divs above.

   Literate Haskell support
   Extension: literate_haskell
       Treat the document as literate Haskell source.

       This extension can be enabled/disabled for the following formats:

       input formats
              markdown, rst, latex

       output formats
              markdown, rst, latex, html

       If  you  append +lhs (or +literate_haskell) to one of the formats above, 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.  For ATX-style headers the character '=' will be used instead of '#'.

       · In Markdown output, code blocks with classes haskell and literate 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  inside  code
         environments.

       · In  HTML  output,  code  blocks  with  class  haskell  will  be  rendered   with   class
         literatehaskell 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.

       Note  that  GHC  expects  the  bird  tracks in the first column, so indented literate code
       blocks (e.g.  inside an itemized environment)  will  not  be  picked  up  by  the  Haskell
       compiler.

   Other extensions
   Extension: empty_paragraphs
       Allows empty paragraphs.  By default empty paragraphs are omitted.

       This extension can be enabled/disabled for the following formats:

       input formats
              docx, html

       output formats
              docx, odt, opendocument, html

   Extension: styles
       Read  all  docx  styles  as  divs  (for paragraph styles) and spans (for character styles)
       regardless of whether pandoc understands the meaning of these styles.  This  can  be  used
       with docx custom styles.  Disabled by default.

       input formats
              docx

   Extension: amuse
       In the muse input format, this enables Text::Amuse extensions to Emacs Muse markup.

   Extension: citations
       Some aspects of Pandoc's Markdown citation syntax are also accepted in org input.

   Extension: ntb
       In the context output format this enables the use of Natural Tables (TABLE) instead of the
       default  Extreme  Tables  (xtables).   Natural  tables  allow  more  fine-grained   global
       customization but come at a performance penalty compared to extreme tables.

PANDOC'S MARKDOWN

       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.  Extensions can be enabled or disabled to specify the behavior
       more  granularly.   They  are  described in the following.  See also Extensions above, for
       extensions that work also on other formats.

   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
       A  paragraph  is  one or more lines of text followed by one or more blank lines.  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
       There are two kinds of headers: Setext and ATX.

   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,
       below).

   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: space_in_atx_header
       Many Markdown implementations do not require a space between the  opening  #s  of  an  ATX
       header  and  the  header  text,  so that #5 bolt and #hashtag count as headers.  With this
       extension, pandoc does require the space.

   Header identifiers
       See also the auto_identifiers extension above.

   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}

       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.)

       Note  that  although  this  syntax  allows assignment of classes and key/value attributes,
       writers generally don't use all of this information.  Identifiers, classes, and  key/value
       attributes  are  used  in HTML and HTML-based formats such as EPUB and slidy.  Identifiers
       are used for labels and link anchors in the LaTeX, ConTeXt, Textile, and AsciiDoc writers.

       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: implicit_header_references
       Pandoc behaves as if reference links have been defined for each header.  So, to link to  a
       header

              # Header identifiers in HTML

       you can simply write

              [Header identifiers in HTML]

       or

              [Header identifiers in HTML][]

       or

              [the section on header identifiers][header identifiers in
              HTML]

       instead of giving the identifier explicitly:

              [Header identifiers in HTML](#header-identifiers-in-html)

       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.

       Like regular reference links, these references are case-insensitive.

       Explicit  link reference definitions always take priority over implicit header references.
       So, in the following example, the link will point to bar, not to #foo:

              # Foo

              [foo]: bar

              See [foo]

   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 an optional 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.

       If the > character is followed by an optional space, that space will be considered part of
       the block quote marker and not part of the indentation of the contents.  Thus, to  put  an
       indented code block in a block quote, you need five spaces after the >:

              >     code

   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
   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.

   Fenced code blocks
   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 (~) and end with a row of tildes 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
              ~~~~~~~~~~
              ~~~~~~~~~~~~~~~~

   Extension: backtick_code_blocks
       Same as fenced_code_blocks, but uses backticks (`) instead of tildes (~).

   Extension: fenced_code_attributes
       Optionally, you may attach attributes to fenced or backtick 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,
       LaTeX, Docx, Ms, and PowerPoint.  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,  type  pandoc --list-highlight-languages.)  Otherwise,  the
       code block above will appear as follows:

              <pre id="mycode" class="haskell numberLines" startFrom="100">
                <code>
                ...
                </code>
              </pre>

       The  numberLines  (or  number-lines)  class  will  cause the lines of the code block to be
       numbered, starting with 1 or the value of the startFrom attribute.   The  lineAnchors  (or
       line-anchors) class will cause the lines to be clickable anchors in HTML output.

       A shortcut form can also be used for specifying the language of the code block:

              ```haskell
              qsort [] = []
              ```

       This is equivalent to:

              ``` {.haskell}
              qsort [] = []
              ```

       If the fenced_code_attributes extension is disabled, but input contains class attribute(s)
       for the code block, the first class attribute will be printed after the opening fence as a
       bare word.

       To  prevent all highlighting, use the --no-highlight flag.  To set the highlighting style,
       use --highlight-style.  For more information on  highlighting,  see  Syntax  highlighting,
       below.

   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
   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.

   Block content in list items
       A list item may contain multiple  paragraphs  and  other  block-level  content.   However,
       subsequent  paragraphs  must  be preceded by a blank line and indented to line up with the
       first non-space content after the list marker.

                * First paragraph.

                  Continued.

                * Second paragraph. With a code block, which must be indented
                  eight spaces:

                      { code }

       Exception: if the list marker is followed by an indented code block, which  must  begin  5
       spaces  after the list marker, then subsequent paragraphs must begin two columns after the
       last character of the list marker:

              *     code

                continuation paragraph

       List items may include other lists.  In this case the preceding blank  line  is  optional.
       The  nested  list must be indented to line up with the first non-space character after the
       list marker of the containing list item.

              * 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.

   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.

       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
   Extension: definition_lists
       Pandoc  supports  definition  lists,  using  the  syntax  of  PHP Markdown Extra with some
       extensions.

              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.

       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.
       The body of the definition (including the first line,  aside  from  the  colon  or  tilde)
       should  be  indented four spaces.  However, as with other Markdown lists, you can "lazily"
       omit indentation except at the beginning of a paragraph or other block element:

              Term 1

              :   Definition
              with lazy continuation.

                  Second paragraph of the definition.

       If you leave space before the definition (as in  the  example  above),  the  text  of  the
       definition will be treated as a paragraph.  In some output formats, this will mean greater
       spacing between term/definition pairs.  For a more compact definition list, omit the space
       before the definition:

              Term 1
                ~ Definition 1

              Term 2
                ~ Definition 2a
                ~ Definition 2b

       Note  that  space between items in a definition list is required.  (A variant that loosens
       this  requirement,  but  disallows  "lazy"  hard   wrapping,   can   be   activated   with
       compact_definition_lists: see Non-pandoc extensions, below.)

   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.

       Note: continuation paragraphs in example  lists  must  always  be  indented  four  spaces,
       regardless  of  the length of the list marker.  That is, example lists always behave as if
       the four_space_rule extension is set.  This is because example labels tend to be long, and
       indenting content to the first non-space character after the label would be awkward.

   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
       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
       A  line  containing  a row of three or more *, -, or _ characters (optionally separated by
       spaces) produces a horizontal rule:

              *  *  *  *

              ---------------

   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.

   Extension: table_captions
       A caption may optionally be provided with all 4 kinds of tables  (as  illustrated  in  the
       examples  below).   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.

   Extension: simple_tables
       Simple tables look like this:

                Right     Left     Center     Default
              -------     ------ ----------   -------
                   12     12        12            12

              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:

       · 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.

       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.

   Extension: multiline_tables
       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.

   Extension: grid_tables
       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.).  Cells that span multiple columns or rows are not
       supported.  Grid tables can be created easily using Emacs table mode.

       Alignments can be specified as with pipe tables, by putting colons at  the  boundaries  of
       the separator line after the header:

              +---------------+---------------+--------------------+
              | Right         | Left          | Centered           |
              +==============:+:==============+:==================:+
              | Bananas       | $1.34         | built-in wrapper   |
              +---------------+---------------+--------------------+

       For headerless tables, the colons go on the top line instead:

              +--------------:+:--------------+:------------------:+
              | Right         | Left          | Centered           |
              +---------------+---------------+--------------------+

   Grid Table Limitations
       Pandoc  does  not  support  grid  tables  with row spans or column spans.  This means that
       neither variable numbers of columns across  rows  nor  variable  numbers  of  rows  across
       columns  are supported by Pandoc.  All grid tables must have the same number of columns in
       each row, and the same number of rows in each column.  For example,  the  Docutils  sample
       grid tables will not render as expected with Pandoc.

   Extension: pipe_tables
       Pipe tables look like this:

              | Right | Left | Default | Center |
              |------:|:-----|---------|:------:|
              |   12  |  12  |    12   |    12  |
              |  123  |  123 |   123   |   123  |
              |    1  |    1 |     1   |     1  |

                : Demonstration of pipe table syntax.

       The  syntax  is  identical  to  PHP  Markdown Extra tables.  The beginning and ending pipe
       characters are optional, but pipes are required between all columns.  The colons  indicate
       column alignment as shown.  The header cannot be omitted.  To simulate a headerless table,
       include a header with blank cells.

       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.  If a pipe table contains a row  whose  printable  content  is
       wider  than  the  column  width (see --columns), then the table will take up the full text
       width and the cell contents will wrap, with the relative cell  widths  determined  by  the
       number  of  dashes  in  the  line  separating  the table header from the table body.  (For
       example ---|- would make the first column 3/4 and the second column 1/4 of the  full  text
       width.)  On  the  other  hand, if no lines are wider than column width, then cell contents
       will not be wrapped, and the cells will be sized to their contents.

       Note: pandoc also recognizes pipe tables of the following form,  as  can  be  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.

   Metadata blocks
   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.

   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.  (Note that, because of the way pandoc concatenates
       input files when several are provided, you may also keep the metadata in a  separate  YAML
       file and pass it to pandoc as an argument, along with your Markdown files:

              pandoc chap1.md chap2.md chap3.md metadata.yaml -s -o book.html

       Just be sure that the YAML file begins with --- and ends with --- or ....)

       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.

       When pandoc is used with -t markdown to create a Markdown document, a YAML metadata  block
       will  be  produced  only  if the -s/--standalone option is used.  All of the metadata will
       appear in a single block at the beginning of the document.

       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 or block-level formatting:

              ---
              title:  'This is the title: it contains a colon'
              author:
              - Author One
              - Author Two
              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>

       Variables  can  contain  arbitrary  YAML  structures,  but  the  template  must match this
       structure.  The author variable in the default templates expects a simple list or  string,
       but can be changed to support more complicated structures.  The following combination, for
       example, would add an affiliation to the author if one is given:

              ---
              title: The document title
              author:
              - name: Author One
                affiliation: University of Somewhere
              - name: Author Two
                affiliation: University of Nowhere
              ...

       To use the structured authors in the example above, you would need a custom template:

              $for(author)$
              $if(author.name)$
              $author.name$$if(author.affiliation)$ ($author.affiliation$)$endif$
              $else$
              $author$
              $endif$
              $endfor$

       Raw content to include in the document's header may be  specified  using  header-includes;
       however,  it  is  important  to  mark  up this content as raw code for a particular output
       format, using the raw_attribute extension), or it will be interpreted  as  markdown.   For
       example:

              header-includes:
              - |
                ```{=latex}
                \let\oldsection\section
                \renewcommand{\section}[1]{\clearpage\oldsection{#1}}
                ```

   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 \&#160; or \&nbsp;.

       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.

   Inline formatting
   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
   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
   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 P~a\ cat~, not P~a cat~.

   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:

              `<$>`{.haskell}

   Small caps
       To write small caps, use the smallcaps class:

              [Small caps]{.smallcaps}

       Or, without the bracketed_spans extension:

              <span class="smallcaps">Small caps</span>

       For compatibility with other Markdown flavors, CSS is also supported:

              <span style="font-variant:small-caps;">Small caps</span>

       This will work in all output formats that support small caps.

   Math
   Extension: tex_math_dollars
       Anything  between two $ characters will be treated as TeX math.  The opening $ must have a
       non-space character immediately to its right, while the closing $ must  have  a  non-space
       character immediately to its left, and must not be followed immediately by a digit.  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, Emacs Org mode, ConTeXt, ZimWiki
              It will appear verbatim between $ characters.

       reStructuredText
              It will be rendered using an interpreted text role :math:.

       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, DokuWiki
              It will be rendered inside <math> tags.

       Textile
              It will be rendered inside <span class="math"> tags.

       RTF, OpenDocument
              It will be rendered, if possible, using  Unicode  characters,  and  will  otherwise
              appear verbatim.

       ODT    It will be rendered, if possible, using MathML.

       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 CodeCogs 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.
              Therefore see Math rendering in HTML above.

   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, Emacs Org mode, 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.

   Extension: native_divs
       Use native pandoc Div blocks for content inside <div> tags.  For the most part this should
       give  the  same  output as markdown_in_html_blocks, but it makes it easier to write pandoc
       filters to manipulate groups of blocks.

   Extension: native_spans
       Use native pandoc Span blocks for content inside <span> tags.   For  the  most  part  this
       should give the same output as raw_html, but it makes it easier to write pandoc filters to
       manipulate groups of inlines.

   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, Emacs Org mode, and
       ConTeXt.

   Generic raw attribute
   Extension: raw_attribute
       Inline spans and fenced code blocks with a special kind of attribute will be parsed as raw
       content  with  the  designated format.  For example, the following produces a raw groff ms
       block:

              ```{=ms}
              .MYMACRO
              blah blah
              ```

       And the following produces a raw html inline element:

              This is `<a>html</a>`{=html}

       This can be useful to insert raw xml into docx documents, e.g.  a pagebreak:

              ```{=openxml}
              <w:p>
                <w:r>
                  <w:br w:type="page"/>
                </w:r>
              </w:p>
              ```

       The format name should match the target format name (see -t/--to, above, for  a  list,  or
       use  pandoc --list-output-formats).   Use  openxml  for  docx output, opendocument for odt
       output, html5 for epub3 output, html4 for epub2 output, and latex, beamer,  ms,  or  html5
       for pdf output (depending on what you use for --pdf-engine).

       This  extension  presupposes that the relevant kind of inline code or fenced code block is
       enabled.  Thus, for  example,  to  use  a  raw  attribute  with  a  backtick  code  block,
       backtick_code_blocks must be enabled.

       The raw attribute cannot be combined with regular attributes.

   LaTeX macros
   Extension: latex_macros
       For  output  formats other than LaTeX, pandoc will parse LaTeX macro definitions and apply
       the resulting macros to all LaTeX math and raw LaTeX.  So, for example, the following will
       work in all output formats, not just LaTeX:

              \newcommand{\tuple}[1]{\langle #1 \rangle}

              $\tuple{a, b, c}$

       Note that LaTeX macros will not be applied if they occur inside inside a raw span or block
       marked with the raw_attribute extension.

       When latex_macros is disabled, the raw LaTeX and math will not have macros applied.   This
       is usually a better approach when you are targeting LaTeX or PDF.

       Whether or not latex_macros is enabled, the macro definitions will still be passed through
       as raw LaTeX.

   Links
       Markdown allows links to be specified in several ways.

   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
       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.

       Email addresses in inline links are not autodetected, so they have  to  be  prefixed  with
       mailto:

              [Write me!](mailto:sam@green.eggs.ham)

   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  cannot  be  space  between  the two unless the spaced_reference_links extension is
       enabled.) 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.  The label must not be parseable as a citation (assuming the  citations
       extension is enabled): citations take precedence over link labels.

       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:

              See [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

   Extension: shortcut_reference_links
       In a shortcut reference link, the second pair of brackets may be omitted entirely:

              See [my website].

              [my website]: http://foo.bar.baz

   Internal links
       To link to  another  section  of  the  same  document,  use  the  automatically  generated
       identifier (see Header identifiers).  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
       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

   Extension: implicit_figures
       An image with nonempty alt text, occurring by itself in a paragraph, will be rendered as a
       figure with a caption.  The image's alt text will be used as the caption.

              ![This is the caption](/url/of/image.png)

       How this is rendered depends on the output format.  Some output formats (e.g.  RTF) do not
       yet support figures.  In those formats, you'll just get an image in a paragraph by itself,
       with no caption.

       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)\

       Note that in reveal.js slide shows, an image in a paragraph by itself that has the stretch
       class will fill the screen, and the caption and figure tags will be omitted.

   Extension: link_attributes
       Attributes can be set on links and images:

              An inline ![image](foo.jpg){#id .class width=30 height=20px}
              and a reference ![image][ref] with attributes.

              [ref]: foo.jpg "optional title" {#id .class key=val key2="val 2"}

       (This syntax is compatible with PHP Markdown Extra when only #id and .class are used.)

       For HTML and EPUB, all attributes except width and height (but including srcset and sizes)
       are  passed  through as is.  The other writers ignore attributes that are not supported by
       their output format.

       The width and height attributes on images are treated  specially.   When  used  without  a
       unit,  the  unit  is assumed to be pixels.  However, any of the following unit identifiers
       can be used: px, cm, mm, in, inch and %.  There must not be any spaces between the  number
       and the unit.  For example:

              ![](file.jpg){ width=50% }

       · Dimensions  are  converted  to  inches  for  output  in  page-based  formats like LaTeX.
         Dimensions are converted to pixels for output  in  HTML-like  formats.   Use  the  --dpi
         option to specify the number of pixels per inch.  The default is 96dpi.

       · The % unit is generally relative to some available space.  For example the above example
         will      render      to       <img href="file.jpg" style="width: 50%;" />       (HTML),
         \includegraphics[width=0.5\textwidth]{file.jpg}                (LaTeX),               or
         \externalfigure[file.jpg][width=0.5\textwidth] (ConTeXt).

       · Some output formats have a notion of a class (ConTeXt) or  a  unique  identifier  (LaTeX
         \caption), or both (HTML).

       · When  no  width or height attributes are specified, the fallback is to look at the image
         resolution and the dpi metadata embedded in the image file.

   Divs and Spans
       Using the native_divs and native_spans extensions (see above), HTML syntax can be used  as
       part  of  markdown to create native Div and Span elements in the pandoc AST (as opposed to
       raw HTML).  However, there is also nicer syntax available:

   Extension: fenced_divs
       Allow special fenced syntax for native Div blocks.  A Div starts with a  fence  containing
       at  least three consecutive colons plus some attributes.  The attributes may optionally be
       followed by another string of consecutive colons.  The attribute syntax is exactly  as  in
       fenced  code  blocks (see Extension: fenced_code_attributes).  As with fenced code blocks,
       one can use either attributes in curly braces or a single unbraced  word,  which  will  be
       treated  as  a class name.  The Div ends with another line containing a string of at least
       three consecutive colons.  The  fenced  Div  should  be  separated  by  blank  lines  from
       preceding and following blocks.

       Example:

              ::::: {#special .sidebar}
              Here is a paragraph.

              And another.
              :::::

       Fenced  divs  can  be  nested.   Opening  fences  are distinguished because they must have
       attributes:

              ::: Warning ::::::
              This is a warning.

              ::: Danger
              This is a warning within a warning.
              :::
              ::::::::::::::::::

       Fences without attributes are always closing fences.  Unlike with fenced code blocks,  the
       number  of  colons  in  the  closing fence need not match the number in the opening fence.
       However, it can be helpful for visual clarity  to  use  fences  of  different  lengths  to
       distinguish nested divs from their parents.

   Extension: bracketed_spans
       A  bracketed  sequence  of inlines, as one would use to begin a link, will be treated as a
       Span with attributes if it is followed immediately by attributes:

              [This is *some text*]{.class key="val"}

   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.).  Each
       footnote should be separated from surrounding content (including other footnotes) by blank
       lines.

   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
   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,  or  --bibliography  command  line
       argument.   You  can supply multiple --bibliography arguments or set bibliography metadata
       field to YAML array, if you want to use multiple bibliography files.  The bibliography may
       have any of these formats:

       Format        File extension
       ─────────────────────────────
       BibLaTeX      .bib
       BibTeX        .bibtex
       Copac         .copac
       CSL JSON      .json
       CSL YAML      .yaml
       EndNote       .enl
       EndNote XML   .xml
       ISI           .wos
       MEDLINE       .medline
       MODS          .mods
       RIS           .ris

       Note  that  .bib  can  be  used  with both BibTeX and BibLaTeX files; use .bibtex to force
       BibTeX.

       Note that pandoc-citeproc --bib2json and pandoc-citeproc --bib2yaml can produce .json  and
       .yaml files from any of the supported formats.

       In-field  markup:  In  BibTeX  and  BibLaTeX databases, pandoc-citeproc parses a subset of
       LaTeX markup; in CSL YAML databases, pandoc  Markdown;  and  in  CSL  JSON  databases,  an
       HTML-like markup:

       <i>...</i>
              italics

       <b>...</b>
              bold

       <span style="font-variant:small-caps;">...</span> or <sc>...</sc>
              small capitals

       <sub>...</sub>
              subscript

       <sup>...</sup>
              superscript

       <span class="nocase">...</span>
              prevent a phrase from being capitalized as title case

       pandoc-citeproc -j  and  -y  interconvert  the  CSL  JSON  and  CSL YAML formats as far as
       possible.

       As an alternative to specifying a bibliography  file  using  --bibliography  or  the  YAML
       metadata  field bibliography, you can include the citation data directly in the references
       field of the document's YAML metadata.  The field should contain an array of  YAML-encoded
       references, for example:

              ---
              references:
              - type: article-journal
                id: WatsonCrick1953

                  given: J. D.
                - family: Crick
                  given: F. H. C.
                issued:

              ...

       (pandoc-citeproc --bib2yaml  can  produce  these  from  a  bibliography file in one of the
       supported formats.)

       Citations and references can be formatted using any style supported by the Citation  Style
       Language,  listed  in  the  Zotero  Style Repository.  These files are specified using the
       --csl option or the csl metadata field.  By default, pandoc-citeproc will use the  Chicago
       Manual  of  Style  author-date  format.   The  CSL project provides further information on
       finding and editing styles.

       To  make  your  citations  hyperlinks  to  the  corresponding  bibliography  entries,  add
       link-citations: true to your YAML metadata.

       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, digit, or _, and may contain alphanumerics, _, and internal punctuation characters
       (:.#$%&-+?<>~/).  Here are some examples:

              Blah blah [see @doe99, pp. 33-35; also @smith04, chap. 1].

              Blah blah [@doe99, pp. 33-35, 38-39 and *passim*].

              Blah blah [@smith04; @doe99].

       pandoc-citeproc  detects  locator  terms  in  the CSL locale files.  Either abbreviated or
       unabbreviated forms are accepted.  In the en-US locale, locator terms can  be  written  in
       either  singular  or  plural  forms,  as  book,  bk./bks.;  chapter, chap./chaps.; column,
       col./cols.; figure, fig./figs.; folio, fol./fols.; number, no./nos.; line,  l./ll.;  note,
       n./nn.;  opus,  op./opp.;  page, p./pp.; paragraph, para./paras.; part, pt./pts.; section,
       sec./secs.; sub verbo, s.v./s.vv.; verse, v./vv.; volume, vol./vols.; ¶/¶¶; §/§§.   If  no
       locator term is used, "page" is assumed.

       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.

       It is possible to create a bibliography with all the citations, whether or not they appear
       in the document, by using a wildcard:

              ---
              nocite: |
                @*
              ...

       For  LaTeX  or PDF output, you can also use natbib or biblatex to render bibliography.  In
       order to do so, specify  bibliography  files  as  outlined  above,  and  add  --natbib  or
       --biblatex argument to pandoc invocation.  Bear in mind that bibliography files have to be
       in respective format (either BibTeX or BibLaTeX).

       For more information, see the pandoc-citeproc man page.

   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: 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 only has an effect if smart is enabled.  It is
       selected automatically for textile input.

   Extension: angle_brackets_escapable
       Allow  < and > to be backslash-escaped, as they can be in GitHub flavored Markdown but not
       original Markdown.  This is implied by pandoc's default all_symbols_escapable.

   Extension: lists_without_preceding_blankline
       Allow a list to occur right after a paragraph, with no intervening blank space.

   Extension: four_space_rule
       Selects the pandoc <= 2.0 behavior for parsing lists,  so  that  four  spaces  indent  are
       needed for list item continuation paragraphs.

   Extension: spaced_reference_links
       Allow whitespace between the two components of a reference link, for example,

              [foo] [bar].

   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: east_asian_line_breaks
       Causes newlines within a paragraph to be ignored, rather than being treated as  spaces  or
       as  hard  line  breaks, when they occur between two East Asian wide characters.  This is a
       better choice than ignore_line_breaks for texts that include a  mix  of  East  Asian  wide
       characters and other characters.

   Extension: emoji
       Parses textual emojis like :smile: as Unicode emoticons.

   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]: Hypertext 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: mmd_link_attributes
       Parses  multimarkdown  style  key-value  attributes  on  link  and image references.  This
       extension should not be confused with the link_attributes extension.

              This is a reference ![image][ref] with multimarkdown attributes.

              [ref]: http://path.to/image "Image title" width=20px height=30px
                     id=myId class="myClass1 myClass2"

   Extension: mmd_header_identifiers
       Parses multimarkdown style header identifiers (in square brackets, after  the  header  but
       before any trailing #s in an ATX header).

   Extension: compact_definition_lists
       Activates  the  definition  list syntax of pandoc 1.12.x and earlier.  This syntax differs
       from the one described above under Definition lists in several respects:

       · No blank line is required between consecutive items of the definition list.

       · To get a "tight" or "compact" list, omit space  between  consecutive  items;  the  space
         between a term and its definition does not affect anything.

       · Lazy  wrapping of paragraphs is not allowed: the entire definition must be indented four
         spaces.

   Markdown variants
       In addition to pandoc's extended Markdown, the following Markdown variants are supported:

       markdown_phpextra (PHP Markdown Extra)
              footnotes,   pipe_tables,   raw_html,    markdown_attribute,    fenced_code_blocks,
              definition_lists,    intraword_underscores,   header_attributes,   link_attributes,
              abbreviations, shortcut_reference_links, spaced_reference_links.

       markdown_github (deprecated GitHub-Flavored Markdown)
              pipe_tables, raw_html, fenced_code_blocks, gfm_auto_identifiers, ascii_identifiers,
              backtick_code_blocks,            autolink_bare_uris,           space_in_atx_header,
              intraword_underscores,      strikeout,       emoji,       shortcut_reference_links,
              angle_brackets_escapable, lists_without_preceding_blankline.

       markdown_mmd (MultiMarkdown)
              pipe_tables,        raw_html,        markdown_attribute,       mmd_link_attributes,
              tex_math_double_backslash,   intraword_underscores,   mmd_title_block,   footnotes,
              definition_lists,         all_symbols_escapable,        implicit_header_references,
              auto_identifiers,         mmd_header_identifiers,         shortcut_reference_links,
              implicit_figures,        superscript,        subscript,       backtick_code_blocks,
              spaced_reference_links, raw_attribute.

       markdown_strict (Markdown.pl)
              raw_html, shortcut_reference_links, spaced_reference_links.

       We also support commonmark and gfm (GitHub-Flavored Markdown, which is  implemented  as  a
       set of extensions on commonmark).

       Note,  however,  that  commonmark and gfm have limited support for extensions.  Only those
       listed below (and smart and raw_tex) will work.   The  extensions  can,  however,  all  be
       individually disabled.  Also, raw_tex only affects gfm output, not input.

       gfm (GitHub-Flavored Markdown)
              pipe_tables,  raw_html,  fenced_code_blocks,  auto_identifiers,  ascii_identifiers,
              backtick_code_blocks,   autolink_bare_uris,    intraword_underscores,    strikeout,
              hard_line_breaks, emoji, shortcut_reference_links, angle_brackets_escapable.

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, or slides shows
       in Microsoft PowerPoint format.

       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 JavaScript 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
       Variables  for slides, 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.

       To produce a Powerpoint slide show, type

              pandoc habits.txt -o habits.pptx

   Structuring the slide show
       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.

       · Content above the slide level will not appear in the slide show.

       · 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
       By default, these writers produce 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, put it in a div block with  class  incremental
       or  nonincremental.   So, for example, using the fenced div syntax, the following would be
       incremental regardless of the document default:

              ::: incremental

              - Eat spaghetti
              - Drink wine

              :::

       or

              ::: nonincremental

              - Eat spaghetti
              - Drink wine

              :::

       While using incremental and nonincremental divs are  the  recommended  method  of  setting
       incremental  lists  on  a per-case basis, an older method is also supported: putting lists
       inside a blockquote will depart from the  document  default  (that  is,  it  will  display
       incrementally without the -i option and all at once with the -i option):

              > - Eat spaghetti
              > - Drink wine

       Both methods allow incremental and nonincremental lists to be mixed in a single document.

   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
       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.

       All reveal.js configuration options can be set through variables.  For example, themes can
       be used by setting the theme variable:

              -V theme=moon

       Or you can specify a custom stylesheet using the --css option.

       To style beamer slides, you can specify a theme, colortheme,  fonttheme,  innertheme,  and
       outertheme, 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 are supported in reveal.js and PowerPoint (pptx) output.  You can add notes
       to your Markdown document thus:

              ::: notes

              This is my note.

              - It can contain Markdown
              - like this list

              :::

       To show the notes window in reveal.js, press s while viewing  the  presentation.   Speaker
       notes in PowerPoint will be available, as usual, in handouts and presenter view.

       Notes  are not yet supported for other slide formats, but the notes will not appear on the
       slides themselves.

   Columns
       To put material in side by side columns, you can use a native  div  container  with  class
       columns, containing two or more div containers with class column and a width attribute:

              :::::::::::::: {.columns}
              ::: {.column width="40%"}
              contents...
              :::
              ::: {.column width="60%"}
              contents...
              :::
              ::::::::::::::

   Frame attributes in beamer
       Sometimes  it  is  necessary  to  add the LaTeX [fragile] option to a frame in beamer (for
       example, when using the minted environment).  This can be forced  by  adding  the  fragile
       class to the header introducing the slide:

              # Fragile slide {.fragile}

       All  of the other frame attributes described in Section 8.1 of the Beamer User's Guide may
       also be used: allowdisplaybreaks, allowframebreaks, b, c, t,  environment,  label,  plain,
       shrink.

   Background in reveal.js
       Background images can be added to self-contained reveal.js slideshows.

       For   the   same   image   on   every   slide,  use  the  reveal.js  configuration  option
       parallaxBackgroundImage either in the YAML metadata block or as a  command-line  variable.
       You  can also set parallaxBackgroundHorizontal and parallaxBackgroundVertical the same way
       and must also set parallaxBackgroundSize to have your values take effect.

       To set an image for a particular slide,  add  {data-background-image="/path/to/image"}  to
       the first slide-level header on the slide (which may even be empty).

       In  reveal.js's  overview mode, the parallaxBackgroundImage will show up only on the first
       slide.

       Other background settings also work on individual slides, including  data-background-size,
       data-background-repeat, data-background-color, data-transition, and data-transition-speed.

       See the reveal.js documentation for more details.

       For example:

              ---
              title: My Slideshow
              parallaxBackgroundImage: /path/to/my/background_image.png
              ---

              ## Slide One

              Slide 1 has background_image.png as its background.

              ## {data-background-image="/path/to/special_image.jpg"}

              Slide 2 has a special image for its background, even though the header has no content.

CREATING EPUBS WITH PANDOC

   EPUB Metadata
       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
              publisher:  My Press

              ibooks:
                version: 1.3.4
              ...

       The following fields are recognized:

       identifier
              Either a string value or an object with fields text and scheme.  Valid  values  for
              scheme   are   ISBN-10,   GTIN-13,  UPC,  ISMN-10,  DOI,  LCCN,  GTIN-14,  ISBN-13,
              Legal deposit number, URN, OCLC, ISMN-13, ISBN-A, JP, OLCC.

       title  Either a string value, or an object with fields file-as and type, or a list of such
              objects.   Valid  values  for  type are main, subtitle, short, collection, edition,
              extended.

       creator
              Either a string value, or an object with fields role, file-as, and text, or a  list
              of  such objects.  Valid values for role are MARC relators, but pandoc will attempt
              to translate the human-readable  versions  (like  "author"  and  "editor")  to  the
              appropriate marc relators.

       contributor
              Same format as creator.

       date   A  string  value  in  YYYY-MM-DD format.  (Only the year is necessary.) Pandoc will
              attempt to convert other common date formats.

       lang (or legacy: language)
              A string value in BCP 47 format.  Pandoc will default  to  the  local  language  if
              nothing is specified.

              Either  ltr  or  rtl.   Specifies  the page-progression-direction attribute for the
              spine element.

       ibooks iBooks-specific metadata, with the following fields:

              · version: (string)

              · specified-fonts: true|false (default false)

              · ipad-orientation-lock: portrait-only|landscape-only

              · iphone-orientation-lock: portrait-only|landscape-only

              · binding: true|false (default true)

              · scroll-axis: vertical|horizontal|default

   Linked media
       By default, pandoc will download linked media (including audio and video) and  include  it
       in  the EPUB container, yielding a completely self-contained EPUB.  If you want to link to
       external media resources instead, use raw HTML in your source and add data-external="1" to
       the tag with the src attribute.  For example:

              <audio controls="1">
                <source src="http://example.com/music/toccata.mp3"
                        data-external="1" type="audio/mpeg">
                </source>
              </audio>

SYNTAX HIGHLIGHTING

       Pandoc  will  automatically  highlight syntax in fenced code blocks that are marked with a
       language name.  The Haskell library skylighting is used for highlighting, which  works  in
       HTML,  Docx,  Ms,  and LaTeX/PDF output.  To see a list of language names that pandoc will
       recognize, type pandoc --list-highlight-languages.

       The color scheme can be selected using the --highlight-style option.   The  default  color
       scheme  is  pygments,  which  imitates the default color scheme used by the Python library
       pygments (though pygments is not actually used to do the highlighting).  To see a list  of
       highlight styles, type pandoc --list-highlight-styles.

       To disable highlighting, use the --no-highlight option.

CUSTOM STYLES IN DOCX

   Input
       The  docx  reader,  by  default,  only  reads those styles that it can convert into pandoc
       elements, either by  direct  conversion  or  interpreting  the  derivation  of  the  input
       document's styles.

       By  enabling  the  styles  extension  in the docx reader (-f docx+styles), you can produce
       output that maintains the styles of the input  document,  using  the  custom-style  class.
       Paragraph styles are interpreted as divs, while character styles are interpreted as spans.

       For example, using the custom-style-reference.docx file in the test directory, we have the
       following different outputs:

       Without the +styles extension:

              $ pandoc test/docx/custom-style-reference.docx -f docx -t markdown
              This is some text.

              This is text with an *emphasized* text style. And this is text with a
              **strengthened** text style.

              > Here is a styled paragraph that inherits from Block Text.

       And with the extension:

              $ pandoc test/docx/custom-style-reference.docx -f docx+styles -t markdown

              ::: {custom-style="FirstParagraph"}
              This is some text.
              :::

              ::: {custom-style="BodyText"}
              This is text with an [emphasized]{custom-style="Emphatic"} text style.
              And this is text with a [strengthened]{custom-style="Strengthened"}
              text style.
              :::

              ::: {custom-style="MyBlockStyle"}
              > Here is a styled paragraph that inherits from Block Text.
              :::

       With these custom styles, you can  use  your  input  document  as  a  reference-doc  while
       creating  docx  output  (see below), and maintain the same styles in your input and output
       files.

   Output
       By default, pandoc's docx output applies a predefined set of styles  for  blocks  such  as
       paragraphs  and  block  quotes,  and  uses  largely default formatting (italics, bold) for
       inlines.  This will work for most purposes, especially alongside  a  reference.docx  file.
       However,  if  you  need  to apply your own styles to blocks, or match a preexisting set of
       styles, pandoc allows you to define custom styles for  blocks  and  text  using  divs  and
       spans, respectively.

       If  you  define  a  div  or  span  with the attribute custom-style, pandoc will apply your
       specified style to the contained elements.  So,  for  example  using  the  bracketed_spans
       syntax,

              [Get out]{custom-style="Emphatically"}, he said.

       would  produce  a  docx  file  with  "Get  out"  styled with character style Emphatically.
       Similarly, using the fenced_divs syntax,

              Dickinson starts the poem simply:

              ::: {custom-style="Poetry"}
              | A Bird came down the Walk---
              | He did not know I saw---
              :::

       would style the two contained lines with the Poetry paragraph style.

       If the styles are not yet in your reference.docx, they will be defined in the output  file
       as  inheriting  from  normal text.  If they are already defined, pandoc will not alter the
       definition.

       This feature allows for greatest customization in conjunction with pandoc filters.  If you
       want all paragraphs after block quotes to be indented, you can write a filter to apply the
       styles necessary.  If you want all italics to be transformed  to  the  Emphasis  character
       style  (perhaps  to  change  their color), you can write a filter which will transform all
       italicized inlines to inlines within an Emphasis custom-style span.

CUSTOM WRITERS

       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
