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.  It can read Markdown, CommonMark, PHP Markdown Extra, GitHub-Flavored  Markdown,
       MultiMarkdown,  and  (subsets of) Textile, reStructuredText, HTML, LaTeX, MediaWiki markup, TWiki markup,
       Haddock markup, OPML, Emacs Org mode, DocBook, txt2tags, EPUB, ODT and Word docx; and it can write  plain
       text,    Markdown,   CommonMark,   PHP   Markdown   Extra,   GitHub-Flavored   Markdown,   MultiMarkdown,
       reStructuredText, XHTML, HTML5, LaTeX (including  beamer  slide  shows),  ConTeXt,  RTF,  OPML,  DocBook,
       OpenDocument,  ODT,  Word  docx,  GNU Texinfo, MediaWiki markup, DokuWiki markup, ZimWiki markup, Haddock
       markup, EPUB (v2 or v3), FictionBook2, Textile, groff man pages, Emacs Org mode, AsciiDoc, InDesign ICML,
       TEI  Simple,  and  Slidy,  Slideous, DZSlides, reveal.js or S5 HTML slide shows.  It can also produce PDF
       output on systems where LaTeX, ConTeXt, or wkhtmltopdf is installed.

       Pandoc's enhanced version of Markdown includes syntax for  footnotes,  tables,  flexible  ordered  lists,
       definition  lists, fenced code blocks, superscripts and subscripts, strikeout, metadata blocks, automatic
       tables of contents, embedded LaTeX math, citations, and Markdown  inside  HTML  block  elements.   (These
       enhancements,  described further under Pandoc's Markdown, can be disabled using the markdown_strict input
       or output format.)

       In contrast to most existing tools for converting Markdown to HTML, which use regex substitutions, pandoc
       has  a  modular design: it consists of a set of readers, which parse text in a given format and produce a
       native representation of the document, and a set of writers, which  convert  this  native  representation
       into a target format.  Thus, adding an input or output format requires only adding a reader or writer.

       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-file is specified, input is read from stdin.  Otherwise,  the  input-files  are  concatenated
       (with  a  blank line between each) and used as input.  Output goes to stdout by default (though output to
       stdout is disabled for the odt, docx, epub, and epub3 output formats).  For output to a file, use the  -o
       option:

              pandoc -o output.html input.txt

       By  default,  pandoc  produces  a  document  fragment, not a standalone document with a proper header and
       footer.  To produce a standalone document, 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.

       Instead of a file, an absolute URI may be given.  In this case pandoc will fetch the content using HTTP:

              pandoc -f html -t markdown http://www.fsf.org

       If multiple input files are given, pandoc will concatenate them  all  (with  blank  lines  between  them)
       before parsing.  This feature is disabled for binary input formats such as EPUB, odt, and docx.

       The  format  of  the  input and output can be specified explicitly using command-line options.  The input
       format can be specified using the -r/--read or -f/--from options, the output format using the  -w/--write
       or -t/--to options.  Thus, to convert hello.txt from Markdown to LaTeX, you could type:

              pandoc -f markdown -t latex hello.txt

       To convert hello.html from HTML to Markdown:

              pandoc -f html -t markdown hello.html

       Supported  output  formats are listed below under the -t/--to option.  Supported input formats are listed
       below under the -f/--from option.  Note that the rst, textile, latex, and html readers are not  complete;
       there are some constructs that they do not parse.

       If  the  input  or  output  format  is not specified explicitly, pandoc will attempt to guess it from the
       extensions of the input and output filenames.  Thus, for example,

              pandoc -o hello.tex hello.txt

       will convert hello.txt from Markdown to LaTeX.  If no output file is specified (so that  output  goes  to
       stdout),  or  if  the  output file's extension is unknown, the output format will default to HTML.  If no
       input file is specified (so that input comes from stdin), or if the input files' extensions are  unknown,
       the input format will be assumed to be Markdown unless explicitly specified.

       Pandoc  uses the UTF-8 character encoding for both input and output.  If your local character encoding is
       not UTF-8, you should pipe input and output through iconv:

              iconv -t utf-8 input.txt | pandoc | iconv -f utf-8

       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.  By default, pandoc  will  use  LaTeX  to
       convert it to PDF:

              pandoc test.txt -o test.pdf

       Production  of  a  PDF requires that a LaTeX engine be installed (see --latex-engine, below), and assumes
       that the following LaTeX packages are available:  amsfonts,  amsmath,  lm,  ifxetex,  ifluatex,  eurosym,
       listings  (if the --listings option is used), fancyvrb, longtable, booktabs, graphicx and grffile (if the
       document contains images), hyperref, 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 mathspec, polyglossia (with lang), xecjk, and bidi (with the  dir  variable  set).
       The upquote and microtype packages are used if available, and csquotes will be used for smart punctuation
       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.  These are included with all recent versions of
       TeX Live.

       Alternatively, pandoc can use ConTeXt or wkhtmltopdf to create a PDF.  To do this, specify an output file
       with a .pdf extension, as before, but add -t context or -t html5 to the command line.

       PDF  output  can be controlled using variables for LaTeX (if LaTeX is used) and variables for ConTeXt (if
       ConTeXt is used).  If wkhtmltopdf is used, then  the  variables  margin-left,  margin-right,  margin-top,
       margin-bottom, and papersize will affect the output, as will --css.

OPTIONS

   General options
       -f FORMAT, -r FORMAT, --from=FORMAT, --read=FORMAT
              Specify  input  format.  FORMAT can be native (native Haskell), json (JSON version of native AST),
              markdown  (pandoc's  extended   Markdown),   markdown_strict   (original   unextended   Markdown),
              markdown_phpextra  (PHP  Markdown Extra), markdown_github (GitHub-Flavored Markdown), markdown_mmd
              (MultiMarkdown), commonmark (CommonMark Markdown), textile (Textile), rst (reStructuredText), html
              (HTML),  docbook  (DocBook), t2t (txt2tags), docx (docx), odt (ODT), epub (EPUB), opml (OPML), org
              (Emacs Org mode), mediawiki (MediaWiki markup), twiki (TWiki markup), haddock (Haddock markup), or
              latex (LaTeX).  If +lhs is appended to markdown, rst, latex, or html, the input will be treated as
              literate Haskell source: see Literate Haskell support, below.  Markdown syntax extensions  can  be
              individually  enabled  or  disabled by appending +EXTENSION or -EXTENSION to the format name.  So,
              for example, markdown_strict+footnotes+definition_lists is  strict  Markdown  with  footnotes  and
              definition  lists  enabled, and markdown-pipe_tables+hard_line_breaks is pandoc's Markdown without
              pipe tables and with hard line breaks.  See Pandoc's Markdown, below, for a list of extensions and
              their names.  See --list-input-formats and --list-extensions, below.

       -t FORMAT, -w FORMAT, --to=FORMAT, --write=FORMAT
              Specify  output format.  FORMAT can be native (native Haskell), json (JSON version of native AST),
              plain (plain text), markdown (pandoc's extended Markdown),  markdown_strict  (original  unextended
              Markdown),  markdown_phpextra  (PHP  Markdown  Extra), markdown_github (GitHub-Flavored Markdown),
              markdown_mmd (MultiMarkdown),  commonmark  (CommonMark  Markdown),  rst  (reStructuredText),  html
              (XHTML),  html5  (HTML5),  latex (LaTeX), beamer (LaTeX beamer slide show), context (ConTeXt), man
              (groff man), mediawiki (MediaWiki markup), dokuwiki (DokuWiki markup), zimwiki  (ZimWiki  markup),
              textile  (Textile), org (Emacs Org mode), texinfo (GNU Texinfo), opml (OPML), docbook (DocBook 4),
              docbook5 (DocBook 5), opendocument (OpenDocument), odt  (OpenOffice  text  document),  docx  (Word
              docx), haddock (Haddock markup), rtf (rich text format), epub (EPUB v2 book), epub3 (EPUB v3), fb2
              (FictionBook2 e-book), asciidoc (AsciiDoc), icml (InDesign ICML), tei (TEI Simple),  slidy  (Slidy
              HTML  and  JavaScript  slide  show),  slideous (Slideous HTML and JavaScript slide show), dzslides
              (DZSlides HTML5 + JavaScript slide show), revealjs (reveal.js HTML5 + JavaScript slide  show),  s5
              (S5  HTML  and  JavaScript  slide  show),  or the path of a custom lua writer (see Custom writers,
              below).  Note that odt, epub, and epub3 output will not be directed to stdout; an output  filename
              must  be  specified  using  the  -o/--output option.  If +lhs is appended to markdown, rst, latex,
              beamer, html, or html5, the output will be rendered  as  literate  Haskell  source:  see  Literate
              Haskell  support,  below.   Markdown  syntax extensions can be individually enabled or disabled by
              appending +EXTENSION or -EXTENSION  to  the  format  name,  as  described  above  under  -f.   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.  (Exception: if
              the output format is odt, docx, epub, or epub3, output to stdout is disabled.)

       --data-dir=DIRECTORY
              Specify the user data directory to search for pandoc data files.  If this option is not specified,
              the default user data directory will be used.  This is, 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.

       --list-input-formats
              List supported input formats, one per line.

       --list-output-formats
              List supported output formats, one per line.

       --list-extensions
              List supported Markdown extensions, one per line, followed by a + or - indicating  whether  it  is
              enabled by default in pandoc's Markdown.

       --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
       -R, --parse-raw
              Parse  untranslatable  HTML codes and LaTeX environments as raw HTML or LaTeX, instead of ignoring
              them.  Affects only HTML and LaTeX input.  Raw HTML can be printed in Markdown,  reStructuredText,
              Emacs  Org  mode,  HTML,  Slidy,  Slideous,  DZSlides,  reveal.js, and S5 output; raw LaTeX can be
              printed in Markdown, reStructuredText, Emacs Org mode, LaTeX, and ConTeXt output.  The default  is
              for  the readers to omit untranslatable HTML codes and LaTeX environments.  (The LaTeX reader does
              pass through untranslatable LaTeX commands, even if -R is not specified.)

       -S, --smart
              Produce typographically correct output,  converting  straight  quotes  to  curly  quotes,  ---  to
              em-dashes,  --  to  en-dashes, and ... to ellipses.  Nonbreaking spaces are inserted after certain
              abbreviations, such as “Mr.” (Note: This option is selected automatically when the  output  format
              is latex or context, unless --no-tex-ligatures is used.  It has no effect for latex input.)

       --old-dashes
              Selects the pandoc <= 1.8.2.1 behavior for parsing smart dashes: - before a numeral is an en-dash,
              and -- is an em-dash.  This option is selected automatically for textile input.

       --base-header-level=NUMBER
              Specify the base level for headers (defaults to 1).

       --indented-code-classes=CLASSES
              Specify classes to  use  for  indented  code  blocks–for  example,  perl,numberLines  or  haskell.
              Multiple classes may be separated by spaces or commas.

       --default-image-extension=EXTENSION
              Specify  a  default  extension to use when image paths/URLs have no extension.  This allows you to
              use the same source for formats that require different kinds of  images.   Currently  this  option
              only affects the Markdown and LaTeX readers.

       --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)

              3. $PATH (executable only)

       -M KEY[=VAL], --metadata=KEY[:VAL]
              Set the metadata field KEY to the value VAL.  A value specified on the command  line  overrides  a
              value  specified  in the document.  Values will be parsed as YAML boolean or string values.  If no
              value is specified, the value will be treated as Boolean true.  Like --variable, --metadata causes
              template  variables  to  be  set.   But  unlike --variable, --metadata affects the metadata of the
              underlying document (which is accessible from filters and may be printed in some output formats).

       --normalize
              Normalize the document after reading: merge adjacent Str or Emph elements, for example, and remove
              repeated Spaces.

       -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.  This option only affects the docx reader.

       --extract-media=DIR
              Extract images and other media contained in a docx or epub container to the path DIR, creating  it
              if  necessary,  and  adjust  the  images references in the document so they point to the extracted
              files.  This option only affects the docx and epub readers.

   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.

       --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.

       --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.

       --no-wrap
              Deprecated synonym for --wrap=none.

       --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, and
              rst, an instruction to create one) in the output document.  This option  has  no  effect  on  man,
              docbook, docbook5, slidy, slideous, s5, or odt output.

       --toc-depth=NUMBER
              Specify the number of section levels to include in the table of contents.  The default is 3 (which
              means that level 1, 2, and 3 headers will be listed in the contents).

       --no-highlight
              Disables syntax highlighting for code blocks and inlines, even when a language attribute is given.

       --highlight-style=STYLE
              Specifies the coloring style to be used in highlighted source code.   Options  are  pygments  (the
              default),  kate,  monochrome,  breezeDark,  espresso,  zenburn,  haddock,  and  tango.   For  more
              information  on  syntax  highlighting  in  pandoc,  see  Syntax  highlighting,  below.   See  also
              --list-highlight-styles.

       -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.

   Options affecting specific writers
       --self-contained
              Produce  a standalone HTML file with no external dependencies, using data: URIs to incorporate the
              contents of linked scripts, stylesheets,  images,  and  videos.   The  resulting  file  should  be
              “self-contained,”  in  the sense that it needs no external files and no net access to be displayed
              properly by a browser.  This option works only with HTML output formats,  including  html,  html5,
              html+lhs,   html5+lhs,  s5,  slidy,  slideous,  dzslides,  and  revealjs.   Scripts,  images,  and
              stylesheets at absolute URLs will be downloaded; those at relative URLs will be sought 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).   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  only for HTML output (which uses
              numerical entities instead of UTF-8 when this option is selected).

       --reference-links
              Use reference-style links, rather than inline links, in writing Markdown or reStructuredText.   By
              default   inline   links  are  used.   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.

       --chapters
              Deprecated synonym for --top-level-division=chapter.

       --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.

       --no-tex-ligatures
              Do not use the TeX ligatures for quotation marks, apostrophes, and dashes (`...', ``..'', --, ---)
              when writing or reading LaTeX or ConTeXt.  In reading LaTeX, parse the  characters  `,  ',  and  -
              literally,  rather  than  parsing  ligatures  for quotation marks and dashes.  In writing LaTeX or
              ConTeXt, print unicode quotation mark and dash characters literally, rather than  converting  them
              to  the  standard ASCII TeX ligatures.  Note: normally --smart is selected automatically for LaTeX
              and ConTeXt output, but it must be specified explicitly if --no-tex-ligatures is selected.  If you
              use  literal  curly  quotes,  dashes,  and  ellipses  in  your  source,  then  you may want to use
              --no-tex-ligatures without --smart.

       --listings
              Use 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.  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 <div> tags (or <section> tags in HTML5), and attach identifiers to the  enclosing
              <div> (or <section>) 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 automatically generated identifiers in HTML and DocBook
              output, and to footnote numbers in Markdown output.   This  is  useful  for  preventing  duplicate
              identifiers when generating fragments to be included in other pages.

       -T STRING, --title-prefix=STRING
              Specify  STRING as a prefix at the beginning of the title that appears in the HTML header (but not
              in the title as it appears at the beginning of the HTML body).  Implies --standalone.

       -c URL, --css=URL
              Link to a CSS style sheet.  This option can be used repeatedly to include  multiple  files.   They
              will be included in the order specified.

       --reference-odt=FILE
              Use  the specified file as a style reference in producing an ODT.  For best results, the reference
              ODT should be a modified version of an ODT produced using pandoc.  The contents of  the  reference
              ODT are ignored, but its stylesheets are used in the new ODT.  If no reference ODT is specified on
              the command line, pandoc will look for a file  reference.odt  in  the  user  data  directory  (see
              --data-dir).  If this is not found either, sensible defaults will be used.

              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.docx in LibreOffice, modify the styles as you wish, and save the file.

       --reference-docx=FILE
              Use  the  specified  file  as  a  style reference in producing a docx file.  For best results, the
              reference docx should be a modified version of a docx file produced using pandoc.  The contents of
              the  reference  docx  are ignored, but its stylesheets 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, Block Text,
              Footnote Text, Definition Term, Definition, Caption, Table Caption, Image Caption, Figure,  Figure
              With  Caption,  TOC  Heading;  [character]  Default Paragraph Font, Body Text Char, Verbatim Char,
              Footnote Reference, Hyperlink; [table] Normal Table.

       --epub-stylesheet=FILE
              Use the specified CSS file to style the EPUB.  If no stylesheet is specified, pandoc will look for
              a  file  epub.css in the user data directory (see --data-dir).  If it is not found there, sensible
              defaults will be used.

       --epub-cover-image=FILE
              Use the specified image as the EPUB cover.  It is recommended that the image be less  than  1000px
              in  width and height.  Note that in a Markdown source document you can also specify cover-image in
              a YAML metadata block (see EPUB Metadata, 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 --epub-stylesheet):

                     @font-face {
                     font-family: DejaVuSans;
                     font-style: normal;
                     font-weight: normal;
                     src:url("DejaVuSans-Regular.ttf");
                     }
                     @font-face {
                     font-family: DejaVuSans;
                     font-style: normal;
                     font-weight: bold;
                     src:url("DejaVuSans-Bold.ttf");
                     }
                     @font-face {
                     font-family: DejaVuSans;
                     font-style: italic;
                     font-weight: normal;
                     src:url("DejaVuSans-Oblique.ttf");
                     }
                     @font-face {
                     font-family: DejaVuSans;
                     font-style: italic;
                     font-weight: bold;
                     src:url("DejaVuSans-BoldOblique.ttf");
                     }
                     body { font-family: "DejaVuSans"; }

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

       --latex-engine=pdflatex|lualatex|xelatex
              Use the specified LaTeX engine when producing PDF output.  The default is pdflatex.  If the engine
              is not in your PATH, the full path of the engine may be specified here.

       --latex-engine-opt=STRING
              Use  the given string as a command-line argument to the latex-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
       -m [URL], --latexmathml[=URL]
              Use LaTeXMathML to display embedded TeX math  in  HTML  output.   The  URL  should  point  to  the
              LaTeXMathML.js load script.  If a URL is not provided, a link to LaTeXMathML.js at the Homepage of
              LaTeXMathML will be inserted.

       --mathml[=URL]
              Convert TeX math to MathML (in docbook, docbook5, html and html5).  In standalone html  output,  a
              small  JavaScript  (or  a link to such a script if a URL is supplied) will be inserted that allows
              the MathML to be viewed on some browsers.

       --jsmath[=URL]
              Use jsMath to display embedded TeX math in HTML output.  The URL should point to the  jsMath  load
              script  (e.g.  jsMath/easy/load.js); if provided, it will be linked to in the header of standalone
              HTML documents.  If a URL is not provided, no link to the jsMath load script will be inserted;  it
              is then up to the author to provide such a link in the HTML template.

       --mathjax[=URL]
              Use  MathJax  to display embedded TeX math in HTML output.  The URL should point to the MathJax.js
              load script.  If a URL is not provided, a link to the MathJax CDN will be inserted.

       --gladtex
              Enclose TeX math in <eq> tags in HTML output.  These can then be processed by gladTeX  to  produce
              links to images of the typeset formulas.

       --mimetex[=URL]
              Render  TeX  math  using  the mimeTeX CGI script.  If URL is not specified, it is assumed that the
              script is at /cgi-bin/mimetex.cgi.

       --webtex[=URL]
              Render TeX formulas using an external script that converts TeX formulas to  images.   The  formula
              will  be  concatenated with the URL provided.  If URL is not specified, the CodeCogs will be used.
              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 should point to the katex.js load
              script.  If a URL is not provided, a link to the KaTeX CDN will be inserted.  Note: KaTeX seems to
              work best with html5 output.

       --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.

   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.beamer template, if you use
         -t beamer, or the default.context template, if you use -t context).

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

       Templates contain variables, which allow for the inclusion of arbitrary information at any point  in  the
       file.   Variables may be set within the document using YAML metadata blocks.  They may also be set at the
       command line using the -V/--variable option: variables set in this way override metadata fields with  the
       same name.

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

       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 and docx)

       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

   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.

       otherlangs
              a list of other languages used in the document in the YAML metadata, according  to  BCP  47.   For
              example: otherlangs: [en-GB, fr].  This is automatically generated from the lang attributes in all
              spans and divs but can be  overridden.   Currently  only  used  by  LaTeX  through  the  generated
              babel-otherlangs  and  polyglossia-otherlangs  variables.   The  LaTeX  writer outputs polyglossia
              commands in the text but  the  babel-newcommands  variable  contains  mappings  for  them  to  the
              corresponding babel.

       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
              --latex-engine=xelatex).

       hyphenate
              if true (the default), hyphenation will be used

   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 non-null value; otherwise it will include Y.  X and
       Y  are  placeholders  for  any  valid  template  text,  and  may  include interpolated variables or other
       conditionals.  The $else$ section may be omitted.

       When variables can have multiple values (for example, author in a multi-author document), you can use the
       $for$ keyword:

              $for(author)$
              <meta name="author" content="$author$" />
              $endfor$

       You can optionally specify a separator to be used between consecutive items:

              $for(author)$$author$$sep$, $endfor$

       A dot can be used to select a field of a variable that takes an object as its value.  So, for example:

              $author.name$ ($author.affiliation$)

       If  you  use  custom templates, you may need to revise them as pandoc changes.  We recommend tracking the
       changes in the default templates, and modifying your custom templates accordingly.  An  easy  way  to  do
       this is to fork the pandoc-templates repository and merge in changes after each pandoc release.

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

   Philosophy
       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.

   Header identifiers
   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: auto_identifiers
       A  header  without  an explicitly specified identifier will be automatically assigned a unique identifier
       based on the header text.  To derive the identifier from the header text,

       • Remove all formatting, links, etc.

       • Remove all footnotes.

       • Remove all punctuation, except underscores, hyphens, and periods.

       • Replace all spaces and newlines with hyphens.

       • Convert all alphabetic characters to lowercase.

       • Remove everything up to the first letter (identifiers may not begin with a number or punctuation mark).

       • If nothing is left after this, use the identifier section.

       Thus, for example,

       Header                       Identifier
       ────────────────────────────────────────────────────────
       Header identifiers in HTML   header-identifiers-in-html
       *Dogs*?--in *my* house?      dogs--in-my-house
       [HTML], [S5], or [RTF]?      html-s5-or-rtf
       3. Applications              applications
       33                           section

       These rules should, in most cases, allow one to determine the  identifier  from  the  header  text.   The
       exception  is  when several headers have the same text; in this case, the first will get an identifier as
       described above; the second will get the same identifier with -1 appended; the third with -2; and so on.

       These identifiers are  used  to  provide  link  targets  in  the  table  of  contents  generated  by  the
       --toc|--table-of-contents option.  They also make it easy to provide links from one section of a document
       to another.  A link to this section, for example, might look like this:

              See the section on
              [header identifiers](#header-identifiers-in-html-latex-and-context).

       Note, however, that this method of providing links to sections works only in  HTML,  LaTeX,  and  ConTeXt
       formats.

       If  the  --section-divs option is specified, then each section will be wrapped in a div (or a section, if
       --html5 was specified), and the identifier will be attached to the enclosing  <div>  (or  <section>)  tag
       rather than the header itself.  This allows entire sections to be manipulated using JavaScript or treated
       differently in CSS.

   Extension: implicit_header_references
       Pandoc behaves as if reference links have been defined for each header.  So, 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 and LaTeX.  If  highlighting  is  supported  for  your
       output  format and language, then the code block above will appear highlighted, with numbered lines.  (To
       see which languages are supported, 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>

       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.

   The four-space rule
       A list item  may  contain  multiple  paragraphs  and  other  block-level  content.   However,  subsequent
       paragraphs must be preceded by a blank line and indented four spaces or a tab.  The list will look better
       if the first paragraph is aligned with the rest:

                * First paragraph.

                  Continued.

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

                      { code }

       List items may include other lists.  In this case the preceding blank line is optional.  The nested  list
       must be indented four spaces or one tab:

              * fruits
                  + apples
                      - macintosh
                      - red delicious
                  + pears
                  + peaches
              * vegetables
                  + broccoli
                  + chard

       As  noted  above,  Markdown  allows  you  to write list items “lazily,” instead of indenting continuation
       lines.  However, if there are multiple paragraphs or other blocks in a list item, the first line of  each
       must be indented.

              + A lazy, lazy, list
              item.

              + Another one; this looks
              bad but is legal.

                  Second paragraph of second
              list item.

       Note:  Although  the  four-space rule for continuation paragraphs comes from the official Markdown syntax
       guide, the reference implementation, Markdown.pl, does not follow it.   So  pandoc  will  give  different
       results than Markdown.pl when authors have indented continuation paragraphs fewer than four spaces.

       The  Markdown syntax guide is not explicit whether the four-space rule applies to all block-level content
       in a list item; it only mentions paragraphs and code blocks.  But it implies that the rule applies to all
       block-level content (including nested lists), and pandoc interprets it that way.

   Ordered lists
       Ordered  lists  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.

   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
                  123     123       123          123
                    1     1          1             1

              Table:  Demonstration of simple table syntax.

       The  headers  and table rows must each fit on one line.  Column alignments are determined by the position
       of the header text relative to the dashed line below it:

       • 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:

       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           |
              +---------------+---------------+--------------------+

   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 cell contents will wrap, with the relative cell widths determined by the widths
       of the separator lines.

       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:

              ---
              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)$ ($author.affiliation$)$endif$
              $else$
              $author$
              $endif$
              $endfor$

   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.

   Smart punctuation
   Extension
       If  the  --smart  option  is  specified,  pandoc  will produce typographically correct output, converting
       straight quotes to curly quotes, --- to em-dashes, -- to en-dashes, and  ...  to  ellipses.   Nonbreaking
       spaces are inserted after certain abbreviations, such as “Mr.”

       Note:  if  your  LaTeX  template  or  any included header file call for the csquotes package, pandoc will
       detect this automatically and use \enquote{...} for quoted text.

   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, you can use an HTML span tag:

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

       (The semicolon is optional and there may be space after the colon.) This will work in all output  formats
       that support small caps.

       Alternatively, you can also use the new bracketed_spans syntax:

              [Small caps]{style="font-variant: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, ODT
              It will be rendered, if possible, using Unicode characters, and will otherwise appear verbatim.

       DocBook
              If  the  --mathml  flag  is  used,  it  will  be  rendered  using  MathML  in an inlineequation or
              informalequation tag.  Otherwise it will be rendered, if possible, using Unicode characters.

       Docx   It will be rendered using OMML math markup.

       FictionBook2
              If the --webtex option is used, formulas are rendered as images using 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:

              1. The  default  is  to  render TeX math as far as possible using Unicode characters, as with RTF,
                 DocBook, and OpenDocument output.  Formulas are put inside a span with  class="math",  so  that
                 they may be styled differently from the surrounding text if needed.

              2. If  the --latexmathml option is used, TeX math will be displayed between $ or $$ characters and
                 put in <span> tags with class LaTeX.  The LaTeXMathML script will  be  used  to  render  it  as
                 formulas.   (This  trick  does  not work in all browsers, but it works in Firefox.  In browsers
                 that do not support LaTeXMathML, TeX math will appear verbatim between $ characters.)

              3. If the --jsmath option is used, TeX math will be put inside <span> tags (for  inline  math)  or
                 <div> tags (for display math) with class math.  The jsMath script will be used to render it.

              4. If  the  --mimetex option is used, the mimeTeX CGI script will be called to generate images for
                 each TeX formula.  This should work in all browsers.  The --mimetex option  takes  an  optional
                 URL  as argument.  If no URL is specified, it will be assumed that the mimeTeX CGI script is at
                 /cgi-bin/mimetex.cgi.

              5. If the --gladtex option is used, TeX formulas will be enclosed in <eq> tags in the HTML output.
                 The  resulting  htex  file may then be processed by gladTeX, which will produce image files for
                 each formula and an HTML file with links to these images.  So, the procedure is:

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

              6. If the --webtex option is used, TeX formulas will be converted to <img> tags that  link  to  an
                 external  script  that  converts  formulas  to  images.   The  formula  will be URL-encoded and
                 concatenated with the URL provided.  If  no  URL  is  specified,  the  CodeCogs  will  be  used
                 (https://latex.codecogs.com/png.latex?).

              7. If  the  --mathjax option is used, TeX math will be displayed between \(...\) (for inline math)
                 or \[...\] (for display math) and put in <span> tags with class math.  The MathJax script  will
                 be used to render it as formulas.

   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.

   Raw TeX
   Extension: raw_tex
       In  addition to raw HTML, pandoc allows raw LaTeX, TeX, and ConTeXt to be included in a document.  Inline
       TeX commands will be preserved and passed unchanged to the LaTeX and ConTeXt writers.  Thus, for example,
       you can use LaTeX to include BibTeX citations:

              This result was proved in \cite{jones.1967}.

       Note that in LaTeX environments, like

              \begin{tabular}{|l|l|}\hline
              Age & Frequency \\ \hline
              18--25  & 15 \\
              26--35  & 33 \\
              36--45  & 22 \\ \hline
              \end{tabular}

       the material between the begin and end tags will be interpreted as raw LaTeX, not as Markdown.

       Inline LaTeX is ignored in output formats other than Markdown, LaTeX, Emacs Org mode, and ConTeXt.

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

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

              $\tuple{a, b, c}$

       In LaTeX output, the \newcommand definition will simply be passed unchanged to the output.

   Links
       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 can be
       space  between  the  two.) The link definition consists of the bracketed label, followed by a colon and a
       space, followed by the URL, and optionally  (after  a  space)  a  link  title  either  in  quotes  or  in
       parentheses.   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  occurring  by  itself in a paragraph will be rendered as a figure with a caption. (In LaTeX, a
       figure environment will be used; in HTML, the image will be placed in a div with class  figure,  together
       with a caption in a p with class caption.)  The image's alt text will be used as the caption.

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

       If  you  just want a regular inline image, just make sure it is not the only thing in the paragraph.  One
       way to do this is to insert a nonbreaking space after the image:

              ![This image won't be a figure](/url/of/image.png)\

   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.

   Spans
   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
                author:
                - family: Watson
                  given: J. D.
                - family: Crick
                  given: F. H. C.
                issued:
                  date-parts:
                  - - 1953
                    - 4
                    - 25
                title: 'Molecular structure of nucleic acids: a structure for deoxyribose
                  nucleic acid'
                title-short: Molecular structure of nucleic acids
                container-title: Nature
                volume: 171
                issue: 4356
                page: 737-738
                DOI: 10.1038/171737a0
                URL: http://www.nature.com/nature/journal/v171/n4356/abs/171737a0.html
                language: en-GB
              ...

       (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: 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: 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: ascii_identifiers
       Causes the identifiers produced by auto_identifiers to be  pure  ASCII.   Accents  are  stripped  off  of
       accented Latin letters, and non-Latin letters are omitted.

   Extension: 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.

       markdown_github (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.

       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.

       markdown_strict (Markdown.pl)
              raw_html

   Extensions with formats other than Markdown
       Some of the extensions discussed above can be used with formats other than Markdown:

       • auto_identifiers can be used with latex, rst, mediawiki, and textile input (and is used by default).

       • tex_math_dollars, tex_math_single_backslash, and tex_math_double_backslash can be used with html input.
         (This is handy for reading web pages formatted using MathJax, for example.)

PRODUCING SLIDE SHOWS WITH PANDOC

       You can use pandoc to produce an HTML + JavaScript slide presentation  that  can  be  viewed  via  a  web
       browser.   There  are  five  ways to do this, using S5, DZSlides, Slidy, Slideous, or reveal.js.  You can
       also produce a PDF slide show using LaTeX beamer.

       Here's the Markdown source for a simple slide show, habits.txt:

              % Habits
              % John Doe
              % March 22, 2005

              # In the morning

              ## Getting up

              - Turn off alarm
              - Get out of bed

              ## Breakfast

              - Eat eggs
              - Drink coffee

              # In the evening

              ## Dinner

              - Eat spaghetti
              - Drink wine

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

              ![picture of spaghetti](images/spaghetti.jpg)

              ## Going to sleep

              - Get in bed
              - Count sheep

       To produce an HTML/JavaScript slide show, simply type

              pandoc -t FORMAT -s habits.txt -o habits.html

       where FORMAT is either s5, slidy, slideous, dzslides, or revealjs.

       For Slidy, Slideous, reveal.js, and S5, the file produced  by  pandoc  with  the  -s/--standalone  option
       embeds  a  link  to  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.

   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.

       • 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 (that is, to display incrementally without the -i option and all at once with the -i option), put
       it in a block quote:

              > - Eat spaghetti
              > - Drink wine

       In this way incremental and nonincremental lists can be mixed in a single document.

   Inserting pauses
       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
       reveal.js has good support for speaker notes.  You can add notes to your Markdown document thus:

              <div class="notes">
              This is my note.

              - It can contain Markdown
              - like this list

              </div>

       To show the notes window, press s while viewing the presentation.  Notes are not yet supported for  other
       slide formats, but the notes will not appear on the slides themselves.

   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.

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
              rights: © 2007 John Smith, CC BY-NC
              ...

       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.

       subject
              A string value or a list of such values.

       description
              A string value.

       type   A string value.

       format A string value.

       relation
              A string value.

       coverage
              A string value.

       rights A string value.

       cover-image
              A string value (path to cover image).

       stylesheet
              A string value (path to CSS stylesheet).

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

   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>

LITERATE HASKELL SUPPORT

       If  you  append  +lhs  (or  +literate_haskell)  to  an  appropriate  input  or  output  format (markdown,
       markdown_strict, rst, or latex for input or output; beamer, html or html5 for output only),  pandoc  will
       treat the document as literate Haskell source.  This means that

       • In  Markdown  input, “bird track” sections will be parsed as Haskell code rather than block quotations.
         Text between \begin{code} and \end{code} will also be treated as Haskell code.  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.

SYNTAX HIGHLIGHTING

       Pandoc  will  automatically  highlight syntax in fenced code blocks that are marked with a language name.
       The Haskell library highlighting-kate is used for highlighting, which works in HTML, Docx, 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 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,

              <span custom-style="Emphatically">Get out,</span> he said.

       would produce a docx file with “Get out,” styled with character style Emphatically.  Similarly,

              Dickinson starts the poem simply:

              <div custom-style="Poetry">
              | A Bird came down the Walk---
              | He did not know I saw---
              </div>

       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
