1313Pandoc is a [Haskell] library for converting from one markup format to
14−another, and a command-line tool that uses this library.

16−Pandoc can convert between numerous markup and word processing formats,
17−including, but not limited to, various flavors of [Markdown], [HTML],
18−[LaTeX] and [Word docx]. For the full lists of input and output formats,
19−see the `--from` and `--to` [options below][General options].
20−Pandoc can also produce [PDF] output: see [creating a PDF], below.

41+
42+In contrast to most existing tools for converting Markdown to HTML, which
43+use regex substitutions, pandoc has a modular design: it consists of a
44+set of readers, which parse text in a given format and produce a native
45+representation of the document, and a set of writers, which convert

17651243
1766−### Comments
1244+`sourcefile`, `outputfile`

1327+`lang`
1328+: identifies the main language of the document,
1329+ using a code according to [BCP 47] (e.g. `en` or `en-GB`).
1330+ For some output formats, pandoc will convert it to an appropriate
1331+ format stored in the additional variables `babel-lang`,
1332+ `polyglossia-lang` (LaTeX) and `context-lang` (ConTeXt).
1333+
1334+ Native pandoc `span`s and `div`s with the lang attribute
1335+ (value in BCP 47) can be used to switch the language in
1336+ that range.
1337+
1338+`otherlangs`
1339+: a list of other languages used in the document
1340+ in the YAML metadata, according to [BCP 47]. For example:
1341+ `otherlangs: [en-GB, fr]`.
1342+ This is automatically generated from the `lang` attributes
1343+ in all `span`s and `div`s but can be overridden.
1344+ Currently only used by LaTeX through the generated
1345+ `babel-otherlangs` and `polyglossia-otherlangs` variables.
1346+ The LaTeX writer outputs polyglossia commands in the text but
1347+ the `babel-newcommands` variable contains mappings for them
1348+ to the corresponding babel.
18631349
1864−### For loops
1350+`dir`
1351+: the base direction of the document, either `rtl` (right-to-left)
1352+ or `ltr` (left-to-right).
18651353
1866−A for loop begins with `for(variable)` (enclosed in
1867−matched delimiters) and ends with `endfor` (enclosed in matched
1868−delimiters.
1354+ For bidirectional documents, native pandoc `span`s and `div`s
1355+ with the `dir` attribute (value `rtl` or `ltr`) can be used to
1356+ override the base direction in some output formats.
1357+ This may not always be necessary if the final renderer
1358+ (e.g. the browser, when generating HTML) supports the
1359+ [Unicode Bidirectional Algorithm].
18691360
1870−- If `variable` is an array, the material inside the loop will
1871− be evaluated repeatedly, with `variable` being set to each
1872− value of the array in turn, and concatenated.
1873−- If `variable` is a map, the material inside will be set to
1874− the map.
1875−- If the value of the associated variable is not an array or
1876− a map, a single iteration will be performed on its value.

1426+`fontsize`
1427+: font size for body text (e.g. `10pt`, `12pt`)
19561428
1957−Note that the anaphoric keyword `it` must be used when
1958−iterating over partials. In the above examples,
1959−the `bibentry` partial should contain `it.title`
1960−(and so on) instead of `articles.title`.

1661+conditionals. The `$else$` section may be omitted.
22011662
2202−`lang`
2203−: identifies the main language of the document using IETF language
2204− tags (following the [BCP 47] standard), such as `en` or `en-GB`.
2205− The [Language subtag lookup] tool can look up or verify these tags.
2206− This affects most formats, and controls hyphenation in PDF output
2207− when using LaTeX (through [`babel`] and [`polyglossia`]) or ConTeXt.
1663+When variables can have multiple values (for example, `author` in

22171674
2218− ::: {lang=fr-CA}
2219− > Cette citation est écrite en français canadien.
2220− :::
1675+A dot can be used to select a field of a variable that takes

2224−`dir`
2225−: the base script direction, either `rtl` (right-to-left)
2226− or `ltr` (left-to-right).
1680+If you use custom templates, you may need to revise them as pandoc
1681+changes. We recommend tracking the changes in the default templates,
1682+and modifying your custom templates accordingly. An easy way to do this
1683+is to fork the [pandoc-templates] repository and merge in changes after each
1684+pandoc release.
22271685
2228− For bidirectional documents, native pandoc `span`s and
2229− `div`s with the `dir` attribute (value `rtl` or `ltr`) can
2230− be used to override the base direction in some output
2231− formats. This may not always be necessary if the final
2232− renderer (e.g. the browser, when generating HTML) supports
2233− the [Unicode Bidirectional Algorithm].
1686+Templates may contain comments: anything on a line after `$--`
1687+will be treated as a comment and ignored.
22341688
2235− When using LaTeX for bidirectional documents, only the
2236− `xelatex` engine is fully supported (use
2237− `--pdf-engine=xelatex`).

1691+Extensions
1692+==========
22421693
2243−### Variables for HTML
1694+The behavior of some of the readers and writers can be adjusted by
1695+enabling or disabling various extensions.
22441696
2245−`document-css`
2246−: Enables inclusion of most of the [CSS] in the `styles.html`
2247− [partial](#partials) (have a look with
2248− `pandoc --print-default-data-file=templates/styles.html`).
2249− Unless you use [`--css`](#option--css), this variable
2250− is set to `true` by default. You can disable it with
2251− e.g. `pandoc -M document-css=false`.
1697+An extension can be enabled by adding `+EXTENSION`
1698+to the format name and disabled by adding `-EXTENSION`. For example,
1699+`--from markdown_strict+footnotes` is strict Markdown with footnotes
1700+enabled, while `--from markdown-footnotes-pipe_tables` is pandoc's
1701+Markdown without footnotes or pipe tables.
22521702
2253−`mainfont`
2254−: sets the CSS `font-family` property on the `html` element.
1703+The markdown reader and writer make by far the most use of extensions.
1704+Extensions only used by them are therefore covered in the
1705+section [Pandoc's Markdown] below (See [Markdown variants] for
1706+`commonmark` and `gfm`.) In the following, extensions that also work
1707+for other formats are covered.
22551708
2256−`fontsize`
2257−: sets the base CSS `font-size`, which you'd usually set
2258− to e.g. `20px`, but it also accepts `pt`
2259− (12pt = 16px in most browsers).
1709+Typography
1710+----------
22601711
2261−`fontcolor`
2262−: sets the CSS `color` property on the `html` element.
1712+#### Extension: `smart` ####
22631713
2264−`linkcolor`
2265−: sets the CSS `color` property on all links.
1714+Interpret straight quotes as curly quotes, `---` as em-dashes,
1715+`--` as en-dashes, and `...` as ellipses. Nonbreaking spaces are
1716+inserted after certain abbreviations, such as "Mr."
22661717
2267−`monofont`
2268−: sets the CSS `font-family` property on `code` elements.
1718+This extension can be enabled/disabled for the following formats:
22691719
2270−`monobackgroundcolor`
2271−: sets the CSS `background-color` property on `code` elements
2272− and adds extra padding.
1720+input formats
1721+: `markdown`, `commonmark`, `latex`, `mediawiki`, `org`, `rst`, `twiki`
22731722
2274−`linestretch`
2275−: sets the CSS `line-height` property on the `html` element,
2276− which is preferred to be unitless.
1723+output formats
1724+: `markdown`, `latex`, `context`, `rst`
22771725
2278−`backgroundcolor`
2279−: sets the CSS `background-color` property on the `html` element.
1726+enabled by default in
1727+: `markdown`, `latex`, `context` (both input and output)
22801728
2281−`margin-left`, `margin-right`, `margin-top`, `margin-bottom`
2282−: sets the corresponding CSS `padding` properties on the `body` element.
1729+Note: If you are *writing* Markdown, then the `smart` extension
1730+has the reverse effect: what would have been curly quotes comes
1731+out straight.
22831732
2284−To override or extend some [CSS] for just one document, include for example:
1733+In LaTeX, `smart` means to use the standard TeX ligatures
1734+for quotation marks (` `` ` and ` '' ` for double quotes,
1735+`` ` `` and `` ' `` for single quotes) and dashes (`--` for
1736+en-dash and `---` for em-dash). If `smart` is disabled,
1737+then in reading LaTeX pandoc will parse these characters
1738+literally. In writing LaTeX, enabling `smart` tells pandoc
1739+to use the ligatures when possible; if `smart` is disabled
1740+pandoc will use unicode quotation mark and dash characters.

1742+Headers and sections
1743+--------------------
23031744
2304−[CSS]: https://developer.mozilla.org/en-US/docs/Learn/CSS
1745+#### Extension: `auto_identifiers` ####
23051746
2306−### Variables for HTML math
1747+A header without an explicitly specified identifier will be
1748+automatically assigned a unique identifier based on the header text.
23071749
2308−`classoption`
2309−: when using [KaTeX](#option--katex), you can render display
2310−math equations flush left using [YAML metadata](#layout) or with
2311−`-M classoption=fleqn`.
1750+This extension can be enabled/disabled for the following formats:
23121751
2313−### Variables for HTML slides
1752+input formats
1753+: `markdown`, `latex`, `rst`, `mediawiki`, `textile`
23141754
2315−These affect HTML output when [producing slide shows with pandoc].
1755+output formats
1756+: `markdown`, `muse`
23161757
2317−`institute`
2318−: author affiliations: can be a list when there are multiple authors
1758+enabled by default in
1759+: `markdown`, `muse`
23191760
2320−`revealjs-url`
2321−: base URL for reveal.js documents (defaults to
2322− `https://unpkg.com/reveal.js@^4/`)
1761+The algorithm used to derive the identifier from the header text is:
23231762
2324−`s5-url`
2325−: base URL for S5 documents (defaults to `s5/default`)
1763+ - Remove all formatting, links, etc.
1764+ - Remove all footnotes.
1765+ - Remove all punctuation, except underscores, hyphens, and periods.
1766+ - Replace all spaces and newlines with hyphens.
1767+ - Convert all alphabetic characters to lowercase.
1768+ - Remove everything up to the first letter (identifiers may
1769+ not begin with a number or punctuation mark).
1770+ - If nothing is left after this, use the identifier `section`.
23261771
2327−`slidy-url`
2328−: base URL for Slidy documents (defaults to
2329− `https://www.w3.org/Talks/Tools/Slidy2`)
1772+Thus, for example,
23301773
2331−`slideous-url`
2332−: base URL for Slideous documents (defaults to `slideous`)
1774+ Header Identifier
1775+ ------------------------------- ----------------------------
1776+ `Header identifiers in HTML` `header-identifiers-in-html`
1777+ `*Dogs*?--in *my* house?` `dogs--in-my-house`
1778+ `[HTML], [S5], or [RTF]?` `html-s5-or-rtf`
1779+ `3. Applications` `applications`
1780+ `33` `section`
23331781
2334−`title-slide-attributes`
2335−: additional attributes for the title slide of reveal.js slide shows.
2336− See [background in reveal.js and beamer] for an example.
1782+These rules should, in most cases, allow one to determine the identifier
1783+from the header text. The exception is when several headers have the
1784+same text; in this case, the first will get an identifier as described
1785+above; the second will get the same identifier with `-1` appended; the
1786+third with `-2`; and so on.
23371787
2338−All [reveal.js configuration options] are available as variables.
2339−To turn off boolean flags that default to true in reveal.js, use `0`.
1788+These identifiers are used to provide link targets in the table of
1789+contents generated by the `--toc|--table-of-contents` option. They
1790+also make it easy to provide links from one section of a document to
1791+another. A link to this section, for example, might look like this:
23401792
2341−[reveal.js configuration options]: https://revealjs.com/config/
1793+ See the section on
1794+ [header identifiers](#header-identifiers-in-html-latex-and-context).
23421795
2343−### Variables for Beamer slides
1796+Note, however, that this method of providing links to sections works
1797+only in HTML, LaTeX, and ConTeXt formats.
23441798
2345−These variables change the appearance of PDF slides using [`beamer`].
1799+If the `--section-divs` option is specified, then each section will
1800+be wrapped in a `div` (or a `section`, if `html5` was specified),
1801+and the identifier will be attached to the enclosing `<div>`
1802+(or `<section>`) tag rather than the header itself. This allows entire
1803+sections to be manipulated using JavaScript or treated differently in
1804+CSS.
23461805
2347−`aspectratio`
2348−: slide aspect ratio (`43` for 4:3 [default], `169` for 16:9,
2349− `1610` for 16:10, `149` for 14:9, `141` for 1.41:1, `54` for 5:4,
2350− `32` for 3:2)
1806+#### Extension: `ascii_identifiers` ####
23511807
2352−`beamerarticle`
2353−: produce an article from Beamer slides
1808+Causes the identifiers produced by `auto_identifiers` to be pure ASCII.
1809+Accents are stripped off of accented Latin letters, and non-Latin
1810+letters are omitted.
23541811
2355−`beameroption`
2356−: add extra beamer option with `\setbeameroption{}`
1812+Math Input
1813+----------
23571814
2358−`institute`
2359−: author affiliations: can be a list when there are multiple authors
1815+The extensions [`tex_math_dollars`](#extension-tex_math_dollars),
1816+[`tex_math_single_backslash`](#extension-tex_math_single_backslash), and
1817+[`tex_math_double_backslash`](#extension-tex_math_double_backslash)
1818+are described in the section about Pandoc's Markdown.
23601819
2361−`logo`
2362−: logo image for slides
1820+However, they can also be used with HTML input. This is handy for
1821+reading web pages formatted using MathJax, for example.
23631822
2364−`navigation`
2365−: controls navigation symbols (default is `empty` for no navigation
2366− symbols; other valid values are `frame`, `vertical`, and `horizontal`)
1823+Raw HTML/TeX
1824+------------
23671825
2368−`section-titles`
2369−: enables "title pages" for new sections (default is true)
1826+The following extensions (especially how they affect Markdown
1827+input/output) are also described in more detail in their respective
1828+sections of [Pandoc's Markdown].
23701829
2371−`theme`, `colortheme`, `fonttheme`, `innertheme`, `outertheme`
2372−: beamer themes
1830+#### [Extension: `raw_html`] {#raw_html}
23731831
2374−`themeoptions`
2375−: options for LaTeX beamer themes (a list).
1832+When converting from HTML, parse elements to raw HTML which are not
1833+representable in pandoc's AST.
1834+By default, this is disabled for HTML input.
23761835
2377−`titlegraphic`
2378−: image for title slide
1836+#### [Extension: `raw_tex`] {#raw_tex}
23791837
2380−### Variables for PowerPoint
1838+Allows raw LaTeX, TeX, and ConTeXt to be included in a document.
23811839
2382−These variables control the visual aspects of a slide show that
2383−are not easily controlled via templates.
1840+This extension can be enabled/disabled for the following formats
1841+(in addition to `markdown`):
23841842
2385−`monofont`
2386−: font to use for code.
1843+input formats
1844+: `latex`, `org`, `textile`
23871845
2388−### Variables for LaTeX
1846+output formats
1847+: `textile`
23891848
2390−Pandoc uses these variables when [creating a PDF] with a LaTeX engine.
1849+#### [Extension: `native_divs`] {#native_divs}
23911850
2392−#### Layout
1851+This extension is enabled by default for HTML input. This means that
1852+`div`s are parsed to pandoc native elements. (Alternatively, you
1853+can parse them to raw HTML using `-f html-native_divs+raw_html`.)
23931854
2394−`block-headings`
2395−: make `\paragraph` and `\subparagraph` (fourth- and
2396− fifth-level headings, or fifth- and sixth-level with book
2397− classes) free-standing rather than run-in; requires further
2398− formatting to distinguish from `\subsubsection` (third- or
2399− fourth-level headings). Instead of using this option,
2400− [KOMA-Script] can adjust headings more extensively:
1855+When converting HTML to Markdown, for example, you may want to drop all
1856+`div`s and `span`s:

2429− default to smaller margins; or [`memoir`]
24301864
2431−`geometry`

24451871
2446− ---

2449− - pdfwindowui
2450− - pdfpagemode=FullScreen
2451− ...
2452−
2453−`indent`
2454−: if true, pandoc will use document class settings for
2455− indentation (the default LaTeX template otherwise removes
2456− indentation and adds space between paragraphs)
1872+This extension can be enabled/disabled for the following formats:
24571873
2458−`linestretch`
2459−: adjusts line spacing using the [`setspace`]
2460− package, e.g. `1.25`, `1.5`
1874+input formats
1875+: `markdown`, `rst`, `latex`
24611876
2462−`margin-left`, `margin-right`, `margin-top`, `margin-bottom`
2463−: sets margins if `geometry` is not used (otherwise `geometry`
2464− overrides these)
1877+output formats
1878+: `markdown`, `rst`, `latex`, `html`
24651879
2466−`pagestyle`
2467−: control `\pagestyle{}`: the default article class
2468− supports `plain` (default), `empty` (no running heads or page numbers),
2469− and `headings` (section titles in running heads)
1880+If you append `+lhs` (or `+literate_haskell`) to one of the formats
1881+above, pandoc will treat the document as literate Haskell source.
1882+This means that
24701883
2471−`papersize`
2472−: paper size, e.g. `letter`, `a4`
1884+ - In Markdown input, "bird track" sections will be parsed as Haskell
1885+ code rather than block quotations. Text between `\begin{code}`
1886+ and `\end{code}` will also be treated as Haskell code. For
1887+ ATX-style headers the character '=' will be used instead of '#'.
24731888
2474−`secnumdepth`
2475−: numbering depth for sections (with `--number-sections` option
2476− or `numbersections` variable)
1889+ - In Markdown output, code blocks with classes `haskell` and `literate`
1890+ will be rendered using bird tracks, and block quotations will be
1891+ indented one space, so they will not be treated as Haskell code.
1892+ In addition, headers will be rendered setext-style (with underlines)
1893+ rather than ATX-style (with '#' characters). (This is because ghc
1894+ treats '#' characters in column 1 as introducing line numbers.)
24771895
2478−#### Fonts
1896+ - In restructured text input, "bird track" sections will be parsed
1897+ as Haskell code.
24791898
2480−`fontenc`
2481−: allows font encoding to be specified through `fontenc` package (with
2482− `pdflatex`); default is `T1` (see [LaTeX font encodings guide])
1899+ - In restructured text output, code blocks with class `haskell` will
1900+ be rendered using bird tracks.
24831901
2484−`fontfamily`
2485−: font package for use with `pdflatex`:
2486− [TeX Live] includes many options, documented in the [LaTeX Font Catalogue].
2487− The default is [Latin Modern][`lm`].
1902+ - In LaTeX input, text in `code` environments will be parsed as
1903+ Haskell code.
24881904
2489−`fontfamilyoptions`
2490−: options for package used as `fontfamily`; repeat for multiple options.
2491− For example, to use the Libertine font with proportional lowercase
2492− (old-style) figures through the [`libertinus`] package:
1905+ - In LaTeX output, code blocks with class `haskell` will be rendered
1906+ inside `code` environments.
24931907
2494− ---
2495− fontfamily: libertinus
2496− fontfamilyoptions:
2497− - osf
2498− - p
2499− ...
1908+ - In HTML output, code blocks with class `haskell` will be rendered
1909+ with class `literatehaskell` and bird tracks.
25001910
2501−`fontsize`
2502−: font size for body text. The standard classes allow 10pt, 11pt, and
2503− 12pt. To use another size, set `documentclass` to one of
2504− the [KOMA-Script] classes, such as `scrartcl` or `scrbook`.
1911+Examples:
25051912
2506−`mainfont`, `sansfont`, `monofont`, `mathfont`, `CJKmainfont`
2507−: font families for use with `xelatex` or
2508− `lualatex`: take the name of any system font, using the
2509− [`fontspec`] package. `CJKmainfont` uses the [`xecjk`] package.
1913+ pandoc -f markdown+lhs -t html
25101914
2511−`mainfontoptions`, `sansfontoptions`, `monofontoptions`, `mathfontoptions`, `CJKoptions`
2512−: options to use with `mainfont`, `sansfont`, `monofont`, `mathfont`,
2513− `CJKmainfont` in `xelatex` and `lualatex`. Allow for any
2514− choices available through [`fontspec`]; repeat for multiple
2515− options. For example, to use the [TeX Gyre] version of
2516− Palatino with lowercase figures:
1915+reads literate Haskell source formatted with Markdown conventions and writes
1916+ordinary HTML (without bird tracks).
25171917
2518− ---
2519− mainfont: TeX Gyre Pagella
2520− mainfontoptions:
2521− - Numbers=Lowercase
2522− - Numbers=Proportional
2523− ...
1918+ pandoc -f markdown+lhs -t html+lhs
25241919
2525−`microtypeoptions`
2526−: options to pass to the microtype package
1920+writes HTML with the Haskell code in bird tracks, so it can be copied
1921+and pasted as literate Haskell source.
25271922
2528−#### Links
1923+Note that GHC expects the bird tracks in the first column, so indentend literate
1924+code blocks (e.g. inside an itemized environment) will not be picked up by the
1925+Haskell compiler.
25291926
2530−`colorlinks`
2531−: add color to link text; automatically enabled if any of
2532− `linkcolor`, `filecolor`, `citecolor`, `urlcolor`, or `toccolor` are set
1927+Other extensions
1928+----------------
25331929
2534−`linkcolor`, `filecolor`, `citecolor`, `urlcolor`, `toccolor`

2587−### Variables for ConTeXt
1976+This principle has guided pandoc's decisions in finding syntax for
1977+tables, footnotes, and other extensions.
25881978
2589−Pandoc uses these variables when [creating a PDF] with ConTeXt.
1979+There is, however, one respect in which pandoc's aims are different
1980+from the original aims of Markdown. Whereas Markdown was originally
1981+designed with HTML generation in mind, pandoc is designed for multiple
1982+output formats. Thus, while pandoc allows the embedding of raw HTML,
1983+it discourages it, and provides other, non-HTMLish ways of representing
1984+important document elements like definition lists, tables, mathematics, and
1985+footnotes.
25901986
2591−`fontsize`
2592−: font size for body text (e.g. `10pt`, `12pt`)
1987+Paragraphs

25931989
2594−`headertext`, `footertext`
2595−: text to be placed in running header or footer (see [ConTeXt Headers and
2596− Footers]); repeat up to four times for different placement
1990+A paragraph is one or more lines of text followed by one or more blank lines.
1991+Newlines are treated as spaces, so you can reflow your paragraphs as you like.
1992+If you need a hard line break, put two or more spaces at the end of a line.
25971993
2598−`indenting`
2599−: controls indentation of paragraphs, e.g. `yes,small,next` (see
2600− [ConTeXt Indentation]); repeat for multiple options
1994+#### Extension: `escaped_line_breaks` ####

2602−`interlinespace`
2603−: adjusts line spacing, e.g. `4ex` (using [`setupinterlinespace`]);
2604− repeat for multiple options
1996+A backslash followed by a newline is also a hard line break.
1997+Note: in multiline and grid table cells, this is the only way
1998+to create a hard line break, since trailing spaces in the cells
1999+are ignored.
26052000
2606−`layout`
2607−: options for page margins and text arrangement (see [ConTeXt Layout]);
2608− repeat for multiple options

2610−`linkcolor`, `contrastcolor`
2611−: color for links outside and inside a page, e.g. `red`, `blue` (see
2612− [ConTeXt Color])
2004+There are two kinds of headers: Setext and ATX.
26132005
2614−`linkstyle`
2615−: typeface style for links, e.g. `normal`, `bold`, `slanted`, `boldslanted`,

26172007
2618−`lof`, `lot`

2008+A setext-style header is a line of text "underlined" with a row of `=` signs
2009+(for a level one header) or `-` signs (for a level two header):
26202010
2621−`mainfont`, `sansfont`, `monofont`, `mathfont`

26322019
2633−`papersize`
2634−: paper size, e.g. `letter`, `A4`, `landscape` (see [ConTeXt Paper Setup]);
2635− repeat for multiple options
2636−
2637−`pdfa`
2638−: adds to the preamble the setup necessary to generate PDF/A
2639− of the type specified, e.g. `1a:2005`, `2a`. If no type is
2640− specified (i.e. the value is set to True, by e.g.
2641− `--metadata=pdfa` or `pdfa: true` in a YAML metadata block),
2642− `1b:2005` will be used as default, for reasons of backwards
2643− compatibility. Using `--variable=pdfa` without specified value
2644− is not supported. To successfully generate PDF/A the required
2645− ICC color profiles have to be available and the content and all
2646− included files (such as images) have to be standard conforming.
2647− The ICC profiles and output intent may be specified using the
2648− variables `pdfaiccprofile` and `pdfaintent`. See also [ConTeXt
2649− PDFA] for more details.
2650−
2651−`pdfaiccprofile`
2652−: when used in conjunction with `pdfa`, specifies the ICC profile to use
2653− in the PDF, e.g. `default.cmyk`. If left unspecified, `sRGB.icc` is
2654− used as default. May be repeated to include multiple profiles. Note that
2655− the profiles have to be available on the system. They can be obtained
2656− from [ConTeXt ICC Profiles].
2657−
2658−`pdfaintent`
2659−: when used in conjunction with `pdfa`, specifies the output intent for
2660− the colors, e.g. `ISO coated v2 300\letterpercent\space (ECI)`
2661− If left unspecified, `sRGB IEC61966-2.1` is used as default.
26622020

2023+An ATX-style header consists of one to six `#` signs and a line of
2024+text, optionally followed by any number of `#` signs. The number of

2037+Standard Markdown syntax does not require a blank line before a header.
2038+Pandoc does require this (except, of course, at the beginning of the
2039+document). The reason for the requirement is that it is all too easy for a
2040+`#` to end up at the beginning of a line by accident (perhaps through line
2041+wrapping). Consider, for example:
26962042
2697−`papersize`
2698−: sets the PDF paper size

27012047
2702−`adjusting`
2703−: adjusts text to left (`l`), right (`r`), center (`c`),
2704− or both (`b`) margins
2048+Many Markdown implementations do not require a space between the
2049+opening `#`s of an ATX header and the header text, so that
2050+`#5 bolt` and `#hashtag` count as headers. With this extension,
2051+pandoc does require the space.
27052052
2706−`footer`
2707−: footer in man pages
2053+### Header identifiers ###
27082054
2709−`header`
2710−: header in man pages
2055+See also the [`auto_identifiers` extension](#extension-auto_identifiers) above.
27112056
2712−`hyphenate`
2713−: if `true` (the default), hyphenation will be used
2057+#### Extension: `header_attributes` ####
27142058
2715−`section`
2716−: section number in man pages
2059+Headers can be assigned attributes using this syntax at the end
2060+of the line containing the header text:
27172061
2718−### Variables for ms
2062+ {#identifier .class .class key=value key=value}
27192063
2720−`fontfamily`

2064+Thus, for example, the following headers will all be assigned the identifier
2065+`foo`:
27222066
2723−`indent`
2724−: paragraph indent (e.g. `2m`)
2067+ # My header {#foo}

27312073
2732−### Variables set automatically
2074+(This syntax is compatible with [PHP Markdown Extra].)
27332075
2734−Pandoc sets these variables automatically in response to [options] or
2735−document contents; users can also modify them. These vary depending
2736−on the output format, and include the following:
2076+Note that although this syntax allows assignment of classes and key/value
2077+attributes, writers generally don't use all of this information. Identifiers,
2078+classes, and key/value attributes are used in HTML and HTML-based formats such
2079+as EPUB and slidy. Identifiers are used for labels and link anchors in the
2080+LaTeX, ConTeXt, Textile, and AsciiDoc writers.
27372081
2738−`body`
2739−: body of document
2082+Headers with the class `unnumbered` will not be numbered, even if
2083+`--number-sections` is specified. A single hyphen (`-`) in an attribute
2084+context is equivalent to `.unnumbered`, and preferable in non-English
2085+documents. So,
27402086
2741−`date-meta`
2742−: the `date` variable converted to ISO 8601 YYYY-MM-DD,
2743− included in all HTML based formats (dzslides, epub,
2744− html, html4, html5, revealjs, s5, slideous, slidy).
2745− The recognized formats for `date` are: `mm/dd/yyyy`,
2746− `mm/dd/yy`, `yyyy-mm-dd` (ISO 8601), `dd MM yyyy`
2747− (e.g. either `02 Apr 2018` or `02 April 2018`),
2748− `MM dd, yyyy` (e.g. `Apr. 02, 2018` or `April 02, 2018),
2749− `yyyy[mm[dd]]]` (e.g. `20180402, `201804` or `2018`).
2087+ # My header {-}
27502088
2751−`header-includes`
2752−: contents specified by `-H/--include-in-header` (may have multiple
2753− values)
2089+is just the same as
27542090
2755−`include-before`

2763−`meta-json`
2764−: JSON representation of all of the document's metadata. Field

2771−: source and destination filenames, as given on the command line.
2772− `sourcefile` can also be a list if input comes from multiple files,

2119+links to link to the others, as described above.
28012120
2802−The behavior of some of the readers and writers can be adjusted by
2803−enabling or disabling various extensions.
2121+Like regular reference links, these references are case-insensitive.
28042122
2805−An extension can be enabled by adding `+EXTENSION`

2808−enabled, while `--from markdown-footnotes-pipe_tables` is pandoc's
2809−Markdown without footnotes or pipe tables.
2123+Explicit link reference definitions always take priority over
2124+implicit header references. So, in the following example, the
2125+link will point to `bar`, not to `#foo`:

2136+Markdown uses email conventions for quoting blocks of text.
2137+A block quotation is one or more paragraphs or other block elements
2138+(such as lists or headers), with each line preceded by a `>` character
2139+and an optional space. (The `>` need not start at the left margin, but

2857−A heading without an explicitly specified identifier will be
2858−automatically assigned a unique identifier based on the heading text.
2164+If the `>` character is followed by an optional space, that space
2165+will be considered part of the block quote marker and not part of
2166+the indentation of the contents. Thus, to put an indented code
2167+block in a block quote, you need five spaces after the `>`:

2173+Standard Markdown syntax does not require a blank line before a block
2174+quote. Pandoc does require this (except, of course, at the beginning of the
2175+document). The reason for the requirement is that it is all too easy for a
2176+`>` to end up at the beginning of a line by accident (perhaps through line
2177+wrapping). So, unless the `markdown_strict` format is used, the following does
2178+not produce a nested block quote in pandoc:

28702182
2871−The default algorithm used to derive the identifier from the
2872−heading text is:
28732183
2874− - Remove all formatting, links, etc.
2875− - Remove all footnotes.
2876− - Remove all non-alphanumeric characters,
2877− except underscores, hyphens, and periods.
2878− - Replace all spaces and newlines with hyphens.
2879− - Convert all alphabetic characters to lowercase.
2880− - Remove everything up to the first letter (identifiers may
2881− not begin with a number or punctuation mark).

2904−These identifiers are used to provide link targets in the table of
2905−contents generated by the `--toc|--table-of-contents` option. They

3164−## Philosophy
2464+Pandoc also pays attention to the type of list marker used, and to the
2465+starting number, and both of these are preserved where possible in the
2466+output format. Thus, the following yields a list with numbers followed
2467+by a single parenthesis, starting with 9, and a sublist with lowercase
2468+roman numerals:
31652469
3166−Markdown is designed to be easy to write, and, even more importantly,
3167−easy to read:
2470+ 9) Ninth
2471+ 10) Tenth
2472+ 11) Eleventh

3171−> instructions.
3172−> -- [John Gruber](https://daringfireball.net/projects/markdown/syntax#philosophy)
2477+Pandoc will start a new list each time a different type of list
2478+marker is used. So, the following will create three lists:
31732479
3174−This principle has guided pandoc's decisions in finding syntax for

31762484
3177−There is, however, one respect in which pandoc's aims are different
3178−from the original aims of Markdown. Whereas Markdown was originally
3179−designed with HTML generation in mind, pandoc is designed for multiple
3180−output formats. Thus, while pandoc allows the embedding of raw HTML,
3181−it discourages it, and provides other, non-HTMLish ways of representing
3182−important document elements like definition lists, tables, mathematics, and
3183−footnotes.
2485+If default list markers are desired, use `#.`:

31862490

3188−Newlines are treated as spaces, so you can reflow your paragraphs as you like.

2496+Pandoc supports definition lists, using the syntax of
2497+[PHP Markdown Extra] with some extensions.[^3]
31992498
3200−There are two kinds of headings: Setext and ATX.
2499+ Term 1
32012500
3202−### Setext-style headings ###
2501+ : Definition 1
32032502
3204−A setext-style heading is a line of text "underlined" with a row of `=` signs
3205−(for a level-one heading) or `-` signs (for a level-two heading):
2503+ Term 2 with *inline markup*
32062504
3207− A level-one heading
3208− ===================
2505+ : Definition 2
32092506
3210− A level-two heading
3211− -------------------
2507+ { some code, part of Definition 2 }
32122508
3213−The heading text can contain inline formatting, such as emphasis (see
3214−[Inline formatting], below).
2509+ Third paragraph of definition 2.
32152510
2511+Each term must fit on one line, which may optionally be followed by
2512+a blank line, and must be followed by one or more definitions.
2513+A definition begins with a colon or tilde, which may be indented one
2514+or two spaces.
32162515
3217−### ATX-style headings ###
2516+A term may have multiple definitions, and each definition may consist of one or
2517+more block elements (paragraph, code block, list, etc.), each indented four
2518+spaces or one tab stop. The body of the definition (including the first line,
2519+aside from the colon or tilde) should be indented four spaces. However,
2520+as with other Markdown lists, you can "lazily" omit indentation except
2521+at the beginning of a paragraph or other block element:
32182522
3219−An ATX-style heading consists of one to six `#` signs and a line of
3220−text, optionally followed by any number of `#` signs. The number of
3221−`#` signs at the beginning of the line is the heading level:
2523+ Term 1
32222524
3223− ## A level-two heading
2525+ : Definition
2526+ with lazy continuation.
32242527
3225− ### A level-three heading ###
2528+ Second paragraph of the definition.
32262529
3227−As with setext-style headings, the heading text can contain formatting:
2530+If you leave space before the definition (as in the example above),
2531+the text of the definition will be treated as a paragraph. In some
2532+output formats, this will mean greater spacing between term/definition
2533+pairs. For a more compact definition list, omit the space before the
2534+definition:
32282535
3229− # A level-one heading with a [link](/url) and *emphasis*

2539+ Term 2
2540+ ~ Definition 2a
2541+ ~ Definition 2b
32322542
3233−Standard Markdown syntax does not require a blank line before a heading.
3234−Pandoc does require this (except, of course, at the beginning of the
3235−document). The reason for the requirement is that it is all too easy for a
3236−`#` to end up at the beginning of a line by accident (perhaps through line
3237−wrapping). Consider, for example:
2543+Note that space between items in a definition list is required.
2544+(A variant that loosens this requirement, but disallows "lazy"
2545+hard wrapping, can be activated with `compact_definition_lists`: see
2546+[Non-pandoc extensions], below.)

2550+### Numbered example lists ###
32432551
3244−Many Markdown implementations do not require a space between the
3245−opening `#`s of an ATX heading and the heading text, so that
3246−`#5 bolt` and `#hashtag` count as headings. With this extension,
3247−pandoc does require the space.
2552+#### Extension: `example_lists` ####
32482553
3249−### Heading identifiers ###
2554+The special list marker `@` can be used for sequentially numbered
2555+examples. The first list item with a `@` marker will be numbered '1',
2556+the next '2', and so on, throughout the document. The numbered examples
2557+need not occur in a single list; each new list using `@` will take up
2558+where the last stopped. So, for example:
32502559
3251−See also the [`auto_identifiers`
3252−extension](#extension-auto_identifiers) above.
2560+ (@) My first example will be numbered (1).

32532562
3254−#### Extension: `header_attributes` ####
2563+ Explanation of examples.
32552564
3256−Headings can be assigned attributes using this syntax at the end
3257−of the line containing the heading text:
2565+ (@) My third example will be numbered (3).
32582566
3259− {#identifier .class .class key=value key=value}
2567+Numbered examples can be labeled and referred to elsewhere in the
2568+document:
32602569
3261−Thus, for example, the following headings will all be assigned the identifier
3262−`foo`:
2570+ (@good) This is a good example.
32632571
3264− # My heading {#foo}
2572+ As (@good) illustrates, ...
32652573
3266− ## My heading ## {#foo}
2574+The label can be any string of alphanumeric characters, underscores,
2575+or hyphens.
32672576
3268− My other heading {#foo}
3269− ---------------
2577+Note: continuation paragraphs in example lists must always
2578+be indented four spaces, regardless of the length of the
2579+list marker. That is, example lists always behave as if the
2580+`four_space_rule` extension is set. This is because example
2581+labels tend to be long, and indenting content to the
2582+first non-space character after the label would be awkward.
32702583
3271−(This syntax is compatible with [PHP Markdown Extra].)
2584+### Compact and loose lists ###
32722585
3273−Note that although this syntax allows assignment of classes and key/value
3274−attributes, writers generally don't use all of this information. Identifiers,
3275−classes, and key/value attributes are used in HTML and HTML-based formats such
3276−as EPUB and slidy. Identifiers are used for labels and link anchors in the
3277−LaTeX, ConTeXt, Textile, Jira markup, and AsciiDoc writers.
2586+Pandoc behaves differently from `Markdown.pl` on some "edge
2587+cases" involving lists. Consider this source:
32782588
3279−Headings with the class `unnumbered` will not be numbered, even if
3280−`--number-sections` is specified. A single hyphen (`-`) in an attribute
3281−context is equivalent to `.unnumbered`, and preferable in non-English
3282−documents. So,
2589+ + First
2590+ + Second:
2591+ - Fee
2592+ - Fie
2593+ - Foe
32832594
3284− # My heading {-}
2595+ + Third
32852596
3286−is just the same as
2597+Pandoc transforms this into a "compact list" (with no `<p>` tags around
2598+"First", "Second", or "Third"), while Markdown puts `<p>` tags around
2599+"Second" and "Third" (but not "First"), because of the blank space
2600+around "Third". Pandoc follows a simple rule: if the text is followed by
2601+a blank line, it is treated as a paragraph. Since "Second" is followed
2602+by a list, and not a blank line, it isn't treated as a paragraph. The
2603+fact that the list is followed by a blank line is irrelevant. (Note:
2604+Pandoc works this way even when the `markdown_strict` format is specified. This
2605+behavior is consistent with the official Markdown syntax description,
2606+even though it is different from that of `Markdown.pl`.)

3340−and an optional space. (The `>` need not start at the left margin, but

3527−### Bullet lists ###
3528−
3529−A bullet list is a list of bulleted list items. A bulleted list
3530−item begins with a bullet (`*`, `+`, or `-`). Here is a simple
3531−example:
3532−
3533− * one
3534− * two
3535− * three
3536−
3537−This will produce a "compact" list. If you want a "loose" list, in which
3538−each item is formatted as a paragraph, put spaces between the items:
3539−
3540− * one
3541−
3542− * two
3543−
3544− * three
3545−
3546−The bullets need not be flush with the left margin; they may be
3547−indented one, two, or three spaces. The bullet must be followed
3548−by whitespace.
3549−
3550−List items look best if subsequent lines are flush with the first
3551−line (after the bullet):
3552−
3553− * here is my first
3554− list item.
3555− * and my second.
3556−
3557−But Markdown also allows a "lazy" format:
3558−
3559− * here is my first
3560− list item.
3561− * and my second.
3562−
3563−### Block content in list items ###
3564−
3565−A list item may contain multiple paragraphs and other block-level
3566−content. However, subsequent paragraphs must be preceded by a blank line
3567−and indented to line up with the first non-space content after
3568−the list marker.
3569−
3570− * First paragraph.
3571−
3572− Continued.
3573−
3574− * Second paragraph. With a code block, which must be indented
3575− eight spaces:
3576−
3577− { code }
3578−
3579−Exception: if the list marker is followed by an indented code
3580−block, which must begin 5 spaces after the list marker, then
3581−subsequent paragraphs must begin two columns after the last
3582−character of the list marker:
3583−
3584− * code
3585−
3586− continuation paragraph
3587−
3588−List items may include other lists. In this case the preceding blank
3589−line is optional. The nested list must be indented to line up with
3590−the first non-space character after the list marker of the
3591−containing list item.
3592−
3593− * fruits
3594− + apples

3596− - red delicious
3597− + pears
3598− + peaches
3599− * vegetables
3600− + broccoli
3601− + chard
3602−
3603−As noted above, Markdown allows you to write list items "lazily," instead of
3604−indenting continuation lines. However, if there are multiple paragraphs or
3605−other blocks in a list item, the first line of each must be indented.
3606−
3607− + A lazy, lazy, list

3617−
3618−Ordered lists work just like bulleted lists, except that the items
3619−begin with enumerators rather than bullets.
3620−
3621−In standard Markdown, enumerators are decimal numbers followed
3622−by a period and a space. The numbers themselves are ignored, so
3623−there is no difference between this list:

3635−#### Extension: `fancy_lists` ####
3636−
3637−Unlike standard Markdown, pandoc allows ordered list items to be marked
3638−with uppercase and lowercase letters and roman numerals, in addition to
3639−Arabic numerals. List markers may be enclosed in parentheses or followed by a
3640−single right-parentheses or period. They must be separated from the
3641−text that follows by at least one space, and, if the list marker is a
3642−capital letter with a period, by at least two spaces.[^2]
3643−
3644−[^2]: The point of this rule is to ensure that normal paragraphs
3645− starting with people's initials, like
3646−
3647− B. Russell was an English philosopher.

3663− #. one
3664− #. two
3665−
3666−#### Extension: `startnum` ####
3667−
3668−Pandoc also pays attention to the type of list marker used, and to the
3669−starting number, and both of these are preserved where possible in the
3670−output format. Thus, the following yields a list with numbers followed
3671−by a single parenthesis, starting with 9, and a sublist with lowercase
3672−roman numerals:
3673−
3674− 9) Ninth
3675− 10) Tenth
3676− 11) Eleventh
3677− i. subone
3678− ii. subtwo
3679− iii. subthree
3680−
3681−Pandoc will start a new list each time a different type of list
3682−marker is used. So, the following will create three lists:
3683−
3684− (2) Two
3685− (5) Three
3686− 1. Four

3720−
3721−Each term must fit on one line, which may optionally be followed by
3722−a blank line, and must be followed by one or more definitions.
3723−A definition begins with a colon or tilde, which may be indented one
3724−or two spaces.
3725−
3726−A term may have multiple definitions, and each definition may
3727−consist of one or more block elements (paragraph, code block,
3728−list, etc.), each indented four spaces or one tab stop. The
3729−body of the definition (including the first line, aside from the
3730−colon or tilde) should be indented four spaces. However, as with
3731−other Markdown lists, you can "lazily" omit indentation except
3732−at the beginning of a paragraph or other block element:
3733−
3734− Term 1
3735−
3736− : Definition
3737− with lazy continuation.
3738−
3739− Second paragraph of the definition.
3740−
3741−If you leave space before the definition (as in the example above),
3742−the text of the definition will be treated as a paragraph. In some
3743−output formats, this will mean greater spacing between term/definition
3744−pairs. For a more compact definition list, omit the space before the
3745−definition:
3746−
3747− Term 1
3748− ~ Definition 1
3749−
3750− Term 2

3763−
3764−#### Extension: `example_lists` ####
3765−
3766−The special list marker `@` can be used for sequentially numbered
3767−examples. The first list item with a `@` marker will be numbered '1',
3768−the next '2', and so on, throughout the document. The numbered examples
3769−need not occur in a single list; each new list using `@` will take up
3770−where the last stopped. So, for example:

3788−
3789−Note: continuation paragraphs in example lists must always
3790−be indented four spaces, regardless of the length of the
3791−list marker. That is, example lists always behave as if the
3792−`four_space_rule` extension is set. This is because example
3793−labels tend to be long, and indenting content to the
3794−first non-space character after the label would be awkward.

3809−
3810−To "cut off" the list after item two, you can insert some non-indented

3872−
3873− - If the dashed line is flush with the header text on the right side
3874− but extends beyond it on the left, the column is right-aligned.
3875− - If the dashed line is flush with the header text on the left side

3877− - If the dashed line extends beyond the header text on both sides,
3878− the column is centered.
3879− - If the dashed line is flush with the header text on both sides,
3880− the default alignment is used (in most cases, this will be left).
3881−

3883− [Markdown discussion list](http://six.pairlist.net/pipermail/markdown-discuss/2005-March/001097.html).
3884−
3885−The table must end with a blank line, or a line of dashes followed by
3886−a blank line.
3887−

3895− ------- ------ ---------- -------
3896−
3897−When the header row is omitted, column alignments are determined on the basis

3899−would be right, left, center, and right aligned, respectively.
3900−
3901−#### Extension: `multiline_tables` ####
3902−
3903−Multiline tables allow header and table rows to span multiple lines
3904−of text (but cells that span multiple columns or rows of the table are

4015−The syntax is identical to [PHP Markdown Extra tables]. The beginning and
4016−ending pipe characters are optional, but pipes are required between all
4017−columns. The colons indicate column alignment as shown. The header
4018−cannot be omitted. To simulate a headerless table, include a header
4019−with blank cells.
4020−
4021−Since the pipes indicate column boundaries, columns need not be vertically
4022−aligned, as they are in the above example. So, this is a perfectly
4023−legal (though ugly) pipe table:

4027− apple|2.05
4028− pear|1.37
4029− orange|3.09
4030−
4031−The cells of pipe tables cannot contain block elements like paragraphs
4032−and lists, and cannot span multiple lines. If a pipe table contains a
4033−row whose Markdown content is wider than the column width (see
4034−`--columns`), then the table will take up the full text width and
4035−the cell contents will wrap, with the relative cell widths determined
4036−by the number of dashes in the line separating the table header from
4037−the table body. (For example `---|-` would make the first column 3/4
4038−and the second column 1/4 of the full text width.)
4039−On the other hand, if no lines are wider than column width, then
4040−cell contents will not be wrapped, and the cells will be sized

4067−it will be parsed as bibliographic information, not regular text. (It
4068−will be used, for example, in the title of standalone LaTeX or HTML
4069−output.) The block may contain just a title, a title and an author,
4070−or all three elements. If you want to include an author but no
4071−title, or a title and a date but no author, you need a blank line:

4083−
4084−The title may occupy multiple lines, but continuation lines must

4091−
4092−If a document has multiple authors, the authors may be put on

4112−All three metadata fields may contain standard inline formatting
4113−(italics, links, footnotes, etc.).
4114−
4115−Title blocks will always be parsed, but they will affect the output only
4116−when the `--standalone` (`-s`) option is chosen. In HTML output, titles
4117−will appear twice: once in the document head -- this is the title that
4118−will appear at the top of the window in a browser -- and once at the
4119−beginning of the document body. The title in the document head can have
4120−an optional prefix attached (`--title-prefix` or `-T` option). The title
4121−in the body appears as an H1 element with class "title", so it can be
4122−suppressed or reformatted with CSS. If a title prefix is specified with
4123−`-T` and no title block appears in the document, the title prefix will
4124−be used by itself as the HTML title.
4125−
4126−The man page writer extracts a title, man page section number, and
4127−other header and footer information from the title line. The title
4128−is assumed to be the first word on the title line, which may optionally
4129−end with a (single-digit) section number in parentheses. (There should
4130−be no space between the title and the parentheses.) Anything after
4131−this is assumed to be additional footer and header text. A single pipe
4132−character (`|`) should be used to separate the footer text from the header
4133−text. Thus,
4134−
4135− % PANDOC(1)
4136−
4137−will yield a man page with the title `PANDOC` and section 1.

4147−#### Extension: `yaml_metadata_block` ####
4148−
4149−A [YAML] metadata block is a valid YAML object, delimited by a line of three
4150−hyphens (`---`) at the top and a line of three hyphens (`---`) or three dots
4151−(`...`) at the bottom. A YAML metadata block may occur anywhere in the
4152−document, but if it is not at the beginning, it must be preceded by a blank
4153−line. (Note that, because of the way pandoc concatenates input files when
4154−several are provided, you may also keep the metadata in a separate YAML file
4155−and pass it to pandoc as an argument, along with your Markdown files:
4156−
4157− pandoc chap1.md chap2.md chap3.md metadata.yaml -s -o book.html
4158−
4159−Just be sure that the YAML file begins with `---` and ends with `---` or
4160−`...`.) Alternatively, you can use the `--metadata-file` option. Using
4161−that approach however, you cannot reference content (like footnotes)
4162−from the main markdown input document.
4163−
4164−Metadata will be taken from the fields of the YAML object and added to any
4165−existing document metadata. Metadata can contain lists and objects (nested
4166−arbitrarily), but all string scalars will be interpreted as Markdown. Fields
4167−with names ending in an underscore will be ignored by pandoc. (They may be
4168−given a role by external processors.) Field names must not be
4169−interpretable as YAML numbers or boolean values (so, for
4170−example, `yes`, `True`, and `15` cannot be used as field names).
4171−
4172−A document may contain multiple metadata blocks. If two
4173−metadata blocks attempt to set the same field, the value from
4174−the second block will be taken.
4175−
4176−When pandoc is used with `-t markdown` to create a Markdown document,
4177−a YAML metadata block will be produced only if the `-s/--standalone`
4178−option is used. All of the metadata will appear in a single block
4179−at the beginning of the document.
4180−
4181−Note that [YAML] escaping rules must be followed. Thus, for example,
4182−if a title contains a colon, it must be quoted, and if it contains a
4183−backslash escape, then it must be ensured that it is not treated as a
4184−[YAML escape sequence]. The pipe character (`|`) can be used to begin
4185−an indented block that will be interpreted literally, without need for
4186−escaping. This form is necessary when the field contains blank lines
4187−or block-level formatting:
4188−
4189− ---
4190− title: 'This is the title: it contains a colon'
4191− author:
4192− - Author One
4193− - Author Two
4194− keywords: [nothing, nothingness]
4195− abstract: |
4196− This is the abstract.
4197−
4198− It consists of two paragraphs.
4199− ...
4200−
4201−The literal block after the `|` must be indented relative to the
4202−line containing the `|`. If it is not, the YAML will be invalid
4203−and pandoc will not interpret it as metadata. For an overview
4204−of the complex rules governing YAML, see the [Wikipedia entry on
4205−YAML syntax].
4206−
4207−Template variables will be set automatically from the metadata. Thus, for
4208−example, in writing HTML, the variable `abstract` will be set to the HTML
4209−equivalent of the Markdown in the `abstract` field:
4210−
4211− <p>This is the abstract.</p>
4212− <p>It consists of two paragraphs.</p>
4213−
4214−Variables can contain arbitrary YAML structures, but the template must match
4215−this structure. The `author` variable in the default templates expects a
4216−simple list or string, but can be changed to support more complicated
4217−structures. The following combination, for example, would add an affiliation
4218−to the author if one is given:
4219−
4220− ---
4221− title: The document title
4222− author:
4223− - name: Author One
4224− affiliation: University of Somewhere
4225− - name: Author Two
4226− affiliation: University of Nowhere
4227− ...
4228−
4229−To use the structured authors in the example above, you would need a custom
4230−template:
4231−
4232− $for(author)$
4233− $if(author.name)$
4234− $author.name$$if(author.affiliation)$ ($author.affiliation$)$endif$
4235− $else$
4236− $author$
4237− $endif$
4238− $endfor$
4239−
4240−Raw content to include in the document's header may be specified
4241−using `header-includes`; however, it is important to mark up
4242−this content as raw code for a particular output format, using
4243−the [`raw_attribute` extension](#extension-raw_attribute)), or it
4244−will be interpreted as markdown. For example:
4245−
4246− header-includes:
4247− - |
4248− ```{=latex}
4249− \let\oldsection\section
4250− \renewcommand{\section}[1]{\clearpage\oldsection{#1}}
4251− ```
4252−
4253−Note: the `yaml_metadata_block` extension works with
4254−`commonmark` as well as `markdown` (and it is enabled by default
4255−in `gfm` and `commonmark_x`). However, in these formats the
4256−following restrictions apply:
4257−
4258−- The YAML metadata block must occur at the beginning of the
4259− document (and there can be only one). If multiple files are
4260− given as arguments to pandoc, only the first can be a YAML
4261− metadata block.
4262−
4263−- The leaf nodes of the YAML structure are parsed in isolation from
4264− each other and from the rest of the document. So, for
4265− example, you can't use a reference link in these contexts
4266− if the link definition is somewhere else in the document.

42882680
4289−This rule is easier to remember than standard Markdown's rule,
4290−which allows only the following characters to be backslash-escaped:
2681+ Table: Demonstration of simple table syntax.
42912682
4292− \`*_{}[]()>#+-.!
2683+The headers and table rows must each fit on one line. Column
2684+alignments are determined by the position of the header text relative
2685+to the dashed line below it:[^4]
42932686
4294−(However, if the `markdown_strict` format is used, the standard Markdown rule
4295−will be used.)
2687+ - If the dashed line is flush with the header text on the right side
2688+ but extends beyond it on the left, the column is right-aligned.
2689+ - If the dashed line is flush with the header text on the left side
2690+ but extends beyond it on the right, the column is left-aligned.
2691+ - If the dashed line extends beyond the header text on both sides,
2692+ the column is centered.
2693+ - If the dashed line is flush with the header text on both sides,
2694+ the default alignment is used (in most cases, this will be left).
42962695
4297−A backslash-escaped space is parsed as a nonbreaking space. In TeX output,
4298−it will appear as `~`. In HTML and XML output, it will appear as a
4299−literal unicode nonbreaking space character (note that it will thus
4300−actually look "invisible" in the generated HTML source; you can still
4301−use the `--ascii` command-line option to make it appear as an explicit
4302−entity).
2696+[^4]: This scheme is due to Michel Fortin, who proposed it on the
2697+ [Markdown discussion list](http://six.pairlist.net/pipermail/markdown-discuss/2005-March/001097.html).
43032698
4304−A backslash-escaped newline (i.e. a backslash occurring at the end of
4305−a line) is parsed as a hard line break. It will appear in TeX output as
4306−`\\` and in HTML as `<br />`. This is a nice alternative to
4307−Markdown's "invisible" way of indicating hard line breaks using
4308−two trailing spaces on a line.
2699+The table must end with a blank line, or a line of dashes followed by
2700+a blank line.
43092701
4310−Backslash escapes do not work in verbatim contexts.
2702+The column headers may be omitted, provided a dashed line is used
2703+to end the table. For example:

4314−### Emphasis ###
2711+When headers are omitted, column alignments are determined on the basis
2712+of the first line of the table body. So, in the tables above, the columns
2713+would be right, left, center, and right aligned, respectively.
43152714
4316−To *emphasize* some text, surround it with `*`s or `_`, like this:
2715+#### Extension: `multiline_tables` ####
43172716
4318− This text is _emphasized with underscores_, and this
4319− is *emphasized with asterisks*.
2717+Multiline tables allow headers and table rows to span multiple lines
2718+of text (but cells that span multiple columns or rows of the table are
2719+not supported). Here is an example:
43202720
4321−Double `*` or `_` produces **strong emphasis**:
2721+ -------------------------------------------------------------
2722+ Centered Default Right Left
2723+ Header Aligned Aligned Aligned
2724+ ----------- ------- --------------- -------------------------
2725+ First row 12.0 Example of a row that
2726+ spans multiple lines.
43222727
4323− This is **strong emphasis** and __with underscores__.
2728+ Second row 5.0 Here's another one. Note
2729+ the blank line between
2730+ rows.
2731+ -------------------------------------------------------------
43242732
4325−A `*` or `_` character surrounded by spaces, or backslash-escaped,
4326−will not trigger emphasis:
2733+ Table: Here's the caption. It, too, may span
2734+ multiple lines.
43272735
4328− This is * not emphasized *, and \*neither is this\*.
2736+These work like simple tables, but with the following differences:
43292737
4330−#### Extension: `intraword_underscores` ####
2738+ - They must begin with a row of dashes, before the header text
2739+ (unless the headers are omitted).
2740+ - They must end with a row of dashes, then a blank line.
2741+ - The rows must be separated by blank lines.
43312742
4332−Because `_` is sometimes used inside words and identifiers,
4333−pandoc does not interpret a `_` surrounded by alphanumeric
4334−characters as an emphasis marker. If you want to emphasize
4335−just part of a word, use `*`:
2743+In multiline tables, the table parser pays attention to the widths of
2744+the columns, and the writers try to reproduce these relative widths in
2745+the output. So, if you find that one of the columns is too narrow in the
2746+output, try widening it in the Markdown source.
43362747
4337− feas*ible*, not feas*able*.
2748+Headers may be omitted in multiline tables as well as simple tables:

43432760
4344−To strikeout a section of text with a horizontal line, begin and end it
4345−with `~~`. Thus, for example,
2761+It is possible for a multiline table to have just one row, but the row
2762+should be followed by a blank line (and then the row of dashes that ends
2763+the table), or the table may be interpreted as a simple table.

4356−text by `~` characters. Thus, for example,
2781+The row of `=`s separates the header from the table body, and can be
2782+omitted for a headerless table. The cells of grid tables may contain
2783+arbitrary block elements (multiple paragraphs, code blocks, lists,

4360−The text between `^...^` or `~...~` may not contain spaces or

4362−spaces, these spaces must be escaped with backslashes. (This is
4363−to prevent accidental superscripting and subscripting through
4364−the ordinary use of `~` and `^`, and also bad interactions with
4365−footnotes.) Thus, if you want the letter P with 'a cat' in
4366−subscripts, use `P~a\ cat~`, not `P~a cat~`.

2807+Pandoc does not support grid tables with row spans or column spans.
2808+This means that neither variable numbers of columns across rows nor
2809+variable numbers of rows across columns are supported by Pandoc.
2810+All grid tables must have the same number of columns in each row,
2811+and the same number of rows in each column. For example, the

4398−### Small caps ###
2836+Since the pipes indicate column boundaries, columns need not be vertically
2837+aligned, as they are in the above example. So, this is a perfectly

2846+The cells of pipe tables cannot contain block elements like paragraphs
2847+and lists, and cannot span multiple lines. If a pipe table contains a
2848+row whose printable content is wider than the column width (see
2849+`--columns`), then the cell contents will wrap, with the
2850+relative cell widths determined by the widths of the separator

4494−## Raw HTML
2951+A YAML metadata block is a valid YAML object, delimited by a line of three
2952+hyphens (`---`) at the top and a line of three hyphens (`---`) or three dots
2953+(`...`) at the bottom. A YAML metadata block may occur anywhere in the
2954+document, but if it is not at the beginning, it must be preceded by a blank
2955+line. (Note that, because of the way pandoc concatenates input files when
2956+several are provided, you may also keep the metadata in a separate YAML file
2957+and pass it to pandoc as an argument, along with your Markdown files:

4498−Markdown allows you to insert raw HTML (or DocBook) anywhere in a document
4499−(except verbatim contexts, where `<`, `>`, and `&` are interpreted
4500−literally). (Technically this is not an extension, since standard
4501−Markdown allows it, but it has been made an extension so that it can
4502−be disabled if desired.)
2961+Just be sure that the YAML file begins with `---` and ends with `---` or
2962+`...`.)
45032963
4504−The raw HTML is passed through unchanged in HTML, S5, Slidy, Slideous,
4505−DZSlides, EPUB, Markdown, CommonMark, Emacs Org mode, and Textile
4506−output, and suppressed in other formats.
2964+Metadata will be taken from the fields of the YAML object and added to any
2965+existing document metadata. Metadata can contain lists and objects (nested
2966+arbitrarily), but all string scalars will be interpreted as Markdown. Fields
2967+with names ending in an underscore will be ignored by pandoc. (They may be
2968+given a role by external processors.)
45072969
4508−For a more explicit way of including raw HTML in a Markdown
4509−document, see the [`raw_attribute` extension][Extension: `raw_attribute`].
2970+A document may contain multiple metadata blocks. The metadata fields will
2971+be combined through a *left-biased union*: if two metadata blocks attempt
2972+to set the same field, the value from the first block will be taken.
45102973
4511−In the CommonMark format, if `raw_html` is enabled, superscripts,
4512−subscripts, strikeouts and small capitals will be represented as HTML.
4513−Otherwise, plain-text fallbacks will be used. Note that even if
4514−`raw_html` is disabled, tables will be rendered with HTML syntax if
4515−they cannot use pipe syntax.
2974+When pandoc is used with `-t markdown` to create a Markdown document,
2975+a YAML metadata block will be produced only if the `-s/--standalone`
2976+option is used. All of the metadata will appear in a single block
2977+at the beginning of the document.
45162978
4517−#### Extension: `markdown_in_html_blocks` ####
2979+Note that YAML escaping rules must be followed. Thus, for example,
2980+if a title contains a colon, it must be quoted. The pipe character
2981+(`|`) can be used to begin an indented block that will be interpreted
2982+literally, without need for escaping. This form is necessary
2983+when the field contains blank lines or block-level formatting:
45182984
4519−Standard Markdown allows you to include HTML "blocks": blocks
4520−of HTML between balanced tags that are separated from the surrounding text
4521−with blank lines, and start and end at the left margin. Within
4522−these blocks, everything is interpreted as HTML, not Markdown;
4523−so (for example), `*` does not signify emphasis.

2992+ This is the abstract.
45242993
4525−Pandoc behaves this way when the `markdown_strict` format is used; but
4526−by default, pandoc interprets material between HTML block tags as Markdown.
4527−Thus, for example, pandoc will turn

4532− <td>[a link](https://google.com)</td>
4533− </tr>
4534− </table>
2997+Template variables will be set automatically from the metadata. Thus, for
2998+example, in writing HTML, the variable `abstract` will be set to the HTML
2999+equivalent of the Markdown in the `abstract` field:
45353000
4536−into
3001+ <p>This is the abstract.</p>

4541− <td><a href="https://google.com">a link</a></td>
4542− </tr>
4543− </table>
3004+Variables can contain arbitrary YAML structures, but the template must match
3005+this structure. The `author` variable in the default templates expects a
3006+simple list or string, but can be changed to support more complicated
3007+structures. The following combination, for example, would add an affiliation
3008+to the author if one is given:
45443009
4545−whereas `Markdown.pl` will preserve it as is.

3017+ ...
45463018
4547−There is one exception to this rule: text between `<script>`,
4548−`<style>`, and `<textarea>` tags is not interpreted as Markdown.
3019+To use the structured authors in the example above, you would need a custom
3020+template:
45493021
4550−This departure from standard Markdown should make it easier to mix
4551−Markdown with HTML block elements. For example, one can surround
4552−a block of Markdown text with `<div>` tags without preventing it
4553−from being interpreted as Markdown.

3058+A backslash-escaped space is parsed as a nonbreaking space. It will

45983061
4599−#### Extension: `raw_attribute` ####
3062+A backslash-escaped newline (i.e. a backslash occurring at the end of

3064+`\\` and in HTML as `<br />`. This is a nice alternative to
3065+Markdown's "invisible" way of indicating hard line breaks using
3066+two trailing spaces on a line.
46003067
4601−Inline spans and fenced code blocks with a special
4602−kind of attribute will be parsed as raw content with the
4603−designated format. For example, the following produces a raw

3077+ This text is _emphasized with underscores_, and this
3078+ is *emphasized with asterisks*.
46243079
4625−The format name should match the target format name (see
4626−`-t/--to`, above, for a list, or use `pandoc

3080+Double `*` or `_` produces **strong emphasis**:
46323081
4633−This extension presupposes that the relevant kind of
4634−inline code or fenced code block is enabled. Thus, for
4635−example, to use a raw attribute with a backtick code block,
4636−`backtick_code_blocks` must be enabled.
3082+ This is **strong emphasis** and __with underscores__.
46373083
4638−The raw attribute cannot be combined with regular attributes.
3084+A `*` or `_` character surrounded by spaces, or backslash-escaped,
3085+will not trigger emphasis:

46433090
4644−When this extension is enabled, pandoc will parse LaTeX
4645−macro definitions and apply the resulting macros to all LaTeX
4646−math and raw LaTeX. So, for example, the following will work in
4647−all output formats, not just LaTeX:
3091+Because `_` is sometimes used inside words and identifiers,
3092+pandoc does not interpret a `_` surrounded by alphanumeric
3093+characters as an emphasis marker. If you want to emphasize
3094+just part of a word, use `*`:
46483095
4649− \newcommand{\tuple}[1]{\langle #1 \rangle}

3099+### Strikeout ###
46563100
4657−When `latex_macros` is disabled, the raw LaTeX and math will
4658−not have macros applied. This is usually a better approach when
4659−you are targeting LaTeX or PDF.
3101+#### Extension: `strikeout` ####
3102+
3103+To strikeout a section of text with a horizontal line, begin and end it
3104+with `~~`. Thus, for example,
46603105
4661−Macro definitions in LaTeX will be passed through as raw LaTeX
4662−only if `latex_macros` is not enabled. Macro definitions in
4663−Markdown source (or other formats allowing `raw_tex`) will
4664−be passed through regardless of whether `latex_macros` is

4671−### Automatic links ###
3111+#### Extension: `superscript`, `subscript` ####
46723112
4673−If you enclose a URL or email address in pointy brackets, it
4674−will become a link:
3113+Superscripts may be written by surrounding the superscripted text by `^`
3114+characters; subscripts may be written by surrounding the subscripted
3115+text by `~` characters. Thus, for example,
46753116
4676− <https://google.com>
4677− <sam@green.eggs.ham>
3117+ H~2~O is a liquid. 2^10^ is 1024.
46783118
4679−### Inline links ###
3119+If the superscripted or subscripted text contains spaces, these spaces
3120+must be escaped with backslashes. (This is to prevent accidental
3121+superscripting and subscripting through the ordinary use of `~` and `^`.)
3122+Thus, if you want the letter P with 'a cat' in subscripts, use

3242+Markdown allows you to insert raw HTML (or DocBook) anywhere in a document

4799−If you just want a regular inline image, just make sure it is not
4800−the only thing in the paragraph. One way to do this is to insert a

3248+The raw HTML is passed through unchanged in HTML, S5, Slidy, Slideous,

3254+Standard Markdown allows you to include HTML "blocks": blocks
3255+of HTML between balanced tags that are separated from the surrounding text

3430+### Inline links ###
50033431
5004−Pandoc uses some heuristics to separate the locator from the
5005−rest of the subject. It is sensitive to the locator terms
5006−defined in the [CSL locale files]. Either abbreviated or
5007−unabbreviated forms are accepted. In the `en-US` locale, locator
5008−terms can be written in either singular or plural forms, as
5009−`book`, `bk.`/`bks.`; `chapter`, `chap.`/`chaps.`; `column`,
5010−`col.`/`cols.`; `figure`, `fig.`/`figs.`; `folio`,

5015−`v.`/`vv.`; `volume`, `vol.`/`vols.`; `¶`/`¶¶`; `§`/`§§`. If no
5016−locator term is used, "page" is assumed.
3432+An inline link consists of the link text in square brackets,
3433+followed by the URL in parentheses. (Optionally, the URL can
3434+be followed by a link title, in quotes.)
50173435
5018−In complex cases, you can force something to be treated as
5019−a locator by enclosing it in curly braces or prevent parsing
5020−the suffix as locator by prepending curly braces:
3436+ This is an [inline link](/url), and here's [one with
3437+ a title](http://fsf.org "click here for a good time!").
50213438
5022− [@smith{ii, A, D-Z}, with a suffix]
5023− [@smith, {pp. iv, vi-xi, (xv)-(xvii)} with suffix here]
5024− [@smith{}, 99 years later]
3439+There can be no space between the bracketed part and the parenthesized part.
3440+The link text can contain formatting (such as emphasis), but the title cannot.
50253441
5026−A minus sign (`-`) before the `@` will suppress mention of
5027−the author in the citation. This can be useful when the
5028−author is already mentioned in the text:
3442+Email addresses in inline links are not autodetected, so they have to be
3443+prefixed with `mailto`:

5030− Smith says blah [-@smith04].
3445+ [Write me!](mailto:sam@green.eggs.ham)
50313446

5033−square brackets:
3447+### Reference links ###
50343448
5035− @smith04 says blah.
3449+An *explicit* reference link has two parts, the link itself and the link
3450+definition, which may occur elsewhere in the document (either
3451+before or after the link).
50363452
5037− @smith04 [p. 33] says blah.
3453+The link consists of link text in square brackets, followed by a label in
3454+square brackets. (There cannot be space between the two unless the
3455+`spaced_reference_links` extension is enabled.) The link definition
3456+consists of the bracketed label, followed by a colon and a space, followed by
3457+the URL, and optionally (after a space) a link title either in quotes or in
3458+parentheses. The label must not be parseable as a citation (assuming
3459+the `citations` extension is enabled): citations take precedence over
3460+link labels.

5043−When you are using a note style, it is usually better to let

5068−
5069−Rewrite relative paths for Markdown links and images, depending
5070−on the path of the file containing the link or image link. For
5071−each link or image, pandoc will compute the directory of the

5075−The use of this extension is best understood by example.
5076−Suppose you have a a subdirectory for each chapter of a book,

5102−used in [`header_attributes`][Extension: `header_attributes`].
5103−
5104−- Attributes that occur immediately after an inline
5105− element affect that element. If they follow a space, then they
5106− belong to the space. (Hence, this option subsumes
5107− `inline_code_attributes` and `link_attributes`.)
5108−- Attributes that occur immediately before a block
5109− element, on a line by themselves, affect that
5110− element.
5111−- Consecutive attribute specifiers may be used,
5112− either for blocks or for inlines. Their attributes
5113− will be combined.
5114−- Attributes that occur at the end of the text of
5115− a Setext or ATX heading (separated by whitespace
5116− from the text) affect the heading element. (Hence, this
5117− option subsumes `header_attributes`.)
5118−- Attributes that occur after the opening fence
5119− in a fenced code block affect the code block element. (Hence,
5120− this option subsumes `fenced_code_attributes`.)
5121−- Attributes that occur at the end of a reference

5174−Causes newlines within a paragraph to be ignored, rather than
5175−being treated as spaces or as hard line breaks, when they occur
5176−between two East Asian wide characters. This is a better choice

3521+ [Introduction]: #introduction
51853522
5186−Causes anything between `\(` and `\)` to be interpreted as inline
5187−TeX math, and anything between `\[` and `\]` to be interpreted
5188−as display TeX math. Note: a drawback of this extension is that
5189−it precludes escaping `(` and `[`.
3523+Internal links are currently supported for HTML formats (including
3524+HTML slide shows and EPUB), LaTeX, and ConTeXt.

5212− a field spanning multiple lines.
3540+An image with nonempty alt text, occurring by itself in a
3541+paragraph, will be rendered as a figure with a caption. The
3542+image's alt text will be used as the caption.
52133543
5214−See the MultiMarkdown documentation for details. If `pandoc_title_block` or
5215−`yaml_metadata_block` is enabled, it will take precedence over
5216−`mmd_title_block`.
3544+ 
52173545
5218−#### Extension: `abbreviations` ####
3546+How this is rendered depends on the output format. Some output
3547+formats (e.g. RTF) do not yet support figures. In those
3548+formats, you'll just get an image in a paragraph by itself, with
3549+no caption.
52193550
5220−Parses PHP Markdown Extra abbreviation keys, like
3551+If you just want a regular inline image, just make sure it is not

52233556
5224−Note that the pandoc document model does not support
5225−abbreviations, so if this extension is enabled, abbreviation keys are
5226−simply skipped (as opposed to being parsed as paragraphs).
3557+Note that in reveal.js slide shows, an image in a paragraph
3558+by itself that has the `stretch` class will fill the screen,
3559+and the caption and figure tags will be omitted.

3561+#### Extension: `link_attributes` ####
52293562
5230−Makes all absolute URIs into links, even when not surrounded by

5233−#### Extension: `mmd_link_attributes` ####
3565+ An inline {#id .class width=30 height=20px}
3566+ and a reference ![image][ref] with attributes.
52343567
5235−Parses multimarkdown style key-value attributes on link

5237−[`link_attributes`](#extension-link_attributes) extension.
3568+ [ref]: foo.jpg "optional title" {#id .class key=val key2="val 2"}
52383569
5239− This is a reference ![image][ref] with multimarkdown attributes.
3570+(This syntax is compatible with [PHP Markdown Extra] when only `#id`

5241− [ref]: https://path.to/image "Image title" width=20px height=30px
5242− id=myId class="myClass1 myClass2"
3573+For HTML and EPUB, all attributes except `width` and `height` (but
3574+including `srcset` and `sizes`) are passed through as is. The other
3575+writers ignore attributes that are not supported by their output
3576+format.
52433577
5244−#### Extension: `mmd_header_identifiers` ####
3578+The `width` and `height` attributes on images are treated specially. When
3579+used without a unit, the unit is assumed to be pixels. However, any of
3580+the following unit identifiers can be used: `px`, `cm`, `mm`, `in`, `inch`
3581+and `%`. There must not be any spaces between the number and the unit.
3582+For example:
52453583
5246−Parses multimarkdown style heading identifiers (in square brackets,
5247−after the heading but before any trailing `#`s in an ATX heading).
3584+```
3585+{ width=50% }
3586+```
52483587
5249−#### Extension: `compact_definition_lists` ####
3588+- Dimensions are converted to inches for output in page-based formats like
3589+ LaTeX. Dimensions are converted to pixels for output in HTML-like
3590+ formats. Use the `--dpi` option to specify the number of pixels per
3591+ inch. The default is 96dpi.
3592+- The `%` unit is generally relative to some available space.
3593+ For example the above example will render to
3594+ `<img href="file.jpg" style="width: 50%;" />` (HTML),
3595+ `\includegraphics[width=0.5\textwidth]{file.jpg}` (LaTeX), or
3596+ `\externalfigure[file.jpg][width=0.5\textwidth]` (ConTeXt).
3597+- Some output formats have a notion of a class
3598+ ([ConTeXt](http://wiki.contextgarden.net/Using_Graphics#Multiple_Image_Settings))
3599+ or a unique identifier (LaTeX `\caption`), or both (HTML).
3600+- When no `width` or `height` attributes are specified, the fallback
3601+ is to look at the image resolution and the dpi metadata embedded in
3602+ the image file.
52503603
5251−Activates the definition list syntax of pandoc 1.12.x and earlier.
5252−This syntax differs from the one described above under [Definition lists]
5253−in several respects:
3604+Spans
3605+-----
52543606
5255− - No blank line is required between consecutive items of the
5256− definition list.
5257− - To get a "tight" or "compact" list, omit space between consecutive
5258− items; the space between a term and its definition does not affect
5259− anything.
5260− - Lazy wrapping of paragraphs is not allowed: the entire definition must
5261− be indented four spaces.[^6]
3607+#### Extension: `bracketed_spans` ####
52623608
5263−[^6]: To see why laziness is incompatible with relaxing the requirement
5264− of a blank line between items, consider the following example:
3609+A bracketed sequence of inlines, as one would use to begin
3610+a link, will be treated as a span with attributes if it is
3611+followed immediately by attributes:
52653612
5266− bar
5267− : definition
5268− foo
5269− : definition
3613+ [This is *some text*]{.class key="val"}
52703614
5271− Is this a single list item with two definitions of "bar," the first of
5272− which is lazily wrapped, or two list items? To remove the ambiguity
5273− we must either disallow lazy wrapping or require a blank line between
5274− list items.

5279−all-caps for strong emphasis, surround by underscores
5280−for regular emphasis, add extra blank space around headings.
3620+Pandoc's Markdown allows footnotes, using the following syntax:

3755+(`pandoc-citeproc --bib2yaml` can produce these from a bibliography file in one
3756+of the supported formats.)
3757+
3758+Citations and references can be formatted using any style supported by the
3759+[Citation Style Language], listed in the [Zotero Style Repository].
3760+These files are specified using the `--csl` option or the `csl` metadata field.
3761+By default, `pandoc-citeproc` will use the [Chicago Manual of Style] author-date
3762+format. The CSL project provides further information on [finding and editing styles].
3763+
3764+To make your citations hyperlinks to the corresponding bibliography
3765+entries, add `link-citations: true` to your YAML metadata.
3766+
3767+Citations go inside square brackets and are separated by semicolons.
3768+Each citation must have a key, composed of '@' + the citation
3769+identifier from the database, and may optionally have a prefix,
3770+a locator, and a suffix. The citation key must begin with a letter, digit,
3771+or `_`, and may contain alphanumerics, `_`, and internal punctuation
3772+characters (`:.#$%&-+?<>~/`). Here are some examples:
3773+
3774+ Blah blah [see @doe99, pp. 33-35; also @smith04, chap. 1].
3775+
3776+ Blah blah [@doe99, pp. 33-35, 38-39 and *passim*].
3777+
3778+ Blah blah [@smith04; @doe99].
3779+
3780+`pandoc-citeproc` detects locator terms in the [CSL locale files].
3781+Either abbreviated or unabbreviated forms are accepted. In the `en-US`
3782+locale, locator terms can be written in either singular or plural forms,
3783+as `book`, `bk.`/`bks.`; `chapter`, `chap.`/`chaps.`; `column`,
3784+`col.`/`cols.`; `figure`, `fig.`/`figs.`; `folio`, `fol.`/`fols.`;
3785+`number`, `no.`/`nos.`; `line`, `l.`/`ll.`; `note`, `n.`/`nn.`; `opus`,
3786+`op.`/`opp.`; `page`, `p.`/`pp.`; `paragraph`, `para.`/`paras.`; `part`,
3787+`pt.`/`pts.`; `section`, `sec.`/`secs.`; `sub verbo`, `s.v.`/`s.vv.`;
3788+`verse`, `v.`/`vv.`; `volume`, `vol.`/`vols.`; `¶`/`¶¶`; `§`/`§§`. If no
3789+locator term is used, "page" is assumed.
3790+
3791+A minus sign (`-`) before the `@` will suppress mention of
3792+the author in the citation. This can be useful when the
3793+author is already mentioned in the text:
3794+
3795+ Smith says blah [-@smith04].
3796+
3797+You can also write an in-text citation, as follows:
3798+
3799+ @smith04 says blah.
3800+
3801+ @smith04 [p. 33] says blah.
3802+
3803+If the style calls for a list of works cited, it will be placed
3804+at the end of the document. Normally, you will want to end your
3805+document with an appropriate header:
3806+
3807+ last paragraph...
3808+
3809+ # References
54083810
5409−Note that `pandoc` can be used to produce such a YAML metadata
5410−section from a BibTeX, BibLaTeX, or CSL JSON bibliography:
3811+The bibliography will be inserted after this header. Note that
3812+the `unnumbered` class will be added to this header, so that the

6491− shelling out to the executable), it is possible to use it in a mode
6492− that fully isolates pandoc from your file system, by running the

6494− [Using the pandoc API](https://pandoc.org/using-the-pandoc-api.html)
6495− for more details.
6496−
6497−3. Pandoc's parsers can exhibit pathological performance on some
6498− corner cases. It is wise to put any pandoc operations under
6499− a timeout, to avoid DOS attacks that exploit these issues.
6500− If you are using the pandoc executable, you can add the
6501− command line options `+RTS -M512M -RTS` (for example) to limit

6504−4. The HTML generated by pandoc is not guaranteed to be safe.
6505− If `raw_html` is enabled for the Markdown input, users can
6506− inject arbitrary HTML. Even if `raw_html` is disabled,
