121+`.pdf` extension, as before, but add the `--pdf-engine` option
122+or `-t context`, `-t html`, or `-t ms` to the command line.
123+The tool used to generate the PDF from the intermediate format
124+may be specified using `--pdf-engine`.
125+
126+You can control the PDF style using variables, depending on
127+the intermediate format used: see [variables for LaTeX],
128+[variables for ConTeXt], [variables for `wkhtmltopdf`],
129+[variables for ms]. When HTML is used as an intermediate
130+format, the output can be styled using `--css`.
131+
132+To debug the PDF creation, it can be useful to look at the intermediate
133+representation: instead of `-o test.pdf`, use for example `-s -o test.tex`
134+to output the generated LaTeX. You can then test it with `pdflatex test.tex`.

144+[`setspace`] (with `linestretch`), and
145+[`babel`] (with `lang`). The use of `xelatex` or `lualatex` as
146+the PDF engine requires [`fontspec`]. `lualatex` uses
147+[`selnolig`]. `xelatex` uses [`polyglossia`] (with `lang`),
148+[`xecjk`], and [`bidi`] (with the `dir` variable set). If the
149+`mathspec` variable is set, `xelatex` will use [`mathspec`]
150+instead of [`unicode-math`]. The [`upquote`] and [`microtype`]
151+packages are used if available, and [`csquotes`] will be used
152+for [typography] if the `csquotes` variable or metadata field is
153+set to a true value. The [`natbib`], [`biblatex`], [`bibtex`],
154+and [`biber`] packages can optionally be used for [citation

1670+
1671+Fields that are omitted will just have their regular
1672+default values. So a defaults file can be as simple as
1673+one line:
1674+
1675+``` yaml
1676+verbosity: INFO
1677+```
1678+
1679+In fields that expect a file path (or list of file paths), the
1680+following syntax may be used to interpolate environment variables:
1681+
1682+``` yaml
1683+csl: ${HOME}/mycsldir/special.csl
1684+```
1685+
1686+`${USERDATA}` may also be used; this will always resolve to the
1687+user data directory that is current when the defaults file is
1688+parsed, regardless of the setting of the environment
1689+variable `USERDATA`.
1690+
1691+`${.}` will resolve to the directory containing the default
1692+file itself. This allows you to refer to resources contained
1693+in that directory:
1694+
1695+``` yaml
1696+epub-cover-image: ${.}/cover.jpg
1697+epub-metadata: ${.}/meta.xml
1698+resource-path:
1699+- . # the working directory from which pandoc is run
1700+- ${.}/images # the images subdirectory of the directory
1701+ # containing this defaults file
1702+```
1703+
1704+This environment variable interpolation syntax *only* works in
1705+fields that expect file paths.
1706+
1707+Default files can be placed in the `defaults` subdirectory of
1708+the user data directory and used from any directory. For
1709+example, one could create a file specifying defaults for writing
1710+letters, save it as `letter.yaml` in the `defaults` subdirectory
1711+of the user data directory, and then invoke these defaults
1712+from any directory using `pandoc --defaults letter`
1713+or `pandoc -dletter`.
1714+
1715+When multiple defaults are used, their contents will be combined.
1716+
1717+Note that, where command-line arguments may be repeated
1718+(`--metadata-file`, `--css`, `--include-in-header`,
1719+`--include-before-body`, `--include-after-body`, `--variable`,
1720+`--metadata`, `--syntax-definition`), the values specified on
1721+the command line will combine with values specified in the
1722+defaults file, rather than replacing them.

1751+using either [YAML metadata blocks][Extension: `yaml_metadata_block`]
1752+or with the `-M/--metadata` option. In addition, some variables
1753+are given default values by pandoc. See [Variables] below for
1754+a list of variables used in pandoc's default templates.

1070−Variables set by pandoc
1071−-----------------------
1756+If you use custom templates, you may need to revise them as pandoc
1757+changes. We recommend tracking the changes in the default templates,
1758+and modifying your custom templates accordingly. An easy way to do this
1759+is to fork the [pandoc-templates] repository and merge in
1760+changes after each pandoc release.
10721761

1182−Variables for slides
1183−--------------------
1864+### For loops
11841865
1185−Variables are available for [producing slide shows with pandoc],
1186−including all [reveal.js configuration options].
1866+A for loop begins with `for(variable)` (enclosed in
1867+matched delimiters) and ends with `endfor` (enclosed in matched
1868+delimiters.
11871869
1188−`slidy-url`
1189−: base URL for Slidy documents (defaults to
1190− `http://www.w3.org/Talks/Tools/Slidy2`)
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.
11911877
1192−`slideous-url`
1193−: base URL for Slideous documents (defaults to `slideous`)
1878+Examples:
11941879
1195−`s5-url`
1196−: base URL for S5 documents (defaults to `s5/default`)
1880+```
1881+$for(foo)$$foo$$sep$, $endfor$
11971882
1198−`revealjs-url`
1199−: base URL for reveal.js documents (defaults to `reveal.js`)
1883+$for(foo)$
1884+ - $foo.last$, $foo.first$
1885+$endfor$
12001886
1201−`theme`, `colortheme`, `fonttheme`, `innertheme`, `outertheme`
1202−: themes for LaTeX [`beamer`] documents
1887+${ for(foo.bar) }
1888+ - ${ foo.bar.last }, ${ foo.bar.first }
1889+${ endfor }
12031890
1204−`themeoptions`
1205−: options for LaTeX beamer themes (a list).
1891+$for(mymap)$
1892+$it.name$: $it.office$
1893+$endfor$
1894+```
12061895
1207−`navigation`
1208−: controls navigation symbols in `beamer` documents
1209− (default is `empty` for no navigation symbols; other valid values
1210− are `frame`, `vertical`, and `horizontal`).
1896+You may optionally specify a separator between consecutive
1897+values using `sep` (enclosed in matched delimiters). The
1898+material between `sep` and the `endfor` is the separator.
12111899
1212−`section-titles`
1213−: enables on "title pages" for new sections in `beamer`
1214− documents (default = true).
1900+```
1901+${ for(foo) }${ foo }${ sep }, ${ endfor }
1902+```
12151903
1216−`beamerarticle`
1217−: when true, the `beamerarticle` package is loaded (for
1218− producing an article from beamer slides).
1904+Instead of using `variable` inside the loop, the special
1905+anaphoric keyword `it` may be used.
12191906
1220−`colorlinks`
1221−: add color to link text; automatically enabled if any of `linkcolor`, `citecolor`,
1222− `urlcolor`, or `toccolor` are set (for beamer only).
1907+```
1908+${ for(foo.bar) }
1909+ - ${ it.last }, ${ it.first }
1910+${ endfor }
1911+```
12231912
1224−`linkcolor`, `citecolor`, `urlcolor`, `toccolor`
1225−: color for internal links, citation links, external links, and links in table
1226− of contents: uses any of the [predefined LaTeX colors] (for beamer only).
1913+### Partials
12271914
1228−[reveal.js configuration options]: https://github.com/hakimel/reveal.js#configuration
1915+Partials (subtemplates stored in different files) may be
1916+included by using the name of the partial, followed
1917+by `()`, for example:
12291918

1920+${ styles() }
1921+```
12321922
1233−LaTeX variables are used when [creating a PDF].
1923+Partials will be sought in the directory containing
1924+the main template. The file name will be assumed to
1925+have the same extension as the main template if it
1926+lacks an extension. When calling the partial, the
1927+full name including file extension can also be used:
12341928
1235−`papersize`
1236−: paper size, e.g. `letter`, `A4`
1929+```
1930+${ styles.html() }
1931+```
12371932
1238−`fontsize`
1239−: font size for body text (e.g. `10pt`, `12pt`)
1933+(If a partial is not found in the directory of the
1934+template and the template path is given as a relative
1935+path, it will also be sought in the `templates`
1936+subdirectory of the user data directory.)
12401937
1241−`documentclass`
1242−: document class, e.g. [`article`], [`report`], [`book`], [`memoir`]
1938+Partials may optionally be applied to variables using
1939+a colon:
12431940
1244−`classoption`
1245−: option for document class, e.g. `oneside`; may be repeated
1246− for multiple options
1941+```
1942+${ date:fancy() }
12471943
1248−`geometry`
1249−: option for [`geometry`] package, e.g. `margin=1in`;
1250− may be repeated for multiple options
1944+${ articles:bibentry() }
1945+```
12511946
1252−`margin-left`, `margin-right`, `margin-top`, `margin-bottom`

1254− overrides these)
1947+If `articles` is an array, this will iterate over its
1948+values, applying the partial `bibentry()` to each one. So the
1949+second example above is equivalent to
12551950
1256−`linestretch`

1258− package, e.g. `1.25`, `1.5`
1951+```

1953+${ it:bibentry() }
1954+${ endfor }
1955+```
12591956
1260−`fontfamily`
1261−: font package for use with `pdflatex`:
1262− [TeX Live] includes many options, documented in the [LaTeX Font Catalogue].
1263− The default is [Latin Modern][`lm`].
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`.
12641961
1265−`fontfamilyoptions`
1266−: options for package used as `fontfamily`: e.g. `osf,sc` with
1267− `fontfamily` set to [`mathpazo`] provides Palatino with old-style

1962+Final newlines are omitted from included partials.
12691963
1270−`mainfont`, `sansfont`, `monofont`, `mathfont`, `CJKmainfont`
1271−: font families for use with `xelatex` or
1272− `lualatex`: take the name of any system font, using the
1273− [`fontspec`] package. Note that if `CJKmainfont` is used,
1274− the [`xecjk`] package must be available.
1964+Partials may include other partials.
12751965
1276−`mainfontoptions`, `sansfontoptions`, `monofontoptions`, `mathfontoptions`, `CJKoptions`
1277−: options to use with `mainfont`, `sansfont`, `monofont`, `mathfont`,
1278− `CJKmainfont` in `xelatex` and `lualatex`. Allow for any choices
1279− available through [`fontspec`], such as the OpenType features
1280− `Numbers=OldStyle,Numbers=Proportional`. May be repeated for multiple options.
1966+A separator between values of an array may be specified

1970+```
1971+${months[, ]}$

1286−`microtypeoptions`
1287−: options to pass to the microtype package
1973+${articles:bibentry()[; ]$
1974+```
1975+
1976+The separator in this case is literal and (unlike with `sep`
1977+in an explicit `for` loop) cannot contain interpolated
1978+variables or other template directives.
1979+
1980+### Nesting
1981+
1982+To ensure that content is "nested," that is, subsequent lines
1983+indented, use the `^` directive:
1984+
1985+```
1986+$item.number$ $^$$item.description$ ($item.price$)
1987+```
1988+
1989+In this example, if `item.description` has multiple lines,
1990+they will all be indented to line up with the first line:
1991+
1992+```
1993+00123 A fine bottle of 18-year old
1994+ Oban whiskey. ($148)
1995+```
1996+
1997+To nest multiple lines to the same level, align them
1998+with the `^` directive in the template. For example:
1999+
2000+```
2001+$item.number$ $^$$item.description$ ($item.price$)
2002+ (Available til $item.sellby$.)
2003+```
2004+
2005+will produce
2006+
2007+```
2008+00123 A fine bottle of 18-year old
2009+ Oban whiskey. ($148)
2010+ (Available til March 30, 2020.)
2011+```
2012+
2013+If a variable occurs by itself on a line, preceded by whitespace
2014+and not followed by further text or directives on the same line,
2015+and the variable's value contains multiple lines, it will be
2016+nested automatically.
2017+
2018+### Breakable spaces
2019+
2020+Normally, spaces in the template itself (as opposed to values of
2021+the interpolated variables) are not breakable, but they can be
2022+made breakable in part of the template by using the `~` keyword
2023+(ended with another `~`).
2024+
2025+```
2026+$~$This long line may break if the document is rendered
2027+with a short line length.$~$
2028+```
2029+
2030+### Pipes
2031+
2032+A pipe transforms the value of a variable or partial. Pipes are
2033+specified using a slash (`/`) between the variable name (or partial)
2034+and the pipe name. Example:
2035+
2036+```
2037+$for(name)$
2038+$name/uppercase$
2039+$endfor$
2040+
2041+$for(metadata/pairs)$
2042+- $it.key$: $it.value$
2043+$endfor$
2044+
2045+$employee:name()/uppercase$
2046+```
2047+
2048+Pipes may be chained:
2049+
2050+```
2051+$for(employees/pairs)$
2052+$it.key/alpha/uppercase$. $it.name$
2053+$endfor$
2054+```
2055+
2056+Some pipes take parameters:
2057+
2058+```
2059+|----------------------|------------|
2060+$for(employee)$
2061+$it.name.first/uppercase/left 20 "| "$$it.name.salary/right 10 " | " " |"$
2062+$endfor$
2063+|----------------------|------------|
2064+```
2065+
2066+Currently the following pipes are predefined:
2067+
2068+- `pairs`: Converts a map or array to an array of maps,
2069+ each with `key` and `value` fields. If the original
2070+ value was an array, the `key` will be the array index,
2071+ starting with 1.
2072+
2073+- `uppercase`: Converts text to uppercase.
2074+
2075+- `lowercase`: Converts text to lowercase.
2076+
2077+- `length`: Returns the length of the value: number
2078+ of characters for a textual value, number of elements
2079+ for a map or array.
2080+
2081+- `reverse`: Reverses a textual value or array,
2082+ and has no effect on other values.
2083+
2084+- `first`: Returns the first value of an array, if
2085+ applied to a non-empty array; otherwise returns
2086+ the original value.
2087+
2088+- `last`: Returns the last value of an array, if
2089+ applied to a non-empty array; otherwise returns
2090+ the original value.
2091+
2092+- `rest`: Returns all but the first value of an array, if
2093+ applied to a non-empty array; otherwise returns
2094+ the original value.
2095+
2096+- `allbutlast`: Returns all but the last value of an array, if
2097+ applied to a non-empty array; otherwise returns
2098+ the original value.
2099+
2100+- `chomp`: Removes trailing newlines (and breakable space).
2101+
2102+- `nowrap`: Disables line wrapping on breakable spaces.
2103+
2104+- `alpha`: Converts textual values that can be
2105+ read as an integer into lowercase alphabetic
2106+ characters `a..z` (mod 26). This can be used to get lettered
2107+ enumeration from array indices. To get uppercase
2108+ letters, chain with `uppercase`.
2109+
2110+- `roman`: Converts textual values that can be
2111+ read as an integer into lowercase roman numerials.
2112+ This can be used to get lettered enumeration from array indices.
2113+ To get uppercase roman, chain with `uppercase`.
2114+
2115+- `left n "leftborder" "rightborder"`: Renders a textual value
2116+ in a block of width `n`, aligned to the left, with an optional
2117+ left and right border. Has no effect on other values. This
2118+ can be used to align material in tables. Widths are positive
2119+ integers indicating the number of characters. Borders
2120+ are strings inside double quotes; literal `"` and `\` characters
2121+ must be backslash-escaped.
2122+
2123+- `right n "leftborder" "rightborder"`: Renders a textual value
2124+ in a block of width `n`, aligned to the right, and has no
2125+ effect on other values.
2126+
2127+- `center n "leftborder" "rightborder"`: Renders a textual
2128+ value in a block of width `n`, aligned to the center, and has
2129+ no effect on other values.
2130+
2131+
2132+## Variables
2133+
2134+### Metadata variables
2135+
2136+`title`, `author`, `date`
2137+: allow identification of basic aspects of the document. Included
2138+ in PDF metadata through LaTeX and ConTeXt. These can be set
2139+ through a [pandoc title block][Extension: `pandoc_title_block`],
2140+ which allows for multiple authors, or through a
2141+ [YAML metadata block][Extension: `yaml_metadata_block`]:
2142+
2143+ ---
2144+ author:
2145+ - Aristotle
2146+ - Peter Abelard
2147+ ...
2148+
2149+ Note that if you just want to set PDF or HTML metadata, without
2150+ including a title block in the document itself, you can
2151+ set the `title-meta`, `author-meta`, and `date-meta`
2152+ variables. (By default these are set automatically, based
2153+ on `title`, `author`, and `date`.) The page title in HTML
2154+ is set by `pagetitle`, which is equal to `title` by default.
2155+
2156+`subtitle`
2157+: document subtitle, included in HTML, EPUB, LaTeX, ConTeXt, and docx
2158+ documents
2159+
2160+`abstract`
2161+: document summary, included in LaTeX, ConTeXt, AsciiDoc, and docx
2162+ documents
2163+
2164+`keywords`
2165+: list of keywords to be included in HTML, PDF, ODT, pptx, docx
2166+ and AsciiDoc metadata; repeat as for `author`, above
2167+
2168+`subject`
2169+: document subject, included in ODT, PDF, docx and pptx metadata
2170+
2171+`description`
2172+: document description, included in ODT, docx and pptx metadata. Some
2173+ applications show this as `Comments` metadata.
2174+
2175+`category`
2176+: document category, included in docx and pptx metadata
2177+
2178+Additionally,
2179+any root-level string metadata, not included in ODT, docx
2180+or pptx metadata is added as a *custom property*.
2181+The following [YAML] metadata block for instance:
2182+
2183+ ---
2184+ title: 'This is the title'
2185+ subtitle: "This is the subtitle"
2186+ author:
2187+ - Author One
2188+ - Author Two
2189+ description: |
2190+ This is a long
2191+ description.
2192+
2193+ It consists of two paragraphs
2194+ ...
2195+
2196+will include `title`, `author` and `description` as standard document
2197+properties and `subtitle` as a custom property when converting to docx,
2198+ODT or pptx.
2199+
2200+### Language variables
2201+
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.
2208+
2209+ Use native pandoc [Divs and Spans] with the `lang` attribute to
2210+ switch the language:
2211+
2212+ ---
2213+ lang: en-GB
2214+ ...
2215+
2216+ Text in the main document language (British English).
2217+
2218+ ::: {lang=fr-CA}
2219+ > Cette citation est écrite en français canadien.
2220+ :::
2221+
2222+ More text in English. ['Zitat auf Deutsch.']{lang=de}
2223+
2224+`dir`
2225+: the base script direction, either `rtl` (right-to-left)
2226+ or `ltr` (left-to-right).
2227+
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].
2234+
2235+ When using LaTeX for bidirectional documents, only the
2236+ `xelatex` engine is fully supported (use
2237+ `--pdf-engine=xelatex`).

2243+### Variables for HTML
2244+
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`.
2252+
2253+`mainfont`
2254+: sets the CSS `font-family` property on the `html` element.
2255+
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).
2260+
2261+`fontcolor`
2262+: sets the CSS `color` property on the `html` element.
2263+
2264+`linkcolor`
2265+: sets the CSS `color` property on all links.
2266+
2267+`monofont`
2268+: sets the CSS `font-family` property on `code` elements.
2269+
2270+`monobackgroundcolor`
2271+: sets the CSS `background-color` property on `code` elements
2272+ and adds extra padding.
2273+
2274+`linestretch`
2275+: sets the CSS `line-height` property on the `html` element,
2276+ which is preferred to be unitless.
2277+
2278+`backgroundcolor`
2279+: sets the CSS `background-color` property on the `html` element.
2280+
2281+`margin-left`, `margin-right`, `margin-top`, `margin-bottom`
2282+: sets the corresponding CSS `padding` properties on the `body` element.
2283+
2284+To override or extend some [CSS] for just one document, include for example:
2285+
2286+ ---
2287+ header-includes: |
2288+ <style>
2289+ blockquote {
2290+ font-style: italic;

2293+ background-color: #f0f0f0;
2294+ }
2295+ td, th {
2296+ padding: 0.5em 2em 0.5em 0.5em;
2297+ }
2298+ tbody {
2299+ border-bottom: none;

2305+
2306+### Variables for HTML math
2307+
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`.
2312+
2313+### Variables for HTML slides
2314+

2384+
2385+`monofont`
2386+: font to use for code.
2387+
2388+### Variables for LaTeX
2389+
2390+Pandoc uses these variables when [creating a PDF] with a LaTeX engine.
2391+
2392+#### Layout
2393+
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:
2401+
2402+ ---
2403+ documentclass: scrartcl
2404+ header-includes: |
2405+ \RedeclareSectionCommand[
2406+ beforeskip=-10pt plus -2pt minus -1pt,
2407+ afterskip=1sp plus -1sp minus 1sp,
2408+ font=\normalfont\itshape]{paragraph}
2409+ \RedeclareSectionCommand[
2410+ beforeskip=-10pt plus -2pt minus -1pt,
2411+ afterskip=1sp plus -1sp minus 1sp,
2412+ font=\normalfont\scshape,
2413+ indent=0pt]{subparagraph}
2414+ ...
2415+
2416+`classoption`
2417+: option for document class, e.g. `oneside`; repeat for multiple options:
2418+
2419+ ---
2420+ classoption:
2421+ - twocolumn
2422+ - landscape
2423+ ...
2424+
2425+`documentclass`
2426+: document class: usually one of the standard classes,
2427+ [`article`], [`book`], and [`report`]; the [KOMA-Script]
2428+ equivalents, `scrartcl`, `scrbook`, and `scrreprt`, which
2429+ default to smaller margins; or [`memoir`]
2430+
2431+`geometry`
2432+: option for [`geometry`] package, e.g. `margin=1in`;
2433+ repeat for multiple options:
2434+
2435+ ---
2436+ geometry:
2437+ - top=30mm
2438+ - left=20mm
2439+ - heightrounded
2440+ ...
2441+
2442+`hyperrefoptions`
2443+: option for [`hyperref`] package, e.g. `linktoc=all`;
2444+ repeat for multiple options:
2445+
2446+ ---
2447+ hyperrefoptions:
2448+ - linktoc=all
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)
2457+
2458+`linestretch`
2459+: adjusts line spacing using the [`setspace`]
2460+ package, e.g. `1.25`, `1.5`
2461+
2462+`margin-left`, `margin-right`, `margin-top`, `margin-bottom`
2463+: sets margins if `geometry` is not used (otherwise `geometry`
2464+ overrides these)
2465+
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)
2470+
2471+`papersize`
2472+: paper size, e.g. `letter`, `a4`
2473+
2474+`secnumdepth`
2475+: numbering depth for sections (with `--number-sections` option
2476+ or `numbersections` variable)

2482+ `pdflatex`); default is `T1` (see [LaTeX font encodings guide])
2483+
2484+`fontfamily`

2486+ [TeX Live] includes many options, documented in the [LaTeX Font Catalogue].
2487+ The default is [Latin Modern][`lm`].
2488+
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:
2493+
2494+ ---
2495+ fontfamily: libertinus
2496+ fontfamilyoptions:
2497+ - osf
2498+ - p
2499+ ...
2500+
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`.
2505+
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.
2510+
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:
2517+
2518+ ---
2519+ mainfont: TeX Gyre Pagella
2520+ mainfontoptions:
2521+ - Numbers=Lowercase
2522+ - Numbers=Proportional
2523+ ...
2524+
2525+`microtypeoptions`
2526+: options to pass to the microtype package
2527+
2528+#### Links
2529+
2530+`colorlinks`
2531+: add color to link text; automatically enabled if any of
2532+ `linkcolor`, `filecolor`, `citecolor`, `urlcolor`, or `toccolor` are set
2533+
2534+`linkcolor`, `filecolor`, `citecolor`, `urlcolor`, `toccolor`
2535+: color for internal links, external links, citation links, linked
2536+ URLs, and links in table of contents, respectively: uses options
2537+ allowed by [`xcolor`], including the `dvipsnames`, `svgnames`, and
2538+ `x11names` lists
2539+
2540+`links-as-notes`
2541+: causes links to be printed as footnotes

2554+
2555+`toc-depth`
2556+: level of section to include in table of contents
2557+
2558+#### BibLaTeX Bibliographies

2587+### Variables for ConTeXt
2588+
2589+Pandoc uses these variables when [creating a PDF] with ConTeXt.
2590+
2591+`fontsize`
2592+: font size for body text (e.g. `10pt`, `12pt`)
2593+
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
2597+
2598+`indenting`
2599+: controls indentation of paragraphs, e.g. `yes,small,next` (see
2600+ [ConTeXt Indentation]); repeat for multiple options
2601+
2602+`interlinespace`
2603+: adjusts line spacing, e.g. `4ex` (using [`setupinterlinespace`]);
2604+ repeat for multiple options

2623+ [ConTeXt Font Switching])
2624+
2625+`margin-left`, `margin-right`, `margin-top`, `margin-bottom`

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

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

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)`

2665+ `--toc/--table-of-contents`)
2666+
2667+`whitespace`

2728+
2729+`pointsize`
2730+: point size (e.g. `10p`)
2731+
2732+### Variables set automatically
2733+
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:
2737+
2738+`body`
2739+: body of document
2740+
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`).
2750+

2753+ values)
2754+
2755+`include-before`
2756+: contents specified by `-B/--include-before-body` (may have
2757+ multiple values)
2758+

2760+: contents specified by `-A/--include-after-body` (may have
2761+ multiple values)
2762+
2763+`meta-json`
2764+: JSON representation of all of the document's metadata. Field
2765+ values are transformed to the selected output format.
2766+

2769+
2770+`sourcefile`, `outputfile`
2771+: source and destination filenames, as given on the command line.
2772+ `sourcefile` can also be a list if input comes from multiple files,
2773+ or empty if input is from stdin. You can use the following snippet in
2774+ your template to distinguish them:
2775+
2776+ $if(sourcefile)$
2777+ $for(sourcefile)$
2778+ $sourcefile$
2779+ $endfor$
2780+ $else$
2781+ (stdin)
2782+ $endif$
2783+
2784+ Similarly, `outputfile` can be `-` if output goes to the terminal.
2785+
2786+ If you need absolute paths, use e.g. `$curdir$/$sourcefile$`.
2787+
2788+`curdir`
2789+: working directory from which pandoc is run.
2790+
2791+`toc`

2799+
2800+# Extensions
2801+
2802+The behavior of some of the readers and writers can be adjusted by
2803+enabling or disabling various extensions.
2804+
2805+An extension can be enabled by adding `+EXTENSION`
2806+to the format name and disabled by adding `-EXTENSION`. For example,
2807+`--from markdown_strict+footnotes` is strict Markdown with footnotes
2808+enabled, while `--from markdown-footnotes-pipe_tables` is pandoc's
2809+Markdown without footnotes or pipe tables.
2810+
2811+The markdown reader and writer make by far the most use of extensions.
2812+Extensions only used by them are therefore covered in the
2813+section [Pandoc's Markdown] below (See [Markdown variants] for
2814+`commonmark` and `gfm`.) In the following, extensions that also work
2815+for other formats are covered.
2816+
2817+Note that markdown extensions added to the `ipynb` format
2818+affect Markdown cells in Jupyter notebooks (as do command-line
2819+options like `--atx-headers`).
2820+
2821+## Typography
2822+
2823+#### Extension: `smart` ####
2824+
2825+Interpret straight quotes as curly quotes, `---` as em-dashes,
2826+`--` as en-dashes, and `...` as ellipses. Nonbreaking spaces are
2827+inserted after certain abbreviations, such as "Mr."
2828+
2829+This extension can be enabled/disabled for the following formats:
2830+
2831+input formats
2832+: `markdown`, `commonmark`, `latex`, `mediawiki`, `org`, `rst`, `twiki`
2833+
2834+output formats
2835+: `markdown`, `latex`, `context`, `rst`
2836+
2837+enabled by default in
2838+: `markdown`, `latex`, `context` (both input and output)
2839+
2840+Note: If you are *writing* Markdown, then the `smart` extension
2841+has the reverse effect: what would have been curly quotes comes
2842+out straight.
2843+
2844+In LaTeX, `smart` means to use the standard TeX ligatures
2845+for quotation marks (` `` ` and ` '' ` for double quotes,
2846+`` ` `` and `` ' `` for single quotes) and dashes (`--` for
2847+en-dash and `---` for em-dash). If `smart` is disabled,
2848+then in reading LaTeX pandoc will parse these characters
2849+literally. In writing LaTeX, enabling `smart` tells pandoc
2850+to use the ligatures when possible; if `smart` is disabled
2851+pandoc will use unicode quotation mark and dash characters.
2852+
2853+## Headings and sections
2854+
2855+#### Extension: `auto_identifiers` ####
2856+
2857+A heading without an explicitly specified identifier will be
2858+automatically assigned a unique identifier based on the heading text.
2859+
2860+This extension can be enabled/disabled for the following formats:
2861+
2862+input formats
2863+: `markdown`, `latex`, `rst`, `mediawiki`, `textile`
2864+
2865+output formats
2866+: `markdown`, `muse`
2867+
2868+enabled by default in
2869+: `markdown`, `muse`
12882870
1289−`colorlinks`
1290−: add color to link text; automatically enabled if any of `linkcolor`, `citecolor`,
1291− `urlcolor`, or `toccolor` are set
2871+The default algorithm used to derive the identifier from the
2872+heading text is:
12922873
1293−`linkcolor`, `citecolor`, `urlcolor`, `toccolor`
1294−: color for internal links, citation links, external links, and links in table of contents:
1295− uses any of the [predefined LaTeX colors]
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).
2882+ - If nothing is left after this, use the identifier `section`.
12962883
1297−`links-as-notes`
1298−: causes links to be printed as footnotes
2884+Thus, for example,
12992885
1300−`indent`
1301−: uses document class settings for indentation (the default LaTeX template
1302− otherwise removes indentation and adds space between paragraphs)
2886+ Heading Identifier
2887+ ------------------------------- ----------------------------
2888+ `Heading identifiers in HTML` `heading-identifiers-in-html`
2889+ `Maître d'hôtel` `maître-dhôtel`
2890+ `*Dogs*?--in *my* house?` `dogs--in-my-house`
2891+ `[HTML], [S5], or [RTF]?` `html-s5-or-rtf`
2892+ `3. Applications` `applications`
2893+ `33` `section`
13032894
1304−`subparagraph`
1305−: disables default behavior of LaTeX template that redefines (sub)paragraphs
1306− as sections, changing the appearance of nested headings in some classes
2895+These rules should, in most cases, allow one to determine the identifier
2896+from the heading text. The exception is when several headings have the
2897+same text; in this case, the first will get an identifier as described
2898+above; the second will get the same identifier with `-1` appended; the
2899+third with `-2`; and so on.
13072900
1308−`thanks`
1309−: specifies contents of acknowledgments footnote after document title.
2901+(However, a different algorithm is used if
2902+`gfm_auto_identifiers` is enabled; see below.)
13102903
1311−`toc`
1312−: include table of contents (can also be set using `--toc/--table-of-contents`)
2904+These identifiers are used to provide link targets in the table of
2905+contents generated by the `--toc|--table-of-contents` option. They
2906+also make it easy to provide links from one section of a document to
2907+another. A link to this section, for example, might look like this:
13132908
1314−`toc-depth`
1315−: level of section to include in table of contents
2909+ See the section on
2910+ [heading identifiers](#heading-identifiers-in-html-latex-and-context).
13162911
1317−`secnumdepth`
1318−: numbering depth for sections, if sections are numbered
2912+Note, however, that this method of providing links to sections works
2913+only in HTML, LaTeX, and ConTeXt formats.
13192914
1320−`lof`, `lot`
1321−: include list of figures, list of tables
2915+If the `--section-divs` option is specified, then each section will
2916+be wrapped in a `section` (or a `div`, if `html4` was specified),
2917+and the identifier will be attached to the enclosing `<section>`
2918+(or `<div>`) tag rather than the heading itself. This allows entire
2919+sections to be manipulated using JavaScript or treated differently in
2920+CSS.
13222921
1323−`bibliography`
1324−: bibliography to use for resolving references
2922+#### Extension: `ascii_identifiers` ####
13252923
1326−`biblio-style`
1327−: bibliography style, when used with `--natbib` and `--biblatex`.
2924+Causes the identifiers produced by `auto_identifiers` to be pure ASCII.
2925+Accents are stripped off of accented Latin letters, and non-Latin
2926+letters are omitted.
13282927
1329−`biblio-title`
1330−: bibliography title, when used with `--natbib` and `--biblatex`.
2928+#### Extension: `gfm_auto_identifiers` ####
13312929
1332−`biblatexoptions`
1333−: list of options for biblatex.
2930+Changes the algorithm used by `auto_identifiers` to conform to
2931+GitHub's method. Spaces are converted to dashes (`-`),
2932+uppercase characters to lowercase characters, and punctuation
2933+characters other than `-` and `_` are removed.
2934+Emojis are replaced by their names.

2949+their respective sections of [Pandoc's Markdown]:
13592950
1360−`fontsize`
1361−: font size for body text (e.g. `10pt`, `12pt`)
2951+- [`raw_html`](#extension-raw_html) allows HTML elements which
2952+ are not representable in pandoc's AST to be parsed as raw HTML.
2953+ By default, this is disabled for HTML input.
13622954

14092999
1410−`section`
1411−: section number in man pages
3000+If you append `+lhs` (or `+literate_haskell`) to one of the formats
3001+above, pandoc will treat the document as literate Haskell source.
3002+This means that
14123003
1413−`header`
1414−: header in man pages
3004+ - In Markdown input, "bird track" sections will be parsed as Haskell
3005+ code rather than block quotations. Text between `\begin{code}`
3006+ and `\end{code}` will also be treated as Haskell code. For
3007+ ATX-style headings the character '=' will be used instead of '#'.
14153008
1416−`footer`
1417−: footer in man pages
3009+ - In Markdown output, code blocks with classes `haskell` and `literate`
3010+ will be rendered using bird tracks, and block quotations will be
3011+ indented one space, so they will not be treated as Haskell code.
3012+ In addition, headings will be rendered setext-style (with underlines)
3013+ rather than ATX-style (with '#' characters). (This is because ghc
3014+ treats '#' characters in column 1 as introducing line numbers.)
14183015
1419−`adjusting`
1420−: adjusts text to left (`l`), right (`r`), center (`c`),
1421− or both (`b`) margins
3016+ - In restructured text input, "bird track" sections will be parsed
3017+ as Haskell code.
14223018
1423−`hyphenate`
1424−: if `true` (the default), hyphenation will be used

14253021
1426−Using variables in templates
1427−----------------------------
3022+ - In LaTeX input, text in `code` environments will be parsed as
3023+ Haskell code.
14283024
1429−Variable names are sequences of alphanumerics, `-`, and `_`,
1430−starting with a letter. A variable name surrounded by `$` signs
1431−will be replaced by its value. For example, the string `$title$` in
3025+ - In LaTeX output, code blocks with class `haskell` will be rendered
3026+ inside `code` environments.
14323027
1433− <title>$title$</title>
3028+ - In HTML output, code blocks with class `haskell` will be rendered
3029+ with class `literatehaskell` and bird tracks.
14343030
1435−will be replaced by the document title.
3031+Examples:
14363032
1437−To write a literal `$` in a template, use `$$`.
3033+ pandoc -f markdown+lhs -t html
14383034
1439−Templates may contain conditionals. The syntax is as follows:
3035+reads literate Haskell source formatted with Markdown conventions and writes
3036+ordinary HTML (without bird tracks).
14403037
1441− $if(variable)$
1442− X
1443− $else$
1444− Y
1445− $endif$
3038+ pandoc -f markdown+lhs -t html+lhs
14463039
1447−This will include `X` in the template if `variable` has a non-null
1448−value; otherwise it will include `Y`. `X` and `Y` are placeholders for
1449−any valid template text, and may include interpolated variables or other
1450−conditionals. The `$else$` section may be omitted.
3040+writes HTML with the Haskell code in bird tracks, so it can be copied
3041+and pasted as literate Haskell source.
14513042
1452−When variables can have multiple values (for example, `author` in
1453−a multi-author document), you can use the `$for$` keyword:
3043+Note that GHC expects the bird tracks in the first column, so indented
3044+literate code blocks (e.g. inside an itemized environment) will not be
3045+picked up by the Haskell compiler.
14543046
1455− $for(author)$
1456− <meta name="author" content="$author$" />
1457− $endfor$
3047+## Other extensions
14583048
1459−You can optionally specify a separator to be used between
1460−consecutive items:
3049+#### Extension: `empty_paragraphs` ####
14613050
1462− $for(author)$$author$$sep$, $endfor$
3051+Allows empty paragraphs. By default empty paragraphs are
3052+omitted.
14633053
1464−A dot can be used to select a field of a variable that takes
1465−an object as its value. So, for example:
3054+This extension can be enabled/disabled for the following formats:

3076+of the referenced item. The original link text is replaced once
3077+the generated document is refreshed. This extension can be combined
3078+with `xrefs_number` in which case numbers will appear before the

1478−=================
3089+#### Extension: `xrefs_number` ####
3090+
3091+Links to headings, figures and tables inside the document are
3092+substituted with cross-references that will use the number
3093+of the referenced item. The original link text is discarded.
3094+This extension can be combined with `xrefs_name` in which case
3095+the name or caption numbers will appear after the number.
3096+
3097+For the `xrefs_number` to be useful heading numbers must be enabled
3098+in the generated document, also table and figure captions must be enabled
3099+using for example the `native_numbering` extension.
3100+
3101+Numbers in cross-references are only visible in the final document once
3102+it has been refreshed.

3105+
3106+output formats
3107+: `odt`, `opendocument`
3108+
3109+#### Extension: `styles` #### {#ext-styles}
3110+
3111+When converting from docx, read all docx styles as divs (for
3112+paragraph styles) and spans (for character styles) regardless
3113+of whether pandoc understands the meaning of these styles.
3114+This can be used with [docx custom styles](#custom-styles).
3115+Disabled by default.
3116+
3117+input formats
3118+: `docx`
3119+
3120+#### Extension: `amuse` ####
3121+
3122+In the `muse` input format, this enables Text::Amuse
3123+extensions to Emacs Muse markup.
3124+
3125+#### Extension: `raw_markdown` ####
3126+
3127+In the `ipynb` input format, this causes Markdown cells
3128+to be included as raw Markdown blocks (allowing lossless
3129+round-tripping) rather than being parsed. Use this only
3130+when you are targeting `ipynb` or a markdown-based
3131+output format.
3132+
3133+#### Extension: `citations` {#org-citations}
3134+
3135+Some aspects of [Pandoc's Markdown citation syntax](#citations)
3136+are also accepted in `org` input.
3137+
3138+#### Extension: `element_citations` ####
3139+
3140+In the `jats` output formats, this causes reference items to
3141+be replaced with `<element-citation>` elements. These
3142+elements are not influenced by CSL styles, but all information
3143+on the item is included in tags.
3144+
3145+#### Extension: `ntb` ####
3146+
3147+In the `context` output format this enables the use of [Natural Tables
3148+(TABLE)](https://wiki.contextgarden.net/TABLE) instead of the default
3149+[Extreme Tables (xtables)](https://wiki.contextgarden.net/xtables).
3150+Natural tables allow more fine-grained global customization but come
3151+at a performance penalty compared to extreme tables.

4859+Using the `native_divs` and `native_spans` extensions

4865+#### Extension: `fenced_divs` ####
4866+
4867+Allow special fenced syntax for native `Div` blocks. A Div
4868+starts with a fence containing at least three consecutive
4869+colons plus some attributes. The attributes may optionally
4870+be followed by another string of consecutive colons.
4871+The attribute syntax is exactly as in fenced code blocks (see
4872+[Extension: `fenced_code_attributes`]). As with fenced
4873+code blocks, one can use either attributes in curly braces
4874+or a single unbraced word, which will be treated as a class
4875+name. The Div ends with another line containing a string of at
4876+least three consecutive colons. The fenced Div should be
4877+separated by blank lines from preceding and following blocks.

4879+Example:

4985+Unless a citation key start with a letter, digit, or `_`,
4986+and contains only alphanumerics and internal punctuation
4987+characters (`:.#$%&-+?<>~/`), it must be surrounded
4988+by curly braces, which are not considered part of the key.
4989+In `@Foo_bar.baz.`, the key is `Foo_bar.baz`. The final
4990+period is not *internal* punctuation, so it is not included in
4991+the key. In `@{Foo_bar.baz.}`, the key is `Foo_bar.baz.`, including
4992+the final period. The curly braces are recommended if you use URLs as
4993+keys: `[@{https://example.com/bib?name=foobar&date=2000}, p. 33]`.
4994+
4995+Citation items may optionally include a prefix, a locator, and
4996+a suffix. In
4997+
4998+ Blah blah [see @doe99, pp. 33-35 and *passim*; @smith04, chap. 1].
4999+
5000+The first item (`doe99`) has prefix `see `, locator `pp. 33-35`,
5001+and suffix `and *passim*`. The second item (`smith04`) has
5002+locator `chap. 1` and no prefix or suffix.
5003+
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`,
5011+`fol.`/`fols.`; `number`, `no.`/`nos.`; `line`, `l.`/`ll.`;
5012+`note`, `n.`/`nn.`; `opus`, `op.`/`opp.`; `page`, `p.`/`pp.`;
5013+`paragraph`, `para.`/`paras.`; `part`, `pt.`/`pts.`; `section`,
5014+`sec.`/`secs.`; `sub verbo`, `s.v.`/`s.vv.`; `verse`,
5015+`v.`/`vv.`; `volume`, `vol.`/`vols.`; `¶`/`¶¶`; `§`/`§§`. If no
5016+locator term is used, "page" is assumed.
5017+
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:
5021+
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]
5025+
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:
5029+
5030+ Smith says blah [-@smith04].
5031+
5032+You can also write an author-in-text citation, by omitting the
5033+square brackets:
5034+
5035+ @smith04 says blah.
5036+
5037+ @smith04 [p. 33] says blah.
5038+
5039+This will cause the author's name to be rendered, followed by
5040+the bibliographical details. Use this form when you want to
5041+make the citation the subject of a sentence.
5042+
5043+When you are using a note style, it is usually better to let
5044+citeproc create the footnotes from citations rather than writing
5045+an explicit note. If you do write an explicit note that
5046+contains a citation, note that normal citations will be put in
5047+parentheses, while author-in-text citations will not. For
5048+this reason, it is sometimes preferable to use the
5049+author-in-text style inside notes when using a note style.

5060+## Non-default extensions
5061+
5062+The following Markdown syntax extensions are not enabled by default
5063+in pandoc, but may be enabled by adding `+EXTENSION` to the format
5064+name, where `EXTENSION` is the name of the extension. Thus, for
5065+example, `markdown+hard_line_breaks` is Markdown with hard line breaks.
5066+
5067+#### Extension: `rebase_relative_paths` ####
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
5072+containing file, relative to the working directory, and prepend
5073+the resulting path to the link or image path.
5074+
5075+The use of this extension is best understood by example.
5076+Suppose you have a a subdirectory for each chapter of a book,
5077+`chap1`, `chap2`, `chap3`. Each contains a file `text.md` and a
5078+number of images used in the chapter. You would like to have
5079+`` in `chap1/text.md` refer to
5080+`chap1/spider.jpg` and `` in `chap2/text.md`
5081+refer to `chap2/spider.jpg`. To do this, use
5082+
5083+ pandoc chap*/*.md -f markdown+rebase_relative_paths
5084+
5085+Without this extension, you would have to use
5086+`` in `chap1/text.md` and
5087+`` in `chap2/text.md`. Links with
5088+relative paths will be rewritten in the same way as images.
5089+
5090+Absolute paths and URLs are not changed. Neither are empty
5091+paths or paths consisting entirely of a fragment, e.g., `#foo`.
5092+
5093+Note that relative paths in reference links and images will
5094+be rewritten relative to the file containing the link
5095+reference definition, not the file containing the reference link
5096+or image itself, if these differ.
5097+
5098+#### Extension: `attributes` ####
5099+
5100+Allows attributes to be attached to any inline or block-level
5101+element. The syntax for the attributes is the same as that
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
5122+ link definition affect links that refer to that
5123+ definition.
5124+
5125+Note that pandoc's AST does not currently allow attributes
5126+to be attached to arbitrary elements. Hence a Span or Div
5127+container will be added if needed.
5128+
5129+#### Extension: `old_dashes` ####
5130+
5131+Selects the pandoc <= 1.8.2.1 behavior for parsing smart dashes:
5132+`-` before a numeral is an en-dash, and `--` is an em-dash.
5133+This option only has an effect if `smart` is enabled. It is
5134+selected automatically for `textile` input.
5135+
5136+#### Extension: `angle_brackets_escapable` ####
5137+
5138+Allow `<` and `>` to be backslash-escaped, as they can be in
5139+GitHub flavored Markdown but not original Markdown. This is
5140+implied by pandoc's default `all_symbols_escapable`.
5141+
5142+#### Extension: `lists_without_preceding_blankline` ####
5143+
5144+Allow a list to occur right after a paragraph, with no intervening
5145+blank space.
5146+
5147+#### Extension: `four_space_rule` ####
5148+
5149+Selects the pandoc <= 2.0 behavior for parsing lists, so that
5150+four spaces indent are needed for list item continuation
5151+paragraphs.
5152+
5153+#### Extension: `spaced_reference_links` ####
5154+
5155+Allow whitespace between the two components of a reference link,
5156+for example,
5157+
5158+ [foo] [bar].
5159+
5160+#### Extension: `hard_line_breaks` ####
5161+
5162+Causes all newlines within a paragraph to be interpreted as hard line
5163+breaks instead of spaces.
5164+
5165+#### Extension: `ignore_line_breaks` ####
5166+
5167+Causes newlines within a paragraph to be ignored, rather than being
5168+treated as spaces or as hard line breaks. This option is intended for
5169+use with East Asian languages where spaces are not used between words,
5170+but text is divided into lines for readability.
5171+
5172+#### Extension: `east_asian_line_breaks` ####
5173+
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
5177+than `ignore_line_breaks` for texts that include a mix of East
5178+Asian wide characters and other characters.
5179+
5180+#### Extension: `emoji` ####
5181+
5182+Parses textual emojis like `:smile:` as Unicode emoticons.
5183+
5184+#### Extension: `tex_math_single_backslash` ####
5185+
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 `[`.
5190+
5191+#### Extension: `tex_math_double_backslash` ####
5192+
5193+Causes anything between `\\(` and `\\)` to be interpreted as inline
5194+TeX math, and anything between `\\[` and `\\]` to be interpreted
5195+as display TeX math.
5196+
5197+#### Extension: `markdown_attribute` ####
5198+
5199+By default, pandoc interprets material inside block-level tags as Markdown.
5200+This extension changes the behavior so that Markdown is only parsed
5201+inside block-level tags if the tags have the attribute `markdown=1`.
5202+
5203+#### Extension: `mmd_title_block` ####
5204+
5205+Enables a [MultiMarkdown] style title block at the top of
5206+the document, for example:
5207+
5208+ Title: My title
5209+ Author: John Doe
5210+ Date: September 1, 2008
5211+ Comment: This is a sample mmd title block, with
5212+ a field spanning multiple lines.
5213+
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`.
5217+
5218+#### Extension: `abbreviations` ####
5219+
5220+Parses PHP Markdown Extra abbreviation keys, like
5221+
5222+ *[HTML]: Hypertext Markup Language
5223+
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).
5227+
5228+#### Extension: `autolink_bare_uris` ####
5229+
5230+Makes all absolute URIs into links, even when not surrounded by
5231+pointy braces `<...>`.
5232+
5233+#### Extension: `mmd_link_attributes` ####
5234+
5235+Parses multimarkdown style key-value attributes on link
5236+and image references. This extension should not be confused with the
5237+[`link_attributes`](#extension-link_attributes) extension.
5238+
5239+ This is a reference ![image][ref] with multimarkdown attributes.
5240+
5241+ [ref]: https://path.to/image "Image title" width=20px height=30px
5242+ id=myId class="myClass1 myClass2"
5243+
5244+#### Extension: `mmd_header_identifiers` ####
5245+
5246+Parses multimarkdown style heading identifiers (in square brackets,
5247+after the heading but before any trailing `#`s in an ATX heading).
5248+
5249+#### Extension: `compact_definition_lists` ####
5250+
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:
5254+
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]
5262+
5263+[^6]: To see why laziness is incompatible with relaxing the requirement
5264+ of a blank line between items, consider the following example:
5265+
5266+ bar
5267+ : definition
5268+ foo
5269+ : definition
31995270
3200−Using an external filter, `pandoc-citeproc`, pandoc can automatically generate
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.
5275+
5276+#### Extension: `gutenberg` ####
5277+
5278+Use [Project Gutenberg] conventions for `plain` output:
5279+all-caps for strong emphasis, surround by underscores
5280+for regular emphasis, add extra blank space around headings.
5281+
5282+ [Project Gutenberg]: https://www.gutenberg.org
5283+
5284+#### Extension: `sourcepos` ####
5285+
5286+Include source position attributes when parsing `commonmark`.
5287+For elements that accept attributes, a `data-pos` attribute
5288+is added; other elements are placed in a surrounding
5289+Div or Span elemnet with a `data-pos` attribute.
5290+
5291+## Markdown variants
5292+
5293+In addition to pandoc's extended Markdown, the following Markdown
5294+variants are supported:
5295+
5296+- `markdown_phpextra` (PHP Markdown Extra)
5297+- `markdown_github` (deprecated GitHub-Flavored Markdown)
5298+- `markdown_mmd` (MultiMarkdown)
5299+- `markdown_strict` (Markdown.pl)
5300+- `commonmark` (CommonMark)
5301+- `gfm` (Github-Flavored Markdown)
5302+- `commonmark_x` (CommonMark with many pandoc extensions)
5303+
5304+To see which extensions are supported for a given format,
5305+and which are enabled by default, you can use the command
5306+
5307+ pandoc --list-extensions=FORMAT
5308+
5309+where `FORMAT` is replaced with the name of the format.
5310+
5311+Note that the list of extensions for `commonmark`,
5312+`gfm`, and `commonmark_x` are defined relative to default
5313+commonmark. So, for example, `backtick_code_blocks`
5314+does not appear as an extension, since it is enabled by
5315+default and cannot be disabled.
5316+
5317+# Citations
5318+
5319+When the `--citeproc` option is used, pandoc can automatically generate
32015320citations and a bibliography in a number of styles. Basic usage is

3390−The following Markdown syntax extensions are not enabled by default
3391−in pandoc, but may be enabled by adding `+EXTENSION` to the format

3393−example, `markdown+hard_line_breaks` is Markdown with hard line breaks.
5428+### Capitalization in titles
33945429
3395−#### Extension: `old_dashes` ####
5430+If you are using a bibtex or biblatex bibliography, then observe
5431+the following rules:
33965432
3397−Selects the pandoc <= 1.8.2.1 behavior for parsing smart dashes:
3398−`-` before a numeral is an en-dash, and `--` is an em-dash.
3399−This option only has an effect if `smart` is enabled. It is
3400−selected automatically for `textile` input.
5433+ - English titles should be in title case. Non-English titles should
5434+ be in sentence case, and the `langid` field in biblatex should be
5435+ set to the relevant language. (The following values are treated
5436+ as English: `american`, `british`, `canadian`, `english`,
5437+ `australian`, `newzealand`, `USenglish`, or `UKenglish`.)
34015438
3402−#### Extension: `angle_brackets_escapable` ####
5439+ - As is standard with bibtex/biblatex, proper names should be
5440+ protected with curly braces so that they won't be lowercased
5441+ in styles that call for sentence case. For example:
34035442
3404−Allow `<` and `>` to be backslash-escaped, as they can be in
3405−GitHub flavored Markdown but not original Markdown. This is
3406−implied by pandoc's default `all_symbols_escapable`.
5443+ title = {My Dinner with {Andre}}
34075444
3408−#### Extension: `lists_without_preceding_blankline` ####
5445+ - In addition, words that should remain lowercase (or camelCase)
5446+ should be protected:
34095447
3410−Allow a list to occur right after a paragraph, with no intervening
3411−blank space.
5448+ title = {Spin Wave Dispersion on the {nm} Scale}
34125449
3413−#### Extension: `hard_line_breaks` ####
5450+ Though this is not necessary in bibtex/biblatex, it is necessary
5451+ with citeproc, which stores titles internally in sentence case,
5452+ and converts to title case in styles that require it. Here we
5453+ protect "nm" so that it doesn't get converted to "Nm" at this stage.
34145454
3415−Causes all newlines within a paragraph to be interpreted as hard line
3416−breaks instead of spaces.
5455+If you are using a CSL bibliography (either JSON or YAML), then observe
5456+the following rules:
34175457
3418−#### Extension: `ignore_line_breaks` ####
5458+ - All titles should be in sentence case.
34195459
3420−Causes newlines within a paragraph to be ignored, rather than being
3421−treated as spaces or as hard line breaks. This option is intended for
3422−use with East Asian languages where spaces are not used between words,
3423−but text is divided into lines for readability.
5460+ - Use the `language` field for non-English titles to prevent their
5461+ conversion to title case in styles that call for this. (Conversion
5462+ happens only if `language` begins with `en` or is left empty.)
34245463
3425−#### Extension: `east_asian_line_breaks` ####
5464+ - Protect words that should not be converted to title case using
5465+ this syntax:
34265466
3427−Causes newlines within a paragraph to be ignored, rather than
3428−being treated as spaces or as hard line breaks, when they occur
3429−between two East Asian wide characters. This is a better choice
3430−than `ignore_line_breaks` for texts that include a mix of East
3431−Asian wide characters and other characters.
5467+ Spin wave dispersion on the <span class="nocase">nm</span> scale
34325468
3433−##### Extension: `emoji` ####
5469+### Conference Papers, Published vs. Unpublished
34345470
3435−Parses textual emojis like `:smile:` as Unicode emoticons.
5471+For a formally published conference paper, use the biblatex entry type
5472+`inproceedings` (which will be mapped to CSL `paper-conference`).
34365473
3437−#### Extension: `tex_math_single_backslash` ####
5474+For an unpublished manuscript, use the biblatex entry type
5475+`unpublished` without an `eventtitle` field (this entry type
5476+will be mapped to CSL `manuscript`).
34385477
3439−Causes anything between `\(` and `\)` to be interpreted as inline
3440−TeX math, and anything between `\[` and `\]` to be interpreted
3441−as display TeX math. Note: a drawback of this extension is that
3442−it precludes escaping `(` and `[`.
5478+For a talk, an unpublished conference paper, or a poster
5479+presentation, use the biblatex entry type `unpublished` with an
5480+`eventtitle` field (this entry type will be mapped to CSL
5481+`speech`). Use the biblatex `type` field to indicate the type,
5482+e.g. "Paper", or "Poster". `venue` and `eventdate` may be useful
5483+too, though `eventdate` will not be rendered by most CSL styles.
5484+Note that `venue` is for the event's venue, unlike `location`
5485+which describes the publisher's location; do not use the latter
5486+for an unpublished conference paper.
34435487
3444−#### Extension: `tex_math_double_backslash` ####
34455488
3446−Causes anything between `\\(` and `\\)` to be interpreted as inline
3447−TeX math, and anything between `\\[` and `\\]` to be interpreted
3448−as display TeX math.
5489+## Specifying a citation style
34495490
3450−#### Extension: `markdown_attribute` ####
5491+Citations and references can be formatted using any style supported by the
5492+[Citation Style Language], listed in the [Zotero Style Repository].
5493+These files are specified using the `--csl` option or the `csl`
5494+(or `citation-style`) metadata field. By default, pandoc will
5495+use the [Chicago Manual of Style] author-date format. (You can
5496+override this default by copying a CSL style of your choice
5497+to `default.csl` in your user data directory.)
5498+The CSL project provides further information on [finding and
5499+editing styles].
5500+
5501+The `--citation-abbreviations` option (or the
5502+`citation-abbreviations` metadata field) may be used to specify
5503+a JSON file containing abbreviations of journals that should be
5504+used in formatted bibliographies when `form="short"` is
5505+specified. The format of the file can be illustrated with an
5506+example:
34515507
3452−By default, pandoc interprets material inside block-level tags as Markdown.
3453−This extension changes the behavior so that Markdown is only parsed
3454−inside block-level tags if the tags have the attribute `markdown=1`.
34555508
3456−#### Extension: `mmd_title_block` ####
5509+ { "default": {
5510+ "container-title": {
5511+ "Lloyd's Law Reports": "Lloyd's Rep",
5512+ "Estates Gazette": "EG",
5513+ "Scots Law Times": "SLT"
5514+ }
5515+ }
5516+ }
34575517
3458−Enables a [MultiMarkdown] style title block at the top of
3459−the document, for example:
34605518
3461− Title: My title
3462− Author: John Doe
3463− Date: September 1, 2008
3464− Comment: This is a sample mmd title block, with
3465− a field spanning multiple lines.
5519+## Citations in note styles
34665520
3467−See the MultiMarkdown documentation for details. If `pandoc_title_block` or
3468−`yaml_metadata_block` is enabled, it will take precedence over
3469−`mmd_title_block`.
5521+Pandoc's citation processing is designed to allow you to
5522+move between author-date, numerical, and note styles without
5523+modifying the markdown source. When you're using a note
5524+style, avoid inserting footnotes manually. Instead, insert
5525+citations just as you would in an author-date style---for
5526+example,
34705527
3471−#### Extension: `abbreviations` ####
5528+ Blah blah [@foo, p. 33].
34725529
3473−Parses PHP Markdown Extra abbreviation keys, like
5530+The footnote will be created automatically. Pandoc will take
5531+care of removing the space and moving the note before or
5532+after the period, depending on the setting of
5533+`notes-after-punctuation`, as described below in [Other relevant
5534+metadata fields].
34745535
3475− *[HTML]: Hypertext Markup Language
5536+In some cases you may need to put a citation inside a regular
5537+footnote. Normal citations in footnotes (such as `[@foo, p.
5538+33]`) will be rendered in parentheses. In-text citations (such
5539+as `@foo [p. 33]`) will be rendered without parentheses. (A
5540+comma will be added if appropriate.) Thus:
34765541
3477−Note that the pandoc document model does not support
3478−abbreviations, so if this extension is enabled, abbreviation keys are
3479−simply skipped (as opposed to being parsed as paragraphs).
5542+ [^1]: Some studies [@foo; @bar, p. 33] show that
5543+ frubulicious zoosnaps are quantical. For a survey
5544+ of the literature, see @baz [chap. 1].
34805545
3481−#### Extension: `autolink_bare_uris` ####
5546+## Raw content in a style
34825547
3483−Makes all absolute URIs into links, even when not surrounded by
3484−pointy braces `<...>`.
5548+To include raw content in a prefix, suffix, delimiter, or term,
5549+surround it with these tags indicating the format:

3486−#### Extension: `ascii_identifiers` ####
5551+ {{jats}}<ref>{{/jats}}
34875552
3488−Causes the identifiers produced by `auto_identifiers` to be pure ASCII.
3489−Accents are stripped off of accented Latin letters, and non-Latin
3490−letters are omitted.
5553+Without the tags, the string will be interpreted as a string
5554+and escaped in the output, rather than being passed through raw.
34915555
3492−#### Extension: `mmd_link_attributes` ####
5556+This feature allows stylesheets to be customized to give
5557+different output for different output formats. However,
5558+stylesheets customized in this way will not be usable
5559+by other CSL implementations.
34935560
3494−Parses multimarkdown style key-value attributes on link
3495−and image references. This extension should not be confused with the
3496−[`link_attributes`](#extension-link_attributes) extension.
34975561

5563+## Placement of the bibliography
35025564
3503−#### Extension: `mmd_header_identifiers` ####
5565+If the style calls for a list of works cited, it will be placed
5566+in a div with id `refs`, if one exists:
35045567
3505−Parses multimarkdown style header identifiers (in square brackets,

5571+Otherwise, it will be placed at the end of the document.
5572+Generation of the bibliography can be suppressed by setting
5573+`suppress-bibliography: true` in the YAML metadata.
35095574
3510−Activates the definition list syntax of pandoc 1.12.x and earlier.
3511−This syntax differs from the one described above under [Definition lists]
3512−in several respects:
5575+If you wish the bibliography to have a section heading, you can
5576+set `reference-section-title` in the metadata, or put the heading
5577+at the beginning of the div with id `refs` (if you are using it)
5578+or at the end of your document:
35135579
3514− - No blank line is required between consecutive items of the
3515− definition list.
3516− - To get a "tight" or "compact" list, omit space between consecutive
3517− items; the space between a term and its definition does not affect
3518− anything.
3519− - Lazy wrapping of paragraphs is not allowed: the entire definition must
3520− be indented four spaces.[^6]
5580+ last paragraph...
35215581
3522−[^6]: To see why laziness is incompatible with relaxing the requirement
3523− of a blank line between items, consider the following example:
5582+ # References
35245583
3525− bar
3526− : definition
3527− foo
3528− : definition
5584+The bibliography will be inserted after this heading. Note that
5585+the `unnumbered` class will be added to this heading, so that the
5586+section will not be numbered.
35295587
3530− Is this a single list item with two definitions of "bar," the first of
3531− which is lazily wrapped, or two list items? To remove the ambiguity
3532− we must either disallow lazy wrapping or require a blank line between
3533− list items.

5637+ `de`, `en-US`, `fr-CA`, `ug-Cyrl`. The unicode extension
5638+ syntax (after `-u-`) may be used to specify options for
5639+ collation (sorting) more precisely. Here are some examples:
5640+
5641+ - `zh-u-co-pinyin` -- Chinese with the Pinyin collation.
5642+ - `es-u-co-trad` -- Spanish with the traditional collation
5643+ (with `Ch` sorting after `C`).
5644+ - `fr-u-kb` -- French with "backwards" accent sorting
5645+ (with `coté` sorting after `côte`).
5646+ - `en-US-u-kf-upper` -- English with uppercase letters sorting
5647+ before lower (default is lower before upper).
5648+
5649+`notes-after-punctuation`
5650+: If true (the default), pandoc will put footnote citations
5651+ after following punctuation. For example, if the source
5652+ contains `blah blah [@jones99].`, the result will look like
5653+ `blah blah.[^1]`, with the note moved after the period and

5972+to the first slide-level heading on the slide (which may even be empty).
5973+
5974+In reveal.js's overview mode, the parallaxBackgroundImage will show up
5975+only on the first slide.

5977+Other reveal.js background settings also work on individual slides, including
5978+`data-background-size`, `data-background-repeat`, `data-background-color`,
5979+`data-transition`, and `data-transition-speed`.
5980+
5981+To add a background image to the automatically generated title slide, use the
5982+`title-slide-attributes` variable in the YAML metadata block. It must contain
5983+a map of attribute names and values.

6169+and include it in the EPUB container, yielding a completely
38826170self-contained EPUB. If you want to link to external media resources
38836171instead, use raw HTML in your source and add `data-external="1"` to the tag
38846172with the `src` attribute. For example:

3895−If you append `+lhs` (or `+literate_haskell`) to an appropriate input or output
3896−format (`markdown`, `markdown_strict`, `rst`, or `latex` for input or output;
3897−`beamer`, `html4` or `html5` for output only), pandoc will treat the document as
3898−literate Haskell source. This means that
3899−
3900− - In Markdown input, "bird track" sections will be parsed as Haskell
3901− code rather than block quotations. Text between `\begin{code}`
3902− and `\end{code}` will also be treated as Haskell code. For
3903− ATX-style headers the character '=' will be used instead of '#'.
3904−
3905− - In Markdown output, code blocks with classes `haskell` and `literate`
3906− will be rendered using bird tracks, and block quotations will be
3907− indented one space, so they will not be treated as Haskell code.
3908− In addition, headers will be rendered setext-style (with underlines)
3909− rather than ATX-style (with '#' characters). (This is because ghc
3910− treats '#' characters in column 1 as introducing line numbers.)

6184+taken as code cells, and intervening content will be taken as

6392+## Input
6393+
6394+The docx reader, by default, only reads those styles that it can
6395+convert into pandoc elements, either by direct conversion or
6396+interpreting the derivation of the input document's styles.
6397+
6398+By enabling the [`styles` extension](#ext-styles) in the docx reader
6399+(`-f docx+styles`), you can produce output that maintains the styles
6400+of the input document, using the `custom-style` class. Paragraph
6401+styles are interpreted as divs, while character styles are interpreted
6402+as spans.
6403+
6404+For example, using the `custom-style-reference.docx` file in the test
6405+directory, we have the following different outputs:
6406+
6407+Without the `+styles` extension:
6408+
6409+ $ pandoc test/docx/custom-style-reference.docx -f docx -t markdown
6410+ This is some text.
6411+
6412+ This is text with an *emphasized* text style. And this is text with a
6413+ **strengthened** text style.
6414+
6415+ > Here is a styled paragraph that inherits from Block Text.
6416+
6417+And with the extension:
6418+
6419+ $ pandoc test/docx/custom-style-reference.docx -f docx+styles -t markdown
6420+
6421+ ::: {custom-style="First Paragraph"}
6422+ This is some text.
6423+ :::
6424+
6425+ ::: {custom-style="Body Text"}
6426+ This is text with an [emphasized]{custom-style="Emphatic"} text style.

6428+ text style.
6429+ :::
6430+
6431+ ::: {custom-style="My Block Style"}
6432+ > Here is a styled paragraph that inherits from Block Text.
6433+ :::
6434+
6435+With these custom styles, you can use your input document as a
6436+reference-doc while creating docx output (see below), and maintain the

6455+Note that custom writers have no default template. If you want
6456+to use `--standalone` with a custom writer, you will need to
6457+specify a template manually using `--template` or add a new
6458+default template with the name
6459+`default.NAME_OF_CUSTOM_WRITER.lua` to the `templates`
6460+subdirectory of your user data directory (see [Templates]).
6461+
6462+[Lua]: https://www.lua.org
6463+
6464+# Reproducible builds
6465+
6466+Some of the document formats pandoc targets (such as EPUB,
6467+docx, and ODT) include build timestamps in the generated document.
6468+That means that the files generated on successive builds will
6469+differ, even if the source does not. To avoid this, set the
6470+`SOURCE_DATE_EPOCH` environment variable, and the timestamp will
6471+be taken from it instead of the current time.
6472+`SOURCE_DATE_EPOCH` should contain an integer unix timestamp
6473+(specifying the number of second since midnight UTC January 1, 1970).
6474+
6475+Some document formats also include a unique identifier. For
6476+EPUB, this can be set explicitly by setting the `identifier`
6477+metadata field (see [EPUB Metadata], above).
6478+
6479+# A note on security
6480+
6481+If you use pandoc to convert user-contributed content in a web
6482+application, here are some things to keep in mind:
6483+
6484+1. Although pandoc itself will not create or modify any files other
6485+ than those you explicitly ask it create (with the exception
6486+ of temporary files used in producing PDFs), a filter or custom
6487+ writer could in principle do anything on your file system. Please
6488+ audit filters and custom writers very carefully before using them.
6489+
6490+2. If your application uses pandoc as a Haskell library (rather than
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
6493+ pandoc operations in the `PandocPure` monad. See the document
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
6502+ the heap size to 512MB.
6503+
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,
6507+ users can include dangerous content in URLs and attributes.
6508+ To be safe, you should run all the generated HTML through
6509+ an HTML sanitizer.
