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`.
135+
136+When using LaTeX, the following packages need to be available
137+(they are included with all recent versions of [TeX Live]):
138+[`amsfonts`], [`amsmath`], [`lm`], [`unicode-math`],
139+[`iftex`], [`listings`] (if the

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
155+rendering]. The following packages will be used to improve

157+be present: [`upquote`] (for straight quotes in verbatim

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:

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

1864+### For loops
12041865
1205−Variables are available for [producing slide shows with pandoc],
1206−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.
12071869
1208−`slidy-url`
1209−: base URL for Slidy documents (defaults to
1210− `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

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.
12111877

1230− are `frame`, `vertical`, and `horizontal`).
1896+You may optionally specify a separator between consecutive

1898+material between `sep` and the `endfor` is the separator.
12311899

1283− 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`.
12841961
1285−`fontfamilyoptions`
1286−: options for package used as `fontfamily`: e.g. `osf,sc` with

1962+Final newlines are omitted from included partials.
12891963
1290−`mainfont`, `sansfont`, `monofont`, `mathfont`, `CJKmainfont`
1291−: font families for use with `xelatex` or
1292− `lualatex`: take the name of any system font, using the
1293− [`fontspec`] package. Note that if `CJKmainfont` is used,
1294− the [`xecjk`] package must be available.
1964+Partials may include other partials.
12951965
1296−`mainfontoptions`, `sansfontoptions`, `monofontoptions`, `mathfontoptions`, `CJKoptions`
1297−: options to use with `mainfont`, `sansfont`, `monofont`, `mathfont`,
1298− `CJKmainfont` in `xelatex` and `lualatex`. Allow for any choices
1299− available through [`fontspec`], such as the OpenType features
1300− `Numbers=OldStyle,Numbers=Proportional`. May be repeated for multiple options.
1966+A separator between values of an array may be specified
1967+in square brackets, immediately after the variable name
1968+or partial:
1969+
1970+```
1971+${months[, ]}$
1972+
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`).

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[

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:

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)

2493+
2494+ ---
2495+ fontfamily: libertinus
2496+ fontfamilyoptions:
2497+ - osf
2498+ - p
2499+ ...
2500+

2516+ Palatino with lowercase figures:
2517+

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+

2759+`include-after`
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+
2767+`numbersections`
2768+: non-null value if `-N/--number-sections` was specified
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`
2792+: non-null value if `--toc/--table-of-contents` was specified
2793+
2794+`toc-title`
2795+: title of table of contents (works only with EPUB,
2796+ HTML, opendocument, odt, docx, pptx, beamer, LaTeX)

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`
2870+
2871+The default algorithm used to derive the identifier from the
2872+heading text is:
2873+
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`.
13052883
1306−`colorlinks`
1307−: add color to link text; automatically enabled if any of `linkcolor`, `citecolor`,
1308− `urlcolor`, or `toccolor` are set
2884+Thus, for example,
13092885
1310−`linkcolor`, `citecolor`, `urlcolor`, `toccolor`
1311−: color for internal links, citation links, external links, and links in table of contents:
1312− uses any of the [predefined LaTeX colors]
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`
13132894
1314−`links-as-notes`
1315−: causes links to be printed as footnotes
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.
13162900
1317−`indent`
1318−: uses document class settings for indentation (the default LaTeX template
1319− otherwise removes indentation and adds space between paragraphs)
2901+(However, a different algorithm is used if
2902+`gfm_auto_identifiers` is enabled; see below.)
13202903
1321−`subparagraph`
1322−: disables default behavior of LaTeX template that redefines (sub)paragraphs
1323− as sections, changing the appearance of nested headings in some classes
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:
13242908
1325−`thanks`
1326−: specifies contents of acknowledgments footnote after document title.
2909+ See the section on
2910+ [heading identifiers](#heading-identifiers-in-html-latex-and-context).
13272911
1328−`toc`
1329−: include table of contents (can also be set using `--toc/--table-of-contents`)
2912+Note, however, that this method of providing links to sections works
2913+only in HTML, LaTeX, and ConTeXt formats.
13302914
1331−`toc-depth`
1332−: level of section to include in table of contents
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.
13332921
1334−`secnumdepth`
1335−: numbering depth for sections, if sections are numbered
2922+#### Extension: `ascii_identifiers` ####
13362923
1337−`lof`, `lot`
1338−: include list of figures, list of tables
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.
13392927
1340−`bibliography`
1341−: bibliography to use for resolving references
2928+#### Extension: `gfm_auto_identifiers` ####
13422929
1343−`biblio-style`
1344−: bibliography style, when used with `--natbib` and `--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.
13452935
1346−`biblio-title`
1347−: bibliography title, when used with `--natbib` and `--biblatex`.
2936+## Math Input
13482937
1349−`biblatexoptions`
1350−: list of options for biblatex.
2938+The extensions [`tex_math_dollars`](#extension-tex_math_dollars),
2939+[`tex_math_single_backslash`](#extension-tex_math_single_backslash), and
2940+[`tex_math_double_backslash`](#extension-tex_math_double_backslash)
2941+are described in the section about Pandoc's Markdown.

1363−---------------------
2946+## Raw HTML/TeX
13642947
1365−`papersize`
1366−: paper size, e.g. `letter`, `A4`, `landscape` (see [ConTeXt Paper Setup]);
1367− may be repeated for multiple options
2948+The following extensions are described in more detail in
2949+their respective sections of [Pandoc's Markdown]:
13682950
1369−`layout`
1370−: options for page margins and text arrangement (see [ConTeXt Layout]);
1371− may be repeated for multiple options
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.
13722954
1373−`margin-left`, `margin-right`, `margin-top`, `margin-bottom`
1374−: sets margins, if `layout` is not used (otherwise `layout`
1375− overrides these)
2955+- [`raw_tex`](#extension-raw_tex) allows raw LaTeX, TeX, and ConTeXt
2956+ to be included in a document. This extension can be enabled/disabled
2957+ for the following formats (in addition to `markdown`):
13762958
1377−`fontsize`
1378−: font size for body text (e.g. `10pt`, `12pt`)
2959+ input formats
2960+ : `latex`, `textile`, `html` (environments, `\ref`, and
2961+ `\eqref` only), `ipynb`
13792962
1380−`mainfont`, `sansfont`, `monofont`, `mathfont`
1381−: font families: take the name of any system font (see [ConTeXt Font Switching])
2963+ output formats
2964+ : `textile`, `commonmark`
13822965
1383−`linkcolor`, `contrastcolor`
1384−: color for links outside and inside a page, e.g. `red`, `blue` (see [ConTeXt Color])
2966+ Note: as applied to `ipynb`, `raw_html` and `raw_tex` affect not
2967+ only raw TeX in markdown cells, but data with mime type
2968+ `text/html` in output cells. Since the `ipynb` reader attempts
2969+ to preserve the richest possible outputs when several options
2970+ are given, you will get best results if you disable `raw_html`
2971+ and `raw_tex` when converting to formats like `docx` which don't
2972+ allow raw `html` or `tex`.
13852973
1386−`linkstyle`
1387−: typeface style for links, e.g. `normal`, `bold`, `slanted`, `boldslanted`, `type`, `cap`, `small`
2974+- [`native_divs`](#extension-native_divs) causes HTML `div`
2975+ elements to be parsed as native pandoc Div blocks.
2976+ If you want them to be parsed as raw HTML, use
2977+ `-f html-native_divs+raw_html`.
13882978
1389−`indenting`
1390−: controls indentation of paragraphs, e.g. `yes,small,next` (see [ConTeXt Indentation]);
1391− may be repeated for multiple options
2979+- [`native_spans`](#extension-native_spans) causes HTML `span`
2980+ elements to be parsed as native pandoc Span inlines.
2981+ If you want them to be parsed as raw HTML, use
2982+ `-f html-native_spans+raw_html`. If you want to drop all
2983+ `div`s and `span`s when converting HTML to Markdown, you
2984+ can use `pandoc -f html-native_divs-native_spans -t markdown`.
13922985
1393−`whitespace`
1394−: spacing between paragraphs, e.g. `none`, `small` (using [`setupwhitespace`])
2986+## Literate Haskell support
13952987
1396−`interlinespace`
1397−: adjusts line spacing, e.g. `4ex` (using [`setupinterlinespace`]);

2990+Treat the document as literate Haskell source.
14032991
1404−`pagenumbering`
1405−: page number style and location (using [`setuppagenumbering`]);

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
14233003
1424−Variables for man pages
1425−-----------------------
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 '#'.
14263008
1427−`section`
1428−: section number 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.)
14293015
1430−`header`
1431−: header in man pages
3016+ - In restructured text input, "bird track" sections will be parsed
3017+ as Haskell code.
14323018
1433−`footer`
1434−: footer in man pages
3019+ - In restructured text output, code blocks with class `haskell` will
3020+ be rendered using bird tracks.
14353021
1436−`adjusting`
1437−: adjusts text to left (`l`), right (`r`), center (`c`),
1438− or both (`b`) margins
3022+ - In LaTeX input, text in `code` environments will be parsed as
3023+ Haskell code.
14393024
1440−`hyphenate`
1441−: if `true` (the default), hyphenation will be used
3025+ - In LaTeX output, code blocks with class `haskell` will be rendered
3026+ inside `code` environments.
14423027
1443−Using variables in templates
1444−----------------------------
3028+ - In HTML output, code blocks with class `haskell` will be rendered
3029+ with class `literatehaskell` and bird tracks.
14453030
1446−Variable names are sequences of alphanumerics, `-`, and `_`,
1447−starting with a letter. A variable name surrounded by `$` signs
1448−will be replaced by its value. For example, the string `$title$` in
3031+Examples:
14493032
1450− <title>$title$</title>
3033+ pandoc -f markdown+lhs -t html
14513034
1452−will be replaced by the document title.
3035+reads literate Haskell source formatted with Markdown conventions and writes
3036+ordinary HTML (without bird tracks).
14533037
1454−To write a literal `$` in a template, use `$$`.
3038+ pandoc -f markdown+lhs -t html+lhs
14553039
1456−Templates may contain conditionals. The syntax is as follows:
3040+writes HTML with the Haskell code in bird tracks, so it can be copied
3041+and pasted as literate Haskell source.
14573042
1458− $if(variable)$
1459− X
1460− $else$
1461− Y
1462− $endif$
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.
14633046
1464−This will include `X` in the template if `variable` has a non-null
1465−value; otherwise it will include `Y`. `X` and `Y` are placeholders for
1466−any valid template text, and may include interpolated variables or other
1467−conditionals. The `$else$` section may be omitted.
3047+## Other extensions
14683048
1469−When variables can have multiple values (for example, `author` in
1470−a multi-author document), you can use the `$for$` keyword:
3049+#### Extension: `empty_paragraphs` ####
14713050
1472− $for(author)$
1473− <meta name="author" content="$author$" />
1474− $endfor$
3051+Allows empty paragraphs. By default empty paragraphs are
3052+omitted.
14753053
1476−You can optionally specify a separator to be used between
1477−consecutive items:
3054+This extension can be enabled/disabled for the following formats:

1479− $for(author)$$author$$sep$, $endfor$
3056+input formats
3057+: `docx`, `html`
14803058
1481−A dot can be used to select a field of a variable that takes
1482−an object as its value. So, for example:
3059+output formats
3060+: `docx`, `odt`, `opendocument`, `html`
14833061
1484− $author.name$ ($author.affiliation$)
3062+#### Extension: `native_numbering` ####
14853063
1486−If you use custom templates, you may need to revise them as pandoc
1487−changes. We recommend tracking the changes in the default templates,
1488−and modifying your custom templates accordingly. An easy way to do this
1489−is to fork the [pandoc-templates] repository and merge in changes after each
1490−pandoc release.
3064+Enables native numbering of figures and tables. Enumeration

3067+This extension can be enabled/disabled for the following formats:
3068+
3069+output formats
3070+: `odt`, `opendocument`
3071+
3072+#### Extension: `xrefs_name` ####
3073+
3074+Links to headings, figures and tables inside the document are
3075+substituted with cross-references that will use the name or caption
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
3079+name.
3080+
3081+Text in cross-references is only made consistent with the referenced
3082+item once the document has been refreshed.
3083+
3084+This extension can be enabled/disabled for the following formats:
3085+
3086+output formats
3087+: `odt`, `opendocument`
3088+
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+

4857+## Divs and Spans
4858+
4859+Using the `native_divs` and `native_spans` extensions
4860+(see [above][Extension: `native_divs`]), HTML syntax can
4861+be used as part of markdown to create native `Div` and `Span`
4862+elements in the pandoc AST (as opposed to raw HTML).
4863+However, there is also nicer syntax available:
4864+
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.
4878+
4879+Example:
4880+
4881+ ::::: {#special .sidebar}
4882+ Here is a paragraph.
4883+
4884+ And another.
4885+ :::::

4897+
4898+Fences without attributes are always closing fences. Unlike
4899+with fenced code blocks, the number of colons in the closing
4900+fence need not match the number in the opening fence. However,
4901+it can be helpful for visual clarity to use fences of different

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
5270+
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)

5312+`gfm`, and `commonmark_x` are defined relative to default
5313+commonmark. So, for example, `backtick_code_blocks`

3383−Non-pandoc extensions
3384−---------------------
5421+Running pandoc on a bibliography file with the `--citeproc`
5422+option will create a formatted bibliography in the format
5423+of your choice:
33855424
3386−The following Markdown syntax extensions are not enabled by default
3387−in pandoc, but may be enabled by adding `+EXTENSION` to the format
3388−name, where `EXTENSION` is the name of the extension. Thus, for
3389−example, `markdown+hard_line_breaks` is Markdown with hard line breaks.
5425+ pandoc chem.bib -s --citeproc -o chem.html
5426+ pandoc chem.bib -s --citeproc -o chem.pdf
33905427
3391−#### Extension: `angle_brackets_escapable` ####
5428+### Capitalization in titles
33925429
3393−Allow `<` and `>` to be backslash-escaped, as they can be in
3394−GitHub flavored Markdown but not original Markdown. This is
3395−implied by pandoc's default `all_symbols_escapable`.
5430+If you are using a bibtex or biblatex bibliography, then observe
5431+the following rules:
33965432
3397−#### Extension: `lists_without_preceding_blankline` ####
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`.)
33985438
3399−Allow a list to occur right after a paragraph, with no intervening
3400−blank space.
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:
34015442
3402−#### Extension: `hard_line_breaks` ####
5443+ title = {My Dinner with {Andre}}
34035444
3404−Causes all newlines within a paragraph to be interpreted as hard line
3405−breaks instead of spaces.
5445+ - In addition, words that should remain lowercase (or camelCase)
5446+ should be protected:
34065447
3407−#### Extension: `ignore_line_breaks` ####
5448+ title = {Spin Wave Dispersion on the {nm} Scale}
34085449
3409−Causes newlines within a paragraph to be ignored, rather than being
3410−treated as spaces or as hard line breaks. This option is intended for
3411−use with East Asian languages where spaces are not used between words,
3412−but text is divided into lines for readability.
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.
34135454
3414−#### Extension: `east_asian_line_breaks` ####
5455+If you are using a CSL bibliography (either JSON or YAML), then observe
5456+the following rules:
34155457
3416−Causes newlines within a paragraph to be ignored, rather than
3417−being treated as spaces or as hard line breaks, when they occur
3418−between two East Asian wide characters. This is a better choice
3419−than `ignore_line_breaks` for texts that include a mix of East
3420−Asian wide characters and other characters.
5458+ - All titles should be in sentence case.
34215459
3422−##### Extension: `emoji` ####
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.)
34235463
3424−Parses textual emojis like `:smile:` as Unicode emoticons.
5464+ - Protect words that should not be converted to title case using
5465+ this syntax:
34255466
3426−#### Extension: `tex_math_single_backslash` ####
5467+ Spin wave dispersion on the <span class="nocase">nm</span> scale
34275468
3428−Causes anything between `\(` and `\)` to be interpreted as inline
3429−TeX math, and anything between `\[` and `\]` to be interpreted
3430−as display TeX math. Note: a drawback of this extension is that
3431−it precludes escaping `(` and `[`.
5469+### Conference Papers, Published vs. Unpublished
34325470
3433−#### Extension: `tex_math_double_backslash` ####
5471+For a formally published conference paper, use the biblatex entry type
5472+`inproceedings` (which will be mapped to CSL `paper-conference`).
34345473
3435−Causes anything between `\\(` and `\\)` to be interpreted as inline
3436−TeX math, and anything between `\\[` and `\\]` to be interpreted
3437−as display TeX math.
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−#### Extension: `markdown_attribute` ####
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.
34405487
3441−By default, pandoc interprets material inside block-level tags as Markdown.
3442−This extension changes the behavior so that Markdown is only parsed
3443−inside block-level tags if the tags have the attribute `markdown=1`.
34445488
3445−#### Extension: `mmd_title_block` ####
5489+## Specifying a citation style
34465490
3447−Enables a [MultiMarkdown] style title block at the top of
3448−the document, for example:
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:

3450− Title: My title
3451− Author: John Doe
3452− Date: September 1, 2008

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,
34655527
3466−Note that the pandoc document model does not support
3467−abbreviations, so if this extension is enabled, abbreviation keys are
3468−simply skipped (as opposed to being parsed as paragraphs).
5528+ Blah blah [@foo, p. 33].
34695529
3470−#### Extension: `autolink_bare_uris` ####
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].
34715535
3472−Makes all absolute URIs into links, even when not surrounded by
3473−pointy braces `<...>`.
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:
34745541
3475−#### Extension: `ascii_identifiers` ####
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].
34765545
3477−Causes the identifiers produced by `auto_identifiers` to be pure ASCII.
3478−Accents are stripped off of accented latin letters, and non-latin
3479−letters are omitted.
5546+## Raw content in a style
34805547
3481−#### Extension: `mmd_link_attributes` ####
5548+To include raw content in a prefix, suffix, delimiter, or term,
5549+surround it with these tags indicating the format:
34825550
3483−Parses multimarkdown style key-value attributes on link

5962+or as a command-line variable. (There are no other options in
5963+beamer and the rest of this section concerns reveal.js slideshows.)
5964+
5965+For reveal.js, you can instead use the reveal.js-native option
5966+`parallaxBackgroundImage`. You can also set `parallaxBackgroundHorizontal`
5967+and `parallaxBackgroundVertical` the same way and must also set
5968+`parallaxBackgroundSize` to have your values take effect.
5969+
5970+To set an image for a particular reveal.js slide, add
5971+`{data-background-image="/path/to/image"}`
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.
5976+
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.

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.

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

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.
