2134+### Metadata variables
2136+`title`, `author`, `date`

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`]:
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.
2157+: document subtitle, included in HTML, EPUB, LaTeX, ConTeXt, and docx
2161+: document summary, included in LaTeX, ConTeXt, AsciiDoc, and docx
2165+: list of keywords to be included in HTML, PDF, ODT, pptx, docx
2166+ and AsciiDoc metadata; repeat as for `author`, above

2176+: document category, included in docx and pptx metadata
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:
2184+ title: 'This is the title'
2185+ subtitle: "This is the subtitle"
2193+ It consists of two paragraphs
2196+will include `title`, `author` and `description` as standard document
2197+properties and `subtitle` as a custom property when converting to docx,
2200+### Language variables
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.
2209+ Use native pandoc [Divs and Spans] with the `lang` attribute to
2210+ switch the language:
2216+ Text in the main document language (British English).
2219+ > Cette citation est écrite en français canadien.
2222+ More text in English. ['Zitat auf Deutsch.']{lang=de}
2225+: the base script direction, either `rtl` (right-to-left)
2226+ or `ltr` (left-to-right).
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].
2235+ When using LaTeX for bidirectional documents, only the
2236+ `xelatex` engine is fully supported (use
2237+ `--pdf-engine=xelatex`).

1623`margin-left`, `margin-right`, `margin-top`, `margin-bottom`
2281`margin-left`, `margin-right`, `margin-top`, `margin-bottom`
2282+: sets the corresponding CSS `padding` properties on the `body` element.
2284+To override or extend some [CSS] for just one document, include for example:

4965+brackets, with semicolons separating distinct items:
4967+ Blah blah [@doe99; @smith2000; @smith2004].
4969+How this is rendered depends on the citation style. In an
4970+author-date style, it might render as
4972+ Blah blah (Doe 1999, Smith 2000, 2004).
4974+In a footnote style, it might render as

4980+ Susan Smith, "Bees," *Journal of Insects* (2004).
4982+See the [CSL user documentation] for more information about CSL
4983+styles and how they affect rendering.
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]`.
4995+Citation items may optionally include a prefix, a locator, and
4998+ Blah blah [see @doe99, pp. 33-35 and *passim*; @smith04, chap. 1].
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.
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.
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:
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]
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:
5030+ Smith says blah [-@smith04].
5032+You can also write an author-in-text citation, by omitting the
5035+ @smith04 says blah.
5037+ @smith04 [p. 33] says blah.
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.
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
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.
5067+#### Extension: `rebase_relative_paths` ####
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.
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
5083+ pandoc chap*/*.md -f markdown+rebase_relative_paths
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.
5090+Absolute paths and URLs are not changed. Neither are empty
5091+paths or paths consisting entirely of a fragment, e.g., `#foo`.
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.
5098+#### Extension: `attributes` ####
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`].
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
5111+- Consecutive attribute specifiers may be used,
5112+ either for blocks or for inlines. Their attributes
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
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.
5129+#### Extension: `old_dashes` ####
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.
5136+#### Extension: `angle_brackets_escapable` ####
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`.
5142+#### Extension: `lists_without_preceding_blankline` ####
5144+Allow a list to occur right after a paragraph, with no intervening
5147+#### Extension: `four_space_rule` ####
5149+Selects the pandoc <= 2.0 behavior for parsing lists, so that
5150+four spaces indent are needed for list item continuation
5153+#### Extension: `spaced_reference_links` ####
5155+Allow whitespace between the two components of a reference link,
5160+#### Extension: `hard_line_breaks` ####
5162+Causes all newlines within a paragraph to be interpreted as hard line
5163+breaks instead of spaces.
5165+#### Extension: `ignore_line_breaks` ####
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.
5172+#### Extension: `east_asian_line_breaks` ####
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.
5180+#### Extension: `emoji` ####
5182+Parses textual emojis like `:smile:` as Unicode emoticons.
5184+#### Extension: `tex_math_single_backslash` ####
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 `[`.
5191+#### Extension: `tex_math_double_backslash` ####
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.
5197+#### Extension: `markdown_attribute` ####
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`.
5203+#### Extension: `mmd_title_block` ####
5205+Enables a [MultiMarkdown] style title block at the top of
5206+the document, for example:
5210+ Date: September 1, 2008
5211+ Comment: This is a sample mmd title block, with
5212+ a field spanning multiple lines.
5214+See the MultiMarkdown documentation for details. If `pandoc_title_block` or
5215+`yaml_metadata_block` is enabled, it will take precedence over
5218+#### Extension: `abbreviations` ####
5220+Parses PHP Markdown Extra abbreviation keys, like
5222+ *[HTML]: Hypertext Markup Language
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).
5228+#### Extension: `autolink_bare_uris` ####
5230+Makes all absolute URIs into links, even when not surrounded by
5231+pointy braces `<...>`.
5233+#### Extension: `mmd_link_attributes` ####
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.
5239+ This is a reference ![image][ref] with multimarkdown attributes.
5241+ [ref]: https://path.to/image "Image title" width=20px height=30px
5242+ id=myId class="myClass1 myClass2"
5244+#### Extension: `mmd_header_identifiers` ####
5246+Parses multimarkdown style heading identifiers (in square brackets,
5247+after the heading but before any trailing `#`s in an ATX heading).
5249+#### Extension: `compact_definition_lists` ####
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:
5255+ - No blank line is required between consecutive items of the
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
5260+ - Lazy wrapping of paragraphs is not allowed: the entire definition must
5261+ be indented four spaces.[^6]
5263+[^6]: To see why laziness is incompatible with relaxing the requirement
5264+ of a blank line between items, consider the following example:
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
5276+#### Extension: `gutenberg` ####
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.
5282+ [Project Gutenberg]: https://www.gutenberg.org
5284+#### Extension: `sourcepos` ####
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.
5291+## Markdown variants
5293+In addition to pandoc's extended Markdown, the following Markdown
5294+variants are supported:
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)
5304+To see which extensions are supported for a given format,
5305+and which are enabled by default, you can use the command
5307+ pandoc --list-extensions=FORMAT
5309+where `FORMAT` is replaced with the name of the format.
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.

4731−Custom Styles in Docx
6341+# Custom Styles
4732−=====================
6342+
6343+Custom styles can be used in the docx and ICML formats.
6347+By default, pandoc's docx and ICML output applies a predefined set of styles
6348+for blocks such as paragraphs and block quotes, and uses largely default
6349+formatting (italics, bold) for inlines. This will work for most
6350+purposes, especially alongside a `reference.docx` file. However, if you
6351+need to apply your own styles to blocks, or match a preexisting set of
6352+styles, pandoc allows you to define custom styles for blocks and text
6353+using `div`s and `span`s, respectively.
6355+If you define a `div` or `span` with the attribute `custom-style`,
6356+pandoc will apply your specified style to the contained elements (with
6357+the exception of elements whose function depends on a style, like
6358+headings, code blocks, block quotes, or links). So, for example, using
6359+the `bracketed_spans` syntax,
6361+ [Get out]{custom-style="Emphatically"}, he said.
6363+would produce a docx file with "Get out" styled with character
6364+style `Emphatically`. Similarly, using the `fenced_divs` syntax,
6366+ Dickinson starts the poem simply:

6369+ | A Bird came down the Walk---
6370+ | He did not know I saw---
6373+would style the two contained lines with the `Poetry` paragraph style.
6375+For docx output, styles will be defined in the output file as inheriting
6376+from normal text, if the styles are not yet in your reference.docx.
6377+If they are already defined, pandoc will not alter the definition.
6379+This feature allows for greatest customization in conjunction with
6380+[pandoc filters]. If you want all paragraphs after block quotes to be
6381+indented, you can write a filter to apply the styles necessary. If you
6382+want all italics to be transformed to the `Emphasis` character style
6383+(perhaps to change their color), you can write a filter which will
6384+transform all italicized inlines to inlines within an `Emphasis`
6385+custom-style `span`.
6387+For docx output, you don't need to enable any extensions for

6464+# Reproducible builds
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).
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).
6479+# A note on security
6481+If you use pandoc to convert user-contributed content in a web
6482+application, here are some things to keep in mind:
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.
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)
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.
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
