1707+Default files can be placed in the `defaults` subdirectory of

2736+on the output format, and include the following:
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`),

2798+[pandoc-templates]: https://github.com/jgm/pandoc-templates
2802+The behavior of some of the readers and writers can be adjusted by
2803+enabling or disabling various extensions.
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.
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.
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`).
2823+#### Extension: `smart` ####
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."
2829+This extension can be enabled/disabled for the following formats:
2832+: `markdown`, `commonmark`, `latex`, `mediawiki`, `org`, `rst`, `twiki`
2835+: `markdown`, `latex`, `context`, `rst`
2837+enabled by default in
2838+: `markdown`, `latex`, `context` (both input and output)
2840+Note: If you are *writing* Markdown, then the `smart` extension
2841+has the reverse effect: what would have been curly quotes comes
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.
2853+## Headings and sections
2855+#### Extension: `auto_identifiers` ####
2857+A heading without an explicitly specified identifier will be
2858+automatically assigned a unique identifier based on the heading text.
2860+This extension can be enabled/disabled for the following formats:
2863+: `markdown`, `latex`, `rst`, `mediawiki`, `textile`
2866+: `markdown`, `muse`
2868+enabled by default in

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).

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.
2901+(However, a different algorithm is used if
2902+`gfm_auto_identifiers` is enabled; see below.)
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:
2910+ [heading identifiers](#heading-identifiers-in-html-latex-and-context).
2912+Note, however, that this method of providing links to sections works
2913+only in HTML, LaTeX, and ConTeXt formats.
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

2924+Causes the identifiers produced by `auto_identifiers` to be pure ASCII.
2925+Accents are stripped off of accented Latin letters, and non-Latin

2928+#### Extension: `gfm_auto_identifiers` ####
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.
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.
2943+However, they can also be used with HTML input. This is handy for
2944+reading web pages formatted using MathJax, for example.
2948+The following extensions are described in more detail in
2949+their respective sections of [Pandoc's Markdown]:
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.
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`):
2960+ : `latex`, `textile`, `html` (environments, `\ref`, and
2961+ `\eqref` only), `ipynb`
2964+ : `textile`, `commonmark`
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`.
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`.
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`.
2986+## Literate Haskell support
2988+#### Extension: `literate_haskell` ####
2990+Treat the document as literate Haskell source.
2992+This extension can be enabled/disabled for the following formats:
2995+: `markdown`, `rst`, `latex`
2998+: `markdown`, `rst`, `latex`, `html`
3000+If you append `+lhs` (or `+literate_haskell`) to one of the formats
3001+above, pandoc will treat the document as literate Haskell source.
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 '#'.
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.)
3016+ - In restructured text input, "bird track" sections will be parsed
3019+ - In restructured text output, code blocks with class `haskell` will
3020+ be rendered using bird tracks.
3022+ - In LaTeX input, text in `code` environments will be parsed as
3025+ - In LaTeX output, code blocks with class `haskell` will be rendered
3026+ inside `code` environments.
3028+ - In HTML output, code blocks with class `haskell` will be rendered
3029+ with class `literatehaskell` and bird tracks.
3033+ pandoc -f markdown+lhs -t html
3035+reads literate Haskell source formatted with Markdown conventions and writes
3036+ordinary HTML (without bird tracks).
3038+ pandoc -f markdown+lhs -t html+lhs
3040+writes HTML with the Haskell code in bird tracks, so it can be copied
3041+and pasted as literate Haskell source.
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.
3049+#### Extension: `empty_paragraphs` ####
3051+Allows empty paragraphs. By default empty paragraphs are
3054+This extension can be enabled/disabled for the following formats:
3060+: `docx`, `odt`, `opendocument`, `html`
3062+#### Extension: `native_numbering` ####
3064+Enables native numbering of figures and tables. Enumeration
3067+This extension can be enabled/disabled for the following formats:
3070+: `odt`, `opendocument`
3072+#### Extension: `xrefs_name` ####
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
3081+Text in cross-references is only made consistent with the referenced
3082+item once the document has been refreshed.
3084+This extension can be enabled/disabled for the following formats:
3087+: `odt`, `opendocument`
3089+#### Extension: `xrefs_number` ####
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.
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.
3101+Numbers in cross-references are only visible in the final document once
3102+it has been refreshed.
3104+This extension can be enabled/disabled for the following formats:
3107+: `odt`, `opendocument`
3109+#### Extension: `styles` #### {#ext-styles}
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.
3120+#### Extension: `amuse` ####
3122+In the `muse` input format, this enables Text::Amuse
3123+extensions to Emacs Muse markup.
3125+#### Extension: `raw_markdown` ####
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
3133+#### Extension: `citations` {#org-citations}
3135+Some aspects of [Pandoc's Markdown citation syntax](#citations)
3136+are also accepted in `org` input.
3138+#### Extension: `element_citations` ####
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.
3145+#### Extension: `ntb` ####
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.
3156+Pandoc understands an extended and slightly revised version of
3157+John Gruber's [Markdown] syntax. This document explains the syntax,
3158+noting differences from standard Markdown. Except where noted, these
3159+differences can be suppressed by using the `markdown_strict` format instead
3160+of `markdown`. Extensions can be enabled or disabled to specify the
3161+behavior more granularly. They are described in the following. See also
3162+[Extensions] above, for extensions that work also on other formats.
3166+Markdown is designed to be easy to write, and, even more importantly,
3169+> A Markdown-formatted document should be publishable as-is, as plain
3170+> text, without looking like it's been marked up with tags or formatting
3172+> -- [John Gruber](https://daringfireball.net/projects/markdown/syntax#philosophy)
3174+This principle has guided pandoc's decisions in finding syntax for
3175+tables, footnotes, and other extensions.
3177+There is, however, one respect in which pandoc's aims are different
3178+from the original aims of Markdown. Whereas Markdown was originally
3179+designed with HTML generation in mind, pandoc is designed for multiple
3180+output formats. Thus, while pandoc allows the embedding of raw HTML,
3181+it discourages it, and provides other, non-HTMLish ways of representing
3182+important document elements like definition lists, tables, mathematics, and
3187+A paragraph is one or more lines of text followed by one or more blank lines.
3188+Newlines are treated as spaces, so you can reflow your paragraphs as you like.
3189+If you need a hard line break, put two or more spaces at the end of a line.
3191+#### Extension: `escaped_line_breaks` ####
3193+A backslash followed by a newline is also a hard line break.
3194+Note: in multiline and grid table cells, this is the only way
3195+to create a hard line break, since trailing spaces in the cells
3200+There are two kinds of headings: Setext and ATX.
3202+### Setext-style headings ###
3204+A setext-style heading is a line of text "underlined" with a row of `=` signs
3205+(for a level-one heading) or `-` signs (for a level-two heading):
3207+ A level-one heading
3208+ ===================
3210+ A level-two heading
3211+ -------------------
3213+The heading text can contain inline formatting, such as emphasis (see
3214+[Inline formatting], below).
3217+### ATX-style headings ###
3219+An ATX-style heading consists of one to six `#` signs and a line of
3220+text, optionally followed by any number of `#` signs. The number of
3221+`#` signs at the beginning of the line is the heading level:
3223+ ## A level-two heading
3225+ ### A level-three heading ###
3227+As with setext-style headings, the heading text can contain formatting:
3229+ # A level-one heading with a [link](/url) and *emphasis*
3231+#### Extension: `blank_before_header` ####
3233+Standard Markdown syntax does not require a blank line before a heading.
3234+Pandoc does require this (except, of course, at the beginning of the
3235+document). The reason for the requirement is that it is all too easy for a
3236+`#` to end up at the beginning of a line by accident (perhaps through line
3237+wrapping). Consider, for example:
3239+ I like several of their flavors of ice cream:
3240+ #22, for example, and #5.
3242+#### Extension: `space_in_atx_header` ####
3244+Many Markdown implementations do not require a space between the
3245+opening `#`s of an ATX heading and the heading text, so that
3246+`#5 bolt` and `#hashtag` count as headings. With this extension,
3247+pandoc does require the space.
3249+### Heading identifiers ###
3251+See also the [`auto_identifiers`
3252+extension](#extension-auto_identifiers) above.
3254+#### Extension: `header_attributes` ####
3256+Headings can be assigned attributes using this syntax at the end
3257+of the line containing the heading text:
3259+ {#identifier .class .class key=value key=value}
3261+Thus, for example, the following headings will all be assigned the identifier
3264+ # My heading {#foo}
3266+ ## My heading ## {#foo}
3268+ My other heading {#foo}
3271+(This syntax is compatible with [PHP Markdown Extra].)
3273+Note that although this syntax allows assignment of classes and key/value
3274+attributes, writers generally don't use all of this information. Identifiers,
3275+classes, and key/value attributes are used in HTML and HTML-based formats such
3276+as EPUB and slidy. Identifiers are used for labels and link anchors in the
3277+LaTeX, ConTeXt, Textile, Jira markup, and AsciiDoc writers.
3279+Headings with the class `unnumbered` will not be numbered, even if
3280+`--number-sections` is specified. A single hyphen (`-`) in an attribute
3281+context is equivalent to `.unnumbered`, and preferable in non-English
3288+ # My heading {.unnumbered}
3290+If the `unlisted` class is present in addition to `unnumbered`,
3291+the heading will not be included in a table of contents.
3292+(Currently this feature is only implemented for certain
3293+formats: those based on LaTeX and HTML, PowerPoint, and RTF.)
3295+#### Extension: `implicit_header_references` ####
3297+Pandoc behaves as if reference links have been defined for each heading.
3298+So, to link to a heading

4814+ and a reference ![image][ref] with attributes.
4816+ [ref]: foo.jpg "optional title" {#id .class key=val key2="val 2"}
4818+(This syntax is compatible with [PHP Markdown Extra] when only `#id`
4819+and `.class` are used.)
4821+For HTML and EPUB, all known HTML5 attributes except `width` and
4822+`height` (but including `srcset` and `sizes`) are passed through
4823+as is. Unknown attributes are passed through as custom
4824+attributes, with `data-` prepended. The other writers ignore
4825+attributes that are not specifically supported by their output format.
4827+The `width` and `height` attributes on images are treated specially. When
4828+used without a unit, the unit is assumed to be pixels. However, any of
4829+the following unit identifiers can be used: `px`, `cm`, `mm`, `in`, `inch`
4830+and `%`. There must not be any spaces between the number and the unit.
4834+{ width=50% }
4837+- Dimensions may be converted to a form that is compatible with
4838+ the output format (for example, dimensions given in pixels will
4839+ be converted to inches when converting HTML to LaTeX). Conversion
4840+ between pixels and physical measurements is affected by the
4841+ `--dpi` option (by default, 96 dpi is assumed, unless the image
4842+ itself contains dpi information).
4843+- The `%` unit is generally relative to some available space.
4844+ For example the above example will render to the following.
4845+ - HTML: `<img href="file.jpg" style="width: 50%;" />`
4846+ - LaTeX: `\includegraphics[width=0.5\textwidth,height=\textheight]{file.jpg}`
4847+ (If you're using a custom template, you need to configure `graphicx`
4848+ as in the default template.)
4849+ - ConTeXt: `\externalfigure[file.jpg][width=0.5\textwidth]`
4850+- Some output formats have a notion of a class
4851+ ([ConTeXt](https://wiki.contextgarden.net/Using_Graphics#Multiple_Image_Settings))
4852+ or a unique identifier (LaTeX `\caption`), or both (HTML).
4853+- When no `width` or `height` attributes are specified, the fallback
4854+ is to look at the image resolution and the dpi metadata embedded in
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:
4865+#### Extension: `fenced_divs` ####
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.
4881+ ::::: {#special .sidebar}
4882+ Here is a paragraph.
4887+Fenced divs can be nested. Opening fences are distinguished
4888+because they *must* have attributes:
4894+ This is a warning within a warning.
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
4902+lengths to distinguish nested divs from their parents.

4950+Inline footnotes are also allowed (though, unlike regular notes,
4951+they cannot contain multiple paragraphs). The syntax is as follows:
4953+ Here is an inline note.^[Inlines notes are easier to write, since
4954+ you don't have to pick an identifier and move down to type the
4957+Inline and regular footnotes may be mixed freely.
4961+#### Extension: `citations` ####
4963+To cite a bibliographic item with an identifier foo, use the
4964+syntax `@foo`. Normal citations should be included in square
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
4978+ [^1]: John Doe, "Frogs," *Journal of Amphibians* 44 (1999);
4979+ Susan Smith, "Flies," *Journal of Insects* (2000);
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` ####
3191−#### Extension: `shortcut_reference_links` ####
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.
3193−In a *shortcut* reference link, the second pair of brackets may
5136+#### Extension: `angle_brackets_escapable` ####
3194−be omitted entirely:
3196− See [my website].
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`.

3476−These files are specified using the `--csl` option or the `csl` metadata field.
3477−By default, `pandoc-citeproc` will use the [Chicago Manual of Style] author-date

3480−To make your citations hyperlinks to the corresponding bibliography
3481−entries, add `link-citations: true` to your YAML metadata.
3483−Citations go inside square brackets and are separated by semicolons.
3484−Each citation must have a key, composed of '@' + the citation
3485−identifier from the database, and may optionally have a prefix,
3486−a locator, and a suffix. The citation key must begin with a letter, digit,
3487−or `_`, and may contain alphanumerics, `_`, and internal punctuation

5960+For the same image on every slide, use the configuration

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.)

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.
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).
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`.
5981+To add a background image to the automatically generated title slide, use the
