1786+A slot for an interpolated variable is a variable name surrounded

1788+and can contain letters, numbers, `_`, `-`, and `.`. The
1789+keywords `it`, `if`, `else`, `endif`, `for`, `sep`, and `endfor` may
1790+not be used as variable names. Examples:
1803+Variable names with periods are used to get at structured
1804+variable values. So, for example, `employee.salary` will return the
1805+value of the `salary` field of the object that is the value of
1806+the `employee` field.
1808+- If the value of the variable is simple value, it will be
1809+ rendered verbatim. (Note that no escaping is done;
1810+ the assumption is that the calling program will escape
1811+ the strings appropriately for the output format.)
1812+- If the value is a list, the values will be concatenated.
1813+- If the value is a map, the string `true` will be rendered.
1814+- Every other value will be rendered as the empty string.
1818+A conditional begins with `if(variable)` (enclosed in
1819+matched delimiters) and ends with `endif` (enclosed in matched
1820+delimiters). It may optionally contain an `else` (enclosed in
1821+matched delimiters). The `if` section is used if
1822+`variable` has a non-empty value, otherwise the `else`
1823+section is used (if present). Examples:

1888+ - ${ foo.bar.last }, ${ foo.bar.first }
1892+$it.name$: $it.office$
1896+You may optionally specify a separator between consecutive
1897+values using `sep` (enclosed in matched delimiters). The
1898+material between `sep` and the `endfor` is the separator.
1901+${ for(foo) }${ foo }${ sep }, ${ endfor }
1904+Instead of using `variable` inside the loop, the special
1905+anaphoric keyword `it` may be used.
1909+ - ${ it.last }, ${ it.first }
1915+Partials (subtemplates stored in different files) may be
1916+included by using the name of the partial, followed
1917+by `()`, for example:
1923+Partials will be sought in the directory containing
1924+the main template. The file name will be assumed to
1925+have the same extension as the main template if it
1926+lacks an extension. When calling the partial, the
1927+full name including file extension can also be used:
1933+(If a partial is not found in the directory of the
1934+template and the template path is given as a relative
1935+path, it will also be sought in the `templates`
1936+subdirectory of the user data directory.)
1938+Partials may optionally be applied to variables using
1944+${ articles:bibentry() }
1947+If `articles` is an array, this will iterate over its
1948+values, applying the partial `bibentry()` to each one. So the
1949+second example above is equivalent to
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`.
1962+Final newlines are omitted from included partials.
1964+Partials may include other partials.
1966+A separator between values of an array may be specified
1967+in square brackets, immediately after the variable name
1973+${articles:bibentry()[; ]$
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.
1982+To ensure that content is "nested," that is, subsequent lines
1983+indented, use the `^` directive:
1986+$item.number$ $^$$item.description$ ($item.price$)
1989+In this example, if `item.description` has multiple lines,
1990+they will all be indented to line up with the first line:
1993+00123 A fine bottle of 18-year old
1994+ Oban whiskey. ($148)
1997+To nest multiple lines to the same level, align them
1998+with the `^` directive in the template. For example:
2001+$item.number$ $^$$item.description$ ($item.price$)
2002+ (Available til $item.sellby$.)
2008+00123 A fine bottle of 18-year old
2009+ Oban whiskey. ($148)
2010+ (Available til March 30, 2020.)
2013+If a variable occurs by itself on a line, preceded by whitespace
2014+and not followed by further text or directives on the same line,
2015+and the variable's value contains multiple lines, it will be
2016+nested automatically.
2018+### Breakable spaces
2020+Normally, spaces in the template itself (as opposed to values of
2021+the interpolated variables) are not breakable, but they can be
2022+made breakable in part of the template by using the `~` keyword
2023+(ended with another `~`).
2026+$~$This long line may break if the document is rendered
2027+with a short line length.$~$
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:
2041+$for(metadata/pairs)$
2042+- $it.key$: $it.value$
2045+$employee:name()/uppercase$
2048+Pipes may be chained:
2051+$for(employees/pairs)$
2052+$it.key/alpha/uppercase$. $it.name$
2056+Some pipes take parameters:
2059+|----------------------|------------|
2061+$it.name.first/uppercase/left 20 "| "$$it.name.salary/right 10 " | " " |"$
2063+|----------------------|------------|
2066+Currently the following pipes are predefined:
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,
2073+- `uppercase`: Converts text to uppercase.
2075+- `lowercase`: Converts text to lowercase.
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.
2081+- `reverse`: Reverses a textual value or array,
2082+ and has no effect on other values.
2084+- `first`: Returns the first value of an array, if
2085+ applied to a non-empty array; otherwise returns
2086+ the original value.
2088+- `last`: Returns the last value of an array, if
2089+ applied to a non-empty array; otherwise returns
2090+ the original value.
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.
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.
2100+- `chomp`: Removes trailing newlines (and breakable space).
2102+- `nowrap`: Disables line wrapping on breakable spaces.
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`.
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`.
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.
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.
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.

5065example, `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

4511−=================================
5322+ pandoc --citeproc myinput.txt
5324+To use this feature, you will need to have
5326+- a document containing citations (see [Extension: `citations`]);
5327+- a source of bibliographic data: either an external bibliography
5328+ file or a list of `references` in the document's YAML metadata
5329+- optionally, a [CSL] citation style.
5331+## Specifying bibliographic data
5333+You can specify an external bibliography using the
5334+`bibliography` metadata field in a YAML metadata section or the
5335+`--bibliography` command line argument. If you want to use
5336+multiple bibliography files, you can supply multiple
5337+`--bibliography` arguments or set `bibliography` metadata field
5338+to YAML array. A bibliography may have any of these formats:
5340+ Format File extension
5341+ ------------ --------------
5347+Note that `.bib` can be used with both BibTeX and BibLaTeX files;
5348+use the extension `.bibtex` to force interpretation as BibTeX.
5350+In BibTeX and BibLaTeX databases, pandoc parses LaTeX markup
5351+inside fields such as `title`; in CSL YAML databases, pandoc
5352+Markdown; and in CSL JSON databases, an [HTML-like markup][CSL
5361+`<span style="font-variant:small-caps;">...</span>` or `<sc>...</sc>`
5370+`<span class="nocase">...</span>`
5371+: prevent a phrase from being capitalized as title case
5373+As an alternative to specifying a bibliography file using
5374+`--bibliography` or the YAML metadata field `bibliography`, you
5375+can include the citation data directly in the `references` field
5376+of the document's YAML metadata. The field should contain an
5377+array of YAML-encoded references, for example:
5381+ - type: article-journal
5382+ id: WatsonCrick1953
5393+ title: 'Molecular structure of nucleic acids: a structure for
5394+ deoxyribose nucleic acid'
5395+ title-short: Molecular structure of nucleic acids
5396+ container-title: Nature
5400+ DOI: 10.1038/171737a0
5401+ URL: https://www.nature.com/articles/171737a0
5405+If both an external bibliography and inline (YAML metadata)
5406+references are provided, both will be used. In case of
5407+conflicting `id`s, the inline references will take precedence.
5409+Note that `pandoc` can be used to produce such a YAML metadata
5410+section from a BibTeX, BibLaTeX, or CSL JSON bibliography:
5412+ pandoc chem.bib -s -f biblatex -t markdown
5413+ pandoc chem.json -s -f csljson -t markdown
5415+Indeed, `pandoc` can convert between any of these
5418+ pandoc chem.bib -s -f biblatex -t csljson
5419+ pandoc chem.yaml -s -f markdown -t biblatex
5421+Running pandoc on a bibliography file with the `--citeproc`
5422+option will create a formatted bibliography in the format
5425+ pandoc chem.bib -s --citeproc -o chem.html
5426+ pandoc chem.bib -s --citeproc -o chem.pdf
5428+### Capitalization in titles
5430+If you are using a bibtex or biblatex bibliography, then observe
5431+the following rules:
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`.)
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:
5443+ title = {My Dinner with {Andre}}
5445+ - In addition, words that should remain lowercase (or camelCase)
5446+ should be protected:
5448+ title = {Spin Wave Dispersion on the {nm} Scale}
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.
5455+If you are using a CSL bibliography (either JSON or YAML), then observe
5456+the following rules:
5458+ - All titles should be in sentence case.
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.)
5464+ - Protect words that should not be converted to title case using
5467+ Spin wave dispersion on the <span class="nocase">nm</span> scale
5469+### Conference Papers, Published vs. Unpublished
5471+For a formally published conference paper, use the biblatex entry type
5472+`inproceedings` (which will be mapped to CSL `paper-conference`).
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`).
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.
5489+## Specifying a citation style
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
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
5510+ "container-title": {
5511+ "Lloyd's Law Reports": "Lloyd's Rep",
5512+ "Estates Gazette": "EG",
5513+ "Scots Law Times": "SLT"
5519+## Citations in note styles
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
5528+ Blah blah [@foo, p. 33].
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
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:
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].
5546+## Raw content in a style
5548+To include raw content in a prefix, suffix, delimiter, or term,
5549+surround it with these tags indicating the format:
5551+ {{jats}}<ref>{{/jats}}
5553+Without the tags, the string will be interpreted as a string
5554+and escaped in the output, rather than being passed through raw.
5556+This feature allows stylesheets to be customized to give
5557+different output for different output formats. However,
5558+stylesheets customized in this way will not be usable
5559+by other CSL implementations.
5563+## Placement of the bibliography
5565+If the style calls for a list of works cited, it will be placed
5566+in a div with id `refs`, if one exists:
5571+Otherwise, it will be placed at the end of the document.
5572+Generation of the bibliography can be suppressed by setting
5573+`suppress-bibliography: true` in the YAML metadata.
5575+If you wish the bibliography to have a section heading, you can
5576+set `reference-section-title` in the metadata, or put the heading
5577+at the beginning of the div with id `refs` (if you are using it)
5578+or at the end of your document:
5584+The bibliography will be inserted after this heading. Note that
5585+the `unnumbered` class will be added to this heading, so that the
5586+section will not be numbered.
5588+## Including uncited items in the bibliography
5590+If you want to include items in the bibliography without actually
5591+citing them in the body text, you can define a dummy `nocite` metadata
5592+field and put the citations there:
5601+In this example, the document will contain a citation for `item3`
5602+only, but the bibliography will contain entries for `item1`, `item2`, and
5605+It is possible to create a bibliography with all the citations,
5606+whether or not they appear in the document, by using a wildcard:
5613+For LaTeX output, you can also use [`natbib`] or [`biblatex`] to
5614+render the bibliography. In order to do so, specify bibliography
5615+files as outlined above, and add `--natbib` or `--biblatex`
5616+argument to `pandoc` invocation. Bear in mind that bibliography
5617+files have to be in either BibTeX (for `--natbib`)
5618+or BibLaTeX (for `--biblatex`) format.
5620+## Other relevant metadata fields
5622+A few other metadata fields affect bibliography formatting:
5625+: If true, citations will be
5626+ hyperlinked to the corresponding bibliography entries
5627+ (for author-date and numerical styles only).
5630+: The `lang` field will affect how the style is localized,
5631+ for example in the translation of labels, the use
5632+ of quotation marks, and the way items are sorted.
5633+ (For backwards compatibility, `locale` may be used instead
5634+ of `lang`, but this use is deprecated.)
5636+ A BCP 47 language tag is expected: for example, `en`,
5637+ `de`, `en-US`, `fr-CA`, `ug-Cyrl`. The unicode extension
5638+ syntax (after `-u-`) may be used to specify options for
5639+ collation (sorting) more precisely. Here are some examples:
5641+ - `zh-u-co-pinyin` -- Chinese with the Pinyin collation.
5642+ - `es-u-co-trad` -- Spanish with the traditional collation
5643+ (with `Ch` sorting after `C`).
5644+ - `fr-u-kb` -- French with "backwards" accent sorting
5645+ (with `coté` sorting after `côte`).
5646+ - `en-US-u-kf-upper` -- English with uppercase letters sorting
5647+ before lower (default is lower before upper).
5649+`notes-after-punctuation`
5650+: If true (the default), pandoc will put footnote citations
5651+ after following punctuation. For example, if the source
5652+ contains `blah blah [@jones99].`, the result will look like
5653+ `blah blah.[^1]`, with the note moved after the period and
5654+ the space collapsed. If false, the space will still be
