1922−

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:
1928−
1929−```
1930−${ styles.html() }
1931−```
1932−
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.)
1937−
1938−Partials may optionally be applied to variables using

1947−If `articles` is an array, this will iterate over its

1952−${ for(articles) }
1953−${ it:bibentry() }
1954−${ endfor }
1955−```
1956−
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`.
1961−
1962−Final newlines are omitted from included partials.
1963−
1964−Partials may include other partials.

1976−The separator in this case is literal and (unlike with `sep`
1977−in an explicit `for` loop) cannot contain interpolated

1980−### Nesting
1981−
1982−To ensure that content is "nested," that is, subsequent lines

1985−```
1986−$item.number$ $^$$item.description$ ($item.price$)

1988−
1989−In this example, if `item.description` has multiple lines,
1990−they will all be indented to line up with the first line:

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:

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

2019−
2020−Normally, spaces in the template itself (as opposed to values of

1964+Using variables in templates
1965+----------------------------
1966+
1967+Variable names are sequences of alphanumerics, `-`, and `_`,
1968+starting with a letter. A variable name surrounded by `$` signs
1969+will be replaced by its value. For example, the string `$title$` in
1970+
1971+ <title>$title$</title>
1972+
1973+will be replaced by the document title.
1974+
1975+To write a literal `$` in a template, use `$$`.
1976+
1977+Templates may contain conditionals. The syntax is as follows:
1978+
1979+ $if(variable)$
1980+ X
1981+ $else$
1982+ Y
1983+ $endif$
1984+
1985+This will include `X` in the template if `variable` has a truthy
1986+value; otherwise it will include `Y`. Here a truthy value is any
1987+of the following:
1988+
1989+- a string that is not entirely white space,
1990+- a non-empty array where the first value is truthy,
1991+- any number (including zero),
1992+- any object,
1993+- the boolean `true` (to specify the boolean `true`
1994+ value using YAML metadata or the `--metadata` flag,
1995+ use `true`, `True`, or `TRUE`; with the `--variable`
1996+ flag, simply omit a value for the variable, e.g.
1997+ `--variable draft`).
1998+
1999+`X` and `Y` are placeholders for any valid template text,
2000+and may include interpolated variables or other conditionals.
2001+The `$else$` section may be omitted.
2002+
2003+When variables can have multiple values (for example, `author` in
2004+a multi-author document), you can use the `$for$` keyword:
2005+
2006+ $for(author)$
2007+ <meta name="author" content="$author$" />
2008+ $endfor$
2009+
2010+You can optionally specify a separator to be used between
2011+consecutive items:
2012+
2013+ $for(author)$$author$$sep$, $endfor$
2014+
2015+Note that the separator needs to be specified immediately before the `$endfor`
2016+keyword.
2017+
2018+A dot can be used to select a field of a variable that takes
2019+an object as its value. So, for example:
2020+
2021+ $author.name$ ($author.affiliation$)
2022+
2023+The value of a variable will be indented to the same level as the variable.
2024+
2025+If you use custom templates, you may need to revise them as pandoc
2026+changes. We recommend tracking the changes in the default templates,
2027+and modifying your custom templates accordingly. An easy way to do this
2028+is to fork the [pandoc-templates] repository and merge in changes after each
2029+pandoc release.
2030+
2031+Templates may contain comments: anything on a line after `$--`
2032+will be treated as a comment and ignored.

4325+For LaTeX output, you can also use [`natbib`] or [`biblatex`] to
4326+render the bibliography. In order to do so, specify bibliography
4327+files as outlined above, and add `--natbib` or `--biblatex`
4328+argument to `pandoc` invocation. Bear in mind that bibliography

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

5436− as English: `american`, `british`, `canadian`, `english`,
5437− `australian`, `newzealand`, `USenglish`, or `UKenglish`.)
5438−
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:
5442−
5443− title = {My Dinner with {Andre}}

5445− - In addition, words that should remain lowercase (or camelCase)
5446− should be protected:
5447−
5448− title = {Spin Wave Dispersion on the {nm} Scale}
5449−
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.
5454−
5455−If you are using a CSL bibliography (either JSON or YAML), then observe
5456−the following rules:
5457−
5458− - All titles should be in sentence case.
5459−
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.)
5463−
5464− - Protect words that should not be converted to title case using

5467− Spin wave dispersion on the <span class="nocase">nm</span> scale

5472−`inproceedings` (which will be mapped to CSL `paper-conference`).
5473−
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`

5493−These files are specified using the `--csl` option or the `csl`

5520−
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,

5532−after the period, depending on the setting of
5533−`notes-after-punctuation`, as described below in [Other relevant
5534−metadata fields].
5535−
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

5574−
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)

5579−
5580− last paragraph...

5584−The bibliography will be inserted after this heading. Note that

5588−## Including uncited items in the bibliography
5589−
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:
5593−

5595− nocite: |
5596− @item1, @item2
5597− ...
5598−
5599− @item3
5600−
5601−In this example, the document will contain a citation for `item3`
5602−only, but the bibliography will contain entries for `item1`, `item2`, and
5603−`item3`.
5604−

5610− @*
5611− ...
5612−
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

5627− (for author-date and numerical styles only).
5628−
5629−`lang`
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.)
5635−
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:
5640−
5641− - `zh-u-co-pinyin` -- Chinese with the Pinyin collation.
5642− - `es-u-co-trad` -- Spanish with the traditional collation
5643− (with `Ch` sorting after `C`).
5644− - `fr-u-kb` -- French with "backwards" accent sorting
5645− (with `coté` sorting after `côte`).
5646− - `en-US-u-kf-upper` -- English with uppercase letters sorting
5647− before lower (default is lower before upper).
5648−
5649−`notes-after-punctuation`
5650−: If true (the default), pandoc will put footnote citations
5651− after following punctuation. For example, if the source
5652− contains `blah blah [@jones99].`, the result will look like
5653− `blah blah.[^1]`, with the note moved after the period and
5654− the space collapsed. If false, the space will still be
