1756−If you use custom templates, you may need to revise them as pandoc

1771−### Delimiters
1772−
1773−To mark variables and control structures in the template,
1774−either `$`...`$` or `${`...`}` may be used as delimiters.
1775−The styles may also be mixed in the same template, but the
1776−opening and closing delimiter must match in each case. The
1777−opening delimiter may be followed by one or more spaces
1778−or tabs, which will be ignored. The closing delimiter may

1784−### Interpolated variables
1785−
1786−A slot for an interpolated variable is a variable name surrounded
1787−by matched delimiters. Variable names must begin with a letter
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:
1791−
1792−```
1793−$foo$
1794−$foo.bar.baz$
1795−$foo_bar.baz-bim$
1796−$ foo $
1797−${foo}
1798−${foo.bar.baz}
1799−${foo_bar.baz-bim}
1800−${ foo }
1801−```
1802−
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.
1807−
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.
1815−
1816−### Conditionals
1817−
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:
1824−
1825−```
1826−$if(foo)$bar$endif$

1865−
1866−A for loop begins with `for(variable)` (enclosed in
1867−matched delimiters) and ends with `endfor` (enclosed in matched
1868−delimiters.
1869−
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
1874− the map.
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.
1877−
1878−Examples:
1879−
1880−```
1881−$for(foo)$$foo$$sep$, $endfor$
1882−

1895−
1896−You may optionally specify a separator between consecutive

1903−
1904−Instead of using `variable` inside the loop, the special

1913−### Partials
1914−
1915−Partials (subtemplates stored in different files) may be
1916−included by using the name of the partial, followed
1917−by `()`, for example:
1918−
1919−```
1920−${ styles() }
1921−```
1922−
1923−Partials will be sought in the directory containing
1924−the main template. The file name will be assumed to
1925−have the same extension as the main template if it
1926−lacks an extension. When calling the partial, the
1927−full name including file extension can also be used:
1928−
1929−```
1930−${ 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
1939−a colon:
1940−
1941−```
1942−${ date:fancy() }
1943−
1944−${ articles:bibentry() }
1945−```
1946−
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
1950−
1951−```
1952−${ for(articles) }
1953−${ it:bibentry() }
1954−${ endfor }
1955−```
1956−
1957−Note that the anaphoric keyword `it` must be used when
1958−iterating over partials. In the above examples,
1959−the `bibentry` partial should contain `it.title`
1960−(and so on) instead of `articles.title`.
1961−
1962−Final newlines are omitted from included partials.
1963−
1964−Partials may include other partials.
1965−
1966−A separator between values of an array may be specified
1967−in square brackets, immediately after the variable name
1968−or partial:
1969−
1970−```
1971−${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:

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

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

2031−
2032−A pipe transforms the value of a variable or partial. Pipes are

2014+Using variables in templates
2015+----------------------------
2016+
2017+Variable names are sequences of alphanumerics, `-`, and `_`,
2018+starting with a letter. A variable name surrounded by `$` signs
2019+will be replaced by its value. For example, the string `$title$` in
2020+
2021+ <title>$title$</title>
2022+
2023+will be replaced by the document title.
2024+
2025+To write a literal `$` in a template, use `$$`.
2026+
2027+Templates may contain conditionals. The syntax is as follows:
2028+
2029+ $if(variable)$
2030+ X
2031+ $else$
2032+ Y
2033+ $endif$
2034+
2035+This will include `X` in the template if `variable` has a truthy
2036+value; otherwise it will include `Y`. Here a truthy value is any
2037+of the following:
2038+
2039+- a string that is not entirely white space,
2040+- a non-empty array where the first value is truthy,
2041+- any number (including zero),
2042+- any object,
2043+- the boolean `true` (to specify the boolean `true`
2044+ value using YAML metadata or the `--metadata` flag,
2045+ use `true`, `True`, or `TRUE`; with the `--variable`
2046+ flag, simply omit a value for the variable, e.g.
2047+ `--variable draft`).
2048+
2049+`X` and `Y` are placeholders for any valid template text,
2050+and may include interpolated variables or other conditionals.
2051+The `$else$` section may be omitted.
2052+
2053+When variables can have multiple values (for example, `author` in
2054+a multi-author document), you can use the `$for$` keyword:
2055+
2056+ $for(author)$
2057+ <meta name="author" content="$author$" />
2058+ $endfor$
2059+
2060+You can optionally specify a separator to be used between
2061+consecutive items:
2062+
2063+ $for(author)$$author$$sep$, $endfor$
2064+
2065+Note that the separator needs to be specified immediately before the `$endfor`
2066+keyword.
2067+
2068+A dot can be used to select a field of a variable that takes
2069+an object as its value. So, for example:
2070+
2071+ $author.name$ ($author.affiliation$)
2072+
2073+The value of a variable will be indented to the same level as the variable.
2074+
2075+If you use custom templates, you may need to revise them as pandoc
2076+changes. We recommend tracking the changes in the default templates,
2077+and modifying your custom templates accordingly. An easy way to do this
2078+is to fork the [pandoc-templates] repository and merge in changes after each
2079+pandoc release.
2080+
2081+Templates may contain comments: anything on a line after `$--`
2082+will be treated as a comment and ignored.

5437− `australian`, `newzealand`, `USenglish`, or `UKenglish`.)
5438−
5439− - As is standard with bibtex/biblatex, proper names should be

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:

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

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.

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,
5527−
5528− Blah blah [@foo, p. 33].
5529−
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].
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

5588−## Including uncited items in the bibliography
5589−
5590−If you want to include items in the bibliography without actually

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−
5605−It is possible to create a bibliography with all the citations,

5609− nocite: |
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
5617−files have to be in either BibTeX (for `--natbib`)
5618−or BibLaTeX (for `--biblatex`) format.

5625−: If true, citations will be
5626− hyperlinked to the corresponding bibliography entries
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
