Wraps a short span of text in <syntaxhighlight> tags (see mw:Extension:SyntaxHighlight GeSHi). This template should be used for short samples; longer content should use <pre>...</pre> or <syntaxhighlight>...</syntaxhighlight>. See Help:Wiki markup for an explanation of what the various tags do.[clarification needed]

If the content includes an equals sign (=), you must specify the parameter explicitly: {{code|1=date=30 Feb 2010}}.

The template uses the <syntaxhighlight> tag with the attribute enclose="none". This works like the combination of the <code> and <nowiki> tags, applied to the expanded wikitext. For example, {{code|some '''wiki''' text}} will not render the word "wiki" in bold, and will render the tripled-single-quotes:

some '''wiki''' text

However, {{code|a {{template}} call}} will still invoke the template:

a &#123;&#123;[[Template:{{{1}}}|{{{1}}}]]&#125;&#125; call

Use <nowiki>...</nowiki> around the template name to avoid this problem:

a {{template}} call

When used inline with regular text, {{code}} generally looks best and is easiest to read when it is explicitly spaced apart from the regular text:

foo &nbsp;{{code|bar baz}}&nbsp; quux.

is well spaced:

foo  bar baz  quux.


foo {{code|bar baz}} quux.

which is going to be visually confusing for many:

foo bar baz quux.

because "foo" and "bar" will seem more closely associated than "bar" and "baz"; the width of the space character in a monospaced font is almost always larger than in a proportional font.

Use parameter {{{2}}} (unnamed, as |2=, or more explicitly as |lang=) to specify a language for mw:Extension:SyntaxHighlight GeSHi. This option defaults to plain-text, i.e. no highlighting. There is no highlighting option for wikitext as a markup language, though html4strict and html5 are valid values, as are php, perl, css, javascript, mysql and many others. Attempting to use an invalid one causes a list of valid ones to be displayed in place of the template output, when the page is previewed or saved.

This template does not need to be substituted.

The declaration {{code |lang=cpp |int foo(const std::string& bar, const std::vector<long double*>& baz);}} is the prototype for a function defined later.

If the code contains an [[equals sign]], such as {{code |lang=javascript |code=var img = document.getElementsByTagName("img");}}, you must identify the first parameter explicitly as {{{1}}} or {{{code}}}; see also [[:bugzilla:5138]].

Included templates

Embedded templates do not function as expected inside {{code}}; for longer, free-form blocks of code, which can contain templates such as {{var}} and {{samp}}, use <code>...</code> as a wrapper instead of this template.

Templates used inside {{code}} expose the rendered HTML— this can be useful. For example:

Markup Renders as
{{cite web |title=Title |url=http://example.org}}
<span class="citation web">[http://example.org "Title"].</span><span title="ctx_ver=Z39.88-2004&rfr_id=info%3Asid%2Fwiki.wcpl.info%3ATemplate%3ACode%2Fdoc&rft.btitle=Title&rft.genre=book&rft_id=http%3A%2F%2Fexample.org&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Abook" class="Z3988"><span style="display:none;">&nbsp;</span></span>

The above example shows the HTML rendered by the citation template, including the hidden metadata.

{{em}} mild semantic emphasis As per {{strong}} but for the milder <em> emphasis (instead of / as well as typographical italicization).
{{var}} strIllustratePrefix To indicate text is a variable name. Use for any variables except those whose names include "I" (uppercase i) and/or "l" (lowercase L), where {{varserif}} below should be used instead to ensure a distinction between these letters is noticeable.
