The template {{code}} wraps a short span of text in <syntaxhighlight> tags (see Extension SyntaxHighlight).
Usage
It 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.
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 inline=1. This works like the combination of the <code> and <wiki> 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 {{[[Template:Code/doc|Template:Code/doc]]}} call
Use <nowiki>…</nowiki> around the template name to avoid this problem:
a '"`UNIQ--nowiki-00000005-QINU`"' 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 '"`UNIQ--nowiki-00000007-QINU`"' quux.
is well spaced:
- foo
bar bazquux.
versus:
foo '"`UNIQ--nowiki-0000000A-QINU`"' quux.
which is going to be visually confusing for many:
- foo
bar bazquux.
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 Extension:SyntaxHighlight. 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.
Examples
| Markup | Renders as |
|---|---|
| Lorem {{code|ipsum '''dolor'''}} sit amet | Lorem ipsum '''dolor''' sit amet
|
| 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. | The declaration 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}}}. | If the code contains an equals sign, such as var img = document.getElementsByTagName("img");, you must identify the first parameter explicitly as {{{1}}} or {{{code}}}.

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.
