Template:Code
<code>{{nw|{{{1}}}}}</code>
 | This template is used on 35,000+ pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
Usage
Wraps a short span of text in <syntaxhighlight> tags (see mw:Extension:SyntaxHighlight). 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.
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 <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:
However, {{code|a {{template}} call}} will still invoke the template:
Use <nowiki>...</nowiki> around the template name to avoid this problem:
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:
is well spaced:
versus:
which is going to be visually confusing for many:
because "foo" and "(I am not watching this page, so please ping me if you want my attention.)" will seem more closely associated than "(I am not watching this page, so please ping me if you want my attention.)" and "(I am not watching this page, so please ping me if you want my attention.)"; 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 (I am not watching this page, so please ping me if you want my attention.) and (I am not watching this page, so please ping me if you want my attention.) are valid values, as are (I am not watching this page, so please ping me if you want my attention.), (I am not watching this page, so please ping me if you want my attention.), (I am not watching this page, so please ping me if you want my attention.), (I am not watching this page, so please ping me if you want my attention.), (I am not watching this page, so please ping me if you want my attention.) 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

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]].

If the code contains an equals sign, such as |
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 |
|---|---|
{{code|
{{cite web |title=Title |url=http://example.org}}
}}
|
|
The above example shows the HTML rendered by the citation template, including the hidden metadata.
