| 40px | This is a documentation subpage for Template:Code. It contains usage information, categories and other content that is not part of the original template page. |
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:
some '''wiki''' text
However, {{code|a {{template}} call}} will still invoke the template:
a {{[[Template:{{{1}}}|{{{1}}}]]}} 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 {{code|bar baz}} quux.
is well spaced:
- foo
bar bazquux.
versus:
foo {{code|bar baz}} 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 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 |
|---|---|
{{code|
{{cite web |title=Title |url=http://example.org}}
}}
|
|
The above example shows the HTML rendered by the citation template, including the hidden metadata.
