Template:Code

<syntaxhighlight lang="text" enclose="none">​{{{1}}}​</syntaxhighlight>

Template documentation[view] [edit] [history] [purge]

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:

<syntaxhighlight lang="text" enclose="none">​some wiki text​</syntaxhighlight>

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

<syntaxhighlight lang="text" enclose="none">​a {{[[Template:{{{1}}}|{{{1}}}]]}} call​</syntaxhighlight>

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

<syntaxhighlight lang="text" enclose="none">​a {{template}} call​</syntaxhighlight>

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:

<syntaxhighlight lang="text" enclose="none">​foo  {{code|bar baz}}  quux.​</syntaxhighlight>

is well spaced:

foo  <syntaxhighlight lang="text" enclose="none">​bar baz​</syntaxhighlight>  quux.

versus:

<syntaxhighlight lang="text" enclose="none">​foo {{code|bar baz}} quux.​</syntaxhighlight>

which is going to be visually confusing for many:

foo <syntaxhighlight lang="text" enclose="none">​bar baz​</syntaxhighlight> quux.

because "foo" and "<syntaxhighlight lang="text" enclose="none">​bar​</syntaxhighlight>" will seem more closely associated than "<syntaxhighlight lang="text" enclose="none">​bar​</syntaxhighlight>" and "<syntaxhighlight lang="text" enclose="none">​baz​</syntaxhighlight>"; 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 <syntaxhighlight lang="text" enclose="none">​html4strict​</syntaxhighlight> and <syntaxhighlight lang="text" enclose="none">​html5​</syntaxhighlight> are valid values, as are <syntaxhighlight lang="text" enclose="none">​php​</syntaxhighlight>, <syntaxhighlight lang="text" enclose="none">​perl​</syntaxhighlight>, <syntaxhighlight lang="text" enclose="none">​css​</syntaxhighlight>, <syntaxhighlight lang="text" enclose="none">​javascript​</syntaxhighlight>, <syntaxhighlight lang="text" enclose="none">​mysql​</syntaxhighlight> 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 <syntaxhighlight lang="text" enclose="none">​ipsum dolor​</syntaxhighlight> 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 <syntaxhighlight lang="cpp" enclose="none">​int foo(const std::string& bar, const std::vector<long double*>& baz);​</syntaxhighlight> 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 <syntaxhighlight lang="javascript" enclose="none">​var img = document.getElementsByTagName("img");​</syntaxhighlight>, 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}} }}	<syntaxhighlight lang="text" enclose="none">​ "Title". ​</syntaxhighlight>

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