Template:Code

​{{{1}}}​

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

Usage

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.Template:Clarify

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 #REDIRECT [[Template:Template link]] {| style="margin:0.5em; padding:0.5em; background:#FEE; border:1px solid #999;" |- | [[Image:Icono aviso borrar.png|60px|left]] | <big>'''This page has been nominated for speedy deletion.'''</big><br />The reason given is '''"G8"'''.If you disagree with its speedy deletion, please explain why on [[Poledišano ya Template:Code|its talk page]]. If this page obviously does not meet the criteria for speedy deletion, or you intend to fix it, please remove this notice, but do not remove this notice from a page that you have created yourself. <span class="plainlinks">''Administrators, remember to check [[Special:Whatlinkshere/Template:Code|if anything links here]] and [//nso.wikipedia.org/w/index.php?title=Template:Code&action=history the page history] ([//nso.wikipedia.org/w/index.php?title=Template:Code&diff=0 last edit]) before [//nso.wikipedia.org/w/index.php?title=Template:Code&action=delete deletion].''</span> |}[[Category:Candidates for speedy deletion]] call​

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

​a {{template}} call​

When used inline with regular text, Template:Tnull 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 baz​  quux.

versus:

​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 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.

Finally, embedded templates do not function inside Template:Tnull; 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.

Examples

input	output
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}}}; see also [[:bugzilla:5138]].	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}}}; see also bugzilla:5138.
