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:Template]] 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 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 mw: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.
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:
The above example shows the HTML rendered by the citation template, including the hidden metadata.
TemplateData
This is the TemplateData for this template used by TemplateWizard, VisualEditor and other tools. Click here to see a monthly parameter usage report for this template in articles based on this TemplateData.
To indicate text is a variable name. Use for any variable names except those including "I" (uppercase i) and/or "l" (lowercase L); for these, Template:Braces should be used to ensure a noticeable distinction
To display parameters as used in code (i.e. with triple braces), especially to indicate relationships between them. May be combined with Template:Braces above
To display parameter values lightly bordered; replaces <code>...</code>, especially when value contains embedded or leading/trailing blanks; visualized here with middot (·) but can use ␠, ▯, or any character.
To showcase with colors in horizontal format the syntax of any template, while providing an easy way to display placeholder texts using colons as separators
To indicate text is source code. To nest other templates within Template:Braces, use <code>...</code>. {{codett}} differs only in styling: someMethod becomes Template:Codett
To showcase with colors and multiple lines (vertical format) the syntax of any template, while providing an easy way to display placeholder texts using colons as separators
