 | This is a documentation subpage for Template:Code It may contain 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: Template:Tji.
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, Template:Tji will not render the word "wiki" in bold, and will render the tripled-single-quotes:
some '''wiki''' text
If the above example is declared as wikitext (via Template:Tji, the output is rendered as follows:
some '''wiki''' text
However, Template:Tji 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 bazquux.
versus:
foo {{code|bar baz}} quux.
which is less visually clear:
- 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. This option defaults to |lang=text, i.e. no highlighting. Valid values include |lang=wikitext for wikitext, |lang=html for HTML, along with many other languages including php, perl, css, javascript, mysql. Attempting to use an invalid value for lang will cause the page to be added to :Category:Pages with syntax highlighting errors, and no syntax highlighting will be present in the output. html4strict and html5 used to be valid values - however, |lang=html should be used instead.
This template does not need to be substituted.
Examples
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:
The above example shows the HTML rendered by the citation template, including the hidden metadata.
Expensive Parser Function warning
This template internally uses mw:Extension:SyntaxHighlight, which is considered an 'expensive parser function' (see WP:EXPENSIVE). If used on a page which uses more than 500 expensive parser functions, the output of subsequent uses of this template will be presented using <code>...</code> formatting (without any syntax highlighting) instead.
