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 Hilfe: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}}
.
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 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 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.
Examples
Markup | Renders as |
---|---|
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 w:en:equals sign, such as 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| {{Th|กรุงเทพมหานคร}} }} |
'"`UNIQ--templatestyles-0000002B-QINU`"'<span class="voy-foreign-lang voy-foreign-lang-th voy-foreign-dir-ltr"><span class="voy-lang voy-lang-th " lang="th" xml:lang="th" dir="ltr" title="Text auf thailändisch">กรุงเทพมหานคร</span></span> |
The above example shows the HTML rendered by the citation template, including the hidden metadata.
