rm completely unused id parameter to avoid duplicate blank ids on pages with multiple transclusions

New page

{{Documentation subpage}}

{{#ifeq: {{PAGENAME}}|{{ROOTPAGENAME}}|{{High-risk|24,000+}}}}
{{Expensive}}

==Usage==
Wraps a short span of text in <code><nowiki><syntaxhighlight></nowiki></code> tags (see [[mw:Extension:SyntaxHighlight]]). This template should be used for short samples; longer content should use {{tag|pre}} or {{tag|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: {{tji|code|2=1:int i = 0;}}.

The template uses the {{tag|syntaxhighlight|o}} tag with the attribute <code>inline=1</code>. This works like the combination of the {{tag|code|o}} and {{tag|nowiki|o}} tags, applied to the expanded wikitext. For example, {{tji|code|<nowiki>some '''wiki''' text</nowiki>}} will '''''not''''' render the word "wiki" in bold, and will render the tripled-single-quotes:

:{{code|some '''wiki''' text}}

If the above example is declared as wikitext (via {{tji|code|<nowiki>some '''wiki''' text</nowiki>|lang:wikitext}}, the output is rendered as follows:

:{{code|some '''wiki''' text|lang=wikitext}}

However, {{tji|code|<nowiki>a {{template}} call</nowiki>|lang:wikitext}} will still invoke the template:

:{{code|a {{template}} call|lang=wikitext}}

Use {{tag|nowiki}} around the template name to avoid this problem:

:{{code|a <nowiki>{{template}}</nowiki> call|lang=wikitext}}

When used inline with regular text, {{tnull|code}} generally looks best and is easiest to read when it is explicitly spaced apart from the regular text:
:{{code|foo  <nowiki>{{code|bar baz}}</nowiki>  quux.|lang=wikitext}}
is well spaced:
:foo  {{code|bar baz}}  quux.
versus:
:{{code|foo <nowiki>{{code|bar baz}}</nowiki> quux.|wikitext}}
which is less visually clear:
:foo {{code|bar baz}} quux.
because "foo" and "{{code|bar}}" will seem more closely associated than "{{code|bar}}" and "{{code|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 {{para|2}}, or more explicitly as {{para|lang}}) to specify a language for [[mw:Extension:SyntaxHighlight]]. This option defaults to {{para|lang|text}}, i.e. no highlighting. Valid values include {{para|lang|wikitext}} for wikitext, {{para|lang|html}} for HTML, along with many other languages including {{code|php}}, {{code|perl}}, {{code|css}}, {{code|javascript}}, {{code|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. {{code|html4strict}} and {{code|html5}} used to be valid values - however, {{para|lang|html}} should be used instead.

This template does not need to be [[Wikipedia:Template substitution|substituted]].

===Examples===

{{markup
|<nowiki>Lorem {{code|ipsum '''dolor'''}} sit amet</nowiki>
|Lorem {{code|ipsum '''dolor'''}} sit amet

|<nowiki>Lorem {{code|ipsum '''dolor'''|wikitext}} sit amet</nowiki>
|Lorem {{code|ipsum '''dolor'''|wikitext}} sit amet

|<nowiki>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.</nowiki>
|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.

|<nowiki>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]].</nowiki>
|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]].
}}

===Included templates===
Embedded templates do not function as expected inside {{tl|code}}; for longer, free-form blocks of code, which can contain templates such as {{tl|var}} and {{tl|samp}}, use {{tag|code}} as a wrapper instead of this template.

Templates used inside {{tl|code}} expose the rendered HTML— this can be useful. For example:
<div style="overflow:auto;">
{{markup
|1=<nowiki>{{code|
{{cite web |title=Title |url=http://example.org}}
|lang=html
}}</nowiki>
|2={{code|
{{cite web |title=Title |url=http://example.org}}
|lang=html
}}
}}
</div>
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 {{tag|code}} formatting (without any syntax highlighting) instead.

== TemplateData ==
{{Format TemplateData|<templatedata>

"description": "An inline source code string.",
"format": "inline",
"params": {
