Vorlage:Code/Doku

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-00000028-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.

Die semantischen Vorlagen dienen der Kennzeichnung von Text. Der Text wird in spezielle HTML-Tags eingebettet, die die Bedeutung des Inhalts kennzeichnen. Browser, Robots und Werkzeuge für Barrierefreiheit können entsprechend darauf reagieren. Folgende semantische Vorlagen können in Wikivoyage-Artikeln eingesetzt werden:

• {{em}} – Die Vorlage kennzeichnet Text, der besonders betont werden soll. Browser stellen ihn im Regelfall kursiv dar.
• {{strong}} – Dient der starken Hervorhebung von Wörtern und Passagen. Die Darstellung erfolgt standardmäßig in Fettschrift.

In Artikeln außerhalb des Haupt- und Nachrichtennamensraums (Diskusssionen, Projekt- und Hilfeseiten) können weitere Vorlagen Anwendung finden:

• {{strongbad}} – Wie {{strong}} aber rot wie in dem Beispiel: „Benutze {{strongbad}} niemals in Artikeln.“
• {{stronggood}} – Wie {{strongbad}} aber grün wie in dem Beispiel: „Benutze {{stronggood}} nur außerhalb des Artikelnamensraums.“
• {{var}} – Zusammen mit {{varserif}} dient die Vorlage der Kennzeichnung und Visualisierung von Variablen bzw. Platzhaltern in Dokumentationen und Hilfetexten.

Die folgenden Vorlagen stellen lediglich eine Formatierungshilfe dar, erzeugen aber keine speziellen [X]HTML-Tags, um Inhalte maschinenlesbar eine Bedeutung zu geben.

• {{wikivar}} – Stellt Text als Magisches Wort dar und erleichtert damit die Dokumentation und Erstellung von Hilfeseiten. Beispiele: {{PAGENAME}}, {{DEFAULTSORT:Lastname, Firstname}}.
• {{para}} – Dient der Ausgabe von Vorlagenparametern (|title=) oder Parametern mit Werten (|year=2008).
• {{tlx}} and related – For displaying entire templates (with or without parameters and values) as code.
• {{tag}} – For using HTML elements ("tags") in prose (e.g. "When coding HTML <img>...</img> tags, always include …").
• {{code}} – For computer source code (e.g. "always include the alt= parameter"). (Note: to nest other templates like {{var}} inside, use <code>...</code> instead of {{code}}.)
• {{syntaxhighlight}} or {{sxhl}} – Wrapper for <syntaxhighlight>...</syntaxhighlight>, but will wrap overflowing text.
• {{pre}} – For larger blocks of source code and other pre-formatted text.
• {{pre2}}, a template with similar functionality but induces optional line wrap and optional scroll bars.
• {{bq}} – For indented blocks of content, such as block quotations, examples, poems, etc.
• {{kbd}} – For indicating user input.
• {{key press}} – For indicating the input of specific keystrokes, e.g. ⎈ CtrlX.
• {{samp}} – For example output.
• <syntaxhighlight>
