A template is a piece of predefined wikitext that can be inserted into an article. Templates are primarily used to aid in formatting content.

Usage

Templates are used by adding the following markup to an article:

{{Template name}}

The general format is:

parameter_1parameter_2…parameter_N

See #List of templates for specific usage instructions.

Most templates take additional arguments, such as Template:Note:

{{Note|This text should be noted.}}

which produces:

This text should be noted.

Some templates can use named parameters, such as Template:hc:

{{hc|head=/etc/machine-id|output=0123456789abcdeffedcba9876543210}}

which produces:

0123456789abcdeffedcba9876543210
/etc/machine-id

Style

  • Templates must be used with capitalization shown in the examples on their pages—for example, {{Pkg|…}} and {{ic|…}} are correct, while {{pkg|…}} and {{Ic|…}} are not.

  • There must be no spaces around a template name—for example, {{Template name|…}} is correct, while {{ Template name |…}} is not.

  • Templates must not be categorized.

Escape template-breaking characters

There are some characters that, if used inside a template, will break its output: most frequently this happens with (the equal sign) and (the pipe sign). Solutions to this problem are described below.

* The pipe symbol () can be escaped using the {{!}} magic word. * The equal sign () can be escaped using the {{=}} magic word.

Named and numbered parameters

If the problem is only with signs, the recommended solution is to explicitly introduce template parameters with their positional numbers or names.

Example:

{{Tip|1=https://archlinux.org/?foo=bar}}

Result:

https://archlinux.org/?foo=bar

This is very useful for:

  • variable definitions,

  • external links with query strings in URLs,

  • shell strings and commands,

  • lines of code.

White space characters—e.g. newlines—are automatically stripped from the beginnings and ends of named parameter values. To preserve white space characters, start the parameter value with a <nowiki/> tag.

Example:


{{Tip|1=<nowiki/>
* https://archlinux.org/?foo=bar
* https://archlinux.org/?foo=baz
}}

Result:

* https://archlinux.org/?foo=bar * https://archlinux.org/?foo=baz

Multiple parameters

  • Using positional parameters 1 and 2.

  • Example:

{{hc|1=$ echo "="|2==}}

  1. Result:

=
$ echo "="

  • Using named parameters head and output.

  • Example:

{{hc|head=$ echo "="|output==}}

  1. Result:

=
$ echo "="

nowiki tags

If you are having problems with characters other than —e.g. }—the recommended solution is to enclose the whole parameter in <nowiki> tags. This method displays all kinds of characters, but completely prevents the wiki engine from processing text markup, such as links and other templates.

Example:

{{Tip|&lt;nowiki>= | }} https://archlinux.org/ {{ic|foo}}&lt;/nowiki>}}

Result:

Enclosing only specific parts (or even single characters) in <nowiki> tags still works of course, but for readability it is recommended to use such method only if links or other templates have to be normally displayed.

Example:

{{Tip|&lt;nowiki>= | }}&lt;/nowiki> https://archlinux.org/ {{ic|foo}}}}

Result:

https://archlinux.org/ foo

HTML entities

Replacing the offending characters with their respective HTML entities always works, but since it reduces the readability of the source text, it is recommended only when the solutions above are not practicable.

Example:

{{Tip|&amp;#61; &amp;#124; &amp;#123;&amp;#123; &amp;#125;&amp;#125;}}

Result:

&#61; &#124; &#123;&#123; &#125;&#125;

List of templates

The templates that users can use directly in articles on the ArchWiki are listed below.

For a list that also includes localization and meta templates, see:

* Do not experiment with existing templates. If you want to edit a non-protected template, copy the text to Template:Sandbox, edit and test it there, and copy it back when it works. See also #Testing. * It is strongly recommended—and is necessary for protected templates—to suggest any modifications on discussion pages first. See also #Template creation.

Note

For use in drafts on discussion pages only:

Status

These templates should be added at the beginning of concerning articles or sections. See also Help:Style#Article status templates.

Translators should also check template guidelines in ArchWiki:Translation Team.

The pages flagged with the article status templates are tracked in the corresponding maintenance category and in ArchWiki:Statistics#Maintenance statistics.

Table header

Table cell

You can use attributes with table cell templates by prefixing them, e.g: | colspan=2 {{Yes}}.

Text align

Cell background

Common text

Meta

These templates should only be transcluded from other templates.

Template creation

* Before creating a template, discuss the idea in Help talk:Template. * The Template namespace is semi-protected. Only autoconfirmed users can create or edit templates. * Only create relevant templates—if you are attempting to create a very specialized template that will likely only ever be used on a few articles, please do not bother, avoid cluttering up the templates namespace. * Only create concise templates—remember The Arch Way and Keep It Simple, Stupid!

The following template should be used when creating new templates to facilitate usage and editing:

<noinclude>
{{Template}}

A brief description of the template

== Usage ==

 &lt;nowiki&gt;{{Template name|param1|param2|...|paramN}}&lt;/nowiki&gt;

== Example ==

{{Template name|param1|param2|...|paramN}}</noinclude><includeonly>Template code goes here...</includeonly>

To begin the creation process, simply visit :Template:Template name (substituting Template name with the desired name of the template), edit, and add the relevant wikitext.
