Template:Repeat

The following documentation is located at Template:Repeat/doc. [<Edit> Template:Repeat/doc]
[⧼Purge⧽ Template:Repeat]

The {{repeat}} typing-aid template repeats a given character string a specified number of times.

Usage

{{repeat|nonnegative integer count|character string}}

where

• 1^st argument: nonnegative integer count (required);
• 2^nd argument: character string to repeat (default is ∗, i.e. &lowast;).

Note: The MediaWiki parser always ignore initial and final whitespace (spaces, tabs, newlines) in template arguments. (So {{repeat|10|ab }} is the same as {{repeat|10|ab}}.)

Tests

The code

-----

yields (interpreted by MediaWiki as an "horizontal rule" (<hr />)

---

The code

{{repeat|5|-}}

yields (NOT interpreted)

​-----

The code

*****

yields (* is interpreted by MediaWiki as a "list item" (<li>...</li>) (preceded by a bullet) of an unordered list)

The code

{{repeat|5|*}}

yields (using a low asterisk ∗ ∗ instead of an asterisk * * to avoid the MediaWiki interpretation of * as a "list item" (<li>...</li>) (preceded by a bullet) of an unordered list)

∗∗∗∗∗

Code

Uses {{~Repeat~1}} and {{~Repeat~0}}.

Note that ∗ as default value for second argument is given by the ∗ named character entity.

<noinclude>{{documentation}}<!--

 Put a null space {{sp|0}} before - (hyphen) to prevent the MediaWiki interpretation (when at beginning of a line) as an "horizontal rule" (<hr />).

 Replace * (asterisk) by &lowast; because MediaWiki interprets * as a "list item" (<li>...</li>) (preceded with a bullet) for an unordered list.
