Demo:CodeWrapper

This page shows how to include some page in its original form, without passing through the MediaWiki parser.

For example the following code segment {{:Demo:SwitchStatement7}} would render a a result like following:

{{#switch: {{#expr: 3+2*1}}
 | 1 = one
 | 2 = two
 | 3|4|5 = any of 3–5
 | 6 = six
 | 7 = {{uc:sEveN}} <!--lowercase-->
 | #default = other
}}

In fact, if one tries to transclude a MediaWiki page in its original textual form without having MediaWiki parser parsing and interpreting the wiki code. One can do the following:

{{#switch: {{#expr: 3+2*1}}
 | 1 = one
 | 2 = two
 | 3|4|5 = any of 3–5
 | 6 = six
 | 7 = {{uc:sEveN}} <!--lowercase-->
 | #default = other
}}

One may also use Lua to trim the textual content of the given input string: Original source code:

 {{#invoke:CodeWrapper|trimText| {{PAGENAME}}  }}

This MediaWiki code(wiki text) will be rendered as follow:
