Demo:CodeWrapper

This page shows how to include some page in its original form, without passing through the MediaWiki parser. The main idea of why this example is important can be found in this article: A computable framework for accountable data assets.

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
}}

Use unstripNoWiki text

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

 {{#invoke:CodeWrapper| unstrip | {{:Demo:SwitchStatement7}}  }}

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

 any of 3–5

Use returnHTMLText function

One may also use Lua to attach marker (<syntaxhighlight lang=html>) and preprocess the textual content of the given input string: Original source code:

 {{#invoke:CodeWrapper| returnHTMLText | {{:Demo:SwitchStatement7}}  }}

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

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

Use luaSourceCodeText function

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

 {{#invoke:CodeWrapper| luaSourceCodeText | {{:Module:Banana}}  }}

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

 local p = {} --p stands for package

function p.hello( frame )
    --return "Hello, world!"
    return frame
end

return p

Use reverseResult Function

In fact, if one needs to string.reverse function of Lua library. One can do the following:

{{#invoke:CodeWrapper|returnHTMLText|{{#invoke:CodeWrapper|reverseResult|{{:Module:Banana}}}} }}

The rendered page segment looks like follows:

p nruter

dne
emarf nruter    
"!dlrow ,olleH" nruter--    
) emarf (olleh.p noitcnuf

egakcap rof sdnats p-- }{ = p lacol

Some configurable results

Wiki Source Code	Rendered Result
'''Wrapper wikicode or text''' {{#ifexpr: 3<5 | This expression is {{#expr: 0=0}} | This expression is evaluated to {{#expr: 9>9}} }} '''Wrapper wikicode'''.	Wrapper wikicode or text This expression is 1 Wrapper wikicode.
{{#ifexpr: 7=3 | {{#expr: 3+2=5}} RESULT | some text representing {{#expr: 1<1}} result }}	some text representing 0 result
