Template:Escape
This template uses Lua: |
Usage
editWhile primarily intended for use by other Lua modules, it can provide an alternative to multiple <nowiki>...</nowiki>
tags when part of the desire output should be executed.
For example, {{demo}} normally requires the demonstrated template to be wrapped in <nowiki>...</nowiki>
. However, you may want part of the value to be shown in the 'pre' tag to be processed before it reaches {{demo}}, such as in the example below where the result of {{#invoke:Escape/testcases|test_string2}}
is shown inside the <pre>...</pre>
tags.
Code | Result |
---|---|
{{demo
|<!--not escaped: -->{{escape | mode = kill
| char=;
| {*{#invoke:Escape ; main ; mode {{=}} kill ;
<!--unescaped:-->{{#invoke:Escape/testcases|test_string2}}<br>; { }*}
| *
| {{!}} }}
}}
|
{{#invoke:Escape | main | mode = kill |
test { test {\{ test, \test, \{,test\ \ \ {\<br>| { }}
|
Note how the *
character, used to break up the {{
to prevent execution, is removed and how the ;
character is replaced by |
.
Non-execution
editAfter removal of the escape chars, the returned text is inert; i.e. not executed even without <pre>...</pre>
. (The above example is executed only because {{demo}} forces execution.)
For example, setting |mode=kill
with \{\{done\}\
} as the first parameter and nothing else will simply cause the default escape character \
to be removed:
{{done}}
