Template:Escape

Template documentation[view] [edit] [history] [purge]

Usage

While primarily intended for use by other Lua modules, it can provide an alternative to multiple <nowiki>...</nowiki> tags when part of the desired 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\ \ \ {\ | { }} test test { test, test, {,test

Note how the * character, used to break up the {{ to prevent execution, is removed and how the ; character is replaced by |.

Non-execution

After 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}}
