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/testniprimeri|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/testniprimeri|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}}

Examples

Original:

test { test {\{ test, \test, \{,test\ \ \ {\

Using internal method to remove {:

{{escape|mode=kill|test { test {\{ test, \test, \{,test\ \ \ {\|{}}

test test { test, test, {,test \

Using {{replace}} to remove {:

{{escape|mode=undo|{{replace|{{escape|mode=text|test { test {\{ test, \test, \{,test\ \ \ {\}}|{|}}}}

test test { test, test, {,test \

No removal of { between escape/unescape (escape char not restored):

{{escape|mode=undo
|{{escape|mode=text|test { test {\{ test, \test, \{,test\ \ \ {\}}
}}

test { test {{ test, test, {,test {\

Restore to original after escape

{{escape|mode=undo
|{{escape|mode=text|test { test {\{ test, \test, \{,test\ \ \ {\}}
|\
}}

test { test {\{ test, \test, \{,test\ \ \ {\

Remove the word test if not escaped and then place a different escape char in the place of the old escape char (for use by something else):

Note: The '%' char is a special in Lua, so use '%%' if that is the desired replacement. Otherwise, just a single char is fine (or a word).

{{escape|mode=kill
|test { test {\{ test, \test, \{,test\ \ \ {\
|test
|%%
}}

{ {%{ , %test, %{,% % % {\
