{{Shared Template Warning}} {{high-risk}} {{used in system}} {{Module rating|release}} {{Module rating|protected}} This module provides a consistent interface for processing boolean or boolean-style string input. While Lua allows the  and   boolean values, wikicode templates can only express boolean values through strings such as "1", "0", "yes", "no", etc. This module processes these kinds of strings and turns them into boolean input for Lua to process. It also returns  values as , to allow for distinctions between   and. The module also accepts other Lua structures as input, i.e. booleans, numbers, tables, and functions. If it is passed input that it does not recognise as boolean or, it is possible to specify a default value to return.

Syntax
ist der Wert, der getestet werden soll. Boolean input or boolean-style input (see below) always evaluates to either  or , and   always evaluates to. Other values evaluate to.

Verwendung
First, load the module. Note that it can only be loaded from other Lua modules, not from normal wiki pages. For normal wiki pages you can use instead.

Some input values always return, and some always return. -Werte geben immer  aus.

String values are converted to lower case before they are matched:

You can specify a default value if  receives input other than that listed above. If you don't supply a default, the module will return  for these inputs.

Note that the blank string also functions this way:

Although the blank string usually evaluates to  in wikitext, it evaluates to   in Lua. This module prefers the Lua behaviour over the wikitext behaviour. If treating the blank string as  is important for your module, you will need to remove blank arguments at an earlier stage of processing.
