Module:LuaVar

Basics - Capitalization of LuaVar and the function (example varDefine) is required.:

To define a variable without returning the value:

{{#invoke:LuaVar|varDefine
|name= Variable Name
|value= Value
}}

To define a variable and return the value:

{{#invoke:LuaVar|varDefineEcho
|name= Variable Name
|value= Value
}}

To retrieve the value of a variable. Will inform if the variable is not defined.

{{#invoke:LuaVar|var
|name= Variable Name
}}
