Functions are usually defined with the [[Pragma: \function]]: Functions are usually defined with the [[Pragma: \function]]:
``` ```
\function my-function(parameter:"2") \function myfun(param:"2")

Functions can be invoked in several ways: Functions can be invoked in several ways:
* Directly transclude functions with the syntax `<<myfn param:"value">>` * Directly transclude functions with the syntax `<<myfun param:"value">>`
* Assign functions to widget attributes with the syntax `<div class=<<myfn param:"value">>>` * Assign functions to widget attributes with the syntax `<div class=<<myfun param:"value">>>`
* Invoke functions via the [[function Operator]] with the syntax `[function[myfn],[value],...]` * Invoke functions via the [[function Operator]] with the syntax `[function[myfun],[value],...]`
* Directly invoke functions whose names contain a period as custom filter operators with the syntax `[my.fn[value]]` or `[.myfn[value]]` * Directly invoke functions whose names contain a period as custom filter operators with the syntax `[my.fun[value]]` or `[.myfun[value]]`
