How do I dynamically create functions that are accessible in a parent scope?

Question

Here is an example:

function ChildF()
{
  #Creating new function dynamically
  $DynFEx =
@\"
  function DynF()
  {
    \"Hello DynF\"
  }
\"@
  Invoke-Expres         


        

Answer 1

A more correct and functional way to do this would be to return the function body as a script block and then recompose it.

function ChildF() {
    function DynF() {
        "Hello DynF"
    }
    return ${function:DynF}
}
$DynFEx = ChildF
Invoke-Expression -Command "function DynF { $DynFEx }"
DynF
