Call a function in another script when executing using 'Run With PowerShell'

Question

I have functions in a \'library\' file to be called from my \'worker\' script.

Library File

function ShowMessage($AValue)
{
  $a = new-         


        

Answer 1

In your worker file, dot-source the library file, this will load all content (functions, variables, etc) to the global scope, and then you'll be able to call functions from the library file.

=================== Worker file ==========================
# dot-source library script
# notice that you need to have a space 
# between the dot and the path of the script
. c:\library.ps1

ShowMessage -AValue Hello
=================== End Worker file ======================

Answer 2

In the worker file change to this:

. "c:\scratch\b.ps1"

ShowMessage "Hello"

As @RoiDanton mentioned below:

Attention when using relative pathing: Don't forget to prepend a dot before the path . ".\b.ps1".

The first dot is an operator used to modify the scope and in that context it has nothing to do with paths. See Dot Source Notation.
