PS: Helper Functions

Description:

Helper functions are functions that are used in modules that are not meant to be used as a public function, but rather a “helper”. These go under the folder Private at the root of your module and you call them into scripts like:

   Begin
   {
      If (-not (Test-path "$PSScriptRoot\..\Private\helpers.psm1"))
      {
         Import-Module $PSScriptRoot\..\Private\helpers.psm1"
      }
   }

You place that in the Begin {} block of your functions to call helper functions. And because your modules root psm1 file ignores that directory, you never see these functions get imported when you do Import-Module yourModuleName.

To Resolve:

1. I have made a couple of these over the years but have since just placed these functions into my template since I don’t always distribute modules completely and instead usually prefer self-contained scripts.

2. Older helper function with logging functions

3. Older helper function with Event log logging functions
