How to hide "Helper" Functions in Powershell Modules

Question

I have a module xy which has several functions for the end user and several internal helper functions called by functions but not by the end user.

Get-Command -Module xy -CommandType function 

lists all functions I have in my module folder (e.g. get-foo and get-foo_helper)

Is there a way to hide get-foo_helper function from the end user who is using:

Get-Command -Module tcaps -CommandType function 

Answer 1

One thing I have done is use the verb-noun naming convention for functions I want to export, but leave out the hyphen in helper functions.

Then, export-modulemember *-* takes care of only exporting what you want to export.
