Dependency on variable in parent scope (Build-PSBuildUpdatableHelp)

[IMJLA]

Expected Behavior

The following command should successfully complete its call to New-ExternalHelpCab:

Build-PSBuildUpdatableHelp -DocsPath 'C:\Temp\docs' -OutputPath 'C:\Temp\dist\UpdatableHelp'

Current Behavior

Currently an error is thrown if the $ModuleName variable is not correctly defined in the parent scope:

 New-ExternalHelpCab: untitled:Untitled-2:49:29
Line |
  49 |          New-ExternalHelpCab @cabParams > $null
     |                              ~~~~~~~~~~
     | Cannot validate argument on parameter 'LandingPagePath'. Path 'C:\Temp\docs/en-US/.md' is not a file.

Possible Solution

This can be addressed by adding a Module parameter that defaults to the value of the $ModuleName variable

Steps to Reproduce (for bugs)

1. Launch pwsh
2. Run this command:

Build-PSBuildUpdatableHelp -DocsPath 'C:\Temp\docs' -OutputPath 'C:\Temp\dist\UpdatableHelp'

Context

This will make it easier to use Build-PSBuildUpdatableHelp in custom psake tasks
