Get-ModuleCommand should (optionally?) look at Value in ExportedCommands

[Chris Hunt]

Is your feature request related to a problem? Please describe.
I have a module that uses a DefaultCommandPrefix to disambiguate from built-in cmdlet names. Get-ModuleCommand operates on the key which is the command name before applying the prefix. This causes it to query info on the built-in command versus my command.

Example:

DefaultCommandPrefix = 'my'
New-Service vs New-myService

I want info on New-myService

Describe the solution you'd like
If Key -ne Value, use Value in Get-ModuleCommand.ps1#L53

Describe alternatives you've considered
I don't see anywhere that DefaultCommandPrefix is exposed to the runtime so you can programmatically check.

I believe you could also always just use Value instead of Key.

Get-ModuleCommand

   ModuleName: myModule

Name                     Alias      Synopsis
----                     -----      --------
Get-Service              gsv        Gets the services on the computer.
New-Service                         Creates a new Windows service.
Remove-Service                      Removes a Windows service.
Set-Service                         Starts, stops, and suspends a service, and changes its properties.

After poking around ExportedCommands for a few minutes I can't track down what is generating the name with prefix. The prefix or prefixed name doesn't seem to be in CmdletInfo. Pesky FormatData.

[Jeff Hicks]

What version of PowerShell are you running this under? I modified a module to use a default prefix and this works in 5.1.

It also works in PS 7 if the module is loaded

But there is a problem if it isn't loaded.

But only in PowerShell 7. Windows PowerShell works fine.

[Chris Hunt]

Yeah, I'm running in 7.

[Jeff Hicks]

This looks like a PowerShell 7 bug with Get-Module. Investigating.

[Jeff Hicks]

Microsoft agrees that this is a bug in PowerShell 7. The workaround for us appears to be first import the module then run Get-ModuleCommand.

[Jeff Hicks]

This is still a bug in PowerShell 7.2.

[Jeff Hicks]

Is this still an issue for you? It has been a while since this was opened.

[Chris Hunt]

I'm not currently using this module. I can't say.

[Jeff Hicks]

I think I'm going to close the issue then. We can always re-open it or start anew.
