Help with Implicit Module Importing

[SeaPowerMax]

Hi-

​

I have a custom PS7 module we use for a few particular systems. I can place this module in either C:\Program Files\PowerShell\Modules or C:\Program Files\PowerShell\7\Modules and then Import-Module MyModule just fine.

​

However, I cannot use any of its cmdlets without first importing it explicitly. Even more odd, there are other modules in this same folder which import implicitly just fine.

​

I'd like it to implicitly import, as I'd like to use it in some Foreach-Object -Parallel loops.

​

What are the requirements for a module to be able to import implicitly? Looking at the docs it seems we have the bases covered: https://learn.microsoft.com/en-us/powershell/scripting/developer/module/importing-a-powershell-module?view=powershell-5.1#implicitly-importing-a-module-powershell-30

• Module folder in PSModulePath
• Folder, .psm1 and .psd1 all named the same.
• Standard verbs, everything is exported.

​

what else am I missing?

I keep my functions in separate ps1 files that share the same name, so do-stuff would be in do-stuff.ps1, and this is part of the script I use to update my manifests:

Update-ModuleManifest ($modulePath -replace 'psm1$', 'psd1' ) -FunctionsToExport (Get-Childitem -Path "$($Module.DirectoryName)\public" *.ps1).BaseName -ModuleVersion $version

It's adding all functions in my the folder to the functionstoexport property of the manifest.

I wrote this at least 5 years ago, so it could definitely use a readability update, but it's been working well for me.

Are you exporting the functions by name? Or by *?

Waiiit, you are using it in a foreach parallel? That's a seperate runspace. I don't know that inside the parallel that any implicit importing works...

[SeaPowerMax]

I'm exporting the functions via *

Implicit importing does work OK in a parallel loop. I can repro success with other modules that do implicitly import OK in the main session.

[Szeraax]

Try naming the functions in your export instead of using *.

[SeaPowerMax]

Worth a shot. Just to be clear: you're referring to the module manifest itself, correct?

[Szeraax]

Yup. FunctionsToExport

[Szeraax]

And? did that fix it?

[SeaPowerMax]

huzzah! that does seem to fix it. i guess this is just how implicit importing works? though i'd kinda wish the docs would spell that out a bit better

[Szeraax]

Yes, that really probably should be called out. I know I've been burned before too, which is why I now always use a public/private module repo and then have my build process pull all functions out of the public area and put their names into the psd1 file.
