Calling function in a Parallel foreach loop

[sekou2331]

Wanted to know if I created 3 function and wanted to call them in a foreach Parallel loop is this possible? I have been searching and I dont see anyone trying to do this.

What code have you tried? There is no reason why you can't do this.

Cant seem to find any documentation on calling outside functions. Will write something and see if I can get it to work.

Code: Select all

1..10 | 
    Foreach-Object -Parallel {
        function test1{
            param($P1)
            Write-Host "Function One says $P1"
        }
        function test2{
            param($P1)
            Write-Host "Function Two says $(2 * $P1)"
        }
        test1 $_
        test2 $_
    }

So it looks like this is for PowerShell 7. I am on PowerShell 5. Can this be done with workflows? If so is it possible to use work flow with function?

[jvierra]

Yes. You can only use "ForEach -Parallel" with PS 7.

Workflows can contain functions and load modules.

[sekou2331]

But the function would have to be in the the workflow and can not be called from outside the workflow?

[jvierra]

Correct. The same is true for run spaces and jobs.
