Get parent function name

PowerShell Help
1

I have a script called x.ps1 which contains a function called Parent. This function calls another function called Child (which is located in a separate module).
In the Child function I want to retrieve the name of the script and the name of the parent function.
I can get the script name (Get-ChildItem $MyInvocation.PSCommandPath | Select -Expand Name).
I cannot find out how to get the name of the parent function from within the child function.

Thanks

I think you are going to have to pass it in as a parameter

Here’s an example:

cls
function parent {
    child $MyInvocation.MyCommand, "SomeOtherStuff"
}

function child {
    Param (
        [string]$PFunc,
        [string]$OtherParam
    )
    $PFunc
    $OtherParam
}

$a = parent
$a

You can use Get-PSCallStack since PowerShell v3 to access information about the parent function.

cls
function parent {
    child 
}

function child {
    $callStack = Get-PSCallStack
    if ($callStack.Count -gt 1) {
        'Parent function: {0}' -f $callStack[1].FunctionName
    }
}

parent

Ooo, nice tip Daniel. That’s good stuff right there.

Thanks Daniel - exactly what I needed :slight_smile:

This can also be done using the $MyInvocation variable by specifying the scope:

function child
{
    "Parent Function Name: $((Get-Variable MyInvocation -Scope 1).Value.MyCommand.Name)"
}

function parent
{
    child
}

parent

Scope 0 = Current Scope
Scope 1 = Parent Scope
