Is there a way to retrieve a PowerShell function name from within a function?

You can use $MyInvocation which contains some useful information about what is currently executed.

function foo {    'This function is called {0}.' -f $MyInvocation.MyCommand}

When you are in a function you can access the automatic variable $PSCmdLet.

This is an extremely useful variable that holds a lot of information about the currently executing cmdlet.

In our scenario we wanted the name and the definition of the current function for some recursion. $MyInvocation was null because the function was within a PowerShell module.

However, there is a "MyInvocation" property on the PSCmdLet object which contains all the information needed and allowed our scenario to run.

e.g. $PSCmdlet.MyInvocation.MyCommand.Name = The name of the function$PSCmdlet.MyInvocation.MyCommand.Definition = The definition of the function

Easy.

function Get-FunctionName ([int]$StackNumber = 1) {    return [string]$(Get-PSCallStack)[$StackNumber].FunctionName}

By default Get-FunctionName in the example will get the name of the function that called it.

Function get-foo () {    Get-FunctionName}get-foo#Reutrns 'get-foo'

Increasing the StackNumber parameter will get the name of the next function call up.

Function get-foo () {    Get-FunctionName -StackNumber 2}Function get-Bar  () {    get-foo }get-Bar #Reutrns 'get-Bar'
