How to get the current directory of the cmdlet being executed

Most answers don't work when debugging in the following IDEs:

• PS-ISE (PowerShell ISE)
• VS Code (Visual Studio Code)

Because in those the $PSScriptRoot is empty and Resolve-Path .\ (and similars) will result in incorrect paths.

Freakydinde's answer is the only one that resolves those situations, so I up-voted that, but I don't think the Set-Location in that answer is really what is desired. So I fixed that and made the code a little clearer:

$directorypath = if ($PSScriptRoot) { $PSScriptRoot } `
    elseif ($psise) { split-path $psise.CurrentFile.FullPath } `
    elseif ($psEditor) { split-path $psEditor.GetEditorContext().CurrentFile.Path }
