powershell indentation

Question

I\'m writing a large script that deploys an application. This script is based on several nested function calls.

Is there any way to \"ident\" the output based on the dep

Answer 1

You could use a wrapper function around write-host which used $MyInvocation to determine the stack depth to create a number of spaces to prefix the message.

Combine this with the -scope ‹n› parameter of Get-Variable to pull out each calling level… something like the showstack function adapted from Windows PowerShell In Action (Payette, 1^st Ed):

function ShowStack {
  trap { continue; }
  0..100 | Foreach-Object {
    (Get-Variable -scope $_ 'MyInvocation').Value.PositionMessage -replace "`n"
  }
}

You'll need the maximum value of $_ in the pipeline before Get-Variable fails for scope count being too high.
