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

Check out this script http://poshcode.org/scripts/3386.html

If you load up that Write-Verbose wrapper, you can set $WriteHostAutoIndent = $true and then just call Write-Host and it will be indented based on stack depth. So given these functions as you defined them originally:

function myFn()
{
   Write-Host "Start of myfn"
   myFnNested
   Write-Host "End of myfn"
}
function myFnNested()
{
   Write-Host "Start of myFnNested"
   Write-Host "End of myFnNested"
}

With no changes, you can just dot-source a script file with that Write-Host wrapper function in it:

C:\PS> . C:\Users\Jaykul\Documents\WindowsPowerShell\PoshCode\3386.ps1

And then merely set the preference variable before you call your function:

C:\PS> $WriteHostAutoIndent = $true
C:\PS> myFn
  Start of myfn
    Start of myFnNested
    End of myFnNested
  End of myfn

Beautiful indented output, like magic ;-)
