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

You can use Console.CursorLeft to set its position. Be aware that write-output will reset any custom location, so you need to reset it after each output. Here is a sample:

    $i = 0
    function Indent() {
        [console]::CursorLeft += 2
        $i = [console]::CursorLeft
        $i
    }

    function UnIndent() {
        if($i -gt 0) { $i -= 2 }
        [console]::CursorLeft = $i
        $i
    }

    function WriteIndent([string]$s) {
        [console]::CursorLeft += $i
        write-host $s
        # Reset indent, as write-host will set cursor to indent 0
        [console]::CursorLeft += $i
    }

    function myFnNested() {     
      $i = Indent     
      WriteIndent "Start of myFnNested"     
      WriteIndent "End of myFnNested"     
      $i = UnIndent 
    }

    function myFn() {     
      $i = Indent   
      WriteIndent "Start of myfn"     
      myFnNested
      WriteIndent "End of myfn"     
      $i = UnIndent 
    } 

    WriteIndent "Start of myscript"
    myFn
    WriteIndent "End of myscript"

Output:

    PS C:\scripting> .\Indent-Output.ps1
    Start of myscript
        Start of myfn
            Start of myFnNested
            End of myFnNested
        End of myfn 
    End of myscript
