Write-ProgressEx – extended write-progress cmdlet

Write-ProgressEx extends the functionality of the standard powershell cmdlet. Write-ProgressEx is a powershell advanced function that provides a simple way to show ProgressBars with PercentComplete and SecondsRemaining.

The cmdlet:

• works with pipe;
• works with empty activity string;
• completes all inner progresses if no parameters;
• automatically completes with pipe;
• automatically calculates percents, remaining seconds and elapsed time;
• automatically displays current iteration and totals on progress bar;
• automatically displays info with a progress bar and at the console title;
• automatically set parent id for a inner loop;
• stores totals, current values and actual parameters into the module hashtable;
• provides get/set cmdlets to access actual parameters;
• uses script blocks to show messages with date, time, iterations and elapsed time on events:
  • first iteration;
  • activity changed;
  • status changed;
  • completed.
• provides a counter functional. See Write-ProgressEx as a counter;
• uses the caller function name or the caller script file name as the Activity;
• accepts -ShowProgressBar Auto parameter to reduce the overhead for redrawing a screen. It recognizes None and Force values also.

Note: the function is not safe with multi-thread.

Examples

A pipe and a simple loop:

$range1 = 1..20
$range1 | Write-ProgressEx "loop 1" -Total $range1.Count -ShowMessages | ForEach-Object {
    # ....
}

$range2 = 1..15
$range2 | ForEach-Object {
    # ....
    Write-ProgressEx "loop 2" -Total $range2.Count -Increment
}

Write-ProgressEx #close all progress bars

Pipes in nested loops:

$outer = 1..20
$inner = 1..50

$outer | Write-ProgressEx "pipe nodes" -Status "outer" -Total $outer.Count -ShowMessages | ForEach-Object {
    $inner | Write-ProgressEx "pipe names" -id 1 -Status "inner" -Total $inner.Count | ForEach-Object {
        # ....
    }
}

A long time command:

$path = $env:homepath
$files = Get-ChildItem $path -Recurse | Write-ProgressEx $path

More samples are in the folder Examples.
