Allow redirection of progress into stdout/file

[LinqLover]

In certain situations, for example in CI environments such as GitHub Actions or others, there is no host window that can display the progress bars generated by Write-Progress[Ex]. It would be nice if this mode could be activated or even auto-detected and all progress could then be redirected to stdout.

Good point...

WriteProgressEx uses a pipe (and stdout) now.
See /Examples/Write-ProgressEx.pipe.ps1

You can also override the scriptblocks that show the messages
see /Examples/Write-ProgressEx.counter.ps1

Write-ProgressEx params:

    # Message templates
    [scriptblock[]]$MessageOnFirstIteration,
    [scriptblock[]]$MessageOnNewActivity,
    [scriptblock[]]$MessageOnNewStatus,
    [scriptblock[]]$MessageOnCompleted,

    # The cmdlet output no messages
    [switch]$ShowMessages,
    [switch]$ShowMessagesOnFirstIteration = $ShowMessages -or $MessageOnFirstIteration,
    [switch]$ShowMessagesOnNewActivity = $ShowMessages -or $MessageOnNewActivity,
    [switch]$ShowMessagesOnNewStatus = $ShowMessages -or $MessageOnNewStatus,
    [switch]$ShowMessagesOnCompleted = $ShowMessages -or $MessageOnCompleted

PowerShell provides the Verbose Stream and Information Stream.
I need to think this streams.
Thanks
