Examples

Example 1
This example demonstrates how to use this function to suppress all output from a script block so it doesn’t break the progress bar.

$result = Invoke-SpectreCommandWithProgress {
    param (
        $Context
    )
    $task1 = $Context.AddTask("Starting a process that generates noise")
    $task1.Increment(50)
    $value = Invoke-SpectreScriptBlockQuietly -Level Quiet -Command {
        Write-Output "Things..."
        Write-Output "And stuff..."
        Write-Error "This is an error"
        Start-Sleep -Seconds 3
        Write-Output "But it shouldn't break progress bar rendering"
    }
    $task1.Increment(50)
    return $value
}
Write-SpectreHost "Result: $result"
