# Module: Orbit.Tools # Function: Helper # Author: David Eberhardt # Updated: 29-OCT-2021 # Status: Live function Get-WriteBetterProgressSteps { <# .SYNOPSIS Max number of Steps Write-BetterProgress is used to calculate PercentComplete .DESCRIPTION Determines the number of times 'Write-BetterProgress' is called in the provided Code .PARAMETER Code Required. Code to read. Planned: If not provided, will use the code of the calling function .PARAMETER MaxId Optional. Number of cascaded levels to use. If not provided, will assume single level (ID 0) .EXAMPLE Get-WriteBetterProgressSteps -Code $Code -MaxId 1 Runs through the provided Code object (or, if not provided, the code of the calling function) Returns integer value for each level discovered .INPUTS System.String, System.Integer .OUTPUTS System.Object .NOTES Helper function to create a dynamic count how often Write-BetterProgress is used in a command with a given ID. Used by the Function itself to determine how many steps there are to be calculated against. .COMPONENT SupportingFunction .FUNCTIONALITY Uses Write-Progress without its inherent clunkyness, improving on consistency .LINK https://github.com/DEberhardt/Orbit/tree/main/docs/Orbit.Tools/Get-WriteBetterProgressSteps.md .LINK https://github.com/DEberhardt/Orbit/tree/main/docs/Orbit.Tools/Write-BetterProgress.md .LINK https://github.com/DEberhardt/Orbit/tree/main/docs/about/about_Supporting_Functions.md .LINK https://github.com/DEberhardt/Orbit/tree/main/docs/ .LINK Get-WriteBetterProgressSteps #> [CmdletBinding()] [OutputType([System.Int32])] param( [Parameter(Mandatory)] $Code, [Parameter()] [int]$MaxId = 0 ) #param begin { #Show-OrbitFunctionStatus -Level Live #Write-Verbose -Message "[BEGIN ] $($MyInvocation.MyCommand)" # Setting Preference Variables according to Upstream settings if (-not $PSBoundParameters['Verbose']) { $VerbosePreference = $PSCmdlet.SessionState.PSVariable.GetValue('VerbosePreference') } if (-not $PSBoundParameters['Confirm']) { $ConfirmPreference = $PSCmdlet.SessionState.PSVariable.GetValue('ConfirmPreference') } if (-not $PSBoundParameters['WhatIf']) { $WhatIfPreference = $PSCmdlet.SessionState.PSVariable.GetValue('WhatIfPreference') } if (-not $PSBoundParameters['Debug']) { $DebugPreference = $PSCmdlet.SessionState.PSVariable.GetValue('DebugPreference') } else { $DebugPreference = 'Continue' } if ( $PSBoundParameters['InformationAction']) { $InformationPreference = $PSCmdlet.SessionState.PSVariable.GetValue('InformationAction') } else { $InformationPreference = 'Continue' } #Initialising Counters $ScriptAst = [System.Management.Automation.Language.Parser]::ParseInput($Code, [ref] $null, [ref]$null) #Retrieving Call Stack $Stack = Get-PSCallStack $FunctionCalling = $Stack[1].FunctionName #$FunctionCalling = $MyInvocation.InvocationName } #begin process { #Write-Verbose -Message "[PROCESS] $($MyInvocation.MyCommand)" 0..$MaxId | ForEach-Object { Write-Verbose -Message "[PROCESS] $($MyInvocation.MyCommand) - Processing available Steps for ID:$_" $Steps = ($ScriptAst.Extent.Text -Split "Write-BetterProgress -Id $_ " | Measure-Object | Select-Object -ExpandProperty Count) - 2 # Deducting two to be precise if ($PSBoundParameters['Debug']) { "Function: '$FunctionCalling': Steps for Level $_`: $Steps" | Write-Debug } Write-Output $Steps } } #process end { #Write-Verbose -Message "[END ] $($MyInvocation.MyCommand)" } #end } # Get-WriteBetterProgressSteps |
