.SYNOPSIS Registers a callback function that is called before the Prompt function. .DESCRIPTION Registers a callback function that is called before the Prompt function. The callback runs on the main thread so it can be used to get the current directly for example. If you define your Prompt function, this function needs to be called after those definitions because the callback is achieved by overwriting the Prompt function. .PARAMETER ScriptBlock ScriptBlock that is called before the Prompt function. .PARAMETER ArgumentList The arguments passed to the ScriptBlock. .INPUTS None. .OUTPUTS PSCustomObject that represents a Job object. .EXAMPLE $job = Start-DTJobPromptCallback -ScriptBlock {Get-Location} $currentDirectory = Get-DTJobLatestOutput $job #> function Start-DTJobPromptCallback { [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSUseShouldProcessForStateChangingFunctions', '')] [OutputType([PSCustomObject])] param ( [Parameter(Mandatory=$true, ValueFromPipelineByPropertyName=$true)] [ScriptBlock]$ScriptBlock, [Parameter(ValueFromPipelineByPropertyName=$true)] [Object[]]$ArgumentList ) process { $sync = [System.Collections.Hashtable]::Synchronized(@{}) $arguments = @{ sync = $sync scriptBlock = $ScriptBlock argumentList = $ArgumentList } $callback = { $args.sync.output = $args.scriptBlock.Invoke($args.argumentList) } $script:globalStore.ReplacePrompt() $script:globalStore.AddPromptCallback($callback, $arguments) $job = [PSCustomObject]@{ Sync = $sync } $job } } |
