################################################################################ <# .SYNOPSIS Sets up custom command not found handling with AI assistance. .DESCRIPTION Configures PowerShell to handle unknown commands by either navigating to directories or using AI to interpret user intent. The handler first tries any existing command not found handler, then checks if the command is a valid path for navigation, and finally offers AI assistance for unknown commands. .EXAMPLE Set-GenXdevAICommandNotFoundActions #> function Set-GenXdevAICommandNotFoundActions { [CmdletBinding()] param() begin { # initialize logging for function start Write-Verbose "Starting Set-GenXdevAICommandNotFoundActions" # store reference to existing handler if it's not already our handler $script:originalHandler = $null $currentHandler = $ExecutionContext.InvokeCommand.CommandNotFoundAction # check if handler is already installed by looking for unique string if ($null -ne $currentHandler) { $handlerString = $currentHandler.ToString() if ($handlerString.Contains("Do you want AI to figure out")) { Write-Verbose "AI Command handler already installed - exiting" return } $script:originalHandler = $currentHandler Write-Verbose "Stored original command handler for chaining" } } process { try { # initialize global variable to track last command $global:lastCmd = "" Write-Verbose "Configuring new CommandNotFoundAction handler" # define the command not found action handler $ExecutionContext.InvokeCommand.CommandNotFoundAction = { param($CommandName, $CommandLookupEventArgs) # try original handler first if one exists if ($null -ne $script:originalHandler) { Write-Verbose "Executing original handler" & $script:originalHandler $CommandName $CommandLookupEventArgs # exit if original handler handled the command if ($CommandLookupEventArgs.StopSearch) { return } } # check if command is a directory path and handle navigation if (Test-Path -Path $CommandName -PathType Container) { $CommandLookupEventArgs.CommandScriptBlock = { Set-Location $CommandName Get-ChildItem }.GetNewClosure() $CommandLookupEventArgs.StopSearch = $true return } # skip internal commands and get- commands if ($CommandLookupEventArgs.CommandOrigin -eq "Internal" -or $CommandName -like "get-*") { return } # configure AI assistance for unknown commands $CommandLookupEventArgs.CommandScriptBlock = { $userChoice = $host.ui.PromptForChoice( "Command not found", "Do you want AI to figure out what you want?", @("&Nah", "&Yes"), 0) if ($userChoice -eq 0) { return } Write-Host -ForegroundColor Yellow "What did you want to do?"
