################################################################################ <# .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-GenXdevAICommandNotFoundAction #> function Set-GenXdevAICommandNotFoundAction { [CmdletBinding(SupportsShouldProcess)] param() begin { Microsoft.PowerShell.Utility\Write-Verbose "Starting Set-GenXdevAICommandNotFoundAction" # store reference to existing handler if it's not already our handler $script:originalHandler = $null $currentHandler = $ExecutionContext.InvokeCommand.CommandNotFoundAction # check if handler is already installed if ($null -ne $currentHandler) { $handlerString = $currentHandler.ToString() if ($handlerString.Contains("Do you want AI to figure out")) { Microsoft.PowerShell.Utility\Write-Verbose "AI Command handler already installed - exiting" return } $script:originalHandler = $currentHandler Microsoft.PowerShell.Utility\Write-Verbose "Stored original command handler for chaining" } } process { if (-not $PSCmdlet.ShouldProcess("Command not found handling", "Set AI assistance handler")) { return } try { # Add flag to prevent recursion $script:insideCommandHandler = $false Microsoft.PowerShell.Utility\Write-Verbose "Configuring new CommandNotFoundAction handler" # define the command not found action handler $ExecutionContext.InvokeCommand.CommandNotFoundAction = { param($CommandName, $CommandLookupEventArgs) # prevent recursion if ($script:insideCommandHandler) { Microsoft.PowerShell.Utility\Write-Debug "Preventing recursive call for command: $CommandName" return } $script:insideCommandHandler = $true $origPSDebugPreference = $PSDebugPreference $origErrorActionPreference = $ErrorActionPreference $origVerbosePreference = $VerbosePreference $origWarningPreference = $WarningPreference try { # suppress unnecessary output during handler execution $PSDebugPreference = "continue" $ErrorActionPreference = 'SilentlyContinue' $VerbosePreference = "SilentlyContinue" $WarningPreference = "SilentlyContinue" # skip .NET method calls if ($CommandName -match '^\[.*\]::') { return } # try original handler first if ($null -ne $script:originalHandler) { try { & $script:originalHandler $CommandName $CommandLookupEventArgs if ($CommandLookupEventArgs.StopSearch) { return } } catch { Microsoft.PowerShell.Utility\Write-Debug "Original handler failed: $_" } } } finally { # restore original preferences $PSDebugPreference = $origPSDebugPreference $ErrorActionPreference = $origErrorActionPreference $VerbosePreference = $origVerbosePreference $WarningPreference = $origWarningPreference $script:insideCommandHandler = $false } # handle directory navigation if (Microsoft.PowerShell.Management\Test-Path -Path $CommandName -PathType Container) { $CommandLookupEventArgs.CommandScriptBlock = { Microsoft.PowerShell.Management\Set-Location $CommandName Microsoft.PowerShell.Management\Get-ChildItem }.GetNewClosure() $CommandLookupEventArgs.StopSearch = $true return } # skip internal and get- commands if ($CommandLookupEventArgs.CommandOrigin -eq "Internal" -or $CommandName -like "get-*") { return } # configure AI assistance $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 } GenXdev.Windows\Send-Key ($MyInvocation.line) -Escape Microsoft.PowerShell.Utility\Write-Host -ForegroundColor Yellow "What did you want to do?"
