############################################################################### <# .SYNOPSIS Gets the configured directory for face image files used in GenXdev.AI operations. .DESCRIPTION This function retrieves the global face directory used by the GenXdev.AI module for various face recognition and AI operations. It checks Global variables first (unless SkipSession is specified), then falls back to persistent preferences, and finally uses system defaults. .PARAMETER FacesDirectory Optional faces directory override. If specified, this directory will be returned instead of retrieving from configuration. .PARAMETER SessionOnly Use alternative settings stored in session for AI preferences like Language, Image collections, etc .PARAMETER ClearSession Clear the session setting (Global variable) before retrieving .PARAMETER PreferencesDatabasePath Database path for preference data files .PARAMETER SkipSession Dont use alternative settings stored in session for AI preferences like Language, Image collections, etc .EXAMPLE Get-AIKnownFacesRootpath Gets the currently configured faces directory from Global variables or preferences. .EXAMPLE Get-AIKnownFacesRootpath -SkipSession Gets the configured faces directory only from persistent preferences, ignoring any session setting. .EXAMPLE Get-AIKnownFacesRootpath -ClearSession Clears the session faces directory setting and then gets the directory from persistent preferences. .EXAMPLE Get-AIKnownFacesRootpath "C:\MyFaces" Returns the specified directory after expanding the path. #> ############################################################################### function Get-AIKnownFacesRootpath { [CmdletBinding()] [Diagnostics.CodeAnalysis.SuppressMessageAttribute('PSAvoidGlobalVars', '')] param( ############################################################################### [Parameter( Mandatory = $false, Position = 0, HelpMessage = "Directory path for face image files" )] [string] $FacesDirectory, ############################################################################### [Parameter( Mandatory = $false, HelpMessage = ("Use alternative settings stored in session for AI " + "preferences like Language, Image collections, etc") )] [switch] $SessionOnly, ############################################################################### [Parameter( Mandatory = $false, HelpMessage = ("Clear the session setting (Global variable) before " + "retrieving") )] [switch] $ClearSession, ############################################################################### [Parameter( Mandatory = $false, HelpMessage = "Database path for preference data files" )] [string] $PreferencesDatabasePath, ############################################################################### [Parameter( Mandatory = $false, HelpMessage = ("Dont use alternative settings stored in session for " + "AI preferences like Language, Image collections, etc") )] [Alias("FromPreferences")] [switch] $SkipSession ) begin { #
