# src/Private/Traversal/Get-TreeChild.ps1 <# .SYNOPSIS Enumerates the children of a path. .DESCRIPTION Get-TreeChild uses the provided TreeChildProvider to fetch the files and directories directly under a path. It applies filtering (like HideHidden) and returns the visible items to the traversal engine. #> function Get-TreeChild { [CmdletBinding()] param( [Parameter(Mandatory)] [string] $Path, [string] $RootPath, [int] $Depth = 0, [Parameter(Mandatory)] [object] $Provider, [string[]] $Include, [string[]] $Exclude, [switch] $HideHidden, [switch] $HideSystem, [switch] $DirectoryOnly ) if (-not $PSBoundParameters.ContainsKey('Debug') -and $PSCmdlet) { $DebugPreference = $PSCmdlet.GetVariableValue('DebugPreference') } if (-not $PSBoundParameters.ContainsKey('Verbose') -and $PSCmdlet) { $VerbosePreference = $PSCmdlet.GetVariableValue('VerbosePreference') } if ([string]::IsNullOrWhiteSpace($RootPath)) { $RootPath = $Path } if ($null -eq $Provider.GetChildren) { $styleProfile = Get-ActiveShowTreeStyleProfile throw ($styleProfile.UIStrings.Errors.MissingGetChildren -f $Provider.Name) } $raw = & $Provider.GetChildren $Path $Depth if ($null -eq $raw) { return } foreach ($item in @($raw.Files)) { if (Test-TreeItemVisible ` -Item $item ` -Include $Include ` -Exclude $Exclude ` -RootPath $RootPath ` -HideHidden:$HideHidden ` -HideSystem:$HideSystem ` -DirectoryOnly:$DirectoryOnly) { $item } } foreach ($item in @($raw.Directories)) { if (Test-TreeItemVisible ` -Item $item ` -Include $Include ` -Exclude $Exclude ` -RootPath $RootPath ` -HideHidden:$HideHidden ` -HideSystem:$HideSystem ` -DirectoryOnly:$DirectoryOnly) { $item } } } |
