The hashtable should have a 'Value' key and a 'Children' key. The 'Value' key should contain the Spectre Console renderable item (text or other objects like calendars etc.) for the node of the tree, and the 'Children' key should contain an array of hashtables representing the child nodes of the node. See https://spectreconsole.net/widgets/tree for more information. .PARAMETER Data The hashtable to format as a tree. .PARAMETER Guide The type of line to use for the tree. .PARAMETER Color The color to use for the tree. This can be a Spectre Console color name or a hex color code. Default is the accent color defined in the script. .EXAMPLE $calendar = Write-SpectreCalendar -Date 2024-07-01 -PassThru $data = @{ Value = "Root" Children = @( @{ Value = "Child 1" Children = @( @{ Value = "Grandchild 1" Children = @() }, @{ Value = $calendar Children = @() } ) }, @{ Value = "Child 2" Children = @() } ) } Format-SpectreTree -Data $data -Guide BoldLine -Color "Green" #> [Reflection.AssemblyMetadata("title", "Format-SpectreTree")] param ( [Parameter(ValueFromPipeline, Mandatory)] [TreeItemTransformationAttribute()] [hashtable] $Data, [ValidateSet([SpectreConsoleTreeGuide], ErrorMessage = "Value '{0}' is invalid.
