function Get-ListPanel { <# .SYNOPSIS Create a list panel for displaying items in a TUI. .DESCRIPTION This function generates a list panel that displays items in a TUI (Text User Interface) using Spectre.Console. It formats the items based on whether they are selected or not, and handles special cases like parent directories. .PARAMETER List An array of strings to display in the list. Each item can be a file path, a test name, or a special item like '..' for parent directories. .PARAMETER SelectedItem The item that is currently selected in the list. This will be highlighted differently from unselected items. .EXAMPLE Get-ListPanel -List @('file1.txt', 'file2.txt', '..') -SelectedItem 'file1.txt' This example creates a list panel with three items, highlighting 'file1.txt' as the selected item. .NOTES This is meant to be called by the main TUI function: Show-PesterResult #> [CmdletBinding()] param ( [array] $List, [string] $SelectedItem, [string]$SelectedPane = "list" ) $paneColor = if($SelectedPane -ne "list") { # If the selected pane is not preview, return an empty panel "blue" } else { "white" } $unselectedStyle = @{ RootColor = [Spectre.Console.Color]::Grey SeparatorColor = [Spectre.Console.Color]::Grey StemColor = [Spectre.Console.Color]::Grey LeafColor = [Spectre.Console.Color]::White } $results = $List | ForEach-Object { $name = $_ if($name -eq '..') { # This is a parent item, so we show it as a folder if ($name -eq $SelectedItem) { Write-SpectreHost ":up_arrow: [Turquoise2]$name[/]" -PassThru | Format-SpectrePadded -Padding 1 } else { Write-SpectreHost "$name" -PassThru | Format-SpectrePadded -Padding 0 } } elseif(Test-Path $name){ $relativePath = [System.IO.Path]::GetRelativePath( (Get-Location).Path, $name ) if ($name -eq $SelectedItem) { Format-SpectreTextPath -Path $relativePath | Format-SpectrePadded -Padding 1 } else { $formatSpectreTextPathSplat = @{ Path = $relativePath PathStyle = $unselectedStyle } Format-SpectreTextPath @formatSpectreTextPathSplat | Format-SpectrePadded -Padding 0 } } else { if ($name -eq $SelectedItem) { $writeSpectreHostSplat = @{ PassThru = $true Message = ":right_arrow: [Turquoise2]$name[/]" } Write-SpectreHost @writeSpectreHostSplat | Format-SpectrePadded -Padding 1 } else { Write-SpectreHost $name -PassThru | Format-SpectrePadded -Padding 0 } } } $results | Format-SpectreRows | Format-SpectrePanel -Header "[white]List[/]" -Expand -Color $paneColor } |
