function Show-ColorScript { <# .SYNOPSIS Displays a colorscript with automatic caching. .LINK https://nick2bad4u.github.io/PS-Color-Scripts-Enhanced/docs/help-redirect.html?cmdlet=Show-ColorScript .DESCRIPTION Shows a beautiful ANSI colorscript in your terminal. If no name is specified, displays a random script. Uses intelligent caching for 6-19x faster performance. Name values accept wildcards; when multiple scripts match the provided pattern, the first alphabetical match is displayed and can be inspected with -PassThru. Use -All to cycle through all colorscripts in alphabetical order. Combine with -WaitForInput to pause between each script (press spacebar to continue). .PARAMETER Name The name of the colorscript to display (without .ps1 extension). Supports wildcards for partial matches. .PARAMETER List Lists all available colorscripts. .PARAMETER Random Display a random colorscript (default behavior). .PARAMETER All Cycle through all available colorscripts in alphabetical order. .PARAMETER WaitForInput When used with -All, pause after each colorscript and wait for spacebar to continue. Press 'q' to quit early. .PARAMETER NoCache Bypass cache and execute script directly. .PARAMETER NoClear When cycling through scripts with -All, skip clearing the host between displays so prior output remains visible. .PARAMETER Category Filter the available script set by one or more categories before selection occurs. .PARAMETER Tag Filter the available script set by tag metadata (case-insensitive). .PARAMETER PassThru Return the selected script metadata in addition to rendering output. .PARAMETER ReturnText Emit the rendered colorscript as pipeline output instead of writing directly to the console. .PARAMETER Quiet Suppress informational messaging emitted to the information stream while still rendering script output. .PARAMETER NoAnsiOutput Disable ANSI color codes in informational messages and rendered script text for plain-text environments. .PARAMETER ValidateCache Forces cache validation before rendering. Use when you need to rebuild cached colorscript output manually. .EXAMPLE Show-ColorScript Displays a random colorscript. .EXAMPLE Show-ColorScript -Name "mandelbrot-zoom" Displays the mandelbrot-zoom colorscript. .EXAMPLE Show-ColorScript -Name "aurora-*" Displays the first colorscript (alphabetically) whose name matches the wildcard. .EXAMPLE Show-ColorScript -List Lists all available colorscripts. .EXAMPLE scs hearts Uses the alias to display the hearts colorscript. .EXAMPLE Show-ColorScript -All Displays all colorscripts in alphabetical order continuously. .EXAMPLE Show-ColorScript -All -WaitForInput Displays all colorscripts one at a time, waiting for spacebar press between each. .EXAMPLE Show-ColorScript -All -Category Nature -WaitForInput Cycles through all nature-themed colorscripts with manual progression. #> [OutputType([pscustomobject], ParameterSetName = 'List')] [OutputType([pscustomobject], ParameterSetName = 'Named')]
