ColorScripts-Enhanced PowerShell Module

Credits: This project owes its existence to the foundational work of two developers. The beautiful ANSI art scripts were originally created and/or sourced by Derek Taylor (DistroTube) in his project shell-color-scripts. The collection was then ported to PowerShell by Scott McKendry as ps-color-scripts. ColorScripts-Enhanced builds upon their efforts by introducing a high-performance caching system, PowerShell Cross-Platform support on Linux and Mac, an expanded command set, and a formal module structure.

A high-performance PowerShell module for displaying beautiful ANSI colorscripts in your terminal with intelligent caching for 6-19x faster load times.

+ 495 more colorscripts available!

Quick Start (Less Than a Minute)

Install-Module -Name ColorScripts-Enhanced -Scope CurrentUser
Import-Module ColorScripts-Enhanced
Add-ColorScriptProfile              # Optional: add to profile immediately
Show-ColorScript

Requires PowerShell 5.1 or later. PowerShell 7.4+ recommended for best performance and PSResourceGet support.

PowerShell Support

We test every change across Windows, macOS, and Linux. See the full matrix in docs/POWERSHELL-VERSIONS.md.

Platform	PowerShell 5.1	PowerShell 7.x
Windows	✅ Unit tests, module validation	✅ Unit tests, ScriptAnalyzer, help validation
macOS	❌ Not available	✅ Unit tests, ScriptAnalyzer
Linux	❌ Not available	✅ Unit tests, ScriptAnalyzer

We intentionally run ScriptAnalyzer only on PowerShell 7.x because the 5.1 engine applies different rules that conflict with modern cross-platform patterns.

Install a Nerd Font for Custom Glyphs

Several scripts display Nerd Font icons (powerline separators, dev icons, logos). Without a Nerd Font, those glyphs render as blank boxes. Pick one of the patched fonts from nerdfonts.com and set it as your terminal font:

Download a font (e.g., Cascadia Code, FiraCode, JetBrainsMono) from the Nerd Fonts releases.
Install on Windows: extract the .zip, select the .ttf files, right-click → Install for all users. macOS: brew install --cask font-caskaydia-cove-nerd-font (or double-click in Font Book). Linux: copy the .ttf files to ~/.local/share/fonts (or /usr/local/share/fonts), then run fc-cache -fv.
Update your terminal (Windows Terminal, VS Code, Alacritty, etc.) to use the installed Nerd Font for each profile.
Verify by running:

Show-ColorScript -Name nerd-font-test

The script will render checkmarks and dev icons when the font is configured correctly.

Installation

Option 1: PowerShell Gallery (Recommended)

The module is published to the PowerShell Gallery, making installation a single command:

# PowerShellGet (Windows PowerShell 5.1 / PowerShell 7)
Install-Module -Name ColorScripts-Enhanced -Scope CurrentUser

# PSResourceGet (PowerShell 7.4+)
Install-PSResource -Name ColorScripts-Enhanced -Scope CurrentUser

# Update to latest release later
Update-Module ColorScripts-Enhanced

💡 Tip: Set Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass if your environment restricts script execution during installation.

Option 2: GitHub Packages (Optional)

If you prefer GitHub Packages (for private mirrors or enterprise environments):

$owner  = 'Nick2bad4u'
$source = "https://nuget.pkg.github.com/$owner/index.json"

Register-PSRepository -Name ColorScriptsEnhanced-GitHub -SourceLocation $source -PublishLocation $source -InstallationPolicy Trusted -PackageManagementProvider NuGet
Install-Module -Name ColorScripts-Enhanced -Repository ColorScriptsEnhanced-GitHub -Scope CurrentUser

Authenticate with a GitHub PAT (Package Read scope) if prompted.

Option 3: Manual Installation

Copy the ColorScripts-Enhanced folder to one of your PowerShell module paths:

# See available module paths
$env:PSModulePath -split ';'

# Recommended location (user-specific)
$modulePath = "$env:USERPROFILE\Documents\PowerShell\Modules\ColorScripts-Enhanced"

# Copy the module folder to the destination
Copy-Item -Path ".\ColorScripts-Enhanced" -Destination $modulePath -Recurse -Force

Import the module:

Import-Module ColorScripts-Enhanced

(Optional) Add to your PowerShell profile for automatic loading:

Add-Content -Path $PROFILE.CurrentUserAllHosts -Value "Import-Module ColorScripts-Enhanced"

Alternatively, run Add-ColorScriptProfile -Scope CurrentUserAllHosts -SkipStartupScript after importing the module.

Option 4: Quick Test (Without Installation)

Import-Module ".\ColorScripts-Enhanced\ColorScripts-Enhanced.psd1"

(Optional) Add to Your PowerShell Profile

Use the built-in helper to import the module (and optionally display a random colorscript) at shell startup:

Add-ColorScriptProfile

Key options:

Add-ColorScriptProfile -SkipStartupScript – import the module without showing a script on launch.
Add-ColorScriptProfile -Scope CurrentUserCurrentHost – limit to the current host (e.g., just VS Code).
Add-ColorScriptProfile -Path .\MyCustomProfile.ps1 – target an explicit profile file.

Usage

Display a Random Colorscript

Show-ColorScript
# or use the alias
scs

Display a Specific Colorscript

Show-ColorScript -Name "mandelbrot-zoom"
# or
scs mandelbrot-zoom

# Use wildcards to target a family of scripts
Show-ColorScript -Name "aurora-*"

List All Available Colorscripts

Show-ColorScript -List
# or
Get-ColorScriptList

# Return objects for automation
$scripts = Get-ColorScriptList -AsObject
$scripts | Select-Object Name, Category, Tags | Format-Table

# Show additional metadata in the table view
Get-ColorScriptList -Detailed

Filter by Category or Tag

# All pattern-based scripts
Get-ColorScriptList -Category Patterns

# Recommended scripts surfaced by metadata
Get-ColorScriptList -Tag Recommended -Detailed

# Display a random recommended script and return its metadata
Show-ColorScript -Tag Recommended -PassThru

Build Cache for Faster Performance

# Cache all colorscripts (recommended)
Build-ColorScriptCache

# Cache specific colorscripts
Build-ColorScriptCache -Name "bars","hearts","arch"

# Force rebuild cache
Build-ColorScriptCache -Force

# Cache every script whose name starts with "aurora-"
Build-ColorScriptCache -Name "aurora-*"

Build-ColorScriptCache caches the entire library by default, so specifying -All is optional. Use -PassThru when you need per-script status objects. Without it you’ll just see the concise on-screen summary.

Clear Cache

# Clear all cache files
Clear-ColorScriptCache -All

# Clear specific cache
Clear-ColorScriptCache -Name "mandelbrot-zoom"

# Preview what would be deleted (no files removed)
Clear-ColorScriptCache -Name "mandelbrot-zoom" -DryRun

# Clear caches in an alternate location
Clear-ColorScriptCache -Name "mandelbrot-zoom" -Path 'C:/temp/colorscripts-cache'

# Remove all caches that match a wildcard pattern
Clear-ColorScriptCache -Name "aurora-*" -Confirm:$false

Tip: Set COLOR_SCRIPTS_ENHANCED_CACHE_PATH to redirect cache files to a custom directory for CI or ephemeral test runs.

Persist Defaults with Configuration

# Inspect current configuration (cache path, startup behaviour)
Get-ColorScriptConfiguration

# Persist a custom cache path and disable automatic profile startup
Set-ColorScriptConfiguration -CachePath 'D:/Temp/ColorScriptsCache' -ProfileAutoShow:$false

# Reset everything to defaults
Reset-ColorScriptConfiguration

Configuration is stored in %APPDATA%/ColorScripts-Enhanced/config.json (or the equivalent on macOS/Linux). Set COLOR_SCRIPTS_ENHANCED_CONFIG_ROOT to redirect the configuration location for portable or CI scenarios.

Export Metadata for External Tools

# Emit metadata objects to the pipeline
$metadata = Export-ColorScriptMetadata -IncludeFileInfo -IncludeCacheInfo

# Persist a JSON snapshot for front-end tooling
Export-ColorScriptMetadata -Path ./dist/colorscripts-metadata.json -IncludeFileInfo

Metadata includes categories, tags, descriptions, script paths, and optional cache details–perfect for building dashboards, search interfaces, or gallery listings.

Scaffold a New Colorscript

# Create a new colorscript skeleton in the Scripts directory
$scaffold = New-ColorScript -Name 'my-awesome-script' -GenerateMetadataSnippet -Category 'Artistic' -Tag 'Custom','Demo'

# Inspect metadata guidance for ScriptMetadata.psd1 updates
$scaffold.MetadataGuidance

The scaffolded script includes a UTF-8 template with placeholders so you can paste ANSI art directly. The optional metadata guidance hints at how to categorise the new script in ScriptMetadata.psd1.

Bypass Cache (Force Fresh Execution)

Show-ColorScript -Name "bars" -NoCache

Test the Entire Collection

# Sequential run with metadata-rich summary results
.\ColorScripts-Enhanced\Test-AllColorScripts.ps1 -Filter 'bars' -Delay 0 -SkipErrors

# Parallel run (PowerShell 7+) for faster CI coverage
.\ColorScripts-Enhanced\Test-AllColorScripts.ps1 -Parallel -SkipErrors -ThrottleLimit 4

Performance

Before Caching

Simple scripts: 30-50ms
Complex scripts: 200-400ms

After Caching

All scripts: 5-20ms
Improvement: 6-19x faster!

Example Performance Gains

Script	Without Cache	With Cache	Speedup
bars	31ms	5ms	6x
gradient-bars	65ms	8ms	8x
mandelbrot-zoom	365ms	19ms	19x

Cache System

How It Works

First Run: Script executes normally and output is cached
Subsequent Runs: Cached output is displayed instantly
Auto-Invalidation: Cache updates when source script changes
OS-Wide: Single cache location works from any directory

Cache Location

The module stores cached output in platform-specific directories:

Windows:

C:\Users\[Username]\AppData\Roaming\ColorScripts-Enhanced\cache\

macOS:

~/Library/Application Support/ColorScripts-Enhanced/cache/

Linux:

~/.cache/ColorScripts-Enhanced/

To find your cache location programmatically:

# Windows
$env:APPDATA\ColorScripts-Enhanced\cache

# macOS
~/Library/Application Support/ColorScripts-Enhanced/cache

# Linux
~/.cache/ColorScripts-Enhanced

Cache Files

One .cache file per colorscript
Contains pre-rendered ANSI output
Average size: ~20KB per file
Total size: ~4.9MB for 498+ scripts

Examples

Add to PowerShell Profile

Display a random colorscript every time you open PowerShell:

# Edit your profile
notepad $PROFILE.CurrentUserAllHosts

# Add this line:
Import-Module ColorScripts-Enhanced
Show-ColorScript

Create Custom Alias

# Add to profile
Set-Alias -Name cs -Value Show-ColorScript

Build Cache on Module Import

# Add to profile after Import-Module
Import-Module ColorScripts-Enhanced
Build-ColorScriptCache

Available Colorscripts

The module includes 498+ colorscripts including:

Fractals: mandelbrot-zoom, julia-morphing, barnsley-fern, koch-snowflake
Patterns: kaleidoscope, wave-pattern, rainbow-waves, gradient-bars
Characters: pacman, space-invaders, tux, darthvader
Nature: galaxy-spiral, aurora-storm, crystal-grid, nebula
Mathematical: fibonacci-spiral, penrose-quasicrystal, hilbert-spectrum
And many more!

Use Show-ColorScript -List to see all available scripts.

Troubleshooting

Cache Not Working

# Rebuild cache
Build-ColorScriptCache -Force

# Check cache location
explorer "$env:APPDATA\ColorScripts-Enhanced\cache"

Cache Files Locked or Refusing to Delete

# Preview what would be removed without touching the filesystem
Clear-ColorScriptCache -Name 'bars' -DryRun

# Force deletion after closing terminals that might hold locks
Clear-ColorScriptCache -Name 'bars' -Confirm:$false

If a cache file stays locked, close any terminals showing the script, then retry the commands above. As a last resort, specify -Path with a custom cache root and move the cache elsewhere.

Module Not Found

# Verify module path
Get-Module ColorScripts-Enhanced -ListAvailable

# Check PSModulePath
$env:PSModulePath -split ';'

Colorscript Not Displaying

# Try without cache
Show-ColorScript -Name "scriptname" -NoCache

# Check if script exists
Get-ColorScriptList

Icons or glyphs show as squares

# Confirm Nerd Font installation
Show-ColorScript -Name nerd-font-test

# If icons are missing:
# 1\. Install a Nerd Font from https://www.nerdfonts.com/
# 2\. Set your terminal profile to use the installed font
# 3\. Restart the terminal session
