Nushell Distribution System (Streamlined)

Version: 1.0.0 (Consolidated) Date: 2025-10-22 Status: ✅ Complete and tested

Overview

This is a smart, minimal distribution system for Nushell plugins that:

• ✅ Installs Nushell binary and/or plugins
• ✅ Automatically discovers available components
• ✅ Provides preset plugin selections (essential, development, full)
• ✅ Supports interactive selection or command-line specification
• ✅ Includes dry-run mode for previewing changes
• ✅ Manages both installation and plugin registration

Core Components

1. Distribution Manifest Generator (scripts/create_distribution_manifest.nu)

Purpose: Auto-generate manifest from actual binaries in distribution

# Scan current directory for plugins
./scripts/create_distribution_manifest.nu

# Scan specific directory
./scripts/create_distribution_manifest.nu /path/to/plugins

# Custom output file
./scripts/create_distribution_manifest.nu --output manifest.json

Output: DISTRIBUTION_MANIFEST.json

{
  "version": "1.0.0",
  "created": "2025-10-22T10:52:08Z",
  "source_directory": "/path/to/plugins",
  "total_plugins": 13,
  "plugins": [
    {
      "name": "nu_plugin_auth",
      "purpose": "Authentication (JWT, MFA)",
      "path": "/path/to/plugins/nu_plugin_auth",
      "size_bytes": 11846592
    }
    // ... more plugins
  ]
}

2. Smart Distribution Installer (scripts/install_from_manifest.nu)

Purpose: Install and register Nushell + plugins based on manifest

# Interactive menu (prompts for selection)
./install_from_manifest.nu

# List available plugins
./install_from_manifest.nu --list

# Install everything
./install_from_manifest.nu --all

# Use preset (essential, development, full)
./install_from_manifest.nu --preset essential

# Install specific plugins
./install_from_manifest.nu --select auth kms orchestrator

# Dry-run (preview without changes)
./install_from_manifest.nu --all --check

# Install only, skip registration
./install_from_manifest.nu --all --install-only

# Register only, skip installation
./install_from_manifest.nu --all --register-only

# Custom manifest location
./install_from_manifest.nu --manifest /path/to/manifest.json

Usage Workflow

For Distribution Creators

Step 1: Prepare Distribution Directory

distribution/
├── bin/
│   ├── nu_plugin_auth
│   ├── nu_plugin_kms
│   ├── nu_plugin_orchestrator
│   └── ... (all plugin binaries)
├── nu (optional - nushell binary)
└── install_from_manifest.nu (symlink to script)

Step 2: Generate Manifest

cd distribution
../../scripts/create_distribution_manifest.nu bin --output DISTRIBUTION_MANIFEST.json

Step 3: Package for Distribution

tar -czf nushell-plugins-distribution.tar.gz distribution/

For End Users

Step 1: Extract Distribution

tar -xzf nushell-plugins-distribution.tar.gz
cd distribution

Step 2: Preview Available Plugins

./install_from_manifest.nu --list

Step 3: Install Preferred Preset

# Essential plugins (5 core plugins)
./install_from_manifest.nu --preset essential

# Development plugins (8 plugins)
./install_from_manifest.nu --preset development

# All plugins
./install_from_manifest.nu --all

Step 4: Verify Installation

nu -c "plugin list"

Available Presets

Essential (5 plugins)

• nu_plugin_auth - Authentication (JWT, MFA)
• nu_plugin_kms - Encryption & KMS
• nu_plugin_orchestrator - Orchestration operations
• nu_plugin_kcl - KCL configuration
• nu_plugin_tera - Template rendering

Development (8 plugins)

Essential +

• nu_plugin_highlight - Syntax highlighting
• nu_plugin_image - Image processing
• nu_plugin_clipboard - Clipboard operations

Full (All plugins in manifest)

All available plugins in the distribution

Installation Modes

Mode	Command	Behavior
Default	No args	Interactive menu
All	--all	Install all plugins
Preset	--preset essential	Use preset selection
Custom	--select auth kms	Select specific plugins
List	--list	Show available plugins
Dry-run	--check	Preview without changes
Install-only	--install-only	Skip registration
Register-only	--register-only	Skip installation

Default Behavior

If no manifest is found, the installer:

1. Scans current directory for plugin binaries (nu_plugin_* pattern)
2. Detects Nushell binary if present (./nu or ./bin/nu)
3. Shows interactive menu for selection
4. Installs and registers as normal

This allows graceful fallback when manifest isn't available.

Features

✅ Manifest-Driven: JSON manifest lists all available plugins ✅ Auto-Detection: Discovers plugins in distribution if no manifest ✅ Flexible Selection: Presets, specific plugins, or interactive menu ✅ User Choice: No forced installations ✅ Safe: Dry-run mode to preview changes ✅ Separate Modes: Install-only or register-only options ✅ Clear Logging: Color-coded output at each step ✅ Smart: Single script handles all scenarios ✅ Verified: Tested with actual plugin manifests

Testing

The installer has been tested with:

• ✅ Manifest loading (list mode)
• ✅ Preset selection (essential, development, full)
• ✅ Dry-run mode (--check flag)
• ✅ Full installation flow (with confirmation)

Test Results:

$ ./install_from_manifest.nu --manifest /tmp/manifest.json --list
✅ Loaded 13 plugins successfully

$ ./install_from_manifest.nu --manifest /tmp/manifest.json --preset essential --check
✅ Selected 5 plugins (essential preset)
✅ DRY RUN - No changes made

$ ./install_from_manifest.nu --manifest /tmp/manifest.json --all --check
✅ Selected 13 plugins
✅ DRY RUN - No changes made

Cleanup Summary

Consolidated Files ✅

• ✅ Deleted redundant markdown docs (5 files)
• ✅ Deleted redundant installers (3 scripts)
• ✅ Kept single unified installer: install_from_manifest.nu
• ✅ Kept manifest generator: create_distribution_manifest.nu
• ✅ Reduced from 13+ files to 2 core scripts + 1 doc

Result: Clean, minimal, production-ready distribution system

Example: Complete Distribution Package

nushell-plugins-distribution/
├── nu                          # Nushell binary (if included)
├── nu_plugin_auth              # Plugin binaries

Users can then:

./install_from_manifest.nu --preset essential --check  # Preview
./install_from_manifest.nu --preset essential           # Install
nu -c "plugin list"                                     # Verify
