Bun-Inspired Features - Implementation Complete! 🎉

This document summarizes all the Bun-inspired features that have been implemented in Home's package manager.

✅ Completed Features

1. Package Scripts (Like Bun/npm)

Status: ✅COMPLETE

Home now supports package scripts just like Bun! Define scripts in your ion.toml:

[scripts]
dev = "ion run src/main.home --watch"
build = "ion build src/main.home -o dist/app"
test = "ion test tests/"
bench = "ion bench bench/"
format = "ion fmt src/"
custom = "echo 'Your custom command here'"

Usage:

# List all scripts
ion pkg scripts

# Run a script
ion pkg run dev
ion pkg run build
ion pkg run test

Files Created:

• src/pkg/scripts.zig - Script runner with lifecycle hooks
• Updated ion pkg init to include default scripts

Features:

• Execute any shell command
• Lifecycle hooks (preinstall, postinstall, etc.)
• Beautiful colored output
• Error handling with exit codes
• Script listing command

2. Beautiful Progress UI

Status: ✅COMPLETE

Bun-style progress bars with speed indicators and spinners!

Features:

• Animated spinners during downloads
• Real-time speed tracking (MB/s)
• Progress bars with percentage
• Multi-package tracking
• Installation summary with stats

Example Output:

📦 Installing 24 packages...

⠋ http-router@1.0.0          [████████████████████] 100% | 2.3 MB/s
⠋ zyte@main                  [█████████░░░░░░░░░░░]  45% | 1.8 MB/s
✓ json-parser@2.1.0          [████████████████████] 100% | Done

⠋ 3/24 packages | 4.5s elapsed | avg 2.1 MB/s

✨ Installation complete!

📦 24 packages installed
⏱️  4.5s (avg 341 KB/s)
💾 12.4 MB disk space used
🔗 3 packages from cache (instant)
📥 21 packages downloaded

Files Created:

• src/pkg/progress.zig - Complete progress UI system
  • ProgressBar - Individual package progress
  • ProgressTracker - Multi-package coordination
  • InstallSummary - Post-installation stats

3. Dependency Tree Visualization

Status: ✅COMPLETE

Show dependency trees like bun pm ls:

ion pkg tree

Example Output:

📦 Dependency Tree:

my-app@1.0.0
├── http-router@1.0.0
│   ├── url-parser@2.1.0
│   └── header-utils@1.0.0
├── zyte@main
│   ├── webview@3.0.0
│   └── ipc@1.2.0
└── json-parser@2.1.0
    └── utf8@1.0.0

Features:

• Tree visualization with proper Unicode box-drawing
• Compact mode for simple listing
• Size-sorted view (shows largest packages first)
• Built from lock file data

Files Created:

• src/pkg/tree.zig - Dependency tree visualizer
  • DependencyTree - Tree builder and renderer
  • renderCompact() - Compact listing
  • renderWithSizes() - Sort by package size
  • buildFromLockFile() - Lock file integration

4. Workspace Support (Monorepos)

Status: ✅COMPLETE

Bun/pnpm-style workspaces for monorepos!

Configuration:

[package]
name = "my-monorepo"
version = "1.0.0"

[workspaces]
packages = [
  "packages/*",
  "apps/*"
]

Project Structure:

my-monorepo/
  ion.toml
  packages/
    http-router/
      ion.toml
    json-parser/
      ion.toml
  apps/
    web/
      ion.toml
    api/
      ion.toml

Features:

• Glob pattern matching (packages/*, apps/*)
• Automatic package discovery
• Workspace-wide installations
• Cross-workspace linking
• Run scripts in all packages

Files Created:

• src/pkg/workspace.zig - Complete workspace system
  • Workspace - Monorepo manager
  • WorkspacePackage - Individual package
  • Glob pattern matching
  • discover() - Find all packages
  • installAll() - Install all workspaces
  • linkPackages() - Link dependencies
  • runAll() - Run script in all packages

🚀 Enhanced Features

5. Parallel Downloads (Designed)

Status: 🟡Framework Ready

The infrastructure is in place for Bun-style parallel downloads:

What's Ready:

• Thread pool calculation (max 8 parallel downloads)
• Progress tracking for concurrent downloads
• Download queue management
• Speed aggregation across threads

What's Needed:

• Actual thread pool implementation
• Async download handlers
• Concurrent file system writes

Implementation Note: The downloadAll() function in package*manager.zig shows where parallel downloads will be implemented:

/// Download all dependencies (parallel like Bun!)
fn downloadAll(self: *PackageManager) !void {
    const num*threads = @min(num*packages, 8); // Max 8 parallel downloads
    std.debug.print("📦 Installing {d} packages ({d} parallel downloads)...\n",
        .{ num*packages, num*threads });

    // TODO: Implement actual parallel downloads with thread pool
}

📋 New CLI Commands

All commands are fully integrated into ion:
