# Universe 2025 Badge Deployment and File Management

Efficient workflows for deploying applications to **MonaOS**, managing files, and organizing projects on the Universe 2025 (Tufty) Badge.

## Deploying to MonaOS

MonaOS apps are **directories** in `/system/apps/`, not single files. Each app directory must contain:
- `__init__.py` - Entry point with `update()` function
- `icon.png` - 24x24 PNG icon for the launcher
- `assets/` - Optional directory for app resources

### ⚠️ CRITICAL: USB Mass Storage Mode Required

**The `/system/apps/` directory is READ-ONLY via mpremote.** You MUST use USB Mass Storage Mode to install, update, or delete apps.

```bash
# Step 1: Enter USB Mass Storage Mode
# - Connect badge via USB-C
# - Press RESET button TWICE quickly (double-click)
# - Badge appears as "BADGER" drive at /Volumes/BADGER (macOS)

# Step 2: Copy your app to the badge
cp -r my_app /Volumes/BADGER/apps/

# Or manually via Finder:
# - Open BADGER drive
# - Navigate to apps/ folder
# - Drag my_app folder into apps/

# Step 3: Exit Mass Storage Mode
diskutil eject /Volumes/BADGER  # Or eject via Finder
# Press RESET button once to reboot into MonaOS

# Your app will now appear in the MonaOS launcher!
```

**File System Mapping**:
- `/Volumes/BADGER/apps/` → `/system/apps/` on badge (MonaOS apps)
- `/Volumes/BADGER/assets/` → `/system/assets/` on badge (system resources)
- `/Volumes/BADGER/main.py` → `/system/main.py` on badge (boot script)

**⚠️ Important**: Install the paginated menu to show unlimited apps (default shows only 6):
- Download: https://raw.githubusercontent.com/badger/home/refs/heads/main/badge/apps/menu/__init__.py
- Replace `/Volumes/BADGER/apps/menu/__init__.py` in Mass Storage Mode

## File Transfer Methods

### Using mpremote for Development (NOT for installing apps)

**⚠️ IMPORTANT**: You CANNOT use `mpremote` to install apps to `/system/apps/` because it's read-only. Use Mass Storage Mode for apps.

`mpremote` is useful for:
- **Testing**: Running code temporarily without saving
- **App Data**: Copying files to `/storage/` (writable partition)
- **Development**: Quick iteration and debugging

```bash
# Run app temporarily (doesn't save to badge)
mpremote run my_app/__init__.py

# Copy app data to writable storage
mpremote cp data.txt :/storage/data.txt

# Create directory in writable storage
mpremote mkdir :/storage/mydata

# Copy from badge to computer
mpremote cp :/storage/data.txt local_backup.txt

# List files on badge
mpremote ls              # Root directory
mpremote ls /system/apps # MonaOS apps (read-only)
mpremote ls /storage     # Writable storage

# Remove file from storage (NOT /system/)
mpremote rm :/storage/data.txt

# Remove directory from storage (NOT /system/)
mpremote rm -rf :/storage/mydata
```

**What you CANNOT do with mpremote**:
- ❌ Install apps to `/system/apps/` (read-only)
- ❌ Modify `/system/apps/menu/` (read-only)
- ❌ Edit files in `/system/` (read-only)
- ✅ Use USB Mass Storage Mode instead for these operations

### Using ampy

```bash
# Install ampy
pip install adafruit-ampy

# Set port (or use --port flag)
export AMPY_PORT=/dev/tty.usbmodem*

# Upload file
ampy put main.py
ampy put config.py /lib/config.py

# Upload directory
ampy put lib/

# Download file
ampy get main.py

# List files
ampy ls
ampy ls /lib

# Remove file
ampy rm old_file.py
```

### Using rshell

```bash
# Install rshell
pip install rshell

# Connect
rshell --port /dev/tty.usbmodem*

# Commands in rshell
/your/computer> boards               # List connected boards
/your/computer> connect serial /dev/tty.usbmodem*
/your/computer> cp main.py /pyboard/
/your/computer> cp -r lib /pyboard/
/your/computer> ls /pyboard
/your/computer> cat /pyboard/main.py
/your/computer> rm /pyboard/old.py
```

### Manual File Sync via REPL

```python
# In REPL - create/edit file directly
f = open('config.py', 'w')
f.write('''
CONFIG = {
    'wifi_ssid': 'MyNetwork',
    'wifi_password': 'password123',
    'version': '1.0.0'
}
''')
f.close()
```

## Project Organization

### MonaOS App Structure

Each MonaOS app is a **directory** with this structure:

```
my_app/                  # Your app directory
├── __init__.py          # Entry point with update() function (required)
├── icon.png             # 24x24 PNG icon for launcher (required)
├── assets/              # Optional: app resources (auto-added to path)
│   ├── sprites.png
│   ├── font.ppf
│   └── config.json
└── README.md            # Optional: app documentation
```

### Local Development Structure

Your development directory on your computer:

```
badge-project/
├── my_app/              # MonaOS app directory
│   ├── __init__.py      # App entry point
│   ├── icon.png         # 24x24 icon
│   └── assets/          # App assets
│       └── sprites.png
├── another_app/         # Another MonaOS app
│   ├── __init__.py
│   └── icon.png
├── requirements.txt     # Python dependencies for development
├── venv/                # Virtual environment
└── deploy.sh            # Deployment script
```

### Deploy Script for MonaOS Apps

**⚠️ IMPORTANT**: Since `/system/apps/` is read-only via mpremote, this script uses USB Mass Storage Mode.

Create `deploy.sh`:

```bash
#!/bin/bash
# deploy.sh - Deploy MonaOS app to badge via USB Mass Storage Mode

if [ -z "$1" ]; then
    echo "Usage: ./deploy.sh <app_name>"
    echo "Example: ./deploy.sh my_app"
    exit 1
fi

APP_NAME=$1
BADGE_MOUNT="/Volumes/BADGER"

if [ ! -d "$APP_NAME" ]; then
    echo "Error: App directory '$APP_NAME' not found"
    exit 1
fi

# Check if badge is in Mass Storage Mode
if [ ! -d "$BADGE_MOUNT" ]; then
    echo "⚠️  Badge not found in Mass Storage Mode"
    echo ""
    echo "Please enter Mass Storage Mode:"
    echo "  1. Connect badge via USB-C"
    echo "  2. Press RESET button TWICE quickly"
    echo "  3. Wait for BADGER drive to appear"
    echo "  4. Run this script again"
    exit 1
fi

echo "Deploying $APP_NAME to MonaOS..."

# Verify required files exist
if [ ! -f "$APP_NAME/__init__.py" ]; then
    echo "Error: __init__.py not found in $APP_NAME/"
    exit 1
fi

if [ ! -f "$APP_NAME/icon.png" ]; then
    echo "Warning: icon.png not found (required for launcher display)"
fi

# Remove old version if it exists
if [ -d "$BADGE_MOUNT/apps/$APP_NAME" ]; then
    echo "Removing old version..."
    rm -rf "$BADGE_MOUNT/apps/$APP_NAME"
fi

# Copy app to badge
echo "Copying app to badge..."
cp -r "$APP_NAME" "$BADGE_MOUNT/apps/"

echo "✓ Deployment complete!"
echo ""
echo "Next steps:"
echo "  1. Eject BADGER drive: diskutil eject /Volumes/BADGER"
echo "  2. Press RESET once on badge to reboot"
echo "  3. Your app will appear in MonaOS launcher"
echo ""
echo "Note: Install paginated menu for unlimited apps:"
echo "https://raw.githubusercontent.com/badger/home/refs/heads/main/badge/apps/menu/__init__.py"
```

Make executable: `chmod +x deploy.sh`

Usage:
```bash
./deploy.sh my_app
```

## Deployment Workflows

### Development Workflow

Quick iteration during development:

```bash
# 1. Edit code locally
vim my_app/__init__.py

# 2. Test app temporarily (doesn't save to badge)
mpremote run my_app/__init__.py

# 3. Deploy to MonaOS launcher (use Mass Storage Mode)
# - Press RESET twice on badge
# - Copy updated files: cp -r my_app /Volumes/BADGER/apps/
# - Eject and press RESET once

# 4. Verify deployment
mpremote ls /system/apps/my_app

# 5. Launch from badge
# Use physical buttons to navigate MonaOS menu and select your app
```

### Production Deployment

Full deployment with verification:

```bash
#!/bin/bash
# production-deploy.sh

set -e  # Exit on error

BADGE_PORT="/dev/tty.usbmodem*"

echo "Starting production deployment..."

# Backup existing files
echo "Creating backup..."
mpremote connect $BADGE_PORT cp :main.py :main.py.backup
mpremote connect $BADGE_PORT cp :config.py :config.py.backup

# Deploy new files
echo "Deploying new version..."
mpremote connect $BADGE_PORT cp main.py :main.py
mpremote connect $BADGE_PORT cp config.py :config.py
mpremote connect $BADGE_PORT cp -r lib/ :/lib/

# Verify deployment
echo "Verifying deployment..."
mpremote connect $BADGE_PORT exec "
import sys
print('MicroPython version:', sys.version)

# Import and verify main module
try:
    import main
    print('✓ main.py imports successfully')
except Exception as e:
    print('✗ Error importing main.py:', e)
    sys.exit(1)
"

# Restart with new code
echo "Restarting badge..."
mpremote connect $BADGE_PORT exec "import machine; machine.soft_reset()"

echo "Production deployment complete!"
```

### Staged Deployment

Test on one badge before deploying to multiple:

```bash
#!/bin/bash
# staged-deploy.sh

# Stage 1: Deploy to test badge
echo "Stage 1: Deploying to test badge..."
./deploy.sh --port /dev/tty.usbmodem1

# Stage 2: Run automated tests
echo "Stage 2: Running tests..."
python test_suite.py --badge /dev/tty.usbmodem1

# Stage 3: Deploy to production badges
echo "Stage 3: Deploying to all badges..."
for port in /dev/tty.usbmodem*; do
    echo "Deploying to $port..."
    ./deploy.sh --port $port
done

echo "Staged deployment complete!"
```

## File Management

### Sync Local and Badge Files

```python
# sync.py - Sync files between computer and badge
import os
import subprocess
import hashlib

def get_local_files(path='.'):
    """Get list of local .py files"""
    files = []
    for root, dirs, filenames in os.walk(path):
        # Skip test directories
        if 'test' in root:
            continue
        for filename in filenames:
            if filename.endswith('.py'):
                filepath = os.path.join(root, filename)
                files.append(filepath)
    return files

def sync_to_badge(port='/dev/tty.usbmodem*'):
    """Sync all Python files to badge"""
    files = get_local_files()

    print(f"Syncing {len(files)} files to badge...")
    for filepath in files:
        # Determine badge path
        if filepath.startswith('./lib/'):
            badge_path = f":/{filepath[2:]}"
        elif filepath.startswith('./'):
            badge_path = f":/{filepath[2:]}"
        else:
            badge_path = f":/{filepath}"

        # Upload file
        cmd = f"mpremote connect {port} cp {filepath} {badge_path}"
        print(f"  {filepath} -> {badge_path}")
        subprocess.run(cmd, shell=True, check=True)

    print("Sync complete!")

if __name__ == '__main__':
    sync_to_badge()
```

### Clean Up Badge Files

```python
# cleanup.py - Remove unused files from badge

def cleanup_badge():
    """Remove temporary and cache files from badge"""
    import os

    # Files to remove
    patterns = [
        '.pyc',      # Compiled Python
        '.backup',   # Backup files
        '.tmp',      # Temporary files
        'debug_',    # Debug files
    ]

    removed = []

    for path in ['/', '/lib']:
        try:
            files = os.listdir(path)
            for file in files:
                # Check if file matches cleanup pattern
                if any(file.endswith(p) or file.startswith(p) for p in patterns):
                    filepath = f"{path}/{file}".replace('//', '/')
                    os.remove(filepath)
                    removed.append(filepath)
        except:
            pass

    print(f"Cleanup complete! Removed {len(removed)} files:")
    for f in removed:
        print(f"  {f}")

# Run on badge via mpremote:
# mpremote exec "$(cat cleanup.py)"
```

### List Badge Files

```bash
# list_files.sh - Comprehensive file listing

echo "Files on badge:"
echo "==============="

echo -e "\nRoot directory:"
mpremote ls

echo -e "\n/lib directory:"
mpremote ls /lib 2>/dev/null || echo "  (not found)"

echo -e "\n/assets directory:"
mpremote ls /assets 2>/dev/null || echo "  (not found)"

echo -e "\n/data directory:"
mpremote ls /data 2>/dev/null || echo "  (not found)"
```

## Backup and Restore

### Backup Badge to Computer

```bash
#!/bin/bash
# backup.sh - Backup all files from badge

BACKUP_DIR="backup_$(date +%Y%m%d_%H%M%S)"
mkdir -p "$BACKUP_DIR"

echo "Backing up badge to $BACKUP_DIR..."

# Backup root Python files
for file in $(mpremote ls | grep '.py'); do
    echo "  Backing up $file..."
    mpremote cp ":$file" "$BACKUP_DIR/$file"
done

# Backup lib directory
mkdir -p "$BACKUP_DIR/lib"
for file in $(mpremote ls /lib 2>/dev/null | grep '.py'); do
    echo "  Backing up /lib/$file..."
    mpremote cp ":/lib/$file" "$BACKUP_DIR/lib/$file"
done

echo "Backup complete: $BACKUP_DIR"
```

### Restore Badge from Backup

```bash
#!/bin/bash
# restore.sh - Restore files to badge from backup

if [ -z "$1" ]; then
    echo "Usage: ./restore.sh <backup_directory>"
    exit 1
fi

BACKUP_DIR=$1

echo "Restoring from $BACKUP_DIR..."

# Restore root files
for file in "$BACKUP_DIR"/*.py; do
    if [ -f "$file" ]; then
        filename=$(basename "$file")
        echo "  Restoring $filename..."
        mpremote cp "$file" ":$filename"
    fi
done

# Restore lib directory
if [ -d "$BACKUP_DIR/lib" ]; then
    mpremote mkdir /lib 2>/dev/null || true
    for file in "$BACKUP_DIR/lib"/*.py; do
        if [ -f "$file" ]; then
            filename=$(basename "$file")
            echo "  Restoring /lib/$filename..."
            mpremote cp "$file" ":/lib/$filename"
        fi
    done
fi

echo "Restore complete!"
```

## Version Management

### Version File

Create `version.py` on badge:

```python
# version.py
VERSION = '1.2.3'
BUILD_DATE = '2024-01-15'
COMMIT = 'abc123f'

def show():
    print(f"Version: {VERSION}")
    print(f"Build: {BUILD_DATE}")
    print(f"Commit: {COMMIT}")
```

### Auto-generate Version

```bash
#!/bin/bash
# generate_version.sh - Auto-generate version file

VERSION=$(git describe --tags --always)
BUILD_DATE=$(date +%Y-%m-%d)
COMMIT=$(git rev-parse --short HEAD)

cat > version.py <<EOF
# Auto-generated version file
VERSION = '$VERSION'
BUILD_DATE = '$BUILD_DATE'
COMMIT = '$COMMIT'
EOF

echo "Generated version.py: $VERSION ($BUILD_DATE)"
```

Add to deploy script:

```bash
# Generate version before deploy
./generate_version.sh
mpremote cp version.py :version.py
```

## Multi-Badge Deployment

### Deploy to Multiple Badges

```bash
#!/bin/bash
# multi-deploy.sh - Deploy to multiple connected badges

echo "Scanning for connected badges..."
BADGES=$(ls /dev/tty.usbmodem* 2>/dev/null)

if [ -z "$BADGES" ]; then
    echo "No badges found!"
    exit 1
fi

echo "Found badges:"
echo "$BADGES"
echo

read -p "Deploy to all? (y/n) " -n 1 -r
echo
if [[ ! $REPLY =~ ^[Yy]$ ]]; then
    exit 0
fi

for PORT in $BADGES; do
    echo "================================"
    echo "Deploying to $PORT..."
    echo "================================"

    mpremote connect $PORT cp main.py :main.py
    mpremote connect $PORT cp config.py :config.py
    mpremote connect $PORT cp -r lib/ :/lib/

    echo "✓ Deployed to $PORT"
    echo
done

echo "All badges updated!"
```

## CI/CD Integration

### GitHub Actions Example

```yaml
# .github/workflows/deploy.yml
name: Deploy to Badge

on:
  push:
    branches: [ main ]

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      - name: Set up Python
        uses: actions/setup-python@v4
        with:
          python-version: '3.11'

      - name: Install dependencies
        run: |
          pip install mpremote pytest

      - name: Run tests
        run: |
          pytest tests/

  deploy:
    needs: test
    runs-on: self-hosted  # Runner with badge connected
    steps:
      - uses: actions/checkout@v3

      - name: Deploy to badge
        run: |
          ./generate_version.sh
          ./deploy.sh
```

### Pre-commit Hook

```bash
# .git/hooks/pre-commit
#!/bin/bash
# Run tests before allowing commit

echo "Running tests..."
python -m pytest tests/

if [ $? -ne 0 ]; then
    echo "Tests failed! Commit aborted."
    exit 1
fi

echo "Tests passed!"
exit 0
```

Make executable: `chmod +x .git/hooks/pre-commit`

## Hot Reload Development

### Watch and Auto-deploy

```python
# watch.py - Watch for file changes and auto-deploy
import time
import os
import subprocess
from pathlib import Path

def get_file_hash(filepath):
    """Get hash of file contents"""
    import hashlib
    with open(filepath, 'rb') as f:
        return hashlib.md5(f.read()).hexdigest()

def watch_and_deploy(watch_files, port='/dev/tty.usbmodem*'):
    """Watch files and deploy on change"""
    print(f"Watching {len(watch_files)} files for changes...")

    file_hashes = {f: get_file_hash(f) for f in watch_files}

    try:
        while True:
            time.sleep(1)  # Check every second

            for filepath in watch_files:
                current_hash = get_file_hash(filepath)

                if current_hash != file_hashes[filepath]:
                    print(f"\n{filepath} changed! Deploying...")

                    # Deploy changed file
                    badge_path = f":/{filepath}"
                    cmd = f"mpremote connect {port} cp {filepath} {badge_path}"
                    subprocess.run(cmd, shell=True)

                    # Soft reset badge
                    cmd = f"mpremote connect {port} exec 'import machine; machine.soft_reset()'"
                    subprocess.run(cmd, shell=True)

                    # Update hash
                    file_hashes[filepath] = current_hash

                    print("Deploy complete!")
    except KeyboardInterrupt:
        print("\nStopped watching.")

if __name__ == '__main__':
    watch_files = ['main.py', 'config.py', 'lib/display.py']
    watch_and_deploy(watch_files)
```

## Best Practices

### Pre-deployment Checklist

- [ ] Test code locally (if possible)
- [ ] Update version number
- [ ] Run linter/formatter
- [ ] Commit changes to git
- [ ] Backup current badge code
- [ ] Deploy to test badge first
- [ ] Verify deployment success
- [ ] Test on badge
- [ ] Deploy to production badges

### File Organization Tips

1. **Keep main.py simple** - Import from modules
2. **Use /lib for reusable code** - Separate concerns
3. **Store data in /data** - Keep code and data separate
4. **Version control everything** - Except secrets
5. **Use .gitignore** - Don't commit badge-specific configs

### Deployment Optimization

```bash
# Minimize deployment time

# Deploy only changed files
git diff --name-only HEAD~1 | grep '.py$' | while read file; do
    mpremote cp "$file" ":/$file"
done

# Compress files before transfer (if network-based)
# gzip files, transfer, decompress on badge

# Parallel deployment to multiple badges
parallel -j 4 ./deploy.sh --port ::: /dev/tty.usbmodem*
```

## Troubleshooting Deployment

**Files not updating**: Verify file was actually copied, check paths with `mpremote ls /system/apps/my_app`

**Permission denied**: Badge may be in use by another process, close other connections

**Deployment fails silently**: Check disk space on badge, verify file syntax, ensure `__init__.py` and `icon.png` exist

**App doesn't appear in MonaOS menu**:
- Verify files uploaded to `/system/apps/my_app/`
- Check icon is exactly 24x24 PNG
- Default menu shows only 6 apps - enable pagination: https://badger.github.io/hack/menu-pagination/

**Changes not reflected**: Restart badge to reload app code

**Slow transfers**: USB cable quality matters, try different cable/port
