# Plex Library Scanner Implementation Summary

## Overview
Successfully implemented a comprehensive Plex library scanning solution based on the Plex Media Scanner CLI documentation. The implementation provides both standalone functionality and seamless integration with the existing plex.sh management script.

## Implementation Details

### 1. New Script: `scan-plex-libraries.sh`

**Location**: `/home/acedanger/shell/plex/scan-plex-libraries.sh`

**Features Implemented**:
- ✅ **Library Listing**: Lists all Plex libraries with section IDs and names
- ✅ **Library Scanning**: Scan for new media (individual or all libraries)
- ✅ **Metadata Refresh**: Refresh library metadata with force option
- ✅ **Media Analysis**: Analyze media files (standard and deep analysis)
- ✅ **Thumbnail Generation**: Generate thumbnails and fanart
- ✅ **Library Tree**: Display hierarchical library structure
- ✅ **Interactive Mode**: User-friendly menu system
- ✅ **Verbose Logging**: Detailed operation logging
- ✅ **Error Handling**: Comprehensive validation and error reporting
- ✅ **Service Validation**: Checks Plex service status before operations
- ✅ **Scanner Detection**: Automatically finds Plex Media Scanner binary

**Command Examples**:
```bash
# List all libraries
./scan-plex-libraries.sh list

# Scan specific library
./scan-plex-libraries.sh scan 29

# Force refresh all libraries
./scan-plex-libraries.sh refresh "" true

# Deep analyze specific library
./scan-plex-libraries.sh analyze 29 true

# Generate thumbnails for library
./scan-plex-libraries.sh generate 29

# Interactive mode
./scan-plex-libraries.sh
```

### 2. Integration with `plex.sh`

**Changes Made**:
- ✅ Added `scan` command to main case statement
- ✅ Added `launch_scanner()` function for integration
- ✅ Updated help documentation to include scan command
- ✅ Updated script header documentation
- ✅ Supports argument passthrough to scanner script

**Integration Examples**:
```bash
# Launch interactive scanner
./plex.sh scan

# Pass commands directly to scanner
./plex.sh scan list
./plex.sh scan scan 29
./plex.sh scan refresh "" true
```

### 3. New Aliases

**Added to `/home/acedanger/shell/dotfiles/my-aliases.zsh`**:
```bash
alias plex-scan="/home/acedanger/shell/plex/plex.sh scan"        # Library scanner via plex.sh
alias plex-scanner="/home/acedanger/shell/plex/scan-plex-libraries.sh"  # Direct scanner access
```

**Usage Examples**:
```bash
plex-scan              # Launch scanner via plex.sh
plex-scanner list      # Direct scanner access to list libraries
plex-scanner scan 29   # Direct scan of specific library
```

### 4. Documentation

**Created**:
- ✅ **Comprehensive Documentation**: `/home/acedanger/shell/plex/docs/plex-library-scanner.md`
- ✅ **Updated Main README**: Added scanner section to `/home/acedanger/shell/plex/README.md`

**Documentation Includes**:
- Complete usage guide with examples
- Command reference with parameters
- Integration examples
- Troubleshooting guide
- Best practices
- Performance considerations

## Key Features

### Automatic Scanner Detection
The script automatically detects the Plex Media Scanner binary from common locations:
- `/usr/lib/plexmediaserver/Plex Media Scanner` (Linux - most common)
- `/opt/plex/Plex Media Scanner`
- `/usr/local/plex/Plex Media Scanner`
- `/Applications/Plex Media Server.app/Contents/MacOS/Plex Media Scanner` (macOS)
- System PATH

### Comprehensive Error Handling
- Service status validation (Plex must be running)
- Scanner binary detection and validation
- Section ID validation against actual libraries
- Operation failure detection and reporting
- Graceful error recovery

### Interactive Mode
Full-featured interactive menu system with:
- Library listing and selection
- Operation choice with sub-menus
- Force/deep options for advanced operations
- User-friendly prompts and confirmations

### Logging and Debugging
- Detailed logging to `/home/acedanger/shell/logs/plex-scanner.log`
- Verbose mode for debugging (`-v` flag)
- Timestamp-based log entries
- Operation success/failure tracking

## Based on Plex CLI Documentation

Implementation follows the official Plex Media Scanner CLI documentation:
- Uses standard Plex scanner commands (`--list`, `--scan`, `--refresh`, etc.)
- Proper section ID handling
- Force flags for metadata refresh
- Deep analysis options
- Thumbnail generation capabilities

## Testing Results

### ✅ Syntax Validation
```bash
$ bash -n ./scan-plex-libraries.sh
$ bash -n ./plex.sh
# Both scripts pass syntax validation
```

### ✅ Help System
```bash
$ ./plex.sh help
# Shows new scan command in help output

$ ./scan-plex-libraries.sh --help
# Shows comprehensive usage information
```

### ✅ Error Handling
```bash
$ ./scan-plex-libraries.sh list
# Correctly detects Plex service not running
# Provides helpful error message with resolution
```

### ✅ Integration
```bash
$ ./plex.sh scan --help
# Successfully launches scanner with arguments
# Proper argument passthrough working
```
