# 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
|
||||
```
