# Karaoke Song Library Cleanup Tool - CLI Commands Reference (v2.0)

## Overview
The CLI tool analyzes karaoke song collections, identifies duplicates, validates playlists, and generates skip lists for future imports. It supports multiple file formats (MP3, CDG, MP4) with configurable priority systems.

## Quick Start Commands

### Basic Analysis (Most Common)
```bash
cd cli
python3 main.py
```
Runs the tool with default settings:
- Input: `data/songs.json`
- Config: `config/config.json`
- Output: `data/skipSongs.json`
- Reports: **Automatically generated**

### Process Everything (Recommended)
```bash
cd cli
python3 main.py --process-all
```
Complete processing including:
- Duplicate analysis and skip list generation
- Favorites processing with priority logic (MP4 over MP3)
- History processing with priority logic
- Comprehensive report generation

## Main CLI Commands (main.py)

### Basic Analysis Commands

#### Standard Analysis
```bash
python3 main.py
```
Runs the tool with default settings and generates all reports automatically.

#### Verbose Output
```bash
python3 main.py --verbose
# or
python3 main.py -v
```
Enables detailed output showing individual song processing and decisions.

#### Dry Run Mode
```bash
python3 main.py --dry-run
```
Analyzes songs without generating the skip list file. Useful for testing and previewing results.

### Configuration Commands

#### Custom Configuration File
```bash
python3 main.py --config path/to/custom_config.json
```
Uses a custom configuration file instead of the default `config/config.json`.

#### Show Current Configuration
```bash
python3 main.py --show-config
```
Displays the current configuration settings and exits.

### Input/Output Commands

#### Custom Input File
```bash
python3 main.py --input path/to/songs.json
```
Specifies a custom input file instead of the default `data/songs.json`.

#### Custom Output Directory
```bash
python3 main.py --output-dir ./custom_output
```
Saves output files to a custom directory instead of the default `data/` folder.

### Processing Commands

#### Process Favorites Only
```bash
python3 main.py --process-favorites
```
Processes favorites with priority-based logic to select best versions (MP4 over MP3).

#### Process History Only
```bash
python3 main.py --process-history
```
Processes history with priority-based logic to select best versions (MP4 over MP3).

#### Process Everything
```bash
python3 main.py --process-all
```
Processes everything: duplicates, generates reports, AND updates favorites/history with priority logic.

#### Merge History Objects
```bash
python3 main.py --merge-history
```
Merges history objects that match on artist, title, and path, summing their count properties.

### Report Generation

#### Save Detailed Reports (Legacy)
```bash
python3 main.py --save-reports
```
**Note**: Reports are now automatically generated every time you run the CLI tool. This flag is kept for backward compatibility.

Generated reports include:
- `enhanced_summary_report.txt` - Comprehensive analysis
- `channel_optimization_report.txt` - Priority optimization suggestions
- `duplicate_pattern_report.txt` - Duplicate pattern analysis
- `actionable_insights_report.txt` - Recommendations and insights
- `detailed_duplicate_analysis.txt` - Specific songs and their duplicates
- `analysis_data.json` - Raw analysis data for further processing
- `skip_songs_detailed.json` - **Web UI data (always generated)**

## Playlist Validator Commands (playlist_validator.py)

### Basic Playlist Validation

#### Validate All Playlists
```bash
python3 playlist_validator.py
```
Validates all playlists in `data/songList.json` against the song library.

#### Validate Specific Playlist
```bash
python3 playlist_validator.py --playlist-index 0
```
Validates a specific playlist by index (0-based).

### Playlist Validator Options

#### Custom Configuration
```bash
python3 playlist_validator.py --config path/to/custom_config.json
```
Uses a custom configuration file.

#### Custom Data Directory
```bash
python3 playlist_validator.py --data-dir path/to/data
```
Uses a custom data directory.

#### Apply Changes (Disable Dry Run)
```bash
python3 playlist_validator.py --apply
```
Applies changes to playlists instead of just previewing them.

#### Output Results to File
```bash
python3 playlist_validator.py --output results.json
```
Saves validation results to a JSON file.

#### 6. Apply History Merging
```bash
cd cli
python3 main.py --merge-history
```
Actually merge history objects:
- Combines duplicate history entries
