# CLAUDE.md - AI Assistant Reference Guide
This document provides comprehensive project information for AI assistants (like Claude) working on the Renamer project.
## Project Overview
**Renamer** is a sophisticated Terminal User Interface (TUI) application for managing, viewing metadata, and renaming media files. Built with Python and the Textual framework, it provides an interactive, curses-like interface for media collection management.
### Current Version
- **Version**: 0.5.10
- **Python**: 3.11+
- **Status**: Active development with media catalog mode features
## Project Purpose
Renamer serves two primary use cases:
1. **Technical Mode**: Detailed technical metadata viewing (video tracks, audio streams, codecs, bitrates)
2. **Catalog Mode**: Media library catalog view with TMDB integration (posters, ratings, descriptions, genres)
## Architecture Overview
### Core Components
#### Main Application (`renamer/app.py`)
- Main `RenamerApp` class inheriting from Textual's `App`
- Manages TUI layout with split view: file tree (left) and details panel (right)
- Handles keyboard/mouse navigation and user commands
- Coordinates file operations and metadata extraction
- Implements efficient tree updates for file renaming
#### Entry Point (`renamer/main.py`)
- Argument parsing for directory selection
- Application initialization and launch
#### Constants (`renamer/constants.py`)
Defines comprehensive dictionaries:
- `MEDIA_TYPES`: Supported video formats (mkv, avi, mov, mp4, etc.)
- `SOURCE_DICT`: Video source types (WEB-DL, BDRip, BluRay, etc.)
- `FRAME_CLASSES`: Resolution classifications (480p-8K)
- `MOVIE_DB_DICT`: Database identifiers (TMDB, IMDB, Trakt, TVDB)
- `SPECIAL_EDITIONS`: Edition types (Director's Cut, Extended, etc.)
### Extractor System (`renamer/extractors/`)
Modular architecture for gathering metadata from multiple sources:
#### Core Extractors
1. **MediaInfoExtractor** (`mediainfo_extractor.py`)
- Uses PyMediaInfo library
- Extracts detailed track information (video, audio, subtitle)
- Provides codec, bitrate, frame rate, resolution data
2. **FilenameExtractor** (`filename_extractor.py`)
- Parses metadata from filename patterns
- Detects year, resolution, source, codecs, edition info
- Uses regex patterns to extract structured data
3. **MetadataExtractor** (`metadata_extractor.py`)
- Reads embedded metadata using Mutagen
- Extracts tags, container format info
4. **FileInfoExtractor** (`fileinfo_extractor.py`)
- Basic file information (size, dates, permissions)
- MIME type detection via python-magic
5. **TMDBExtractor** (`tmdb_extractor.py`)

- Color-coded track information
4. **ProposedNameFormatter** (`proposed_name_formatter.py`)
- Generates intelligent rename suggestions
- Pattern: `Title (Year) [Resolution Source Edition].ext`
- Sanitizes filenames (removes invalid characters)
5. **Utility Formatters**
- `SizeFormatter`: Human-readable file sizes
- `DateFormatter`: Timestamp formatting
- `DurationFormatter`: Duration in HH:MM:SS
- `ResolutionFormatter`: Resolution display
- `TextFormatter`: Text styling utilities
- `ExtensionFormatter`: File extension handling
- `SpecialInfoFormatter`: Edition/source formatting

# Enable formatter logging
FORMATTER_LOG=1 uv run renamer /path/to/directory
# Creates formatter.log with detailed call traces
```
### Testing
- Test files in `renamer/test/`
- Sample filenames in `test/filenames.txt` and `test/test_filenames.txt`
- Test cases in `test/test_cases.json`
- Run with: `uv run pytest`
## Code Style & Standards
### Python Standards
- Type hints encouraged
- PEP 8 style guidelines
- Descriptive variable/function names
- Docstrings for classes and functions
- Pathlib for file operations
- Proper exception handling
### Architecture Patterns
- Extractor pattern: Each extractor focuses on one data source
- Formatter pattern: Formatters handle display logic, extractors handle data
- Separation of concerns: Data extraction → formatting → display
- Dependency injection: Extractors and formatters are modular
- Configuration management: Settings class for all config
### Best Practices
- Avoid over-engineering (keep solutions simple)
- Only add features when explicitly requested
- Validate at system boundaries only (user input, external APIs)
- Don't add unnecessary error handling for internal code
- Trust framework guarantees
- Delete unused code completely (no backwards-compat hacks)
## File Operations
### Directory Scanning
- Recursive search for supported video formats
- File tree representation with hierarchical structure
- Efficient tree updates on file operations
### File Renaming
1. Select file in tree
2. Press `r` to initiate rename
3. Review proposed name (shows current vs proposed)
4. Confirm with `y` or cancel with `n`
5. Tree updates in-place without full reload
### Metadata Caching
- First extraction cached for 6 hours
- TMDB data cached for 6 hours
- Posters cached for 30 days
- Force refresh with `f` command
- Cache invalidated on file rename
## API Integration
### TMDB API
- API key stored in `renamer/secrets.py`
- Search endpoint for movie lookup by title/year
- Image base URL for poster downloads
- Handles rate limiting and errors gracefully
- Falls back to filename data if API unavailable
## Project Files
### Documentation
- `README.md`: User-facing documentation
- `AI_AGENT.md`: AI agent instructions (legacy)
- `DEVELOP.md`: Developer guide
- `INSTALL.md`: Installation instructions
- `ToDo.md`: Task tracking

## Contributing Guidelines
### Making Changes
1. Read existing code and understand architecture
2. Check `ToDo.md` for pending tasks
3. Implement features incrementally
4. Test with real media files
5. Ensure backward compatibility
6. Update documentation
7. Update tests as needed
8. Run `uv run release` before committing
### Commit Standards
- Clear, descriptive commit messages
- Focus on "why" not "what"
- One logical change per commit
- Reference related issues/tasks
### Code Review Checklist
- [ ] Follows PEP 8 style
- [ ] Type hints added where appropriate
- [ ] No unnecessary complexity
- [ ] Tests pass (`uv run pytest`)
- [ ] Documentation updated
- [ ] No security vulnerabilities (XSS, injection, etc.)
- [ ] Efficient resource usage (no memory leaks)
## Security Considerations
- Input sanitization for filenames (see `ProposedNameFormatter`)
- No shell command injection risks
- Safe file operations (pathlib, proper error handling)
- TMDB API key should not be committed (stored in `secrets.py`)
- Cache directory permissions should be user-only
## Performance Notes
- In-memory cache reduces repeated extraction overhead
- File cache persists across sessions
- Tree updates optimized for rename operations
- TMDB requests throttled to respect API limits
- Large directory scans use async/await patterns
## Special Notes for AI Assistants
### When Adding Features
1. **Always read relevant files first** - Never modify code you haven't read
2. **Check ToDo.md** - See if feature is already planned
3. **Understand existing patterns** - Follow established architecture
4. **Test with real files** - Use actual media files for testing
5. **Update documentation** - Keep docs in sync with code
### When Debugging
1. **Enable formatter logging** - Use `FORMATTER_LOG=1` for detailed traces
2. **Check cache state** - Clear cache if stale data suspected
3. **Verify file permissions** - Ensure read/write access
4. **Test with sample filenames** - Use test fixtures first
### When Refactoring
1. **Maintain backward compatibility** - Unless explicitly breaking change
2. **Update tests** - Reflect refactored code
3. **Check all formatters** - Formatting is centralized
4. **Verify extractor chain** - Ensure data flow intact
### Common Pitfalls to Avoid
- Don't create new files unless absolutely necessary (edit existing)
- Don't add features beyond what's requested
- Don't over-engineer solutions
- Don't skip testing with real files
- Don't forget to update version number for releases
- Don't commit secrets or API keys
- Don't use deprecated Textual APIs

**Version**: 0.5.10
## Features ## Features
- Recursive directory scanning for video files ### Core Capabilities
- Tree view navigation with keyboard and mouse support - **Dual Display Modes**: Switch between Technical (codec/track details) and Catalog (TMDB metadata with posters)
- Detailed metadata extraction from multiple sources (MediaInfo, filename parsing, embedded metadata) - **Recursive Directory Scanning**: Finds all video files in nested directories
- Intelligent file renaming with proposed names based on metadata - **Tree View Navigation**: Keyboard and mouse support with expand/collapse
- Color-coded information display - **Multi-Source Metadata**: Combines MediaInfo, filename parsing, embedded tags, and TMDB API
- Command-based interface with hotkeys - **Intelligent Renaming**: Proposes standardized names based on extracted metadata
- Extensible extractor and formatter system - **Persistent Settings**: Configurable mode and cache TTLs saved to `~/.config/renamer/`
- Support for video, audio, and subtitle track information - **Advanced Caching**: File-based cache with TTL (6h extractors, 6h TMDB, 30d posters)
- Confirmation dialogs for file operations - **Terminal Poster Display**: View movie posters in your terminal using rich-pixels
- **Color-Coded Display**: Visual highlighting for different data types
- **Confirmation Dialogs**: Safe file operations with preview and confirmation
- **Extensible Architecture**: Modular extractor and formatter system for easy extension
