These guidelines capture the principles and patterns established during the refactor. + +## Architecture & Design + +### Modular Structure + +Separate concerns into dedicated modules: + +- **Game Logic** (`snake.py`) - Core game loop and UI interaction +- **Constants** (`constants.py`) - Game configuration and magic numbers +- **Themes** (`theme.py`) - Color and UI styling +- **Sound** (`sound_manager.py`) - Audio effects and music (runs in separate process) +- **Persistence** (`high_score.py`, `game_config.py`) - Data storage and retrieval + +**Pattern**: Each module has a single responsibility. Avoid mixing config, logic, and I/O. + +**Example**: Don't hardcode speed values in the game loop—define them in `constants.py` and import them. + +### Configuration Management + +Use JSON files in the home directory for user preferences and data: + +- `~/.snake_config.json` - User settings (speed, length, theme, effects) +- `~/.snake_scores.json` - High scores and game history + +**Pattern**: Create dedicated manager classes (`GameConfig`, `HighScoreManager`) to handle persistence. + +**Benefits**: Settings persist across sessions, users can manually edit configs, no directory pollution. + +## Code Style & Quality + +### Type Hints + +Use comprehensive type hints on all functions: + +```python +def ask_question( + self, + question: str, + value_type: type, + value_default, + value_min: int = 0, + value_max: int = 0 +): + """Ask user a question and validate the response.""" +``` + +**When**: Every function parameter and return type. +**Why**: Enables better IDE support, catches bugs early, improves readability. + +### Docstrings + +Add docstrings to all modules, classes, and methods: + +```python +def _handle_input(self, current_key: int, next_key: int) -> Optional[int]: + """Handle player input and return new direction, or None if quitting.""" +``` + +**Pattern**: One-liner for simple functions; paragraph for complex logic explaining intent and side effects. + +### Error Handling & Graceful Degradation + +When optional features fail (missing files, audio init), gracefully continue: + +```python +def _load_effects(self) -> None: + """Load all sound effects.""" + for effect_name, filename in effect_files.items(): + effect_path = self.effects_dir / filename + try: + if effect_path.exists(): + self.sounds[effect_name] = pygame.mixer.Sound(str(effect_path)) + except pygame.error as e: + print(f"Warning: Could not load effect {filename}: {e}") +``` + +**Pattern**: Try to load optional features; warn but don't crash if they're missing. + +### File Paths + +Always use absolute paths with `pathlib.Path`: + +```python +from pathlib import Path + +self.effects_dir = Path(__file__).parent / 'effects' +self.music_dir = Path(__file__).parent / 'music' +``` + +**Why**: Works regardless of where the script is invoked from. Relative paths break when run from different directories. + +### Input Validation + +Use loops instead of recursion to avoid stack overflow: + +```python +while True: + # ... get input ... + if value_type == int: + try: + answer = int(answer) + if value_min <= answer <= value_max: + return answer + except ValueError: + pass + # Show error and retry (not recursive call) + self.print_center(f"ERROR: Must be {value_min}-{value_max}", 1, color) + time.sleep(2) +``` + +**Why**: Recursive validation can stack overflow on repeated bad input. + +### Code Cleanliness + +- Remove unnecessary semicolons (Python style) +- Remove commented-out code—if needed, use version control +- Use f-strings instead of `.format()` or `%` formatting +- Avoid `Any` type hints—be specific: `List[int]`, `Optional[str]`, etc. + +## CLI Arguments & Configuration + +When adding user-facing options, use `argparse`: + +```python +def parse_args() -> argparse.Namespace: + """Parse command-line arguments.""" + parser = argparse.ArgumentParser(description='Snake CLI Game') + parser.add_argument( + '--music', + action='store_true', + help='Enable background music' + ) + return parser.parse_args() +``` + +**Pattern**: Arguments override saved preferences; save user choices back to config. + +## Process Management + +When spawning background processes (audio, workers): + +1. Make processes **daemons** (`p.daemon = True`) so they don't block shutdown +2. Always **clean up** on exit: + ```python + queue.put('quit') + p.join(timeout=2) + if p.is_alive(): + p.terminate() + ``` +3. Use **queues** for inter-process communication (not globals) + +## Testing & Documentation + +### Integration Testing + +For features involving file I/O, configuration, or multi-component interaction, write integration tests: + +```python +def test_high_score_persistence(): + """Test that high scores are saved and loaded correctly.""" + manager = HighScoreManager() + manager.save_game(score=100, length=15, speed=7) + + # Reload from disk + manager2 = HighScoreManager() + assert manager2.high_score == 100 +``` + +**When**: Testing config loader, score persistence, sound initialization +**Why**: Ensures data survives across restarts and different processes load correctly + +**Pattern**: +1. Create temporary test data or use fixtures +2. Verify both save and load operations +3. Test error cases (missing files, corrupted JSON) +4.

Here's my analysis of your Snake CLI game with recommendations for improvement: + +## **Code Quality & Architecture** + +1. **Separation of Concerns**: Move sound/music logic into a separate module (`sound_manager.py`). The sound process function is 30+ lines that could be cleaner. + +2. **Magic Numbers**: Several hardcoded values should be constants: + - Wait time values (250, 225, 200, etc.) for snake speed + - Screen padding calculations (e.g., `screen_width - 5`, `screen_width - 2`) + - Define these at the class level for maintainability + +3. **Color Management**: Create a dedicated colors/theme class instead of storing color pairs in a dict + +4. **Type Hints**: Add more comprehensive type hints throughout. The `ask_question` method has `Any` which could be more specific. + +## **Bugs & Issues** + +1. **Infinite Recursion in `ask_question`**: When validation fails, it calls itself recursively, which could cause a stack overflow for repeated bad inputs. Use a loop instead. + +2. **File Path Issues**: Sound/music files use relative paths (`'effects/bing.mp3'`), which breaks if the game runs from a different directory. Use `pathlib.Path(__file__).parent` to make them absolute. + +3. **Error Handling**: No error handling if sound files are missing. Should gracefully degrade if a file doesn't exist. + +4. **Curses State Management**: The cursor visibility and echo/cbreak modes could leave the terminal in a bad state if the game crashes. Use try/finally blocks or curses.wrapper more thoroughly. + +5. **Semicolons**: Line 415 has `pygame.mixer.music.pause();` - remove unnecessary semicolon (Python style) + +6. **Input Validation Bug**: In `ask_question`, when validation fails and it calls itself recursively, it doesn't pass `value_min` and `value_max` correctly (swapped parameters). + +## **Features & UX** + +1. **High Score Tracking**: Add persistent high score storage (JSON file in home directory) + +2. **Game Statistics**: Track games played, average score, best score this session + +3. **Difficulty Presets**: Instead of manual speed input, offer Easy/Medium/Hard/Custom presets + +4. **Keyboard Shortcuts Menu**: Show available keys at game start (ESC for pause, R for restart, etc.) + +5. **Terminal Resize Handling**: Game doesn't handle terminal resize during gameplay - could cause crashes or rendering issues + +6. **Better Pause Menu**: Show current score and game duration in pause menu + +7. **Configurable Character Set**: Save preferred characters/colors to a config file + +## **Performance & Cleanup** + +1. **Process Cleanup**: Process `p` is started but never explicitly joined/terminated. This could leave zombie processes. + +2. **Queue Message Format**: Use a message class or typed dict instead of plain strings for queue messages (makes it more maintainable) + +3. **Sleep in Sound Loop**: The 0.1s sleep in sound_process could be event-based (though this is minor) + +## **Testing & Documentation** + +1. **Add a README**: Document how to run, configure music/effects, requirements + +2. **Settings/Config File**: Allow users to configure default speed, music choice, color scheme in a config file + +3. **Command-line Arguments**: Add argparse for `--no-music`, `--no-effects`, `--speed=5` etc. + +Would you like me to implement any of these improvements?

High Score Manager (high_score.py)** + - `GameRecord` now includes `player_name` field + - `save_game()` now takes `player_name` as the first parameter + - Added `get_player_stats(player_name)` - get stats for a specific player + - Added `get_all_stats()` - get stats for all players + - Added `get_leaderboard(limit)` - get top scores across all players + +**2. Game (snake.py)** + - Added `player_name` attribute to Game class + - At startup, asks "Enter your name: " with default "Player" + - Shows player's personal high score and game count + - During gameplay, displays player name in the score bar: `{name} | Length: {score} @ {speed}MPH {elapsed}s` + - At game over, shows: `{name} - GAME OVER! SCORE: {score} (Time: {elapsed}s)` + - Saves scores with player name to `~/.snake_scores.json` + +**Example Score File Structure:** +```json +{ + "records": [ + { + "player_name": "Alice", + "score": 45, + "length": 20, + "speed": 7, + "timestamp": "2026-04-12T10:30:45.123456" + }, + { + "player_name": "Bob", + "score": 38, + "length": 15, + "speed": 5, + "timestamp": "2026-04-12T10:31:20.654321" + } + ] +} +``` + +Now each player has their own high score tracking, and you can build leaderboards using the new `get_leaderboard()` method! + +Made changes. + +User: With the music on, when I press ESC and Restart the game, the Music turns off. It should remember the last state + +GitHub Copilot: I’m going to inspect the current pause/restart music flow and patch it so restart preserves whatever music state was last selected. + +Read [](file:///home/mreschke/Code/mreschke/python/snake/snake.py#1-1), lines 1 to 320 + +Read [](file:///home/mreschke/Code/mreschke/python/snake/snake.py#320-320), lines 320 to 520 + +I found the root cause: in the pause menu, `Restart` jumps straight into a new game without restoring music state. I’m adding a small helper to consistently apply music state for resume/restart/toggle paths. + +Generating patch (55 lines) in [](file:///home/mreschke/Code/mreschke/python/snake/snake.py) + + +``` + +``` + + +Checked [](file:///home/mreschke/Code/mreschke/python/snake/snake.py), no problems found + +Fixed. Restart from the ESC pause menu now preserves the current music setting. + +What changed in snake.py: +- Added a new helper: `_apply_music_state(paused: bool = False)` to centralize music behavior. +- Pause menu now uses this helper for: + - entering pause (`paused=True`) + - resume (`paused=False`) + - restart (`paused=False`) before starting a new game + - toggling music while paused (`paused=True`) +- This also handles the case where music was toggled ON while paused but had never started yet. + +Result: +- If music is ON, ESC -> Restart keeps music on. +- If music is OFF, ESC -> Restart keeps music off. +- Music toggle in pause menu is now applied consistently. + +Made changes. + +User: Can you save the entire chat above to a CHAT.md file so I can read it later? + +GitHub Copilot: I’ll create a conversation log file in your project root and include the full visible transcript from this chat so you can revisit it later. + +Searched for files matching `**/CHAT.md`, no matches + +Created [](file:///home/mreschke/Code/mreschke/python/snake/CHAT.md) + +Saved. I created CHAT.md in your project root with the full visible conversation transcript from this session so far. + +If you want, I can also append command and file-change metadata (for example edited files and timestamps) as a second section. + +Made changes. + +User: Yes please + +GitHub Copilot: I’ll append a second section to CHAT.md with useful metadata (edited files and git change state) so the log is easier to audit later. + +Read changed files in [](file:///home/mreschke/Code/mreschke/python/snake) + +Read [](file:///home/mreschke/Code/mreschke/python/snake/CHAT.md) + +I’ve gathered the current repo state; next I’ll append a metadata section to CHAT.md with timestamp and current changed files so your log includes both chat and context. + +Generating patch (28 lines) in [](file:///home/mreschke/Code/mreschke/python/snake/CHAT.md) + + +``` + +``` +Done.

What is the difference? + +GitHub Copilot: Great question. They serve different purposes: + +- constants.py: developer-owned defaults and fixed rules in code. +- `~/.snake_config.json`: user-owned preferences that can change between runs without editing code. + +Practical split: + +- Use constants.py for things like min/max limits, speed map, required screen size, color IDs, and safe default values. +- Use `~/.snake_config.json` for per-user choices like preferred snake length/speed, music/effects on/off, and character style. + +Why both is useful: + +1. Constants keep the game logic stable and version-controlled. +2. Config lets each player keep their own settings persistently. +3. You can update code defaults later without clobbering a user’s existing preferences. + +A good mental model: +- constants.py = “what the game is allowed to do.” +- `~/.snake_config.json` = “how this user wants it configured today.” diff --git a/README.md b/README.md new file mode 100644 index 0000000..87952e6 --- /dev/null +++ b/README.md @@ -0,0 +1,233 @@ +# Snake CLI Game + +A modern, feature-rich Snake game for the terminal using Python's curses library. + +## Features + +- **Classic Snake Gameplay**: Navigate the snake, eat food, and avoid collisions +- **Configurable Difficulty**: Adjust snake speed (1-10) and starting length (1+) +- **Sound Effects & Music**: Optional background music and sound effects for game events +- **High Score Tracking**: Persistent high scores stored in your home directory +- **Game Statistics**: Track total games played, average score, and best score +- **Pause Menu**: Press ESC to pause with game timer and quick menu access +- **Responsive Controls**: Arrow keys for direction, quick restart capability +- **Terminal-Friendly**: Works in any terminal with proper escape sequence support + +## Installation + +### Requirements +- Python 3.12+ +- Pygame (for sound/music) + +### Setup + +1.
