Separate utilities and commands into dedicated modules
Extract functionality from handlers.py into focused modules: New Modules: - bot/message_utils.py (120 lines) - Telegram message handling * send_or_edit_with_image() - Smart message/image transitions * Image caching and upload logic - bot/commands.py (110 lines) - Slash command handlers * start() - Player initialization * export_map() - Admin map export * spawn_stats() - Admin spawn statistics Refactored: - bot/handlers.py: 365 → 177 lines (-51% reduction) * Now contains only routing logic * Re-exports commands for backward compatibility * Cleaner, more focused responsibility Benefits: - Single Responsibility Principle achieved - Better testability (can test modules independently) - Improved organization and discoverability - Easier maintenance (changes isolated to specific files) - Full backward compatibility maintained Documented in MODULE_SEPARATION.md

||||
**Status:** ✅ Complete
|
||||
|
||||
## Overview
|
||||
|
||||
Extracted utility functions and command handlers from `handlers.py` into separate, focused modules, achieving true single-responsibility principle.
|
||||
|
||||
## Changes
|
||||
|
||||
### New Modules Created
|
||||
|
||||
#### 1. `bot/message_utils.py` (120 lines)
|
||||
**Purpose:** Message sending and editing utilities
|
||||
|
||||
**Contains:**
|
||||
- `send_or_edit_with_image()` - Smart message/image handling
|
||||
- Image caching and upload
|
||||
- Smooth transitions between images
|
||||
- Text-only message handling
|
||||
- Edit vs send logic
|
||||
|
||||
**Responsibilities:**
|
||||
- Telegram message manipulation
|
||||
- Image file I/O and caching
|
||||
- Error handling for message edits
|
||||
|
||||
#### 2. `bot/commands.py` (110 lines)
|
||||
**Purpose:** Slash command handlers
|
||||
|
||||
**Contains:**
|
||||
- `start()` - Initialize player and show status
|
||||
- `export_map()` - Export map data as JSON (admin only)
|
||||
- `spawn_stats()` - Show enemy spawn statistics (admin only)
|
||||
|
||||
**Responsibilities:**
|
||||
- Command implementation
|
||||
- Player initialization
|
||||
- Admin commands
|
||||
|
||||
### Refactored Module
|
||||
|
||||
#### `bot/handlers.py`
|
||||
**Before:** 365 lines (routing + utilities + commands)
|
||||
**After:** 177 lines (pure routing only)
|
||||
**Reduction:** -188 lines (-51%)
|
||||
|
||||
**Now Contains Only:**
|
||||
- Handler imports
|
||||
- `HANDLER_MAP` registry
|
||||
- `button_handler()` router
|
||||
- Re-exports of commands for main.py
|
||||
|
||||
**Removed:**
|
||||
- ~~120 lines of utility functions~~
|
||||
- ~~110 lines of command handlers~~
|
||||
|
||||
## Architecture
|
||||
|
||||
### Before
|
||||
```
|
||||
handlers.py (365 lines)
|
||||
├── Imports (60 lines)
|
||||
├── Handler Registry (50 lines)
|
||||
├── Utility Functions (120 lines) ❌ Mixed concerns
|
||||
├── Command Handlers (110 lines) ❌ Mixed concerns
|
||||
└── Button Router (25 lines)
|
||||
```
|
||||
|
||||
### After
|
||||
```
|
||||
handlers.py (177 lines) - Pure routing
|
||||
├── Imports
|
||||
├── Handler Registry
|
||||
└── Button Router
|
||||
|
||||
message_utils.py (120 lines) - Message handling
|
||||
└── send_or_edit_with_image()
|
||||
|
||||
commands.py (110 lines) - Command handlers
|
||||
├── start()
|
||||
├── export_map()
|
||||
└── spawn_stats()
|
||||
```
|
||||
|
||||
## Benefits
|
||||
|
||||
### 1. **Single Responsibility Principle**
|
||||
Each module has one clear purpose:
|
||||
- `handlers.py` → Route button callbacks
|
||||
- `message_utils.py` → Handle Telegram messages
|
||||
- `commands.py` → Implement slash commands
|
||||
|
||||
### 2. **Improved Testability**
|
||||
Can test each module independently:
|
||||
```python
|
||||
# Test message utils without routing
|
||||
from bot.message_utils import send_or_edit_with_image
|
||||
|
||||
# Test commands without button handlers
|
||||
from bot.commands import start, export_map
|
||||
|
||||
# Test routing without utility logic
|
||||
from bot.handlers import button_handler
|
||||
```
|
||||
|
||||
### 3. **Better Organization**
|
||||
Clear separation of concerns:
|
||||
- **Routing logic** → handlers.py
|
||||
- **Message I/O** → message_utils.py
|
||||
- **User commands** → commands.py
|
||||
- **Game actions** → action_handlers.py, combat_handlers.py, etc.
|
||||
|
||||
### 4. **Easier Maintenance**
|
||||
- Find code faster (know which file to open)
|
||||
- Modify one concern without affecting others
|
||||
- Less merge conflicts (changes in different files)
|
||||
|
||||
### 5. **Cleaner Imports**
|
||||
```python
|
||||
# Before (everything from handlers)
|
||||
from bot.handlers import start, button_handler, send_or_edit_with_image
|
||||
|
||||
# After (clear module boundaries)
|
||||
from bot.handlers import button_handler
|
||||
from bot.commands import start
|
||||
from bot.message_utils import send_or_edit_with_image
|
||||
```
|
||||
|
||||
## File Structure
|
||||
|
||||
```
|
||||
bot/
|
||||
├── __init__.py
|
||||
├── handlers.py (177 lines) - Router only
|
||||
├── message_utils.py (120 lines) - Message utilities
|
||||
├── commands.py (110 lines) - Slash commands
|
||||
├── action_handlers.py (372 lines) - World actions
|
||||
├── inventory_handlers.py(355 lines) - Inventory
|
||||
├── combat_handlers.py (172 lines) - Combat
|
||||
├── profile_handlers.py (147 lines) - Stats
|
||||
├── corpse_handlers.py (234 lines) - Looting

||||
## Code Metrics
|
||||
|
||||
| Metric | Before | After | Change |
|
||||
|--------|--------|-------|--------|
|
||||
| handlers.py size | 365 lines | 177 lines | -188 (-51%) |
|
||||
| Modules | 10 | 12 | +2 |
|
||||
| Max module size | 372 lines | 372 lines | Unchanged |
|
||||
| Avg module size | ~250 lines | ~200 lines | -50 lines |
|
||||
| Separation of Concerns | ⚠️ Mixed | ✅ Clean | Improved |
|
||||
|
||||
## Backward Compatibility
|
||||
|
||||
✅ **Fully backward compatible**
|
||||
|
||||
The refactoring maintains all existing interfaces:
|
||||
```python
|
||||
# main.py continues to work unchanged
|
||||
from bot import handlers
|
||||
|
||||
application.add_handler(CommandHandler("start", handlers.start))
|
||||
application.add_handler(CallbackQueryHandler(handlers.button_handler))
|
||||
```
|
||||
|
||||
`handlers.py` re-exports commands for compatibility:
|
||||
```python
|
||||
# handlers.py
|
||||
from .commands import start, export_map, spawn_stats # Re-export
|
||||
|
||||
# Allows: handlers.start (from main.py)
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
All modules tested and working:
|
||||
- ✅ `bot/handlers.py` - Router works correctly
|
||||
- ✅ `bot/message_utils.py` - Image handling works
|
||||
- ✅ `bot/commands.py` - Commands execute properly
|
||||
- ✅ No import errors
|
||||
- ✅ No runtime errors
|
||||
- ✅ All handler calls work identically
|
||||
|
||||
## Migration Path
|
||||
|
||||
If you want to update imports in the future:
|
||||
|
||||
### Option 1: Keep Current (Recommended)
|
||||
```python
|
||||
# main.py
|
||||
from bot import handlers
|
||||
handlers.start # Works via re-export
|
||||
```
|
||||
|
||||
### Option 2: Direct Imports
|
||||
```python
|
||||
# main.py
|
||||
from bot.commands import start, export_map, spawn_stats
|
||||
from bot.handlers import button_handler
|
||||
```
|
||||
|
||||
Both work identically!
|
||||
|
||||
## Conclusion
|
||||
|
||||
This refactoring achieves:
|
||||
- ✅ **51% reduction** in handlers.py size
|
||||
- ✅ **Clear separation** of concerns
|
||||
- ✅ **Better organization** and discoverability
|
||||
- ✅ **Improved testability** and maintainability
|
||||
- ✅ **Full backward compatibility**
|
||||
- ✅ **No behavior changes**
|
||||
|
||||
The codebase is now cleaner, more modular, and follows best practices for Python project structure!
