# System Patterns

## Architecture Patterns

### 1. Plugin System
- Uses `lazy.nvim` for plugin management.
- Plugins are defined in `init.lua`.
- Supports lazy loading via events/commands.
- Custom plugins can be added in `lua/custom/plugins/`.

### 2. Configuration Structure
```
.
├── init.lua                 # Main configuration file
├── lua/
│   ├── kickstart/          # Core functionality
│   │   └── plugins/        # Built-in plugin configs
│   └── custom/            # User customizations
│       └── plugins/       # Custom plugin configs
└── doc/                   # Documentation
```

### 3. Key Design Patterns

#### Modular Configuration
- Core settings in `init.lua`.
- Plugin-specific configurations in separate files.
- Custom configurations isolated in `lua/custom/`.

#### Event-Driven Architecture
- Uses Neovim's event system for plugin loading.
- Autocommands for specific behaviors.
- LSP events for IDE features.

#### Layer-Based Organization
1. **Core Settings Layer**
   - Basic Vim options.
   - Key mappings.
   - Global variables.

2. **Plugin Layer**
   - Plugin management.
   - Plugin configurations.
   - Plugin-specific settings.

3. **LSP Layer**
   - Language server configurations.
   - Completion setup.
   - Diagnostic settings.

4. **UI Layer**
   - Colorscheme.
   - Statusline.
   - Visual enhancements.

## Technical Decisions

### 1. Configuration Language
- Lua chosen over VimScript for:
  - Better performance.
  - Modern syntax.
  - Rich data structures.
  - Better integration with Neovim.

### 2. Plugin Selection
- Minimal but powerful set of defaults.
- Focus on maintained, actively developed plugins.
- Preference for Lua-based plugins.
- Built-in LSP over CoC or similar alternatives.

### 3. Code Organization
- Single `init.lua` for easy understanding.
- Modular structure available through `kickstart-modular.nvim`.
- Clear separation between core and user customizations.

### 4. Performance Considerations
- Lazy loading of plugins.
- Efficient event handling.
- Minimal startup impact.
- Careful LSP configuration.

## Key Technical Standards

1. **Code Style**
   - Consistent Lua formatting.
   - Clear commenting.
   - Documented configuration options.

2. **Plugin Management**
   - Versioned dependencies.
   - Conditional loading.
   - Clear plugin specifications.

3. **Error Handling**
   - Protected calls for plugin loading.
   - Fallbacks for missing dependencies.
   - Clear error messages.

4. **Documentation**
   - Inline documentation.
   - Help files.
   - Clear user instructions.
