# System Patterns

## System Architecture
1. Configuration Layer Design
   - Core configuration (init.lua)
   - Module-based organization
   - Plugin management system
   - User customization layer

2. Feature Organization
   - LSP services management
   - Completion engine integration
   - File tree and navigation
   - Buffer and window management

3. Event System
   - Autocommands framework
   - Key mapping system
   - Plugin hooks
   - Custom events

## Key Technical Decisions
1. Plugin Management
   - Use of lazy.nvim for plugin management
   - Lazy-loading strategy for performance
   - Conditional plugin loading
   - Dependencies management

2. LSP Implementation
   - Native LSP client usage
   - Mason.nvim for LSP server management
   - Language-specific configurations
   - Diagnostic system integration

3. Performance Optimization
   - Modular loading system
   - Cache implementation
   - Startup optimization
   - Memory management

## Architecture Patterns
1. Module Pattern
   ```lua
   -- Module structure
   local M = {}
   -- Configuration
   M.setup = function(opts)
     -- Setup logic
   end
   -- Module functions
   M.function_name = function()
     -- Implementation
   end
   return M
   ```

2. Plugin Setup Pattern
   ```lua
   -- Plugin configuration pattern
   {
     "plugin/name",
     event = "Event",
     dependencies = {},
     config = function()
       require("plugin").setup({})
     end
   }
   ```

3. LSP Configuration Pattern
   ```lua
   -- LSP server setup pattern
   lspconfig[server].setup({
     capabilities = capabilities,
     on_attach = on_attach,
     settings = {}
   })
   ```

## Implementation Guidelines
1. Code Organization
   - One feature per file
   - Clear module interfaces
   - Consistent naming conventions
   - Documentation standards

2. Configuration Standards
   - User-facing options
   - Default values
   - Type checking
   - Validation

3. Error Handling
   - Graceful degradation
   - User feedback
   - Debug logging
   - Recovery mechanisms

## System Components
1. Core Components
   - Plugin manager
   - LSP client
   - Completion engine
   - File explorer

2. Language Support
   - LSP servers
   - Treesitter parsers
   - Language tools
   - Formatters

3. UI Components
   - Status line
   - Buffer line
   - Command line
   - Notifications

4. Integration Layer
   - Git integration
   - Terminal
   - Debug adapter
   - External tools
