2025 - -**Purpose**: Document caching strategies and implementation patterns for performance optimization - ---- - -## Overview - -RiceCoder uses a file-based cache manager (`ricecoder_storage::CacheManager`) to cache expensive computations and I/O operations. This document describes caching strategies and implementation patterns. - ---- - -## Cache Manager API - -The `CacheManager` provides a simple key-value cache with TTL and manual invalidation support. - -### Basic Usage - -```rust -use ricecoder_storage::{CacheManager, CacheInvalidationStrategy}; - -// Create cache manager -let cache = CacheManager::new("/path/to/cache")?; - -// Set a cached value with TTL (3600 seconds = 1 hour) -cache.set( - "config_key", - config_json, - CacheInvalidationStrategy::Ttl(3600), -)?; - -// Get a cached value -if let Some(cached_config) = cache.get("config_key")? { - // Use cached value -} else { - // Compute and cache -} - -// Invalidate a cached value -cache.invalidate("config_key")?; - -// Check if key exists and is not expired -if cache.exists("config_key")? { - // Use cached value -} - -// Clear all cache -cache.clear()?; - -// Clean up expired entries -let cleaned = cache.cleanup_expired()?; -``` - ---- - -## Caching Strategies - -### 1. Configuration Caching - -**What**: Cache parsed configuration files - -**Why**: Configuration parsing is expensive (YAML/JSON parsing, validation) - -**TTL**: 3600 seconds (1 hour) - reload on file change or after 1 hour - -**Implementation**: - -```rust -use ricecoder_storage::{CacheManager, CacheInvalidationStrategy}; -use std::path::Path; - -pub struct ConfigCache { - cache: CacheManager, -} - -impl ConfigCache { - pub fn new(cache_dir: &Path) -> Result { - Ok(Self { - cache: CacheManager::new(cache_dir)?, - }) - } - - pub fn get_config(&self, config_path: &Path) -> Result { - let cache_key = format!("config_{}", config_path.display()); - - // Check cache first - if let Some(cached) = self.cache.get(&cache_key)? { - return Ok(serde_json::from_str(&cached)?); - } - - // Load and parse config - let content = std::fs::read_to_string(config_path)?; - let config: Config = serde_yaml::from_str(&content)?; - - // Cache for 1 hour - let json = serde_json::to_string(&config)?; - self.cache.set( - &cache_key, - json, - CacheInvalidationStrategy::Ttl(3600), - )?; - - Ok(config) - } - - pub fn invalidate_config(&self, config_path: &Path) -> Result<()> { - let cache_key = format!("config_{}", config_path.display()); - self.cache.invalidate(&cache_key)?; - Ok(()) - } -} -``` - -### 2. Provider Response Caching - -**What**: Cache AI provider responses - -**Why**: Avoid redundant API calls for same prompts - -**TTL**: 86400 seconds (24 hours) - responses are stable - -**Implementation**: - -```rust -use ricecoder_storage::{CacheManager, CacheInvalidationStrategy}; -use sha2::{Sha256, Digest}; - -pub struct ProviderCache { - cache: CacheManager, -} - -impl ProviderCache { - pub fn new(cache_dir: &Path) -> Result { - Ok(Self { - cache: CacheManager::new(cache_dir)?, - }) - } - - pub async fn get_response( - &self, - provider: &str, - model: &str, - prompt: &str, - ) -> Result> { - let cache_key = self.make_cache_key(provider, model, prompt); - - // Check cache first - if let Some(cached) = self.cache.get(&cache_key)? { - tracing::debug!("Cache hit for provider response"); - return Ok(Some(cached)); - } - - Ok(None) - } - - pub fn cache_response( - &self, - provider: &str, - model: &str, - prompt: &str, - response: &str, - ) -> Result<()> { - let cache_key = self.make_cache_key(provider, model, prompt); - - // Cache for 24 hours - self.cache.set( - &cache_key, - response.to_string(), - CacheInvalidationStrategy::Ttl(86400), - )?; - - Ok(()) - } - - fn make_cache_key(&self, provider: &str, model: &str, prompt: &str) -> String { - // Use hash of prompt to avoid long keys - let mut hasher = Sha256::new(); - hasher.update(prompt.as_bytes()); - let hash = format!("{:x}", hasher.finalize()); - - format!("provider_{}_{}_{}",provider, model, hash) - } -} -``` - -### 3. Spec Parsing Caching - -**What**: Cache parsed specification files - -**Why**: Spec parsing is expensive (YAML parsing, validation, context building) - -**TTL**: 3600 seconds (1 hour) - reload on file change - -**Implementation**: - -```rust -use ricecoder_storage::{CacheManager, CacheInvalidationStrategy}; - -pub struct SpecCache { - cache: CacheManager, -} - -impl SpecCache { - pub fn new(cache_dir: &Path) -> Result { - Ok(Self { - cache: CacheManager::new(cache_dir)?, - }) - } - - pub fn get_spec(&self, spec_path: &Path) -> Result { - let cache_key = format!("spec_{}", spec_path.display()); - - // Check cache first - if let Some(cached) = self.cache.get(&cache_key)? { - return Ok(serde_json::from_str(&cached)?); - } - - // Parse spec - let spec = parse_spec_file(spec_path)?; - - // Cache for 1 hour - let json = serde_json::to_string(&spec)?; - self.cache.set( - &cache_key, - json, - CacheInvalidationStrategy::Ttl(3600), - )?; - - Ok(spec) - } - - pub fn invalidate_spec(&self, spec_path: &Path) -> Result<()> { - let cache_key = format!("spec_{}", spec_path.display()); - self.cache.invalidate(&cache_key)?; - Ok(()) - } -} -``` - -### 4. Project Analysis Caching - -**What**: Cache project structure analysis results - -**Why**: Project analysis is expensive (file tree traversal, dependency parsing) - -**TTL**: 3600 seconds (1 hour) - reload on file change - -**Implementation**: - -```rust -use ricecoder_storage::{CacheManager, CacheInvalidationStrategy}; - -pub struct ProjectAnalysisCache { - cache: CacheManager, -} - -impl ProjectAnalysisCache { - pub fn new(cache_dir: &Path) -> Result { - Ok(Self { - cache: CacheManager::new(cache_dir)?, - }) - } - - pub fn get_analysis(&self, project_path: &Path) -> Result> { - let cache_key = format!("analysis_{}", project_path.display()); - - if let Some(cached) = self.cache.get(&cache_key)? { - return Ok(Some(serde_json::from_str(&cached)?)); - } - - Ok(None) - } - - pub fn cache_analysis( - &self, - project_path: &Path, - analysis: &ProjectAnalysis, - ) -> Result<()> { - let cache_key = format!("analysis_{}", project_path.display()); - - // Cache for 1 hour - let json = serde_json::to_string(analysis)?; - self.cache.set( - &cache_key, - json, - CacheInvalidationStrategy::Ttl(3600), - )?; - - Ok(()) - } - - pub fn invalidate_analysis(&self, project_path: &Path) -> Result<()> { - let cache_key = format!("analysis_{}", project_path.display()); - self.cache.invalidate(&cache_key)?; - Ok(()) - } -} -``` - ---- - -## Cache Statistics and Monitoring - -### Cache Hit Rate Tracking - -```rust -use std::sync::atomic::{AtomicU64, Ordering}; -use std::sync::Arc; - -pub struct CacheStats { - hits: Arc, - misses: Arc, -} - -impl CacheStats { - pub fn new() -> Self { - Self { - hits: Arc::new(AtomicU64::new(0)), - misses: Arc::new(AtomicU64::new(0)), - } - } - - pub fn record_hit(&self) { - self.hits.fetch_add(1, Ordering::Relaxed); - } - - pub fn record_miss(&self) { - self.misses.fetch_add(1, Ordering::Relaxed); - } - - pub fn hit_rate(&self) -> f64 { - let hits = self.hits.load(Ordering::Relaxed); - let misses = self.misses.load(Ordering::Relaxed); - let total = hits + misses; - - if total == 0 { - 0.0 - } else { - hits as f64 / total as f64 - } - } - - pub fn stats(&self) -> (u64, u64, f64) { - let hits = self.hits.load(Ordering::Relaxed); - let misses = self.misses.load(Ordering::Relaxed); - let rate = self.hit_rate(); - (hits, misses, rate) - } -} -``` - -### Logging Cache Operations - -```rust -use tracing::{debug, info}; - -pub fn log_cache_stats(stats: &CacheStats) { - let (hits, misses, rate) = stats.stats(); - info!( - "Cache statistics: {} hits, {} misses, {:.2}% hit rate", - hits, - misses, - rate * 100.0 - ); -} -``` - ---- - -## Cache Invalidation Strategies - -### 1. Time-Based (TTL) - -**When**: Data changes infrequently (configs, specs, analysis) - -**TTL Values**: -- Configuration: 3600 seconds (1 hour) -- Specs: 3600 seconds (1 hour) -- Project analysis: 3600 seconds (1 hour) -- Provider responses: 86400 seconds (24 hours) - -**Pros**: Automatic cleanup, simple to implement - -**Cons**: Stale data possible, requires TTL tuning - -### 2. Manual Invalidation - -**When**: Data changes on demand (user edits, file changes) - -**Implementation**: - -```rust -// Invalidate on file change -pub fn on_file_changed(&self, path: &Path) { - let cache_key = format!("spec_{}", path.display()); - let _ = self.cache.invalidate(&cache_key); -} - -// Invalidate on user action -pub fn on_config_updated(&self) { - let _ = self.cache.invalidate("config_global"); - let _ = self.cache.invalidate("config_project"); -} -``` - -**Pros**: Always fresh data, no stale data - -**Cons**: Requires explicit invalidation, more complex - -### 3. Hybrid Approach - -**When**: Combine TTL and manual invalidation - -**Implementation**: - -```rust -pub struct HybridCache { - cache: CacheManager, -} - -impl HybridCache { - pub fn get_with_invalidation( - &self, - key: &str, - file_path: &Path, - ) -> Result> { - // Check if file was modified since cache creation - let metadata = std::fs::metadata(file_path)?; - let modified = metadata.modified()?; - - // If file was modified, invalidate cache - if let Ok(cached) = self.cache.get(key) { - if cached.is_some() { - // Check file modification time - // If newer than cache, invalidate - let _ = self.cache.invalidate(key); - return Ok(None); - } - } - - self.cache.get(key) - } -} -``` - ---- - -## Cache Cleanup - -### Periodic Cleanup - -```rust -use tokio::time::{interval, Duration}; - -pub async fn start_cache_cleanup(cache: Arc) { - let mut interval = interval(Duration::from_secs(3600)); // Every hour - - loop { - interval.tick().await; - - match cache.cleanup_expired() { - Ok(cleaned) => { - tracing::info!("Cleaned up {} expired cache entries", cleaned); - } - Err(e) => { - tracing::warn!("Failed to cleanup cache: {}", e); - } - } - } -} -``` - -### Manual Cleanup - -```rust -// Clear all cache -cache.clear()?; - -// Clean up only expired entries -let cleaned = cache.cleanup_expired()?; -``` - ---- - -## Performance Impact - -### Expected Improvements - -| Operation | Before | After | Improvement | -|-----------|--------|-------|-------------| -| Config loading | 500ms | 50ms | 10x | -| Spec parsing | 1000ms | 100ms | 10x | -| Project analysis | 2000ms | 200ms | 10x | -| Provider response | 5000ms | 50ms | 100x | - -### Cache Size Estimates - -| Cache Type | Typical Size | Max Size | -|-----------|--------------|----------| -| Configuration | 10KB | 100KB | -| Specs | 50KB | 500KB | -| Project analysis | 100KB | 1MB | -| Provider responses | 500KB | 5MB | - ---- - -## Best Practices - -1. **Use appropriate TTLs**: Balance freshness vs. performance -2. **Monitor cache hit rates**: Adjust TTLs based on actual usage -3. **Clean up expired entries**: Run periodic cleanup to save disk space -4. **Invalidate on changes**: Manually invalidate when data changes -5. **Log cache operations**: Track cache performance for optimization -6. **Test cache behavior**: Ensure correctness with caching enabled - ---- - -## Testing Cache Behavior - -### Unit Tests - -```rust -#[test] -fn test_cache_hit_rate() -> Result<()> { - let cache = CacheManager::new(temp_dir.path())?; - let stats = CacheStats::new(); - - // Populate cache - cache.set("key1", "data1".to_string(), CacheInvalidationStrategy::Manual)?; - - // First access: miss - if cache.get("key1")?.is_none() { - stats.record_miss();

Lazy Initialization - -Defer expensive initialization until needed. - -**Example**: Providers - -```rust -// Before: Initialize all providers on startup -let providers = vec![ - OpenAiProvider::new()?, - AnthropicProvider::new()?, - OllamaProvider::new()?, -]; - -// After: Initialize only when needed -let provider = match provider_name { - "openai" => OpenAiProvider::new()?, - "anthropic" => AnthropicProvider::new()?, - "ollama" => OllamaProvider::new()?, - _ => return Err("Unknown provider"), -}; -``` - -### 2. Caching - -Cache expensive computations. - -**Example**: Configuration - -```rust -// Before: Parse config every time -fn get_config() -> Result { - let yaml = std::fs::read_to_string("config.yaml")?; - serde_yaml::from_str(&yaml) -} - -// After: Cache parsed config -lazy_static::lazy_static! { - static ref CONFIG_CACHE: Mutex> = Mutex::new(None); -} - -fn get_config() -> Result { - let mut cache = CONFIG_CACHE.lock().unwrap(); - if let Some(config) = cache.as_ref() { - return Ok(config.clone()); - } - - let yaml = std::fs::read_to_string("config.yaml")?; - let config = serde_yaml::from_str(&yaml)?; - *cache = Some(config.clone()); - Ok(config) -} -``` - -### 3. Async I/O - -Use async operations for I/O-bound tasks. - -**Example**: File reading - -```rust -// Before: Blocking I/O -fn read_file(path: &str) -> Result { - std::fs::read_to_string(path) -} - -// After: Async I/O -async fn read_file(path: &str) -> Result { - tokio::fs::read_to_string(path).await -} -``` - -### 4.

This design allows adding support for new languages through configuration files without modifying code. - -## Architecture Principles - -### 1. Language-Agnostic Core - -The core LSP server is language-agnostic and delegates language-specific behavior to pluggable providers: - -- **Semantic Analysis**: `SemanticAnalyzerProvider` trait for language-specific parsing and symbol extraction -- **Diagnostics**: `DiagnosticsProvider` trait for language-specific diagnostic rules -- **Code Actions**: `CodeActionProvider` trait for language-specific transformations - -### 2. Configuration-Driven Behavior - -Language-specific behavior is defined in configuration files (YAML/JSON) rather than hardcoded: - -- **Language Configuration**: Defines parser plugins, diagnostic rules, and code actions -- **Diagnostic Rules**: Pattern-based rules for generating diagnostics -- **Code Action Templates**: Transformation templates for fixing issues - -### 3. Graceful Degradation - -The system provides basic functionality for unconfigured languages: - -- **Fallback Analysis**: Generic text-based analysis for unknown languages -- **Empty Diagnostics**: No diagnostics for unconfigured languages -- **No Errors**: System continues functioning without crashing - -### 4. Hot-Reload Support - -Configurations can be reloaded at runtime without restarting the LSP server: - -- **Configuration Registry**: Manages language configurations -- **Provider Registries**: Manage semantic, diagnostics, and code action providers -- **Runtime Updates**: Configurations can be updated without server restart - -## Architecture Diagram - -``` -ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā” -ā”‚ LSP Client (IDE) ā”‚ -ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”¬ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜ - ā”‚ LSP Protocol (JSON-RPC) - ā”‚ -ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā–¼ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā” -ā”‚ Configuration Manager ā”‚ -ā”‚ - Load language configurations from files ā”‚ -ā”‚ - Manage provider registries ā”‚ -ā”‚ - Support hot-reload of configurations ā”‚ -ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”¬ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜ - ā”‚ -ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā–¼ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā” -ā”‚ LSP Server (Language-Agnostic) ā”‚ -ā”‚ ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā” ā”‚ -ā”‚ ā”‚ LSP Protocol Handler ā”‚ ā”‚ -ā”‚ ā”‚ - Initialize/Shutdown ā”‚ ā”‚ -ā”‚ ā”‚ - Document Synchronization ā”‚ ā”‚ -ā”‚ ā”‚ - Request Routing ā”‚ ā”‚ -ā”‚ ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜ ā”‚ -ā”‚ ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā” ā”‚ -ā”‚ ā”‚ Generic Semantic Analyzer (with Providers) ā”‚ ā”‚ -ā”‚ ā”‚ - Delegates to language-specific providers ā”‚ ā”‚ -ā”‚ ā”‚ - Falls back to generic analysis ā”‚ ā”‚ -ā”‚ ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜ ā”‚ -ā”‚ ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā” ā”‚ -ā”‚ ā”‚ Generic Diagnostics Engine (with Providers) ā”‚ ā”‚ -ā”‚ ā”‚ - Applies configured diagnostic rules ā”‚ ā”‚ -ā”‚ ā”‚ - Falls back to empty diagnostics ā”‚ ā”‚ -ā”‚ ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜ ā”‚ -ā”‚ ā”Œā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā” ā”‚ -ā”‚ ā”‚ Generic Code Actions Engine (with Providers) ā”‚ ā”‚ -ā”‚ ā”‚ - Applies configured transformations ā”‚ ā”‚ -ā”‚ ā”‚ - Falls back to no actions ā”‚ ā”‚ -ā”‚ ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜ ā”‚ -ā””ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”€ā”˜ -``` - -## Key Components - -### Configuration Registry - -Manages language configurations loaded from files: - -```rust -pub struct ConfigRegistry { - languages: HashMap, -} - -impl ConfigRegistry { - pub fn register(&mut self, config: LanguageConfig) -> ConfigResult<()>;
