# Specialized Language Plugins Architecture
## Overview
This document outlines the architecture for specialized language plugins that provide advanced features beyond basic tree-sitter AST parsing. These plugins offer cross-file analysis, type system understanding, and build tool integration.
## Core Architecture Principles
### 1. Inheritance Model
All specialized plugins inherit from `GenericTreeSitterPlugin` to leverage:
- Basic tree-sitter parsing
- Query caching
- Symbol extraction
- Semantic search base functionality
```python
class SpecializedLanguagePlugin(GenericTreeSitterPlugin):
"""Base class for all specialized plugins"""
def __init__(self, sqlite_store=None, enable_semantic=True):
super().__init__(language_config, sqlite_store, enable_semantic)
self.import_resolver = self._create_import_resolver()
self.type_analyzer = self._create_type_analyzer()
self.build_system = self._create_build_system()
```
### 2. Component Architecture
#### Core Components per Plugin:
1. **Import Resolver**: Handles module/package imports and dependencies
2. **Type Analyzer**: Understands type systems, generics, interfaces
3. **Build System Integration**: Interfaces with language-specific build tools
4. **Cross-File Analyzer**: Tracks references and dependencies across files
5. **Framework Support**: Optional framework-specific intelligence
### 3. Enhanced Capabilities
Each specialized plugin provides:
- **Advanced Symbol Definition**: Including type information, visibility, modifiers
- **Reference Resolution**: Find all usages across the codebase
- **Import Graph**: Dependency tracking and circular dependency detection
- **Type Inference**: Understand implicit types and generics
- **Build Context**: Resolve external dependencies from build files
- **Contextual Embeddings**: Language-specific context for better semantic search
- Type-aware embeddings that understand generics, interfaces, traits
- Import-context embeddings that capture dependency relationships
- Framework-aware embeddings (e.g., React hooks, Spring annotations)
- Cross-file relationship embeddings for better code navigation

## Common Patterns
### 1. Lazy Loading Pattern
```python
class SpecializedPlugin:
def __init__(self):
self._analyzer = None
@property
def analyzer(self):
if self._analyzer is None:
self._analyzer = self._create_analyzer()
return self._analyzer
```
### 2. Cache Strategy
```python
class CrossFileCache:
def __init__(self):
self._import_graph = {}
self._type_cache = {}
self._reference_cache = {}
def invalidate_file(self, file_path):
# Invalidate all caches for changed file
pass
```
### 3. Incremental Analysis
```python
class IncrementalAnalyzer:
def analyze_file(self, file_path, content):
# Only analyze changed portions
old_ast = self.cache.get_ast(file_path)
new_ast = self.parse(content)
diff = self.compute_diff(old_ast, new_ast)
self.apply_incremental_changes(diff)
```
### 4. Contextual Embeddings Pattern
```python
class ContextualEmbeddingEnhancer:
"""Enhances specialized plugins with contextual embeddings"""
def __init__(self):
self._context_cache = {}
self._relationship_graph = {}
def generate_contextual_embedding(self, symbol, plugin_context):
"""Generate embeddings that understand language-specific context"""
# Combine symbol info with:
# - Type information from specialized plugin
# - Import/dependency context
# - Framework-specific patterns
# - Cross-file relationships
context = {
'symbol': symbol,
'type_info': plugin_context.type_analyzer.get_type(symbol),
'imports': plugin_context.import_resolver.get_dependencies(),
'references': plugin_context.get_references(symbol),
'framework': plugin_context.detect_framework_patterns()
}
return self.embed_with_context(context)
```
## Integration Points
### 1. With Existing System
- Maintains compatibility with IPlugin interface
- Uses same SQLite storage schema
- Integrates with semantic search
- Works with file watcher
### 2. External Tool Integration
```python
class ExternalToolBridge:
"""Base class for integrating external analysis tools"""
def __init__(self, tool_path):
self.tool_path = tool_path
self.process_pool = ProcessPoolExecutor()
async def analyze(self, source_code):
# Run external tool and parse results
pass
```
### 3. Language Server Protocol (LSP) Integration
```python
class LSPClient:
"""Optional LSP client for advanced features"""
def __init__(self, language_server_cmd):
self.lsp_process = None
self.capabilities = {}
async def get_references(self, file_path, position):
# Use LSP for accurate references
pass
```
## Performance Considerations
### 1. Caching Strategy
- AST caching per file
- Import graph caching
- Type resolution caching
- Cross-file reference caching
### 2. Parallel Processing
- Analyze independent files in parallel
- Batch external tool calls
- Concurrent type resolution
### 3. Memory Management
- Limit AST cache size
- Use weak references for large objects
- Periodic cache cleanup
## Testing Strategy
### 1. Unit Tests
- Test each component independently
- Mock external dependencies
- Test error handling
### 2. Integration Tests
- Test with real codebases
- Verify cross-file features
- Test build system integration
### 3. Performance Tests
- Benchmark against generic plugin
- Measure memory usage
- Test with large codebases

## Contextual Embeddings Benefits
### Language-Specific Context Understanding
Each specialized plugin enhances embeddings with:
1. **Type Context** - Embeddings understand type hierarchies, generics, and constraints
2. **Import Context** - Dependencies and module relationships inform similarity
3. **Framework Context** - Framework-specific patterns improve search relevance
4. **Cross-File Context** - Related code across files is semantically linked
### Example: Java Plugin Contextual Embeddings
```java
// When embedding this method:
public void processOrder(Order order) {
// The embedding includes:
// - Parameter type: Order (custom class)
// - Return type: void
// - Class context: OrderService
// - Imports: com.example.models.Order
// - Framework: Spring @Service annotation
// - Related methods: validateOrder, saveOrder
}
```
### Example: TypeScript Plugin Contextual Embeddings
```typescript
// When embedding this React component:
export const UserProfile: FC<UserProps> = ({ user }) => {
// The embedding includes:
// - Component type: React.FC
// - Props interface: UserProps
// - Imports: React, UserProps type
// - Framework: React functional component
// - Hooks used: useState, useEffect
// - Related components: UserAvatar, UserDetails
}
```
## Success Criteria
Each specialized plugin must:
1. Maintain <200ms response time for symbol lookup
2. Support incremental updates
3. Handle 10K+ file codebases
4. Provide accurate cross-file references
5. Integrate with build systems
6. Gracefully degrade when tools unavailable
7. Generate rich contextual embeddings for semantic search
8. Maintain <500ms for contextual embedding generation
