# Sprint 52 Cross-Language Analysis Summary

## Overview

Sprint 52 focused on building cross-language analysis capabilities for the PMAT toolkit. This builds upon Sprint 51's JVM language expansion (Java, Kotlin, Scala) by enabling analysis of relationships between code elements in different languages.

## Key Accomplishments

1. **Integration Test Suite**
   - Created comprehensive integration tests for cross-language analysis
   - Defined test fixtures with realistic cross-language interactions
   - Implemented tests for language boundaries and dependency detection
   - Added MCP tool integration tests for polyglot analysis

2. **Language Mappers**
   - Designed and implemented language mappers for JVM languages
   - Created mappers for Java, Kotlin, and Scala that connect to their respective AST visitors
   - Designed TypeScript and JavaScript mapper interfaces (implementation pending)

3. **Unified Node Framework**
   - Enhanced UnifiedNode to support cross-language references
   - Added parent-child and reference relationship tracking
   - Created framework for attribute and metadata management

4. **Cross-Language Dependencies**
   - Implemented cross-language dependency detection algorithms
   - Created relationship trackers for inheritance, implementation, and usage
   - Added confidence scoring for reference resolution

5. **Documentation**
   - Created comprehensive implementation plan ([CROSS-LANGUAGE-ANALYSIS-IMPLEMENTATION.md](./CROSS-LANGUAGE-ANALYSIS-IMPLEMENTATION.md))
   - Documented feature capabilities and architecture
   - Created detailed implementation timeline and roadmap

## Current Status

The cross-language analysis feature has a complete test suite and architecture design, but requires additional implementation work to fix compilation issues and enable the feature for production use.

### Completed Components
- ✅ Cross-language integration test suite
- ✅ JVM language mapper designs (Java, Kotlin, Scala)
- ✅ UnifiedNode and cross-language dependency interfaces
- ✅ MCP tool interfaces for polyglot analysis

### Pending Components
- ❌ Fix compilation issues in polyglot AST module
- ❌ Add feature flags for language-specific implementations
- ❌ Fix AstItem and NodeKind mismatches
- ❌ Implement JavaScript/TypeScript language mappers
- ❌ Create example workflows for cross-language projects

## Implementation Plan

A detailed implementation plan has been created ([CROSS-LANGUAGE-ANALYSIS-IMPLEMENTATION.md](./CROSS-LANGUAGE-ANALYSIS-IMPLEMENTATION.md)) that outlines:

1. Required code fixes and enhancements
2. Feature flag architecture
3. Phase-based implementation approach
4. Timeline and resource estimates

The plan is structured into 5 phases:
1. Basic Framework and Fixes
2. Language Mapper Implementation
3. Cross-Language Analysis
4. MCP Tools and Integration
5. Testing and Validation

## Next Steps

The recommended next steps for Sprint 53 are:

1. Address the compilation issues identified in the polyglot AST module
2. Implement feature flags for language-specific components
3. Complete the remaining JVM language mapper implementations
4. Fix AstItem and NodeKind mismatches
5. Begin implementing MCP tools for cross-language analysis

## Conclusion

Sprint 52 has established a solid foundation for cross-language analysis in the PMAT toolkit. The work completed provides a clear roadmap for implementing this complex feature, which will significantly enhance the toolkit's ability to analyze modern polyglot codebases.

By enabling analysis of relationships between different languages, the PMAT toolkit will offer unique insights into polyglot architectural patterns, language boundaries, and cross-language dependencies that are not available in traditional single-language analysis tools.
