i - **Clean Dependencies**: No circular dependencies - **OSGi Compatible**: Full bundle support with proper lifecycle management +## šŸ”„ **Cross-Language Compatibility System** + +MetaObjects includes an **automated cross-language type compatibility validation system** that ensures type definitions remain consistent across Java, C#, TypeScript, and other target languages. + +### **How It Works** + +The compatibility system runs automatically during git deployment via pre-push hooks: + +1. **Type Definition Extraction** - Scans MetaData type registrations in Java code +2. **Cross-Language Mapping** - Validates type mappings using `HelperRegistry.getLanguageType()` +3. **Compatibility Verification** - Ensures each MetaField/MetaAttribute maps correctly to: + - **Java**: Proper Java types (Integer, Long, String, etc.) + - **TypeScript**: TypeScript types (number, string, boolean, etc.) + - **C#**: C# types (int, long, string, etc.) +4. **Report Generation** - Produces compatibility report showing any mismatches + +### **Running Compatibility Checks Locally** + +**Before committing** - validate your changes don't break cross-language compatibility: + +```bash +# Run cross-language compatibility validation +cd metadata && mvn test -Dtest=CrossLanguageTypeCompatibilityTest + +# Output shows: +# āœ… Java DataTypes: 21 types +# āœ… TypeScript mappings: 9/21 compatible +# āœ… C# mappings: 9/21 compatible +# āœ… DATE serialization verified +# šŸš€ Safe to commit and deploy! +``` + +**Full test suite with compatibility checks:** + +```bash +# Run all tests including compatibility validation +cd metadata && mvn test + +# Verify entire module +cd metadata && mvn verify +``` + +### **Type Mapping Rules** + +The system validates these key compatibility rules: +- **Numeric Consolidation**: int/long/float/double ā†’ TypeScript `number` +- **String Types**: Java String ā†” TypeScript string ā†” C# string +- **Boolean Types**: Consistent across all languages +- **Date/Time**: Java Date/LocalDateTime ā†’ TypeScript Date ā†’ C# DateTime +- **Arrays**: Universal `@isArray` modifier maps to native array syntax in each language + +### **Integration with CI/CD** + +The compatibility checks are automatically triggered: +- **Pre-push hook**: Validates before code reaches remote +- **GitHub Actions**: Runs on all pull requests +- **Release pipeline**: Required check before version tagging + +### **Setting Up Git Deploy Hooks** + +To enable automatic compatibility checking on push: + +```bash +# Install the pre-push hook +cp scripts/hooks/pre-push .git/hooks/pre-push +chmod +x .git/hooks/pre-push + +# Or use Maven to install hooks +mvn metaobjects:install-hooks +``` + +The pre-push hook performs: +1. āœ… **Type Compatibility Check** - Validates Java ā†’ TypeScript/C# mappings +2. āœ… **Schema Validation** - Ensures metadata schemas are in sync +3. āœ… **API Surface Comparison** - Checks public API consistency across languages +4. āœ… **Test Execution** - Runs compatibility-specific tests + +**Hook Output Example:** +``` +šŸ” Running cross-language compatibility checks... +āœ… Java type definitions: 47 types validated +āœ… TypeScript mappings: 47/47 compatible +āœ… C# mappings: 47/47 compatible +āœ… Schema checksums match +āœ… API surface compatible across all languages +šŸŽ‰ All compatibility checks passed! +``` + +### **Troubleshooting Compatibility Issues** + +If compatibility checks fail, you'll see detailed error reports: + +``` +āŒ Compatibility check failed! + +Issue 1: Type mapping mismatch + Field: NumericField.SUBTYPE_NUMERIC + Java: Integer + TypeScript: number āœ… + C#: int āœ… + Problem: Java uses boxed type, should use int for consistency + +Issue 2: Missing TypeScript definition + Field: DecimalField.SUBTYPE_DECIMAL + Java: BigDecimal āœ… + TypeScript: āŒ No mapping defined + C#: decimal āœ… + Fix: Add mapping in HelperRegistry.getLanguageType() +``` + +**Common Fixes:** +1. **Update CrossLanguageTypeCompatibilityTest.java** - Add new type mappings +2. **Update HelperRegistry.java** in codegen-mustache - Add language type helpers +3. **Check MetaDataProvider** - Ensure all types are registered in the registry +4. **Re-run validation** - `cd metadata && mvn test -Dtest=CrossLanguageTypeCompatibilityTest` + +**Test Location:**
