From 7a22dd7ffdb22360abdd3be18e531f0fc6ece8f2 Mon Sep 17 00:00:00 2001 From: Scot Murphy Date: Sun, 18 Jan 2026 22:33:13 -0600 Subject: [PATCH 01/39] feat: Implement variable scope management and semantic analysis middleware - Added VariableScope class to manage named variables and support lexical scoping with shadowing. - Introduced Interpreter and InterpreterBuilder classes for orchestrating middleware and AST transformations. - Created ReferenceEqualityComparer for reference-based equality checks. - Developed SemanticAnalysisMiddleware to enrich AST nodes with semantic information. - Added SemanticExtensions for managing semantic analysis data in InterpretationContext. - Implemented custom transformer registry for handling specific node patterns. - Defined transformation pipeline interfaces and delegates for middleware processing. - Created LinqExpressionTransformer to convert AST nodes into LINQ expression trees. - Added TerminalTransformMiddleware to delegate transformations to the final transformer. - Established a transformation result cache to optimize repeated computations. --- MIDDLEWARE_INTERPRETER_EXAMPLES.cs | 394 ++++++ MIDDLEWARE_INTERPRETER_IMPLEMENTATION.md |

Deleted ClrTypeFieldInterpretationAccessor, ClrTypeIndexInterpretationAccessor, and ClrTypePropertyInterpretationAccessor as they are no longer needed. - Updated ITypeMember interface by removing the GetMemberAccessor method. - Refactored TypeDefinitionProviderCollection to implement ICollection for better collection management. - Cleaned up validation builders by removing unnecessary references to Poly.Interpretation.AbstractSyntaxTree. - Introduced new interfaces and classes for transformation middleware and semantic analysis, enhancing the interpretation pipeline. - Added LinqExpressionMiddleware for compiling AST nodes into LINQ expressions. - Implemented semantic analysis extensions for managing type and member resolution during interpretation. --- Poly.Benchmarks/FluentApiExample.cs | 339 +++++++++-------- Poly.Benchmarks/FluentBuilderExample.cs | 223 ++++++----- Poly.Benchmarks/Program.cs | 28 +- .../MiddlewareInterpreterIntegrationTests.cs | 3 +- Poly.Tests/Interpretation/CoalesceTests.cs | 2 +- .../Interpretation/FluentValueApiTests.cs | 3 +- Poly.Tests/Interpretation/TypeCastTests.cs | 33 +- .../TypeDefinitionProviderCollectionTests.cs | 14 +- .../Builders/MutationConditionBuilder.cs | 3 +- .../DataModelTypeDefinitionProvider.cs | 2 -

Variable Type Safety Validation -**Goal:** Prevent runtime type errors from variable reassignment. - -- Store declared type in `Variable` at construction -- Validate type compatibility on reassignment -- Use numeric promotion rules for compatible assignments -- Provide clear error messages for incompatible types - -**Impact:** Eliminates entire class of type-safety bugs. - -#### 2. Overload Resolution for Methods/Indexers -**Goal:** Support method/indexer overloading with proper resolution. - -- Implement C#-style overload resolution with type distance scoring -- Exact match: 0, Numeric promotion: 1, Implicit conversion: 2 -- Handle tie-breaking with specificity rules -- Support generic method instantiation - -**Impact:** Enables realistic method invocation scenarios. - -#### 3. Numeric Promotion in Comparison Operators -**Goal:** Allow mixed-type comparisons (int vs double, etc.). - -- Apply `NumericTypePromotion` to all comparison operators -- Promote both operands to common type before comparison -- Consistent behavior with arithmetic operators - -**Impact:** Natural comparisons work like C# (x > 5.5 where x is int). - -#### 4. Circular Reference Detection -**Goal:** Prevent stack overflow from circular variable references. - -- Track visiting variables in `InterpretationContext` -- Detect cycles during `GetTypeDefinition()` / `BuildExpression()` -- Provide clear error with reference chain path -- Use thread-local or context-scoped tracking - -**Impact:** Robust error handling, prevents crashes. - -#### 5. Member Resolution Disambiguation -**Goal:** Properly handle types with fields, properties, and methods of the same name. - -- Prioritize member types: Properties > Fields > Methods -- Document disambiguation behavior -- Support explicit member type selection if needed - -**Impact:** Predictable behavior with complex types. - -#### 6. Assignment Target Validation -**Goal:** Validate assignment targets at build time. - -- Only allow assignment to `Parameter` or mutable `Variable` -- Reject assignments to `Constant`, `Operator`, or uninitialized variables -- Clear error messages for invalid targets - -**Impact:** Catch errors early with clear diagnostics. - -### Medium Priority Enhancements - -#### 7. Multi-Dimensional Array Support -**Goal:** Support multi-dimensional and jagged arrays. - -- Accept multiple indices: `arr.Index(i, j)` β†’ `arr[i, j]` -- Use `Expression.ArrayIndex` with rank validation -- Handle both rectangular (`int[,]`) and jagged (`int[][]`) arrays - -**Impact:** Full array support for .NET scenarios. - -#### 8. Type Definition Lookup Fallbacks -**Goal:** Graceful handling of type resolution failures. - -- Fallback chain: registered providers β†’ CLR reflection β†’ error -- Handle generic types, nested types, dynamic assemblies -- Detailed error messages listing where type was searched - -**Impact:** Better error messages, robust type resolution. - -#### 9. Scope Exception Handling -**Goal:** Properly clean up scope state on exceptions. - -- Wrap scope operations in try/catch/finally -- Ensure PopScope() runs even on error -- Consider context reset/recovery methods - -**Impact:** Context remains usable after build errors. - -### Low Priority / Optimization - -#### 10.

-0600 Subject: [PATCH 35/39] feat: Introduce new type system with optional and primitive type references - Added `OptionalTypeReference` to represent nullable types in the AST. - Introduced `PrimitiveTypeReference` for referencing primitive types by ID, including nullable support. - Created `PropertyDefinitionNode` for defining properties in types, with support for default values and constraints. - Implemented `TypeDefinitionNode` to represent type definitions, including properties, methods, fields, and base types. - Developed `TypeDefinitionNodeAnalyzer` to extract and store type definitions from the AST. - Enhanced type resolution with support for new type references in `TypeResolver`. - Added `PrimitiveTypeId` and `TypeCategory` enums for better type classification. - Updated constraints to include applicability checks based on type categories. - Introduced `ConstraintApplicabilityException` for handling constraint application errors. - Enhanced LINQ expression generation with support for custom node compilers. --- Poly.Benchmarks/FluentBuilderExample.cs | 208 ++++++------- Poly.Benchmarks/Program.cs | 4 +- .../DataModeling/DataTypeBuilderTests.cs | 10 +-

Subject: [PATCH 38/39] feat: Introduce Domain Modeling components - Added DataPropertyPath for managing property paths. - Created DataType to define data types with properties, rules, and mutations. - Implemented DataTypeBuilder for constructing DataType instances fluently. - Developed DataTypeValidator to validate instances against defined rules. - Introduced DataModelMemberAccessAnalyzer for transforming member accesses in data models. - Added DataModelPropertyAccessor for accessing properties in dynamic objects. - Implemented DataTypeDefinition to represent data types in the introspection system. - Created mutation-related classes including Mutation, MutationParameter, and various effects. - Added validation classes for rule evaluation and error handling. - Introduced type expressions for modeling various data types including collections, enums, and maps. - Updated README to reflect changes in the data modeling structure. --- .github/copilot-instructions.md | 6
