* feat(csharp): add C# MethodExtractor config (#573)
Add C# method extraction config mirroring the JVM pattern from PR #576.
Wire csharpMethodConfig into the C# language provider and add 18 tests
covering classes, interfaces, abstract classes, structs, records,
constructors, params/out/ref/optional parameters, sealed methods,
attributes, and visibility modifiers.
* fix(csharp): add destructor, operator, conversion operator, and in-param support
- Add destructor_declaration, operator_declaration, and
conversion_operator_declaration to methodNodeTypes
- Custom extractName for operators (e.g., "operator +", "implicit operator double")
- Fix extractReturnType for operator declarations (use type field, not returns)
- Add in modifier to parameter extraction (alongside out/ref)
- Add 4 new tests: destructor, operator+, implicit conversion, in parameter
* fix(csharp): add ref param test and document compound visibility limitation
- Add test for ref parameter modifier (was only testing out)
- Document that protected internal / private protected resolve to first modifier
* feat(csharp): support compound visibilities (protected internal, private protected)
- Add 'protected internal' and 'private protected' to FieldVisibility union
- Detect compound modifiers in both C# method and field extractors via
collectModifierTexts helper scanning adjacent modifier nodes
- Add 2 tests for compound visibility detection
* feat(csharp): primary constructors, virtual/override/async, primary fields
Address all known limitations from review:
- Primary constructor support (C# 12): add extractPrimaryConstructor to
MethodExtractionConfig and extractPrimaryFields to FieldExtractionConfig.
Record params become public readonly properties; class params become
private captured fields.
- Add isVirtual, isOverride, isAsync optional fields to MethodInfo,
MethodExtractionConfig, NodeProperties, and parse-worker propagation.
- Detect virtual/override/async modifiers in C# method config.
- Move collectModifierTexts to shared helpers.ts (deduplicate).
- Fix destructor name to ~ClassName (disambiguates from constructor).
- Add expression-bodied method test.
- 118 tests total across method + field extraction suites, all passing.
* fix(csharp): review round 2 — annotations, record_struct, grammar pin
- Fix primary constructor annotations: use [] instead of extracting
class-level attributes (C# has no syntax for ctor-specific attributes)
- Add record_struct_declaration to typeDeclarationNodes in both method
and field extractors, CLASS_CONTAINER_TYPES, and isRecord visibility check
- Pin tree-sitter-c-sharp version (^0.23.1) in params comment
* fix(csharp): complete record_struct query + label mapping, sealed override test
- Add record_struct_declaration capture patterns to tree-sitter-queries.ts
(type definition + primary constructor)
- Add record_struct_declaration → 'Struct' in CONTAINER_TYPE_TO_LABEL
- Assert isOverride: true alongside isFinal in sealed override test
* fix(csharp): record_struct label mismatch, add record struct + documented limitation tests
- Fix record_struct_declaration query tag: @definition.struct (not @definition.record)
to match CONTAINER_TYPE_TO_LABEL and prevent broken HAS_METHOD edges
- Add 3 record struct tests: isTypeDeclaration, method extraction, primary constructor
- Add documented limitation tests: partial method (isAbstract: false), generic type
parameter stripping (name excludes <T>)
* fix(csharp): remove record_struct_declaration — not a real tree-sitter node type
tree-sitter-c-sharp 0.23.1 parses 'record struct' as record_declaration
(absorbs the 'struct' keyword as an unnamed child token). The non-existent
record_struct_declaration in queries caused TSQueryErrorNodeType, breaking
ALL C# file processing.
Remove from: tree-sitter-queries.ts, typeDeclarationNodes in both
extractors, CLASS_CONTAINER_TYPES, and CONTAINER_TYPE_TO_LABEL.
Record struct types are already handled via record_declaration.
* feat(csharp): add isPartial support, filter targeted attributes, static ctor test
- Add isPartial optional field to MethodInfo, MethodExtractionConfig,
NodeProperties, and parse-worker propagation pipeline
- Detect partial modifier in C# config — marks both declaration-only
and implemented partial methods
- Filter targeted attribute lists (e.g. [return: MarshalAs(...)]) in
extractCSharpAnnotations — only untargeted attributes collected
- Add static constructor test (isStatic: true, same name as class)
- Add 3 partial method tests: declaration-only, with body, coexisting pair
- Document record_struct/record_class as defensive dead code in
export-detection.ts (grammar absorbs keywords into record_declaration)
* fix(csharp): this param for extension methods, dedup visibility, test fixes
- Handle this modifier on extension method parameters (type prefixed
as 'this string', consistent with out/ref/in handling)
- Deduplicate visibility logic in extractPrimaryConstructor — reuse
csharpMethodConfig.extractVisibility instead of inline compound check
- Fix record struct test title to reflect actual grammar behavior
- Add conversion operator returnType assertion
- Add extension method this parameter test
* fix(csharp): primary constructor line points to param list, empty name guard
- Use paramList.startPosition instead of ownerNode.startPosition for
primary constructor line number (avoids methodInfoCache key collision)
- Guard against empty param names from tree-sitter error recovery nodes
