The feature allows documentation to be inherited from base classes, implemented interfaces, or explicitly referenced symbols. - -## Research Summary - -### C# Behavior (from Microsoft Learn) -- `` allows inheriting documentation from base members or interfaces -- Supports `cref` attribute to explicitly specify the source: `` -- Supports `path` attribute for XPath filtering: `` -- C# compiler copies the tag literally to XML output files (doesn't expand it) -- IDE (Visual Studio) expands inheritdoc for IntelliSense tooltips at design time -- External tools (DocFX, Sandcastle) expand inheritdoc in generated documentation - -### Roslyn Implementation (from GitHub research) -Located in: `src/Workspaces/Core/Portable/Shared/Extensions/ISymbolExtensions.cs` -- `GetDocumentationComment()` method with `expandIncludes` and `expandInheritdoc` parameters -- Expansion happens in Workspace layer, not compiler layer -- Supports both implicit inheritance (from overrides/interfaces) and explicit (via `cref`) -- XPath support for `path` attribute using `System.Xml.XPath` -- Cycle detection to prevent infinite recursion - -## Requirements - -### 1. Must Support Both IL and Current Compilation -- **IL symbols**: Documentation from referenced assemblies (`.xml` files) -- **Current compilation**: Documentation from symbols in the same project -- Use `InfoReader.TryFindXmlDocByAssemblyNameAndSig` for external symbols -- Access `.XmlDoc` property directly for internal symbols - -### 2. Must Work in Two Contexts - -#### A. XML File Production (`WriteXmlDocFile`) -- Expand `` when writing `.xml` documentation files -- This is the compile-time path (when building with `--doc` flag) -- Location: `src/Compiler/Driver/XmlDocFileWriter.fs` - -#### B. Design-Time Tooltips (`GetXmlCommentForItem`) -- Expand `` for IDE tooltips/IntelliSense -- Works even when no `.dll` or `.xml` is written -- Location: `src/Compiler/Symbols/SymbolHelpers.fs` - -### 3. Inheritance Resolution Rules -- **Implicit** (no `cref`): Inherit from overridden base method or implemented interface member -- **Explicit** (`cref` specified): Inherit from specifically referenced symbol -- **Filtered** (`path` specified): Use XPath to select specific parts (e.g., `` only) - -## Implementation Checklist - -### Phase 1: Parser Implementation ✅ -- [x] Create `XmlDocSigParser.fsi` and `XmlDocSigParser.fs` -- [x] Parse doc comment IDs (format: `M:Namespace.Type.Method`, `T:Namespace.Type`, etc.) -- [x] Add to project file before SymbolHelpers -- [ ] **TEST**: Add unit tests for parsing various doc comment ID formats -

- [ ] Resolve internal F# method - - [ ] Resolve external .NET type (from System) - - [ ] Resolve external .NET method - - [ ] Resolve generic type - - [ ] Resolve generic method - - [ ] Handle unresolvable cref (emit warning) - -### Phase 4: Implicit Target Resolution -- [ ] **IMPLEMENT**: `findImplicitTarget` function - - [ ] For `ValRef`: Check `MemberInfo.ImplementedSlotSigs` for interface implementations - - [ ] For `ValRef`: Check `IsDefiniteFSharpOverrideMember` for overrides - - [ ] For `TyconRef`: Check `tcaug_super` for base class - - [ ] Return `None` if no implicit target found -- [ ] **TEST**: Implicit target resolution tests - - [ ] Find interface method being implemented - - [ ] Find base class method being overridden - - [ ] Find base class for type - - [ ] Return None when no base/interface exists - -### Phase 5: Integration with XmlDocFileWriter -- [x] Update `WriteXmlDocFile` signature to accept `InfoReader` -- [x] Update call site in `fsc.fs` -- [ ] **IMPLEMENT**: Create proper `XmlDocTarget` from `Val`/`Tycon`/etc - - [ ] Build ValRef from Val (need to track parent entity) - - [ ] Build TyconRef from Tycon - - [ ] Build UnionCaseRef from UnionCase - - [ ] Build RecdFieldRef from RecdField -- [ ] **IMPLEMENT**: Call `expandInheritDoc` before writing XML -- [ ] **TEST**: End-to-end XML generation tests -

-## Technical Challenges to Resolve - -### Challenge 1: Type Accessibility -**Problem**: `ValRef`, `TyconRef`, `InfoReader` are internal types -**Solution**: Keep expansion logic internal, don't expose in public module signatures - -### Challenge 2: Val -> ValRef Conversion -**Problem**: In `WriteXmlDocFile` context, we have `Val` but need `ValRef` -**Solution**: -- Track parent entity context during traversal -- Construct ValRef using parent TyconRef -- Alternative: Pass ValRef from call sites instead of Val - -### Challenge 3: Namespace Issues -**Problem**: `FSharp.Compiler.Symbols` not accessible from Driver -**Solution**: Move types to TypedTree or use fully qualified names - -### Challenge 4: Phase Mismatch -**Problem**: XML generation is post-type-checking -**Solution**: Pass InfoReader through the call chain to enable symbol resolution - -## Testing Strategy - -### Unit Tests -- Test parser in isolation -- Test expansion logic with mock XML -- Test symbol resolution with known types -- Test XPath filtering - -### Component Tests -- Test realistic F# code scenarios -- Test cross-assembly scenarios -- Test IDE tooltip scenarios -- Test XML file generation - -### Integration Tests -- Build real projects with inheritdoc -- Verify .xml output matches expectations -- Test in VS Code/Visual Studio - -## Success Criteria -1. ✅ Code builds without errors or warnings -2. ❌ All unit tests pass -3. ❌ All component tests pass -4. ❌ XML files generated correctly at compile time -5. ❌ Tooltips show inherited docs at design time -6. ❌ Works with both IL and F# symbols -7. ❌ Handles cycles without hanging -8. ❌ Emits appropriate warnings for errors -
