* fix(cpp): resolve explicit operator calls (a.operator+(b)) to the operator method (#1247) tree-sitter-cpp can't parse an operator_name in field position: the call_expression carries `function: <receiver>` plus an ERROR child wrapping the operator_name instead of a field_expression callee, so the extractor emitted a calls ref named just the receiver (`a`) and the edge never resolved — while the operator method itself indexed fine. Two-part fix, scoped to the explicit call form (infix `a + b` / `a[i]` need receiver type inference and are tracked in #1258): - extraction: recover the operator_name from the ERROR child and emit `<receiver>.operator+` (`->` receivers normalized, `this->` emits the bare name), like any other member call - resolution: matchMethodCall's dot pattern now admits an operator method part (cpp-gated; symbol chars failed the \w match), so receiver-type inference + resolveMethodOnType validate the target — a same-named operator on an unrelated class can't capture the edge Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cpp): harden explicit operator-call recovery against real-world shapes (#1247) Validated on nlohmann/json (dozens of explicit operator[] / operator* / operator< call sites). Two refinements the synthetic fixtures missed: - normalize spaced call-site operator names (`it.operator * ()`, `other.operator < (*this)`) to the compact form definitions index as - drop the ref for a complex receiver (`obj()->operator+`, member chains ending in a call) instead of emitting a bare operator name: exact-name fallback GUESSED among unrelated same-named operators (linked a std::map operator[] call to an in-repo operator[]) — silent miss, never a wrong edge Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
