  "message": "Support C++ 11 enum class generation via pure_enums\u003denum_class\n\nAdds C++ 11 `enum class` generation to the C++ code generator. When `pure_enums\u003denum_class` is specified, generates strongly-typed enums with proper scoping and type safety.\n\n## Code Generator Changes\n\n**Modified `t_cpp_generator.cc`:**\n- Added `gen_enum_class_` flag parsed from `pure_enums\u003denum_class` option\n- Modified `generate_enum()` to emit `enum class` when both `gen_pure_enums_` and `gen_enum_class_` are set\n- Fixed enum value scoping: use `static_cast\u003cint\u003e(Color::RED)` for array initialization\n- Fixed map operations: cast enum class to int in `find()` calls (no implicit conversion)\n\n**Test infrastructure:**\n- Created `t_cpp_generator_enum_class_tests.cc` with three test cases validating default, `pure_enums`, and `pure_enums\u003denum_class` behavior\n- Extracted common utilities to `t_cpp_generator_test_utils.h` (shared with `private_optional` tests)\n- Added expected output files: `expected_Color_{default,pure_enums,enum_class}.txt`\n\n**Build system:**\n- Added CMake compile-checks for generated code (both `private_optional` and `enum_class`)\n- Unified compile-check blocks with shared Boost detection\n- Ensures generated code compiles as part of standard test build\n\n## Usage\n\n```thrift\nenum Color {\n  RED \u003d 1,\n  GREEN \u003d 2,\n  BLUE \u003d 3\n}\n```\n\n```bash\nthrift --gen cpp:pure_enums\u003denum_class example.thrift\n```\n\nGenerates:\n```cpp\nenum class Color {\n  RED \u003d 1,\n  GREEN \u003d 2,\n  BLUE \u003d 3\n};\n```\n\nBackward compatible - existing behavior unchanged when option absent.\n\n---\n\n- [ ] Did you create an [Apache Jira](https://issues.apache.org/jira/projects/THRIFT/issues/) ticket?  ([Request account here](https://selfserve.apache.org/jira-account.html), not required for trivial changes)\n- [ ] If a ticket exists: Does your pull request title follow the pattern \"THRIFT-NNNN: describe my issue\"?\n- [x] Did you squash your changes to a single commit?  (not required, but preferred)\n- [x] Did you do your best to avoid breaking changes?  If one was needed, did you label the Jira ticket with \"Breaking-Change\"?\n- [ ] If your change does not involve any code, include `[skip ci]` anywhere in the commit message to free up build resources.\n\n---------\n\nCo-authored-by: copilot-swe-agent[bot] \u003c198982749+Copilot@users.noreply.github.com\u003e\nCo-authored-by: zsy056 \u003c1074382+zsy056@users.noreply.github.com\u003e",
