> Represents a type that was referred to using an elaborated type keyword, e.g., `struct S`, or via a qualified name, e.g.,` N::M::type`, or both. - Supporting Elaborated types allows for a greatly expanded library generation. - Can be used by `ffi-generate` (with Elaborated type support) to regenerate the `lib/dynamic_clang.js`; see the `llvm-clang-6.0` branch. See - https://clang.llvm.org/doxygen/classclang_1_1ElaboratedType.html - https://github.com/joelpurra/node-libclang/tree/llvm-clang-6.0 - https://github.com/joelpurra/node-ffi-generate/tree/support-elaborated-type
- Generated using `node-ffi-generate` with elaborated type support.
- Uses `clang-6.0`, which was released 2018-03-08.
- Has not been tested with older `clang`/`llvm` versions.
- Built on Ubuntu 19.10 Eoan using from `node-ffi-generate` with support for Elaborated types.
```shell
ln --symbolic --force "$(which "llvm-config-6.0")" "${HOME}/bin/llvm-config"
llvm-config --version
LD_LIBRARY_PATH="$(llvm-config --libdir)" node ./lib/generateffi.js
```
NOTE: move the generated `newclang.js` to replace `lib/dynamic_clang.js`.

- The code executes on `clang-6.0`. - The fix makes it possible to use `clang-9`, the current major release. See - https://clang.llvm.org/
- Uses `clang-9` to regenerate support for itself.
- Version 9 is the most recent major version, released 2019-09-19.
- Has additional methods not supported by `clang-6.0` (the only other version tested).
- Dynamically targeting the right version might be possible, but also requires more effort in generation and tests.
- Cross-generation between versions might be possible.
- Built on Ubuntu 19.10 Eoan using from `node-ffi-generate` with support for Elaborated types.
```shell
ln --symbolic --force "$(which "llvm-config-9")" "${HOME}/bin/llvm-config"
llvm-config --version
LD_LIBRARY_PATH="$(llvm-config --libdir)" node ./lib/generateffi.js
```
NOTE: move the generated `newclang.js` to replace `lib/dynamic_clang.js`.

- The original `ffi`, `ref`, and `ref-*` packages are outdated and unmaintained. - Fixes build/compatibility problems with Node.js v12+. - Uses `node-ffi-napi`. - Uses the dependency injection (DI, `-di` suffix) versions of `ref-*` with `ref-napi`. - Tested with Node.js v10 and v12, the currently supported LTS versions. See - https://github.com/node-ffi-napi - https://github.com/nodejs/Release
- Functions used in callbacks need to store an external reference to avoid getting garbage collected. - This patch by @atishay is a backport of the fix in the original `ffi`, which was removed by the `ffi-napi` maintainer. - Revert to using the official version published to npm when the fix is in place. See - node-ffi-napi/node-ffi-napi#56 - atishay/node-ffi-napi@40443ca
