Forked and fixed quite a few more things: https://github.com/node-ffi-packager/node-libclang


Note: includes commits from previous pull-requests. Should be merged to master one by one, but wanted to showcase the stepwise progress and allow for feedback.


  • 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.
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.

> 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.

Note that support for Elaborated types (#16) added 1200 or so new lines (100% increase) to lib/dynamic_clang.js. This includes enums and functions which were not exported before. Saw similar improvements for another library.
