Native Go bindings for Clang's C API (libclang) for versions 5.0 through 11.0.

Refer to https://llvm.org for the latest clang versions and documentation.

This should still be considered alpha as the API deserves further cleanup. The error go type should be used more extensively. Enum types typically have an Invalid value which should be used to trigger an error return.

Forked from https://github.com/go-clang/v3.9 some years ago.

This first incorporated the clang-c headers from 5.0.0 and came with some necessary changes as a result. Some bug fixes and some API changes are also included.

The git log will show what has changed. Or the quick way for users of previous versions to incorporate this would be to change their import lines and see what no longer compiles. (Also using git log on the *_test.go and cmd examples shows what API changes were made to keep the tests passing.)

This fork was not meant to be completely backward compatible with the v3.9 repository. As with that repository, this comes with a liberal license and users are free to take any parts they like.

Usage hasn't changed drastically. Some return types have changed so that some Dispose calls could be done away with. Some return error values have been changed to be more go idiomatic. In at least one case, a routine's return values were swapped so the error result is second.

As before, an example on how to use the AST visitor of the Clang API can be found in /cmd/go-clang-dump/main.go

The v3.9 bindings were used as a base. The gen tool from github.com/go-clang was also used on the 3.9 headers to get a sense for what had to be manually changed when the v3.9 repository was created. The gen tool was used on the new headers which saved a considerable amount of time. A diff between 5.0 and 3.9 headers was done to see how the libclang API had changed and what might need to be accounted for manually.

Support for clang 6.0, 7.0, and 8.0 was added by hand by looking at the differences to the clang-c headers from one version to the next.

Unit tests were not added to keep up with the changes so the new code is largely untested.

Once you have downloaded the repository:

  source env.sh
  cd clang
  go install
  go test

  cd ../cmd/go-clang-dump
  go build
  go test

  cd ../go-clang-compdb
  go build
  go test

  cd ../go-clang-includes
  go build
  go test

  cd ../go-clang-globals
  go build
  go test

All builds done with go1.10. At the time, this was also found to build and test successfully with the new vgo command.

Built with with go1.12.7.
