For the struct

struct s {
    char[4] array;
};

The following is being generated;

(cffi:destruct s
  (array (:pointer :char :count 4)))

It should be generating:

(cffi:destruct s
  (array :char :count 4))

Is there any reason why this is named managler and not mangler?

cl-bindgen always expands pointer types to the the type's full definition, i.e.

struct foo {
    struct other_thing *foo
};

always gets expanded to:

(defcstruct foo
  (foo (:pointer (:struct other-thing))))

However, this can be problematic if the other_thing type doesn't yet have (or won't ever) bindings generated for it. There should be a way to define a regex or some other matching function to tell cl-bindgen that some pointer types should not be expanded. The desired output would then be something like:

(defcstruct foo
    (foo :pointer #| (:struct other-thing) |#))

Structs like

struct foo {
    enum type flag;
    union {
        int a;
        double b;
    };
};

Thanks for this awesome library.

I discovered a minor inconvenience: when parsing a file like cuda.h quotes are not escaped in docstrings. So forms like the following are produced:

(cffi:defcfun "custreamgetcaptureinfo" CUresult
  "\brief Query capture status of a stream
 
  Query the capture status of a stream and and get an id for
  the capture sequence, which is unique over the lifetime of the process.
 
  If called on ::CU_STREAM_LEGACY (the "null stream") while a stream not created
  with ::CU_STREAM_NON_BLOCKING is capturing, returns ::CUDA_ERROR_STREAM_CAPTURE_IMPLICIT.
 
  A valid id is returned only if both of the following are true:
  - the call returns CUDA_SUCCESS
  - captureStatus is set to ::CU_STREAM_CAPTURE_STATUS_ACTIVE
 
  \return
  ::CUDA_SUCCESS,
  ::CUDA_ERROR_STREAM_CAPTURE_IMPLICIT
  \notefnerr
 
  \sa
  ::cuStreamBeginCapture,
  ::cuStreamIsCapturing"
  (hstream CUstream)
  (capturestatus (:pointer CUstreamCaptureStatus))
  (id (:pointer cuuint64-t)))

The problem is "null stream" where the quotes around it are not escaped.

Hi there, I'm just trying out your library, I wonder if this is expected behaviour with respect to the include guard at the top of the file? Many thanks!

clang -print-resource-dir prints out the resource directory of clang, which contains the include directory needed to find standard header files. Use this command to derive this at run-time instead of making the user do it themselves.
