Changelog

Unreleased

Added

  • CFFI.memcpy and CFFI.memmove for copying memory from one pointer to another
  • CFFI.memset to fill memory from a pointer with a single byte value
  • CFFI.memcmp and CFFI.memequal to compare memory from two pointers
  • Support for Android devices with 16KB page size

Fixed

  • macOS universal build for x86_64

Changed

  • Updated godot-cpp to branch godot-4.5-stable

0.2.0

Added

  • Support for accessing global variables with CFFILibraryHandle.get_global
  • CFFIType.alloc_array to allocate an array of values
  • CFFIPointer.duplicate_array to duplicate more than one element from a pointer as an CFFIOwnedValue
  • CFFIPointer.get_address method to get the base address of a pointer. Useful to compare pointers by value.
  • Support for passing CFFIFunctions as function pointers to struct fields or native function arguments.
  • Add CFFICallableFunction class that wraps Callable as native function pointers using libffi's closure API. They can be created using CFFIScope.create_function.
  • Support for passing any packed array (other than PackedStringArray) as pointer to native functions.
  • CFFIPointer.to_*_array methods for copying data from pointers as other types of packed arrays
  • StreamPeerCFFIPointer stream peer that handles a binary data stream from a CFFIPointer.

0.1.0

Added

  • CFFI singleton that represents the global type scope and is the entrypoint for opening native libraries
  • CFFILibraryHandle class representing native libraries, where native functions live
  • Custom ".ffilibrary" file format, which are INI files with a [libraries] section that defines paths to native libraries separately per platform/architecture, using the exact same format as ".gdextension" files. They are imported as CFFILibrary resources.
  • Editor export plugin that bundles the correct native library in builds, based on the configurations from ".ffilibrary" files
  • Support for built-in types like int and float, pointer types like const char * and struct types
  • Instantiate FFI types using CFFIType.alloc. The returned CFFIOwnedValue is RefCounted and releases the memory automatically whenever it gets destroyed.
  • Get/set struct fields by name from CFFIPointers
  • Construct Strings and PackedByteArrays from CFFIPointers with a single method call
  • Use Dictionaries as literal struct values, for example when calling a function
