Version 3.0

  • Moved to C++17 as minimum supported standard C++ version.
  • Reworked the whole library to be able to use it without c++ exceptions enabled.
  • Breaking Change: The method Stack<T>::push now takes a std::error_code& as last parameter and returns a bool.
  • Breaking Change: The class LuaException has been reworked and it now take a std::error_code instead of a int.
  • Breaking Change: The class LuaException is now thrown if a unregistered class is pushed via the Stack class, also when calling LuaRef::operator(), but only if exceptions are enabled.
  • Breaking Change: LuaRef::operator() now returns the class LuaResult, where it is possible to obtain the call results or error message.
  • Breaking Change: LuaBridge does not silently enable exceptions when calling getGlobalNamespace. Call enableExceptions(lua_State*) if you want to enable them explicitly.
  • Breaking Change: Removed RefCounterPtr, maintaining the reference counts in a unsynchronized global table is not production quality.
  • Breaking Change: Removed Class<T>::addStaticData, it was just an alias for Class<T>::addStaticProperty.
  • Breaking Change: Removed Class<T>::addCFunction, it was just an alias for Class<T>::addFunction.
  • Breaking Change: Removed Class<T>::addStaticCFunction, it was just an alias for Class<T>::addStaticFunction.
  • Allow specifying a non virtual base class method when declaring class members (functions or variables) not exposed in the inherited class.
  • Allow using capturing lambdas in Namespace::addFunction, Namespace::addProperty, Class<T>::addFunction, Class<T>::addStaticFunction, Class<T>::addProperty and Class<T>::addStaticProperty.
  • Added support for specifying factory functor in Class<T>::addConstructor to do placement new of the object instance.
  • Added Namespace::addVariable to allow adding a modifiable value by copy into the namespace without incurring in function calls or metatables generation.
  • Added getNamespaceFromStack function to construct a namespace object from a table on the stack.
  • Added registerMainThread function especially useful when using lua 5.1 to register the main lua thread.
  • Added std::shared_ptr support for types intrusively deriving from std::enable_shared_from_this.
  • Added Class<T>::addFunction overload taking a lua_CFunction as if it were a member.
  • Added Class<T>::addIndexMetaMethod to allow register __index metamethod fallback on a registered class.
  • Added Class<T>::addNewIndexMetaMethod to allow register __newindex metamethod fallback on a registered class.
  • Added LuaRef::isValid to check when the reference is a LUA_NOREF.
  • Added LuaRef::isCallable to check when the reference is a function or has a __call metamethod.
  • Added LuaException::state to return the lua_State associated with the exception.
  • Added support for std::byte as stack value type.
  • Added support for std::string_view as stack value type.
  • Added support for std::tuple as stack value type.
  • Added support for std::optional as stack value type.
  • Added support for std::set as stack value type by using LuaBridge/Set.h.
  • Added support to LuaRef for being hashed with std::hash (LuaRef properly usable in std::unordered_map).
  • Added single header amalgamated distribution file, to simplify including in projects.
  • Added more asserts for functions and property names.
  • Renamed luabridge::Nil to luabridge::LuaNil to allow including LuaBridge in Obj-C sources.
  • Removed the limitation of maximum 8 parameters in functions.
  • Removed the limitation of maximum 8 parameters in constructors.
  • Removed Class<T>::addData, it was just an alias for Class<T>::addProperty.
  • Removed TypeList from loki, using parameter packs and std::tuple with std::apply.
  • Removed juce traces from unit tests, simplified unit tests runs.
  • Changed all generic functions in LuaRef and TableItem to accept arguments by const reference instead of by copy.
  • Fixed issue when LuaRef::cast<> fails with exceptions enabled, popping from the now empty stack could trigger the panic handler twice.
  • Fixed unaligned access in user allocated member pointers in 64bit machines reported by ASAN.
  • Fixed access of LuaRef in garbage collected lua_thread.
  • Included testing against Luau VM
  • Bumped lua 5.2.x in unit tests from lua 5.2.0 to 5.2.4.
  • Bumped lua 5.4.x in unit tests from lua 5.4.1 to 5.4.6.
  • Run against lua 5.3.6 and 5.4.6 in unit tests.
  • Run against Luau and LuaJIT in unit tests.
  • Converted the manual from html to markdown.
  • Small improvements to code and doxygen comments readability.
  • Support for __fastcall function pointers.
