SqClassDef has been given + a second template argument to account for this: + + struct SQClassDef<MyClass, TheBaseClass> ... + + - The name of the class (in SqClassDef) can be filled in by SqPlus now, + if Squirrel class name is same as C++ class name: + + SQClasDef<Troll, Creature>("Troll", "Creature").func(...) => + SQClasDef<Troll, Creature>().func(...) + + - Code to handle class types (names, copy funcs, ID tag, ...) has been + collected in ClassTypeBase and ClassType<T>. + + - A new macro to specify that classes should not be copied with default + C++ method: DECLARE_NONCOPY_TYPE(ClassThatCannotBeCopied). + + - Reworked body of repetetive template functions, Moved to + SqPlusCallTemplates.h. Can be included with different qualifiers + (const, cdecl). + + - Support for cdecl member functions (MSVC specific) through: + + SQPLUS_ENABLE_CDECL_MEMBER_FUNCTIONS + + cdecl functions are compatible across compilers, while thiscall + is not. + + - Generic Push/Pop/Match handlers: SQPLUS_USE_GENERIC_HANDLERS + By default, Push/Get/Match handlers are for a single type. This + adds a fallback level, so that `hierarchy wide' handlers can + be used (define for base class and let all derived classes use + just that). + + - For functions that return a pointer to a temporarary (such as + returning a SQDefCharBuf, a template mapper class: + + Temporary<T>::type + + was added. It can hold a temporary value while finishing a + SquirrelFunction call (before returning to C++). + + - Suppressing horrible warnings from Visual C++ about sprintf and related + functions (_CRT_SECURE_NO_DEPRECATE). + + + * SquirrelVM.h/.cpp + + - Changed SquirrelVM and SquirrelVMSys to make them hold a reference + on a SQVM so that ownership can be shared in a defined way. + + - SquirrelVMSys can be used as before to swap the `active' VM. + Now it holds a ref to a VM so that a VM is closed automatically + when switched out and there are no refs to any longer. (To hold a + VM ref in the application, simply use an instance of SquirrelVMSys). + + - NOTE: A VM created through sq_open() comes out with a reference + count of 1. A VM created with sq_newthread() arrives with a ref + count of 0. SquirrelVM will compensate for this. + + - Possibility to store a `sandbox VM'. This VM is not allowed to + access functions / classes bound with SqPlus and so can run more + untrusted scripts. + + - Hopefully these changes will not break current apps.
