AngelScript 2.29.0 is here

Andreas Jonsson · 2014-07-04T19:40:57

After an unusually long period a new version is finally out. This version comes with a number of smaller enhancements. Too many to list here, so if you want details, please check the change list. The most important improvements are the following: A new flag to support C++ array types: asOBJ_APP_ARRAY. This flag introduced for C++ types like the following: 'typedef float vec3f[3]', as this kind of types didn't follow the ordinary calling convention for classes nor primitives. Thanks to GGLucas the script language now supports named arguments when calling functions. This means that you can now call a function using the following syntax: 'func(arg1 = expr, arg2 = expr2)' and so on. When this is done, the compiler will rearrange the arguments by their names so that the order matches the declaration. This works especially well together with default arguments, as you will be able to provide only a few of the arguments, leaving the rest with the default value. Also thanks to GGLucas the script language now supports auto types in variable declarations with initialization expressions. Just like in C++ the compiler will deduce the type of the variable from whatever type the expression evaluates too. I've implemented a new operator overload 'opHndlAssign'. Types registered with asOBJ_ASHANDLE should use this operator overload instead of the ordinary 'opAssign' to implement the handle assign operation. This together with an enhancement to asBEHAVE_VALUE_CAST to allow the generic form 'void f(?&out)' has allowed me to implement a nicer syntax for managing the values in the dictionary add-on: int val = int(dict['value']); dict['value'] = val + 1; obj @handle = cast<obj>(dict['handle']); if( handle is null ) @dict['handle'] = object; This should lend itself well for implementing a true 'variant' type. Perhaps that's even something I'll try for an upcoming release. The engine has a couple of new callbacks calls RequestContext and ReturnContext. These callbacks can be used to implement context pooling for better performance, and they can also be used to pre-configure contexts that will be used internally by the engine, e.g. to debug script class destructors called from the garbage collector. Jordi Oliveras Rovira has taken the time to implement support for functor calling conventions asCALL_THISCALL_OBJFIRST and asCALL_THISCALL_OBJLAST. These work similarly to the existing asCALL_THISCALL_ASGLOBAL where the application supplies the a pointer to the functor object that emulates the function/method that the script calls. With this it is now perfectly possible to use for example std::function to implement proxy/wrapper functions if so desired. Regards, Andreas
