Virtual C
Virtual C is the name of a custom C++-like syntax that we developed to support some Object Oriented Programming features in VUEngine.
It consist of a set of scripts that act together as a transpiler that converts code writen in Virtual C to standard C.
# Features
Virtual C supports the following usual OOP features:
And adds a few features of its own:
# Limitations
Virtual C doesn’t support all of the common OOP concepts or common features of full blown OOP languages. Among those unsupported are:
- Multiple inheritance
- Public or private attributes
- Protected methods
- Stack allocated class instances
- Method/operator overloading
In Virtual C, all attributes are protected; while all methods are either public or private.
Another limitation is that all class instances have to be dynamically allocated since ClassName declares always a pointer and there is no mechanism to automatically call a constructor at the declaration of instances, therefore, there can no be instances allocated in the stack. But since Virtual C targets -for now- the Virtual Boy, and its CPU doesn’t have data cache, the performance impact is not as big as on architectures that have it.
