| 42 | :description "A Sensible Object Definition for C." |
| 43 | |
| 44 | :long-description |
| 45 | "This system implements a fairly simple, yet powerful object system for |
| 46 | plain old C. Its main features are as follows. |
| 47 | |
| 48 | * Multiple inheritance, done properly (unlike C++, say), with a |
| 49 | superclass linearlization algorithm, and exactly one copy of any |
| 50 | superclass's slots. |
| 51 | |
| 52 | * Method combinations, and multiple flavours of methods, to make mixin |
| 53 | classes more useful. |
| 54 | |
| 55 | * The default method combination doesn't depend on the programmer |
| 56 | statically predicting which superclass's method to delegate to. |
| 57 | Multiple inheritance makes this approach (taken by C++) fail: the |
| 58 | right next method might be an unknown sibling, and two siblings might |
| 59 | be in either order depending on descendents. |
| 60 | |
| 61 | * Minimal runtime support requirements, so that it's suitable for use |
| 62 | wherever C is -- e.g., interfacing to other languages." |
| 63 | |
| 64 | ;; And now for how to build it. |
| 65 | ;; |
| 66 | ;; The big tables in parser.lisp need to be earlier. CLEAR-THE-DECKS ought |
| 67 | ;; to do more stuff, including calling BOOTSTRAP-CLASSES. Generally, the |
| 68 | ;; code isn't very well organized at the moment. |
