This paper examines what is required to use Aldor libraries to extend Maple in an effective and natural way. This represents a non-traditional approach to structuring computer algebra software: using an efficient, compiled language, designed for writing large complex mathematical libraries together with a top-level system based on user-interface priorities and ease of scripting. Our method involves the generation of Maple, C and Aldor stub code, uses a number of supporting modules, and relies on an enhanced foreign function interface for Maple. Since the language models of Maple and Aldor differ radically, run-time code must implement a non-trivial semantic correspondence. The Aldor functions run tightly coupled to the Maple environment, able to directly and efficiently manipulate Maple data objects directly. We call the overall system {\sl Alma}. |
