Multiparadigm programming languages are a recent development in the realm of programming languages. A multiparadigm programming language allows the use of multiple, differing programming paradigms without departing from a single, unified linguistic framework. Multiparadigm programming languages are claimed to have benefits to both pedagogy and complex application creation. The beneficial claims of multiparadigm languages have yet to be validated. The availability of a programming environment would encourage and expedite academic and industrial validation.
Creating a programming environment is considered an extremely labor-intensive activity. Further complications arise from the fact that programming environment creation is an experimental activity: the component mix that best expedites program development in a new programming language cannot be predicted in advance. As a result, few new languages are ever verified in the context of a supportive programming environment. Leda, a unique programming language that includes the functional, imperative, logic and object-oriented paradigms, is at this juncture.
This thesis describes the structure of an environment framework that allows for experimental study of the necessary components of a multiparadigm programming language environment. New tools and techniques, as well as changes to traditional tools and techniques are required to allow programmers to abstract effectively across paradigms. This research examines the topic by creating LacEDAemon, a testbed programming environment for the multiparadigm programming language Leda, within the framework of a variety of integrated, cohesive tools. LacEDAemon relies on a hypertool-based toolkit integration framework architecture that affords both loose and tight control integration, as well as data integration, using existing, off-the-shelf tools written in a variety of programming languages.
Along with demonstrating the viability of hypertool integration as a low-cost approach for constructing programming environments, LacEDAemon provides a vehicle for: determining an effective multiparadigm programming toolset, studying multiparadigm program design, conducting studies of multiparadigm program visualization, exploring different strategies for software reuse, and examining the merits of conducting all programming activity within the database-centered environment approach. This environment also provides support for investigations in the areas of multiparadigm algorithms, multiparadigm software metrics, and multiparadigm program comprehension. Various techniques for evaluating integrated environments are also applied to LacEDAemon.
