Implementation of a Graphic Interface Development Tool for Prolog

Abstract

The work examines the current problems of the spread of use of logical programming in the development of commercial multi-platform software applications, tools for convenient development of a modern graphical interface to the logical programs. Libraries with similar concepts of use have been analyzed and described. The purpose of the proposed concept, which is implemented as an open source library, is described, and the advantages of the proposed tools over similar existing tools are indicated. The main feature and advantage of the proposed concept is the implementation of Prolog business logic and interface by means of JavaScript usage of child processes. The proposed concept of interface to Prolog takes full advantage of the possibilities provided by async await. A framework library has been created for the use of Logic Programming in graphical interface development without losses in the application performance. The paper describes the proposed concept and the developed framework (library). The ways to further improve the possibilities for expanding the purpose of the implemented library were identified. The directions of further simplification for programmers of integration of the graphic interface to logical programs have been defined. A significant advantage of the proposed tool is the easy-to-use functions to wrap and control the correctness of requests to the Prolog. The main goal of the library is to create an environment for the Prolog developers where they can create any type of software, which is meant to be user friendly, fast, and cross platform using modern and flexible. This concept also tries to solve disadvantages and architectural problems that were found in other libraries. The safety of library functionality has been analyzed. The concept of potential horizontal application scalability is described. Conclusions and future of libraries were introduced, in which the usage of TypeScript for type-safety and avoidance of run-time errors is mentioned. Overall, the library extends the use of Prolog beyond logical programming and takes a leap forward in its progress.
