Interfacing with Proof Assistants for Domain Specific Programming Using EventML

This paper presents a paradigm for using proof assistants in the programming process. We demonstrate how the programming language EventML provides a useful interface to proof assistants throughout code development. Enhancing the use of proof assistants in programming will make them more valuable and accessible to a large community. We designed EventML specifically to cooperate with proof assistants at every stage of program creation. It will help programmers ensure correctness, document the code, and support modifications and improvements. Cooperation is especially effective when the proof assistant and the programming language share the same type system and when the proof assistant can generate executable code for the programming language, as is natural for proof assistants using constructive type theories.
