Objective:

Together with Prof. Dr. William R. Cook of the University of Texas at Austin, and Alex Loh, Tijs van der Storm has been designing and implementing a new programming system, called Ensō. Ensō is theoretically sound and practical reformulation of model-based development. It is based on model-interpretation as opposed to model transformation and code generation. Currently, the system already supports models for schemas (data models), web applications, context-free grammars, diagram editors and security.

Users:

All programmers.

Impact:

Ensō has the potential to revolutionize the activity of programming. By looking at model driven engineering from a completely fresh perspective, with as key ingredients interpreters and partial evaluation, it may make higher level (domain level) program construction and maintenance as effective as normal programming.

Competition:

Ensō competes as a programming paradigm with model driven engineering tools and generic programming and languages that provide syntax macros and language extensions.

Engineering:

Ensō is a completely self-hosted system in 7000 lines of code.

Novelties

• A compiler for a dedicated Ensō language, which targets JavaScript.

• Added a demo based on the LWC'13 questionnaire language assignment.
