Rouvoet, A.J. (author), Poulsen, C.B. (author), Krebbers, R.J. (author), Visser, Eelco (author)An intrinsically-typed definitional interpreter is a concise specification of dynamic semantics, that is executable and type safe by construction. Unfortunately, scaling intrinsically-typed definitional interpreters to more complicated object languages often results in definitions that are cluttered with manual proof work. For linearly-typed...working paper 2020

(author), Tolmach, Andrew (author), Visser, Eelco (author)DynSem is a domain-specific language for concise specification of the dynamic semantics of programming languages, aimed at rapid experimentation and evolution of language designs.

Van Der Lippe, Tim (author), Smith, Thomas (author), Pelsmaeker, Daniël (author), Visser, Eelco (author)In this paper, we report on our experience in teaching a course on concepts of programming languages at TU Delft based on Krishnamurthi's PAPL book with the definitional interpreter approach using Scala as meta-language and using the WebLab learning management system. In particular, we discuss our experience with encoding of definitional...conference paper 2016
