Semantics Engineering with PLT Redex

Semantics Engineering with PLT Redex:

This text is the first comprehensive presentation of reduction semantics in one volume; it also introduces the first reliable and easy-to-use tool set for such forms of semantics. Software engineers have long known that automatic tool support is critical for rapid prototyping and modeling, and this book is addressed to the working semantics engineer (graduate student or professional language designer). The book comes with a prototyping tool suite to develop, explore, test, debug, and publish semantic models of programming languages. With PLT Redex, semanticists can formulate models as grammars and reduction models on their computers with the ease of paper and pencil.
The text first presents a framework for the formulation of language models, focusing on equational calculi and abstract machines, then introduces PLT Redex, a suite of software tools for expressing these models as PLT Redex models. Finally, experts describe a range of models formulated in Redex.
PLT Redex comes with the PLT Scheme implementation, available free at Readers can download the software and experiment with Redex as they work their way through the book.

For me this is a long, long, long goal :).

  1. Have you dug into SEwPR yet?
    I’m thinking of ordering a copy as well, and trying to relate it to what I’m seeing in “Concepts, Techniques, and Models of Computer Programming” (, which claims to provide a sort of Grand Unified Theory of Programming Languages: a framework for understanding how they all relate to eachother, and what techniques are effective in each. CTaMoCP has its own “kernel language” concept that seems to overlap with SEwPR, but I need to study them more closely to be sure.

    Have not yet but I can’t wait. Currently it is on my “priority” queue.
    I would love to hear how it goes for you.
    One note: the folks on the PLT Scheme mailing list field Redux questions all the time. It is really a great list, don’t hesitate to post any questions about the book or Redux. Here is the link to subscribe:
