Jason Hemann – författare

A new edition of a book, written in a humorous question-and-answer style, that shows how to implement  and use an elegant little programming language for logic programming.

The goal of this book is to show the beauty and elegance of relational programming, which captures the essence of logic programming.  The book shows how to implement a relational programming language in Scheme, or in any other functional language, and demonstrates the remarkable flexibility of the resulting relational programs. As in the first edition, the pedagogical method is a series of questions and answers, which proceed with the characteristic humor that marked The Little Schemer and The Seasoned Schemer. Familiarity with a functional language or with the first five chapters of The Little Schemer is assumed. 

For this second edition, the authors have greatly simplified the programming language used in the book, as well as the implementation of the language. In addition to revising the text extensively, and simplifying and revising the “Laws” and “Commandments,” they have added explicit “Translation” rules to ease translation of Scheme functions into relations.

This book constitutes the refereed proceedings of the 25th International Symposium on Trends in Functional Programming, TFP 2024, held in South Orange, NJ, USA, during January 10–12, 2024.

The 10 full papers included in this book were carefully reviewed and selected from 14 submissions. Topical sections as follows: dependent type systems; compiler optimizations; and DSL design and implementation.
