A new book, Type-Driven Development with Idris has just been published by Manning Publications. Written by Dr Edwin Brady, the creator of Idris, Type-Driven Development with Idris teaches you how to improve the performance and accuracy of your programs by taking advantage of a state-of-the-art type system.

Type-driven development is an approach to programming that embraces types as the foundation of your code. It is based on the concept of “dependent types”, which allow you to express relationships and other assumptions directly in your code, and have these assumptions checked by the compiler. With this approach, you can define specifications early in development and write code that’s easy to maintain, test, and extend.

Dr Brady said:

“Idris arose as a result of my own research into program verification and language design with advanced type systems. After spending several years immersed in the concept of programming with dependent types, I felt there was a need for a language designed for developers and practitioners as well as researchers. By teaching the concept of type-driven development using Idris, the book aims to make state-of-the-art verification techniques accessible to software practitioners.”

The book is currently available via MANNING publications: https://www.manning.com/books/type-driven-development-with-idris. ePub and Kindle versions available from April 10th. The source code, chapter 1 and chapter 13 are available as free downloads.
