Dependent types are a concept that allows developers to write proof-carrying code. Idris is a
programming language that supports dependent types. This book will teach you the mathematical
foundations of Idris as well as how to use it to write software and mathematically prove
properties. The first part of the book serves as an introduction to the language's underlying
theories. It starts by reviewing formal systems and mathematical logical systems as
foundational building blocks then gradually builds up to dependent types. Next you'll learn
type theory for dependent types. Following this you'll explore the Idris programming language
and conclude by exploring the depths of formal systems and type checkers by implementing them.
Introduction to Dependent Types with Idris will walk you through simple examples through more
advanced techniques stepping up the difficulty as you gain more knowledge. Every chapter
includes a set of exercises based on what it covered to further cement your learning. No
specialized knowledge of mathematics is expected beyond the basics so it is perfect for
novices. What You Will Learn Understand Lambda calculus and dependent types Gain insight into
functional programming Write mathematical proofs with Idris Who This Book Is For Programmers
mathematicians academics and anyone else interested learning dependent types and lambda
calculus.
