Book Description

Haskell is a purely functional language that has the great ability to develop large and difficult, but easily maintainable software.

Haskell Cookbook provides recipes that start by illustrating the principles of functional programming in Haskell, and then gradually build up your expertise in creating industrial-strength programs to accomplish any goal. The book covers topics such as Functors, Applicatives, Monads, and Transformers. You will learn various ways to handle state in your application and explore advanced topics such as Generalized Algebraic Data Types, higher kind types, existential types, and type families. The book will discuss the association of lenses with type classes such as Functor, Foldable, and Traversable to help you manage deep data structures.

With the help of the wide selection of examples in this book, you will be able to upgrade your Haskell programming skills and develop scalable software idiomatically.

What you will learn

Use functional data structures and algorithms to solve problemsUnderstand the intricacies of the type systemCreate a simple parser for integer expressions with additionsBuild high-performance web services with HaskellMaster mechanisms for concurrency and parallelism in HaskellPerform parsing and handle scarce resources such as filesystem handlesOrganize your programs by creating your own types and type classes

About the Author

Yogesh Sajanikar has received his bachelor's degree in Mechanical Engineering from Shivaji University, India, along with a gold medal and a master's degree in Production Engineering from the Indian Institute of Technology, Bombay, India.

Yogesh has an experience of more than 20 years, and he has extensively worked with Product Lifecycle Management (PLM) and Computer Aided Design (CAD) software development firms, and architected solutions for domains such as Construction and Shipping Domain.

Having hooked on to functional programming, he moved into the Finance domain and worked as an enterprise architect; he has also worked with Scala/F# and Haskell. Currently, he is working as a CTO for a startup. He has also started local Haskell meetups and has been an active participant in meetups and functional conferences.

Yogesh believes in the open source movement, and believes in giving back to the open source community.
