Building an Application with Functional Haskell [Video]

More Information
  • Parse command-line options using the applicative style
  • Use strict and lazy file I/O
  • Handle the various common Haskell string types
  • Store structured data in readily parseable format such as YAML
  • Read/create/delete/update data items in your application
  • Important steps to take on your Haskell learning path while building your application

Haskell is a powerful and well-designed functional programming language designed to work with complex data. Its emphasis on "purity" makes it easier to create rock-solid applications which stay maintainable and error-free even as they grow in scale.

This video is specifically aimed at anybody who knows the essentials of the Haskell programming language and who is interested in moving onto developing real programs that will make use of file I/O, command-line parsers and various third-party packages.We will start by describing the kind of application that the developer will write. We will then see how we will cover the kind of user interface to expect and the types of data processing and handling that the program will do. We will be seeing the different ways to store data in our filesystem and interact with it. By the end of the course, we will have developed a fully-featured command-line utility program that can later be expanded by the developer in many ways

Style and Approach

This video will take you through the complete journey from writing your first Haskell program to getting familiarized with Haskell and all its functionalities. This tutorial will take a pragmatic approach to teaching you Haskell with an App example.One of the trademarks of this video is developing and building a Haskell app using a modern tool chain. Giving you a practical experience of functional programming with Haskell it will teach you to build your first functional application effortlessly

  • Get acquainted with real computer programs in Haskell and how to build professional applications
  • Apply the best practices in Haskell programming in your applications
  • Understand how data interacts in your Haskell App work and what pitfalls to avoid
