Explore your Haskell Ecosystem with real world applications
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
What You Will Learn
- 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
