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.
Richard Cook is a staff software engineer at Tableau Software and works on high-performance relational database systems. He works primarily in C++, but has experience in a broad range of languages and technologies. He is a keen user of Haskell in his spare time and is frequently able to apply his functional programming and Haskell experience to his daily work. He is organizer of the Seattle Area Haskell Users’ Group and an active member of the Seattle functional programming community. He is currently developing a machine-learning framework for Haskell. He has a deep interest in programming languages and type systems in general, having developed compilers and developer tooling in the past. He is also a keen user of Python and C# and works regularly on all major desktop operating systems and dabbles with web applications.
What you’ll 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
