Hands-On Design Patterns and Best Practices with Julia

By: Tom Kwong

Overview of this book

Design patterns are fundamental techniques for developing reusable and maintainable code. They provide a set of proven solutions that allow developers to solve problems in software development quickly. This book will demonstrate how to leverage design patterns with real-world applications. Starting with an overview of design patterns and best practices in application design, you'll learn about some of the most fundamental Julia features such as modules, data types, functions/interfaces, and metaprogramming. You'll then get to grips with the modern Julia design patterns for building large-scale applications with a focus on performance, reusability, robustness, and maintainability. The book also covers anti-patterns and how to avoid common mistakes and pitfalls in development. You'll see how traditional object-oriented patterns can be implemented differently and more effectively in Julia. Finally, you'll explore various use cases and examples, such as how expert Julia developers use design patterns in their open source packages. By the end of this Julia programming book, you'll have learned methods to improve software design, extensibility, and reusability, and be able to use design patterns efficiently to overcome common challenges in software development.

The parametric type pattern

Parametric type is a core language feature that's used to materialize data types with parameters. It is a very powerful technique because the same object structure can be reused for different data types in its fields. In this section, we will demonstrate how parametric types can be applied effectively.

When designing applications, we often create composite types to conveniently hold multiple field elements. In its simplest form, composite types only serve as the containers of fields. As we create more and more composite types, it may become clear that some of these types look almost the same. Furthermore, the functions that operate on these types may be very similar as well. We could end up with a lot of boilerplate code. Wouldn't it be cool to have a template that allows us to customize a general composite type for a specific use? ...
