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 recurring theme in this chapter is to learn how to improve and gain more control over the visibility and accessibility of data and functions in the public API. By enforcing the access of the programming interface, we can guarantee how the program is utilized. Additionally, we can focus on testing the interface as advertised.

Currently, Julia provides little help in encapsulating implementation details within a module. While we can use the export keyword to expose certain functions and variables to the other modules, it is not designed to be an access control or data encapsulation feature. You can always peek into a module and access any variable or function even when they are not exported.

In this section, we will continue the trend and go over some strategies that we can use to limit access to variables or functions in a module. Here, we will use...
