This is the code repository for Hands-On Design Patterns and Best Practices with Julia , published by Packt.
Proven solutions to common problems in software design for Julia 1.x
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.
This book covers the following exciting features:
- Master the Julia language features that are key to developing large-scale software applications
- Discover design patterns to improve overall application architecture and design
- Develop reusable programs that are modular, extendable, performant, and easy to maintain
- Weigh up the pros and cons of using different design patterns for use cases
- Explore methods for transitioning from object-oriented programming to using equivalent or more advanced Julia techniques

All of the code is organized into folders. For example, Chapter02.
The code will look like the following:
abstract type Formatter end
struct IntegerFormatter <: Formatter end
struct FloatFormatter <: Formatter end
Following is what you need for this book: This book is for beginner to intermediate-level Julia programmers who want to enhance their skills in designing and developing large-scale applications.
With the following software and hardware list you can run all code files present in the book (Chapter 1-12).

- Page 39 and 49: Before running the using Calculator command, he/she can first go to the Pkg mode (by pressing the ] key) and then run the dev Calculator command. For example:
(@v1.4) pkg> dev Calculator
Path `/Users/tomkwong/.julia/dev/Calculator` exists and looks like the correct package. Using existing path.

Page 54: The
subtypetree
function does not work when there is cycle in the type hierarchy. It is generally not a problem with the exception that theAny
type is a subtype of itself. So, runningsubtypetree(Any)
would get into an infinite loop. Please see Chapter02/subtypetree2.jl for a more robust version. -
Page 219: The
vendor_id
of theTripPayment
has the wrong type. It should beInt
rather thanString

Page 249: The second image on page number 249 is incorrect. The correct image is as follows:
- Page 318, 352, 494: These pages contain typos where "accessor" was misspelled as "assessor".
