Gain the skills to begin developing Raku applications from the ground up in this hands-on compact book, which includes a foreword from Larry Wall, creator of Perl. You'll learn enough to get started building with Raku, using Raku's gradual typing, handy object orientated features, powerful parsing capabilities, and human-usable concurrency. This book has been updated to include the latest version of Raku based upon the Perl 6.d major version which includes over 3,400 new commits in its specification. After a short introduction, each chapter develops a small example project, explaining the Raku features used. When the example is done, you'll explore another aspect, such as optimizing further for readability or testing the code. Along the way you'll see Raku basics, such as variables and scoping; subroutines; classes and objects; regexes; and code testing. When you've mastered the basics, Raku Fundamentals moves onto more advanced topics to give you a deeper understanding of the language. You'll learn, amongst other things, how to work with persistent storage, how to generate good error messages, and how to write tricky applications such as a file and directory usage graph and a Unicode search tool. What You Will Learn Get coding with latest version of Raku Work on several hands-on examples and projects Integrate Python libraries into your Raku-based programs Parse INI files using regexes and grammars Build a date-time converter Carry out refactoring and other automated tests Who This Book Is For If you already know one or more programming languages, and want to learn about Raku, then this book is for you.

Gain the techniques and tools that enable a smooth and efficient software development process in this quick and practical guide on Python continuous integration (CI) and continuous delivery (CD). Based on example applications, this book introduces various kinds of testing and shows you how to set up automated systems that run these tests, and install applications in different environments in controlled ways. Python Continuous Integration and Delivery tackles the technical problems related to software development that are typically glossed over in pure programming texts. After reading this book, you'll see that in today's fast-moving world, no software project can afford to go through development, then an integration phase of unpredictable length and complexity, and finally be shipped to the customer -- just to find out that the resulting application didn't quite fill their need. Instead, you'll discover that practicing continuous integration and continuous delivery reduces the risks by keeping changes small and automating otherwise painful processes. What You Will Learn Carry out various kinds of testing, including unit testing and continuous integration testing, of your Python code using Jenkins Build packages and manage repositories Incorporate Ansible and Go for automated packaging and other deployments Manage more complex and robust deployments Who This Book Is For Python programmers and operating staff that work with Python applications.
