Book Description: Research Software Engineering: A Guide to the Open Source Ecosystem is a comprehensive guide that explores the principles and practices of software engineering in the context of research. The book covers the entire software development lifecycle, from planning and design to implementation, testing, and maintenance, with a focus on open source software development. It provides practical advice and examples from experienced researchers and developers, making it an essential resource for anyone involved in research software development. The book begins by discussing the importance of software engineering in research, highlighting the challenges faced by researchers who are not familiar with software development best practices. It then delves into the principles of software engineering, including modularity, abstraction, and testing, and how these principles can be applied to research software development. The authors also explore the benefits of using open source software, such as increased collaboration and reproducibility, and provide guidance on how to contribute to open source projects. The book then moves on to cover the different stages of the software development lifecycle, starting with planning and requirements gathering. The authors provide tips on how to identify the needs of your project, define scope, and create a project plan. They also discuss the importance of version control and how to use it effectively in your software development process. Next, the book covers the design phase, where the authors provide guidance on how to create a design that is flexible, modular, and maintainable. They also discuss the importance of documentation and how to write high-quality documentation that will help other developers understand and contribute to your codebase.
