"Meson Build System Essentials" "Meson Build System Essentials" is an in-depth guide delivering everything software engineers, DevOps professionals, and open-source contributors need to master the Meson build system. The book opens with a clear exploration of Meson's design philosophy, its domain-specific language (DSL), and its compelling benefits over traditional build systems like Make, Autotools, and CMake. Readers gain a solid foundation in Meson's abstracted support for various languages and platforms, complemented by an overview of its vibrant ecosystem and community-driven resources such as WrapDB. The text then methodically guides readers through practical project structuring, from the anatomy of meson.build files and hierarchical codebases to powerful dependency management and reproducibility strategies. In-depth chapters detail essential techniques for configuring, generating, and managing builds-including build directory organization, toolchain abstractions, and advanced integrations with external tools and continuous integration frameworks. Readers learn how to define complex targets, manage resources, and scale Meson to large codebases with intricate dependencies and multi-platform requirements. Advanced users will appreciate comprehensive coverage of cross-compilation, custom toolchain configurations, automated testing, security assurance, and integration with modern DevOps workflows such as CI/CD pipelines and containerized environments. The book concludes with best practices for maintainable build patterns, legacy project migration, and perspectives on the future of build automation, enriched by real-world case studies and guidance on contributing to Meson's dynamic community. Whether maintaining robust software at scale or embracing modern development pipelines, this book is an authoritative companion for leveraging Meson's full potential.
