The article introduces Battery-Embed, a C++/CMake solution for easily embedding resource files at compile time. This library allows developers to embed files such as icons, images, shader code, and configuration files into their executables. The advantage of using Battery-Embed is that the embedded files become part of the application once compiled, eliminating the need to distribute them separately. Additionally, end users cannot modify the files once shipped. Battery-Embed is designed to be used as a standalone library for any project, not just those relying on Battery. It provides functions in CMake to mark files for embedding, automatically converts them to C++ byte arrays, and regenerates them whenever the file changes. This makes it convenient for developers to access the embedded files in their applications. Battery-Embed uses Python for file generation and is compatible with C++14. It offers an easy setup process and can be used in projects of any size.
