sp.h is the standard library that C deserves

clibrarydata-structuresopen-source

sp.h is a single-header C library introduced by the author at spader.zone/sp. It offers a wide range of data structures and utilities commonly found in higher-level languages, such as dynamic arrays (sp_array), hash maps (sp_map), string builders (sp_string), and optional types. The library is designed to be minimal and dependency-free, requiring only a C99 compiler. It aims to address common pain points in C programming, like manual memory management and lack of generic containers, by providing type-safe macros and automatic memory handling. The project is open-source and available on GitHub. Developers can integrate it by including the single header file. The library's performance is comparable to hand-tuned implementations, and it includes features like iterator support and error handling. This could significantly reduce development time for C projects that need robust data structures without pulling in heavy dependencies.

// why it matters

sp.h could make C development safer and more productive by providing modern data structures out of the box.
