libfoojarlibbarjar

libfoojarlibbarjar is a cross-language interoperability library that provides a unified runtime and API surface for loading and using components from the FooJar and LibBar ecosystems. It functions as a dynamic loader and binding layer, enabling applications to discover, instantiate, and interoperate with plugins and libraries across languages without requiring bespoke adapters for each pair of technologies.

The library exposes a compact C API backed by a language-agnostic metadata format. It includes a registry for modules, semantic versioning and ABI negotiation, and a dependency resolver to ensure compatible combinations of components. It also offers automatic binding generation and runtime shims to bridge calls between C, Python, Ruby and other supported languages.

Design goals include simplicity of integration, robust error reporting, and predictable resource lifetimes. libfoojarlibbarjar supports lazy loading, reference counting, and isolation of plugins to minimize crashes in host applications. It emphasizes deterministic behavior across platforms and toolchains.

Platform and licensing: It targets Linux, Windows, and macOS and is compatible with common toolchains such as GCC and Clang. The project provides MIT-style licensing and maintains a permissive distribution model. Bindings and adapters for Python and Ruby are maintained by the community, with ongoing work toward additional language bindings.

History and status: The project originated within the FooJar ecosystem and was published as open source in the early 2020s. As of 2024, libfoojarlibbarjar sees active development and regular releases, focusing on stability, performance, and improved developer ergonomics. See also: libfoo, libjar, libbar.
