The cffi module gives full control of a GTK widget to a third-party dynamic library, to create more complex modules using different programming languages.

Addressed by cffi/<name>

Some additional configuration may be required depending on the cffi dynamic library being used.

The classes and IDs are managed by the cffi dynamic library.

~/.config/waybar/config

"cffi/c_example": {
    "module_path": ".config/waybar/cffi/wb_cffi_example.so"
}

CFFI modules require a handful of functions and constants to be defined with C linkage. The method to achieve this depends on the programming language being used (search for FFI / Foreign Function Interface).

An example written in C can be found in resources/custom_modules/cffi_example/

The list of symbols to define can be found in resources/custom_modules/cffi_example/waybar_cffi_module.h
