Currently, there is some code to automatically generate Scheme bindings to C procedures (i.e. automatically generated scm_c_define_gsubr) (IIRC this is ‘snarfing’, but maybe that’s only a documentation thing). It is possible to call the Scheme procedures from C (scm_call + module reflection API to get the procedure), but AFAIK there is no mechanism yet for _automatically_ generating the C wrappers to Scheme things yet. For the embedded language case, it would be useful to have such an automatic generator. Best regards, Maxime Devos.
