RE: The Guile junk drawer and a C plea (was: [PATCH] Addnondestructive delq1, delv1, and delete1.)

>However, I personally hope that Guile will continue to be friendly towards those using it as an embedded language. There, a C API is important. There *is* a downside in moving to Scheme from that perspective, but that is fine as long as it is easy to call Scheme from C. The typical use case is when a binding in the application which use Guile as embedded language needs to manipulate Scheme data in its arguments in order to interpret them.

 

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.
