Status of the Header File Import

We have always said that we will provide an automatic import for existing C header files so you can call into 3rd party libraries. We have now finished the importer to the point where it can import structs, typedefs and function signatures — in effect, all the regular C stuff.

However, C header files can contain all kinds of weirdnesses: macro definitions, macro definitions being called from within the same header, #defines that use expressions, non-volatile memory layout definitions and of course #ifdefs. These turn out to be non-trivial to handle. However, we think we have found reasonable ways of addressing all of them and we are confident we’ll have a working solution within weeks.

In fact, we are currently in the process of starting the first real-world application projects with mbeddr, and the headers used in these projects drive the implementation of the importer. We aren’t quite there yet, but we are making good progress.
