Overview

C header files parser. A try to automate import function declaration for node-ffi from C header files.

The general idea is having C header like this .h:

doubledo_some_number_fudging(doublea, intb);
myobj*create_object();
doubledo_stuff_with_object(myobj*obj);
voiduse_string_with_object(myobj*obj, char*value);
voiddelete_object(myobj*obj);

to get imported library with JavaScript code like this

varlibMylibrary=ffiCparser.import('libmylibrary','sample.h')

Header adaptation

It looks like direct use of C header files is not possible as that would require preprocessing. So module will rather use specially adapted header files made by copy/pasting needed declarations from real ones.

Defines

Maybe support of parsing #define directives will be needed as usefull constants usually defined in header files with that directive. So use case of module will change like that:

varlibDefinition=ffiCparser.parse('sample.h'),libMylibrary=ffi.Library('libmylibrary',libDefinition.functions),dbl=libMylibrary.do_some_number_fudging(0.5,libDefinition.defines.SOME_INTEGER_DEFINITION);

Current state

Still working on proper PEGJS grammar to get suitable C parser. Library ffiCparser is not ready yet.
