This might be a simple as letting the import code (e.g. at https://github.com/cython/cython/blob/master/Cython/Utility/ImportExport.c and everywhere it's called) allow and use relative imports. At a high level, the tricky part is that cimports are resolved at Cython complile time, then again at runtime. IIRC there is also some name unification that uses the absolute path (which might not turn out to matter, but something to be aware of and look into). In short, I don't think it'd be that hard, but it'd probably touch a larger spread of the codebase than the relative (non-c)import case. - Robert _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
