Helping Wing Analyze Cython Code

Wing works best with Cython’s pure Python mode. In this case, the source code is stored in .py files, and source analysis works the same as it does in all other Python files. Debugging also works when the .py file is executed directly rather than compiling it. See Pure Python Mode for details on using Cython this way.

Cython-compiled modules that don't use pure Python mode are inspected in the same way as extension modules, which means that some type information, including name and type of arguments to functions, is unavailable. In that case, *.pyi files may be used to improve Wing's analysis of the interface in the module, as described in Defining Interface Files.

Wing cannot analyze .pyx files directly and uses the simplified non-Python completion support when working within those files.
