New submission from Stefan Behnel <stefan_ml at behnel.de>:
The C-API function PyUnicode_Count(ustring, substring, start_index, end_index)
is unimplemented (has a stub in stubs.py). It should be rather straight forward,
given that there is an equivalent ustring.count(substring, start_index,
end_index) method.
Something like this might do the trick:
@cpython_api([PyObject, PyObject, Py_ssize_t, Py_ssize_t], Py_ssize_t, error=-1)
def PyUnicode_Count(space, w_str, w_substr, start, end):
"""Return the number of non-overlapping occurrences of substr in
str[start:end]. Return -1 if an error occurred.
This function returned an int type and used an int
type for start and end. This might require changes in your code for
properly supporting 64-bit systems.
"""
return space.call_method(w_str, "count", w_substr,
space.wrap(start), space.wrap(end))
