I'm trying to do something which should be very simple, but I'm not
having much luck figuring out how from the existing documentation.
For a python 2 project I am trying to return a gettext-translated string
as a unicode instance to python. The return value for gettext() is a
UTF-8 encoded char*, which should be pretty simple to convert to a
python unicode instrance using PyUnicode_FromString. I have a feeling
this is trivial to do, but I can't seem to figure out how.
According to http://docs.python.org/c-api/unicode.html , this is exactly what
PyUnicode_FromString is supposed to do.
What's the problem? Do you get an error? Some code might help.
For a single unicode instance this is indeed working correctly.
Unfortunately it breaks down when I need to return a list of unicode
instances. My simple approach looks like this:
boost::python::list PyMyFunc() {
std::vector<std::string> raw_strings = BaseClass::MyFunc();
std::vector<std::string>::const_iterator i;
boost::python::list result;
for (i=raw_strings.begin(); i!=raw_strings.end(); i++)
result.append(PyUnicode_FromString(i->c_str()));
return result;
}
but that results in a lot of compile errors suggesting that bp::list
does not know how to handle PyObject* values.
Wichert.
