wrapper

I am wrapping a C file so I can use it in python. The output of the C function is an array of doubles. I want this to be a numpy array in python. I get garbage. Here's an example that generates the error. First, the C file (focus on the last function definition, everything else should be OK): #include <Python.h> #include <numpy/arrayobject.h> #include <stdio.h> static char module_docstring[] = "docstring"; static char error_docstring[] = "generate the error"; static PyObject *_aux_error(PyObject *self, PyObject *args); static PyMethodDef module_methods[] = { {"error", _aux_error, METH_VARARGS,

I want to be able to wrap a PHP function by another function, but leaving its original name/parameter list intact. For instance: function A() { print "inside A()\n"; } function Wrap_A() { print "Calling A()\n"; A(); print "Finished calling A()\n"; } // <--- Do some magic here (effectively "A = Wrap_A") A(); Output: Calling A() inside A() Finished calling A() Apparently runkit might help you . Also, you can always do this the OO way. Put the original fun in a class, and the decorator into an extended class. Instantiate and go. Here is my method of mimicking decorators from python in php.

I have some classes that don't implement a certain interface but structurally comply to that interface. interface IFoo { void method(); } class Bar { // does not implement IFoo public void method() {...} } Now, I could write a wrapper around those classes that simply delegate to the wrapped class class BarWrapper : IFoo { Bar bar = new Bar(); public void method() { bar.method(); } } But that's lots of tedious work. Can those wrapper classes somehow be generated automatically? Something like: IFoo foo = CreateWrapper<IFoo>(new Bar()); I'm sure you could do this with Reflection.Emit but I've

This question already has an answer here: How to create a Python decorator that can be used either with or without parameters? 10 answers from functools import wraps def foo_register(method_name=None): """Does stuff.""" def decorator(method): if method_name is None: method.gw_method = method.__name__ else: method.gw_method = method_name @wraps(method) def wrapper(*args, **kwargs): method(*args, **kwargs) return wrapper return decorator Example: The following decorates my_function with foo_register instead of ever making it to decorator . @foo_register def my_function(): print('hi...')
