Does anyone know if fixing these things would be possible? I am not to
familiar with decorators.
Two aspects of decorated functions annoy me. First off, the function name is
changed to the name of the decorated function. The result is that tests that
have @XFAIL show up as func_wrapper in bin/test -v. For example:
$./bin/test sympy/solvers/tests/test_ode.py -v
============================= test process starts ==============================
executable:
/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python
(2.6.4-final-0)
sympy/solvers/tests/test_ode.py[36]
test_checkodesol ok
test_dsolve_options ok
test_classify_ode ok
func_wrapper f
func_wrapper f
func_wrapper f
[…]
Secondly, the whole slew of information that gathered by source(), help(), and
IPython's ? and ?? commands are gathered from the decorated function.
Actually, help() gives the correct docstring, but it gives the parameter values
of the decorated function. For example, diff() has @vectorize:
In [1]: source(diff)
In file: ./sympy/core/multidimensional.py
def wrapper(*args, **kwargs):
# Get arguments that should be treated multidimensional
[… This is the vectorize function]
Help on function diff in module sympy.core.multidimensional:
In [2]: help(diff)
diff(*args, **kwargs)
Differentiate f with respect to symbols.
[...The docstring is correct, but it should be diff(f, *symbols, **kwargs)]
So can we include something in these decorators to fix these things?
