Ok, it turns out this is possible using numpy.add_docstring()
the caveat is that there must be no previous docstring in the object.
Remember: this is only for adding docstrings to compiled extension
module objects at runtime.
Here is a small contrived example (untested):
#---------------------
# decorator.py
#---------------------
import numpy as np
class DocDeco(object):
def __init__(self, doc):
self.doc = str(doc)
def __call__(self, func):
np.add_docstring(func, self.doc)
return func
docdeco = DocDeco
#----------------------
# foo.py
#----------------------
from decorator import docdeco
@docdeco('''docstring goes here''')
def bar():
pass
