Is it unreasonable to promote bare format strings as candidates for
the docstring?
Yes it is. But being annoyed by this I've written this decorator:
def fmtdoc(func):
''' Decorator to replace a function's docstring with that string
formatted against the function's module's __dict__.
This supports simple formatted docstrings:
ENVVAR_NAME = 'FUNC_DEFAULT'
@fmtdoc
def func():
"""Do something with os.environ[{ENVVAR_NAME}]."""
print(os.environ[ENVVAR_NAME])
This gives `func` this docstring:
Do something with os.environ[FUNC_DEFAULT].
'''
func.__doc__ = func.__doc__.format(**sys.modules[func.__module__].__dict__)
return func
I've stuffed it into my cs.deco PyPI package for reuse.
