New submission from Barry A. Warsaw:
This is probably terrible, but given how difficult it is to keep __all__'s up
to date, maybe something like this can be useful. I literally whipped this up
in about 5 minutes, so sit back and watch the bikeshedding!
import sys
def public(thing):
if isinstance(thing, str):
mdict = sys._getframe(1).f_globals
name = thing
else:
mdict = sys.modules[thing.__module__].__dict__
name = thing.__name__
dunder_all = mdict.setdefault('__all__', [])
dunder_all.append(name)
return thing
Then:
@public
def baz(a, b):
return a + b
@public
def buz(c, d):
return c / d
def qux(e, f):
return e * f
class zup:
pass
@public
class zap:
pass
public('CONST1')
CONST1 = 3
CONST2 = 4
public('CONST3')
CONST3 = 5
Normally for any callable with an __name__, you can just decorate it with
@public to add it to __all__. Of course that doesn't worth with things like
constants, thus the str argument. But of course that also requires
sys._getframe() so blech.
