| malinoff | Hi, is there a simple way to inherit docstrings defined in the implemted interface? | 11:04 |
|---|---|---|
| mgedmin | not that I'm aware of | 11:05 |
| mgedmin | some documentation generation tools can pay attention to zope interfaces (pydoctor, iirc?) | 11:06 |
| mgedmin | it ought to be possible to write a class decorator for adding the missing docstrings | 11:06 |
| mgedmin | or a Sphinx extension | 11:06 |
| mgedmin | hm, google tells me Sphinx extensions for zope interfaces already exist | 11:07 |
| mgedmin | I don't know if they do what you want them to do | 11:07 |
| mgedmin | I don't know what exactly you want to happen and when :) | 11:07 |
| malinoff | mgedmin, i always work within ipython (and i suggest that most of experienced pythonistas use it), and i want to cut the following sequence: obj.meth? -> q -> find interface defines meth (the most horrible part) -> IMeth.meth? just to obj.meth? | 11:09 |
| mgedmin | sounds like a good idea | 11:09 |
| mgedmin | I see two solutions: the aforementioned class decorator (which would imply changing all the code that uses interfaces) | 11:09 |
| mgedmin | or an ipython plugin | 11:09 |
| malinoff | I just found myself to repeat this stuff over and over again, so the question pops out | 11:10 |
| mgedmin | actually, maybe zope.interface could add __doc__ on all the methods during class creation time? | 11:10 |
| mgedmin | feel free to suggest this feature at https://github.com/zopefoundation/zope.interface/issues | 11:10 |
| mgedmin | but I don't think it will happen unless you write a patch (with tests) | 11:11 |
| malinoff | mgedmin, thanks, I won't suggest this to zope.inteface for now, because I can't imagine a simple way to deal with multiple inheritance. I think i'll just go with a decorator | 11:21 |
| malinoff | but i'll keep that in my mind | 11:22 |
| mgedmin | does ipython deal with inheritance? i.e. overridden methods that have no docstrings, do you get to see the docstring from the base class version of the method? | 11:22 |
| malinoff | If i override a method defined in a base class, no, I won't see the base class' method docstring | 11:24 |
| mgedmin | seems like it'd create the same kind of inconvenience | 11:24 |
| mgedmin | and maybe could be fixed in the same way you intend to fix docstring inheritance from interfaces | 11:25 |
| malinoff | alright, this http://stackoverflow.com/questions/8100166/inheriting-methods-docstrings-in-python seems to work | 11:27 |
| malinoff | with one small fix to inspect __implemented__ instead of __bases__ | 11:28 |
| mgedmin | I'd use API instead of touching the __special__ attributes directly | 11:30 |
| mgedmin | zope.interface.implementedBy(cls), IIRC | 11:30 |
| mgedmin | but whatever works :) | 11:30 |
| malinoff | sure, i just outlined the general approach | 11:30 |
| malinoff | mgedmin, thanks - I think one simple class decorator is actually ok | 11:31 |

| malinoff | Alright, made it work. If someone curious about it, here is the whole code: http://pastie.org/private/rwp4axznidjhrqe63dfg | 12:31 |
| malinoff | Oh god it saves so much lines of code | 12:37 |
| malinoff | errr | 13:10 |

| mgedmin | malinoff, I wonder if http://docs.zope.org/zope.interface/api.html#ISpecification.__iro__ wouldn't be useful for you there | 14:05 |

| malinoff | mgedmin, that's what i wanted :) thank you | 14:22 |
| malinoff | was confused a bit when obj.__mro__ threw AttributeError | 14:23 |
| malinoff | yep, all tests pass | 14:24 |
| malinoff | btw, zope.interface is awesome, it's soo easy to work with | 14:27 |
