Cqd: Colour my __dir__ please

Pro-tip: put things like this in your ~/.pythonrc so that they're loaded when you start the REPL. I have a few things in mine, like configuring readline, a couple of functions to dump objects as JSON or YAML, and imports for pprint and datetime so that they're all there when I'm doing interactive stuff.

I love to see investment in tools like these, so thank you so much for working on it and packaging it.

Another useful tool that I don’t see cheered enough for is vars(). When integrating new api-s, you’d often find yourself at pdb(or ipdb) prompt pretty printing(pp) loaded variables and attributes calls - pp(vars(foo)) has been a great friend reducing the burden of dot walking.

One thing I have longed for, but never took the time to research though, is pagination - your debugger window is often fighting for screen real estate, so data rich API calls becomes a little jarring.

I found myself wanting a quick way to navigate dir() from the terminal. This is a tiny, simple python package that helps in this regard.

Is it just a coincidence that the name is https://en.wikipedia.org/wiki/CQD, the old SOS?

I think it would be a good idea to consider name-mangled attributes (https://docs.python.org/3/tutorial/classes.html#private-vari... ; https://stackoverflow.com/questions/7456807) separately:

    >>> class x:
    ...   def __foo(self): pass
    ... 
    >>> dir(x) # word-wrapped manually to protect your eyes
    ['__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__',
     '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__',
     '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__',
     '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__',
     '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__',
     '__weakref__', '_x__foo']

`__foo` is probably not meant for external use, but the real reason to use the leading double underscore is to invoke that name mangling and thus avoid name collisions in subclasses. Some people do still use this feature. (These days, I barely even use inheritance.)

Perhaps it could use the same colour for the `_x` as for other single-underscore names, and a fourth colour for the `__foo` part.
