Just an idea, would it be possible to have tab completion of functions' arguments names?



Min RK

Should be possible, I think. We would have to detect that we are inside a function call and identify that function, which I don't think we do, but presumably could.

Example, assuming you have found the function:

import inspect

spec = inspect.getargspec(func)
# only get names of keyword args:
if spec.defaults:
    kwargnames = spec.args[-len(spec.defaults):]

Having just tested, it seems we already can do that. I tried:

In [6]: def f(kinkajou=True):
   ...:     print kinkajou

In [7]: f(k

good call, it certainly does work. I probably should have checked :). Closing.

Yes, but the current behaviour seems to show only optional arguments,

def f(koala, kinkajou=True):
    print "I'm a koala"
kaiser kinkajou= kron

Why not get completion for all arguments?

You can actually, e.g.,

>>> def f(a, b):
...     print a, b

>>> f(a=3, b=4)
3 4

>>> f(b=3, a=4)
4 3

that's using Python 2.7, not sure about earlier versions.

Good call, I had forgotten about that! It does work in 2.6, which is the earliest version supported by IPython. How's this?
