Module: core.magics.config

Implementation of configuration-related magic functions.

1 Class

class IPython.core.magics.config.ConfigMagics(shell)

Bases: IPython.core.magic.Magics


configure IPython

%config Class[.trait=value]

This magic exposes most of the IPython config system. Any Configurable class should be able to be configured with the simple line:

%config Class.trait=value

Where value will be resolved in the user’s namespace, if it is an expression or variable name.


To see what classes are available for config, pass no arguments:

In [1]: %config
Available objects for config:

To view what is configurable on a given class, just pass the class name:

In [2]: %config IPCompleter
IPCompleter options
    Current: 2
    Choices: (0, 1, 2)
    Instruct the completer to omit private method names
    Specifically, when completing on ``object.<tab>``.
    When 2 [default]: all names that start with '_' will be excluded.
    When 1: all 'magic' names (``__foo__``) will be excluded.
    When 0: nothing will be excluded.
    Current: True
    Whether to merge completion results into a single list
    If False, only the completion results from the first non-empty
    completer will be returned.
    Current: False
    Instruct the completer to use __all__ for the completion
    Specifically, when completing on ``object.<tab>``.
    When True: only those names in obj.__all__ will be included.
    When False [default]: the __all__ attribute is ignored
    Current: False
    Activate greedy completion
    This will enable completion on elements of lists, results of
    function calls, etc., but can be unsafe because the code is
    actually evaluated on TAB.

but the real use is in setting values:

In [3]: %config IPCompleter.greedy = True

and these values are read from the user_ns if they are variables:

In [4]: feeling_greedy=False

In [5]: %config IPCompleter.greedy = feeling_greedy
