# Module: `core.magics.auto`

Implementation of magic functions that control various automatic behaviors.

## 1 Class

class `IPython.core.magics.auto.` `AutoMagics`(shell)

  Bases: `IPython.core.magic.Magics`

  Magics that control various autoX behaviors.

  `__init__`(shell)
  `autocall`(parameter_s='')

    Make functions callable without having to type parentheses.

    Usage:

    > %autocall [mode]

    The mode can be one of: 0->Off, 1->Smart, 2->Full. If not given, the value is toggled on and off (remembering the previous state).

    In more detail, these values mean:

    0 -> fully disabled

    1 -> active, but do not apply if there are no arguments on the line.

    In this mode, you get:

        In [1]: callable
        Out[1]: <built-in function callable>

        In [2]: callable 'hello'
        ------> callable('hello')
        Out[2]: False

    2 -> Active always. Even if no arguments are present, the callable object is called:

        In [2]: float
        ------> float()
        Out[2]: 0.0

    Note that even with autocall off, you can still use ‘/’ at the start of a line to treat the first argument on the command line as a function and add parentheses to it:

        In [8]: /str 43
        ------> str(43)
        Out[8]: '43'

    # all-random (note for auto-testing)

  `automagic`(parameter_s='')

    Make magic functions callable without having to type the initial %.

    Without argumentsl toggles on/off (when off, you must call it as %automagic, of course). With arguments it sets the value, and you can use any of (case insensitive):

    > - on, 1, True: to activate
    > - off, 0, False: to deactivate.

    Note that magic functions have lowest priority, so if there’s a variable whose name collides with that of a magic fn, automagic won’t work for that function (you get the variable instead). However, if you delete the variable (del var), the previously shadowed magic function becomes visible to automagic again.
