Implementation of configuration-related magic functions.
This magic exposes most of the IPython config system. Any Configurable class should be able to be configured with the simple line:
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 : %config Available objects for config: TerminalInteractiveShell HistoryManager PrefilterManager AliasManager IPCompleter PromptManager DisplayFormatter
To view what is configurable on a given class, just pass the class name:
In : %config IPCompleter IPCompleter options ----------------- IPCompleter.omit__names=<Enum> 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. IPCompleter.merge_completions=<CBool> 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. IPCompleter.limit_to__all__=<CBool> 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 IPCompleter.greedy=<CBool> 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 : %config IPCompleter.greedy = True
and these values are read from the user_ns if they are variables:
In : feeling_greedy=False In : %config IPCompleter.greedy = feeling_greedy
