Important

This documentation covers IPython versions 6.0 and higher. Beginning with version 6.0, IPython stopped supporting compatibility with Python versions lower than 3.3 including all versions of Python 2.7.

If you are looking for an IPython version compatible with Python 2.7, please use the IPython 5.x LTS release and refer to its documentation (LTS is the long term support release).

Application.logging_config

Configure additional log handlers.

The default stderr logs handler is configured by the log_level, log_datefmt and log_format settings.

This configuration can be used to configure additional handlers (e.g. to output the log to a file) or for finer control over the default handlers.

If provided this should be a logging configuration dictionary, for more information see: https://docs.python.org/3/library/logging.config.html#logging-config-dictschema

This dictionary is merged with the base logging configuration which defines the following:

  • A logging formatter intended for interactive use called console.

  • A logging handler that writes to stderr called console which uses the formatter console.

  • A logger with the name of this application set to DEBUG level.

This example adds a new handler that writes to a file:

c.Application.logging_config = {
    "handlers": {
        "file": {
            "class": "logging.FileHandler",

TerminalInteractiveShell.shortcuts

  • match_filter: shortcut filter used to match an existing shortcut,

  • new_keys: list of keys to set,

  • new_filter: a new shortcut filter to set

The filters have to be composed of pre-defined verbs and joined by one of the following conjunctions: & (and), | (or), ~ (not). The pre-defined verbs are:

  • always

  • never

  • has_line_below

  • has_line_above

  • is_cursor_at_the_end_of_line

  • has_selection

  • has_suggestion

To disable a shortcut set new_keys to an empty list. To add a shortcut add key create with value True.

When modifying/disabling shortcuts, match_keys/match_filter can be omitted if the provided specification uniquely identifies a shortcut to be modified/disabled. When modifying a shortcut new_filter or new_keys can be omitted which will result in reuse of the existing filter/keys.

Only shortcuts defined in IPython (and not default prompt-toolkit shortcuts) can be modified or disabled. The full list of shortcuts, command identifiers and filters is available under IPython shortcuts.

HistoryAccessor.connection_options

Options for configuring the SQLite connection

These options are passed as keyword args to sqlite3.connect when establishing database connections.

Trait type:

Dict

HistoryAccessor.enabled

enable the SQLite history

set enabled=False to disable the SQLite history, in which case there will be no stored history, no SQLite connection, and no background saving thread. This may be necessary in some threaded environments where IPython is embedded.

Trait type:

Bool

Default:

True

HistoryAccessor.hist_file

Path to file to use for SQLite history database.

By default, IPython will put the history database in the IPython profile directory. If you would rather share one history among profiles, you can set this value in each, so that they are consistent.

Due to an issue with fcntl, SQLite is known to misbehave on some NFS mounts. If you see IPython hanging, try setting this to something on a local disk, e.g:

ipython --HistoryManager.hist_file=/tmp/ipython_hist.sqlite

you can also use the specific value :memory: (including the colon at both end but not the back ticks), to avoid creating an history file.

Trait type:

Union

HistoryManager.connection_options

Options for configuring the SQLite connection

These options are passed as keyword args to sqlite3.connect when establishing database connections.

Trait type:

HistoryManager.db_cache_size

Trait type:

Int

Default:

0

HistoryManager.db_log_output

Should the history database include output? (default: no)

Trait type:

Bool

Default:

False

HistoryManager.enabled

enable the SQLite history

set enabled=False to disable the SQLite history, in which case there will be no stored history, no SQLite connection, and no background saving thread. This may be necessary in some threaded environments where IPython is embedded.

Trait type:

Union

MagicsManager.auto_magic

Automatically call line magics without requiring explicit % prefix

Trait type:

Bool

Default:

True

MagicsManager.lazy_magics

Mapping from magic names to modules to load.

This can be used in IPython/IPykernel configuration to declare lazy magics that will only be imported/registered on first use.

For example:

c.MagicsManager.lazy_magics = {
  "my_magic": "slow.to.import",
  "my_other_magic": "also.slow",
}

On first invocation of %my_magic, %%my_magic, %%my_other_magic or %%my_other_magic, the corresponding module will be loaded as an ipython extensions as if you had previously done %load_ext ipython.

Magics names should be without percent(s) as magics can be both cell and line magics.

Lazy loading happen relatively late in execution process, and complex extensions that manipulate Python/IPython internal state or global state might not support lazy loading.

Completer.auto_close_dict_keys

Enable auto-closing dictionary keys.

Trait type:

Bool

Default:

False

Completer.evaluation

Policy for code evaluation under completion.

Successive options allow to enable more eager evaluation for better completion suggestions, including for nested dictionaries, nested lists, or even results of function calls. Setting unsafe or higher can lead to evaluation of arbitrary user code on Tab with potentially unwanted or dangerous side effects.

Allowed values are:

  • forbidden: no evaluation of code is permitted,

  • minimal: evaluation of literals and access to built-in namespace; no item/attribute evaluationm no access to locals/globals, no evaluation of any operations or comparisons.

  • limited: access to all namespaces, evaluation of hard-coded methods (for example: dict.keys, object.__getattr__, object.__getitem__) on allow-listed objects (for example: dict, list, tuple, pandas.Series),

  • unsafe: evaluation of all methods and function calls but not of syntax with side-effects like del x,

  • dangerous: completely arbitrary evaluation.

Options:

'forbidden', 'minimal', 'limited', 'unsafe', 'dangerous'

Default:

'limited'

Trait type:

Int

Default:

400

IPCompleter.limit_to__all__

DEPRECATED as of version 5.0.

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

Trait type:

Bool

Default:

False

IPCompleter.merge_completions

Whether to merge completion results into a single list

If False, only the completion results from the first non-empty completer will be returned.

As of version 8.6.0, setting the value to False is an alias for: IPCompleter.suppress_competing_matchers = True..

Trait type:

Bool

Default:

True

IPCompleter.omit__names

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 0: nothing will be excluded.

If True, emit profiling data for completion subsystem using cProfile.

Trait type:

Bool

Default:

False

IPCompleter.profiler_output_dir

Template for path at which to output profile data for completions.

Trait type:

Unicode

Default:

'.completion_profiles'

IPCompleter.suppress_competing_matchers

Whether to suppress completions from other Matchers.

When set to None (default) the matchers will attempt to auto-detect whether suppression of other matchers is desirable. For example, at the beginning of a line followed by % we expect a magic completion to be the only applicable option, and after my_dict[' we usually expect a completion with an existing dictionary key.

If you want to disable this heuristic and see completions from all matchers, set IPCompleter.suppress_competing_matchers = False. To disable the heuristic for specific matchers provide a dictionary mapping: IPCompleter.suppress_competing_matchers = {'IPCompleter.dict_key_matcher': False}.

Set IPCompleter.suppress_competing_matchers = True to limit completions to the set of matchers with the highest priority; this is equivalent to IPCompleter.merge_completions and can be beneficial for performance, but will sometimes omit relevant candidates from matchers further down the priority list.
