    IPython own testing machinery, and emacs inferior-shell integration through elpy.
    
    This mode default to `True` if the `IPY_TEST_SIMPLE_PROMPT`

.. configtrait:: HistoryAccessor.connection_options

    Options for configuring the SQLite connection
    
    These options are passed as keyword args to sqlite3.connect
    when establishing database conenctions.

    :trait type: Dict

.. configtrait:: 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``

.. configtrait:: 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: Unicode

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

    :trait type: Bool

.. configtrait:: HistoryManager.enabled

    set enabled=False to disable the SQLite history,

    threaded environments where IPython is embedded.

    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
