IPython kernel options
======================

These options can be used in :file:`ipython_kernel_config.py`. The kernel also respects any options in `ipython_config.py`



ConnectionFileMixin.connection_file : Unicode
    Default: ``''``

    JSON file in which to store connection info [default: kernel-<pid>.json]
    
    This file will contain the IP, ports, and authentication key needed to connect
    clients to this kernel. By default, this file will be created in the security dir
    of the current profile, but can be specified by absolute path.


ConnectionFileMixin.control_port : Integer
    Default: ``0``

    set the control (ROUTER) port [default: random]

    Default: ``0``

    set the iopub (PUB) port [default: random]

ConnectionFileMixin.ip : Unicode
    Default: ``u''``

    Set the kernel's IP address [default localhost].
    If the IP address is something other than localhost, then
    Consoles on other machines will be able to connect
    to the Kernel, so be careful!

ConnectionFileMixin.shell_port : Integer
    Default: ``0``

    set the shell (ROUTER) port [default: random]

ConnectionFileMixin.stdin_port : Integer
    Default: ``0``

    selecting a particular matplotlib backend and loop integration.


InteractiveShellApp.pylab_import_all : Bool
    Default: ``True``

    If true, IPython will populate the user namespace with numpy, pylab, etc.
    and an ``import *`` is done from numpy and pylab, when using pylab mode.
    
    When False, pylab mode should not import any names into the user namespace.

    Default: ``False``

    Whether to install the default config files into the profile dir.

    If specified, load this config file in addition to any other IPython config.

    The name of the IPython directory. This directory is used for logging
    configuration (through profiles), history storage, etc. The default

    'all', 'last', 'last_expr' or 'none', specifying which nodes should be
    run interactively (displaying output from expressions).

InteractiveShell.ast_transformers : List

    A list of ast.NodeTransformer subclass instances, which will be applied
    to user input before code is run.


InteractiveShell.autocall : 0|1|2
    Default: ``0``

    
    Make IPython automatically call any callable object even if you didn't
    type explicit parentheses. For example, 'str 43' becomes 'str(43)'
    automatically. The value can be '0' to disable the feature, '1' for
    'smart' autocall, where it is not applied if there are no more
    arguments on the line, and '2' for 'full' autocall, where all callable
    objects are automatically called (even if no arguments are present).


InteractiveShell.autoindent : CBool
    Default: ``True``

    
    Autoindent IPython code entered interactively.

    Default: ``''``

    The part of the banner to be printed after the profile

InteractiveShell.cache_size : Integer
    Default: ``1000``

    
    Set the size of the output cache.  The default is 1000, you can
    change it permanently in your config file.  Setting it to 0 completely
    disables the caching system, and the minimum value accepted is 20 (if
    you provide a value less than 20, it is reset to 0 and a warning is
    issued).  This limit is defined because otherwise you'll spend more
    time re-flushing a too small cache than working


InteractiveShell.color_info : CBool
    Default: ``True``

    
    Use colors for displaying information about objects. Because this
    information is passed through a pager (like 'less'), and some pagers
    get confused with color codes, this capability can be turned off.


InteractiveShell.colors : 'NoColor'|'LightBG'|'Linux'
    Default: ``'Linux'``

    Set the color scheme (NoColor, Linux, or LightBG).

InteractiveShell.debug : CBool
    Default: ``False``

    No description

InteractiveShell.deep_reload : CBool
    Default: ``False``

    
    **Deprecated**
    
    Enable deep (recursive) reloading by default. IPython can use the
    deep_reload module which reloads changes in modules recursively (it
    replaces the reload() function, so you don't need to change anything to
    use it). `deep_reload` forces a full reload of modules whose code may
    have changed, which the default reload() function does not.  When
    deep_reload is off, IPython will use the normal reload(), but
    deep_reload will still be available as dreload().


InteractiveShell.disable_failing_post_execute : CBool
    Default: ``False``

    Don't call post-execute functions that have failed in the past.

InteractiveShell.display_page : Bool
    Default: ``False``

    If True, anything that would be passed to the pager
    will be displayed as regular output instead.

InteractiveShell.history_length : Integer
    Default: ``10000``

    No description

InteractiveShell.history_load_length : Integer
    Default: ``1000``

    
    The number of saved history entries to be loaded
    into the readline buffer at startup.

    Default: ``''``

    No description

    Default: ``''``

    
    Start logging to the given file in append mode.
    Use `logfile` to specify a log file to **overwrite** logs to.


InteractiveShell.logfile : Unicode
    Default: ``''``

    
    The name of the logfile to use.


InteractiveShell.logstart : CBool
    Default: ``False``

    
    Start logging to the default log file in overwrite mode.
    Use `logappend` to specify a log file to **append** logs to.

    Default: ``'   .\\D.: '``

    Deprecated, use PromptManager.in2_template
