  Path to an extra config file to load.

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

BaseIPythonApplication.ipython_dir : Unicode

  Default: `u''`

  The name of the IPython directory. This directory is used for logging configuration (through profiles), history storage, etc. The default is usually $HOME/.ipython. This option can also be specified through the environment variable IPYTHONDIR.

  Default: `u'default'`

  The IPython profile to use.

BaseIPythonApplication.verbose_crash : Bool

  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.

InteractiveShell.automagic : CBool

  Default: `True`

  Enable magic commands to be called without the leading %.

InteractiveShell.banner1 : Unicode

  Default: `'Python 2.7.11 (default, Feb 25 2016, 11:43:03) \\nType "copyr...`

  The part of the banner to be printed before the profile

InteractiveShell.banner2 : Unicode

  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

  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.

InteractiveShell.multiline_history : CBool

  Default: `True`

  Save multi-line entries as one entry in readline history

InteractiveShell.object_info_string_level : 0|1|2

  Deprecated, use PromptManager.in2_template

InteractiveShell.prompt_out : Unicode

  Default: `'Out[\\#]: '`

  Deprecated, use PromptManager.out_template

InteractiveShell.prompts_pad_left : CBool

  Default: `True`

  No description

InteractiveShell.readline_parse_and_bind : List

  Default: `traitlets.Undefined`

InteractiveShell.readline_remove_delims : Unicode

  Default: `'-/~'`

  No description

InteractiveShell.readline_use : CBool

  Default: `True`

  No description

InteractiveShell.separate_in : SeparateUnicode

  Default: `'\\n'`

  No description

InteractiveShell.separate_out : SeparateUnicode

InteractiveShell.wildcards_case_sensitive : CBool

  Default: `True`

  No description

InteractiveShell.xmode : ‘Context’|’Plain’|’Verbose’

  Default: `'Context'`

  No description

TerminalInteractiveShell.autoedit_syntax : CBool

  Default: `False`

  auto editing of files with syntax errors.

TerminalInteractiveShell.confirm_exit : CBool

  Default: `True`

  Set to confirm when you try to exit IPython with an EOF (Control-D in Unix, Control-Z/Enter in Windows). By typing ‘exit’ or ‘quit’, you can force a direct exit without any confirmation.

TerminalInteractiveShell.editor : Unicode

  Default: `'vi'`

  Set the editor used by IPython (default to $EDITOR/vi/notepad).

TerminalInteractiveShell.pager : Unicode

  Default: `'less'`

  The shell program to be used for paging.

TerminalInteractiveShell.screen_length : Integer

  Default: `0`

  Number of lines of your screen, used to control printing of very long strings. Strings longer than this number of lines will be sent through a pager instead of directly printed. The default value for this is 0, which means IPython will auto-detect your screen size every time it needs to print certain potentially long strings (this doesn’t change the behavior of the ‘print’ keyword, it’s only triggered internally). If for some reason this isn’t working well (it needs curses support), specify it yourself. Otherwise don’t change the default.

TerminalInteractiveShell.term_title : CBool

  Default: `False`

  Enable auto setting the terminal title.

PromptManager.color_scheme : Unicode

  Default: `'Linux'`

  No description

PromptManager.in2_template : Unicode

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

  Continuation prompt.

PromptManager.in_template : Unicode

  Default: `'In [\\#]: '`

  Input prompt. ‘#’ will be transformed to the prompt number

PromptManager.justify : Bool

  Default: `True`

  If True (default), each prompt will be right-aligned with the preceding one.

PromptManager.out_template : Unicode

  Default: `'Out[\\#]: '`

  Output prompt. ‘#’ will be transformed to the prompt number

HistoryAccessor.connection_options : Dict

  Default: `traitlets.Undefined`

  Options for configuring the SQLite connection

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

HistoryAccessor.enabled : Bool

  Default: `True`

  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.

HistoryAccessor.hist_file : Unicode

  Default: `u''`

  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

HistoryManager.db_cache_size : Integer

  Default: `0`

  Write to database every x commands (higher values save disk access & power). Values of 1 or less effectively disable caching.

HistoryManager.db_log_output : Bool

  Default: `False`

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

ProfileDir.location : Unicode

  Default: `u''`

  Set the profile location directly. This overrides the logic used by the `profile` option.

BaseFormatter.deferred_printers : Dict

  Default: `traitlets.Undefined`

  No description

BaseFormatter.enabled : Bool

  Default: `True`

  No description

BaseFormatter.singleton_printers : Dict

  Truncate large collections (lists, dicts, tuples, sets) to this size.

  Set to 0 to disable truncation.

PlainTextFormatter.max_width : Integer

  Default: `79`

  No description

PlainTextFormatter.newline : Unicode

  Default: `'\\n'`

  No description

PlainTextFormatter.pprint : Bool

  Default: `True`

  No description

PlainTextFormatter.verbose : Bool

  Default: `False`

  No description

Completer.greedy : CBool

  Default: `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.

IPCompleter.limit_to__all__ : CBool

  Default: `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.merge_completions : CBool

  Default: `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.omit__names : 0|1|2

  Default: `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.

ScriptMagics.script_magics : List

  Default: `traitlets.Undefined`

  Extra script cell magics to define

  This generates simple wrappers of `%%script foo` as `%%foo`.

  If you want to add script magics that aren’t on your path, specify them in script_paths

ScriptMagics.script_paths : Dict

  Default: `traitlets.Undefined`

  Dict mapping short ‘ruby’ names to full paths, such as ‘/opt/secret/bin/ruby’

  Only necessary for items in script_magics where the default path will not find the right interpreter.

StoreMagics.autorestore : Bool

  Default: `False`

  If True, any %store-d variables will be automatically restored when IPython starts.
