 +
 +IPython -- An enhanced Interactive Python
 +=========================================
 +
 +IPython offers a fully compatible replacement for the standard Python
 +interpreter, with convenient shell features, special commands, command
 +history mechanism and output results caching.
 +
 +At your system command line, type 'ipython -h' to see the command line
 +options available. This document only describes interactive features.
 +
 +GETTING HELP
 +------------
 +
 +Within IPython you have various way to access help:
 +
 +  ?         -> Introduction and overview of IPython's features (this screen).
 +  object?   -> Details about 'object'.
 +  object??  -> More detailed, verbose information about 'object'.
 +  %quickref -> Quick reference of all IPython specific syntax and magics.
 +  help      -> Access Python's own help system.
 +
 +If you are in terminal IPython you can quit this screen by pressing `q`.
 +
 +
 +MAIN FEATURES
 +-------------
 +
 +* Access to the standard Python help with object docstrings and the Python
 +  manuals. Simply type 'help' (no quotes) to invoke it.
 +
 +* Magic commands: type %magic for information on the magic subsystem.
 +
 +* System command aliases, via the %alias command or the configuration file(s).
 +
 +* Dynamic object information:
 +
 +  Typing ?word or word? prints detailed information about an object. Certain
 +  long strings (code, etc.) get snipped in the center for brevity.
 +
 +  Typing ??word or word?? gives access to the full information without
 +  snipping long strings. Strings that are longer than the screen are printed
 +  through the less pager.
 +
 +  The ?/?? system gives access to the full source code for any object (if
 +  available), shows function prototypes and other useful information.
 +
 +  If you just want to see an object's docstring, type '%pdoc object' (without
 +  quotes, and without % if you have automagic on).
 +
 +* Tab completion in the local namespace:
 +
 +  At any time, hitting tab will complete any available python commands or
 +  variable names, and show you a list of the possible completions if there's
 +  no unambiguous one. It will also complete filenames in the current directory.
 +
 +* Search previous command history in multiple ways:
 +
 +  - Start typing, and then use arrow keys up/down or (Ctrl-p/Ctrl-n) to search
 +    through the history items that match what you've typed so far.
 +
 +  - Hit Ctrl-r: opens a search prompt. Begin typing and the system searches
 +    your history for lines that match what you've typed so far, completing as
 +    much as it can.
 +
 +  - %hist: search history by index.
 +
 +* Persistent command history across sessions.
 +
 +* Logging of input with the ability to save and restore a working session.
 +
 +* System shell with !. Typing !ls will run 'ls' in the current directory.
 +
 +* The reload command does a 'deep' reload of a module: changes made to the
 +  module since you imported will actually be available without having to exit.
 +
 +* Verbose and colored exception traceback printouts. See the magic xmode and
 +  xcolor functions for details (just type %magic).
 +
 +* Input caching system:
 +
 +  IPython offers numbered prompts (In/Out) with input and output caching. All
 +  input is saved and can be retrieved as variables (besides the usual arrow
 +  key recall).
 +
 +  The following GLOBAL variables always exist (so don't overwrite them!):
 +  _i: stores previous input.
 +  _ii: next previous.
 +  _iii: next-next previous.
 +  _ih : a list of all input _ih[n] is the input from line n.
 +
 +  Additionally, global variables named _i<n> are dynamically created (<n>
 +  being the prompt counter), such that _i<n> == _ih[<n>]
 +
 +  For example, what you typed at prompt 14 is available as _i14 and _ih[14].
 +
 +  You can create macros which contain multiple input lines from this history,
 +  for later re-execution, with the %macro function.
 +
 +  The history function %hist allows you to see any part of your input history
 +  by printing a range of the _i variables. Note that inputs which contain
 +  magic functions (%) appear in the history with a prepended comment. This is
 +  because they aren't really valid Python code, so you can't exec them.
 +
 +* Output caching system:
 +
 +  For output that is returned from actions, a system similar to the input
 +  cache exists but using _ instead of _i. Only actions that produce a result
 +  (NOT assignments, for example) are cached. If you are familiar with
 +  Mathematica, IPython's _ variables behave exactly like Mathematica's %
 +  variables.
 +
 +  The following GLOBAL variables always exist (so don't overwrite them!):
 +  _ (one underscore): previous output.
 +  __ (two underscores): next previous.
 +  ___ (three underscores): next-next previous.
 +
 +  Global variables named _<n> are dynamically created (<n> being the prompt
 +  counter), such that the result of output <n> is always available as _<n>.
 +
 +  Finally, a global dictionary named _oh exists with entries for all lines
 +  which generated output.
 +
 +* Directory history:
 +
 +  Your history of visited directories is kept in the global list _dh, and the
 +  magic %cd command can be used to go to any entry in that list.
 +
 +* Auto-parentheses and auto-quotes (adapted from Nathan Gray's LazyPython)
 +
 +  1. Auto-parentheses
 +
 +     Callable objects (i.e. functions, methods, etc) can be invoked like
 +     this (notice the commas between the arguments)::
 +
 +         In [1]: callable_ob arg1, arg2, arg3
 +
 +     and the input will be translated to this::
 +
 +         callable_ob(arg1, arg2, arg3)
 +
 +     This feature is off by default (in rare cases it can produce
 +     undesirable side-effects), but you can activate it at the command-line
 +     by starting IPython with `--autocall 1`, set it permanently in your
 +     configuration file, or turn on at runtime with `%autocall 1`.
 +
 +     You can force auto-parentheses by using '/' as the first character
 +     of a line.  For example::
 +
 +          In [1]: /globals             # becomes 'globals()'
 +
 +     Note that the '/' MUST be the first character on the line!  This
 +     won't work::
 +
 +          In [2]: print /globals    # syntax error
 +
 +     In most cases the automatic algorithm should work, so you should
 +     rarely need to explicitly invoke /. One notable exception is if you
 +     are trying to call a function with a list of tuples as arguments (the
 +     parenthesis will confuse IPython)::
 +
 +          In [1]: zip (1,2,3),(4,5,6)  # won't work
 +
 +     but this will work::
 +
 +          In [2]: /zip (1,2,3),(4,5,6)
 +          ------> zip ((1,2,3),(4,5,6))
 +          Out[2]= [(1, 4), (2, 5), (3, 6)]
 +
 +     IPython tells you that it has altered your command line by
 +     displaying the new command line preceded by -->.  e.g.::
 +
 +          In [18]: callable list
 +          -------> callable (list)
 +
 +  2. Auto-Quoting
 +
 +     You can force auto-quoting of a function's arguments by using ',' as
 +     the first character of a line.  For example::
 +
 +          In [1]: ,my_function /home/me   # becomes my_function("/home/me")
 +
 +     If you use ';' instead, the whole argument is quoted as a single
 +     string (while ',' splits on whitespace)::
 +
 +          In [2]: ,my_function a b c   # becomes my_function("a","b","c")
 +          In [3]: ;my_function a b c   # becomes my_function("a b c")
 +
 +     Note that the ',' MUST be the first character on the line!  This
 +     won't work::
 +
 +          In [4]: x = ,my_function /home/me    # syntax error
 +
