How to use %history and %recall in IPython.

ipython-history-recall-demo.txt

In [12]: %history?
Docstring:
::

  %history [-n] [-o] [-p] [-t] [-f FILENAME] [-g [PATTERN [PATTERN ...]]]
               [-l [LIMIT]] [-u]
               [range [range ...]]

Print input history (_i<n> variables), with most recent last.

By default, input history is printed without line numbers so it can be
directly pasted into an editor. Use -n to show them.

By default, all input history from the current session is displayed.
Ranges of history can be indicated using the syntax:

``4``
    Line 4, current session
``4-6``
    Lines 4-6, current session
``243/1-5``
    Lines 1-5, session 243
``~2/7``
    Line 7, session 2 before current
``~8/1-~6/5``
    From the first line of 8 sessions ago, to the fifth line of 6
    sessions ago.

Multiple ranges can be entered, separated by spaces

The same syntax is used by %macro, %save, %edit, %rerun

Examples
--------
::

  In [6]: %history -n 4-6
  4:a = 12
  5:print a**2
  6:%history -n 4-6

positional arguments:
  range

optional arguments:
  -n                    print line numbers for each input. This feature is
                        only available if numbered prompts are in use.
  -o                    also print outputs for each input.
  -p                    print classic '>>>' python prompts before each input.
                        This is useful for making documentation, and in
                        conjunction with -o, for producing doctest-ready
                        output.
  -t                    print the 'translated' history, as IPython understands
                        it. IPython filters your input and converts it all
                        into valid Python source before executing it (things
                        like magics or aliases are turned into function calls,
                        for example). With this option, you'll see the native
                        history instead of the user-entered version: '%cd /'
                        will be seen as 'get_ipython().magic("%cd /")' instead
                        of '%cd /'.
  -f FILENAME           FILENAME: instead of printing the output to the
                        screen, redirect it to the given file. The file is
                        always overwritten, though *when it can*, IPython asks
                        for confirmation first. In particular, running the
                        command 'history -f FILENAME' from the IPython
                        Notebook interface will replace FILENAME even if it
                        already exists *without* confirmation.
  -g <[PATTERN [PATTERN ...]]>
                        treat the arg as a glob pattern to search for in
                        (full) history. This includes the saved history
                        (almost all commands ever written). The pattern may
                        contain '?' to match one unknown character and '*' to
                        match any number of unknown characters. Use '%hist -g'
                        to show full saved history (may be very long).
  -l <[LIMIT]>          get the last n lines from all sessions. Specify n as a
                        single arg, or the default is the last 10 lines.
  -u                    when searching history using `-g`, show only unique
                        history.

In [14]: %recall?
Docstring:
Repeat a command, or get command to input line for editing.

%recall and %rep are equivalent.

- %recall (no arguments):

Place a string version of last computation result (stored in the
special '_' variable) to the next input prompt. Allows you to create
elaborate command lines without using copy-paste::

     In[1]: l = ["hei", "vaan"]
     In[2]: "".join(l)
    Out[2]: heivaan
     In[3]: %recall
     In[4]: heivaan_ <== cursor blinking

%recall 45

Place history line 45 on the next input prompt. Use %hist to find
out the number.

%recall 1-4

Combine the specified lines into one cell, and place it on the next
input prompt. See %history for the slice syntax.

%recall foo+bar

If foo+bar can be evaluated in the user namespace, the result is
placed at the next input prompt. Otherwise, the history is searched
for lines which contain that substring, and the most recent one is
placed at the next input prompt.
