22 print classic '>>>' python prompts before each input.
23 This is useful for making documentation, and in conjunction
24 with -o, for producing doctest-ready output.
25 z-t�raw� store_falseTa�
26 print the 'translated' history, as IPython understands it.
27 IPython filters your input and converts it all into valid Python
28 source before executing it (things like magics or aliases are turned
29 into function calls, for example). With this option, you'll see the
30 native history instead of the user-entered version: '%%cd /' will be
31 seen as 'get_ipython().run_line_magic("cd", "/")' instead of '%%cd /'.
32 z-f�filenamea�
33 FILENAME: instead of printing the output to the screen, redirect
34 it to the given file. The file is always overwritten, though *when
35 it can*, IPython asks for confirmation first. In particular, running
36 the command 'history -f FILENAME' from the IPython Notebook
37 interface will replace FILENAME even if it already exists *without*
38 confirmation.
39 )r r z-g�pattern�*Nac
40 treat the arg as a glob pattern to search for in (full) history.
41 This includes the saved history (almost all commands ever written).
42 The pattern may contain '?' to match one unknown character and '*'
43 to match any number of unknown characters. Use '%%hist -g' to show
44 full saved history (may be very long).
45 )r �nargsr r z-l�limit�?z�
46 get the last n lines from all sessions. Specify n as a single
47 arg, or the default is the last 10 lines.
48 )r �typer r r z-u�uniquezN

64
65 By default, input history is printed without line numbers so it can be
66 directly pasted into an editor. Use -n to show them.
67
68 By default, all input history from the current session is displayed.
69 Ranges of history can be indicated using the syntax:
70
71 ``4``
72 Line 4, current session
73 ``4-6``
74 Lines 4-6, current session
75 ``243/1-5``
76 Lines 1-5, session 243
77 ``~2/7``
78 Line 7, session 2 before current
79 ``~8/1-~6/5``
80 From the first line of 8 sessions ago, to the fifth line of 6
81 sessions ago.
82
83 Multiple ranges can be entered, separated by spaces
84
85 The same syntax is used by %macro, %save, %edit, %rerun

113 %recall and %rep are equivalent.
114
115 - %recall (no arguments):
116
117 Place a string version of last computation result (stored in the
118 special '_' variable) to the next input prompt. Allows you to create
119 elaborate command lines without using copy-paste::
120
121 In[1]: l = ["hei", "vaan"]
122 In[2]: "".join(l)
123 Out[2]: heivaan
124 In[3]: %recall
125 In[4]: heivaan_ <== cursor blinking
126
127 %recall 45
128
129 Place history line 45 on the next input prompt. Use %hist to find
130 out the number.
131
132 %recall 1-4
133
134 Combine the specified lines into one cell, and place it on the next
135 input prompt. See %history for the slice syntax.
136
137 %recall foo+bar
138
139 If foo+bar can be evaluated in the user namespace, the result is
140 placed at the next input prompt. Otherwise, the history is searched
141 for lines which contain that substring, and the most recent one is
142 placed at the next input prompt.

151
152 By default, you can specify ranges of input history to be repeated
153 (as with %history). With no arguments, it will repeat the last line.
154
155 Options:
156
157 -l <n> : Repeat the last n lines of input, not including the
158 current command.
159
160 -g foo : Repeat the most recent line which contains foo
