88 The configuration of an application can be done via four different Config
89 objects, which are loaded and ultimately merged into a single one used from
90 that point on by the app. These are:
91
92 1. default_config: internal defaults, implemented in code.
93 2. file_config: read from the filesystem.
94 3. command_line_config: read from the system's command line flags.
95 4. constructor_config: passed parametrically to the constructor.

105 parametrically (e.g. in testing or sphinx plugins) objects with a known

285 similar to Context, but additionally prints the variables currently
286 visible where the exception happened (shortening their strings if too
287 long). This can potentially be very slow, if you happen to have a huge
288 data structure whose string representation is complex to compute.
289 Your computer may appear to freeze for a while with cpu usage at 100%%.
290 If this occurs, you can cancel the traceback with Ctrl-C (maybe hitting
291 it more than once).

13 IPython -- An enhanced Interactive Python
14 =========================================
15 cl_usage = """\
16 ipython [options] [files]
15 17
16 A Python shell with automatic history (input and output), dynamic object
17 introspection, easier configuration, command completion, access to the system
18 shell and more.
19
20 IPython can also be embedded in running programs. See EMBEDDING below.
21
22
23 USAGE
24 ipython [options] files
25
26 If invoked with no options, it executes all the files listed in
27 sequence and drops you into the interpreter while still acknowledging
28 any options you may have set in your ipythonrc file. This behavior is
29 different from standard Python, which when called as python -i will
30 only execute one file and will ignore your configuration setup.
31
32 Please note that some of the configuration options are not available at
33 the command line, simply because they are not practical here. Look into
34 your ipythonrc configuration file for details on those. This file
35 typically installed in the $HOME/.ipython directory.
36
37 For Windows users, $HOME resolves to C:\\Documents and
38 Settings\\YourUserName in most instances, and _ipython is used instead
39 of .ipython, since some Win32 programs have problems with dotted names
40 in directories.
41
42 In the rest of this text, we will refer to this directory as
43 IPYTHONDIR.
44
45 REGULAR OPTIONS
46 After the above threading options have been given, regular options can
47 follow in any order. All options can be abbreviated to their shortest
48 non-ambiguous form and are case-sensitive. One or two dashes can be
49 used. Some options have an alternate short form, indicated after a |.
50
51 Most options can also be set from your ipythonrc configuration file.
52 See the provided examples for assistance. Options given on the comman-
53 dline override the values set in the ipythonrc file.
54
55 All options with a [no] prepended can be specified in negated form
56 (using -nooption instead of -option) to turn the feature off.
57
58 -h, --help
59 Show summary of options.
60
61 -autocall <val>
62 Make IPython automatically call any callable object even if you
63 didn't type explicit parentheses. For example, 'str 43' becomes
64 'str(43)' automatically. The value can be '0' to disable the
65 feature, '1' for 'smart' autocall, where it is not applied if
66 there are no more arguments on the line, and '2' for 'full'
67 autocall, where all callable objects are automatically called
68 (even if no arguments are present). The default is '1'.
69
70 -[no]autoindent
71 Turn automatic indentation on/off.
72
73 -[no]automagic
74 Make magic commands automatic (without needing their first char-
75 acter to be %). Type %magic at the IPython prompt for more
76 information.
77
78 -[no]autoedit_syntax
79 When a syntax error occurs after editing a file, automatically
80 open the file to the trouble causing line for convenient fixing.
81
82 -[no]banner
83 Print the intial information banner (default on).
84
85 -c <command>
86 Execute the given command string, and set sys.argv to ['c'].
87 This is similar to the -c option in the normal Python inter-
88 preter.
89
90 -cache_size|cs <n>
91 Size of the output cache (maximum number of entries to hold in
92 memory). The default is 1000, you can change it permanently in
93 your config file. Setting it to 0 completely disables the
94 caching system, and the minimum value accepted is 20 (if you
95 provide a value less than 20, it is reset to 0 and a warning is
96 issued). This limit is defined because otherwise you'll spend
97 more time re-flushing a too small cache than working.
98
99 -classic|cl
100 Gives IPython a similar feel to the classic Python prompt.
101
102 -colors <scheme>
103 Color scheme for prompts and exception reporting. Currently
104 implemented: NoColor, Linux, and LightBG.
105
106 -[no]color_info
107 IPython can display information about objects via a set of func-
108 tions, and optionally can use colors for this, syntax highlight-
109 ing source code and various other elements. However, because
110 this information is passed through a pager (like 'less') and
111 many pagers get confused with color codes, this option is off by
112 default. You can test it and turn it on permanently in your
113 ipythonrc file if it works for you. As a reference, the 'less'
114 pager supplied with Mandrake 8.2 works ok, but that in RedHat
115 7.2 doesn't.
116
117 Test it and turn it on permanently if it works with your system.
118 The magic function @color_info allows you to toggle this inter-
119 actively for testing.
120
121 -[no]confirm_exit
122 Set to confirm when you try to exit IPython with an EOF (Con-
123 trol-D in Unix, Control-Z/Enter in Windows). Note that using the
124 magic functions @Exit or @Quit you can force a direct exit,
125 bypassing any confirmation.
126
127 -[no]debug
128 Show information about the loading process. Very useful to pin
129 down problems with your configuration files or to get details
130 about session restores.
131
132 -[no]deep_reload
133 IPython can use the deep_reload module which reloads changes in
134 modules recursively (it replaces the reload() function, so you
135 don't need to change anything to use it). deep_reload() forces a
136 full reload of modules whose code may have changed, which the
137 default reload() function does not.
138
139 When deep_reload is off, IPython will use the normal reload(),
140 but deep_reload will still be available as dreload(). This fea-
141 ture is off by default [which means that you have both normal
142 reload() and dreload()].
143
144 -editor <name>
145 Which editor to use with the @edit command. By default, IPython
146 will honor your EDITOR environment variable (if not set, vi is
147 the Unix default and notepad the Windows one). Since this editor
148 is invoked on the fly by IPython and is meant for editing small
149 code snippets, you may want to use a small, lightweight editor
150 here (in case your default EDITOR is something like Emacs).
151
152 -ipythondir <name>
153 The name of your IPython configuration directory IPYTHONDIR.
154 This can also be specified through the environment variable
155 IPYTHONDIR.
156
157 -log|l Generate a log file of all input. The file is named
158 ipython_log.py in your current directory (which prevents logs
159 from multiple IPython sessions from trampling each other). You
160 can use this to later restore a session by loading your logfile
161 as a file to be executed with option -logplay (see below).
162
163 -logfile|lf
164 Specify the name of your logfile.
165
166 -logplay|lp
167 Replay a previous log. For restoring a session as close as pos-
168 sible to the state you left it in, use this option (don't just
169 run the logfile). With -logplay, IPython will try to reconstruct
170 the previous working environment in full, not just execute the
171 commands in the logfile.
172 When a session is restored, logging is automatically turned on
173 again with the name of the logfile it was invoked with (it is
174 read from the log header). So once you've turned logging on for
175 a session, you can quit IPython and reload it as many times as
176 you want and it will continue to log its history and restore
177 from the beginning every time.
178
179 Caveats: there are limitations in this option. The history vari-
180 ables _i*,_* and _dh don't get restored properly. In the future
181 we will try to implement full session saving by writing and
182 retrieving a failed because of inherent limitations of Python's
183 Pickle module, so this may have to wait.
184
185 -[no]messages
186 Print messages which IPython collects about its startup process
187 (default on).
188
189 -[no]pdb
190 Automatically call the pdb debugger after every uncaught excep-
191 tion. If you are used to debugging using pdb, this puts you
192 automatically inside of it after any call (either in IPython or
193 in code called by it) which triggers an exception which goes
194 uncaught.
195
196 -[no]pprint
197 IPython can optionally use the pprint (pretty printer) module
198 for displaying results. pprint tends to give a nicer display of
199 nested data structures. If you like it, you can turn it on per-
200 manently in your config file (default off).
201
202 -profile|p <name>
203 Assume that your config file is ipythonrc-<name> (looks in cur-
204 rent dir first, then in IPYTHONDIR). This is a quick way to keep
205 and load multiple config files for different tasks, especially
206 if you use the include option of config files. You can keep a
207 basic IPYTHONDIR/ipythonrc file and then have other 'profiles'
208 which include this one and load extra things for particular
209 tasks. For example:
210
211 1) $HOME/.ipython/ipythonrc : load basic things you always want.
212 2) $HOME/.ipython/ipythonrc-math : load (1) and basic math-
213 related modules.
214 3) $HOME/.ipython/ipythonrc-numeric : load (1) and Numeric and
215 plotting modules.
216
217 Since it is possible to create an endless loop by having circu-
218 lar file inclusions, IPython will stop if it reaches 15 recur-
219 sive inclusions.
220
221 -prompt_in1|pi1 <string>
222 Specify the string used for input prompts. Note that if you are
223 using numbered prompts, the number is represented with a '\#' in
224 the string. Don't forget to quote strings with spaces embedded
225 in them. Default: 'In [\#]: '.
226
227 Most bash-like escapes can be used to customize IPython's
228 prompts, as well as a few additional ones which are IPython-spe-
229 cific. All valid prompt escapes are described in detail in the
230 Customization section of the IPython HTML/PDF manual.
231
232 -prompt_in2|pi2 <string>
233 Similar to the previous option, but used for the continuation
234 prompts. The special sequence '\D' is similar to '\#', but with
235 all digits replaced dots (so you can have your continuation
236 prompt aligned with your input prompt). Default: ' .\D.: '
237 (note three spaces at the start for alignment with 'In [\#]').
238
239 -prompt_out|po <string>
240 String used for output prompts, also uses numbers like
241 prompt_in1. Default: 'Out[\#]:'.
242
243 -quick Start in bare bones mode (no config file loaded).
244
245 -rcfile <name>
246 Name of your IPython resource configuration file. normally
247 IPython loads ipythonrc (from current directory) or
248 IPYTHONDIR/ipythonrc. If the loading of your config file fails,
249 IPython starts with a bare bones configuration (no modules
250 loaded at all).
251
252 -[no]readline
253 Use the readline library, which is needed to support name com-
254 pletion and command history, among other things. It is enabled
255 by default, but may cause problems for users of X/Emacs in
256 Python comint or shell buffers.
257
258 Note that emacs 'eterm' buffers (opened with M-x term) support
259 IPython's readline and syntax coloring fine, only 'emacs' (M-x
260 shell and C-c !) buffers do not.
261
262 -screen_length|sl <n>
263 Number of lines of your screen. This is used to control print-
264 ing of very long strings. Strings longer than this number of
265 lines will be sent through a pager instead of directly printed.
266
267 The default value for this is 0, which means IPython will auto-
268 detect your screen size every time it needs to print certain
269 potentially long strings (this doesn't change the behavior of
270 the 'print' keyword, it's only triggered internally). If for
271 some reason this isn't working well (it needs curses support),
272 specify it yourself. Otherwise don't change the default.
273
274 -separate_in|si <string>
275 Separator before input prompts. Default '0.
276
277 -separate_out|so <string>
278 Separator before output prompts. Default: 0 (nothing).
279
280 -separate_out2|so2 <string>
281 Separator after output prompts. Default: 0 (nothing).
282
283 -nosep Shorthand for '-separate_in 0 -separate_out 0 -separate_out2 0'.
284 Simply removes all input/output separators.
285
286 -upgrade
287 Allows you to upgrade your IPYTHONDIR configuration when you
288 install a new version of IPython. Since new versions may
289 include new command lines options or example files, this copies
290 updated ipythonrc-type files. However, it backs up (with a .old
291 extension) all files which it overwrites so that you can merge
292 back any custimizations you might have in your personal files.
293
294 -Version
295 Print version information and exit.
296
297 -wxversion <string>
298 Select a specific version of wxPython (used in conjunction with
299 -wthread). Requires the wxversion module, part of recent
300 wxPython distributions.
301
302 -xmode <modename>
303 Mode for exception reporting. The valid modes are Plain, Con-
304 text, and Verbose.
305
306 - Plain: similar to python's normal traceback printing.
307
308 - Context: prints 5 lines of context source code around each
309 line in the traceback.
310
311 - Verbose: similar to Context, but additionally prints the vari-
312 ables currently visible where the exception happened (shortening
313 their strings if too long). This can potentially be very slow,
314 if you happen to have a huge data structure whose string repre-
315 sentation is complex to compute. Your computer may appear to
316 freeze for a while with cpu usage at 100%. If this occurs, you
317 can cancel the traceback with Ctrl-C (maybe hitting it more than
318 once).
319
320
321 EMBEDDING
322 It is possible to start an IPython instance inside your own Python pro-
323 grams. In the documentation example files there are some illustrations
324 on how to do this.
325
326 This feature allows you to evalutate dynamically the state of your
327 code, operate with your variables, analyze them, etc. Note however
328 that any changes you make to values while in the shell do NOT propagate
329 back to the running code, so it is safe to modify your values because
330 you won't break your code in bizarre ways by doing so.
331 """
18 IPython: an enhanced interactive Python shell.
19
20 A Python shell with automatic history (input and output), dynamic object
21 introspection, easier configuration, command completion, access to the

333 cmd_line_usage = __doc__
24 If invoked with no options, it executes all the files listed in sequence
25 and exits, use -i to enter interactive mode after running the files. Files
26 ending in .py will be treated as normal Python, but files ending in .ipy
27 can contain special IPython syntax (magic commands, shell expansions, etc.)
28
29 Please note that some of the configuration options are not available at the
30 command line, simply because they are not practical here. Look into your
31 ipython_config.py configuration file for details on those.
