|
6 | Installing and testing IPython at OSC systems | |
|
7 | ============================================= | |
|
8 | ||
|
9 | All components were installed from source and I have my environment set up to | |
|
10 | include ~/usr/local in my various necessary paths ($PATH, $PYTHONPATH, etc). | |
|
11 | Other than a slow filesystem for unpacking tarballs, the install went without a | |
|
12 | hitch. For each needed component, I just downloaded the source tarball, | |
|
13 | unpacked it via:: | |
|
14 | ||
|
15 | tar xzf (or xjf if it's bz2) filename.tar.{gz,bz2} | |
|
16 | ||
|
17 | and then installed them (including IPython itself) with:: | |
|
18 | ||
|
19 | cd dirname/ # path to unpacked tarball | |
|
20 | python setup.py install --prefix=~/usr/local/ | |
|
21 | ||
|
22 | The components I installed are listed below. For each one I give the main | |
|
23 | project link as well as a direct one to the file I actually dowloaded and used. | |
|
24 | ||
|
25 | - nose, used for testing: | |

|
29 | - Zope interface, used to declare interfaces in twisted and ipython. Note: | |
|
30 | you must get this from the page linked below and not fro the defaul | |
|
31 | one(http://www.zope.org/Products/ZopeInterface) because the latter has an | |
|
32 | older version, it hasn't been updated in a long time. This pypi link has | |
|
33 | the current release (3.4.1 as of this writing): | |
|

|
35 | http://pypi.python.org/packages/source/z/zope.interface/zope.interface-3.4.1.tar.gz | |
|
36 | ||
|
37 | - pyopenssl, security layer used by foolscap. Note: version 0.7 *must* be | |
|
38 | used: | |
|
39 | http://sourceforge.net/projects/pyopenssl/ | |
|
40 | http://downloads.sourceforge.net/pyopenssl/pyOpenSSL-0.6.tar.gz?modtime=1212595285&big_mirror=0 | |

|
54 | http://ipython.scipy.org/dist/ipython-0.9.1.tar.gz | |
|
55 | ||
|
56 | ||
|
57 | I then ran the ipython test suite via:: | |
|
58 | ||
|
59 | iptest -vv | |
|
60 | ||
|
61 | and it passed with only:: | |

|
74 | ||
|
75 | In three more runs of the test suite I was able to reproduce this error | |
|
76 | sometimes but not always; for now I think we can move on but we need to | |
|
77 | investigate further. Especially if we start seeing problems in real use (the | |
|
78 | test suite stresses the networking layer in particular ways that aren't | |
|
79 | necessarily typical of normal use). | |

80 | ||

90 | ||
|
91 | [... etc] | |
|
92 | ||
|
93 | and in a separate ipython session checked that the cluster is running and I can | |
|
94 | access all the engines:: | |
|
95 | ||
|
96 | In [1]: from IPython.kernel import client | |
|
97 | ||

101 | Out[3]: [0, 1, 2, 3, 4, 5, 6, 7] | |
|
102 | ||
|
103 | and run trivial code in them (after importing the ``random`` module in all | |
|
104 | engines):: | |
|
105 | ||
|
106 | In [11]: mec.execute("x=random.randint(0,10)") | |

|
120 | ||
|
121 | ||
|
122 | We'll continue conducting more complex tests later, including instaling Vision | |
|
123 | locally and running the beam demo. | |
|
124 | ||
|
125 | ||
|
126 | Michel's original instructions | |
|
127 | ============================== | |
|
128 | ||
|
129 | I got a Vision network that reproduces the beam pattern demo working: | |
|
130 | ||
|
131 | .. image:: vision_beam_pattern.png | |
|
132 | :width: 400 | |
|
133 | :target: vision_beam_pattern.png | |
|
134 | :align: center | |
|
135 | ||
|
136 | ||
|
137 | I created a package called beamPattern that provides the function run() in its | |
|
138 | __init__.py file. | |
|
139 | ||
|
140 | A subpackage beamPattern/VisionInterface provides Vision nodes for: | |
|
141 | ||
|
142 | - computing Elevation and Azimuth from a 3D vector | |
|
143 | ||
|
144 | - Reading .mat files | |
|
145 | ||
|
146 | - taking the results gathered from the engines and creating the output that a | |
|
147 | single engine would have had produced | |
|
148 | ||
|
149 | The Mec node connect to a controller. In my network it was local but an furl | |
|
150 | can be specified to connect to a remote controller. | |
|
151 | ||
|
152 | The PRun Func node is from the IPython library of nodes. the import statement | |
|
153 | is used to get the run function from the beamPattern package and bu puting | |
|
154 | "run" in the function entry of this node we push this function to the engines. | |
|
155 | In addition to the node will create input ports for all arguments of the | |
|
156 | function being pushed (i.e. the run function) | |
|
157 | ||
|
158 | The second input port on PRun Fun take an integer specifying the rank of the | |
|
159 | argument we want to scatter. All other arguments will be pushed to the engines. | |
|
160 | ||
|
161 | The ElevAzim node has a 3D vector widget and computes the El And Az values | |
|
162 | which are passed into the PRun Fun node through the ports created | |
|
163 | automatically. The Mat node allows to select the .mat file, reads it and passed | |
|
164 | the data to the locdata port created automatically on PRun Func | |
|
165 | ||
|
166 | The calculation is executed in parallel, and the results are gathered and | |
|
167 | output. Instead of having a list of 3 vectors we nd up with a list of n*3 | |
|
168 | vectors where n is the number of engines. unpackDectorResults will turn it into | |
|
169 | a list of 3. We then plot x, y, and 10*log10(z) | |
|
170 | ||
|
171 | ||
|
172 | Installation | |
|
173 | ------------ | |
|
174 | ||
|
175 | - inflate beamPattern into the site-packages directory for the MGL tools. | |
|
176 | ||
|
177 | - place the appended IPythonNodes.py and StandardNodes.py into the Vision | |
|
178 | package of the MGL tools. | |
|
179 | ||
|
180 | - place the appended items.py in the NetworkEditor package of the MGL tools | |
|
181 | ||
|
182 | - run vision for the network beamPat5_net.py:: | |
|
183 | ||
|
184 | vision beamPat5_net.py | |
|
185 | ||
|
186 | Once the network is running, you can: | |
|
187 | ||
|
188 | - double click on the MEC node and either use an emptty string for the furl to | |
|
189 | connect to a local engine or cut and paste the furl to the engine you want to | |
|
190 | use | |
|
191 | ||
|
192 | - click on the yellow lighting bold to run the network. | |
|
193 | ||
|
194 | - Try modifying the MAT file or change the Vector used top compute elevation | |
|
195 | and Azimut. | |
|
196 | ||
|
197 | ||
|
198 | Fernando's notes | |
|
199 | ================ | |
|
200 | ||
|
201 | - I had to install IPython and all its dependencies for the python used by the | |
|
202 | MGL tools. | |
|
203 | ||
|
204 | - Then I had to install scipy 0.6.0 for it, since the nodes needed Scipy. To | |
|
205 | do this I sourced the mglenv.sh script and then ran:: | |
|
206 | ||
|
207 | python setup.py install --prefix=~/usr/opt/mgl | |
|
208 | ||
|
209 | ||
|
210 | Using PBS | |
|
211 | ========= | |
|
212 | ||
|
213 | The following PBS script can be used to start the engines:: | |
|
214 | ||
|
215 | #PBS -N bgranger-ipython | |
|
216 | #PBS -j oe | |
|
217 | #PBS -l walltime=00:10:00 | |
|
218 | #PBS -l nodes=4:ppn=4 | |
|
219 | ||
|
220 | cd $PBS_O_WORKDIR | |
|
221 | export PATH=$HOME/usr/local/bin | |
|
222 | export PYTHONPATH=$HOME/usr/local/lib/python2.4/site-packages | |
|
223 | /usr/local/bin/mpiexec -n 16 ipengine | |
|
224 | ||
|
225 | ||
|
226 | If this file is called ``ipython_pbs.sh``, then the in one login windows | |
|
227 | (i.e. on the head-node -- ``opt-login01.osc.edu``), run ``ipcontroller``. In | |
|
228 | another login window on the same node, run the above script:: | |
|
229 | ||
|
230 | qsub ipython_pbs.sh | |
|
231 | ||
|
232 | If you look at the first window, you will see some diagnostic output | |
|
233 | from ipcontroller. You can then get the furl from your own | |
|
234 | ``~/.ipython/security`` directory and then connect to it remotely. | |
|
235 | ||
|
236 | You might need to set up an SSH tunnel, however; if this doesn't work as | |
|
237 | advertised:: | |
|
238 | ||
|
239 | ssh -L 10115:localhost:10105 bic | |

|
513 | -------------- | |
|
514 | ||
|
515 | The rest of this section is automatically generated for each release | |
|
516 | from the docstrings in the IPython code. Therefore the formatting is | |
|
517 | somewhat minimal, but this method has the advantage of having | |
|
518 | information always in sync with the code. | |
|
519 | ||
|
520 | A list of all the magic commands available in IPython's default | |
|
521 | installation follows. This is similar to what you'll see by simply | |
|
522 | typing %magic at the prompt, but that will also give you information | |
|
523 | about magic commands you may have added as part of your personal | |
|
524 | customizations. | |
|
525 | ||
|
526 | .. magic_start | |
|
527 | ||
|
528 | **%Exit**:: | |
|
529 | ||
|
530 | Exit IPython without confirmation. | |
|
531 | ||
|
532 | **%Pprint**:: | |
|
533 | ||
|
534 | Toggle pretty printing on/off. | |
|
535 | ||
|
536 | **%alias**:: | |
|
537 | ||
|
538 | Define an alias for a system command. | |
|
539 | ||
|
540 | '%alias alias_name cmd' defines 'alias_name' as an alias for 'cmd' | |
|
541 | ||
|
542 | Then, typing 'alias_name params' will execute the system command 'cmd | |
|
543 | params' (from your underlying operating system). | |
|
544 | ||
|
545 | Aliases have lower precedence than magic functions and Python normal | |
|
546 | variables, so if 'foo' is both a Python variable and an alias, the | |
|
547 | alias can not be executed until 'del foo' removes the Python variable. | |
|
548 | ||
|
549 | You can use the %l specifier in an alias definition to represent the | |
|
550 | whole line when the alias is called. For example: | |
|
551 | ||
|
552 | In [2]: alias all echo "Input in brackets: <%l>"\ | |
|
553 | In [3]: all hello world\ | |
|
554 | Input in brackets: <hello world> | |
|
555 | ||
|
556 | You can also define aliases with parameters using %s specifiers (one | |
|
557 | per parameter): | |
|
558 | ||
|
559 | In [1]: alias parts echo first %s second %s\ | |
|
560 | In [2]: %parts A B\ | |
|
561 | first A second B\ | |
|
562 | In [3]: %parts A\ | |
|
563 | Incorrect number of arguments: 2 expected.\ | |
|
564 | parts is an alias to: 'echo first %s second %s' | |
|
565 | ||
|
566 | Note that %l and %s are mutually exclusive. You can only use one or | |
|
567 | the other in your aliases. | |
|
568 | ||
|
569 | Aliases expand Python variables just like system calls using ! or !! | |
|
570 | do: all expressions prefixed with '$' get expanded. For details of | |
|
571 | the semantic rules, see PEP-215: | |
|
572 | http://www.python.org/peps/pep-0215.html. This is the library used by | |
|
573 | IPython for variable expansion. If you want to access a true shell | |
|
574 | variable, an extra $ is necessary to prevent its expansion by IPython: | |
|
575 | ||
|
576 | In [6]: alias show echo\ | |
|
577 | In [7]: PATH='A Python string'\ | |
|
578 | In [8]: show $PATH\ | |
|
579 | A Python string\ | |
|
580 | In [9]: show $$PATH\ | |
|
581 | /usr/local/lf9560/bin:/usr/local/intel/compiler70/ia32/bin:... | |
|
582 | ||
|
583 | You can use the alias facility to acess all of $PATH. See the %rehash | |
|
584 | and %rehashx functions, which automatically create aliases for the | |
|
585 | contents of your $PATH. | |
|
586 | ||
|
587 | If called with no parameters, %alias prints the current alias table. | |
|

594 | ||
|
595 | %autocall [mode] | |
|
596 | ||
|
597 | The mode can be one of: 0->Off, 1->Smart, 2->Full. If not given, the | |
|
598 | value is toggled on and off (remembering the previous state). | |
|
599 | ||
|
600 | In more detail, these values mean: | |
|
601 | ||
|
602 | 0 -> fully disabled | |
|
603 | ||
|
604 | 1 -> active, but do not apply if there are no arguments on the line. | |
|
605 | ||
|
606 | In this mode, you get: | |
|
607 | ||
|
608 | In [1]: callable | |
|
609 | Out[1]: <built-in function callable> | |
|
610 | ||
|
611 | In [2]: callable 'hello' | |
|
612 | ------> callable('hello') | |
|
613 | Out[2]: False | |
|
614 | ||
|
615 | 2 -> Active always. Even if no arguments are present, the callable | |
|
616 | object is called: | |
|
617 | ||
|
618 | In [4]: callable | |
|
619 | ------> callable() | |
|
620 | ||
|
621 | Note that even with autocall off, you can still use '/' at the start of | |
|
622 | a line to treat the first argument on the command line as a function | |
|
623 | and add parentheses to it: | |
|
624 | ||
|
625 | In [8]: /str 43 | |
|
626 | ------> str(43) | |
|
627 | Out[8]: '43' | |
|
628 | ||
|
629 | **%autoindent**:: | |
|
630 | ||
|
631 | Toggle autoindent on/off (if available). | |
|
632 | ||
|
633 | **%automagic**:: | |
|
634 | ||
|
635 | Make magic functions callable without having to type the initial %. | |
|
636 | ||
|
637 | Without argumentsl toggles on/off (when off, you must call it as | |
|
638 | %automagic, of course). With arguments it sets the value, and you can | |
|
639 | use any of (case insensitive): | |
|
640 | ||
|
641 | - on,1,True: to activate | |
|
642 | ||
|
643 | - off,0,False: to deactivate. | |
|
644 | ||
|
645 | Note that magic functions have lowest priority, so if there's a | |
|
646 | variable whose name collides with that of a magic fn, automagic won't | |
|
647 | work for that function (you get the variable instead). However, if you | |
|
648 | delete the variable (del var), the previously shadowed magic function | |
|
649 | becomes visible to automagic again. | |
|
650 | ||
|
651 | **%bg**:: | |
|
652 | ||
|
653 | Run a job in the background, in a separate thread. | |
|
654 | ||
|
655 | For example, | |
|
656 | ||
|
657 | %bg myfunc(x,y,z=1) | |
|
658 | ||
|
659 | will execute 'myfunc(x,y,z=1)' in a background thread. As soon as the | |
|
660 | execution starts, a message will be printed indicating the job | |
|
661 | number. If your job number is 5, you can use | |
|
662 | ||
|
663 | myvar = jobs.result(5) or myvar = jobs[5].result | |
|
664 | ||
|
665 | to assign this result to variable 'myvar'. | |
|
666 | ||
|
667 | IPython has a job manager, accessible via the 'jobs' object. You can | |
|
668 | type jobs? to get more information about it, and use jobs.<TAB> to see | |
|
669 | its attributes. All attributes not starting with an underscore are | |
|
670 | meant for public use. | |
|
671 | ||
|
672 | In particular, look at the jobs.new() method, which is used to create | |
|
673 | new jobs. This magic %bg function is just a convenience wrapper | |
|
674 | around jobs.new(), for expression-based jobs. If you want to create a | |
|
675 | new job with an explicit function object and arguments, you must call | |
|
676 | jobs.new() directly. | |
|
677 | ||
|
678 | The jobs.new docstring also describes in detail several important | |
|
679 | caveats associated with a thread-based model for background job | |
|
680 | execution. Type jobs.new? for details. | |
|
681 | ||
|
682 | You can check the status of all jobs with jobs.status(). | |
|
683 | ||
|
684 | The jobs variable is set by IPython into the Python builtin namespace. | |
|
685 | If you ever declare a variable named 'jobs', you will shadow this | |
|
686 | name. You can either delete your global jobs variable to regain | |
|
687 | access to the job manager, or make a new name and assign it manually | |
|
688 | to the manager (stored in IPython's namespace). For example, to | |
|
689 | assign the job manager to the Jobs name, use: | |
|
690 | ||
|
691 | Jobs = __builtins__.jobs | |
|
692 | ||
|
693 | **%bookmark**:: | |
|
694 | ||
|
695 | Manage IPython's bookmark system. | |
|
696 | ||
|
697 | %bookmark <name> - set bookmark to current dir | |
|
698 | %bookmark <name> <dir> - set bookmark to <dir> | |
|
699 | %bookmark -l - list all bookmarks | |
|
700 | %bookmark -d <name> - remove bookmark | |
|
701 | %bookmark -r - remove all bookmarks | |
|
702 | ||
|
703 | You can later on access a bookmarked folder with: | |
|
704 | %cd -b <name> | |
|
705 | or simply '%cd <name>' if there is no directory called <name> AND | |
|
706 | there is such a bookmark defined. | |
|
707 | ||
|
708 | Your bookmarks persist through IPython sessions, but they are | |
|
709 | associated with each profile. | |
|
710 | ||
|
711 | **%cd**:: | |
|
712 | ||
|
713 | Change the current working directory. | |
|
714 | ||
|
715 | This command automatically maintains an internal list of directories | |
|
716 | you visit during your IPython session, in the variable _dh. The | |
|
717 | command %dhist shows this history nicely formatted. You can also | |
|
718 | do 'cd -<tab>' to see directory history conveniently. | |
|
719 | ||
|
720 | Usage: | |
|
721 | ||
|
722 | cd 'dir': changes to directory 'dir'. | |
|
723 | ||
|
724 | cd -: changes to the last visited directory. | |
|
725 | ||
|
726 | cd -<n>: changes to the n-th directory in the directory history. | |
|
727 | ||
|
728 | cd -b <bookmark_name>: jump to a bookmark set by %bookmark | |
|
729 | (note: cd <bookmark_name> is enough if there is no | |
|
730 | directory <bookmark_name>, but a bookmark with the name exists.) | |
|
731 | 'cd -b <tab>' allows you to tab-complete bookmark names. | |
|
732 | ||
|
733 | Options: | |
|
734 | ||
|
735 | -q: quiet. Do not print the working directory after the cd command is | |
|
736 | executed. By default IPython's cd command does print this directory, | |
|
737 | since the default prompts do not display path information. | |
|
738 | ||
|
739 | Note that !cd doesn't work for this purpose because the shell where | |
|
740 | !command runs is immediately discarded after executing 'command'. | |
|
741 | ||
|
742 | **%clear**:: | |
|
743 | ||
|
744 | Clear various data (e.g. stored history data) | |
|
745 | ||
|
746 | %clear out - clear output history | |
|
747 | %clear in - clear input history | |
|
748 | %clear shadow_compress - Compresses shadow history (to speed up ipython) | |
|
749 | %clear shadow_nuke - permanently erase all entries in shadow history | |
|
750 | %clear dhist - clear dir history | |
|
751 | ||
|
752 | **%color_info**:: | |
|
753 | ||
|
754 | Toggle color_info. | |
|
755 | ||
|
756 | The color_info configuration parameter controls whether colors are | |
|
757 | used for displaying object details (by things like %psource, %pfile or | |
|
758 | the '?' system). This function toggles this value with each call. | |
|
759 | ||
|
760 | Note that unless you have a fairly recent pager (less works better | |
|
761 | than more) in your system, using colored object information displays | |
|
762 | will not work properly. Test it and see. | |
|
763 | ||
|
764 | **%colors**:: | |
|
765 | ||
|
766 | Switch color scheme for prompts, info system and exception handlers. | |
|
767 | ||
|
768 | Currently implemented schemes: NoColor, Linux, LightBG. | |
|
769 | ||
|
770 | Color scheme names are not case-sensitive. | |
|
771 | ||
|
772 | **%cpaste**:: | |
|
773 | ||
|
774 | Allows you to paste & execute a pre-formatted code block from clipboard | |
|
775 | ||
|
776 | You must terminate the block with '--' (two minus-signs) alone on the | |
|
777 | line. You can also provide your own sentinel with '%paste -s %%' ('%%' | |
|
778 | is the new sentinel for this operation) | |
|
779 | ||
|
780 | The block is dedented prior to execution to enable execution of method | |
|
781 | definitions. '>' and '+' characters at the beginning of a line are | |
|
782 | ignored, to allow pasting directly from e-mails or diff files. The | |
|
783 | executed block is also assigned to variable named 'pasted_block' for | |
|
784 | later editing with '%edit pasted_block'. | |
|
785 | ||
|
786 | You can also pass a variable name as an argument, e.g. '%cpaste foo'. | |
|
787 | This assigns the pasted block to variable 'foo' as string, without | |
|
788 | dedenting or executing it. | |
|
789 | ||
|
790 | Do not be alarmed by garbled output on Windows (it's a readline bug). | |
|
791 | Just press enter and type -- (and press enter again) and the block | |
|
792 | will be what was just pasted. | |
|
793 | ||
|
794 | IPython statements (magics, shell escapes) are not supported (yet). | |
|
795 | ||
|
796 | **%debug**:: | |
|
797 | ||
|
798 | Activate the interactive debugger in post-mortem mode. | |
|
799 | ||
|
800 | If an exception has just occurred, this lets you inspect its stack | |
|
801 | frames interactively. Note that this will always work only on the last | |
|
802 | traceback that occurred, so you must call this quickly after an | |
|
803 | exception that you wish to inspect has fired, because if another one | |
|
804 | occurs, it clobbers the previous one. | |
|
805 | ||
|
806 | If you want IPython to automatically do this on every exception, see | |
|
807 | the %pdb magic for more details. | |
|
808 | ||
|
809 | **%dhist**:: | |
|
810 | ||
|
811 | Print your history of visited directories. | |
|
812 | ||
|
813 | %dhist -> print full history\ | |
|
814 | %dhist n -> print last n entries only\ | |
|
815 | %dhist n1 n2 -> print entries between n1 and n2 (n1 not included)\ | |
|
816 | ||
|
817 | This history is automatically maintained by the %cd command, and | |
|
818 | always available as the global list variable _dh. You can use %cd -<n> | |
|
819 | to go to directory number <n>. | |
|
820 | ||
|
821 | Note that most of time, you should view directory history by entering | |
|
822 | cd -<TAB>. | |
|
823 | ||
|
824 | **%dirs**:: | |
|
825 | ||
|
826 | Return the current directory stack. | |
|
827 | ||
|
828 | **%doctest_mode**:: | |
|
829 | ||
|
830 | Toggle doctest mode on and off. | |
|
831 | ||
|
832 | This mode allows you to toggle the prompt behavior between normal | |
|
833 | IPython prompts and ones that are as similar to the default IPython | |
|
834 | interpreter as possible. | |
|
835 | ||
|
836 | It also supports the pasting of code snippets that have leading '>>>' | |
|
837 | and '...' prompts in them. This means that you can paste doctests from | |
|
838 | files or docstrings (even if they have leading whitespace), and the | |
|
839 | code will execute correctly. You can then use '%history -tn' to see | |
|
840 | the translated history without line numbers; this will give you the | |
|
841 | input after removal of all the leading prompts and whitespace, which | |
|
842 | can be pasted back into an editor. | |
|
843 | ||
|
844 | With these features, you can switch into this mode easily whenever you | |
|
845 | need to do testing and changes to doctests, without having to leave | |
|
846 | your existing IPython session. | |
|
847 | ||
|
848 | **%ed**:: | |
|
849 | ||
|
850 | Alias to %edit. | |
|
851 | ||
|
852 | **%edit**:: | |
|
853 | ||
|
854 | Bring up an editor and execute the resulting code. | |
|
855 | ||
|
856 | Usage: | |
|
857 | %edit [options] [args] | |
|
858 | ||
|
859 | %edit runs IPython's editor hook. The default version of this hook is | |
|
860 | set to call the __IPYTHON__.rc.editor command. This is read from your | |
|
861 | environment variable $EDITOR. If this isn't found, it will default to | |
|
862 | vi under Linux/Unix and to notepad under Windows. See the end of this | |
|
863 | docstring for how to change the editor hook. | |
|
864 | ||
|
865 | You can also set the value of this editor via the command line option | |
|
866 | '-editor' or in your ipythonrc file. This is useful if you wish to use | |
|
867 | specifically for IPython an editor different from your typical default | |
|
868 | (and for Windows users who typically don't set environment variables). | |
|
869 | ||
|
870 | This command allows you to conveniently edit multi-line code right in | |
|
871 | your IPython session. | |
|
872 | ||
|
873 | If called without arguments, %edit opens up an empty editor with a | |
|
874 | temporary file and will execute the contents of this file when you | |
|
875 | close it (don't forget to save it!). | |
|
876 | ||
|
877 | ||
|
878 | Options: | |
|
879 | ||
|
880 | -n <number>: open the editor at a specified line number. By default, | |
|
881 | the IPython editor hook uses the unix syntax 'editor +N filename', but | |
|
882 | you can configure this by providing your own modified hook if your | |
|
883 | favorite editor supports line-number specifications with a different | |
|
884 | syntax. | |
|
885 | ||
|
886 | -p: this will call the editor with the same data as the previous time | |
|
887 | it was used, regardless of how long ago (in your current session) it | |
|
888 | was. | |
|
889 | ||
|
890 | -r: use 'raw' input. This option only applies to input taken from the | |
|
891 | user's history. By default, the 'processed' history is used, so that | |
|
892 | magics are loaded in their transformed version to valid Python. If | |
|
893 | this option is given, the raw input as typed as the command line is | |
|
894 | used instead. When you exit the editor, it will be executed by | |
|
895 | IPython's own processor. | |
|
896 | ||
|
897 | -x: do not execute the edited code immediately upon exit. This is | |
|
898 | mainly useful if you are editing programs which need to be called with | |
|
899 | command line arguments, which you can then do using %run. | |
|
900 | ||
|
901 | ||
|
902 | Arguments: | |
|
903 | ||
|
904 | If arguments are given, the following possibilites exist: | |
|
905 | ||
|
906 | - The arguments are numbers or pairs of colon-separated numbers (like | |
|
907 | 1 4:8 9). These are interpreted as lines of previous input to be | |
|
908 | loaded into the editor. The syntax is the same of the %macro command. | |
|
909 | ||
|
910 | - If the argument doesn't start with a number, it is evaluated as a | |
|
911 | variable and its contents loaded into the editor. You can thus edit | |
|
912 | any string which contains python code (including the result of | |
|
913 | previous edits). | |
|
914 | ||
|
915 | - If the argument is the name of an object (other than a string), | |
|
916 | IPython will try to locate the file where it was defined and open the | |
|
917 | editor at the point where it is defined. You can use `%edit function` | |
|
918 | to load an editor exactly at the point where 'function' is defined, | |
|
919 | edit it and have the file be executed automatically. | |
|
920 | ||
|
921 | If the object is a macro (see %macro for details), this opens up your | |
|
922 | specified editor with a temporary file containing the macro's data. | |
|
923 | Upon exit, the macro is reloaded with the contents of the file. | |
|
924 | ||
|
925 | Note: opening at an exact line is only supported under Unix, and some | |
|
926 | editors (like kedit and gedit up to Gnome 2.8) do not understand the | |
|
927 | '+NUMBER' parameter necessary for this feature. Good editors like | |
|
928 | (X)Emacs, vi, jed, pico and joe all do. | |
|
929 | ||
|
930 | - If the argument is not found as a variable, IPython will look for a | |
|
931 | file with that name (adding .py if necessary) and load it into the | |
|
932 | editor. It will execute its contents with execfile() when you exit, | |
|
933 | loading any code in the file into your interactive namespace. | |
|
934 | ||
|
935 | After executing your code, %edit will return as output the code you | |
|
936 | typed in the editor (except when it was an existing file). This way | |
|
937 | you can reload the code in further invocations of %edit as a variable, | |
|
938 | via _<NUMBER> or Out[<NUMBER>], where <NUMBER> is the prompt number of | |
|
939 | the output. | |
|
940 | ||
|
941 | Note that %edit is also available through the alias %ed. | |
|
942 | ||
|
943 | This is an example of creating a simple function inside the editor and | |
|
944 | then modifying it. First, start up the editor: | |
|
945 | ||
|
946 | In [1]: ed\ | |
|
947 | Editing... done. Executing edited code...\ | |
|
948 | Out[1]: 'def foo():\n print "foo() was defined in an editing session"\n' | |
|
949 | ||
|
950 | We can then call the function foo(): | |
|
951 | ||
|
952 | In [2]: foo()\ | |
|
953 | foo() was defined in an editing session | |
|
954 | ||
|
955 | Now we edit foo. IPython automatically loads the editor with the | |
|
956 | (temporary) file where foo() was previously defined: | |
|
957 | ||
|
958 | In [3]: ed foo\ | |
|
959 | Editing... done. Executing edited code... | |
|
960 | ||
|
961 | And if we call foo() again we get the modified version: | |
|
962 | ||
|
963 | In [4]: foo()\ | |
|
964 | foo() has now been changed! | |
|
965 | ||
|
966 | Here is an example of how to edit a code snippet successive | |
|
967 | times. First we call the editor: | |
|
968 | ||
|
969 | In [8]: ed\ | |
|
970 | Editing... done. Executing edited code...\ | |
|
971 | hello\ | |
|
972 | Out[8]: "print 'hello'\n" | |
|
973 | ||
|
974 | Now we call it again with the previous output (stored in _): | |
|
975 | ||
|
976 | In [9]: ed _\ | |
|
977 | Editing... done. Executing edited code...\ | |
|
978 | hello world\ | |
|
979 | Out[9]: "print 'hello world'\n" | |
|
980 | ||
|
981 | Now we call it with the output #8 (stored in _8, also as Out[8]): | |
|
982 | ||
|
983 | In [10]: ed _8\ | |
|
984 | Editing... done. Executing edited code...\ | |
|
985 | hello again\ | |
|
986 | Out[10]: "print 'hello again'\n" | |
|
987 | ||
|
988 | ||
|
989 | Changing the default editor hook: | |
|
990 | ||
|
991 | If you wish to write your own editor hook, you can put it in a | |
|
992 | configuration file which you load at startup time. The default hook | |
|
993 | is defined in the IPython.hooks module, and you can use that as a | |
|
994 | starting example for further modifications. That file also has | |
|
995 | general instructions on how to set a new hook for use once you've | |
|
996 | defined it. | |
|
997 | ||
|
998 | **%env**:: | |
|
999 | ||
|
1000 | List environment variables. | |
|
1001 | ||
|
1002 | **%exit**:: | |
|
1003 | ||
|
1004 | Exit IPython, confirming if configured to do so. | |
|
1005 | ||
|
1006 | You can configure whether IPython asks for confirmation upon exit by | |
|
1007 | setting the confirm_exit flag in the ipythonrc file. | |
|
1008 | ||
|
1009 | **%hist**:: | |
|
1010 | ||
|
1011 | Alternate name for %history. | |
|
1012 | ||
|
1013 | **%history**:: | |
|
1014 | ||
|
1015 | Print input history (_i<n> variables), with most recent last. | |
|
1016 | ||
|
1017 | %history -> print at most 40 inputs (some may be multi-line)\ | |
|
1018 | %history n -> print at most n inputs\ | |
|
1019 | %history n1 n2 -> print inputs between n1 and n2 (n2 not included)\ | |
|
1020 | ||
|
1021 | Each input's number <n> is shown, and is accessible as the | |
|
1022 | automatically generated variable _i<n>. Multi-line statements are | |
|
1023 | printed starting at a new line for easy copy/paste. | |
|
1024 | ||
|
1025 | ||
|
1026 | Options: | |
|
1027 | ||
|
1028 | -n: do NOT print line numbers. This is useful if you want to get a | |
|
1029 | printout of many lines which can be directly pasted into a text | |
|
1030 | editor. | |
|
1031 | ||
|
1032 | This feature is only available if numbered prompts are in use. | |
|
1033 | ||
|
1034 | -t: (default) print the 'translated' history, as IPython understands it. | |
|
1035 | IPython filters your input and converts it all into valid Python source | |
|
1036 | before executing it (things like magics or aliases are turned into | |
|
1037 | function calls, for example). With this option, you'll see the native | |
|
1038 | history instead of the user-entered version: '%cd /' will be seen as | |
|
1039 | '_ip.magic("%cd /")' instead of '%cd /'. | |
|
1040 | ||
|
1041 | -r: print the 'raw' history, i.e. the actual commands you typed. | |
|
1042 | ||
|
1043 | -g: treat the arg as a pattern to grep for in (full) history. | |
|
1044 | This includes the "shadow history" (almost all commands ever written). | |
|
1045 | Use '%hist -g' to show full shadow history (may be very long). | |
|
1046 | In shadow history, every index nuwber starts with 0. | |
|
1047 | ||
|
1048 | -f FILENAME: instead of printing the output to the screen, redirect it to | |
|
1049 | the given file. The file is always overwritten, though IPython asks for | |
|
1050 | confirmation first if it already exists. | |
|
1051 | ||
|
1052 | **%logoff**:: | |
|
1053 | ||
|
1054 | Temporarily stop logging. | |
|
1055 | ||
|
1056 | You must have previously started logging. | |
|
1057 | ||
|
1058 | **%logon**:: | |
|
1059 | ||
|
1060 | Restart logging. | |
|
1061 | ||
|
1062 | This function is for restarting logging which you've temporarily | |
|
1063 | stopped with %logoff. For starting logging for the first time, you | |
|
1064 | must use the %logstart function, which allows you to specify an | |
|
1065 | optional log filename. | |
|
1066 | ||
|
1067 | **%logstart**:: | |
|
1068 | ||
|
1069 | Start logging anywhere in a session. | |
|
1070 | ||
|
1071 | %logstart [-o|-r|-t] [log_name [log_mode]] | |
|
1072 | ||
|
1073 | If no name is given, it defaults to a file named 'ipython_log.py' in your | |
|
1074 | current directory, in 'rotate' mode (see below). | |
|
1075 | ||
|
1076 | '%logstart name' saves to file 'name' in 'backup' mode. It saves your | |
|
1077 | history up to that point and then continues logging. | |
|
1078 | ||
|
1079 | %logstart takes a second optional parameter: logging mode. This can be one | |
|
1080 | of (note that the modes are given unquoted):\ | |
|
1081 | append: well, that says it.\ | |
|
1082 | backup: rename (if exists) to name~ and start name.\ | |
|
1083 | global: single logfile in your home dir, appended to.\ | |
|
1084 | over : overwrite existing log.\ | |
|
1085 | rotate: create rotating logs name.1~, name.2~, etc. | |
|
1086 | ||
|
1087 | Options: | |
|
1088 | ||
|
1089 | -o: log also IPython's output. In this mode, all commands which | |
|
1090 | generate an Out[NN] prompt are recorded to the logfile, right after | |
|
1091 | their corresponding input line. The output lines are always | |
|
1092 | prepended with a '#[Out]# ' marker, so that the log remains valid | |
|
1093 | Python code. | |
|
1094 | ||
|
1095 | Since this marker is always the same, filtering only the output from | |
|
1096 | a log is very easy, using for example a simple awk call: | |
|
1097 | ||
|
1098 | awk -F'#\[Out\]# ' '{if($2) {print $2}}' ipython_log.py | |
|
1099 | ||
|
1100 | -r: log 'raw' input. Normally, IPython's logs contain the processed | |
|
1101 | input, so that user lines are logged in their final form, converted | |
|
1102 | into valid Python. For example, %Exit is logged as | |
|
1103 | '_ip.magic("Exit"). If the -r flag is given, all input is logged | |
|
1104 | exactly as typed, with no transformations applied. | |
|
1105 | ||
|
1106 | -t: put timestamps before each input line logged (these are put in | |
|
1107 | comments). | |
|
1108 | ||
|
1109 | **%logstate**:: | |
|
1110 | ||
|
1111 | Print the status of the logging system. | |
|
1112 | ||
|
1113 | **%logstop**:: | |
|
1114 | ||
|
1115 | Fully stop logging and close log file. | |
|
1116 | ||
|
1117 | In order to start logging again, a new %logstart call needs to be made, | |
|
1118 | possibly (though not necessarily) with a new filename, mode and other | |
|
1119 | options. | |
|
1120 | ||
|
1121 | **%lsmagic**:: | |
|
1122 | ||
|
1123 | List currently available magic functions. | |
|
1124 | ||
|
1125 | **%macro**:: | |
|
1126 | ||
|
1127 | Define a set of input lines as a macro for future re-execution. | |
|
1128 | ||
|
1129 | Usage:\ | |
|
1130 | %macro [options] name n1-n2 n3-n4 ... n5 .. n6 ... | |
|
1131 | ||
|
1132 | Options: | |
|
1133 | ||
|
1134 | -r: use 'raw' input. By default, the 'processed' history is used, | |
|
1135 | so that magics are loaded in their transformed version to valid | |
|
1136 | Python. If this option is given, the raw input as typed as the | |
|
1137 | command line is used instead. | |
|
1138 | ||
|
1139 | This will define a global variable called `name` which is a string | |
|
1140 | made of joining the slices and lines you specify (n1,n2,... numbers | |
|
1141 | above) from your input history into a single string. This variable | |
|
1142 | acts like an automatic function which re-executes those lines as if | |
|
1143 | you had typed them. You just type 'name' at the prompt and the code | |
|
1144 | executes. | |
|
1145 | ||
|
1146 | The notation for indicating number ranges is: n1-n2 means 'use line | |
|
1147 | numbers n1,...n2' (the endpoint is included). That is, '5-7' means | |
|
1148 | using the lines numbered 5,6 and 7. | |
|
1149 | ||
|
1150 | Note: as a 'hidden' feature, you can also use traditional python slice | |
|
1151 | notation, where N:M means numbers N through M-1. | |
|
1152 | ||
|
1153 | For example, if your history contains (%hist prints it): | |
|
1154 | ||
|
1155 | 44: x=1\ | |
|
1156 | 45: y=3\ | |
|
1157 | 46: z=x+y\ | |
|
1158 | 47: print x\ | |
|
1159 | 48: a=5\ | |
|
1160 | 49: print 'x',x,'y',y\ | |
|
1161 | ||
|
1162 | you can create a macro with lines 44 through 47 (included) and line 49 | |
|
1163 | called my_macro with: | |
|
1164 | ||
|
1165 | In [51]: %macro my_macro 44-47 49 | |
|
1166 | ||
|
1167 | Now, typing `my_macro` (without quotes) will re-execute all this code | |
|
1168 | in one pass. | |
|
1169 | ||
|
1170 | You don't need to give the line-numbers in order, and any given line | |
|
1171 | number can appear multiple times. You can assemble macros with any | |
|
1172 | lines from your input history in any order. | |
|
1173 | ||
|
1174 | The macro is a simple object which holds its value in an attribute, | |
|
1175 | but IPython's display system checks for macros and executes them as | |
|
1176 | code instead of printing them when you type their name. | |
|
1177 | ||
|
1178 | You can view a macro's contents by explicitly printing it with: | |
|
1179 | ||
|
1180 | 'print macro_name'. | |
|
1181 | ||
|
1182 | For one-off cases which DON'T contain magic function calls in them you | |
|
1183 | can obtain similar results by explicitly executing slices from your | |
|
1184 | input history with: | |
|
1185 | ||
|
1186 | In [60]: exec In[44:48]+In[49] | |
|
1187 | ||
|
1188 | **%magic**:: | |
|
1189 | ||
|
1190 | Print information about the magic function system. | |
|
1191 | ||
|
1192 | **%mglob**:: | |
|
1193 | ||
|
1194 | This program allows specifying filenames with "mglob" mechanism. | |
|
1195 | Supported syntax in globs (wilcard matching patterns):: | |
|
1196 | ||
|
1197 | *.cpp ?ellowo* | |
|
1198 | - obvious. Differs from normal glob in that dirs are not included. | |
|
1199 | Unix users might want to write this as: "*.cpp" "?ellowo*" | |
|
1200 | rec:/usr/share=*.txt,*.doc | |
|
1201 | - get all *.txt and *.doc under /usr/share, | |
|
1202 | recursively | |
|
1203 | rec:/usr/share | |
|
1204 | - All files under /usr/share, recursively | |
|
1205 | rec:*.py | |
|
1206 | - All .py files under current working dir, recursively | |
|
1207 | foo | |
|
1208 | - File or dir foo | |
|
1209 | !*.bak readme* | |
|
1210 | - readme*, exclude files ending with .bak | |
|
1211 | !.svn/ !.hg/ !*_Data/ rec:. | |
|
1212 | - Skip .svn, .hg, foo_Data dirs (and their subdirs) in recurse. | |
|
1213 | Trailing / is the key, \ does not work! | |
|
1214 | dir:foo | |
|
1215 | - the directory foo if it exists (not files in foo) | |
|
1216 | dir:* | |
|
1217 | - all directories in current folder | |
|
1218 | foo.py bar.* !h* rec:*.py | |
|
1219 | - Obvious. !h* exclusion only applies for rec:*.py. | |
|
1220 | foo.py is *not* included twice. | |
|
1221 | @filelist.txt | |
|
1222 | - All files listed in 'filelist.txt' file, on separate lines. | |
|
1223 | ||
|
1224 | **%page**:: | |
|
1225 | ||
|
1226 | Pretty print the object and display it through a pager. | |
|
1227 | ||
|
1228 | %page [options] OBJECT | |
|
1229 | ||
|
1230 | If no object is given, use _ (last output). | |
|
1231 | ||
|
1232 | Options: | |
|
1233 | ||
|
1234 | -r: page str(object), don't pretty-print it. | |
|
1235 | ||
|
1236 | **%pdb**:: | |
|
1237 | ||
|
1238 | Control the automatic calling of the pdb interactive debugger. | |
|
1239 | ||
|
1240 | Call as '%pdb on', '%pdb 1', '%pdb off' or '%pdb 0'. If called without | |
|
1241 | argument it works as a toggle. | |
|
1242 | ||
|
1243 | When an exception is triggered, IPython can optionally call the | |
|
1244 | interactive pdb debugger after the traceback printout. %pdb toggles | |
|
1245 | this feature on and off. | |
|
1246 | ||
|
1247 | The initial state of this feature is set in your ipythonrc | |
|
1248 | configuration file (the variable is called 'pdb'). | |
|
1249 | ||
|
1250 | If you want to just activate the debugger AFTER an exception has fired, | |
|
1251 | without having to type '%pdb on' and rerunning your code, you can use | |
|
1252 | the %debug magic. | |
|
1253 | ||
|
1254 | **%pdef**:: | |
|
1255 | ||
|
1256 | Print the definition header for any callable object. | |
|
1257 | ||
|
1258 | If the object is a class, print the constructor information. | |
|
1259 | ||
|
1260 | **%pdoc**:: | |
|
1261 | ||
|
1262 | Print the docstring for an object. | |
|
1263 | ||
|
1264 | If the given object is a class, it will print both the class and the | |
|
1265 | constructor docstrings. | |
|
1266 | ||
|
1267 | **%pfile**:: | |
|
1268 | ||
|
1269 | Print (or run through pager) the file where an object is defined. | |
|
1270 | ||
|
1271 | The file opens at the line where the object definition begins. IPython | |
|
1272 | will honor the environment variable PAGER if set, and otherwise will | |
|
1273 | do its best to print the file in a convenient form. | |
|
1274 | ||
|
1275 | If the given argument is not an object currently defined, IPython will | |
|
1276 | try to interpret it as a filename (automatically adding a .py extension | |
|
1277 | if needed). You can thus use %pfile as a syntax highlighting code | |
|
1278 | viewer. | |
|
1279 | ||
|
1280 | **%pinfo**:: | |
|
1281 | ||
|
1282 | Provide detailed information about an object. | |
|
1283 | ||
|
1284 | '%pinfo object' is just a synonym for object? or ?object. | |
|
1285 | ||
|
1286 | **%popd**:: | |
|
1287 | ||
|
1288 | Change to directory popped off the top of the stack. | |
|
1289 | ||
|
1290 | **%profile**:: | |
|
1291 | ||
|
1292 | Print your currently active IPyhton profile. | |
|
1293 | ||
|
1294 | **%prun**:: | |
|
1295 | ||
|
1296 | Run a statement through the python code profiler. | |
|
1297 | ||
|
1298 | Usage:\ | |
|
1299 | %prun [options] statement | |
|
1300 | ||
|
1301 | The given statement (which doesn't require quote marks) is run via the | |
|
1302 | python profiler in a manner similar to the profile.run() function. | |
|
1303 | Namespaces are internally managed to work correctly; profile.run | |
|
1304 | cannot be used in IPython because it makes certain assumptions about | |
|
1305 | namespaces which do not hold under IPython. | |
|
1306 | ||
|
1307 | Options: | |
|
1308 | ||
|
1309 | -l <limit>: you can place restrictions on what or how much of the | |
|
1310 | profile gets printed. The limit value can be: | |
|
1311 | ||
|
1312 | * A string: only information for function names containing this string | |
|
1313 | is printed. | |
|
1314 | ||
|
1315 | * An integer: only these many lines are printed. | |
|
1316 | ||
|
1317 | * A float (between 0 and 1): this fraction of the report is printed | |
|
1318 | (for example, use a limit of 0.4 to see the topmost 40% only). | |
|
1319 | ||
|
1320 | You can combine several limits with repeated use of the option. For | |
|
1321 | example, '-l __init__ -l 5' will print only the topmost 5 lines of | |
|
1322 | information about class constructors. | |
|
1323 | ||
|
1324 | -r: return the pstats.Stats object generated by the profiling. This | |
|
1325 | object has all the information about the profile in it, and you can | |
|
1326 | later use it for further analysis or in other functions. | |
|
1327 | ||
|
1328 | -s <key>: sort profile by given key. You can provide more than one key | |
|
1329 | by using the option several times: '-s key1 -s key2 -s key3...'. The | |
|
1330 | default sorting key is 'time'. | |
|
1331 | ||
|
1332 | The following is copied verbatim from the profile documentation | |
|
1333 | referenced below: | |
|
1334 | ||
|
1335 | When more than one key is provided, additional keys are used as | |
|
1336 | secondary criteria when the there is equality in all keys selected | |
|
1337 | before them. | |
|
1338 | ||
|
1339 | Abbreviations can be used for any key names, as long as the | |
|
1340 | abbreviation is unambiguous. The following are the keys currently | |
|
1341 | defined: | |
|
1342 | ||
|
1343 | Valid Arg Meaning\ | |
|
1344 | "calls" call count\ | |
|
1345 | "cumulative" cumulative time\ | |
|
1346 | "file" file name\ | |
|
1347 | "module" file name\ | |
|
1348 | "pcalls" primitive call count\ | |
|
1349 | "line" line number\ | |
|
1350 | "name" function name\ | |
|
1351 | "nfl" name/file/line\ | |
|
1352 | "stdname" standard name\ | |
|
1353 | "time" internal time | |
|
1354 | ||
|
1355 | Note that all sorts on statistics are in descending order (placing | |
|
1356 | most time consuming items first), where as name, file, and line number | |
|
1357 | searches are in ascending order (i.e., alphabetical). The subtle | |
|
1358 | distinction between "nfl" and "stdname" is that the standard name is a | |
|
1359 | sort of the name as printed, which means that the embedded line | |
|
1360 | numbers get compared in an odd way. For example, lines 3, 20, and 40 | |
|
1361 | would (if the file names were the same) appear in the string order | |
|
1362 | "20" "3" and "40". In contrast, "nfl" does a numeric compare of the | |
|
1363 | line numbers. In fact, sort_stats("nfl") is the same as | |
|
1364 | sort_stats("name", "file", "line"). | |
|
1365 | ||
|
1366 | -T <filename>: save profile results as shown on screen to a text | |
|
1367 | file. The profile is still shown on screen. | |
|
1368 | ||
|
1369 | -D <filename>: save (via dump_stats) profile statistics to given | |
|
1370 | filename. This data is in a format understod by the pstats module, and | |
|
1371 | is generated by a call to the dump_stats() method of profile | |
|
1372 | objects. The profile is still shown on screen. | |
|
1373 | ||
|
1374 | If you want to run complete programs under the profiler's control, use | |
|
1375 | '%run -p [prof_opts] filename.py [args to program]' where prof_opts | |
|
1376 | contains profiler specific options as described here. | |
|
1377 | ||
|
1378 | You can read the complete documentation for the profile module with:\ | |
|
1379 | In [1]: import profile; profile.help() | |
|
1380 | ||
|
1381 | **%psearch**:: | |
|
1382 | ||
|
1383 | Search for object in namespaces by wildcard. | |
|
1384 | ||
|
1385 | %psearch [options] PATTERN [OBJECT TYPE] | |
|
1386 | ||
|
1387 | Note: ? can be used as a synonym for %psearch, at the beginning or at | |
|
1388 | the end: both a*? and ?a* are equivalent to '%psearch a*'. Still, the | |
|
1389 | rest of the command line must be unchanged (options come first), so | |
|
1390 | for example the following forms are equivalent | |
|
1391 | ||
|
1392 | %psearch -i a* function | |
|
1393 | -i a* function? | |
|
1394 | ?-i a* function | |
|
1395 | ||
|
1396 | Arguments: | |
|
1397 | ||
|
1398 | PATTERN | |
|
1399 | ||
|
1400 | where PATTERN is a string containing * as a wildcard similar to its | |
|
1401 | use in a shell. The pattern is matched in all namespaces on the | |
|
1402 | search path. By default objects starting with a single _ are not | |
|
1403 | matched, many IPython generated objects have a single | |
|
1404 | underscore. The default is case insensitive matching. Matching is | |
|
1405 | also done on the attributes of objects and not only on the objects | |
|
1406 | in a module. | |
|
1407 | ||
|
1408 | [OBJECT TYPE] | |
|
1409 | ||
|
1410 | Is the name of a python type from the types module. The name is | |
|
1411 | given in lowercase without the ending type, ex. StringType is | |
|
1412 | written string. By adding a type here only objects matching the | |
|
1413 | given type are matched. Using all here makes the pattern match all | |
|
1414 | types (this is the default). | |
|
1415 | ||
|
1416 | Options: | |
|
1417 | ||
|
1418 | -a: makes the pattern match even objects whose names start with a | |
|
1419 | single underscore. These names are normally ommitted from the | |
|
1420 | search. | |
|
1421 | ||
|
1422 | -i/-c: make the pattern case insensitive/sensitive. If neither of | |
|
1423 | these options is given, the default is read from your ipythonrc | |
|
1424 | file. The option name which sets this value is | |
|
1425 | 'wildcards_case_sensitive'. If this option is not specified in your | |
|
1426 | ipythonrc file, IPython's internal default is to do a case sensitive | |
|
1427 | search. | |
|
1428 | ||
|
1429 | -e/-s NAMESPACE: exclude/search a given namespace. The pattern you | |
|
1430 | specifiy can be searched in any of the following namespaces: | |
|
1431 | 'builtin', 'user', 'user_global','internal', 'alias', where | |
|
1432 | 'builtin' and 'user' are the search defaults. Note that you should | |
|
1433 | not use quotes when specifying namespaces. | |
|
1434 | ||
|
1435 | 'Builtin' contains the python module builtin, 'user' contains all | |
|
1436 | user data, 'alias' only contain the shell aliases and no python | |
|
1437 | objects, 'internal' contains objects used by IPython. The | |
|
1438 | 'user_global' namespace is only used by embedded IPython instances, | |
|
1439 | and it contains module-level globals. You can add namespaces to the | |
|
1440 | search with -s or exclude them with -e (these options can be given | |
|
1441 | more than once). | |
|
1442 | ||
|
1443 | Examples: | |
|
1444 | ||
|
1445 | %psearch a* -> objects beginning with an a | |
|
1446 | %psearch -e builtin a* -> objects NOT in the builtin space starting in a | |
|
1447 | %psearch a* function -> all functions beginning with an a | |
|
1448 | %psearch re.e* -> objects beginning with an e in module re | |
|
1449 | %psearch r*.e* -> objects that start with e in modules starting in r | |
|
1450 | %psearch r*.* string -> all strings in modules beginning with r | |
|
1451 | ||
|
1452 | Case sensitve search: | |
|
1453 | ||
|
1454 | %psearch -c a* list all object beginning with lower case a | |
|
1455 | ||
|
1456 | Show objects beginning with a single _: | |
|
1457 | ||
|
1458 | %psearch -a _* list objects beginning with a single underscore | |
|
1459 | ||
|
1460 | **%psource**:: | |
|
1461 | ||
|
1462 | Print (or run through pager) the source code for an object. | |
|
1463 | ||
|
1464 | **%pushd**:: | |
|
1465 | ||
|
1466 | Place the current dir on stack and change directory. | |
|
1467 | ||
|
1468 | Usage:\ | |
|
1469 | %pushd ['dirname'] | |
|
1470 | ||
|
1471 | **%pwd**:: | |
|
1472 | ||
|
1473 | Return the current working directory path. | |
|
1474 | ||
|
1475 | **%pycat**:: | |
|
1476 | ||
|
1477 | Show a syntax-highlighted file through a pager. | |
|
1478 | ||
|
1479 | This magic is similar to the cat utility, but it will assume the file | |
|
1480 | to be Python source and will show it with syntax highlighting. | |
|
1481 | ||
|
1482 | **%quickref**:: | |
|
1483 | ||
|
1484 | Show a quick reference sheet | |
|
1485 | ||
|
1486 | **%quit**:: | |
|
1487 | ||
|
1488 | Exit IPython, confirming if configured to do so (like %exit) | |
|
1489 | ||
|
1490 | **%r**:: | |
|
1491 | ||
|
1492 | Repeat previous input. | |
|
1493 | ||
|
1494 | Note: Consider using the more powerfull %rep instead! | |
|
1495 | ||
|
1496 | If given an argument, repeats the previous command which starts with | |
|
1497 | the same string, otherwise it just repeats the previous input. | |
|
1498 | ||
|
1499 | Shell escaped commands (with ! as first character) are not recognized | |
|
1500 | by this system, only pure python code and magic commands. | |
|
1501 | ||
|
1502 | **%rehashdir**:: | |
|
1503 | ||
|
1504 | Add executables in all specified dirs to alias table | |
|
1505 | ||
|
1506 | Usage: | |
|
1507 | ||
|
1508 | %rehashdir c:/bin;c:/tools | |
|
1509 | - Add all executables under c:/bin and c:/tools to alias table, in | |
|
1510 | order to make them directly executable from any directory. | |
|
1511 | ||
|
1512 | Without arguments, add all executables in current directory. | |
|
1513 | ||
|
1514 | **%rehashx**:: | |
|
1515 | ||
|
1516 | Update the alias table with all executable files in $PATH. | |
|
1517 | ||
|
1518 | This version explicitly checks that every entry in $PATH is a file | |
|
1519 | with execute access (os.X_OK), so it is much slower than %rehash. | |
|
1520 | ||
|
1521 | Under Windows, it checks executability as a match agains a | |
|
1522 | '|'-separated string of extensions, stored in the IPython config | |
|
1523 | variable win_exec_ext. This defaults to 'exe|com|bat'. | |
|
1524 | ||
|
1525 | This function also resets the root module cache of module completer, | |
|
1526 | used on slow filesystems. | |
|
1527 | ||
|
1528 | **%rep**:: | |
|
1529 | ||
|
1530 | Repeat a command, or get command to input line for editing | |
|
1531 | ||
|
1532 | - %rep (no arguments): | |
|
1533 | ||
|
1534 | Place a string version of last computation result (stored in the special '_' | |
|
1535 | variable) to the next input prompt. Allows you to create elaborate command | |
|
1536 | lines without using copy-paste:: | |
|
1537 | ||
|
1538 | $ l = ["hei", "vaan"] | |
|
1539 | $ "".join(l) | |
|
1540 | ==> heivaan | |
|
1541 | $ %rep | |
|
1542 | $ heivaan_ <== cursor blinking | |
|
1543 | ||
|
1544 | %rep 45 | |
|
1545 | ||
|
1546 | Place history line 45 to next input prompt. Use %hist to find out the | |
|
1547 | number. | |
|
1548 | ||
|
1549 | %rep 1-4 6-7 3 | |
|
1550 | ||
|
1551 | Repeat the specified lines immediately. Input slice syntax is the same as | |
|
1552 | in %macro and %save. | |
|
1553 | ||
|
1554 | %rep foo | |
|
1555 | ||
|
1556 | Place the most recent line that has the substring "foo" to next input. | |
|
1557 | (e.g. 'svn ci -m foobar'). | |
|
1558 | ||
|
1559 | **%reset**:: | |
|
1560 | ||
|
1561 | Resets the namespace by removing all names defined by the user. | |
|
1562 | ||
|
1563 | Input/Output history are left around in case you need them. | |
|
1564 | ||
|
1565 | **%run**:: | |
|
1566 | ||
|
1567 | Run the named file inside IPython as a program. | |
|
1568 | ||
|
1569 | Usage:\ | |
|
1570 | %run [-n -i -t [-N<N>] -d [-b<N>] -p [profile options]] file [args] | |
|
1571 | ||
|
1572 | Parameters after the filename are passed as command-line arguments to | |
|
1573 | the program (put in sys.argv). Then, control returns to IPython's | |
|
1574 | prompt. | |
|
1575 | ||
|
1576 | This is similar to running at a system prompt:\ | |
|
1577 | $ python file args\ | |
|
1578 | but with the advantage of giving you IPython's tracebacks, and of | |
|
1579 | loading all variables into your interactive namespace for further use | |
|
1580 | (unless -p is used, see below). | |
|
1581 | ||
|
1582 | The file is executed in a namespace initially consisting only of | |
|
1583 | __name__=='__main__' and sys.argv constructed as indicated. It thus | |
|
1584 | sees its environment as if it were being run as a stand-alone program | |
|
1585 | (except for sharing global objects such as previously imported | |
|
1586 | modules). But after execution, the IPython interactive namespace gets | |
|
1587 | updated with all variables defined in the program (except for __name__ | |
|
1588 | and sys.argv). This allows for very convenient loading of code for | |
|
1589 | interactive work, while giving each program a 'clean sheet' to run in. | |
|
1590 | ||
|
1591 | Options: | |
|
1592 | ||
|
1593 | -n: __name__ is NOT set to '__main__', but to the running file's name | |
|
1594 | without extension (as python does under import). This allows running | |
|
1595 | scripts and reloading the definitions in them without calling code | |
|
1596 | protected by an ' if __name__ == "__main__" ' clause. | |
|
1597 | ||
|
1598 | -i: run the file in IPython's namespace instead of an empty one. This | |
|
1599 | is useful if you are experimenting with code written in a text editor | |
|
1600 | which depends on variables defined interactively. | |
|
1601 | ||
|
1602 | -e: ignore sys.exit() calls or SystemExit exceptions in the script | |
|
1603 | being run. This is particularly useful if IPython is being used to | |
|
1604 | run unittests, which always exit with a sys.exit() call. In such | |
|
1605 | cases you are interested in the output of the test results, not in | |
|
1606 | seeing a traceback of the unittest module. | |
|
1607 | ||
|
1608 | -t: print timing information at the end of the run. IPython will give | |
|
1609 | you an estimated CPU time consumption for your script, which under | |
|
1610 | Unix uses the resource module to avoid the wraparound problems of | |
|
1611 | time.clock(). Under Unix, an estimate of time spent on system tasks | |
|
1612 | is also given (for Windows platforms this is reported as 0.0). | |
|
1613 | ||
|
1614 | If -t is given, an additional -N<N> option can be given, where <N> | |
|
1615 | must be an integer indicating how many times you want the script to | |
|
1616 | run. The final timing report will include total and per run results. | |
|
1617 | ||
|
1618 | For example (testing the script uniq_stable.py): | |
|
1619 | ||
|
1620 | In [1]: run -t uniq_stable | |
|
1621 | ||
|
1622 | IPython CPU timings (estimated):\ | |
|
1623 | User : 0.19597 s.\ | |
|
1624 | System: 0.0 s.\ | |
|
1625 | ||
|
1626 | In [2]: run -t -N5 uniq_stable | |
|
1627 | ||
|
1628 | IPython CPU timings (estimated):\ | |
|
1629 | Total runs performed: 5\ | |
|
1630 | Times : Total Per run\ | |
|
1631 | User : 0.910862 s, 0.1821724 s.\ | |
|
1632 | System: 0.0 s, 0.0 s. | |
|
1633 | ||
|
1634 | -d: run your program under the control of pdb, the Python debugger. | |
|
1635 | This allows you to execute your program step by step, watch variables, | |
|
1636 | etc. Internally, what IPython does is similar to calling: | |
|
1637 | ||
|
1638 | pdb.run('execfile("YOURFILENAME")') | |
|
1639 | ||
|
1640 | with a breakpoint set on line 1 of your file. You can change the line | |
|
1641 | number for this automatic breakpoint to be <N> by using the -bN option | |
|
1642 | (where N must be an integer). For example: | |
|
1643 | ||
|
1644 | %run -d -b40 myscript | |
|
1645 | ||
|
1646 | will set the first breakpoint at line 40 in myscript.py. Note that | |
|
1647 | the first breakpoint must be set on a line which actually does | |
|
1648 | something (not a comment or docstring) for it to stop execution. | |
|
1649 | ||
|
1650 | When the pdb debugger starts, you will see a (Pdb) prompt. You must | |
|
1651 | first enter 'c' (without qoutes) to start execution up to the first | |
|
1652 | breakpoint. | |
|
1653 | ||
|
1654 | Entering 'help' gives information about the use of the debugger. You | |
|
1655 | can easily see pdb's full documentation with "import pdb;pdb.help()" | |
|
1656 | at a prompt. | |
|
1657 | ||
|
1658 | -p: run program under the control of the Python profiler module (which | |
|
1659 | prints a detailed report of execution times, function calls, etc). | |
|
1660 | ||
|
1661 | You can pass other options after -p which affect the behavior of the | |
|
1662 | profiler itself. See the docs for %prun for details. | |
|
1663 | ||
|
1664 | In this mode, the program's variables do NOT propagate back to the | |
|
1665 | IPython interactive namespace (because they remain in the namespace | |
|
1666 | where the profiler executes them). | |
|
1667 | ||
|
1668 | Internally this triggers a call to %prun, see its documentation for | |
|
1669 | details on the options available specifically for profiling. | |
|
1670 | ||
|
1671 | There is one special usage for which the text above doesn't apply: | |
|
1672 | if the filename ends with .ipy, the file is run as ipython script, | |
|
1673 | just as if the commands were written on IPython prompt. | |
|
1674 | ||
|
1675 | **%runlog**:: | |
|
1676 | ||
|
1677 | Run files as logs. | |
|
1678 | ||
|
1679 | Usage:\ | |
|
1680 | %runlog file1 file2 ... | |
|
1681 | ||
|
1682 | Run the named files (treating them as log files) in sequence inside | |
|
1683 | the interpreter, and return to the prompt. This is much slower than | |
|
1684 | %run because each line is executed in a try/except block, but it | |
|
1685 | allows running files with syntax errors in them. | |
|
1686 | ||
|
1687 | Normally IPython will guess when a file is one of its own logfiles, so | |
|
1688 | you can typically use %run even for logs. This shorthand allows you to | |
|
1689 | force any file to be treated as a log file. | |
|
1690 | ||
|
1691 | **%save**:: | |
|
1692 | ||
|
1693 | Save a set of lines to a given filename. | |
|
1694 | ||
|
1695 | Usage:\ | |
|
1696 | %save [options] filename n1-n2 n3-n4 ... n5 .. n6 ... | |
|
1697 | ||
|
1698 | Options: | |
|
1699 | ||
|
1700 | -r: use 'raw' input. By default, the 'processed' history is used, | |
|
1701 | so that magics are loaded in their transformed version to valid | |
|
1702 | Python. If this option is given, the raw input as typed as the | |
|
1703 | command line is used instead. | |
|
1704 | ||
|
1705 | This function uses the same syntax as %macro for line extraction, but | |
|
1706 | instead of creating a macro it saves the resulting string to the | |
|
1707 | filename you specify. | |
|
1708 | ||
|
1709 | It adds a '.py' extension to the file if you don't do so yourself, and | |
|
1710 | it asks for confirmation before overwriting existing files. | |
|
1711 | ||
|
1712 | **%sc**:: | |
|
1713 | ||
|
1714 | Shell capture - execute a shell command and capture its output. | |
|
1715 | ||
|
1716 | DEPRECATED. Suboptimal, retained for backwards compatibility. | |
|
1717 | ||
|
1718 | You should use the form 'var = !command' instead. Example: | |
|
1719 | ||
|
1720 | "%sc -l myfiles = ls ~" should now be written as | |
|
1721 | ||
|
1722 | "myfiles = !ls ~" | |
|
1723 | ||
|
1724 | myfiles.s, myfiles.l and myfiles.n still apply as documented | |
|
1725 | below. | |
|
1726 | ||
|
1727 | -- | |
|
1728 | %sc [options] varname=command | |
|
1729 | ||
|
1730 | IPython will run the given command using commands.getoutput(), and | |
|
1731 | will then update the user's interactive namespace with a variable | |
|
1732 | called varname, containing the value of the call. Your command can | |
|
1733 | contain shell wildcards, pipes, etc. | |
|
1734 | ||
|
1735 | The '=' sign in the syntax is mandatory, and the variable name you | |
|
1736 | supply must follow Python's standard conventions for valid names. | |
|
1737 | ||
|
1738 | (A special format without variable name exists for internal use) | |
|
1739 | ||
|
1740 | Options: | |
|
1741 | ||
|
1742 | -l: list output. Split the output on newlines into a list before | |
|
1743 | assigning it to the given variable. By default the output is stored | |
|
1744 | as a single string. | |
|
1745 | ||
|
1746 | -v: verbose. Print the contents of the variable. | |
|
1747 | ||
|
1748 | In most cases you should not need to split as a list, because the | |
|
1749 | returned value is a special type of string which can automatically | |
|
1750 | provide its contents either as a list (split on newlines) or as a | |
|
1751 | space-separated string. These are convenient, respectively, either | |
|
1752 | for sequential processing or to be passed to a shell command. | |
|
1753 | ||
|
1754 | For example: | |
|
1755 | ||
|
1756 | # Capture into variable a | |
|
1757 | In [9]: sc a=ls *py | |
|
1758 | ||
|
1759 | # a is a string with embedded newlines | |
|
1760 | In [10]: a | |
|
1761 | Out[10]: 'setup.py win32_manual_post_install.py' | |
|
1762 | ||
|
1763 | # which can be seen as a list: | |
|
1764 | In [11]: a.l | |
|
1765 | Out[11]: ['setup.py', 'win32_manual_post_install.py'] | |
|
1766 | ||
|
1767 | # or as a whitespace-separated string: | |
|
1768 | In [12]: a.s | |
|
1769 | Out[12]: 'setup.py win32_manual_post_install.py' | |
|
1770 | ||
|
1771 | # a.s is useful to pass as a single command line: | |
|
1772 | In [13]: !wc -l $a.s | |
|
1773 | 146 setup.py | |
|
1774 | 130 win32_manual_post_install.py | |
|
1775 | 276 total | |
|
1776 | ||
|
1777 | # while the list form is useful to loop over: | |
|
1778 | In [14]: for f in a.l: | |
|
1779 | ....: !wc -l $f | |
|
1780 | ....: | |
|
1781 | 146 setup.py | |
|
1782 | 130 win32_manual_post_install.py | |
|
1783 | ||
|
1784 | Similiarly, the lists returned by the -l option are also special, in | |
|
1785 | the sense that you can equally invoke the .s attribute on them to | |
|
1786 | automatically get a whitespace-separated string from their contents: | |
|
1787 | ||
|
1788 | In [1]: sc -l b=ls *py | |
|
1789 | ||
|
1790 | In [2]: b | |
|
1791 | Out[2]: ['setup.py', 'win32_manual_post_install.py'] | |
|
1792 | ||
|
1793 | In [3]: b.s | |
|
1794 | Out[3]: 'setup.py win32_manual_post_install.py' | |
|
1795 | ||
|
1796 | In summary, both the lists and strings used for ouptut capture have | |
|
1797 | the following special attributes: | |
|
1798 | ||
|
1799 | .l (or .list) : value as list. | |
|
1800 | .n (or .nlstr): value as newline-separated string. | |
|
1801 | .s (or .spstr): value as space-separated string. | |
|
1802 | ||
|
1803 | **%store**:: | |
|
1804 | ||
|
1805 | Lightweight persistence for python variables. | |
|
1806 | ||
|
1807 | Example: | |
|
1808 | ||
|
1809 | ville@badger[~]|1> A = ['hello',10,'world']\ | |
|
1810 | ville@badger[~]|2> %store A\ | |
|
1811 | ville@badger[~]|3> Exit | |
|
1812 | ||
|
1813 | (IPython session is closed and started again...) | |
|

1816 | ville@badger[~]|1> print A | |
|
1817 | ||
|
1818 | ['hello', 10, 'world'] | |
|
1819 | ||
|
1820 | Usage: | |
|
1821 | ||
|
1822 | %store - Show list of all variables and their current values\ | |
|
1823 | %store <var> - Store the *current* value of the variable to disk\ | |
|
1824 | %store -d <var> - Remove the variable and its value from storage\ | |
|
1825 | %store -z - Remove all variables from storage\ | |
|
1826 | %store -r - Refresh all variables from store (delete current vals)\ | |
|
1827 | %store foo >a.txt - Store value of foo to new file a.txt\ | |
|
1828 | %store foo >>a.txt - Append value of foo to file a.txt\ | |
|
1829 | ||
|
1830 | It should be noted that if you change the value of a variable, you | |
|
1831 | need to %store it again if you want to persist the new value. | |
|
1832 | ||
|
1833 | Note also that the variables will need to be pickleable; most basic | |
|
1834 | python types can be safely %stored. | |
|
1835 | ||
|
1836 | Also aliases can be %store'd across sessions. | |
|
1837 | ||
|
1838 | **%sx**:: | |
|
1839 | ||
|
1840 | Shell execute - run a shell command and capture its output. | |
|
1841 | ||
|
1842 | %sx command | |
|
1843 | ||
|
1844 | IPython will run the given command using commands.getoutput(), and | |
|
1845 | return the result formatted as a list (split on '\n'). Since the | |
|
1846 | output is _returned_, it will be stored in ipython's regular output | |
|
1847 | cache Out[N] and in the '_N' automatic variables. | |
|
1848 | ||
|
1849 | Notes: | |
|
1850 | ||
|
1851 | 1) If an input line begins with '!!', then %sx is automatically | |
|
1852 | invoked. That is, while: | |
|
1853 | !ls | |
|
1854 | causes ipython to simply issue system('ls'), typing | |
|
1855 | !!ls | |
|
1856 | is a shorthand equivalent to: | |
|
1857 | %sx ls | |
|
1858 | ||
|
1859 | 2) %sx differs from %sc in that %sx automatically splits into a list, | |
|
1860 | like '%sc -l'. The reason for this is to make it as easy as possible | |
|
1861 | to process line-oriented shell output via further python commands. | |
|
1862 | %sc is meant to provide much finer control, but requires more | |
|
1863 | typing. | |
|
1864 | ||
|
1865 | 3) Just like %sc -l, this is a list with special attributes: | |
|
1866 | ||
|
1867 | .l (or .list) : value as list. | |
|
1868 | .n (or .nlstr): value as newline-separated string. | |
|
1869 | .s (or .spstr): value as whitespace-separated string. | |
|
1870 | ||
|
1871 | This is very useful when trying to use such lists as arguments to | |
|
1872 | system commands. | |
|
1873 | ||
|
1874 | **%system_verbose**:: | |
|
1875 | ||
|
1876 | Set verbose printing of system calls. | |
|
1877 | ||
|
1878 | If called without an argument, act as a toggle | |
|
1879 | ||
|
1880 | **%time**:: | |
|
1881 | ||
|
1882 | Time execution of a Python statement or expression. | |
|
1883 | ||
|
1884 | The CPU and wall clock times are printed, and the value of the | |
|
1885 | expression (if any) is returned. Note that under Win32, system time | |
|
1886 | is always reported as 0, since it can not be measured. | |
|
1887 | ||
|
1888 | This function provides very basic timing functionality. In Python | |
|
1889 | 2.3, the timeit module offers more control and sophistication, so this | |
|
1890 | could be rewritten to use it (patches welcome). | |
|
1891 | ||
|
1892 | Some examples: | |
|
1893 | ||
|
1894 | In [1]: time 2**128 | |
|
1895 | CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s | |
|
1896 | Wall time: 0.00 | |
|
1897 | Out[1]: 340282366920938463463374607431768211456L | |
|
1898 | ||
|
1899 | In [2]: n = 1000000 | |
|
1900 | ||
|
1901 | In [3]: time sum(range(n)) | |
|
1902 | CPU times: user 1.20 s, sys: 0.05 s, total: 1.25 s | |
|
1903 | Wall time: 1.37 | |
|
1904 | Out[3]: 499999500000L | |
|
1905 | ||
|
1906 | In [4]: time print 'hello world' | |
|
1907 | hello world | |
|
1908 | CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s | |
|
1909 | Wall time: 0.00 | |
|
1910 | ||
|
1911 | Note that the time needed by Python to compile the given expression | |
|
1912 | will be reported if it is more than 0.1s. In this example, the | |
|
1913 | actual exponentiation is done by Python at compilation time, so while | |
|
1914 | the expression can take a noticeable amount of time to compute, that | |
|
1915 | time is purely due to the compilation: | |
|
1916 | ||
|
1917 | In [5]: time 3**9999; | |
|
1918 | CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s | |
|
1919 | Wall time: 0.00 s | |
|
1920 | ||
|
1921 | In [6]: time 3**999999; | |
|
1922 | CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s | |
|
1923 | Wall time: 0.00 s | |
|
1924 | Compiler : 0.78 s | |
|
1925 | ||
|
1926 | **%timeit**:: | |
|
1927 | ||
|
1928 | Time execution of a Python statement or expression | |
|
1929 | ||
|
1930 | Usage:\ | |
|
1931 | %timeit [-n<N> -r<R> [-t|-c]] statement | |
|
1932 | ||
|
1933 | Time execution of a Python statement or expression using the timeit | |
|
1934 | module. | |
|
1935 | ||
|
1936 | Options: | |
|
1937 | -n<N>: execute the given statement <N> times in a loop. If this value | |
|
1938 | is not given, a fitting value is chosen. | |
|
1939 | ||
|
1940 | -r<R>: repeat the loop iteration <R> times and take the best result. | |
|
1941 | Default: 3 | |
|
1942 | ||
|
1943 | -t: use time.time to measure the time, which is the default on Unix. | |
|
1944 | This function measures wall time. | |
|
1945 | ||
|
1946 | -c: use time.clock to measure the time, which is the default on | |
|
1947 | Windows and measures wall time. On Unix, resource.getrusage is used | |
|
1948 | instead and returns the CPU user time. | |
|
1949 | ||
|
1950 | -p<P>: use a precision of <P> digits to display the timing result. | |
|
1951 | Default: 3 | |
|
1952 | ||
|
1953 | ||
|
1954 | Examples:\ | |
|
1955 | In [1]: %timeit pass | |
|
1956 | 10000000 loops, best of 3: 53.3 ns per loop | |
|
1957 | ||
|
1958 | In [2]: u = None | |
|
1959 | ||
|
1960 | In [3]: %timeit u is None | |
|
1961 | 10000000 loops, best of 3: 184 ns per loop | |
|
1962 | ||
|
1963 | In [4]: %timeit -r 4 u == None | |
|
1964 | 1000000 loops, best of 4: 242 ns per loop | |
|
1965 | ||
|
1966 | In [5]: import time | |
|
1967 | ||
|
1968 | In [6]: %timeit -n1 time.sleep(2) | |
|
1969 | 1 loops, best of 3: 2 s per loop | |
|
1970 | ||
|
1971 | ||
|
1972 | The times reported by %timeit will be slightly higher than those | |
|
1973 | reported by the timeit.py script when variables are accessed. This is | |
|
1974 | due to the fact that %timeit executes the statement in the namespace | |
|
1975 | of the shell, compared with timeit.py, which uses a single setup | |
|
1976 | statement to import function or create variables. Generally, the bias | |
|
1977 | does not matter as long as results from timeit.py are not mixed with | |
|
1978 | those from %timeit. | |
|
1979 | ||
|
1980 | **%unalias**:: | |
|
1981 | ||
|
1982 | Remove an alias | |
|
1983 | ||
|
1984 | **%upgrade**:: | |
|
1985 | ||
|
1986 | Upgrade your IPython installation | |
|
1987 | ||
|
1988 | This will copy the config files that don't yet exist in your | |
|
1989 | ipython dir from the system config dir. Use this after upgrading | |
|
1990 | IPython if you don't wish to delete your .ipython dir. | |
|
1991 | ||
|
1992 | Call with -nolegacy to get rid of ipythonrc* files (recommended for | |
|
1993 | new users) | |
|
1994 | ||
|
1995 | **%which**:: | |
|
1996 | ||
|
1997 | %which <cmd> => search PATH for files matching cmd. Also scans aliases. | |
|
1998 | ||
|
1999 | Traverses PATH and prints all files (not just executables!) that match the | |
|
2000 | pattern on command line. Probably more useful in finding stuff | |
|
2001 | interactively than 'which', which only prints the first matching item. | |
|
2002 | ||
|
2003 | Also discovers and expands aliases, so you'll see what will be executed | |
|
2004 | when you call an alias. | |
|
2005 | ||
|
2006 | Example: | |
|
2007 | ||
|
2008 | [~]|62> %which d | |
|
2009 | d -> ls -F --color=auto | |
|
2010 | == c:\cygwin\bin\ls.exe | |
|
2011 | c:\cygwin\bin\d.exe | |
|
2012 | ||
|
2013 | [~]|64> %which diff* | |
|
2014 | diff3 -> diff3 | |
|
2015 | == c:\cygwin\bin\diff3.exe | |
|
2016 | diff -> diff | |
|
2017 | == c:\cygwin\bin\diff.exe | |
|
2018 | c:\cygwin\bin\diff.exe | |
|
2019 | c:\cygwin\bin\diff3.exe | |
|
2020 | ||
|
2021 | **%who**:: | |
|
2022 | ||
|
2023 | Print all interactive variables, with some minimal formatting. | |
|
2024 | ||
|
2025 | If any arguments are given, only variables whose type matches one of | |
|
2026 | these are printed. For example: | |
|
2027 | ||
|
2028 | %who function str | |
|
2029 | ||
|
2030 | will only list functions and strings, excluding all other types of | |
|
2031 | variables. To find the proper type names, simply use type(var) at a | |
|
2032 | command line to see how python prints type names. For example: | |
|
2033 | ||
|
2034 | In [1]: type('hello')\ | |
|
2035 | Out[1]: <type 'str'> | |
|
2036 | ||
|
2037 | indicates that the type name for strings is 'str'. | |
|
2038 | ||
|
2039 | %who always excludes executed names loaded through your configuration | |
|
2040 | file and things which are internal to IPython. | |
|
2041 | ||
|
2042 | This is deliberate, as typically you may load many modules and the | |
|
2043 | purpose of %who is to show you only what you've manually defined. | |
|
2044 | ||
|
2045 | **%who_ls**:: | |
|
2046 | ||
|
2047 | Return a sorted list of all interactive variables. | |
|
2048 | ||
|
2049 | If arguments are given, only variables of types matching these | |
|
2050 | arguments are returned. | |
|
2051 | ||
|
2052 | **%whos**:: | |
|
2053 | ||
|
2054 | Like %who, but gives some extra information about each variable. | |
|
2055 | ||
|
2056 | The same type filtering of %who can be applied here. | |
|
2057 | ||
|
2058 | For all variables, the type is printed. Additionally it prints: | |
|
2059 | ||
|
2060 | - For {},[],(): their length. | |
|
2061 | ||
|
2062 | - For numpy and Numeric arrays, a summary with shape, number of | |
|
2063 | elements, typecode and size in memory. | |
|
2064 | ||
|
2065 | - Everything else: a string representation, snipping their middle if | |
|
2066 | too long. | |
|
2067 | ||
|
2068 | **%xmode**:: | |
|
2069 | ||
|
2070 | Switch modes for the exception handlers. | |
|
2071 | ||
|
2072 | Valid modes: Plain, Context and Verbose. | |
|
2073 | ||
|
2074 | If called without arguments, acts as a toggle. | |
