It's at "technology demo" right now, but basic stuff like tab completion now works. The colors suck (typical ipython + white background issue), KeyboardInterrupt doesn't work (apart from doing it in the console window) and it probably has lots of other problems, but nothing that hasn't been solved in other gui's already, so it probably won't take forever to polish it. Input happens in separate scintilla widget, so it requires a bit of a mindset switch, but nothing too drastic. The big win is simplicity of multiline editing, and general "statelessness" (autoindent etc). You can test it out by doing: bzr branch lp:~villemvainio/ipython/ipython-qt-ui and running qtipy.py.

I'm on a linux machine and I'm wondering if is it possible to do something like: vim newfile.py Or at least using touch. Thanks.

Something like > ipython 'agg_oo.py --verbose-helpful' Which does not work. Is such a thing possible? If not, what is the proper incantation to add at the end of the script to open an interactive ipython shell with the namespace of the script? I tried:: from IPython.Shell import IPShellEmbed ipshell = IPShellEmbed() ipshell() but it did not like the command args either :-( Thanks, JDH IPython 0.9.0.bzr.r1016 John Hunter 2008-11-24T17:16:24 http://comments.gmane.org/gmane.comp.python.ipython.user/4150 Hello list, I am just beginning teaching myself IPython, and I am stumbling. Following the steps in a book on Computer Programming (Langtangen), the author gives the following example: In [1]: run ball_variables.py 1.2342 In [2]: _*10 Out[2]: 12.341999999999999 That is, he argues that with an underscore "_" the last result can be accessed. However, I cannot reproduce this behaviour. I am running Python 2.5.2 (r252:60911) with IPython 0.8.1. Could someone please be so kind and let me know what the mistake is? Cheers, David David 2008-11-22T16:02:31 http://comments.gmane.org/gmane.comp.python.ipython.user/4142 Hi, After a month or so of hacking on and off, I have finished a new version of the ipcluster script. This version has lots of new stuff: * Cross platform (Win32!) * Much more robust design (using Twisted) * Uses subcommands (ipcluster local, ipcluster pbs, etc.) for different cluster types. * Supports 3 cluster types currently (localhost, pbs, mpirun). The following just work: ipcluster local -n 4 ipcluster mpirun -n 16 --mpi-mpi4py ipcluster pbs -n 128 --pbs-script=pbs.template But, I am not sure how soon we want to merge this into trunk: * There are _no_ tests - this type of thing is very difficult to test. * No docs on this yet ( that is easy to fix). * The design is gong to change in massive ways - we need to refactor the config system in significant ways and that will change the API of ipcluster. * ipcluster itself needs some refactoring. It turns out that I will need to begin using Barry's notification center to really get the design right. But....

I have received a 10.5.5 MacBook Pro and am trying to get SciPy up and running again, with limited success. After installing Enthought, I lost the pydb support. When I execute with the -pydb option, I get an error message: $ ipython -pydb Pydb (http://bashdb.sourceforge.net/pydb/) does not seem to be available IPython 0.9.1 [on Py 2.5.2] That is the same version of ipython I had installed myself and the pydb support just worked. I abandoned the install from source because I could not install matplotlib successfully. However, I don't want to lose pydb. Any chance there is a way I can add pydb to the Enthought distribution? I have searched the internet and found no information on this topic.

Racine 2008-11-14T19:12:14 http://comments.gmane.org/gmane.comp.python.ipython.user/4130 Hi All, I've encountered a problem with the parallel capabilities in the new version of IPython 0.9.1. It seems that if you import a package in the MultiEngineClient then afterwards running tasks with the TaskClient fails. This use case was working properly in the previous version of IPython1. Attached is a reduced example that produces the error on my machine.

Once a specific version is downloaded, what would the equivalent of switching to a different tag in Subversion be? I'm used to doing this with Subversion and CVS but have no Bazaar-fu.

One of the main files that gets imported replaces sys.stdout with a class that does a few basic checks but is otherwise a very thin wrapper around sys.stdout. Problem is, as soon as I import the file my prompt gets hosed (I can see the raw ansi color codes, etc). Here is a stripped down version of the problem: In [1]: import sys class myout(): def __init__(self, fp): self.fp = fp def __getattr__(self, key): return getattr(self.fp, key) def close(self): self.fp.close() def write(self, s): self.fp.write(s) def flush(self): self.fp.flush() sys.stdout = myout(sys.stdout) ☺←[0;32m☻In [☺←[1;32m☻3☺←[0;32m☻]: ☺←[0m☻ I've looked through the IPython and pyreadline sources but I can't find anything obvious that would explain this. Does anyone have idea what the problem is or a David Shilvock 2008-11-13T06:07:22 http://comments.gmane.org/gmane.comp.python.ipython.user/4111 I am experiencing some unusual behavior *only* when I am directly working in the ipython shell. The problem involves the get method for a property. class MyClass(): def __init__(self): self._x = 3 def getx(self): print "getting x" return self._x def setx(x): print "setting x" self._x = x x = property(getx, setx) a = MyClass() a.x # prints "getting x" twice print a.x # prints "getting x" once If you stick all this in a file and do 'run test.py', the problem does not occur. Also, notice that it does not occur in the "print a.x" statement. Any thoughts as to why this is happening?

T J 2008-11-13T03:45:06 http://comments.gmane.org/gmane.comp.python.ipython.user/4106 Hi all, I was pointed at your wiki[1] page on TextMate integration, and decided it was such a great idea that I'd make it into a TextMate bundle. My aim is to get it put into the official bundle repository. To that end, I've set up a google group [2] for discussion, and made a start (by copying and pasting, with some tweaks) at a bundle on GitHub [3]. I currently maintain the Matlab/Octave bundle for TextMate, and I'm gradually moving towards using python instead. However, I'm a complete newbie to python and ipython/numpy/scipy so I'd like to ask for any comments, suggestions or help that anyone would like to give. In my view, a bundle wrapping all sorts of useful functionality (snippets/commands etc) for aiding scientific computing with python would be best, but since it was IPython functionality that inspired me to get started, I thought I'd ask you guys first. If there are any TextMate users out there who would like to see this functionality, or help out, then please join the google group.

Such initialization can be followed with non-trivial MapTasks. But my attempt to do so failed. The source code shows currently ipengine ignore every arg passed to it. Is there an easy way (other than via MultiEngineController) through it I can have engines executing customized init scripts or init python statement? I see some configuration can be down similarly to what "--mpi" option is doing, but not as strict forward as running a init scritpt like what Min has proposed: "ipengine -s init.py" Any suggestions will be highly appreciated.
