Re: start ipython from my own script

Unfortunately I don't know, but try to investigate what the --pylab
option really does and then there are maybe some kwarguments how to do
it. Or just patch ipython to do it and send a patch.

To all --- I am using the following combination quite often now:

import IPython
IPython.Shell.IPShell(user_ns=locals()).mainloop()

would it make sense to create something like:

import IPython
IPython.set_trace()

or something similar, that would just execute the above line?

Actually, to emulate pdb.set_trace(), I want to be able to access both
locals and globals, e.g. here is my line:

        IPython.Shell.IPShell(user_ns=dict(globals(), **locals())).mainloop()

I tried to implement this:

sys.exc_info() equivalent for ipython

Hello,

If I have a buggy file called foo.py and run it in Ipython using
   %run foo.py
ipython will print out an error message.  I would like to somehow save this error message.
Hence, I would like something similar to sys.exc_info() in iPython. 

Any tip?

Best,
Minjae

IPShellEmbed & listing interactive namespace?


Hello,

I would like to use IPShellEmbed to let users tinker with the internal state of my application.

After dropping them to the shell, what is the best way to give the users a list of currently available objects/names/modules?

%who does not seem to be working as expected, and locals() is littered with ipython internal stuff.

Thank you,
Allen

Re: IPShellEmbed & listing interactive namespace?

Hi,

Try these snippets and do a whos() in IPython:

import IPython
shell = IPython.Shell.IPShell(user_ns=locals())
a = 5
shell.mainloop()

Pushing proxy objects

Hi there,

I'm trying to set up remote visualization of data via the
MultiEngineClient interface, using matplotlib.  What I'd really like
to be able to do is to push across the network a proxy object for a
local set of axes and figure and then allow the remote engine to
interact with a local object.

For instance, something like the following in the controller session,
to put proxies for local figs and axes on the remote clients:

local_fig = pylab.gcf()
local_ax = pylab.gca()

mec = MultiEngineClient()
mec.push_proxy("fig", local_fig, [0])
mec.push_proxy("ax", local_fig, [0])
mec.execute("some_plotting_command(fig, ax)", [0])

This would enable something like local visualization via the wxAgg
backend, while the remote compute node wouldn't necessarily have to
handle any of the GUI interaction.  I believe that all of the standard
arguments for the OO API in matplotlib are pickleable, so passing
*those* across the network should work.  The return values would be
trickier, but I suppose some subset of objects for common plotting
commands could be identified that would auto-proxy rather than
attempting to pickle, say, subplot axes.

Is something like this already possible with the IPython parallel
engine?  If not, any suggestions on where to start out?

Thanks very much!  As a side note, the IPython ipengine interface has
been great and very easy to set up and use for parallel analysis of
data.

-Matt

Re: IPShellEmbed & listing interactive namespace?

Hello,

Thank you for the help.

A question:

What does this code work:

import IPython
shell = IPython.Shell.IPShell(user_ns=locals())
import app_modules
#And lot's of other setup
a = 5
shell.mainloop()

And this code does not:

import app_modules
#And lot's of other setup
# (Before creating shell)
import IPython
shell = IPython.Shell.IPShell(user_ns=locals())
a = 5
shell.mainloop()

Because in the second case imports will not be visible to IPython. Can you exit() from IPython using that method? I say 'y' but it doesn't let me exit, very interesting :)

Change prompt during IPython session

Hi All:
I want to change the behavior of my prompt during the ipython session.

Is it possible do it in a simple way?

something like:

from IPython.Prompts import Prompt1
prompt = Promtp1(cache, sep='\n', prompt=r'MyPromp [\#]: ', pad_left=True)

Regards!
