isympy doesn't work with the upcoming IPython v0.11

Hello,

I can't get the isympy working with the Fernando's trunk. I solved one
of
the missing attribute error but stuck at the other one:

[gsever@ccn bin]$ ./isympy
Traceback (most recent call last):
File "./isympy", line 153, in <module>
main()
File "./isympy", line 147, in main

__init__.py", line
97, in init_session
ip = IPython.ipapi.get()
AttributeError: 'module' object has no attribute 'ipapi'

[gsever@ccn bin]$ ./isympy

OK. We need to fix isympy. Could you push the fixes you were able to make up to github or somewhere? I can't get this error, but rather some NameError, assumedly because it is the issue you already fixed.

On the other hand, I am probably testing it wrong. How did you test the latest iPython? Did you have to install the development ipython, or is there some other way to do it? This is what I tried:

dhcp-baca-43:sympy aaronmeurer(master$)$../../ipython/ipython.py bin/isympy

Here are the steps:

bzr branch lp:~fdo.perez/ipython/trunk-dev
python setup.py install

git clone git://git.sympy.org/sympy.git
python setup.py install

(I like the variety, bzr for IPython, git for sympy, svn for numpy,
scipy, matplotlib, mercurial for SAGE, what else :)

These are my changes so far:

[gsever@ccn sympy]$ git diff

There is a substantial API change in the upcoming IPython (v0.11).
Fernando has been calling for test and integration test help. This
might be a good time to figure the issues from the Sympy's window.

Right. I'd rather not install python 11, especially considering that sympy does not work with it yet. Do you know how to test it without installing it?

This patch breaks the current iPython. We will probably want to maintain support for both, at least for a little while, so whatever fix we do will have to do version checking.

By the way, what is the timeline for iPython 0.11?

I opened an issue for this: http://code.google.com/p/sympy/issues/detail?id=1797

Hello all,

I just made an IPython ticket to make sure we (the IPython dev team) fix isympy before 0.11 is released:

https://bugs.launchpad.net/ipython/+bug/512123

In the meantime if you are using IPython trunk, you can do:

ipython -p sympy

To get the same effect.

Cheers,

Brian

By the way, what is the timeline for iPython 0.11?

We are hoping to have a release candidate in the next few weeks.  But, because it is such a major release, it will be a long release process.

Cheers,

Brian

You can run it without making any installation as well. Just do python
ipython.py, likewise you can execute the tests with python iptest.py
(You might need to install some external packages to fully execute the
test suite depending on your system.)

That's what I was thinking of. To do checks for v0.11 upwards and
before...

Should be coming out soon. Fernando was calling for tests recently.
Once his review merged in and some major bugs fixed it should be out.

Thanks. I am looking forward for the new release. My favourite new
feature is "IPython.embed()", I am using it all the time.
