Calling to those "embedding" matplotlib in applications

I’m considering changing
the behavior of the rcParam interactive
(which also can be set through matplotlib.interactive()
and pyplot.ion()
and pyplot.ioff() ).
Currently, when setting interactive
to True ,
running any sort of matplotlib plot as a script will fail to
display a window. This can be very surprising if a user turns on
interactive
because they prefer its behavior in IPython, but are then
surprised that none of their scripts continue to work. I propose
to fix this by turning on interactive
only when running at an interactive console.

See the pull request http://github.com/matplotlib/matplotlib/pull/2286
for an implementation.

    I'm trying to rule out

any negative impact of this change, and I would appreciate any
feedback if this change will have a negative impact on your
application.

I embed MPL more than other uses, and this sounds like a fine solution to me/

Thanks,

Would you mind testing the very simple patch in the PR [1] and confirm that it has no negative consequences for you?

Hmm -- I'm not set up to build it right now -- but I'll see what I can do.

It appears bpython does not set sys.ps1. I wonder if this shouldn't
be considered a bug/oversight in bpython though. If nothing else it
might be worth pointing out to its developers. I also wonder how this
would impact IDEs (though I don't use any personally).

Apparently IDLE doesn't set sys.ps1 either:
http://bugs.python.org/issue13657 I know at least a few people who
use IDLE.... :wink:

I feel like there has to be a better way to determine if an
interactive prompt is in use, though I'll admit nothing jumps
immediately to mind :confused:

Maybe this is a good thing; interactive mode doesn't work in IDLE.
