[matplotlib-devel] Calling to those "embedding" matplotlib in applications

[Michael D. <md...@st...>]

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.... ;)

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 :/

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