Bummer. This happened in IPython on git master, display.line_width set to 80

It's not breaking the line?

I can't seem to repro on OSX or Ubuntu; i have line_width set to 80

I'm able to reproduce it but not using the above example. i'll dig to figure out what's up

OK the IPython check is failing for me:

In [12]: com.in_interactive_session()
Out[12]: False
In [1]: import pandas.core.common as com

In [2]: com.in_interactive_session()
Out[2]: True

It appears that using %run to execute a script changes the __main__ module to look like a non-interactive session:

In [1]: import pandas.core.common as com

In [2]: com.in_interactive_session()
Out[2]: True

In [3]: run ib_stmt.py

In [4]: com.in_interactive_session()
Out[4]: False

We should fix this along with a few other little buglets and cut 0.10.1 later this week

@minrk what is the appropriate way to find out if we're inside an interactive IPython session?

Here's my current solution:

def check_main():
    import __main__ as main
    return (not hasattr(main, '__file__') or
            get_option('mode.sim_interactive'))

try:
    return __IPYTHON__ or check_main()
except:
    return check_main()

I typically use the NameError test, but with get_ipython. __IPYTHON__ was added back in, so there could be a way that would work on both sides of the 0.10-0.11 transition.
