Not working with ipython

[pablogsal]

The following piece of code

import tracestack
tracestack.on()
1 / 0

does work on the standard python interpreter (2.7.10) but no in ipython (4.0.0). The exit in ipython is obviously:

In [1]: import tracestack

In [2]: tracestack.on()

In [3]: 1 / 0
---------------------------------------------------------------------------
ZeroDivisionError                         Traceback (most recent call last)
<ipython-input-3-b710d87c980c> in <module>()
----> 1 1 / 0

ZeroDivisionError: integer division or modulo by zero

and nothing happens.

Some ideas?

Thanks. It looks like IPython doesn't use sys.excepthook.

I think we'll have to test for IPython and, if the user is using it, override the showsyntaxerror and showtraceback methods of IPython.core.interactiveshell.InteractiveShell to have them invoke the custom handler.

Conveniently, this is precisely what we do for python's interactive interpreter in console.py; inconveniently code.InteractiveInterpreter is an old-style class in Python 2.7 so multiple inheritance may not be possible. I'll take a look and try to patch tonight or tomorrow.
