Opening an IPython shell on any (uncaught) exception

Question

I have defined the following (embedded) shell in Python:

from IPython.config.loader import Config
cfg = Config()
prompt_config = cfg.PromptManager
prompt_con

Defining the following in my ipython shell seems to do what you want:

def custom_exc(shell, etype, evalue, tb, tb_offset=None):
    shell.showtraceback((etype, evalue, tb), tb_offset=tb_offset)
    ipshell()

get_ipython().set_custom_exc((Exception,), custom_exc)
