I think ip.core.ipapi.get() is behaving differently in the trunk than
it did before the refactor. Here is the new implementation:
def get():
"""Get the most recently created InteractiveShell instance."""
from IPython.core.iplib import InteractiveShell
insts = InteractiveShell.get_instances()
most_recent = insts[0]
for inst in insts[1:]:
if inst.created > most_recent.created:
most_recent = inst
return most_recent
If I call get from the python prompt, instead of Ipython, I used to
get None, but now I get an error because insts is an empty list so
insts[0] raises an IndexError. Perhaps:
def get():
"""Get the most recently created InteractiveShell instance."""
from IPython.core.iplib import InteractiveShell
insts = InteractiveShell.get_instances()
if not insts:
return None
most_recent = insts[0]
for inst in insts[1:]:
if inst.created > most_recent.created:
most_recent = inst
return most_recent
