Dunno. It works for me (i.e. I get the expected "error: option --foo:
invalid integer value: 'a'"). Have you tried it outside of IPython?
yes:
python test_opt.py
Traceback (most recent call last):
File "test_opt.py", line 12, in <module>
(opt,args) = parser.parse_args ('--foo')
Ah, that's different. parse_args() takes a list, not a string.
