Suppose I'm at the Sage command line and I type
sage: V = QQ^4
sage: V.basis <ctrl-c>
I am immediately returned to the Sage prompt, with a "KeyboardInterrupt"
message. Great, just what I want. Now suppose I do
sage: V = QQ^4
sage: V.basis(0
and then I hit return. (I meant to type ")" but my finger slipped off of
the shift, so I got "0" instead.) Now I get
....:
I think I used to be able to hit ctrl-c and cancel this, getting back to
the Sage prompt. Now if I hit ctrl-c, I get
KeyboardInterrupt
....:
I can complete the command (by typing ")" then RET), and it will execute
and give me an error because "basis" doesn't take any arguments. Or I can
type "]" then RET and get a SyntaxError. Is there any way to get back to
the Sage prompt without executing the command?
Should we be configuring IPython or readline or something differently to
allow this?
