[IPython-User] Making Control-D work when the line is not clear
Tue Oct 18 20:49:26 CDT 2011
OK, the solution is kind of obvious. I just need to add '"\\C-d":
"\\C-u\\C-k\\C-d"' to my readline_parse_and_bind. Now, C-d clears the
line and then exits. The only side effect is that it clears the
current "yank" to whatever is before my cursor, but I very rarely use
C-y, so this is no big deal for me. The other side effect is that I
lose whatever I had typed in my terminal's scrollback, but I think I
can also live with this.
It definitely would be nice though if I could just make C-d raise
EOFError (without affecting the input text at all). Would it be
possible to make it so readline commands can execute arbitrary code
internally? I don't know enough about the architecture of IPython to
know if this would be possible or not.
