I'm forwarding here a user question.
Andrew, please note that non-subscriber postings are disabled to the ipython
lists, due to the ridiculous amount of spam we were getting. I got your
message forwarded to me by the mailman auto-discarder. Sorry for this, but
the spam problem was getting out of hand.

1. Can I recall an history event by line number in IPython like you can in
the shell with !<line #> ? If there's a choice, I'd prefer a recall that
works like zsh's HIST_VERIFY option which lets you edit the line before
2. I'm not getting file or directory completion. I know this should work
but pressing the TAB key doesn't return any completions. Changing
the command from 'ls' to '@ls' to '!ls' doesn't make any difference.
I'm using IPython 5.0 over zsh on Debian unstable.
1. All the history is held in by line number in the In array, so you can type:
In : print 'hi'
In : exec In
But there's no editing other than by normal python means:
In : exec In.replace('hi','hello')
If anyone knows of a reasonably simple way of implementing Andrew's request,
I'm all ears.
2. You are probably using python 2.3. Python changed its readline behavior at
the C level in 2.3 and they broke filename and directory completion. Thanks
to Jeff Collins, ipython's current cvs code already implements a workaround,
but this hasn't been released yet (it's available to you if you want to use
the CVS code). We'll have an official new release out in the next few weeks.
