Here's some work to make the Erlang shell history
more like readline:
git fetch git://github.com/jdavisp3/otp.git shell
Specifically:
1. Blank lines are not added to the line buffer.
2. Pressing the down arrow on the last line causes no change.
The previous behavior erased the line.
3. The new line is temporarily added to the line buffer
so the user can move to previous lines with up arrows
and then back to the new line with down arrows.
The previous behavior discarded the partially written
new line.
4. Changes made to previous lines while exploring the line
buffer history are preserved.
The previous behavior discarded changes made to older lines.
Any interest in this?
thanks,
dave

The killer feature here is if you can make it record the shell history
between invocations (maybe in ~/.erl_history).
Thanks!

For anyone who hasn't found it, there's a great little utility (on
Linux, at least) called 'rlwrap' which gives you the full readline
feature set on any command line system (like, say, the erlang shell). I
simply have 'erl' aliased to 'rlwrap -a erl'. It gives you everything
provided by this patch as well as as a searchable history (just like you
get in bash with Ctrl-r).
(This isn't meant to suggest that the patch isn't worthwhile, just to
note an alternative).
Cheers,
Bernard

That's what I plan on working on next, assuming there's general
interest in this work, which there seems to be.

That's a cool utility, thanks.

Yep, I think it might still be useful for systems you can't install
extra stuff to.
