[Caml-list] Configure utop to use rlwrap/emacs history keys?

[Caml-list] Configure utop to use rlwrap/emacs history keys?

[Marshall]

Newbie question:

On OSX 10.11, I would like to configure utop so that Ctrl-P moves to the previously entered line of code, and so that Ctrl-N moves back down toward the most recent line.  According to what ‘man lambda-term-inputrc' and ‘lambda-term-actions’ say, it seems to me that I ought to be able to get this behavior by putting the following in .lambda-term-inputrc in my home directory:

[read-line]
C-p: next-line 
C-n: prev-line

However, this configuration to have no effect.  I can move up and down through command history using the arrow keys, as I could without the rc file, Ctrl-P and Ctrl-N still do nothing.

Thanks very much-

Marshall

M-n (Meta = Alt) and M-p are the keyboard shortcuts your are looking for

I.e. replace Ctrl by Alt and do not configure anything to get that 
Emacs-like behavior.

I agree with your reading of lambda-term-inputrc man page, but I disagree
with your reading of the output of lambda-term-actions.  I think the
following stanza should give you the effect you want:

[read-line]
C-p: history-next
C-n: history-prev

Thanks for all of the replies.

Zhenya, history-next/prev was the key.  Excellent!  Now I can work happily.  Thanks very much.

I noticed that caml-list emails have reply-to set to the person who posted.  Is it the convention to reply off-list for most followups of this kind?

(Francois, I checked and ^P and ^N actually are the Emacs previous/next line keys in my vanilla Emacs—it wasn’t just my fingers that thought so!  Meta-P and Meta-N are unbound.  (I have to use the uber-traditional Esc- prefix to get Meta, as Alt- and Apple- do other things by default for me.))

(Tao: Yeah, lately Apple sometimes seems to have a “if it’s not broken and is better than anything else, let’s mess it up” attitude.  I think the X is supposed to be Roman numeral 10, so maybe Apple is planning to increment X and doesn’t like "OSXI".)
