JOVE - How do you keymap VT100 arrow keys?

[Alan Coopersmith]

I would like to use my VT100 arrow keys in jove instead of the built-ins
(^N, ^P, ^F, ^B). To do this, I tried putting the following in my .joverc
file:

make-keymap vt102-map
bind-keymap-to-key vt102-map ^[[
bind-to-key next-line ^[[B
bind-to-key previous-line ^[[A
bind-to-key forward-character ^[[C
bind-to-key backward-character ^[[D

I got this listing from Section 16.25 of the "JOVE Manual for UNIX Users"
(by Jonathon Payne, revised for 4.3BSD by Doug Kingston & Mark Seiden).

Here's the catch - This doesn't work on the version of JOVE installed here
on the OCF Machines (Version 4.9). Sourcing the file gives an error of:
["bind-keymap-to-key" unknown]

Trying to manually bind the keys (by typing M-X bind-to-key next-line ^[[B)
results in a binding to M-[, so that pushing any arrow key move down a line
and inserts A, B, C, or D (depeding on which arrow).

Is there any way to fix this? How?

Please email al...@ocf.berkeley.edu and I will post a summary if there is
interest.

Yes, version 4.14 of Jove can do this. Available for ftp at simtel and
wuarchive. I believe that the version in msdos/editor(s) (?) has some
bugfixes by someone that wasn't envolved in the original development.

I received requests for a summary of what I found out so here goes:

There are 3 basic solutions (all of which are commands put in your
.joverc file):

1. Upgrade to version 4.14 (I was told 4.9 really means 4.09) and use:

> make-keymap vt100-map
> bind-keymap-to-key vt100-map ^[[

> bind-to-key next-line ^[[B
> bind-to-key previous-line ^[[A
> bind-to-key forward-character ^[[C
> bind-to-key backward-character ^[[D

2. Use this (not sure which version):

bind-to-key prefix-3 ^[[

bind-to-key next-line ^[[B
bind-to-key previous-line ^[[A
bind-to-key forward-character ^[[C
bind-to-key backward-character ^[[D

3. Stay with version 4.9 and use:

bind-to-key ansi-codes ^[[
bind-to-key ansi-codes ^[O

I will use #3 since it doesn't require bothering the overworked/unpaid
OCF staff to install a new version. It is also the simplest, but only
works with vt100/ANSI term types. If you want to do assign keys on a
vt220 or a Sun or anything else that doesn't use the vt100 key codes, you
need a version past 4.9. (To find out what version you have type M-X
version).

Thank you for solution 3, adding it to my ~/.joverc works fine for me.
I'm playing with 2.11 BSD on an emulated PDP-11 under SIMH, it has jove 4.9.
