numeric keys in vim are wrong in urxvt

[jo...@technoplaza.net]

I’m having problems with certain keys on my numpad in vim when using tmux. They work outside of vim. It’s all the keys other than the numbers. The numbers work. (/ * - + . ENTER do not).

 

I am using rxvt-unicode-256color. When stating the terminal emulator, I have my TERM set to rxvt-unicode-256color. In tmux, the TERM is set to screen-256color.

 

The tmux version is 2.7 on the jump host I am using, but I installed a local copy of tmux 2.9a, and it made no difference.

 

If I set the TERM (in tmux) to rxvt-256color, the numpad keys work, but HOME and END stop working. I can fix that by setting the TERM to linux and then immediately back to rxvt-256color.

 

So the only way I have found to get all the keys working is to do this in my bashrc.

 

export TERM=linux

export TERM=rxvt-256color

 

Am I doing something wrong?

 

Thanks.

If you run "cat" inside tmux and press the problem keys, what do you see?

What if you do "tput smkx" then "cat"?

This is pressing, on the numeric keypad, on an Apple keyboard, =, /, *, -, +, and ENTER.

$ cat
^K/*-+

/*-+
^C
$ tput smkx
$ cat
^K^[Oo^[Oj^[Om^[Ok^[OM

ojmkM

I get the same results inside vim before and after the tput command.

This seems correct, this sounds like a problem with vim to me, the
numeric key escape sequences are not listed in terminfo so my guess
would be it is sending smkx and has hardcoded the escape sequences it
expects for TERM rxvt* but not for screen* and tmux*.

Don't you have a numlock? rxvt should send the symbols directly even
with smkx when it is on.

There is no key labeled "numlock" on my apple keyboard, the "clear" key in
the same place seems to function the same way.

I'm not really following about the escape sequences. Are you saying terminfo
with rxvt-256color, vim has a hardcoded understanding of the keys, but with
screen-256color, it does not? i.e. vim knows rxvt doesn't define these keys,
but someone patched vim to understand it rather than fixing the terminfo
file?

I was able to put this in vim to remap the keys, but it feels more like a
hack than a fix.

" fix keypad keys in tmux/urxvt
:inoremap <C-K> =

:inoremap <Esc>Oo /

:inoremap <Esc>Oj *

:inoremap <Esc>Om -

:inoremap <Esc>Ok +

:inoremap <Esc>OM <Enter>

:inoremap <Esc>On .

Hi

I was wrong actually, rxvt-256color does list the keypad keys, but tmux
and screen do not so that's probably why it works and they don't. So
unless you want to build your own modified terminfo entry then mapping
them yourself in your vim config is the best solution.

Thanks. That's what I'll do for now then.
