tui: Numpad doesn't work anymore

[to-huu]

Hello,
i upgraded from nvim v.2.0 and now the numpad isn't working anymore.
I've tried to remap, but without success.

• nvim --version: NVIM v.0.2.3-24-gd9b3ebfed
• Operating system/version: Arch Linux49 (4.9.63-1)
• Terminal name/version:urxvt v9.22
• $TERM:rxvt-unicode-256color

Kind regards

Hello,
This is a surprising issue. Does the numpad work in your shell? If yes, what happens when you press C-v+ a numpad number in insert mode in neovim? Does the same thing happen in your shell?

Hello,
i'm having the same problem. C-v and a numpad character does nothing in nvim, but prints most of the numpad characters in the shell. oddly, only 123456 and not 789. but without C-v it works in the shell.

except for the OS (Debian with 4.9.30-2 kernel), i'm having the same specs.
cheers

Hello,
in the shell the numpad works fine (with and without C-v). In neovim nothing happens with C-v either.
Kind regards

I'm working on restoring :set termcap so we can diagnose TUI issues a bit better. Will revisit this then.

@sputny if you are able to build from source, could you try #7653 and post the log file from:

./build/bin/nvim -V3log

[justinmk]

  key_a1                    ka1        = <Esc>Ow
  key_a3                    ka3        = <Esc>Oy
  key_b2                    kb2        = <Esc>Ou
  key_c1                    kc1        = <Esc>Oq
  key_c3                    kc3        = <Esc>Os

This means Nvim (and your terminfo) thinks that <Esc>Ow is "keypad 1". That usually means "7" or "Home" on the numpad. Please try this, using the numpad in all cases:

• In your shell (bash), type CTRL-v then <Home>. What does it print?
• In your shell (bash), type CTRL-v then 7. What does it print?
• In Nvim, in insert-mode, type CTRL-v then <Home>. What does it print?
• In Nvim, in insert-mode, type CTRL-v then 7. What does it print?

Also if anyone can try reverting 5701165 to see if that helps, that would be useful.

Hey all,
that happens:

• bash, CTRL-v then <Home> prints ^[[7~
• bash, CTRL-v then <7> prints7
• Nvim, CTRL-v then <Home> prints <home>
• Nvim, CTRL-v then <7> prints ^
