Subject: 26.1; emacsclient forgetting keybinds set by tty-setup-hook
Date: Mon, 26 Nov 2018 11:51:51 +0100

Hello, by using these two files:
$ cat ~/.emacs
(add-to-list 'load-path "~/.emacs.d/lisp/")
$ cat -A ~/.emacs.d/lisp/term/st.el | sed 's#\$$##'
(message "Registering st keybinds")
(define-key input-decode-map "^[[1;5A" [C-up])
(define-key input-decode-map "^[[1;5B" [C-down])
(define-key input-decode-map "^[[1;5C" [C-right])
(define-key input-decode-map "^[[1;5D" [C-left])
(define-key input-decode-map "^[[1~" [home])
(define-key input-decode-map "^[[4~" [end])

I get the keybinds I want when using emacs -nw with st, but when using
emacs --daemon and emacsclient, these work only the first time:
$ emacs --daemon
$ emacsclient -nw myfile # no problem, close with C-x C-c
$ emacsclient -nw myfile # from here, tty frames don't remember the bindings

What key stroke is "^[[1;5A" (etc) representing?

Hello

as the line says, "Ctrl + Up arrow". I think I stopped used emacsclient because
of this, actually.

Regards

When I use emacsclient -nw (Debian bullseye), `C-up' works without
altering input-decode-map, so I'm wondering why your terminal is sending
key sequences making it necessary to alter input-decode-map.

Most probably because Emacs has some defaults for xterm based terminals, which
st isn't. And Emacs needs those defaults because "C-up" isn't described by
terminfo.

Anyway, that's not really the problem, the bindings shouldn't
disappear. Mind you, I haven't try to reproduce it with the current version,
I'll probably get to it.

So maybe the way forward is to update lisp/term/st.el with these
sequences?  Currently, we behave as if st is the same as xterm.

Please do, perhaps the latest code already fixes this problem.

Thanks.

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

Hadrien, are you still seeing these issues in more recent Emacs
versions?

Hello and sorry for my lack of effort, I reproduced it with Emacs 28.0.91 (built today).
