Is there a command like switch-session [-np] that switches based on the order appearing in choose-session?

[allisnulll]

bind -n M-J switch-client -n
bind -n M-K switch-client -p

I used these bindings assuming that they followed the same order order from choose-session and kept getting confused at where they would take me. I looked at the man page and found out about how they actually work but I cant find anything on choose-session or how to get the numbers it uses. I just want to go up and down this menu without actually opening it. Is there some way to output the sessions sorted by age?

There is nothing builtin... I'd like it if switch-client had a -O flag to specify the sort order in the same way as choose-session (maybe list-sessions etc as well).

You could make choose-session sort by name to match switch-client by doing choose-session -Oname (or pressing O after entering tree mode).

If you want switch-client in ID order instead of name you will need to do it yourself, so something like this for next:

S=$(tmux display -p '#{session_id}')
N=$(tmux ls -F '#{session_id}'|sort -nk2 -t'$'|sed -n "/^$S$/{n;p}")
if [ x$N = x ]; then
        N=$(tmux ls -F '#{session_id}'|sort -nk2 -t'$'|head -1)
fi
tmux switchc -t$N

And for previous:

S=$(tmux display -p '#{session_id}')
N=$(tmux ls -F '#{session_id}'|sort -nk2 -t'$'|sed -n "1!{/^$S$/{x;p}}; h")
if [ x$N = x ]; then
        N=$(tmux ls -F '#{session_id}'|sort -nk2 -t'$'|tail -1)
fi
tmux switchc -t$N

There may be a tidier way to do this using the #{S/i:#{session_id}} format...

I see, so the ids are in the order I want. Thanks for the script, this is what I ended up using:

bind -n M-S-Down run-shell "~/.dotfiles/scripts/switch-session.sh n"
bind -n M-S-Up run-shell "~/.dotfiles/scripts/switch-session.sh p"

#!/usr/bin/env bash

SESSIONS=$(tmux ls -F "#{session_id}" | sort -nk2 -t"$")
CURRENT_SESSION=$(tmux display -p "#{session_id}")
if [[ $1 == p ]]; then
    TARGET=$(echo "$SESSIONS" | sed -n "/^$CURRENT_SESSION$/{x;p}; h")
    [[ -z $TARGET ]] && TARGET=$(echo "$SESSIONS" | tail -1)
else
    TARGET=$(echo "$SESSIONS" | sed -n "/^$CURRENT_SESSION$/{n;p}")
    [[ -z $TARGET ]] && TARGET=$(echo "$SESSIONS" | head -1)
fi

tmux switchc -t "$TARGET"

Yeah choose-session defaults to ID order which is effectively order of creation because IDs always increase.
