Popup terminal with tmux

.tmux.conf

# ... your other config

bind-key -n M-3 run-shell 'toggle-tmux-popup'
# you can switch `M-3` to any keybindings you like.

toggle-tmux-popup

#!/bin/bash
# 👻 put this file into your $PATH, normally `~/.local/bin/toggle-tmux-popup`
# 👻 this script should have runable permission.

if [ "$(tmux display-message -p -F "#{session_name}")" = "popup" ];then
    tmux detach-client
else
    tmux popup -d '#{pane_current_path}' -xC -yC -w80% -h75% -E "tmux attach -t popup || tmux new -s popup"
fi

Pop-up windows based on the current directory name.

bind-key -n M-g if-shell -F '#{==:#{session_name},#{b:pane_current_path}}' {
    detach-client
} {
    display-popup -d "#{pane_current_path}" -xC -yC -w 90% -h 85% -E 'tmux new-session -A -s (tmux display-message -p "#{b:pane_current_path}")'
}

I found that popup tmux session cannot share clipboard in copy-mode-vi.
Does someone know what the problem and how to solve it?

bind-key -T copy-mode-vi y                 send-keys -X copy-pipe 'tmux save-buffer - | wl-copy'

@gogongxt It works fine on my machine. I have the following in my .tmux.conf:

# Be more like Vim in copy-mode-vi
bind-key -T copy-mode-vi y send-keys -X copy-pipe 'xclip -i -selection clipboard'
bind-key -T copy-mode-vi Y send-keys -X copy-pipe-end-of-line 'xclip -i -selection clipboard'
bind-key -T copy-mode-vi v if-shell -F '#{selection_active}' { send-keys -X clear-selection } { send-keys -X begin-selection }

Just want to share my config, this will open and cd to the current directory of the active pane, silently:

# popuptmux

#!/bin/sh
set -e
width=${1:-63%}
height=${2:-75%}
SESSION_NAME="popup"
CURRENT_PANE="$(tmux display-message -p -F "#{session_name}")"
if echo "$CURRENT_PANE" | grep -q '^popup.*'; then
    tmux detach-client
else
    current_path=$(tmux display-message -p -F "#{pane_current_path}")
    if tmux has-session -t "$SESSION_NAME" 2>/dev/null; then
        tmux setenv -t "$SESSION_NAME" POPUP_PATH "$current_path"
        PANE_CMD=$(tmux display-message -t "$SESSION_NAME" -p -F "#{pane_current_command}")
        case "$PANE_CMD" in
            *sh)
                PANE_PID=$(tmux display-message -t "$SESSION_NAME" -p -F "#{pane_pid}")
                kill -USR1 "$PANE_PID" 2>/dev/null || true
                ;;
            *)
                # If running something else (vim), do nothing
                ;;
        esac
        
        tmux popup -d "$current_path" -xC -yC -w$width -h$height -E "tmux attach -t $SESSION_NAME"
    else
        tmux popup -d "$current_path" -xC -yC -w$width -h$height -E "tmux new -s $SESSION_NAME -c \"$current_path\""
