zellij-sessionizer: ThePrimeagen/tmux-sessionizer but for zellij

zellij-sessionizer

#!/usr/bin/env bash

# set your own root folders, all children folders will become options for in sessionizer menu
root_folders="$HOME/projects $HOME/work $HOME/.config"

function attach_session() {
    local session_root=$1
    local session_name=$(basename "$session_root" | tr . _)
    cd $session_root
    zellij attach --create $session_name
}

quit_option="=== Quit sessionizer ==="
last_session=""
while true; do
    selected_option=$( (echo $quit_option && find $root_folders -mindepth 1 -maxdepth 1 -type d) | fzf)

    if [[ $selected_option == $quit_option ]]; then
        exit 0
    fi
    
    if [[ -z $selected_option && -z $last_session ]]; then
        exit 0
    fi

    if [[ -z $selected_option ]]; then
        attach_session $last_session
    else
        last_session=$selected_option
        attach_session $selected_option
    fi
done

In the end I abandoned using Zellij, why:

1. must have for me, that's impossible to emulate in Zellij:
   • tmux provides nice way for fast switching between current and previous session
   • fzf is running inside tmux, so if I change my mind, I can just press Esc to return to current session
2. nice things:
   • tmux covers all my needs or Zellij doesn't provide anything new, that's useful for me
   • I don't like Zellij view: all this green frames or lines, and I don't see easy way to customize it
   • I don't like keybinding: there're a lot of them and they conflict with what I set in Vim, so I need to always keep Zellij in locked mode and modify keybinding for all mode transitions: a lot of work, complex custom config. I don't see a need in all these mode transitions in the first place
