My local configuration in .zshrc

I have configured my zsh to open a project in a tmux session, with neovim as the editor and zsh as the shell below the editor window.

nvop () {
    WORK_DIR=$1
    if [[ "$WORK_DIR" == "" ]]
    then
        echo "No work directory"
    fi
    echo "Work directory: $WORK_DIR"

    if [[ "$SESSION" == "" ]]
    then
        SESSION="work";
    fi
    echo "Session name: $SESSION"

    tmux kill-session -t $SESSION 
    tmux new-session -s $SESSION -d 
    tmux send-keys -t $SESSION:0.0 "cd $WORK_DIR && nv ." ENTER
    tmux split-window -v
    tmux resize-pane -t $SESSION:0.1 -D 10
    tmux send-keys -t $SESSION:0.1 "cd $WORK_DIR && clear" ENTER
    tmux -2 attach-session -d -t $SESSION:0.0 
}
