How to start slime automatically and layout as I want

Question

I'm now using this config:

(use-package slime
  ...
  ...
  :hook
  (slime-mode . (lambda ()
          (unless (slime-connected-p)
            (let ((bak-buffer (current-buffer)))
              ;; (delete-other-windows)
              ;; (split-window-horizontally)
              (save-excursion (slime))
              ))
          )))

And that is what I get when open a .lisp first time(previous window is only a scratch window)

But what I want is something like this:

Notice that I want slime to be on the left, and .lisp to be right, due to some environmental factor.

This code seems to work

(slime-mode . (lambda ()
          (unless (slime-connected-p)
            (let ((bak-buffer (current-buffer)))
              (slime)
              (delete-other-windows)
              (split-window-horizontally)
              (other-window 1)
              (switch-to-buffer bak-buffer)
              ))
          ))

• Looks like slime-mode is applied to the buffer when you open a lisp file, and it is evaluating (slime) that opens a REPL and layout the windows as 3.

• (slime) and your code both do window layouting and obviously the one executed later would overwrite what's done earlier.

So you need to put extra window layouting after the statement (slime).
