X Implementation Where X = Doom Emacs's +lookup/ Command.

I was trying to figure out +lookup/definition that open in other window. In one of the issue, Henrik ¹ mention that some lookup backend (As an example, xref is a built in backend for lookup) are asynchronous and there is no standardized mechanism to talk to them to see whether the command runs successfully ².

lets call this new command +lookup/definition-other-window Current possible solutions are

1. ignore validation step to make sure that the command runs succesfully.
2. when the command is called, switch to other window then run +lookup/definition command. It can be implemented as followed

      (dolist (fn '(definition references))
        (fset (intern (format "+lookup/%s-other-window" fn))
              (lambda (identifier &optional arg)
                "TODO"
                (interactive (list (doom-thing-at-point-or-region)
                                   current-prefix-arg))
                (let ((pt (point)))
                  (switch-to-buffer-other-window (current-buffer))
                  (goto-char pt)
                  (funcall (intern (format "+lookup/%s" fn)) identifier arg)))))
   

I just thinks its interesting, so I figure I write something about it.

That’s it. Peace.
