Sure, but me personally, I prefer using `cond' but would not mix it with `if' in the same time:
Instead of:
(defun txcomplt-light (featr)
"DOCSTRING."
(cond
((eq 'company featr)
(if (equal 2 (aref recorder 0))
(message "Light | Green")
(message "Light | Amber")))
((eq 'corfu featr)
(if (equal 2 (aref recorder 1))
(message "Light | Green")
(message "Light | Amber")))) )
(defun txcomplt-light (featr)
"DOCSTRING."
(cond ((and (eq 'company featr) (equal 2 (aref recorder 0))) (message "Light | Green"))
((and (eq 'corfu featr) (equal 2 (aref recorder 1))) (message "Light | Amber"))))
However, I did not maybe make your logic right. I hope you see that `if' is not necessary.
To make function return anything, just make the value that you wish returned the last one:
(defun txcomplt-light (featr)
"DOCSTRING."
(cond ((and (eq 'company featr) (equal 2 (aref recorder 0)))
(message "Light | Green")
"Green") ;; this is what is returned
((and (eq 'corfu featr) (equal 2 (aref recorder 1)))
(message "Light | Amber")
"Amber"))) ;; this is what is returned
