Elisp: List Iteration

dolist

dolist

• (dolist (VAR LIST) BODY)
• (dolist (VAR LIST RESULT) BODY)

• Loop over a List.
• Each time eval BODY, with VAR having value of an element in list.
• Return nil or RESULT.
• RESULT is evaluated last.

💡 TIP: for sequence, use seq-doseq. 〔see Elisp: Sequence. Iteration Guide〕

(let (xx)
  (setq xx (number-sequence 1 5))
  (dolist (n xx)
    (insert (number-to-string n))))

;; inserts 12345
;; return nil
