Elisp: List Iteration

By Xah Lee. Date: . Last updated: .

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〕 

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

;; inserts 12345
;; return nil
