;;; Commentary:
|
|
|
|
;; Sequence-manipulation functions that complement basic functions
|
|
;; provided by subr.el.
|
|
;;
|
|
;; All functions are prefixed with "seq-".
|
|
;;
|
|
;; All provided functions work on lists, strings and vectors.
|
|
;;
|
|
;; Functions taking a predicate or iterating over a sequence using a
|
|
;; function as argument take the function as their first argument and
|
|
;; the sequence as their second argument. All other functions take
|
|
;; the sequence as their first argument.
|
|
;;
|
|
;; seq.el can be extended to support new type of sequences. Here are
|
|
;; the generic functions that must be implemented by new seq types:
|
|
;; - `seq-elt'
|
|
;; - `seq-length'
|
|
;; - `seq-do'
|
|
;; - `seqp'
|
|
;; - `seq-subseq'
|
|
;; - `seq-into-sequence'
|
|
;; - `seq-copy'
|
|
;; - `seq-into'
|
|
|
|
;;; Code:
|
|
|
|
(if (version< emacs-version "25")
|
|
(require 'seq-24)
|
|
(require 'seq-25))
|
|
|
|
(provide 'seq)

;;; seq.el ends here
