Quickstart

(require 'vector-utils)
 
(vector-utils-flatten '[1 2 [3 4 [5 6 7]]])
;; '[1 2 3 4 5 6 7]
 
(vector-utils-depth '[1 2 [3 4 [5 6 7]]])
;; 3

vector-utils

Vector-utils is a collection of functions for vector manipulation. This library has no user-level interface; it is only useful for programming in Emacs Lisp.

Furthermore (when programming in Emacs Lisp), be aware that the modification of a vector is not permitted: only vector elements may be changed. All "modification" operations herein can only work by making copies, which is not efficient.

The following functions are provided:

vector-utils-depth
vector-utils-flatten
vector-utils-insert-before
vector-utils-insert-after
vector-utils-insert-before-pos
vector-utils-insert-after-pos

To use vector-utils, place the vector-utils.el library somewhere Emacs can find it, and add the following to your ~/.emacs file:

(require 'vector-utils)
