Installation

Require this script

(require 'electric-spacing)

and you may enable electric-spacing-mode with M-x electric-spacing-mode. Loading the mode in major-mode-hooks may also be useful.

(add-hook 'org-mode-hook 'electric-spacing-mode)

Defining Patterns

You may define a pattern where whitespaces should be inserted, by adding a regexp-pair to electric-spacing-regexp-pairs. For example, following setting inserts spaces between Japanese and English characters like: foo ほげ bar ふが

(add-to-list 'electric-spacing-regexp-pairs
             '("\\cA\\|\\cC\\|\\ck\\|\\cK\\|\\cH" . "[0-9A-Za-z]"))
(add-to-list 'electric-spacing-regexp-pairs
             '("[0-9A-Za-z]" . "\\cA\\|\\cC\\|\\ck\\|\\cK\\|\\cH"))

You may define a buffer-local pattern by making electric-spacing-regexp-pairs buffer-local before registering the pattern.
