;;; autoarg.el --- make digit keys supply prefix args

;;; Commentary:
;; This provides `autoarg-mode', a global minor mode meant to emulate
;; a facility reported from Twenex Emacs whereby digit keys supplied
;; prefix args rather than self inserting, with a digit sequence
;; terminated by space acting to insert the digits.
;; The bindings of DIGIT and C-DIGIT are swapped and a command bound
;; to SPC deals with a numeric prefix arg or acts normally without
;; such an arg. (In the absence of a suitable terminal, you'd
;; probably want to swap DIGIT and M-DIGIT.) See the mode doc.
;; You probably don't really want to use this.
;;; Code:
(defcustom autoarg-mode nil
"Toggle Autoarg mode.
You must modify via \\[customize] for this variable to have an effect."
:set (lambda (symbol vaautoarg-mode (or value 0)))
:initialize 'custom-initialize-default
:type 'boolean
:group 'editing
:require 'autoarg)
;; If you wanted a local mode:
;; (make-variable-buffer-local 'autoarg-mode)
(defvar autoarg-mode-map (make-sparse-keymap)
"Keymap for Autoarg Mode.")
;; Loop over digit characters to set up keymap.

(defun autoarg-mode (&optional arg)
"Toggle Autoarg mode minor mode globally.
With ARG, turn Autoarg mode on if ARG is positive, off otherwise.
In Autoarg mode digits are bound to `digit-argument' -- i.e. they
supply prefix arguments as C-DIGIT and M-DIGIT normally do -- and
C-DIGIT inserts DIGIT. \\[autoarg-terminate] terminates the prefix sequence
and inserts the digits of the autoarg sequence into the buffer.
Without a numeric prefix arg the normal binding of \\[autoarg-terminate] is
invoked, i.e. what it would be with Autoarg mode off.
For example:
`6 9 \\[autoarg-terminate]' inserts `69' into the buffer, as does `C-6 C-9'.
`6 9 a' inserts 69 `a's into the buffer.
`6 9 \\[autoarg-terminate] \\[autoarg-terminate]' inserts `69' into the buffer and
then invokes the normal binding of \\[autoarg-terminate].
`C-u \\[autoarg-terminate]' invokes the normal binding of \\[autoarg-terminate] four times.
