Another, maybe simpler idea: have a command axiom-set-face which allows the
user to specify a face and make within the output region the up, down, right
and left paint. Or maybe M-up, M-down, M-right and M-left. Or the same with
C-prefix. This would render the implementation trivial, probably, and may even
be more useable.
We need cursor combinations for:
* move to previous input line
* get previous input C-up / C-down
* move within the input region left / right
* move within the output region
* paint within the output region
Thus, maybe:
left/right/up/down: move ordinarily (i.e., one line)
Shift-left/right/up/down: paint within output region
Ctrl-up/down fetch previous/next input
M-up/down move to previous / next input.
What do you think?
-------------------------------------------------------------------------------
Apart from this, I seem to have a problem with overlays:
(defface axiom-blue-output '((t (:background "blue")))
""
:group 'axiom)
(defface axiom-red-output '((t (:background "red")))
""
:group 'axiom)
(defun make-blue ()
(interactive)
(let ((over (make-overlay (point) (+ (point) 1) nil nil t)))
(overlay-put over 'face 'axiom-blue-output)))
(defun make-red ()
(interactive)
(let ((over (make-overlay (point) (+ (point) 1) nil nil t)))
(overlay-put over 'face 'axiom-red-output)))
It seems that I cannot color something blue that was previously red?
