インデントに応じて色を変えると便利かと思ったのだが、
こういうことをするためには
文字ごとに属性を設定しなければならないらしい。
面倒なのでやる気がうせたが一応作ってみた。
(setq indent-colors '( "DarkSeaGreen1" "DarkSeaGreen2" "DarkSeaGreen3" "DarkSeaGreen4" "SeaGreen1" "SeaGreen2" "SeaGreen3" "SeaGreen4" "PaleGreen1" "PaleGreen2" "PaleGreen3" )) (defun set-indent-color () (let (symbol face indent) (setq indent (% (indent-level) (length indent-colors))) (setq symbol (make-symbol (concat "indent" (format "%d" indent)))) (setq face (make-face symbol)) (set-face-foreground face "black") (set-face-background face (indent-color indent)) (save-excursion (let (start end) (beginning-of-line) (setq start (point)) (end-of-line) (setq end (point)) (if (looking-at "\n") (setq end (1+ (point)))) (put-text-property start end 'face face) )) )) (defun set-indent-colors () (save-excursion (let (old new (done nil)) (goto-char 1) (setq old (point)) (while (not done) (set-indent-color) (forward-line) (setq new (point)) (setq done (= old new)) (setq old new) ) ))) (defun indent-color (indent) (let (c) (setq c (nth indent indent-colors)) (if (null c) (setq c "white")) c )) (defun indent-level () (save-excursion (progn (beginning-of-line) (re-search-forward "[^ \t]" nil t) (backward-char) (current-column) )))
