;;; Description:
;; Major mode for highlighting a numbered todo list.
;; This is a simple mode that uses a number of regexp's to
;; determine the color of a particular line based on the assigned
;; priority number.
;; The format for a given line is:
;; number (0-4), [optional lower case letter], tab, task text
;; It will also recognize hash style comments to the end of the line.
;; Example:
;; 0 This is a header line that will always be on top.
;; 1 Run around the block.
;; 1 Wash behind my ears.
;; 2a Learn some more Lisp.
;; 2b Fly a kite.
;; 3 Say I'm sorry.
;; 4 Peace to all mankind.
;; Faces are defined in this file below. Feel free to add more or
;; change the colors to suit your own style.
;; Sort on the assigned priority number:
;; Select a region (C-x h for entire buffer), M-x sort-lines
;;; Code:
(setq todo-list-highlight-regexps '(
;;regexp keyword matches:
;;beg line|number|letter?|tab|any char|any chars|end line
