Rearrange file to group definitions according to their use (types of commands, internal functions, etc.) (todos-file-done, todos-insert-threshold, todos-remove-separator) (todos-date-string, todos-time-string, todos-check-overlay) (todos-show-paren-hack, todos-file-item, todos-more-important-p): Comment out. (todos-current-date, todos-item-end-overlays) (todos-list-categories): Remove. (todos-item-end): Remove (the variable, not the function). (todos-item-overlays): Rename to todos-prefix-overlays and adjust callers. (todos-prefix-overlays): Rename from todos-item-overlays. (todos-done-separator, todos-done-string, todos-show-with-done) (todos-files, todos-archive-file, todos-categories-buffer) (todos-archived-categories-buffer, todos-wrap-lines) (todos-line-wrapping-function): New defcustoms.

(todos-edit-buffer): Change from defvar to defcustom. (todos-font-lock-keywords): Use todos-done-string-match and todos-category-string-match. (todos-backward-item, todos-forward-item): Use todos-done-string and todos-date-pattern. (todos-display-categories): Reimplement using buttons from button.el instead of widgets. (todos-top-priorities): Use with-current-buffer; take done items into account; ensure buffers gets fontified. (todos-add-category): Ensure new category does not begin with empty lines. (todos-jump-to-category): Use todos-category-select instead of todos-show. (todos-rename-category): Prompt for new name in body instead of in interactive spec. (todos-insert-item): Don't insert in done items section of category. Add two optional arguments to control insertion: (i) to insert near point without prompting for priority; (ii) to use defaults for date and time strings, to prompt for these, or to choose date from the Calendar.

(todos-remove-item): Reimplement using todos-forward-item and todos-backward-item; redo overlay handling. (todos-mode-map): Add some new key bindings and change numerous existing bindings; use "i" as prefix key for item insertion commands. (todos-mode): Use todos-wrap-lines and delegate word-wrap and wrap-prefix settings to todos-wrap-and-indent; add to invisibility spec; set buffer-read-only to t and consequently let-bind this variable in all Todos commands that change buffer content. (todos-edit-mode): Make an indepent mode, not derived from text-mode. (todos-save): Don't save top priorities buffer. (todos-show): Make a no-op if called interactively in narrowed Todos mode, since, also to work around item prefix reduplication bug with show-paren-mode enabled; use todos-categories-list. --- diff --git a/lisp/ChangeLog b/lisp/ChangeLog index 4110a4ad087..e2d88a96ac4 100644 --- a/lisp/ChangeLog +++ b/lisp/ChangeLog @@ -1,3 +1,98 @@ +2012-09-13 Stephen Berman + + * calendar/todos.el: Comment out calendar require, since diary-lib + requires calendar.
