There are facilities to add new items, which are -;; categorized, to edit or even delete items from the buffer. -;; The buffer contents are currently compatible with the diary, -;; so that the list of todo-items will show up in the FANCY diary -;; mode. -;; -;; Notice: Besides the major mode, this file also exports the -;; function `todo-show' which will change to the one specific -;; TODO file that has been specified in the todo-file-do -;; variable. If this file does not conform to the TODO mode -;; conventions, the todo-show function will add the appropriate -;; header and footer. I don't anticipate this to cause much -;; grief, but be warned, in case you attempt to read a plain text -;; file. -;; -;; Preface, Quickstart Installation -;; -;; To get this to work, make Emacs execute the line -;; -;; (autoload 'todo-mode "todo-mode" -;; "Major mode for editing TODO lists." t) -;; (autoload 'todo-show "todo-mode" -;; "Show TODO items." t) -;; (autoload 'todo-insert-item "todo-mode" -;; "Add TODO item." t) -;; -;; You may now enter new items by typing "M-x todo-insert-item", -;; or enter your TODO list file by typing "M-x todo-show". -;; -;; The TODO list file has a special format and some auxiliary -;; information, which will be added by the todo-show function if -;; it attempts to visit an un-initialized file. Hence it is -;; recommended to use the todo-show function for the first time, -;; in order to initialize the file, but it is not necessary -;; afterwards. -;; -;; As these commands are quite long to type, I would recommend -;; the addition of two bindings to your to your global keymap. I -;; personally have the following in my initialization file: -;; -;; (global-set-key "\C-ct" 'todo-show) ; switch to TODO buffer -;; (global-set-key "\C-ci" 'todo-insert-item) ; insert new item -;; -;; Note, however, that this recommendation has prompted some -;; criticism, since the keys C-c LETTER are reserved for user -;; functions. I believe my recommendation is acceptable, since -;; the Emacs Lisp Manual *Tips* section also details that the -;; mode itself should not bind any functions to those keys. The -;; express aim of the above two bindings is to work outside the -;; mode, which doesn't need the show function and offers a -;; different binding for the insert function. They serve as -;; shortcuts and are not even needed (since the TODO mode will be -;; entered by visiting the TODO file, and later by switching to -;; its buffer). -;; -;; If you are an advanced user of this package, please consult -;; the whole source code for autoloads, because there are several -;; extensions that are not explicitly listed in the above quick -;; installation. -;; -;; Pre-Requisites -;; -;; This package will require the following packages to be -;; available on the load-path: -;; -;; time-stamp -;; easymenu -;; -;; Operation -;; -;; You will have the following facilities available: -;; -;; M-x todo-show will enter the todo list screen, here type -;; -;; + to go to next category -;; - to go to previous category -;; d to file the current entry, including a -;; comment and timestamp -;; e to edit the current entry -;; E to edit a multi-line entry -;; f to file the current entry, including a -;; comment and timestamp -;; i to insert a new entry, with prefix, omit category -;; I to insert a new entry at current cursor position -;; j jump to category -;; k to kill the current entry -;; l to lower the current entry's priority -;; n for the next entry -;; p for the previous entry -;; P print -;; q to save the list and exit the buffer -;; r to raise the current entry's priority -;; s to save the list -;; S to save the list of top priorities -;; t show top priority items for each category -;; -;; When you add a new entry, you are asked for the text and then -;; for the category. I for example have categories for things -;; that I want to do in the office (like mail my mum), that I -;; want to do in town (like buy cornflakes) and things I want to -;; do at home (move my suitcases). The categories can be -;; selected with the cursor keys and if you type in the name of a -;; category which didn't exist before, an empty category of the -;; desired name will be added and filled with the new entry. -;; -;; Configuration -;; -;; Variable todo-prefix -;; -;; I would like to recommend that you use the prefix "*/*" (by -;; leaving the variable 'todo-prefix' untouched) so that the -;; diary displays each entry every day. -;; -;; To understand what I mean, please read the documentation that -;; goes with the calendar since that will tell you how you can -;; set up the fancy diary display and use the #include command to -;; include your todo list file as part of your diary. -;; -;; If you have the diary package set up to usually display more -;; than one day's entries at once, consider using -;; -;; "&%%(equal (calendar-current-date) date)" -;; -;; as the value of `todo-prefix'. Please note that this may slow -;; down the processing of your diary file some. -;; -;; Carsten Dominik <dominik@strw.LeidenUniv.nl> suggested that -;; -;; "&%%(todo-cp)" -;; -;; might be nicer and to that effect a function has been declared -;; further down in the code. You may wish to auto-load this. -;; -;; Carsten also writes that *changing* the prefix after the -;; todo list is already established is not as simple as changing -;; the variable - the todo files have to be changed by hand. -;; -;; Variable todo-file-do -;; -;; This variable is fairly self-explanatory. You have to store -;; your TODO list somewhere. This variable tells the package -;; where to go and find this file. -;; -;; Variable todo-file-done -;; -;; Even when you're done, you may wish to retain the entries. -;; Given that they're timestamped and you are offered to add a -;; comment, this can make a useful diary of past events. It will -;; even blend in with the EMACS diary package. So anyway, this -;; variable holds the name of the file for the filed todo-items. -;; -;; Variable todo-file-top -;; -;; File storing the top priorities of your TODO list when -;; todo-save-top-priorities is non-nil. Nice to include in your -;; diary instead of the complete TODO list. -;; -;; Variable todo-mode-hook -;; -;; Just like other modes, too, this mode offers to call your -;; functions before it goes about its business. This variable -;; will be inspected for any functions you may wish to have -;; called once the other TODO mode preparations have been -;; completed. -;; -;; Variable todo-insert-threshold -;; -;; Another nifty feature is the insertion accuracy. If you have -;; 8 items in your TODO list, then you may get asked 4 questions -;; by the binary insertion algorithm. However, you may not -;; really have a need for such accurate priorities amongst your -;; TODO items. If you now think about the binary insertion -;; halving the size of the window each time, then the threshold -;; is the window size at which it will stop. If you set the -;; threshold to zero, the upper and lower bound will coincide at -;; the end of the loop and you will insert your item just before -;; that point. If you set the threshold to, e.g. 8, it will stop -;; as soon as the window size drops below that amount and will -;; insert the item in the approximate center of that window. I -;; got the idea for this feature after reading a very helpful -;; e-mail reply from Trey Jackson <trey@cs.berkeley.edu> who -;; corrected some of my awful coding and pointed me towards some -;; good reading. Thanks Trey! -;; -;; Things to do -;; -;; These originally were my ideas, but now also include all the -;; suggestions that I included before forgetting them: -;; -;; o Fancy fonts for todo/top-priority buffer -;; o Remove todo-prefix option in todo-top-priorities -;; o Rename category -;; o Move entry from one category to another one -;; o Entries which both have the generic */* prefix and a -;; "deadline" entry which are understood by diary, indicating -;; an event (unless marked by &) -;; o The optional COUNT variable of todo-forward-item should be -;; applied to the other functions performing similar tasks -;; o Modularization could be done for repeated elements of -;; the code, like the completing-read lines of code. -;; o license / version function -;; o export to diary file -;; o todo-report-bug -;; o GNATS support -;; o elide multiline (as in bbdb, or, to a lesser degree, in -;; outline mode) -;; o rewrite complete package to store data as Lisp objects -;; and have display modes for display, for diary export, -;; etc. (Richard Stallman pointed out this is a bad idea) -;; o so base todo-mode.el on generic-mode.el instead -;; -;; History and Gossip -;; -;; Many thanks to all the ones who have contributed to the -;; evolution of this package!
