;;; Commentary:
|
|
|
|
;; * The idea
|
|
;;
|
|
;; Todo lists, schedules, phone databases... everything we use
|
|
;; databases for is really just a way to extend the power of our
|
|
;; memory. To be able to remember what our conscious mind may not
|
|
;; currently have access to.
|
|
;;
|
|
;; There are many different databases out there -- and good ones --
|
|
;; which this mode is not trying to replace. Rather, it's how that
|
|
;; data gets there that's the question. Most of the time, we just
|
|
;; want to say "Remember so-and-so's phone number, or that I have to
|
|
;; buy dinner for the cats tonight." That's the FACT. How it's
|
|
;; stored is really the computer's problem. But at this point in
|
|
;; time, it's most definitely also the user's problem, and sometimes
|
|
;; so laboriously so that people just let data slip, rather than
|
|
;; expend the effort to record it.
|
|
;;
|
|
;; "Remember" is a mode for remembering data. It uses whatever
|
|
;; back-end is appropriate to record and correlate the data, but it's
|
|
;; main intention is to allow you to express as _little_ structure as
|
|
;; possible up front. If you later want to express more powerful
|
|
;; relationships between your data, or state assumptions that were at
|
|
;; first too implicit to be recognized, you can "study" the data later
|
|
;; and rearrange it. But the initial "just remember this" impulse
|
|
;; should be as close to simply throwing the data at Emacs as
|
|
;; possible.
|
|
;;
|
|
;; * Implementation
|
|
;;
|
|
;; Hyperbole, as a data presentation tool, always struck me as being
|
|
;; very powerful, but it seemed to require a lot of "front-end" work
|
|
;; before that data was really available. The problem with BBDB, or
|
|
;; keeping up a Bibl-mode file, is that you have to use different
|
|
;; functions to record the data, and it always takes time to stop what
|
|
;; you're doing, format the data in the manner expected by that
|
|
;; particular data interface, and then resume your work.
|
|
;;
|
|
;; With "remember", you just hit `M-x remember' (you'd probably want
|
|
;; to bind this to an easily accessible keystroke, like C-x M-r), slam
|
|
;; in your text however you like, and then hit C-c C-c. It will file
|
|
;; the data away for later retrieval, and possibly indexing.
|
|
;;
|
|
;; Indexing is to data what "studying" is in the real world. What you
|
|
;; do when you study (or lucubrate, for some of us) is to realize
|
|
;; certain relationships implicit in the data, so that you can make
|
|
;; use of those relationships. Expressing that a certain quote you
|
|
;; remembered was a religious quote, and that you want the ability to
|
|
;; pull up all quotes of a religious nature, is what studying does.
|
|
;; This is a more labor intensive task than the original remembering
|
|
;; of the data, and it's typical in real life to set aside a special
|
|
;; period of time for doing this work.
|
|
;;
|
|
;; "Remember" works in the same way. When you enter data, either by
|
|
;; typing it into a buffer, or using the contents of the selected
|
|
;; region, it will store that data -- unindexed, uninterpreted -- in a
|
|
;; data pool. It will also try to remember as much context
|
|
;; information as possible (any text properties that were set, where
|
|
;; you copied it from, when, how, etc). Later, you can walk through
|
|
;; your accumulated set of data (both organized, and unorganized) and
|
|
;; easily begin moving things around, and making annotations that will
|
|
;; express the full meaning of that data, as far as you know it.
|
|
;;
|
|
;; Obviously this latter stage is more user-interface intensive, and
|
|
;; it would be nice if "remember" could do it as elegantly as
|
|
;; possible, rather than requiring a billion keystrokes to reorganize
|
|
;; your hierarchy. Well, as the future arrives, hopefully experience
|
|
;; and user feedback will help to make this as intuitive a tool as
|
|
;; possible.
|
|
;;
|
|
;; * Future Goals
|
|
;;
|
|
;; This tool hopes to track (and by doing it with as little new code
|
|
;; as possible):
|
|
;;
|
|
;; - The raw data that gets entered
|
|
;;
|
|
;; - The relationships between that data (either determined
|
|
;; implicitly by parsing the input, or explicitly by the user's
|
|
;; studying the data).
|
|
;;
|
|
;; - Revisioning of the data
|
|
;;
|
|
;; - Where it came from, and any context information that can be
|
|
;; programmatically determined.
|
|
;;
|
|
;; - Allowing particular views of the initially amorphous data pool
|
|
;; (ala the Xanadu concept).
|
|
;;
|
|
;; - Storage of the data in a manner most appropriate to that data,
|
|
;; such as keeping address-book type information in BBDB, etc.
|
|
;;
|
|
;; * Using "remember"
|
|
;;
|
|
;; As a rough beginning, what I do is to keep my .notes file in
|
|
;; outline-mode format, with a final entry called "* Raw data". Then,
|
|
;; at intervals, I can move the data that gets appended there into
|
|
;; other places. But certainly this should evolve into an intuitive
|
|
;; mechanism for shuffling data off to its appropriate corner of the
|
|
;; universe.
|
|
;;
|
|
;; To map the primary remember function to the keystroke F8, do the
|
|
;; following.
|
|
;;
|
|
;; (autoload 'remember "remember" nil t)
|
|
;;
|
|
;; (define-key global-map [f8] 'remember)
|
|
;;
|
|
;; * Feedback
|
|
;;
|
|
;; If Emacs could become a more intelligent data store, where
|
|
;; brainstorming would focus on the IDEAS involved -- rather than the
|
|
;; structuring and format of those ideas, or having to stop your
|
|
;; current flow of work in order to record them -- it would map much
|
|
;; more closely to how the mind (well, at least mine) works, and hence
|
|
;; would eliminate that very manual-ness which computers from the very
|
|
;; beginning have been championed as being able to reduce.
|
|
;;
|
|
;; Have you ever noticed that having a laptop to write on doesn't
|
|
;; _actually_ increase the amount of quality material that you turn
|
|
;; out, in the long run? Perhaps its because the time we save
|
|
;; electronically in one way, we're losing electronically in another;
|
|
;; the tool should never dominate one's focus. As the mystic
|
|
;; Faridu'd-Din `Attar wrote: "Be occupied as little as possible with
|
|
;; things of the outer world but much with things of the inner world;
|
|
;; then right action will overcome inaction."
|
|
;;
|
|
;; * Diary integration
|
|
;;
|
|
;; To use, add the following to your .emacs:
|
|
;;
|
|
;; ;; This should be before other entries that may return t
|
|
;; (add-to-list 'remember-handler-functions 'remember-diary-extract-entries)
|
|
;;
|
|
;; This module recognizes entries of the form
|
|
;;
|
|
;; DIARY: ....
|
|
;;
|
|
;; and puts them in your ~/.diary (or remember-diary-file) together
|
|
;; with an annotation. Dates in the form YYYY.MM.DD are converted to
|
|
;; YYYY-MM-DD so that diary can understand them.
|
|
;;
|
|
;; For example:
|
|
;;
|
|
;; DIARY: 2003.08.12 Sacha's birthday
|
|
;;
|
|
;; is stored as
|
|
;;
|
|
;; 2003.08.12 Sacha's birthday
