@chapter Introduction

Planner is an organizer and day planner for Emacs.  It helps you keep
track of your pending and completed tasks, daily schedule, dates to
remember, notes and inspirations. It is a powerful tool not only for
managing your time and productivity, but also for keeping within easy
keystroke reach all of the information you need to be productive. It can
even publish reports charting your work for your personal web page, your
conscience, or your soon-to-be-impressed boss.

In fact, because it uses as its building blocks simple plain-text files,
it is an incredibly modular and flexible tool capable of shaping and
handling your personal information in ways whose variety is limited only
by your imagination. Because of this, Planner has a very active and
generous community who regularly share their innovations with each
other. Many of these modules and extensions are included in the archive
that you will download. Once you get the basics down, you'll probably
want to explore some of them. But as you read this manual and work with
Planner, keep in mind that the basic core is actually very simple, and
it might be worth spending time with just that before delving into the
customizations.

Because they are plain text with very few requirements, the organizer
pages kept by Planner can be as basic or as detailed as you
like. Your pages can be simple to-do lists with no more additional
information than what you would scrawl on a napkin, or they can be a
highly technical affair involving hyperlinks, embedded Lisp code,
appointment schedules and RSS feeds. As with so much in Emacs, it's
all up to you.

To get started with Planner, you first need to download it, and possibly
also the packages it depends on (@pxref{Installation}).

@node Installation, Overview, Introduction, Top

Planner depends on Muse. Information for downloading and installing
Muse can be found at
@url{http://www.mwolson.org/static/doc/muse.html}.

Make sure that you use the latest Muse release.  Development code might
prove unstable.

@subsection Installing from a Source Archive
@cindex source code archive, installing from

You can install Planner from the source archive packaged and
distributed directly by the maintainer. This archive is provided in
both @file{.tar.gz} and @file{.zip} format.

@enumerate
@item
Download and unpack either
@url{http://www.mwolson.org/static/dist/planner-latest.tar.gz} or
@url{http://www.mwolson.org/static/dist/planner-latest.zip}.

@item Edit your @file{~/.emacs} (@file{_emacs} on Microsoft Windows).

@example
;; Add the directories to your load path
(add-to-list 'load-path "/path/to/muse/lisp")
(add-to-list 'load-path "/path/to/planner")
(add-to-list 'load-path "/path/to/remember")

;; Load planner
(require 'planner)
@end example
@end enumerate

@subsubsection Updating Your Version

Download a new version and extract it over the old directory. Don't
forget to delete any byte-compiled files (@file{*.elc}) in the
directories so that the new code will be used.

@node Installing from Arch, Installing from Debian, Installing from a Source Archive, Getting the Files
@comment node-name,  next,  previous,  up
@subsection Installing from Arch
@cindex Arch repositories
@cindex Arch, installing from

Arch allows you to retrieve previous versions and select specific
features and bugfixes. Debian users can install Arch with @kbd{apt-get
install tla}. Users of other distributions should see
@url{http://regexps.srparish.net/www/}.

To get started with Planner using Arch, you'll need to run some initial
commands to register your local copy of the archive and retrieve the
files.

@example
# Register the Muse archive
tla register-archive http://www.mwolson.org/archives/2006

# Register the Planner archive
tla register-archive http://arch.gna.org/planner-el/archive-2006

# Get the Muse archive
tla get mwolson@@gnu.org--2006/muse--main--1.0 muse

# Download planner module into the planner/ subdirectory
tla get mwolson@@gnu.org--2006-planner-el/planner-el--devel--1.0 planner
@end example

Then add the following lines to your @code{~/.emacs}:

@example
;; Add the directories to your load path
(add-to-list 'load-path "/path/to/muse/lisp")
(add-to-list 'load-path "/path/to/planner")
(add-to-list 'load-path "/path/to/remember")

;; Load planner
(require 'planner)
@end example

You can also browse the Arch repository on the web at
@url{http://www.mwolson.org/cgi-bin/archzoom/archzoom.cgi/mwolson@@gnu.org--2006/planner}.

@subsubsection Updating Your Version
@cindex Arch, updating from

To stay up-to-date using Arch, here are some commands that might be
useful.

To list upstream changes not in local copy:

@example
# Change to the source directory you are interested in. Example:
cd muse/

# Display the summary of changes
tla missing --summary
@end example

To update to the latest version:

@example
cd muse; tla replay
cd ../planner; tla replay
cd ../remember; tla replay
@end example

Don't forget to delete any byte-compiled files (@file{*.elc}) in the
directories so that the new code will be used.

@node Installing from Debian, , Installing from Arch, Getting the Files
@comment node-name,  next,  previous,  up
@subsection Installing from Debian
@cindex Debian package

Debian packages for Planner, Muse, and Remember are available in Debian
proper as the @code{planner-el}, @code{muse-el}, and @code{remember-el}
packages, respectively.

If you wish to try experimental packages, add the following lines to
your @file{/etc/apt/sources.list}

@example
deb http://www.mwolson.org/debian/ ./
@end example

Then, do the following steps as root:

@example
apt-get update
apt-get install muse-el
apt-get install planner-el
@end example

@subsubsection Updating Your Version
@cindex Debian package, updating

If you installed Planner from Debian, do @kbd{apt-get update; apt-get
upgrade} to upgrade all packages that can be upgraded, or @kbd{apt-get
update; apt-get install planner-el} to upgrade just planner-el.

@node Creating Your Planner, Components, Getting the Files, Installation
@section Creating Your Planner

Now that you have installed the files for Planner and Muse, you need
to set some options to create your first planner.

Muse thinks in terms of projects. Each project consists of a group of
documents and certain information associated with these
documents. Planner is organized as a project within Muse. So, you need
to tell Muse a bit about it.

Add something like the following code to your @file{.emacs} file.

First, give your new Planner project a name. In this case, we use the
name, ``WikiPlanner''.

@example
(setq planner-project "WikiPlanner")
@end example

Next, add an entry for your project to Muse's master list of
projects. Don't forget to use your own name here in place of
``WikiPlanner'' if you have chosen something different.

@example
(setq muse-project-alist
      '(("WikiPlanner"
         ("~/Plans"           ;; where your Planner pages are located
          :default "TaskPool" ;; use value of `planner-default-page'
          :major-mode planner-mode
          :visit-link planner-visit-link)

         ;; This next part is for specifying where Planner pages
         ;; should be published and what Muse publishing style to
         ;; use.  In this example, we will use the XHTML publishing
         ;; style.

         (:base "planner-xhtml"
                ;; where files are published to
                ;; (the value of `planner-publishing-directory', if
                ;;  you have a configuration for an older version
                ;;  of Planner)
                :path "~/public_html/Plans"))))
@end example

This code should work fine as-is for you as long as the directories
you see exist, and as long as you have no other Muse projects besides
your planner.

The first directory (@file{~/Plans}) is the directory where the
source files for your planner will reside. This is the directory where
you will actually visit files and edit them.  These files must have a
``.muse'' extension.

The second directory (@file{~/public_html/Plans}) is the directory where
your planner files will be published by Muse as XHTML.

After you have added this code, make sure to either evaluate it or
restart Emacs.

@node Components, Advanced Installation, Creating Your Planner, Installation
@comment node-name,  next,  previous,  up
@section Components

Now that you have the archive, let's look at what's in it.

There should be three directories, named @file{planner}, @file{muse} and
@file{remember}.

In the @file{planner/} directory, you'll see many files with names like
@file{planner-gnus.el}. These are extra modules and extensions for
Planner, which you can use to tailor Planner to fit your desired
planning and information management habits.

In the @file{muse/lisp} directory, you'll see many files with names like
@file{muse-blosxom.el}. As in @file{planner/}, these are optional
modules and extensions.

A minimal working installation includes just @file{planner/planner.el}.

You need @file{planner.el} because it provides the core functions for
handling tasks, notes, and page navigation. You need @file{Emacs Muse}
because it provides the functions used to display your pages (both in an
emacs buffer and as HTML), and for connecting them to each other. More
specifically, it enables you to have hyperlinks and formatting in your
emacs buffers even though the actual files you are working with are
saved in plain text. These abilities are used in Planner to format your
planner pages the way you like, to create links from your tasks and
notes to the materials and projects they refer to, and to optionally
``publish'' your pages in different formats, including HTML.

In the @file{remember/} directory are files related to
RememberMode. RememberMode does not depend on Planner or Muse, but works
best with Planner installed. It is not required in order to use Planner,
but it is used by many Planner users to record notes and information to
their planner pages.

If you are curious, you can open each file in these directories and read
the comments at the top, to get an idea of what each extension is used
for. They are also all detailed later in this manual.

Once you decide you want to keep Planner around for a while, there
are two additional steps you can take to make using it easier and more
efficient. These steps are optional.

@itemize

@cindex @file{remember.el}
@cindex @file{remember-planner.el}
@item You can install @file{remember.el} and @file{remember-planner.el}
so that you can create Planner notes from anywhere. See the
documentation at
@uref{http://sacha.free.net.ph/notebook/doc/dev/remember/} for more
information.

@cindex installing the info file
@cindex @file{planner-el.texi}, installing
@cindex @file{planner-el.info}, installing
@item You can make this document, the Planner info file, appear in
the index of info files you see when you type @command{M-x info} or
@kbd{C-h i} in Emacs. The instructions for doing this vary depending
on whether you have permission to edit certain files on your
system. Follow the instructions in @ref{Installing an Info File, ,
,texinfo, Texinfo}, using something like:

@example
* Planner: (path/to/planner/Planner). Organizer/day planner
for Emacs.
@end example

for the new entry in the info @file{dir} file.

@cindex byte compiling
@item You can byte-compile @file{planner.el}, @file{Muse},
@file{remember.el}, or any of the optional modules you frequently use,
in order to improve the speed of their execution. Basically, all you
need to do is change to the directory of each project and run
@command{make} from the command line. To read more detail about byte
compilation, see @ref{Byte Compilation, , ,elisp, Emacs Lisp Reference
Manual}.

@chapter Overview

Planner is a plain-text hyperlinked personal information manager
for Emacs that helps you keep track of tasks, notes, and other
information. People use Planner to support different ways of planning
one's day, from Franklin-Covey and David Allen's Getting Things Done
to home-brew hacks. Planner is even used to manage information not
normally handled by a personal information manager, like bugtracking,
time tracking, and team data. If you start by using Planner as a basic
TODO and notes manager, you might find other ways it can help you
improve your process.

You can use Planner to keep track of your tasks, schedule, notes,
and other information you want to store in hyperlinkable text files.
You can get the most benefit out of a personal information manager if
you use it everyday. Most people add @code{(plan)} to the end of their
@file{~/.emacs} so that Planner shows today's schedule and
unfinished tasks whenever Emacs starts. If you leave your Emacs
running for more than 24 hours, try to get into the habit of running
@code{plan} at least once a day.

Because your time is important, Planner tries to minimize
distractions, making it easier for you to jot down tasks and notes
without being distracted from your work. People often make tasks based
on the current buffer, so Planner tries to create hyperlinks to
whatever you're looking at so that you can jump back to it easily. The
@ref{Getting Started} tutorial will show you how to set that up for
both tasks and notes.

The customizability of Planner means you can make your personal
information manager truly personal. Planner strives to be as flexible
as possible, and we would love to adapt Planner to fit your needs.
Browse through our mailing list (@pxref{Getting Help}) to
find out how other people are using Planner, and post your feature
requests and bug reports there!

Planner is just a tool. It does not dictate a particular way of
planning, although it supports some ways better than it supports
others. If you want to take some time thinking about planning, read
the following reflections for inspiration and ideas. On the other
hand, if you want to hit the ground running, see @ref{Getting
Started}. If you already have a specific way of planning in mind,
check out @ref{Sample Configuration Files}.

@cindex philosophy of planning

This is a slightly edited and updated version of an essay by John
Wiegley. Read it if you want to get some insights into one way of
planning. You can skip this if you want to go straight to planning
your day.

What is planning?  It can be a nebulous thing to define.  In its
essence, however, it is very simple: it's how we achieve our dreams.

Our days are filled with time, and hence with actions, whether they
be of a mental or physical sort.  But there are two kinds of
action: reactive and creative.  Reactive action is a response to
the environment, a reaction to stimulus.  Had we enough instincts
to ensure survival, we could live according to this kind of action
alone.  It is a mode of behavior we share with every living
species.

The opposite to reactivity is creativity, when we decide upon a
course of action that is a wholly a product of personal choice.  We
then make decisions as to the steps needed to make this wish a
reality.  This is planning.  Planning is essentially a creative
endeavor at every step.

First, create the idea, what you want to achieve.  Very short-term
ideas do not need much more than thinking about how to do it.  But
long-term ideas require planning, since the mind cannot contain all
of the details.

Second, decide how the idea maps into the circumstances you find
yourself in.  Some environments will assist your plan, others
hinder it.  But step by step, identify every barrier to the
realization of your idea, and devise a countermeasure to overcome
it.  Once you've mapped things out from beginning to end,
accounting for unknowables as best you can, you now have your plan.

Third is to break the stages of the plan into parts that are not
overwhelming in their complexity.  It is at during this phase that
a plan is turned into task items, each to be accomplished within
the span of one day's time.  If a task requires several days, break
it up further.  The smaller it is, the less your mind will recoil
from attempting it.

Fourth is to monitor your progress, identifying problems and
correcting for them as you go.  Some plans start out unachievable,
and remain that way indefinitely, due to a simple lack of
observation.  If nothing is working for you, change it.  Otherwise,
your plan is merely a well-crafted wish.

Fifth is just to do the work, and be patient.  All good plans take a
great deal of time, and *cannot* happen immediately.  The groundwork
must be laid for each step, or else it will rest on an unsecure
foundation.  If you follow your plan doggedly, applying some time to
it each day or week, it @emph{will} happen.  Remember the story of the
tortoise and the hare.  I've even written a short essay on the
necessity of gradual accomplishment, which can be found at
@url{http://emacswiki.org/johnw/essays/node2.html}.

How can this software help?  Computers are ideal for manipulating
information, since they allow you to change things without erasing
or rewriting.  And since all plans change quite a bit during their
implementation, a planning program can be very helpful.

Start by adding the following to your @file{.emacs} (or @file{_emacs}):

@example
(load "planner")
@end example

Now, conceive your idea.  I can't believe there's nothing you want
from life.  More peace, time to enjoy the world, an end to war?
Everyone wants something.  Search deeply, and you will find
countless unhoped wishes lurking therein.  Choose one for now, and
think on it for a while.

Then open a file (using @kbd{C-x C-f}) within the directory named by
@code{planner-directory}.  Emacs will automatically recognize this file
as a planner file.  Name the file after your plan, such as
@file{BetterHealth}.

Choose an idea you really want to accomplish.  Struggle to
differentiate between the things you want because others want them,
and the things you want for yourself.  It takes quite an effort, and
may require a long time before you notice the difference.  Many people
want to be more healthy to be more attractive, which is an externally
driven goal.  Unless @emph{you} really want to accomplish what you
envision, the odds are you will fail.  Only our own wishes and dreams
possess enough personal energy to see themselves to fruition.  What
happens to many of us is simply that we never become conscious of
these dreams: what we love, what we desire most.  When I talk to
friends, so much of what I hear is things they want because they feel
they should want them.  There's just not enough energy there to pursue
a good plan, because nearly all of it is negative energy.

Do you know what you really want?  Don't worry, many people don't.
It's not a question anyone really wants us to pursue, because often
we don't want what others do; it doesn't contribute to the social
welfare, and all that nonsense.  Somehow we always forget that
what's good for the social welfare now, was someone else's crazy
dream a hundred years ago.  The human aversion to fundamental
change is always one's greatest enemy, so don't waste any time
getting bitter about it.

For the sake of argument I assume you really do want to be
healthier, because you've fallen in love with the ideal of purity,
or you understand the connection between your physical self and the
world around you, and how this can open up your spirit to desiring
more.  I assume.  :)

So you're in a Wiki file called @file{BetterHealth}.  Start typing.
Type anything related to your idea: what you think about it, your
ideas on it, @emph{and especially what the end will look like}.  If
you can't visualize the end, you can't plan, since planning is about
drawing a line between now and then.

When you've typed enough to gain a vision of your goal, start
drafting what the possible intermediate steps might be.  Then stop,
get up, walk around, enjoy life, and come back to it.  Taking a
long time at the beginning is not a bad idea at all, as long as
it's not forever.

As you chew on your idea, it will begin to become more and more
concrete.  You'll have ideas about the smallest pieces, and ideas
about the biggest pieces.  Keep going until it starts to take shape
before you, and you can see yourself in your mind's eye moving from
the present into the future.  Write down this progression, and the
sorts of things you might encounter along the way.

As you continue, you'll naturally discover discrete phases, or
``milestones'' as managers love to call them.  These are very
important, because they let you know you're making progress.  I
recommend having a big party with friends every time you achieve a
milestone.  A typical plan might have between three and ten.

Between the milestones are the bigger pieces of your plan.  Name
these pieces using MixedCase words, and you'll notice that Emacs
colors and underlines them for you.  Like, FindGoodGym.  Hit return
on this highlighted word, and you'll find yourself in another,
blank file.  In this file, start drafting your sub-plan, just as
you did with the larger plan.  You should find it easier now, since
the scope is smaller.

As you break down further, you'll notice simple little things that
need to get done.  These are your tasks.  Every plan is a
succession of tasks.  The difference from reactivity is that each
task is part of the larger plan. This is what it means to be
systematic: that everything you do helps further your plan.  If you
have tasks in your day that contribute to no plan, they are
reactive.  Of course, life is full of these, but don't let them
take up more than 20% of your day.  If you allow yourself to be
dominated by reactive tasks, you'll regret it at the end of your
life.  I don't know this personally, but I do know that striving
for one's dreams -- and seeing them come to fruition -- is the
greatest joy a man can possess.  It is the essence of freedom, of
living, of creation.  Reactivity is the opposite of this, and
serves only to drain our energy and slacken our spirits.

Now that you've thought of a simple task, type @kbd{C-c C-t}. This
will ask for a brief description of the task, and when you plan to do
it. If you hit @key{RETURN} at the question @samp{When}, it assumes
you mean today. It will also pop up a three-month calendar at this
question, so you can see where your free days are. Make sure you set
the variable @code{mark-diary-entries-in-calendar} to @samp{t} in your
@file{.emacs} (or @file{_emacs}) file. This way, you can see which
days your appointments fall on. (Read about the Emacs Calendar and
Diary in @ref{Calendar/Diary, , , Emacs, GNU Emacs Manual}.)

@example
(setq mark-diary-entries-in-calendar t)
@end example

Once your task is in there, go back to your plan and keep
generating more tasks.  Generate them all!  Fully describe---as
tasks---everything necessary to bring your sub-plan to completion.
Don't create tasks for the other sub-plans.  You may have good idea
of what they'll look like, but don't bother rendering them into
tasks just yet.  Things will change too much between now and then,
for that to be a good use of your time.

Is your sub-plan now rendered into all of the tasks necessary to
reach your first milestone?  Great!  That is the purpose of
planner.el.  The rest is really up to you.  If you find that you
keep putting things off, and never do them, that's the surest sign
you're planning for someone else's dream, and not your own.

Here are some of the things planner.el can do, to help you manage
and track your tasks:

At the beginning of every day, type @kbd{M-x plan}.  This will jump
you to the top of the most recent task list before today.  If you
skipped a bunch of days, you'll have to open up those files on your
own.

Probably some of the tasks that day won't be finished -- that's OK.
Learning to properly estimate time is a magical, mystical art that few
have mastered.  Put your cursor on those undone tasks, and type
@kbd{C-c C-c}.  This will move them into today's task page.  You can
jump to today's task page at any time by typing @kbd{C-c C-n} (from a
Wiki or planning page).  I heartily recommend binding @kbd{C-c n}, to
jump you to this page from anywhere:

@example
(define-key mode-specific-map [?n] 'planner-goto-today)
@end example

As you look at your task sheet each day, the first thing to do is to
``clock in'' to one of them.  This isn't necessary, and is only
helpful if you're around your computer a lot.  But by typing @kbd{C-c
C-i} (assuming you have my @file{timeclock.el} on your load-path), it
will log the time you spend working on your sub-plan (@pxref{Time
Intervals, , , Emacs, GNU Emacs Manual}).  This is helpful for viewing
your progress.  Type @kbd{C-c C-o} to clock out.

@kbd{C-M-p} and @kbd{C-M-n} will move a task up and down in priority.
Priority is represented by a letter A through C.  'A' tasks mean they
must be done that day, or else your plan is compromised and you will
have to replan.  'B' means they should be done that day, to further the
plan, otherwise things will be delayed.  'C' means you can put off the
task if you need to, although ultimately it will have to be done.

For reactive tasks, the letters mean something different: 'A' means
you must do it today, or somebody will roast your chestnuts over an
open fire.  'B' means you should do it today, or else someone will
be practicing patience at the day's end.  'C' means no one will
notice if you don't do it.

Again, reactive tasks are ENEMIES OF PLANNING.  Really, until you
see them that way, circumstances will push you around and steal
your life away.  We have only so many years to use, and everyone is
greedy to take them.  It's insidious, almost invisible.  A healthy
dislike of reactivity will do wonders for organizing your affairs
according to their true priority.

The last word that needs to be said concerns ``roles''.  Every person
stands in several positions in his life: husband, employee, manager,
etc.  These roles will tend to generate tasks not associated with any
immediate plan, but necessary to maintain the health and functioning
of the role.  My suggestion is to keep this the smallest possible
number, and fulfill those that remain well.  How you decide to
apportion your time between pursuing grand designs, and fostering deep
relationships, is a personal matter.  If you choose well, each will
feed the other.

I mention this to point that reactivity is something not
exclusively associated with tasks that have no master plan, because
being a father, for example, is something that rarely proceeds
according to orderly plans.  But the role of father itself is its
own plan, whose goal is ``to be the best one can'', and whose
component tasks are spending time on whatever comes up.  It is, in
a sense, an implicit plan.  But reactive tasks follow no plan at
all; they are parasites of time that suck the spirit away, whereas
properly chose roles actually help fulfill one's own inner needs.
At least, this is what I believe.

@defun plan force-days
Start your planning for the day, beginning with the last day's tasks.

If @code{planner-carry-tasks-forward} is non-nil, find the most recent
daily page with unfinished tasks and reschedule those tasks to
the current day.  If @var{force} is non-nil, examine all past daily
pages for unfinished tasks.

If @code{planner-carry-tasks-forward} is nil, visit the most recent
daily page.  If a daily page for today exists, visit that instead.

If @var{force-days} is a positive integer, scan that number of days.
If @var{force-days} is @samp{t}, scan all days.

Why I Use Planner, by Sacha Chua

I thought about why I liked Planner. Planner as a TODO manager
isn't particularly special. Although I can assign tasks to categories
and see a breakdown of what projects are taking up my time, Evolution
and Microsoft Outlook provide more powerful task support. In other
task managers, you can e-mail tasks, assign multiple categories and
fill in all sorts of metadata. You can even synchronize your tasks
with devices like a phone or PDA. So why use Planner?

I realized that integration into my way of life and automatic context
clues are what really make planner tasks worth it for me. I don't have
to switch to another application to create a task. I can just hit a
keyboard shortcut. Planner uses a minibuffer to get the task
description. My windows are not rearranged in any way, and I can look
at the data that's relevant to a task. Not only that, tasks
automatically pick up context clues, like whom I'm talking to on IRC
or the file I'm editing at the moment. This cuts down on the explicit
context I need to include and makes it easier for me to bring up the
task again.

As a scheduler, Planner is also not particularly distinguished.
Sure, it can display my @file{~/diary}, but for that matter so can
@kbd{M-x diary}. Evolution and Outlook can give me a more graphical
view of my time, sync with my PDA, and coordinate my schedule with
other people. Those applications support detailed schedule entries
with powerful cyclic options. On the other hand, Planner gives me
a personal, plain text view and (at least the way I use it) requires
me to edit a separate file to add new appointments. (I've defined a
few shortcut keys to deal with this.) However, it does have one
advantage---my schedule is always loaded. I used to use Outlook on
Windows, but having my schedule in a separate application meant that I
actually looked at it very rarely, as I had turned off reminders
because they got annoying.

Planner's notes, however, are what really convinced me. I can hit
a keyboard shortcut from anywhere and type my notes into a buffer
which automatically keeps context information. After typing the note,
I can then categorize it. I think that the critical thing here is that
interruptions---fleeting thoughts---don't break my flow. I can just
pop up a remember buffer, stow that thought away somewhere, and go
back to it whenever I want. In contrast, creating a note in Outlook
means switching out of my application, making a couple of keystrokes,
typing the note in, and then switching back. The context switches make
it hard to keep track of where I am and what I'm supposed to remember.
Not only that, I need to enter context by hand. Even though I can
color my notes and reorganize them in Outlook, I find the context
switch too expensive. I used to keep notes in other knowledge
management tools as well. Some applications allowed me to
drag-and-drop links into the current note, and that was cool. But that
required a manual action, and those applications didn't feel
integrated into my way of working. (Note: You'll need remember.el for
this.)

I guess that's why I like Planner. Unlike other organizers which
don't know anything about the applications I use, Planner tries
its best to integrate into the way I work, and it's easy to extend.
Fortunately I do almost all my work in Emacs, so I can think of my
organizer as integrated into my e-mail client, Internet Relay Chat
client, web browser, file editor and even games. It automatically
picks up context clues from these applications and allows me to easily
jump back to relevant files. It doesn't distract me. It allows me to
key in data and then it gets out of my way.

(That said, it's perfectly okay to use Planner even if you don't live
in Emacs.)

The processing that happens in the background is a bonus, and
publishing my task list and notes online has greatly helped me. It
gives other people a way to see what I'm working on and what I've
planned for the future. Occasionally people write in with additional
resources and helpful tips. (Again, this is purely optional. Many
people don't publish their planner pages. Other people use really
fine-grained access control.)

I think the greatest feature of Planner, though, is its user
community. Because Planner can be easily modified, we can experiment
with a lot of new ideas quickly, and we can tailor Planner to fit our
needs. I love checking my @samp{emacs-wiki-discuss} mail and finding
out how people have tweaked Planner or would like to tweak Planner,
and I've learned a lot by exchanging reflections on organizing one's
life.

I really wasn't an organization freak before I started using Planner.
I often forgot to do my homework or answer important mail. I still
procrastinate now, but at least it's all being kept track of
somewhere! I also really like how Planner lets me to gradually improve
how I'm doing things, and I feel I've come a long way.

Please try it out! We'd love to hear how Planner can become
@emph{your} personal information manager.

@node Getting Started, More about Planner, Overview, Top
@comment  node-name,  next,  previous,  up
@chapter Getting Started

At the end of this tutorial, you will be able to use Planner and
related modules to keep track of your tasks, schedules and notes, all
within the convenience of Emacs.

There are two kinds of pages in a Planner wiki. Day pages show tasks,
schedule, and notes for the day, while plan pages organize related tasks
and notes into a single page.

If you have not yet added planner to your @file{~/.emacs}, add the
following lines:

@example
(add-to-list 'load-path "/path/to/muse/lisp")
(add-to-list 'load-path "/path/to/planner")
(add-to-list 'load-path "/path/to/remember")
(require 'planner)
@end example

This will bring up the most recent day page with unfinished tasks or
create a new day page if necessary. By default, planner pages are
stored in @samp{~/Plans} (@code{planner-directory}).

@menu
* Tasks::                       
* Schedule::                    
* Notes::                       
* Hyperlinks::                  
* Example Page::                
* Review::                      
@end menu

@node Tasks, Schedule, Getting Started, Getting Started
@section Tasks

Let us start by creating a task labelled

@example
Join http://lists.nongnu.org/mailman/listinfo/emacs-wiki-discuss
@end example

From anywhere (even this info buffer!), call @kbd{M-x
planner-create-task-from-buffer} to create a new task. Fill in the
description and choose a date by:

@itemize
@item typing 1 - 31 to put the task on that day of the month,
@item accepting the default (today) by pressing RET,
@item selecting the date with mouse-1,
@item
typing +n (where in is an integer) to schedule the task in n days time,
or
@item typing nil to make an undated task.
@end itemize

For now, accept the default (@samp{today}) by pressing @key{RET}.

You will then be prompted for a plan page. Plan pages gather related
tasks and notes, giving you an overview of what you've done so far.
You can accept the default TaskPool, create your own plan page, or
specify nil to make a task that is not associated with a plan page.
For now, accept the default (@samp{TaskPool}) by pressing RET.

You have created your first task. View today's page with
@kbd{M-x planner-goto-today}. You will see a line of the form

@example
#B  _ Join http://lists.nongnu.org/mailman/listinfo/emacs-wiki-discuss (TaskPool)
@end example

If you created the task from this page, then there will be an additional
annotation:

@example
#B  _ Join http://lists.nongnu.org/mailman/listinfo/emacs-wiki-discuss : Tasks (TaskPool)
@end example

The URL, @samp{TaskPool} and @samp{Getting Started} are
hyperlinks. You can use TAB and S-TAB to navigate between them and RET
to follow the link.

Create more tasks using @kbd{M-x planner-create-task-from-buffer}.
This is bound to @kbd{C-c C-t} in @code{planner-mode} pages
for your convenience. For example, create the following tasks:

@itemize
@item
@samp{Describe my current way of working and how I would like to work},
for three days from now (@samp{+3}),
@item
@samp{Learn how to schedule a task}, an undated task (@kbd{nil}) on the
TaskPool page,
@item
@samp{Browse through the Planner info manual} for today (@kbd{.} or
accept the defaults), and
@item
@samp{Add (plan) to the end of my [[~/.emacs]]} for today, but without a
plan page (specify @kbd{nil} at the plan page prompt)
@end itemize

Tip: I bind planner-create-task-from-buffer to "F9 t" so that I can
easily call it from anywhere. You can do that with this elisp fragment:
@code{(global-set-key (kbd "<f9> t") 'planner-create-task-from-buffer)}

Next, visit the TaskPool by:

@itemize
@item
@key{TAB}-bing or using the cursor and typing @key{RET} to follow the
link,
@item @kbd{C-x C-f TaskPool RET} to use @code{find-file}, or
@item @kbd{C-c C-f TaskPool RET} to use @code{muse-project-find-file}
@end itemize

You can see an overview of the tasks as scheduled on different days.
Unlike many personal information managers that store all of your data
in one file and then perform magic in order to present different
views, Planner uses plain text files. The data is duplicated and kept
updated by functions. This makes it simpler and easier to modify,
because what you see is (almost) what you get. On the other hand,
you'll need to get used to either editing both files, or using the
built-in functions for editing and updating files. If you prefer not
to work with linked tasks, you can configure Planner to use only plan
pages or use only day pages.

The TaskPool page should list the tasks you created earlier. Go to the
one named Learn how to schedule a task . Type @kbd{C-c C-c}
(@code{planner-copy-or-move-task}) to schedule the task. Type RET to
accept the default (today). Go to the day page by following the link
or calling @kbd{M-x planner-goto} (@kbd{C-c C-j C-d} or the menu bar);
you will see the newly-created task there. You can also use @kbd{C-c
C-c} (@kbd{planner-copy-or-move-task}) to reschedule a task to an
earlier or later date.

Well, that task is done. To mark the task as completed, type @kbd{C-c
C-x} (@code{planner-task-done}). You can also edit the status manually
(change _ to X) as long as you remember to call @kbd{M-x
planner-update-task} to update the link page as well. Updating relies on
the task description being the same, so do not edit this manually.

Quick summary of commands:

@itemize
@item
Go to today's page: @kbd{M-x plan} to carry unfinished tasks forward, or
@kbd{M-x planner-goto-today} to just go to today's page.
@item
Create a task: @kbd{C-c C-t} (@code{planner-create-task-from-buffer}),
or type a task manually (call M-x planner-update-task if the task is
linked)
@item
Mark a task as done: @kbd{C-c C-x} (@code{planner-task-done}), or edit
the task and call @kbd{M-x planner-update-task}
@item Edit a task description: @kbd{M-x planner-edit-task-description}
@item Reschedule a task: @kbd{C-c C-c} (@code{planner-copy-or-move-task})
@item
Reschedule many tasks: Mark a region and use @kbd{M-x
planner-copy-or-move-region}
@item
Change the plan of a task: @kbd{M-x planner-replan-task}, or @kbd{C-c
C-c} (@code{planner-copy-or-move-task}) with a plan page
@item Delete a task: @kbd{M-x planner-delete-task}
@item
Reorder tasks: @key{M-p} (@code{planner-raise-task}) and @key{M-n}
(@code{planner-lower-task}), or normal editing commands like kill and
yank
@item Change task priorities (@samp{#A} > @samp{#B} > @samp{#C}):
      @key{C-M-p} (@code{planner-raise-task-priority}) and
      @key{C-M-n} (@code{planner-lower-task-priority}),
      or edit the task and call @kbd{M-x planner-update-task}.
@end itemize

You can save your tasks with @kbd{C-x C-s} the same way you save any
other file, or Emacs will prompt you to save it when you exit.

@node Schedule, Notes, Tasks, Getting Started
@comment  node-name,  next,  previous,  up
@section Schedule

This is free-form. You can put anything you want into this, or remove
it from @code{planner-day-page-template} entirely. Some people use it
to keep track of their plans for the day with tables like this:

@example
hh:mm | hh:mm | activity
hh:mm | hh:mm | activity
hh:mm | hh:mm | activity
@end example

Remember, Planner files are just plain text. You can add new sections
or remove old ones, or use the suggested sections for entirely
different activities.

You may be interested in @file{remember-planner.el}, part of the
Remember package. @code{remember-planner.el} makes it easy to create
notes from anywhere in Emacs, and it uses the same hyperlink-sensing
code that Planner uses. Notes added by remember-planner.el look like
this:

@example
.#1 Headline 00:00
Body
@end example

and are outlined at the H2 level in published HTML.

If you include the following in your @file{~/.emacs}:

@example
(require 'remember-planner)
(setq remember-handler-functions '(remember-planner-append))
(setq remember-annotation-functions planner-annotation-functions)
@end example

you can easily create context-aware notes. @kbd{M-x remember} will
create a dedicated buffer for you to fill in your note. If Planner
recognizes the buffer as one with context then it will include a
hyperlink at the bottom. The first line is used as a title, so make it
short and meaningful. The rest of the text will be used as the body of
the note. Try it now by creating a note, perhaps about things you'd
like to remember from this tutorial.

Typing @kbd{C-c C-c} after composing will prompt for a plan page to
put this on, with auto-completion. By default, notes will go on
today's page only. If you specify a plan page, the note will go on
today's page and on the plan page. Let's try specifying
@samp{TaskPool} for the note.

If you look at today's page, you'll find a timestamped note that links
to @samp{TaskPool}. Likewise, @samp{TaskPool} contains a note that
links to today's page. Because the text is copied, changes in one will
not be automatically reflected in the other. To update the linked page
after editing a note, use @kbd{M-x planner-update-note}. To change the
plan page of a note, use @kbd{planner-replan-note}.

@node Hyperlinks, Example Page, Notes, Getting Started
@section Hyperlinks
@cindex hyperlinks

Planner automatically creates context-sensitive hyperlinks for your
tasks and notes when you use @code{planner-create-task-from-buffer}
and @code{remember}.

Blue links indicate URLs and Planner pages that already exist. Red links
indicate Planner pages that have not yet been created.

Middle-click or type @key{RET} on any link to view the link in the
current window. Shift-middle-click or type @key{S-RET} to view the
link in another window. @key{TAB} goes to the next link, while
@key{S-TAB} goes to the previous one.

You can pick up hyperlinks using the @code{planner-annotation-as-kill}
function.

@defun planner-annotation-as-kill
Create a context-sensitive hyperlink for the current buffer and copy
it to the kill ring. When called with a prefix argument, prompt for
the link display name.
@end defun

You can then paste it into any Planner buffer by using @kbd{M-x yank}
or the keyboard shortcut.

Hyperlinks are a powerful feature of Planner. You can use them to
hyperlink to mail, news, Web pages, and even IRC connections. See the
section on @ref{Managing Your Information} to find out how to enable
support for various parts of Emacs. Want to add a new hyperlink
scheme? Check out the source code for examples or ask on the mailing

@section Starting with Day Pages

@command{planner-goto-today} opens today's page.  Day pages are named
@samp{YYYY.MM.DD} and contain your notes for the day.

You should see a file that looks like this:

@example
* Tasks


* Schedule

* Notes
@end example

You can type anything you want into this file.  You can add or delete
sections.  When you save, Emacs stores your information in
@code{planner-directory}.

Use the following commands to navigate through day pages:

@defun plan
Start planning the day.  If @code{planner-carry-tasks-forward} is
non-nil, copy the most recent unfinished tasks to today's page, else
open the most recent page.
@end defun

@defun planner-goto (@kbd{C-c C-j C-d})
Prompt for a date using a calendar pop-up and display the
corresponding day page.  You can specify dates partially.  The current
year and month are used if omitted from the input.  For example, if
today is 2004.05.05, then

@itemize
@item @kbd{+1} is one day from now, or @samp{2004.05.06}
@item @kbd{-1} is one day before now, or @samp{2004.05.04}
@item @kbd{12} is equivalent to @samp{2004.05.12}
@item @kbd{8.12} is equivalent to @samp{2004.08.12}
@item @kbd{2005.08.12} is a full date specification
@end itemize

In the calendar buffer, you can also left-click or press @key{RET} on
a date to select it.
@end defun

@defun planner-goto-today (@kbd{C-c C-j C-j})
Display today's page. Create the page if it does not yet exist.
@end defun

@defun planner-goto-tomorrow (@kbd{C-c C-j C-t})
Goto the planner page days @var{after} the currently displayed date.
If @var{days} is nil, go to the day immediately after the currently
displayed date.  If the current buffer is not a daily planner page,
calculate date based on today.
@end defun

@defun planner-goto-yesterday (@kbd{C-c C-j C-y})
Goto the planner page @var{days} before the currently displayed date.
If @var{days} is nil, go to the day immediately before the currently
displayed date.  If the current buffer is not a daily planner page,
calculate date based on today.
@end defun

@defun planner-goto-most-recent
Go to the most recent day with planning info.
@end defun

@defun planner-goto-previous-daily-page
Goto the last plan page before the current date.
The current date is taken from the day page in the current
buffer, or today if the current buffer is not a planner page.
Do not create pages if they do not yet exist.
@end defun

@defun planner-goto-next-daily-page
Goto the first plan page after the current date.
The current date is taken from the day page in the current
buffer, or today if the current buffer is not a planner page.
Do not create pages if they do not yet exist.
@end defun

@defun planner-goto-plan-page page
Opens @var{page} in the the @code{planner-project} Wiki.  Use
@code{planner-goto} if you want fancy calendar completion.
@end defun

@defun planner-show date
Show the plan page for @var{date} in another window, but don't select
it.  If no page for @var{date} exists, return nil.

@subsubsection Creating a Task
@cindex tasks, creating

You can create a task from any buffer in Emacs by invoking
@command{M-x planner-create-task-from-buffer}.

This command does more than just add an item to your list of tasks. It
also connects that item to some useful context information.

If you create a task while viewing any buffer other than a Planner
day page, Planner will associate the task with a hyperlink to that
buffer. Try it now by creating a task from this Info buffer.

@enumerate
@item @kbd{M-x planner-create-task-from-buffer}
@item
When prompted for the task name, enter @kbd{Learn how to change a task's
status} and press @key{RET}.

@item
When prompted for the date, press @key{RET} to schedule the task for
today.

@item
When prompted for the project page, press @key{RET} to accept the
default page of @samp{TaskPool}. This is a page for tasks not connected
to a larger plan.

@end enumerate

Planner prompts you for two pieces of information when you ask it
to create a task. First, it asks you when you would like to have the
task show up in your planner. If you would like it to be scheduled for
today, you can just hit @key{RET}. If you would like it to be
scheduled for some day during the current month, you can just enter
the date, without the month, like @samp{16}. If you would like it to
be scheduled for some day in a future month of the current year, you
can enter just the month and date, like @samp{06.16}. If you would
like to schedule something for next year, then enter the full date,
like @samp{06.16.2005}. If you do not want this task to appear on a
day page at all, you can enter @samp{nil}.

The second piece of information Planner asks for is the name of
the project to associate the task with. In the above example, you
associated the task with the project ``TaskPool'', which means that
you did not want to associate the task with a particular project or
goal in your life. Another way to do this is to answer the project
prompt by entering @samp{nil}. But instead, you might enter
@samp{LearnPlanner} as the project. This creates a new page called
``LearnPlanner'' in your planner directory and places an entry for the
task on that page.

The task then exists in two places: once on your day page, to show how
it fits into your daily work; and once on a project page, to show how
it fits into your larger projects and goals. In the future you might
add related tasks like, ``Memorize Planner keybindings''. These
tasks might be scattered over weeks or months worth of day pages, but
as long as you enter the same project name for each, you will have a
way to look at them all together on a single project page.

Planner also creates hyperlinks to enable you to easily move back
and forth between the day page system and the project page
system. Each task on a day page will have a hyperlink to its project
page. Each task on a project page will have a hyperlink to its day
page.

After using Planner for a while, you may find yourself with quite
a few project pages. Keep in mind that completion is enabled at the
project prompt when you create a task, so hitting @kbd{SPC} or
@kbd{TAB} at the prompt will show you a list of your current project
pages.

Once the task is created, you are returned to the buffer you were
working in again, Planner gets out of your way, and you can go on
about your business. Later on, when you decide to actually work on
that ``Memorize Planner keybindings'' task, you will be able to
follow the hyperlink from that task on your day or project page
directly to the relevant node in the Planner info file!

By default, @command{M-x planner-create-task-from-buffer} creates
medium-priority tasks, marked with the letter @samp{B}.  But you can
specify a particular priority or change the default (@pxref{Task
Priorities}).

You don't have to use @command{planner-create-task-from-buffer} to
create tasks. You can also create new tasks manually by typing them
directly on your day or project page in the format Planner expects. You
can even still create hyperlinks by using Muse formatting as you
manually type the new task. Keep in mind also that tasks do not have to
be linked to any other page.

For convenience, @command{planner-create-task-from-buffer} is bound to
@kbd{C-c C-t} in Planner buffers.  You can bind
@command{planner-create-task-buffer} to a shortcut key.  See the
manual for your Emacs distribution to find out more about keybinding.

@defun planner-create-task-from-buffer title date plan-page
Create a new task named @var{title} on @var{date} based on the current
buffer.

With a prefix, associate the task with the current planner page.  If
you create a task on a date page, you will be prompted for a plan
page.  If you create a task on a plan page, you will be prompted for a
day page.  If nil is specified, the task is created only on the
current page.

See @code{planner-create-task} for more information.

The new task is created at the top or bottom of the first block of
tasks on the scheduled day page (if any), depending on the value of
@code{planner-add-task-at-end-flag}.
@end defun

@defun planner-create-task title date annotation plan-page
Create a new task named @var{title} based on the current Wiki page.
If @var{date} is non-nil, makes a daily entry on @var{date}, else
makes an entry in today's planner page. It's assumed that the current
Wiki page is the page you're using to plan an activity. Any time
accrued to this task will be applied to that page's name in the
timelog file, assuming you use timeclock (@pxref{Time Intervals, , ,
Emacs, GNU Emacs Manual}). If @var{annotation} is non-nil, it will be
used for the page annotation. If @var{plan-page} is non-nil, the task
is associated with the given page.

With a prefix, associate the task with the current planner page.  If
you create a task on a date page, you will be prompted for a plan
page.  If you create a task on a plan page, you will be prompted for a
day page.  If nil is specified, the task is created only on the
current page.

You probably want to call @code{planner-create-task-from-buffer}
instead.

The new task is created at the top or bottom of the first block of
tasks on the scheduled day page (if any), depending on the value of
@code{planner-add-task-at-end-flag}.
@end defun

@subsubsection Task Priorities

You can set the priority of a task when you create it, rather than
waiting to adjust it after the fact. In order to do this, call the
function corresponding to the priority you want. You probably want to
bind these functions to some keys if you intend to use them much.

@itemize
@item @code{planner-create-high-priority-task-from-buffer}
creates a task with priority @samp{A}.

@item @code{planner-create-medium-priority-task-from-buffer}
creates a task with priority @samp{B}.

@item @code{planner-create-low-priority-task-from-buffer}
creates a task with priority @samp{C}.
@end itemize

Or, you can change the default priority of
@command{planner-create-task-from-buffer} by customizing
@var{planner-default-task-priority}.

You can actually use just one general priority, but using more than
one color-codes your tasks and gives you a better overview of your
day.

This module modifies the behavior of @file{planner.el}, adding global
task IDs so that tasks can be edited and updated. Planner IDs are of
the form @samp{@{@{Identifier:Number@}@}}.

@subheading Options

@defopt planner-id-add-task-id-flag
Non-nil means automatically add global task IDs to newly-created
tasks. If nil, use @command{planner-id-add-task-id} to add IDs to
existing tasks, or @command{planner-id-add-task-id-to-all} to add to
all tasks on the current page.
@end defopt

saved. If nil, use @command{planner-update-task} to update the linked
task. By default, linked tasks are automatically updated.
@end defopt

@defopt planner-id-tracking-file
File that contains ID tracking data. This file is automatically
overwritten.
@end defopt

@subheading Functions

The following interactive functions are defined in @file{planner-id.el}:

@defun planner-id-jump-to-linked-task &optional info

@defun planner-id-add-task
Add a task ID for the current task if it does not have one
yet. Update the linked task page, if any.
@end defun

@defun planner-id-update-tasks-on-page &optional force
Update all tasks on this page. Completed or cancelled tasks are not
updated. This can be added to @code{write-file-functions}. If
@var{force} is non-nil, completed and cancelled tasks are also
updated.
@end defun

@defun planner-id-add-task-id-to-all

@subsubsection Cyclic Tasks
@cindex @file{planner-cyclic.el}, using
@cindex tasks, cyclic
@cindex cyclic tasks
@cindex recurring tasks

If there are tasks that you have to do regularly, you can have Planner
schedule those tasks automatically.

Make sure that @file{planner-cyclic.el} is in your load path and add
this to your @file{.emacs} (or @file{_emacs}):

@example
(require 'planner-cyclic)
@end example

Create a diary file named @file{~/.diary.cyclic-tasks}
(or the value of @code{planner-cyclic-diary-file}). Here is an example:

@example
Tuesday #B0 _ Study Japanese
Friday #B0 _ Study Japanese (JapaneseStudies)
@end example

The first will be a plain task, the second will be linked.  The first
line will automatically create its task every Tuesday, while the
second will create it every Friday.

You can schedule tasks in a variety of ways. This module uses the same
syntax for specifying when tasks will be scheduled as the Emacs diary
uses for appointments and events. See @ref{Date Formats, the GNU Emacs
Manual, Date Formats,emacs, the GNU Emacs Manual}, and @ref{Sexp Diary
Entries, the GNU Emacs Lisp Reference Manual, Sexp Diary
Entries,elisp, the GNU Emacs Lisp Reference Manual}, for a full
description of the possibilities.

By default, planner-cyclic creates multiple tasks if you let tasks build
up (that is, the next Tuesday rolls around and you @emph{still} haven't
marked the task as done.) To turn off this behavior:

@example
(setq planner-cyclic-diary-nag nil)
@end example

@subheading Functions

@file{planner-cyclic-diary} includes the following interactive
functions:

@defun planner-cyclic-create-tasks-maybe
Maybe create cyclic tasks. This will only create tasks for future
dates or today.
@end defun

@node Task Detail, Deadlines, Cyclic Tasks, Creating New Tasks
@comment  node-name,  next,  previous,  up
@subsubsection Task Detail
@cindex tasks

You may find your planner pages getting very full, so that you want to
have one broad task entry be linked to a more specific list of
sub-tasks. Or, maybe you want to have a number of notes linked to a
particular task.
@cindex tasks, sub-
@cindex tasks, meta-
@cindex meta-tasks
@cindex sub-tasks

This can be done with targets.  You can have a task that is really a
meta-task:

@example
#A1  _ Do things in RevelleLog#13 @{@{Tasks:101@}@} (RevelleLog)
@end example

@samp{RevelleLog#13} could then be a list of sub-tasks in the form of
a note, or any kind of note.

Or, instead of pointing to a particular note on @samp{RevelleLog}, you
could have the whole page be tasks that you enter in manually, without
linking them to another page. You can just type them in like this:

@example
#A1  _ First specific thing to do
@end example

This way, the tasks will only appear on this specific project page,
and not on any daily page, so you only see them when you want to look
up all of the specific tasks associated with @samp{#A1  _ Do things in
RevelleLog @{@{Tasks:101@}@} (RevelleLog)}.

As you can see, the ability to manually enter tasks is one of
Planner's nicest features. It allows you to create tasks that are
not assigned to a specific date (by manually entering them on a
project page with no date) or to a specific project (by manually
entering them on a day page with no project). Yet as long as you enter
them using the syntax it understands, Planner will continue to
recognize them as tasks.

Another way to have a task not be connected to a particular date is to
do @kbd{C-c C-c} (@code{planner-copy-or-move-task}) and specify
@samp{nil} when asked for the date.

If you would like to see a list of all of your unfinished tasks, do
@kbd{M-x planner-list-unfinished-tasks}. This function only checks
day plan pages, not project pages.

@subsection Organizing Your Tasks
@cindex tasks, organizing
@cindex tasks, old

Okay, now that you've gotten the hang of creating tasks, you're probably
facing a really long list of things to do. How can you organize them so
that they don't overwhelm you? Planner gives you a number of strategies
for dealing with large numbers of tasks.

@enumerate
@item Arrange your tasks in the rough order you're going to do them.
@item Use #A, #B and #C task priorities to differentiate between
      high-priority, normal and low-priority tasks.
@item Schedule your tasks onto different days.
@item Group your tasks into plan pages.
@item Don't schedule all your tasks.
@end enumerate

@enumerate

@item @emph{Task order}

To remind yourself to do tasks in a certain order, simply edit the
lines so that they're in the order you want. You can use normal
editing commands like kill, yank and transpose-line to reorder the
tasks, or use @key{M-p} (@code{planner-raise-task}) and @key{M-n}
(@code{planner-lower-task}) to rearrange the tasks.

@item @emph{Task priorities}

By default, tasks are created with medium priority (@samp{#B}). You
can make a task high-priority (@samp{#A}) or low-priority (@samp{#C})
by manually editing the task and calling M-x planner-update-task to
update the linked page. Alternatively, you can use @key{C-M-p}
(@code{planner-raise-task-priority}) and @key{C-M-n}
(@code{planner-lower-task-priority}) to modify the task and update the
linked page.

You can edit the priority of a task using @kbd{M-x
planner-edit-task-priority}, or manually edit it and call @kbd{M-x
planner-update-task} to update tasks on the linked page.

@item @emph{Schedule your tasks on different days}

You don't have to do everything today. Is this a task you would rather
do tomorrow? Schedule it for then instead. You can specify @samp{+n}
or @samp{-n} whenever you are asked for a date, where @var{n} is the
number of days before or after the current file's date or today.
Don't over-procrastinate things, though!

@item @emph{Plan pages}

Plan pages let you group related tasks and notes together for easy
reference. For example, you could have a plan page for each major
project or goal in your life, like @samp{GoodHealth} or
@samp{FurtherStudies}.

Although plan pages start by grouping everything under a @samp{*
Tasks} header, you can organize your plan pages in different ways. For
example, you can separate groups of tasks with blank lines, and
Planner will sort tasks within each group.

@item @emph{Tasks without dates}

Plan pages also allow you to have undated tasks or tasks with no
particular deadlines. This keeps your daily task list small and
manageable while making it easier for you to find things to do if you
have free time. Make sure you check your plan pages regularly so that
you don't completely forget about them.

For automated scheduling of the next task on a plan page after you
complete a task, see the section in
@uref{http://sacha.free.net.ph/notebook/emacs/planner-config.el} named
``Schedule next undated task from same project''.

@subsubsection Associating Tasks with Multiple Projects
@cindex multiple projects
@cindex planner-multi.el, using

You can use @file{planner-multi.el} to associate a task with more than
one project. That way, you can easily keep GTD-style context lists as
well as project-related lists.

To use multiple projects, add the following to your @samp{~/.emacs}:

@example
(require 'planner-multi)
@end example

Under GNU Emacs, you can specify multiple projects by separating them
with a single space. For example, you can specify @kbd{planner doc}
when creating a task to associate the task with those two projects.

Under XEmacs, you can specify multiple projects by typing @kbd{RET}
after each entry and terminating the list with another @kbd{RET}. For
example, to specify @kbd{planner} and @kbd{doc}, you would type
@kbd{planner RET doc RET RET} at the prompt.

If you want to see an overview of all of your tasks as well as
project- or context-specific lists, you can set
@code{planner-multi-copy-tasks-to-page} to your overview page(s). For

@subsubsection Viewing tasks
@cindex tasks, viewing

Review the tasks scheduled for today by typing @kbd{M-x
planner-goto-today}.  If you created the task from the previous
section in this tutorial, you should see a line that looks like

@example
#A _ Learn how to change a task's status from Tasks (TaskPool)
@end example

If you have @code{planner-use-task-numbers} set to non-nil, you will see
something like the following instead.

@example
#A0 _ Learn how to change a task's status from Tasks (TaskPool)
@end example

From left to right, these are what the symbols mean:

@itemize
@item @samp{A} - Priority.  A (high)
@item
@samp{0} - Priority number.  It is calculated whenever you save the file
or call @command{planner-renumber-tasks}, provided that
@code{planner-use-task-numbers} is non-nil.  Tasks are numbered in
ascending order according to priorities.
@item @samp{_} - Status.  _ (unfinished)
@end itemize

If you click on @samp{Tasks} or press @key{RET} while your cursor is
in the link, Emacs will display the previous info page.

If you select @samp{TaskPool}, Emacs will display the @samp{TaskPool}
plan page.  Plan pages organize your tasks and notes about a project
in one file.

@subheading Functions

You can use @command{planner-seek-next-unfinished-task} to move to the
next unfinished task on the current page.

@defun planner-list-tasks-with-status status &optional pages
Display all tasks that match the STATUS regular expression on all day
pages.  The PAGES argument limits the pages to be checked in this
manner:

@itemize
@item @code{t}: check all pages
@item regexp: search all pages whose filenames match the regexp
@item list of page names: limit to those pages
@item alist of page/filenames: limit to those pages
@end itemize

Called interactively, this function will search day pages by
default. You can specify the start and end dates or leave them as
nil to search all days. Calling this function with an interactive
prefix will prompt for a regular expression to limit pages.
Specify @samp{.} or leave this blank to include all pages.

This function could take a long time.

@node Modifying Tasks, Carrying Over Unfinished Tasks, Viewing Tasks, Organizing Your Tasks
@comment  node-name,  next,  previous,  up
@subsubsection Modifying Tasks
@cindex tasks, modifying
@cindex tasks, editing

To select a task, move your cursor to the line containing the task.

Change a task's priority (@samp{A}, @samp{B} or @samp{C}) by editing
the line. @samp{#A} tasks are important. @samp{#B} are medium
priority. @samp{#C} are low priority. Whenever you save the file or
call @kbd{M-x planner-fix-tasks}, tasks are sorted and numbered
according to priority and status.

Change a task's status by calling one of the following functions:

@itemize
@item planner-task-in-progress @samp{o} (@kbd{C-c C-z})
@item planner-task-done @samp{X} (@kbd{C-c C-x})
@item planner-task-cancelled @samp{C} (@kbd{C-c C-S-x})
@item planner-task-delegated @samp{D}
@item planner-task-pending @samp{P}
@item planner-task-open @samp{_}
@end itemize

After changing the status using a function, look at the
@samp{TaskPool} plan page.  The task is also updated on the linked
page.  If you changed the task status manually by replacing the status
with another character, you will need to call
@command{planner-update-task} to update the linked page.

To reschedule a task, call @command{planner-copy-or-move-task} (@kbd{C-c
C-c}) and choose a new date.  You can mark a region and type @kbd{M-x
planner-copy-or-move-region} to reschedule all the contained tasks to a
different date.  Enter @samp{nil} for the date if you don't want the
task or group of tasks to appear on any date page at all anymore. This
is a good way to ``de-schedule'' a task for the time being, but still
keep it linked to a plan page for possible future scheduling.

To change the plan page associated with a task, call
@command{planner-replan-task}.  Enter @samp{nil} for the plan page if
you don't want the task to appear on any plan page anymore. If you
precede the command with a prefix argument, the text of the original
plan page will appear in the prompt for easy editing.

Since the same task may exist on two or more pages, such as a date page
and a plan page, it is dangerous to edit the description of the task by
hand. You should not do it unless you want to make the exact same
changes on all its linked pages.

Instead of doing this by hand, you should use
@command{planner-edit-task-description}. This will prompt you for the
changes to the task description and then update all the other pages to
which the task is linked.  Or, you can just use
@command{planner-delete-task} to remove the task from both pages, and
then create it again with the new desired description.

To remind yourself to do tasks in a certain order, simply edit the
lines so that they're in the order you want.
@command{planner-raise-task} and @command{planner-lower-task} update
the priorities on linked pages automatically. You can organize tasks
into groups by putting a blank line between groups of tasks.
Planner will maintain the groupings and only sort the tasks within
that group.

@subheading Functions

@defun planner-replan-task page-name
Change or assign the plan page for the current task.  @var{page-name}
is the new plan page for the task. Use
@code{planner-copy-or-move-task} if you want to change the date. With a
prefix, provide the current link text for editing.
@end defun

@defun planner-raise-task-priority
Change a low-priority task to a medium-priority task and a
medium-priority task to a high-priority task (C to B to A).
@end defun

@defun planner-lower-task-priority
Change a high-priority task to a medium-priority task and a
medium-priority task to a low-priority task (A to B to C).
@end defun

@defun planner-raise-task arg
Move a task up @var{arg} steps.  By default, @var{arg} is 1.
@end defun

@defun planner-lower-task  arg
Move a task down @var{arg} steps.  By default, @var{arg} is 1.
@end defun

@defun planner-edit-task-description description
Change the description of the current task, updating the linked page
if any.
@end defun

@defun planner-delete-task
Delete this task from the current page and the linked page.
@end defun

@defun planner-update-task
Update the current task's priority and status on the linked page.
Tasks are considered the same if they have the same description.
This function allows you to force a task to be recreated if it
disappeared from the associated page.
  
Note that the text of the task must not change. If you want to be able
to update the task description, see @code{planner-edit-task-description}
or @file{planner-id.el}.

@subsubsection Carrying Over Unfinished Tasks
@cindex tasks, carrying over

Sometimes you won't be able to cross off all the tasks on your list.
Planner makes it easy for you to keep track of things you still have
to do by automatically rescheduling unfinished tasks from the past few
days. By default, the @command{plan} command searches for unfinished
tasks from the last three days and reschedules them onto today. If you
open Planner every day, this should cover weekends easily.

It's a good idea to start Planner whenever you start Emacs. That way,
Planner can help remind you about today's tasks, appointments, and other
things. To automatically start Planner whenever you start up Emacs, add
the following code to the end of your @file{~/.emacs}:

@example
(plan)
@end example

Now, every time you start Emacs (which should be more or less once a
day), you'll see today's page. If you don't finish all the tasks today,
you'll see them again tomorrow.

It's a good idea to start Planner every time you start Emacs so that
you get reminded about your task list. If you prefer to start Planner
manually, remember to call @kbd{M-x plan} every so often to make sure
that you don't forget any unfinished tasks. Safe in the knowledge that
Planner tasks won't slip through the cracks (unlike little slips of
paper that will invariably get mislaid), you can then get on with the
rest of your life.

If your increased productivity with Planner leads to a well-deserved
two-week vacation, then you'll need to tell Planner to search more days
for unfinished tasks. By using @kbd{M-x plan}, you can automatically
bring forward tasks over a given number of days or even scan all the
days since time immemorial. @kbd{C-u 15 M-x plan} reschedules all
unfinished tasks from the last 15 days. @kbd{C-u -1 M-x plan} checks all
of your past day pages for unfinished tasks.

Like everything else in Planner, you can adapt @kbd{M-x plan} to your
particular way of life. For example, if you find yourself starting up
Emacs and Planner every day--including weekends--because it's just so
much fun, you can set the @code{planner-carry-tasks-forward} to 1.
This can make your Emacs startup marginally faster. On the other hand,
if you normally start Emacs once a week, you can set it to 7 or 8. If
you're worried about tasks dropping off your radar, you can set it to
0. You can set the value of @var{planner-carry-tasks-forward} either
with @key{M-x customize-variable RET planner-carry-tasks-forward RET},
or by putting @code{(setq planner-carry-tasks-forward 3)} (replacing
@code{3} with the value appropriate for what you want) in your
@file{~/.emacs} file.

On the other hand, you might prefer to reschedule tasks yourself. If
you set @code{planner-carry-tasks-forward} to @code{nil}, then
@command{M-x plan} and @code{(plan)} will bring you to the most recent
page with unfinished tasks if there is no page for today. You can then
use @command{planner-copy-or-move-task} and
@command{planner-copy-or-move-region} to reschedule tasks. This is
probably more hassle than it's worth, though, so let Planner take care
of this for you.

@subheading Options

@defopt planner-carry-tasks-forward
If non-nil, carry unfinished tasks forward automatically.
If a positive integer, scan that number of days in the past.
If 0, scan all days for unfinished tasks.
If t, scan one day in the past (old behavior).
If nil, do not carry unfinished tasks forward.
@end defopt

If @var{force-days} is @code{0} or @code{t}, scan all days.
If @var{force-days} is @code{nil}, use the value of
@code{planner-carry-tasks-forward} instead, except t means scan only
yesterday

@end defun

@defun planner-copy-or-move-task date force
Reschedule the task for @var{date}. If @var{force} is non-nil, the

plan page in order to get better completion.
@end defun

@defun planner-copy-or-move-region beg end date muffle-errors

@code{planner-copy-or-move-region} will copy or move all tasks from
the line containing @var{beg} to the line just before @var{end}. If
@var{muffle-errors} is non-nil, no errors will be reported.

@node Task Numbering, Task Ranks, Carrying Over Unfinished Tasks, Organizing Your Tasks
@comment  node-name,  next,  previous,  up
@subsubsection Task Numbering

By default, tasks are numbered according to their position on the
page.  Task numbers allow you to refer to tasks using Muse links.
For example, the @samp{#A1} task in @file{2004.08.16} can be referred to
as @samp{2004.08.16#A1}.

Note that task numbers change every time you re-sort and re-number tasks
with @code{planner-fix-tasks}.  As a result, they are only reliable for
references to past tasks.

If you find yourself not using this functionality, you can turn off task
numbers by using the following option.

@subheading Options

@defopt planner-use-task-numbers
Non-nil means use task numbers when creating tasks.  This allows you
to refer to past tasks if your tasks are numbered appropriately.
If you set this to nil, you can save space in your plan files.

@comment  node-name,  next,  previous,  up
@subsubsection Task Ranks
@cindex ranking tasks
@cindex tasks, ranking
@cindex @file{planner-rank.el}, using

@file{planner-rank.el} models Franklin Covey's Urgency and Importance
principle. When you think about a task, there are two aspects in
consideration: Urgency and Importance. You may want to do the most
urgent things first, like answering an email, or you may want to do
the most important things first, like reading this manual. Or much
better, balance Urgency and Importance and decide what to do.

@file{planner-rank.el} can help you balance.

Urgency and Importance are both measured by scores from 0-9. The
higher the score, the more you want to do it first. 9 stands for ``I
should have done this'' and 0 stands for ``I can forget this''.

If you are using the planner @ref{Deadlines} feature, the Urgency
score is automatically calculated from how many days are left to meet
the deadline. By default, it will score 9 if the task is overdue and 0
if the deadline is years away. Please refer to the docstring of
@code{planner-rank-deadline-urgency-map-list} for detail.

The task rank is calculated from Urgency and Importance scores. As
different people balance urgency and importance differently, a number
of @code{planner-rank-calculate-rank-*} functions are provided. The
algorithms vary from a simple average to something like a weighted
root mean square deviation.

The aggressive versions of these functions
(@code{planner-rank-calculate-rank-*-aggressive}) will make sure if
one of Urgency and Importance is high, the resulting rank will be high
as well. @code{planner-rank-calculate-rank-weighted-*} functions weigh
the Urgency and Important scores depending on
@code{planner-rank-importance-vs-urgency-factor}.

Call @code{planner-rank-test-algorithm} on each of the functions and
check the result tables to see which one you like most, and set it to
@code{planner-rank-rank-calculate-function}. Alternatively, accept the
defaults and tweak them when you get a better feel for ranking.

Once the Rank is calculated, the @ref{Task Priorities} will be
automatically reset. If the Rank is greater than or equal to
@code{planner-rank-priority-A-valve}, the task priority will be
@samp{A}, if the Rank is between @code{planner-rank-priority-A-valve}
and @code{planner-rank-priority-B-valve}, the priority will be @samp{B},
else it will be @samp{C}.

After setting the task importance and deadline, you can leave it as
is. As the deadline approaches, the task priority will automatically
be raised and the task re-colored to catch your eyes.

If you are using @code{planner-sort-tasks} (see @pxref{Making Files
Pretty}), you can set @code{planner-sort-tasks-key-function} to one of
@code{planner-sort-tasks-by-rank},
@code{planner-sort-tasks-by-importance}, and
@code{planner-sort-tasks-by-urgency}.

@subsubsection Grouping Tasks with planner-trunk.el
@cindex grouping tasks
@cindex tasks, grouping
@cindex @file{planner-trunk.el}, using

@file{planner-trunk.el} helps you automatically group tasks according
to a set of rules. It sorts and splits your tasks, adding a blank line
between groups of tasks. For example, if today's page looks like this:

@example
* Tasks

#B   _ Buy milk (GroceryShopping)
#B   _ Learn how to use planner-trunk (PlannerMode)
#B   _ Buy a notebook (Bookstore)
#B   _ Buy cereal (GroceryShopping)
#B   _ Set up my own planner-trunk rules (PlannerMode)
#B   _ Customize my stylesheet (MuseMode)
#B   _ Go for a health checkup (BetterHealth)
@end example

@noindent
then you might want to group the tasks into: planner and muse,
shopping list, and other items. If you set up the appropriate rules by
customizing @code{planner-trunk-rule-list}, @file{planner-trunk.el}
can automatically rewrite that section line this:

@example
* Tasks

#B   _ Learn how to use planner-trunk (PlannerMode)
#B   _ Set up my own planner-trunk rules (PlannerMode)
#B   _ Customize my stylesheet (MuseMode)

#B   _ Buy milk (GroceryShopping)
#B   _ Buy a notebook (BookstoreShopping)
#B   _ Buy cereal (GroceryShopping)

#B   _ Go for a health checkup
@end example

@noindent
In this case, you would set @code{planner-trunk-rule-list}
to @code{(("." nil ("PlannerMode\\|MuseMode" "Shopping")))}.

You can load @file{planner-trunk} with @kbd{M-x load-library RET
planner-trunk RET} or add @code{(require 'planner-trunk)}. If you're
not yet comfortable with Emacs Lisp, you can use @kbd{M-x
customize-variable RET planner-trunk-rule-list RET} to edit this rule
using an easy-to-use interface.

WARNING: Do not keep non-task information in the Tasks section.
planner-trunk will delete @strong{all} non-task lines from the Tasks
section of your plan page in the process of grouping the tasks.

After you set up @code{planner-trunk-rule-list}, use @command{M-x
planner-trunk-tasks} to try out your rules until you're satistfied.

If you want to do this automatically, you can use @code{(add-hook
'planner-mode-hook 'planner-trunk-tasks)} to trigger it automatically
whenever you open a Planner page.

When assessing where you stand in relation to the tasks you have set
out for yourself, you might want a way to survey those tasks in groups
divided by time periods, like by the week or by the month. You could
create all of these overview pages by hand, but if you like to have
this kind of overview frequently, you might find manually creating
such pages to be tedious and time consuming.

@file{planner-zoom} is an optional module designed to make it easy to
view your task information grouped by year, quarter, month, week or
day.

To install this module, just load it in your @file{.emacs} (or
@file{_emacs}):

@example
(require 'planner-zoom)
@end example

This module will recognize planner pages named according to the
following scheme:

@table @asis

@item year view
@file{2006.Year}

@item quarter view
@file{2006.Quarter2}

@item month view
@file{2006.January}

@item week view
@file{2006.January.Week3}

@item day view
@file{2006.01.02}

@end table

@subheading Keybindings

This module also adds key bindings that you can use when looking at a
Planner page to easily jump between the different time-period views.

@table @kbd

@item S-up
Move to the view corresponding to the time period one step larger than
the current one. For example, it moves from the weekly view to the
monthly view. It calls @code{planner-zoom-iup}.

@item S-down 
Move to the view corresponding to the time period one step smaller
than the current one. For example, it moves from the weekly view to
the daily view. It calls @code{planner-zoom-idown}.

@item S-left
Stay in the same time-period view as the current one, but move one
interval earlier. For example, it moves from @file{2006.January.Week3}
to @file{2006.January.Week2}. It calls @code{planner-zoom-iprev}.

@item S-right
Stay in the same time-period view as the current one, but move one
interval later. For example, it moves from @file{2006.January.Week3}
to @file{2006.January.Week4}. It calls @code{planner-zoom-inext}.

@end table

@subheading Example usage

Look at the page named @file{2006.January} and then hit @kbd{S-down}
which will show @file{2006.January.Week1}. Then hit @kbd{S-left} and
@kbd{S-right} to look at @file{2006.January.Week2},
@file{2006.January.Week3}, etc.

@subheading Advanced tips and options

You can use any prefix argument with @code{planner-zoom-iup} and
@code{planner-zoom-idown} to have the new view display in a window
other than the current one. This also works with a nonnumeric prefix
argument and @code{planner-zoom-inext} or @code{planner-zoom-iprev}.
For these two functions, a numeric prefix will specify the number of
intervals to move.

If you don't like the default patterns for naming the time-period view
pages, you can change them by customizing @code{planner-zoom-regexps}.

Some people believe weeks start with Sunday, and some believe they
start with Monday. To accommodate both of these colliding worldviews,
@code{planner-zoom-first-day-of-week} can be customized. Its default
value is @samp{1}, which is Monday. If you would prefer Sunday, change
it to @samp{0}. The month to which a week belongs is the month in
which the first day of the week falls.

@subheading Command reference

@defun planner-zoom-iup name other-window
Move to the next higher level in the hierarchy. With a prefix
argument, show the desired page in the other window.
@end defun

@defun planner-zoom-idown name other-window
Move to the next lower level in the hierarchy. If the current date is
within the higher-level time range, zoom to the lower level time range
that also contains today. Otherwise, just go to the first lower-level
time range. With a prefix argument, show the desired page in the other
window.
@end defun

@defun panner-zoom-inext name num other-window
Move to the next time range at the same level in the hierarchy. With a
numeric prefix argument, move by that number of time ranges. With a
non-numeric prefix argument, show the desired page in the other window.
@end defun

@defun planner-zoom-iprev name num other-window
Move to the previous time range at the same level in the hierarchy.
With a numeric prefix argument, move by that number of time ranges.
With a non-numeric prefix argument, show the desired page in the other
window.
@end defun

@node More about Notes, Making Files Pretty, More about Tasks, More about Planner
@section More about Notes
@cindex notes, more about
You can put anything in this section. Notes added by
@file{remember-planner.el} look like this:

@example
.#1 Headline
Body
@end example

and are outlined at the @code{H3} level. If you want to take notes
conveniently, check out @file{remember-planner.el}.

Planner by default organizes the notes on a planner page so that
the most recent note is first. Each note is numbered, with the oldest
note labeled @samp{.#1}. If you would like to reverse this behavior,
look at @kbd{C-h v planner-reverse-chronological-notes}.

Notes are associated with day pages, but can also be associated with
plan pages when they are created.  A linked note looks like this:

@example
.#1 Headline (LinkedNote#1)
Text
@end example

You can jump to the linked note with
@command{planner-jump-to-linked-note}.

Deleting a note can be dangerous, as the notes are automatically
numbered.  Removing a note could break links in other pages.

@subheading Functions

@defun planner-create-note page
Create a note to be remembered in @var{page} (today if @var{page} is
nil).  If @code{planner-reverse-chronological-notes} is non-nil, create
the note at the beginning of the notes section; otherwise, add it to
the end.  Position point after the anchor.

@cindex notes, displaying

The format of the notes in Planner works well with Allout mode, which
provides helpful commands for navigating and formatting outlines. You
can, for example, hide the bodies of all the notes on a page so you can
see just their headlines. You can also jump easily from headline to
headline, skipping over the bodies in between.

The commands for using Allout mode vary depending on which Emacs version
you are using. In either case, type @kbd{M-x load-library @key{RET}
allout @key{RET}} to start. If you are using CVS Emacs, type @kbd{M-x
allout-mode @key{RET}}. If you are using an earlier version of Emacs,
type @kbd{M-x outline-mode @key{RET}}.

The exact commands then available to you differ depending on your Emacs
version, but you can view the commands and their keybindings by typing
@kbd{C-h m}. In CVS Emacs, they will start with @command{allout-}, while
in previous versions, they will start with @command{outline-}.

@samp{<past-notes>} is replaced by an index of note headlines.
If @var{start} is specified, it lists notes starting from that date.
If @var{directory} is specified, you can index notes in another
planner directory.

Make sure that @file{planner-notes-index.el} is in your load path and
add this to your @file{.emacs} (or @file{_emacs}):

@example
(require 'planner-notes-index)
@end example

Then you can use tags of the form:

@example
<planner-notes-index page="2004.03.02">
<planner-notes-index from="2004.03.01" to="2004.03.31">
<planner-notes-index limit="10">
<planner-notes-index page="PlanPage">
<planner-notes-index-month-table month="2004.03" limit="5">
<planner-notes-index-month-table month="2004.03">
@end example

You can also use the following interactive functions:

@code{planner-notes-index}
@code{planner-notes-index-days}
@code{planner-notes-index-weeks}
@code{planner-notes-index-months}
@code{planner-notes-index-years}    (wow!)

These work based on the current date (date of current buffer, or today).

If a single page is specified, this page is scanned for headlines
of the form:

@example
 .#1 Headline
@end example

The results are presented as a bulleted list.

If @var{from} and @var{to} are specified, all date pages between them
(inclusive) are scanned. If @var{from} is omitted, it is assumed to be
the earliest entry.  If @var{to} is omitted, it is assumed to be the
latest entry.

If @var{recent} is specified, the list includes only that many recent
headlines.  and the results are presented as a bulleted list.

To customize presentation, you can write a function that generates
the appropriate @code{<planner-notes-index>} tags. You can also use
@code{planner-extract-note-headlines} in your own functions.

@subheading Functions

The following interactive functions are defined in
@file{planner-notes-index.el}:

@defun planner-notes-index &optional from to limit

@node Making Files Pretty, Annotations, More about Notes, More about Planner
@section Making Files Pretty

By default, planner does a little bit of fancy reformatting when you
save a file. Tasks are sorted by priority (ABC) and status (_oP>XC) on
day pages. On plan pages, tasks are sorted by priority (ABC), status
(XC), and date. Undated tasks are sorted after dated tasks.

@subheading Options

@defopt planner-sort-tasks-key-function
Control task sorting. Some options include
@code{planner-sort-tasks-default-key},
@code{planner-sort-tasks-basic}, @code{planner-sort-tasks-by-date}, and
@code{planner-sort-tasks-by-link}.
@end defopt

@defopt planner-sort-undated-tasks-equivalent
This option controls the behavior of task sorting on plan pages.  By
default, the value @samp{9999.99.99} causes dated tasks to be listed
before undated tasks.  To sort undated tasks before dated tasks,
set this to a blank string.
@end defopt

@defopt planner-sort-tasks-automatically
Non-nil means sort tasks whenever a planner file is saved.  On day
pages, tasks are sorted by status.  On plan pages, they are sorted by
status and date.  Sorting can take a while.
@end defopt

@defopt planner-renumber-tasks-automatically
Non-nil means renumber tasks from 1 to N whenever a planner file is
saved. This allows you to refer to tasks in previous day pages using
anchors like @samp{2003.08.12#A1}. If you use this function, make sure
@code{planner-use-task-numbers} is non-nil so that new tasks are created
with task numbers.
@end defopt

@defopt planner-align-tasks-automatically
Non-nil means align tasks whenever a planner file is saved.  This
causes the status to line up in a neat column if you have less than
100 tasks.
@end defopt

@defopt planner-renumber-notes-automatically
Non-nil means renumber the notes. If most of your notes are only on
one page, you might like seeing the notes renumbered if you delete a
note in the middle. However, if you use a lot of cross-referencing,
note renumbering will break those links.
@end defopt

@subheading Functions

@defun planner-sort-tasks
Sort tasks according to planner-sort-tasks-key-function. By default,
sort tasks according to priority and position on day pages, and
according to status, priority, date, and position on plan pages.
@end defun

@defun planner-renumber-tasks
Update task numbering.
@end defun

@defun planner-align-tasks
Align tasks neatly. You can add this to @code{write-file-functions} to
have the tasks automatically lined up whenever you save.  For best
results, ensure @code{planner-align-tasks} is run after
@code{planner-renumber-tasks}.

@node Annotations, Interactive Lisp, Making Files Pretty, More about Planner
@comment  node-name,  next,  previous,  up
@section Annotations

The context included when you create a task and the context included
when you create a note are gained the same way. It sounds like black
magic, but it turns out not to be.

All that happens is, Planner has a list of functions,
@code{planner-annotation-functions}. When you create a task from a
buffer, or remember a note from a buffer, Planner goes through
this list from top to bottom. The first one that returns true is the
one it uses.

For example, if you're in Wanderlust, and you hit the key you've bound
to @code{planner-create-task-from-buffer}, it looks at this list and
does something like this.  Is it an ERC buffer? No. Is it a BBDB
buffer? No. Are we in w3m? No. Are we in Wanderlust? Yes. So this
function succeeds. It stops searching and runs the annotation function
for Wanderlust, which in this case finds out who the message is from
and what the message ID of the message is. It then takes those and
constructs a link back to that message, with a link title something
like @samp{Email from Joe Blogs}.

So, you've read the email from Joe Blogs. He's asked you to do
something and you've hit your key to add that task to your list of
things to do. So what you end up with is a description of the task,
and a link back to what made you create the task in the first place.

The same happens with remembering notes, except that it ends up in the
@samp{* Notes} section of your page instead.

By default, @file{planner.el} can annotate tasks and notes based on
the current filename.

@subheading Options

To change the behavior of annotations, customize the following options:

@defopt planner-annotation-functions
A list of functions tried in order by
@command{planner-create-task-from-buffer} and other functions that
pick up context.  The first non-nil value returned is used as the
annotation.  To cause an item to @strong{not} be annotated, return the
empty string @samp{""}.
@end defopt

@defopt planner-annotation-strip-directory
File links are usually generated with the full path to the file so
that you can easily tell apart files with the same base name.  If
@code{planner-annotation-strip-directory} is non-nil, though, only the
base name of the file will be displayed.  For example, a link to
@samp{/foo/bar/baz} will be displayed as @samp{baz} and hyperlinked to
the file.
@end defopt

@defopt planner-annotation-use-relative-file
If t, always use relative filenames.
@code{planner-annotation-use-relative-file} can also be a function that
takes the filename and returns non-nil if the link should be relative.
Filenames are resolved relative to the first directory of your Planner
project in @code{muse-project-alist}.  That is, the created link will be
of the form @samp{../../somefile} instead of
@samp{/absolute/path/to/file}.  This can be helpful if you publish your
planner files to the Net and your directory structure ensures that
relative links resolve the same from your Plan pages and their
respective publishing directory.

First, you need @file{planner-lisp.el}. Put this in your @file{.emacs}
(or @file{_emacs}):

@example
(require 'planner-lisp)
@end example

Then, add a link to the Lisp function to your page, like:

@example

[[lisp:/plan][Plan]]

@end example

This will be rendered as @samp{Plan}. Selecting the link will run the
@code{plan} function interactively.

You can also execute other Lisp expressions. For example:

@example
[[lisp:/(planner-goto (planner-expand-name "+7"))][Next week]]
@end example

@file{planner-lisp.el} does not provide any interactive functions or
keybindings.

@node Publishing, Experimental Functions, Interactive Lisp, More about Planner
@section Publishing

You can publish your planner files to HTML and put them on a normal
web server--no special server support required. This gives you an easy
way to keep other people up to date on your tasks, keep a web log, or
simply organize information.

Publish your planner wiki with @kbd{C-c C-p}
(@code{muse-project-publish}). You can publish individual files with
@kbd{C-c C-t} (@code{muse-publish-this-file}). To automatically publish
files when you save them, add the following code to your
@file{~/.emacs}:

@example
(eval-after-load "muse-mode"
  (add-hook 'after-save-hook
            #'(lambda ()
                (when (planner-derived-mode-p 'muse-mode)
                  (muse-project-publish nil)))
            nil t))
@end example

Published files are stored in the path specified by
@code{muse-project-alist} for your Planner project.  Just copy the
contents of this directory to your webserver, and you're all set! Of
course, publishing is completely optional.

@cindex calendar, publishing
@cindex @file{planner-calendar.el}, using

To publish calendars in your day pages, it is necessary to do two steps.

@itemize
@item Add @code{(require 'planner-calendar)} to your configuration.
@item Add a @samp{<calendar>} tag to either your header, footer, or
@var{planner-day-page-template}, depending on where you want it to
appear.
@end itemize

To display a calendar based on a different day (given here as DAYPAGE),
use @code{<calendar page="DAYPAGE">}.

To get arrows to previous and next months to show up, use
@code{<calendar arrows="t">}.  The text in
@var{planner-calendar-prev-month-button} and
@var{planner-calendar-next-month-button} will be used for the arrows to
the previous and next months, respectively.

By default, Muse will not display the arrows properly, due to
limitations in the special-escaping algorithm.  To work around this,
remove the @samp{&} rule from @var{muse-xml-markup-specials}, or from
@var{muse-html-markup-specials} if you are using the 3.02.6 version of
Muse.

It is also possible to create a symlink from the current day page to the
page name specified by @var{planner-calendar-today-page-name}.  To
accomplish this, add the following to your configuration.

@example

@subsection Authz Access Restriction
@cindex @file{planner-authz.el}, using
@cindex Mason, restricting portions with
@cindex access, restricting

@file{planner-authz.el} was written by Andrew J. Korty in order to
allow the easy restriction of portions of published pages.  It uses
the HTML::Mason module available on CPAN
(@url{http://www.cpan.org}).  Setting up HTML::Mason is
outside the scope of this document.  Make sure that it works before
trying out @file{planner-authz.el}.

@file{planner-authz.el} modifies the behavior of
@command{muse-project-publish} so that published pages follow access
modifiers.

This library lets you publish your planner pages while controlling
access to certain portions of them to users you specify.  When you
load this library, you gain access to two additional markup directives
to use in your planner pages.  The @samp{<authz>} tag lets you
restrict access to arbitrary content as follows:

@example
Here is a sentence everyone should see.  This sentence also
contains no sensitive data whatsoever.  <authz users="ajk">This
sentence, however, talks about my predilection for that French
vanilla instant coffee that comes in the little tin, and I'm
embarrassed for anyone else to know about that.</authz> And
here's some more perfectly innocuous content.
@end example

You can use @samp{<authz>} tags to mark up entire paragraphs, tasks,
notes, and anything else.  The tags are replaced with Mason code in
the published pages.

The @samp{#authz} directive restricts access to an entire page.  A Mason
call is added to this page to generate a 403 error when someone not
listed tries to access it.  Any notes or tasks on a
@samp{#authz}-protected page are also wrapped in Mason code on linked
pages. To add a @samp{#authz} directive to a Muse page, place
@samp{#authz} followed by a space-delimited list of users on one
line. For example:

@example
#authz ajk sacha
@end example

@subheading Options

@defopt planner-authz-project-default
Default access list for project pages (not day pages).  If a given
project page doesn't contain a @samp{#authz} tag, it will receive the

@file{planner-rss.el} allows you to publish your notes in the RSS 2.0
XML format for blog syndication. You will also want to customize the
following variables:

To manually add the current note to all the matching RSS feeds, invoke
@command{planner-rss-add-note}. You can specify a filename with the
universal prefix, like this: @kbd{C-u M-x planner-rss-add-note}.

If you use the @file{remember-planner.el} module to create notes, you
can automatically publish new notes to RSS feeds by adding the
following code to your @file{.emacs} (or @file{_emacs}).

@example
(add-to-list 'remember-planner-append-hook 'planner-rss-add-note t)

@subsubsection Publishing with planner-rdf

Planner-rdf is now included in the normal Planner publishing process.
Pressing @key{C-p} will create a .owl and a .rdf file for every planner
file. Additionally it creates an index, @file{index.rdf}.

By default all generated files will be stored in the normal Planner
publishing directory, where the HTML files end up. If you would ike to
change that, set the variable @code{planner-rdf-directory} to the desired
location.

The generated files:

@itemize
@item
@file{index.rdf} - a collection with pointers to the
@file{<plan-page>.rdf} files.
@item
@file{<plan-page>.rdf} - contains Dublin Core metadata about the files
related to the current Planner page. Currently it contains metadata
about the source file, the Emacs plan page, the generated HTML page, and
the generated OWL file.
@item
@file{<plan-page>.owl} - contains task and note data from the Planner
file. Task information is stored completely. For notes, the note
headline is stored.
@end itemize

@node planner-rdf Tags, planner-rdf Usage Examples, Publishing with planner-rdf, RDF Publication
@subsubsection planner-rdf Tags

Besides the factual information, e.g. the task status or description,
planner-rdf extracts links (in the format @samp{[[...][...]]} or
@samp{[[...]]}) and tags (@samp{@{@{...:...}@}@}) from tasks and notes
(including the notes text). Links and tags provide context for the plan
elements and so are stored and linked with the containing elements.

Links point to locations that can be used to enrich the information in
the Planner pages (e.g, by retrieving data from them and adding it),
tags -- like the one for the task ids @samp{@{@{Tasks:198@}@}} -- can be
used to express abstract qualities. Some examples:

@itemize
@item
an @samp{@{@{audience:myteam@}@}} tag, can be used to restrict
publishing of items to a certain user group;
@item a @samp{@{@{lang:de@}@}} tag, signifying the language of the text;
@item
a @samp{@{@{location:Hamburg@}@}} tag, can be used to make geographic
reference to an entity that is not stored in your address book, bbdb.
@end itemize

What tags to use is up to the user. Planner-rdf makes no assumptions
about them, it just extracts and stores them. Only the applications
using the data know what to do with them.

@node planner-rdf Usage Examples,  , planner-rdf Tags, RDF Publication
@subsubsection Usage Examples

Report generation with OpenOffice

The Perl file @file{this-week.pl}
(@url{http://www.rainervolz.de/planner-rdf/this-week.pl}) creates a
simple report for the current week. The script extracts task and note
information from the generated OWL files and inserts it into a simple
OpenOffice Writer document. Nothing fancy, just a proof of concept, to
show how planner-rdf can be used to integrate Planner Mode with other
applications.

Besides Perl and OpenOffice you'll need the Redland RDF Application
Framework (@url{http://www.redland.opensource.ac.uk/}). It is used to
process the RDF data. Redland is small, but powerful, and available
for many platforms and languages.

As an example the application loads the RDF data each time it is run.
In the real world you probably would use Redland to store the Planner
data in a database, to save the loading step each time you access the
data.

Importing Planner data into Protege

Protege is a popular ontology editor and knowledge management
application. A simple way to import data into it, is to provide a OWL
file that contains the data as well as the schema. To do this:

@itemize
@item
Use @file{planner2protege.pl}
(@url{http://www.rainervolz.de/planner-rdf/planner2protege.pl}) to
combine all OWL files into a single one.
@item
Use CWM (@url{http://www.w3.org/2000/10/swap/doc/cwm.html}) to combine
schema and data, with @code{python cmw --rdf planner-rdf.owl
planner-data.owl --think --rdf >planner2.owl}
@end itemize

Not the most straightforward process, but it works. The resulting file,
here planner2.owl, can then be loaded into Protege.

@subsection Diary
@cindex diary, using Planner with
@cindex @file{planner-diary.el}, using

If you use Emacs's diary feature, Planner-Diary could be helpful for
you. It puts all diary entries for the current day in the @samp{*
Diary} section of your day plan page. This section is updated every
time you display the file in Emacs. By default the diary section of
past pages is not updated; it's pretty unlikely that you want to add
new diary entries for the past. (@pxref{Diary, , , Emacs, GNU Emacs
Manual})

If you want to use @file{planner-diary.el}, make sure the file is in
your load path and add this to your @file{.emacs} (or @file{_emacs}):

@example
(require 'planner-diary)
@end example

@file{planner-diary.el} needs @command{fancy-diary-display}.  To use
@command{fancy-diary-display}, add this to your @file{.emacs} (or
@file{_emacs}):

@example
(add-hook 'diary-display-hook 'fancy-diary-display)
@end example

You can use Planner-Diary in two different ways:

@enumerate

@item
If you want the saved files to contain your entries and not just a line
of Lisp, add the following lines to your @file{.emacs} (or @file{_emacs}):

@example
(setq planner-diary-use-diary t)
(planner-diary-insinuate)
@end example

You should also customize or set @code{planner-day-page-template} to
include a @samp{* Diary}:

@example
(setq planner-day-page-template
 "* Tasks\n\n\n* Schedule\n\n\n* Diary\n\n\n* Notes")
@end example

@item
(GNU EMACS ONLY) You can put the following line of Lisp code in your
day plan pages to display your diary entries:

@example
<lisp>(planner-diary-entries-here)</lisp>
@end example

You can do this automatically for all day plan pages:

@smallexample
(setq planner-day-page-template
  "* Tasks\n\n\n* Diary\n\n<lisp>(planner-diary-entries-here)</lisp>
\n* Notes")
@end smallexample

When you open a day plan page outside Emacs, you will see the line of
Lisp code and not your diary entries.

@end enumerate

If you want to see your diary entries for more than just one day, set
@code{planner-diary-number-of-days} accordingly.  This works for either
of the two approaches.

@kbd{C-c C-e} updates the diary sections.  @kbd{C-u C-c C-e} forces an
update---it inserts the diary section for the day, even if the day is in
the past or if there is no @samp{Diary} section in the buffer.

If you want to use the Cal-Desk package, simply follow the instructions
in @file{cal-desk.el}.  If you get the Cal-Desk layout from the Calendar
buffer, you get it in the day plan buffer, too.

If you use Planner-Diary, you might consider using the Calendar support
of Planner. (@pxref{Calendar/Diary, , , Emacs, GNU Emacs Manual}) To get
Calendar integration, add this to your @file{.emacs} (or @file{_emacs}):

@example
(planner-insinuate-calendar)
@end example

If @code{planner-diary-create-section-flag} is non-nil, sections are
always inserted if necessary.

@subheading Options

@defopt planner-diary-create-section-flag
Non-nil means create the requested diary sections if they do not
exist. By default, planner-diary tries to create the section. If you
want more control over your pages, you can set this to nil. Trying to
write a diary section to a page that does not have it yet will then
result in an error.
@end defopt

By default, planner-diary lists only the appointments you have on that
day. If you want the date headers included even when showing the diary
entries for a single day, set planner-diary-include-all-output to

Put the following line of Lisp code in your day plan pages to display
your diary entries:

@example
<lisp>(planner-diary-entries-here)</lisp>
@end example

The function @code{planner-diary-entries-here} takes two optional
arguments---the diary file you want to use and the number of days you
want to display.

@subheading Exporting Planner-specific Diary files

@cindex @file{planner-diary.el}, exporting entries
If you would like to export diary entries from your Planner pages to
separate Diary files, add @code{(require 'planner-export-diary)} to your
config.  The following steps describe the usage of the functions and
options contained in this file.

@enumerate

@item
Customize @code{planner-export-diary-file}.  The default value is
``~/diary.planner''.

@item
Add the following line to your main Diary file (default: ``~/diary'').

@example
#include ~/diary.planner
@end example

@item
Then, call @command{M-x planner-export-diary-future} whenever you want
future diary entries published. You can automatically publish entries by
adding either of the following to your .emacs.

@itemize

@item (planner-export-diary-future)
Publish future entries on startup.

@item (add-hook 'planner-mode-hook 'planner-export-diary-setup)
Publish future entries whenever you save a Planner file.

According to your preferences, you may choose from two different
approaches. Appointments in task descriptions on today's plan
page are like this:

@noindent
and appointments in today's schedule section are like this:

If you don't want to do the insinuation then you can call:

@example
M-x planner-appt-update
@end example

@noindent
after editing appointments on the page (note that this is not
necessary if you use tasks for the appointments and you don't edit
the task descriptions outside of @code{planner-edit-task-description}).

Try both methods; if you find that you prefer one over the
other, use one of the specific @code{planner-appt-use-} functions, as
there are some performance gains when using one method exclusively.

@cindex task-based appointments

A task has an appointment if it looks like this:

@example
#A   _ @@12:45 Do something (TaskPool)
@end example

@noindent
i.e., if it has @@ followed by a time at the beginning.  This means
the task is a regular appointment, and will not be carried forward
at the start of a new day.

Alternatively, it may have a !, like this:

@example
#A   _ !12:45 Do something else (TaskPool)
@end example

@noindent
This makes it a "nagging" appointment, which @emph{will} be carried
forward.  It will, however, lose the appointment time in the
process.

This may seem like a strange feature, but here is Henrik's
reasoning:

@quotation
Sometimes I have a task that I want to do at a certain time, so I
make it an appointment.  If I don't get around to doing it anyway,
I want it to be carried forward.  Basically, I sometimes use
appointments on tasks to annoy me until I get them done. :)
@end quotation

You can edit, move and delete tasks with the usual functions, and
appointments will be updated automatically.

You can update all task appointments on your page with

@example
M-x planner-appt-update
@end example

@c @noindent
@c @strong{Cyclic Entries}

@unnumberedsubsubsec Cyclic Entries
@cindex appointments, cyclic task entries

If you have @file{planner-cyclic} (@pxref{Cyclic Tasks}) loaded, entries
in your cyclical tasks file such as

@example
Friday #A _ @@12:45 staff meeting
@end example

@noindent
will appear every Friday and there will be an appointment alert set
up.

@c @noindent
@c @strong{Appointments Section}
@unnumberedsubsubsec Appointments Section
@cindex appointments, appointments section

You can have all task-based appointments copied to a separate section,
providing an overview of your appointments.

To do this, add

@example
(setq planner-appt-task-use-appointments-section-flag t)
@end example

@noindent to your configuration, or use @kbd{M-x customize-variable}.

The variable @code{planner-appt-task-appointments-section} is the name
of the section where the appointments will be copied.  By default, it is
set to @code{"Schedule"}, which means that task appointments will be
intermingled with schedule entries.

It is also a good idea to add the section you wish to use to
@code{planner-day-page-template} in order to control where that section
will appear on the page (otherwise it will appear at the top).

The format of the appointments follows that of a schedule; if you
don't like the way it looks, you can write something different and set
@code{planner-appt-format-appt-section-line-function} appropriately.
See the documentation for
@code{planner-appt-format-appt-section-line-function} for details.  It
should be fairly easy to see what needs to be done if you look at the
source for the default function (which is
@code{planner-appt-format-appt-section-line}).

If the section specified in
@code{planner-appt-task-appointments-section} is the same as the
schedule section specified in @code{planner-appt-schedule-section} (by
default @code{"Schedule"}), the default formatting function adds a
@samp{#} to the description so that one can visually distinguish
appointments from the task list from those that have been added to the
schedule.

If you add @code{(require 'planner-timeclock-summary)} to your
@file{~/.emacs}, you can then use it in two ways.

@itemize

@item Display a temporary buffer

Call @code{planner-timeclock-summary-show} and Emacs will ask you which
day's summary do you want. Choose the date as anywhere else of
Emacs planner, and a tempory buffer will be displayed with the
timeclock summary of that day.

To review tasks over a date range, use
@code{planner-timeclock-summary-show-range}. You can use a regexp or a
function to filter tasks by calling
@code{planner-timeclock-summary-show-range-filter}.

@item Rewrite sections of your planner

Choose this approach if you want timeclock summary to be in their
own section and you would like them to be readable in your plain
text files even outside Emacs. Caveat: The timeclock summary
section should already exist in your template and will be rewritten
when updated. Tip: Add @code{planner-timeclock-summary-section}
(default: @samp{"Timeclock"}) to your @code{planner-day-page-template}.

To use, call @code{planner-timeclock-summary-update} in the planner
day page to update the section. If you want rewriting to be
automatically performed, call
@code{planner-timeclock-summary-insinuate} in your @file{.emacs} file.
@end itemize

@file{planner-timeclock-summary-proj.el} produces task / time
breakdowns on plan pages. Reports are of the form:

@example
TASK 0 | duration
TASK 1 | duration
 TOTAL | duration.
@end example

To use, add @code{(require 'planner-timeclock-summary)} to your
@file{~/.emacs}. Call @code{planner-timeclock-summary-proj-current}
from a project page. The report is inserted at the current position in
the buffer. The function @code{planner-timeclock-summary-proj-section}
does the same but the report is inserted inside a section called
@samp{* Report}.

@file{planner-schedule.el} allows you to project task completion time.
Tasks should be of the form:

@example
#A0 _ 2h Do something
#B0 _ 1h30m Do something
#B0 _ 2d Do something
#B0 _ 2w Do something
#B0 _ 10s Do something

s: seconds, m: minutes, h: hours, d: days, w: weeks
@end example

@file{schedule.el} is included with Planner in the @file{contrib}
directory, but you can alternatively get it from
@url{http://www.newartisans.com/johnw/Emacs/schedule.el} if desired.

@file{schedule.el} provides a single Lisp function,
@code{schedule-completion-time}. It takes an Emacs time object and a
quantity of seconds. It returns an Emacs time object that represents
when the given number of seconds will be completed, assuming that work
can only be done during work hours.

The available work hours are affected by several factors:

@enumerate

@item
If @file{timeclock.el} is being used, the amount of time left in the
current work day (@code{timeclock-workday-remaining})
(@pxref{Time Intervals, , , Emacs, GNU Emacs Manual})

@item
The amount of time in each work day (@code{schedule-workday})

@item
The definition of a work week (@code{schedule-week})

@item
Any holidays defined in the Emacs calendar
(@pxref{Holidays, , , Emacs, GNU Emacs Manual})

@item
Any appointments in the Emacs diary
(@pxref{Appointments, , , Emacs, GNU Emacs Manual})

@end enumerate

Taking all of the ``block out'' periods into account,
@code{schedule-completion-time} will compute when the given number of
seconds will be done, based on your current definitions of time
available.

As an example, here's a function which, given a list of durations
in seconds, will return a list of completion times starting from
the current moment:

@example

  (defun compute-completion-times (&rest durations)
    ``Compute completion times for a list of DURATIONS (in seconds).''
    (let ((now (current-time)))
      (mapcar
       (function
        (lambda (dura)
          (setq now (schedule-completion-time now dura))))
       durations)))

@end example

To call this function, do:

@example

(compute-completion-times 3600 7200 3600)

@end example

With the variable @code{planner-day-page-template}, you can define how
you want any newly created day planner pages to look.

You might want to include a section for your diary entries. For how to
do this, see @ref{Diary}.

You can add interactive Lisp buttons with the @file{planner-lisp.el}
module. (@pxref{Interactive Lisp})

Your @code{planner-day-page-template} can also include @samp{|<lisp>|}
tags.

For more complex day pages, you can set
@code{planner-day-page-template} to a function that will be called
from an empty day page buffer. The function should initialize the
contents of the day page.

@section Keeping Track of Time

One of the coolest things you can do with Planner is keep track of how
much time you spend not only on projects but even on particular tasks.
@file{planner-timeclock.el} makes it as easy and natural as marking a
task as in progress, postponed, or done. This can help you determine
just how much time you spend working each day. If you add estimates to
your task descriptions, you'll also be able to use this information to
improve your time estimation skills.

Here's how you can keep track of the time you


Then the fun began. I wanted to see if I could match my estimates.
Before I started working on a task, I used @kbd{C-c TAB} to mark it
@code{in progress} and start the clock. If I decided to work on
something else, I used @kbd{C-c TAB} to clock out of the previous task
and clock into the new one.

When I finished it, I used @kbd{C-c C-x} (@code{planner-task-done}) to
mark it completed and automatically clock out. This is not yet done
for cancelled tasks, so I clocked out of those manually with @kbd{C-c
C-o} (@code{timeclock-out}). I also clocked out whenever I caught
myself being distracted so that the totals wouldn't include the time I
spent chatting on #emacs or checking out del.icio.us links. =) At the
end of the day, I used
@code{planner-timeclock-summary-show-range-filter} to show me the time
elapsed for all of the tasks I'd worked on over the past two days.
Here's the report for that project, edited to reflect how it looks on
my screen and annotated with comments:

@end example

The time record isn't perfect. I cancelled some tasks after thinking
about them a little and did some tasks simultaneously. Sometimes I
didn't notice that I was getting distracted, too. Still, having all of
that time information neatly summarized made me realize a number of
things.

First, I goof off much less when I have a nice, broken-down task list
in front of me. There's just something about knowing there's a five-
or ten-minute hack you can get out of the way. I found myself looking
forward to getting to the next task just to see if I could make my
estimate. That said, seeing a five-minute task stretch and stretch due
to unforeseen problems did make me a little nervous. I should probably
just make generous estimates so that I don't end up with bugs because
of haste.

Second, I don't goof off as much as I thought I did, although there's
still room for improvement. Yesterday's workday was 9:00 - 12:00, 1:00
- 5:30--7.5 hours. Today was the last day of work, so cleaning and
celebration interrupted my hacking at around 3:00--5 hours of work.
According to my task list, 10:41/12:30 was productive work. Hmm. 1:49
hours unclocked time when I was thinking or goofing off.
planner-timeclock-summary-show for today reveals that I actually
clocked 5:30 today, which means the goofing off happened yesterday.
That makes sense; I remember a pretty long unclocked segment
recuperating from Japanese overload. (This was before we came up with
the task list.)

Third, keeping track of time is way, way cool even if you don't bill
anyone for your time.

Like the idea? It's easy to try out. Just add

@example
(require 'planner-timeclock)
(require 'planner-timeclock-summary)
@end example

to your ~/.emacs. If you want to try it out now, eval those statements
in your Emacs session. After that, simply use @kbd{C-c TAB} to ``clock
in'' a task before you start working on it and @kbd{C-c C-x}
(@code{planner-task-done}) to mark it completed. @kbd{M-x
planner-task-pending} also clocks out the current task if it was
clocked in. To see a summary of how you spent your day, check out the
different functions in @file{planner-timeclock-summary}.

See @ref{Timeclock} for more details.

Happy hacking!

With @file{planner.el} loaded, you can use any of the functions in this
section by typing @kbd{M-x} followed by the name of the function. Many
of these functions are also bound to keys.

For a list of Planner keybindings, see @ref{Planner Keybindings}.

They are listed in no particular order.

@file{planner.el} defines the following interactive functions:


@defun planner-create-high-priority-task-from-buffer

@code{planner-create-task-from-buffer}.
@end defun

@defun planner-install-extra-context-keybindings
Install extra context-sensitive keybindings. These keybindings
conflict with @file{windmove.el}, but might be useful.
@end defun

@defun planner-narrow-to-section section &optional create
Widen to the whole page and narrow to the section labelled
@var{section}.  If @var{create} is non-nil and the section is not found,
the section is created.  Return non-nil if @var{section} was found or
created.
@end defun

@defun planner-save-buffers
Save all planner-mode buffers.
@end defun

@defun planner-seek-to-first section
Positions the point at the specified @var{section}, or @samp{Tasks} if
not specified.

@end defun

@defun planner-calendar-insinuate
This hooks Planner into  Emacs Calendar (@pxref{Calendar/Diary, ,
, Emacs, GNU Emacs Manual}).

It adds special planner key bindings to @code{calendar-mode-map}.
After this function is evaluated, you can use the following
planner-related keybindings in @code{calendar-mode-map}:

@table @kbd

@item  n
Jump to the planner page for the current day.

@item  N
Display the planner page for the current day.
@end table

@end defun

@defun planner-kill-calendar-files
Remove planner files shown from Calendar (@pxref{Calendar/Diary, , ,

@end defun

@defun planner-jump-to-link
Jump to the item linked to by the current item.
@end defun

@defun planner-move-up
Move a task up. You can use this to indicate that you will do a task
before another one. On a note, go to the previous note. On a headline,
go to the previous headline of the same depth.
@end defun

@defun planner-move-down 
Move down. You can use this to indicate that you will do a task after
another one. On a note, go to the next note. On a headline, go to the

@kbd{M-x planner-renumber-tasks}.

Here is a summary of the keystrokes available:

@table @kbd

@item M-x plan
Begin your planning session.  This goes to the last day for which
there is any planning info (or today if none), allowing you to review,
and create/move tasks from that day.

@item C-c C-u
Move a task up.

@item C-c C-d
Move a task down.

@item C-c C-s
Mark the task as in progress or delegated.

@item C-c C-x
Mark the task as finished.

@item C-c C-t
Create a task associated with the current Wiki page. If you are on the
opening line of a Note entry, it is assumed that the note itself is the
origin of the task.

@item C-c C-c
Move or copy the current task to another date. If the current task is
an original (meaning you are in the buffer where's defined, hopefully
a planning page) then it will be copied, and the original task will
also now point to the copy.  If the current task is a copy, it will
just be moved to the new day, and the original task's link will be
updated.

@item C-c C-n
Jump to today's task page.  If you call
@code{(planner-calendar-insinuate)}, typing @kbd{n} in the Emacs
calendar (@pxref{Calendar/Diary, , , Emacs, GNU Emacs Manual}) will jump
to today's task page.

This section includes some sample configuration files. This way, once
you've got the hang of the basics, you can see some different, more
advanced, setups.

There is no One True Way to plan. Every person is different. We hope
you'll find a good starting point among the example configurations
below. If what you want to do does not perfectly fit under one of these
examples, please post a description of the way you plan to our mailing
list (@pxref{Getting Help}).  We look forward to helping you customizing
planner to fit your needs.

@node File Organization, Bare-Bones Planning, Sample Configuration Files, Sample Configuration Files
@subsection File Organization

@itemize
@item @strong{Tasks, schedule and notes on day pages.}

By default, tasks, schedule entries and notes are filed on day pages.
This makes it easy for you to see all the entries relevant to a single
day without becoming overwhelmed with information. Unfinished tasks
are carried over to the next day when you use @kbd{M-x plan}, so it's
always kept up to date. Completed tasks are left on the day page you
finished them on, which helps when reviewing one's progress and writing
accomplishment reports.

@item @strong{Cross-referenced with plan pages.}

You can associate your tasks with projects either when you create the
task or later, with @kbd{M-x planner-replan-task}. This makes it easy
for you to see all the information associated with a particular
project. If you use RememberMode to create notes, you will also be
able to associate notes with a plan page.

@item @strong{Just plan pages.}

If your tasks don't usually have dates, you can turn day pages off by
customizing @code{planner-use-day-pages}. If so, then all of your
tasks and notes will be stored on the WelcomePage and/or a plan page.

@end itemize

@node Bare-Bones Planning, Bare-Bones Planning with Plan Pages, File Organization, Sample Configuration Files
@subsection Bare-Bones Planning

You can keep all of your tasks, notes and schedules in a single file:
WelcomePage.  This is good for people who are used to storing all of
their information in a flat text file.  By storing your information in
planner, you'll be able to take advantage of automatic hyperlinking to
files and other resources.  You can also sort your tasks by priority
and status.

To set your system up for bare-bones planning, set the
@code{planner-use-day-pages} variable to nil before loading planner.
For example, you can put this in your @file{~/.emacs} (or @file{_emacs}):

@example
(setq planner-use-day-pages nil)
(setq planner-default-page nil)
(require 'planner)
@end example

When you create a task or note, planner will not prompt you for a
date.  If you press @key{RET} when prompted for a plan page, it will
accept the default of nil, so no other plan pages will be used.  All
of your data will be kept in one file, which can then be easily backed
up.

You can use commands like @command{planner-create-task-from-buffer} to
create tasks, or you can type tasks in manually.  You can edit or
delete anything in the page without having to update other files.

@node Bare-Bones Planning with Plan Pages, Tasks on Plan Pages with Some Day Pages, Bare-Bones Planning, Sample Configuration Files
@subsection Bare-Bones Planning with Plan Pages

When you create a task or note, Planner.el can copy this to a plan
page. Plan pages allow you to see an overview of all the data for a
project.

For convenience, the @command{planner-create-task-from-buffer} command
prompts you for a plan page when you create a task.



@node Tasks on Plan Pages with Some Day Pages, Hierarchical Tasks, Bare-Bones Planning with Plan Pages, Sample Configuration Files
@subsection Tasks on Plan Pages with Some Day Pages

If most of your tasks are associated with plan pages but you want to
schedule some tasks on day pages, you can leave day pages on (default)
and then write a function that turns off day pages. For example, the
following code snippet turns off day pages for task creation from
buffers.

@example
(require 'planner)

(defun my-planner-create-task-from-buffer ()
  "Call `planner-create-task-from-buffer', but without dates."
  (interactive)
  (let ((planner-use-day-pages nil))
    (call-interactively 'planner-create-task-from-buffer)))
@end example

@node Hierarchical Tasks,  , Tasks on Plan Pages with Some Day Pages, Sample Configuration Files
@subsection Hierarchical Tasks
@cindex hierarchical tasks
@cindex tasks, hierarchy of

You can use @file{allout.el} or other modes for outlining to support
hierarchical tasks in plan pages. No special support is needed.

Tasks created by @command{planner-create-task-from-buffer} and
@code{planner-create-task} are created in the @samp{* Tasks} section.
If @code{planner-add-task-at-end-flag} is non-nil, tasks are added to
the end of the first task block, else they are added to the beginning.
You can then copy and paste tasks into your preferred hierarchy.
Blank lines delimit blocks of tasks upon which automatic sorting is
performed.

You can also type in tasks manually. You may find this approach faster
when you are comfortable with planner.

For example, a @file{LearnPlanner} plan page might contain the
following lines:

@example
* Learn how to use planner.el

** Installation

#C0 _ Decide where to put Planner
#C0 _ Download the archives

** Configuration

*** Load path

#C0 _ Figure out how to add things to my load path
#C0 _ Actually add it to my load path

...
@end example

If you create tasks for the finest level of detail available at the
moment, you can schedule them onto day pages with @kbd{C-c C-c}
(@command{planner-copy-or-move-task}). Then you can use
@command{planner-jump-to-link} to switch between the day page and the
plan page link.

@cindex GPL
@cindex GNU General Public License

@c This file is intended to be included in another file.

@display
Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
@end display

@appendixsec Preamble

  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software---to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.)  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

  To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

  We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

  Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

  Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

  The precise terms and conditions for copying, distribution and
modification follow.

@iftex
@appendixsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
@end iftex
@ifinfo
@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
@end ifinfo

@enumerate 0
@item
This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The ``Program'', below,
refers to any such program or work, and a ``work based on the Program''
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term ``modification''.)  Each licensee is addressed as ``you''.

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

@item
You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

@item
You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

@enumerate a
@item
You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.

@item
You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.

@item
If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License.  (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
@end enumerate

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

@item
You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

@enumerate a
@item
Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,

@item
Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,

@item
Accompany it with the information you received as to the offer
to distribute corresponding source code.  (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
@end enumerate

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

@item
You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

@item
You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

@item
Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

@item
If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

@item
If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

@item
The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and ``any
later version'', you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

@item
If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

@appendixsec Appendix: How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the ``copyright'' line and a pointer to where the full notice is found.

@smallexample
@var{one line to give the program's name and a brief idea of what it does.}
Copyright (C) @var{yyyy}  @var{name of author}

This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.

This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
GNU General Public License for more details.

You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA  02111-1307, USA.
@end smallexample

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

@smallexample
Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author}
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
@end smallexample

The hypothetical commands @samp{show w} and @samp{show c} should show
the appropriate parts of the General Public License.  Of course, the
commands you use may be called something other than @samp{show w} and
@samp{show c}; they could even be mouse-clicks or menu items---whatever
suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a ``copyright disclaimer'' for the program, if
necessary.  Here is a sample; alter the names:

@example
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

@var{signature of Ty Coon}, 1 April 1989
Ty Coon, President of Vice
@end example

This General Public License does not permit incorporating your program into
proprietary programs.  If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library.  If this is what you want to do, use the GNU Library General
Public License instead of this License.
