;;; Commentary:

;; This file contains the code for creating and using the Agenda for Org.
;;
;; The functions `org-batch-agenda', `org-batch-agenda-csv', and
;; `org-batch-store-agenda-views' are implemented as macros to provide
;; a convenient way for extracting agenda information from the command
;; line.  The Lisp does not evaluate parameters of a macro call; thus
;; it is not necessary to quote the parameters passed to one of those
;; functions.  E.g. you can write:
;;
;;   emacs -batch -l ~/.emacs -eval '(org-batch-agenda "a" org-agenda-span 7)'
;;
;; To export an agenda spanning 7 days.  If `org-batch-agenda' would
;; have been implemented as a regular function you'd have to quote the
;; symbol org-agenda-span.  Moreover: To use a symbol as parameter
;; value you would have to double quote the symbol.
;;
;; This is a hack, but it works even when running Org byte-compiled.

This variable is a list of symbols that controls the types of

list are

  :timestamp   List items containing a date stamp or date range matching
               the selected date.  This includes sexp entries in angular
               brackets.

  :sexp        List entries resulting from plain diary-like sexps.

  :deadline    List deadline due on that date.  When the date is today,
               also list any deadlines past due, or due within
	       `org-deadline-warning-days'.

  :deadline*   Same as above, but only include the deadline if it has an
               hour specification as [h]h:mm.

  :scheduled   List all items which are scheduled for the given date.
	       The diary for *today* also contains items which were
	       scheduled earlier and are not yet marked DONE.

  :scheduled*  Same as above, but only include the scheduled item if it

By default, all four non-starred types are turned on.

When :scheduled* or :deadline* are included, :schedule or :deadline
will be ignored.

Never set this variable globally using `setq', because then it
will apply to all future agenda commands.  Instead, bind it with
`let' to scope it dynamically into the agenda-constructing
command.  A good way to set it is through options in
`org-agenda-custom-commands'.  For a more flexible (though
somewhat less efficient) way of determining what is included in
the daily/weekly agenda, see `org-agenda-skip-function'.")

  "Custom commands for the agenda.
\\<org-mode-map>
These commands will be offered on the splash screen displayed by the
agenda dispatcher `\\[org-agenda]'.  Each entry is a list like this:

   (key desc type match settings files)

key      The key (one or more characters as a string) to be associated
         with the command.
desc     A description of the command, when omitted or nil, a default
         description is built using MATCH.
type     The command type, any of the following symbols:
          agenda      The daily/weekly agenda.
          todo        Entries with a specific TODO keyword, in all agenda files.
          search      Entries containing search words entry or headline.
          tags        Tags/Property/TODO match in all agenda files.
          tags-todo   Tags/P/T match in all agenda files, TODO entries only.
          todo-tree   Sparse tree of specific TODO keyword in *current* file.
          tags-tree   Sparse tree with all tags matches in *current* file.
          occur-tree  Occur sparse tree for *current* file.
          ...         A user-defined function.
match    What to search for:
          - a single keyword for TODO keyword searches
          - a tags/property/todo match expression for searches
          - a word search expression for text searches.
          - a regular expression for occur searches
          For all other commands, this should be the empty string.
settings  A list of option settings, similar to that in a let form, so like
          this: ((opt1 val1) (opt2 val2) ...).   The values will be
          evaluated at the moment of execution, so quote them when needed.
files     A list of files to write the produced agenda buffer to with
          the command `org-store-agenda-views'.
          If a file name ends in \".html\", an HTML version of the buffer
          is written out.  If it ends in \".ps\", a postscript version is
          produced.  Otherwise, only the plain text is written to the file.

You can also define a set of commands, to create a composite agenda buffer.
In this case, an entry looks like this:

  (key desc (cmd1 cmd2 ...) general-settings-for-whole-set files)

where

desc   A description string to be displayed in the dispatcher menu.
cmd    An agenda command, similar to the above.  However, tree commands
       are not allowed, but instead you can get agenda and global todo list.
       So valid commands for a set are:
       (agenda \"\" settings)
       (alltodo \"\" settings)
       (stuck \"\" settings)
       (todo \"match\" settings files)
       (search \"match\" settings files)
       (tags \"match\" settings files)
       (tags-todo \"match\" settings files)

Each command can carry a list of options, and another set of options can be
given for the whole set of commands.  Individual command options take
precedence over the general options.

When using several characters as key to a command, the first characters
are prefix commands.  For the dispatcher to display useful information, you
should provide a description for the prefix, like

 (setq org-agenda-custom-commands
   \\='((\"h\" . \"HOME + Name tag searches\") ; describe prefix \"h\"
     (\"hl\" tags \"+HOME+Lisa\")
     (\"hp\" tags \"+HOME+Peter\")
     (\"hk\" tags \"+HOME+Kim\")))"

This is a list of four items:

   See the manual for a description of tag and property searches.
   The entire tree below a headline matched by this is considered one project.
2. A list of TODO keywords identifying non-stuck projects.
   If the project subtree contains any headline with one of these todo
   keywords, the project is considered to be not stuck.  If you specify
   \"*\" as a keyword, any TODO keyword will mark the project unstuck.
3. A list of tags identifying non-stuck projects.
   If the project subtree contains any headline with one of these tags,
   the project is considered to be not stuck.  If you specify \"*\" as
   a tag, any tag will mark the project unstuck.  Note that this is about
   the explicit presence of a tag somewhere in the subtree, inherited
   tags do not count here.  If inherited tags make a project not stuck,
   use \"-TAG\" in the tags part of the matcher under (1.) above.
4. An arbitrary regular expression matching non-stuck projects.

If the project turns out to be not stuck, search continues also in the
subtree to see if any of the subtasks have project status.

See also the variable `org-tags-match-list-sublevels' which applies
to projects matched by this search as well.

After defining this variable, you may use `org-agenda-list-stuck-projects'

  "Format specifications for the prefix of items in the agenda views.

An alist with one entry per agenda type.  The keys of the
sublists are `agenda', `todo', `search' and `tags'.  The values
are format strings.

This format works similar to a printf format, with the following meaning:

  %c   the category of the item, \"Diary\" for entries from the diary,
       or as given by the CATEGORY keyword or derived from the file name
  %e   the effort required by the item
  %l   the level of the item (insert X space(s) if item is of level X)
  %i   the icon category of the item, see `org-agenda-category-icon-alist'
  %T   the last tag of the item (ignore inherited tags, which come first)
  %t   the HH:MM time-of-day specification if one applies to the entry
  %s   Scheduling/Deadline information, a short string
  %b   show breadcrumbs, i.e., the names of the higher levels
  %(expression) Eval EXPRESSION and replace the control string
                by the result

All specifiers work basically like the standard `%s' of printf, but may
contain two additional characters: a question mark just after the `%'
and a whitespace/punctuation character just before the final letter.

If the first character after `%' is a question mark, the entire field
will only be included if the corresponding value applies to the current
entry.  This is useful for fields which should have fixed width when
present, but zero width when absent.  For example, \"%?-12t\" will
result in a 12 character time field if a time of the day is specified,
but will completely disappear in entries which do not contain a time.

If there is punctuation or whitespace character just before the
final format letter, this character will be appended to the field
value if the value is not empty.  For example, the format
\"%-12:c\" leads to \"Diary: \" if the category is \"Diary\".  If
the category is empty, no additional colon is inserted.

The default value for the agenda sublist is \"  %-12:c%?-12t% s\",
which means:

- Indent the line with two space characters
- Give the category a 12 chars wide field, padded with whitespace on
  the right (because of `-').  Append a colon if there is a category
  (because of `:').
- If there is a time-of-day, put it into a 12 chars wide field.  If no
  time, don't put in an empty field, just skip it (because of '?').
- Finally, put the scheduling information.

not-in-buffer: command not displayed in matching buffers
   [function]: a custom function taking no argument

If you define several checks, the agenda command will be
accessible if there is at least one valid check.

You can also bind a key to another agenda custom command
depending on contextual rules.

    \\='((\"p\" \"q\" ((in-file . \"\\\\.txt\\\\'\"))))

  "Dispatch agenda commands to collect entries to the agenda buffer.
Prompts for a command to execute.  Any prefix arg will be passed
on to the selected command.  The default selections are:

a     Call `org-agenda-list' to display the agenda for current day or week.
t     Call `org-todo-list' to display the global todo list.
T     Call `org-todo-list' to display the global todo list, select only
      entries with a specific TODO keyword (the user gets a prompt).
m     Call `org-tags-view' to display headlines with tags matching
      a condition  (the user is prompted for the condition).
M     Like `m', but select only TODO entries, no ordinary headlines.
e     Export views to associated files.
s     Search entries for keywords.
S     Search entries for keywords, only with TODO keywords.
/     Multi occur across all agenda files and also files listed
      in `org-agenda-text-search-extra-files'.
<     Restrict agenda commands to buffer, subtree, or region.
      Press several times to get the desired effect.
>     Remove a previous restriction.
#     List \"stuck\" projects.
!     Configure what \"stuck\" means.
C     Configure custom agenda commands.

More commands can be added by configuring the variable
`org-agenda-custom-commands'.  In particular, specific tags and TODO keyword
searches can be pre-defined in this way.

If the current buffer is in Org mode and visiting a file, you can also
first press `<' once to indicate that the agenda should be temporarily
\(until the next use of `\\[org-agenda]') restricted to the current file.
Pressing `<' twice means to restrict to the current subtree or region
\(if active)."

START-DAY defaults to TODAY, or to the most recent match for the weekday

When WITH-HOUR is non-nil, only include scheduled and deadline
items if they have an hour specification like [h]h:mm."

  "Show all entries that contain a phrase or words or regular expressions.

With optional prefix argument TODO-ONLY, only consider entries that are
TODO entries.  The argument STRING can be used to pass a default search
string into this function.  If EDIT-AT is non-nil, it means that the
user should get a chance to edit this string, with cursor at position
EDIT-AT.

The search string can be viewed either as a phrase that should be found as
is, or it can be broken into a number of snippets, each of which must match
in a Boolean way to select an entry.  The default depends on the variable
`org-agenda-search-view-always-boolean'.
Even if this is turned off (the default) you can always switch to
Boolean search dynamically by preceding the first word with  \"+\" or \"-\".

The default is a direct search of the whole phrase, where each space in
the search string can expand to an arbitrary amount of whitespace,
including newlines.

If using a Boolean search, the search string is split on whitespace and
each snippet is searched separately, with logical AND to select an entry.
Words prefixed with a minus must *not* occur in the entry.  Words without
a prefix or prefixed with a plus must occur in the entry.  Matching is
case-insensitive.  Words are enclosed by word delimiters (i.e. they must
match whole words, not parts of a word) if
`org-agenda-search-view-force-full-words' is set (default is nil).

Boolean search snippets enclosed by curly braces are interpreted as
regular expressions that must or (when preceded with \"-\") must not
match in the entry.  Snippets enclosed into double quotes will be taken
as a whole, to include whitespace.

- If the search string starts with an asterisk, search only in headlines.
- If (possibly after the leading star) the search string starts with an
  exclamation mark, this also means to look at TODO entries only, an effect
  that can also be achieved with a prefix argument.
- If (possibly after star and exclamation mark) the search string starts
  with a colon, this will mean that the (non-regexp) snippets of the
  Boolean search must match as full words.

This command searches the agenda files, and in addition the files
listed in `org-agenda-text-search-extra-files' unless a restriction lock
is active."

If SUBTREE is non-nil, the entire subtree is checked.  Otherwise, only

CONDITIONS is a list of symbols, boolean OR is used to combine the results
from different tests.  Valid conditions are:

scheduled     Check if there is a scheduled cookie
notscheduled  Check if there is no scheduled cookie
deadline      Check if there is a deadline
notdeadline   Check if there is no deadline
timestamp     Check if there is a timestamp (also deadline or scheduled)
nottimestamp  Check if there is no timestamp (also deadline or scheduled)
regexp        Check if regexp matches
notregexp     Check if regexp does not match.
todo          Check if TODO keyword matches
nottodo       Check if TODO keyword does not match

The regexp is taken from the conditions list, it must come right after
the `regexp' or `notregexp' element.

`todo' and `nottodo' accept as an argument a list of todo
keywords, which may include \"*\" to match any todo keyword.

    (org-agenda-skip-entry-if \\='todo \\='(\"TODO\" \"WAITING\"))

would skip all entries with \"TODO\" or \"WAITING\" keywords.

Instead of a list, a keyword class may be given.  For example:

    (org-agenda-skip-entry-if \\='nottodo \\='done)

would skip entries that haven't been marked with any of \"DONE\"
keywords.  Possible classes are: `todo', `done', `any'.

If any of these conditions is met, this function returns the end point of
the entity, causing the search to continue from there.  This is a function
that can be put into `org-agenda-skip-function' for the duration of a command."

  "Return diary information from org files.
This function can be used in a \"sexp\" diary entry in the Emacs calendar.
It accesses org files and extracts information from those files to be
listed in the diary.  The function accepts arguments specifying what
items should be listed.  For a list of arguments allowed here, see the
variable `org-agenda-entry-types'.

The call in the diary file should look like this:

   &%%(org-diary) ~/path/to/some/orgfile.org

Use a separate line for each org file to check.  Or, if you omit the file name,
all files listed in `org-agenda-files' will be checked automatically:

   &%%(org-diary)

If you don't give any arguments (as in the example above), the default value
of `org-agenda-entry-types' is used: (:deadline :scheduled :timestamp :sexp).
So the example above may also be written as

   &%%(org-diary :deadline :timestamp :sexp :scheduled)

The function expects the lisp variables `entry' and `date' to be provided
by the caller, because this is how the calendar works.  Don't use this
function from a program - use `org-agenda-get-day-entries' instead."

Multiple filter elements can be concatenated without spaces, for example

     +work-John<0:10-/plot/

selects entries with category `work' and effort estimates below 10 minutes,
and deselects entries with tag `John' or matching the regexp `plot'.

During entry of the filter, completion for tags, categories and effort
values is offered.  Since the syntax for categories and tags is identical
there should be no overlap between categories and tags.  If there is, tags
get priority.

A single `\\[universal-argument]' prefix arg STRIP-OR-ACCUMULATE will negate the
entire filter, which can be useful in connection with the prompt history.

A double `\\[universal-argument] \\[universal-argument]' prefix arg will add the new filter elements to the
existing ones.  A shortcut for this is to add an additional `+' at the
beginning of the string, like `+-John'.

With a triple prefix argument, execute the computed filtering defined in
the variable `org-agenda-auto-exclude-function'."

With a `\\[universal-argument]' prefix, refresh the list of \

If FILTER is t, interactively prompt the user for a regular
expression, and filter out entries that don't match it.

If FILTER is a string, use this string as a regular expression
for filtering entries out.

If FILTER is a function, filter out entries against which
calling the function returns nil.  This function takes one
argument: an entry from `org-agenda-get-day-entries'.

FILTER can also be an alist with the car of each cell being
either `headline' or `category'.  For example:

  \\='((headline \"IMPORTANT\")
    (category \"Work\"))

will only add headlines containing IMPORTANT or headlines
belonging to the \"Work\" category.

ARGS are symbols indicating what kind of entries to consider.
By default `org-agenda-to-appt' will use :deadline*, :scheduled*
\(i.e., deadlines and scheduled items with a hh:mm specification)
and :timestamp entries.  See the docstring of `org-diary' for
details and examples.
