;;; Commentary:
1992-08-12 12:50:10 +00:00
;; This collection of functions implements a calendar window. It
;; generates a calendar for the current month, together with the previous
;; and coming months, or for any other three-month period. The calendar
;; can be scrolled forward and backward in the window to show months in
;; the past or future; the cursor can move forward and backward by days,
;; weeks, or months, making it possible, for instance, to jump to the
;; date a specified number of days, weeks, or months from the date under
;; the cursor. The user can display a list of holidays and other notable
;; days for the period shown; the notable days can be marked on the
;; calendar, if desired. The user can also specify that dates having
;; corresponding diary entries (in a file that the user specifies) be
;; marked; the diary entries for any date can be viewed in a separate
;; window. The diary and the notable days can be viewed independently of
;; the calendar. Dates can be translated from the (usual) Gregorian
;; calendar to the day of the year/days remaining in year, to the ISO
;; commercial calendar, to the Julian (old style) calendar, to the Hebrew
;; calendar, to the Islamic calendar, to the French Revolutionary calendar,
;; to the Mayan calendar, and to the astronomical (Julian) day number.
;; When floating point is available, times of sunrise/sunset can be displayed,
1993-06-09 11:59:12 +00:00
;; as can the phases of the moon. Appointment notification for diary entries
1992-08-12 12:50:10 +00:00
;; is available.

"*Name of the file in which one's personal diary of dates is kept.
The file's entries are lines in any of the forms
MONTH/DAY
MONTH/DAY/YEAR
MONTHNAME DAY
MONTHNAME DAY, YEAR
DAYNAME
at the beginning of the line; the remainder of the line is the diary entry
string for that date. MONTH and DAY are one or two digit numbers, YEAR is
a number and may be written in full or abbreviated to the final two digits.
If the date does not contain a year, it is generic and applies to any year.
DAYNAME entries apply to any date on which is on that day of the week.
MONTHNAME and DAYNAME can be spelled in full, abbreviated to three
characters (with or without a period), capitalized or not. Any of DAY,
MONTH, or MONTHNAME, YEAR can be `*' which matches any day, month, or year,
respectively.
The European style (in which the day precedes the month) can be used
instead, if you execute `european-calendar' when in the calendar, or set
`european-calendar-style' to t in your .emacs file. The European forms are
DAY/MONTH
DAY/MONTH/YEAR
DAY MONTHNAME
DAY MONTHNAME YEAR
DAYNAME
To revert to the default American style from the European style, execute
`american-calendar' in the calendar.

A diary entry can be preceded by the character
`diary-nonmarking-symbol' (ordinarily `&') to make that entry
nonmarking--that is, it will not be marked on dates in the calendar
window but will appear in a diary window.
1992-05-04 16:48:30 +00:00
Multiline diary entries are made by indenting lines after the first with
either a TAB or one or more spaces.
Lines not in one the above formats are ignored. Here are some sample diary
entries (in the default American style):
12/22/1988 Twentieth wedding anniversary!!
&1/1. Happy New Year!
10/22 Ruth's birthday.
21: Payday
Tuesday--weekly meeting with grad students at 10am
Supowit, Shen, Bitner, and Kapoor to attend.
1/13/89 Friday the thirteenth!!
&thu 4pm squash game with Lloyd.
mar 16 Dad's birthday
April 15, 1989 Income tax due.
&* 15 time cards due.
If the first line of a diary entry consists only of the date or day name with
no trailing blanks or punctuation, then that line is not displayed in the
diary window; only the continuation lines is shown. For example, the
1992-05-04 16:48:30 +00:00
single diary entry
02/11/1989
Bill Blattner visits Princeton today
2pm Cognitive Studies Committee meeting
2:30-5:30 Lizzie at Lawrenceville for `Group Initiative'
4:00pm Jamie Tappenden
7:30pm Dinner at George and Ed's for Alan Ryan
7:30-10:00pm dance at Stewart Country Day School
will appear in the diary window without the date line at the beginning. This
facility allows the diary window to look neater, but can cause confusion if
used with more than one day's entries displayed.
Diary entries can be based on Lisp sexps. For example, the diary entry
%%(diary-block 11 1 1990 11 10 1990) Vacation
causes the diary entry \"Vacation\" to appear from November 1 through November
10, 1990. Other functions available are `diary-float', `diary-anniversary',
1992-08-12 12:50:10 +00:00
`diary-cyclic', `diary-day-of-year', `diary-iso-date', `diary-french-date',
`diary-hebrew-date', `diary-islamic-date', `diary-mayan-date',
`diary-yahrzeit', `diary-sunrise-sunset', `diary-phases-of-moon',
`diary-parasha', `diary-omer', `diary-rosh-hodesh', and
`diary-sabbath-candles'. See the documentation for the function
`list-sexp-diary-entries' for more details.
1992-05-04 16:48:30 +00:00
Diary entries based on the Hebrew and/or the Islamic calendar are also
possible, but because these are somewhat slow, they are ignored
unless you set the `nongregorian-diary-listing-hook' and the
`nongregorian-diary-marking-hook' appropriately. See the documentation
for these functions for details.
Diary files can contain directives to include the contents of other files; for
details, see the documentation for the variable `list-diary-entries-hook'.")

this hook. This function enables you to use shared diary files together
1994-05-08 06:45:49 +00:00
with your own. The files included are specified in the diary file by lines
1992-05-04 16:48:30 +00:00
of the form
#include \"filename\"
This is recursive; that is, #include directives in files thus included are

the variable `diary-include-string'. When you use `include-other-diary-files'
as part of the list-diary-entries-hook, you will probably also want to use the

"Display a three-month calendar in another window.
The three months appear side by side, with the current month in the middle
surrounded by the previous and next months. The cursor is put on today's date.
1992-08-12 12:50:10 +00:00
If called with an optional prefix argument, prompts for month and year.
1992-05-04 16:48:30 +00:00
This function is suitable for execution in a .emacs file; appropriate setting
of the variable `view-diary-entries-initially' will cause the diary entries for
the current date to be displayed in another window. The value of the variable
`number-of-diary-entries' controls the number of days of diary entries
displayed upon initial display of the calendar.
An optional prefix argument ARG causes the calendar displayed to be ARG
months in the future if ARG is positive or in the past if ARG is negative;
in this case the cursor goes on the first day of the month.
Once in the calendar window, future or past months can be moved into view.
Arbitrary months can be displayed, or the calendar can be scrolled forward
or backward.
The cursor can be moved forward or backward by one day, one week, one month,
or one year. All of these commands take prefix arguments which, when negative,
cause movement in the opposite direction. For convenience, the digit keys
and the minus sign are automatically prefixes. The window is replotted as
necessary to display the desired date.
Diary entries can be marked on the calendar or displayed in another window.
Use M-x describe-mode for details of the key bindings in the calendar window.
The Gregorian calendar is assumed.
1992-08-12 12:50:10 +00:00
After loading the calendar, the hooks given by the variable
`calendar-load-hook' are run. This the place to add key bindings to the
calendar-mode-map.
1992-05-04 16:48:30 +00:00
After preparing the calendar window initially, the hooks given by the variable
`initial-calendar-window-hook' are run.
The hooks given by the variable `today-visible-calendar-hook' are run
everytime the calendar window gets scrolled, if the current date is visible
in the window. If it is not visible, the hooks given by the variable
`today-invisible-calendar-hook' are run. Thus, for example, setting
`today-visible-calendar-hook' to 'calendar-star-date will cause today's date
to be replaced by asterisks to highlight it whenever it is in the window."

Whenever it makes sense, the above commands take prefix arguments that
multiply their affect. For convenience, the digit keys and the minus sign
are bound to digit-argument, so they need not be prefixed with ESC.
If the calendar window somehow becomes corrupted, it can be regenerated with
\\[redraw-calendar] redraw the calendar
The following commands deal with holidays and other notable days:
\\[calendar-cursor-holidays] give holidays for the date specified by the cursor
\\[mark-calendar-holidays] mark notable days
\\[calendar-unmark] unmark dates
\\[list-calendar-holidays] display notable days
The command M-x holidays causes the notable dates for the current month, and
the preceding and succeeding months, to be displayed, independently of the
calendar.
The following commands control the diary:
\\[mark-diary-entries] mark diary entries \\[calendar-unmark] unmark dates
\\[view-diary-entries] display diary entries \\[show-all-diary-entries] show all diary entries
\\[print-diary-entries] print diary entries
1994-05-08 06:45:49 +00:00
Displaying the diary entries causes the diary entries from the diary file
\(for the date indicated by the cursor in the calendar window) to be
1992-05-04 16:48:30 +00:00
displayed in another window. This function takes an integer argument that
specifies the number of days of calendar entries to be displayed, starting
with the date indicated by the cursor.
The command \\[print-diary-entries] prints the diary buffer (as it appears)
on the line printer.
The command M-x diary causes the diary entries for the current date to be
displayed, independently of the calendar. The number of days of entries is
governed by number-of-diary-entries.
The format of the entries in the diary file is described in the
1994-05-08 06:45:49 +00:00
documentation string for the variable `diary-file'.
1992-05-04 16:48:30 +00:00
When diary entries are in view in the window, they can be edited. It is
important to keep in mind that the buffer displayed contains the entire
diary file, but with portions of it concealed from view. This means, for
instance, that the forward-char command can put the cursor at what appears
to be the end of the line, but what is in reality the middle of some
concealed line. BE CAREFUL WHEN EDITING THE DIARY ENTRIES! (Inserting
additional lines or adding/deleting characters in the middle of a visible
line will not cause problems; watch out for end-of-line, however--it may
put you at the end of a concealed line far from where the cursor appears to
be!) BEFORE EDITING THE DIARY IT IS BEST TO DISPLAY THE ENTIRE FILE WITH
show-all-diary-entries. BE SURE TO WRITE THE FILE BEFORE EXITING FROM THE
CALENDAR.
The following commands assist in making diary entries:
\\[insert-diary-entry] insert a diary entry for the selected date
\\[insert-weekly-diary-entry] insert a diary entry for the selected day of the week
\\[insert-monthly-diary-entry] insert a diary entry for the selected day of the month
\\[insert-yearly-diary-entry] insert a diary entry for the selected day of the year
\\[insert-block-diary-entry] insert a diary entry for the block days between point and mark
\\[insert-anniversary-diary-entry] insert an anniversary diary entry for the selected date
\\[insert-cyclic-diary-entry] insert a cyclic diary entry
There are corresponding commands to assist in making Hebrew- or Islamic-date
diary entries:
\\[insert-hebrew-diary-entry] insert a diary entry for the Hebrew date corresponding
to the selected date
\\[insert-monthly-hebrew-diary-entry] insert a diary entry for the day of the Hebrew month
corresponding to the selected day
\\[insert-yearly-hebrew-diary-entry] insert a diary entry for the day of the Hebrew year
corresponding to the selected day
\\[insert-islamic-diary-entry] insert a diary entry for the Islamic date corresponding
to the selected date
\\[insert-monthly-islamic-diary-entry] insert a diary entry for the day of the Islamic month
corresponding to the selected day
\\[insert-yearly-islamic-diary-entry] insert a diary entry for the day of the Islamic year
corresponding to the selected day
All of the diary entry commands make nonmarking entries when given a prefix
argument; with no prefix argument, the diary entries are marking.
The day number in the year and the number of days remaining in the year can be
determined by
1992-08-12 12:50:10 +00:00
\\[calendar-print-day-of-year] show day number and the number of days remaining in the year
Equivalent dates on the ISO commercial, Julian, Hebrew, Islamic, French
Revolutionary, and Mayan calendars can be determined by
1992-05-04 16:48:30 +00:00
1992-08-12 12:50:10 +00:00
\\[calendar-print-iso-date] show equivalent date on the ISO commercial calendar
\\[calendar-print-julian-date] show equivalent date on the Julian calendar
\\[calendar-print-hebrew-date] show equivalent date on the Hebrew calendar
\\[calendar-print-islamic-date] show equivalent date on the Islamic calendar
\\[calendar-print-french-date] show equivalent date on the French Revolutionary calendar
\\[calendar-print-mayan-date] show equivalent date on the Mayan calendar
1992-05-04 16:48:30 +00:00
1993-06-09 11:59:12 +00:00
The astronomical (Julian) day number of a date is found with
1992-08-12 12:50:10 +00:00
\\[calendar-print-astro-day-number] show equivalent astronomical (Julian) day number
To find the times of sunrise and sunset and lunar phases use
\\[calendar-sunrise-sunset] show times of sunrise and sunset
\\[calendar-phases-of-moon] show times of quarters of the moon
The times given apply to location `calendar-location-name' at latitude
`calendar-latitude', longitude `calendar-longitude'; set these variables for
your location. The following variables are also consulted, and you must set
them if your system does not initialize them properly: `calendar-time-zone',
`calendar-daylight-time-offset', `calendar-standard-time-zone-name',
`calendar-daylight-time-zone-name', `calendar-daylight-savings-starts',
`calendar-daylight-savings-ends', `calendar-daylight-savings-starts-time',
`calendar-daylight-savings-ends-time'.
1992-05-04 16:48:30 +00:00
To exit from the calendar use
\\[exit-calendar] exit from calendar
Set `view-diary-entries-initially' to a non-nil value to display
diary entries for the current date in
1992-05-04 16:48:30 +00:00
another window when the calendar is first displayed, if the current date is
visible. The variable `number-of-diary-entries' controls number of days of
diary entries that to display initially or with the command M-x
diary. For example, the default value 1 says to display only the current
day's diary entries. The value 2 says to display both the
current day's and the next day's entries.
The value can also be a vector such as [0 2 2 2 2 4 1]; this value
says to display no diary entries on Sunday, the display the entries
for the current date and the day after on Monday through Thursday,
display Friday through Monday's entries on Friday, and display only
Saturday's entries on Saturday.
Set `view-calendar-holidays-initially' to a non-nil value to display
holidays for the current three month period on entry to the calendar.
Set `mark-diary-entries-in-calendar' to a non-nil value to mark in the
calendar all the dates that have diary entries. The variable
`diary-entry-marker' controls how to mark them.
1992-08-12 12:50:10 +00:00
The variable `calendar-load-hook', whose default value is nil, is list of
functions to be called when the calendar is first loaded.
The variable `initial-calendar-window-hook', whose default value is nil, is
list of functions to be called when the calendar window is first opened. The
functions invoked are called after the calendar window is opened, but once
opened is never called again. Leaving the calendar with the `q' command and
reentering it will cause these functions to be called again.
The variable `today-visible-calendar-hook', whose default value is nil, is the
list of functions called after the calendar buffer has been prepared with the
calendar when the current date is visible in the window. This can be used,
for example, to replace today's date with asterisks; a function
calendar-star-date is included for this purpose:
(setq today-visible-calendar-hook 'calendar-star-date)
It could also be used to mark the current date; a function is also provided
for this:
(setq today-visible-calendar-hook 'calendar-mark-today)
1992-08-12 12:50:10 +00:00
The variable `today-invisible-calendar-hook', whose default value is nil, is
the list of functions called after the calendar buffer has been prepared with
the calendar when the current date is not visible in the window.
The variable `diary-display-hook' is the list of functions called after the
diary buffer is prepared. The default value simply displays the diary file
using selective-display to conceal irrelevant diary entries. An alternative
function `fancy-diary-display' is provided that, when used as the
`diary-display-hook', causes a noneditable buffer to be prepared with a neatly
organized day-by-day listing of relevant diary entries, together with any
known holidays. The inclusion of the holidays slows this fancy display of the
diary; to speed it up, set the variable `holidays-in-diary-buffer' to nil.
The variable `print-diary-entries-hook' is the list of functions called after
a temporary buffer is prepared with the diary entries currently visible in the
diary buffer. The default value of this hook adds a heading (composed from
the diary buffer's mode line), does the printing with the command lpr-buffer,
and kills the temporary buffer. Other uses might include, for example,
rearranging the lines into order by day and time.

"Concatenate list of STRINGS separated with copies of CHAR to fill LENGTH
