If you set the variable view-diary-entries-initially to
t, calling up the calendar automatically displays the diary
entries for the current date as well. The diary dates appear only if
the current date is visible. If you add both of the following lines to
your `.emacs' file:
(setq view-diary-entries-initially t) (calendar)
this displays both the calendar and diary windows whenever you start Emacs.
Similarly, if you set the variable
view-calendar-holidays-initially to t, entering the
calendar automatically displays a list of holidays for the current
three-month period. The holiday list appears in a separate
window.
You can set the variable mark-diary-entries-in-calendar to
t in order to mark any dates with diary entries. This takes
effect whenever the calendar window contents are recomputed. There are
two ways of marking these dates: by changing the face (see section Faces),
if the display supports that, or by placing a plus sign (`+')
beside the date otherwise.
Similarly, setting the variable mark-holidays-in-calendar to
t marks holiday dates, either with a change of face or with an
asterisk (`*').
The variable calendar-holiday-marker specifies how to mark a
date as being a holiday. Its value may be a character to insert next to
the date, or a face name to use for displaying the date. Likewise, the
variable diary-entry-marker specifies how to mark a date that has
diary entries. The calendar creates faces named holiday-face and
diary-face for these purposes; those symbols are the default
values of these variables, when Emacs supports multiple faces on your
terminal.
The variable calendar-load-hook is a normal hook run when the
calendar package is first loaded (before actually starting to display
the calendar).
Starting the calendar runs the normal hook
initial-calendar-window-hook. Recomputation of the calendar
display does not run this hook. But if you leave the calendar with the
q command and reenter it, the hook runs again.
The variable today-visible-calendar-hook is a normal hook run
after the calendar buffer has been prepared with the calendar when the
current date is visible in the window. One use of this hook is to
replace today's date with asterisks; to do that, use the hook function
calendar-star-date.
(add-hook 'today-visible-calendar-hook 'calendar-star-date)
Another standard hook function marks the current date, either by changing its face or by adding an asterisk. Here's how to use it:
(add-hook 'today-visible-calendar-hook 'calendar-mark-today)
The variable calendar-today-marker specifies how to mark today's
date. Its value should be a character to insert next to the date or a
face name to use for displaying the date. A face named
calendar-today-face is provided for this purpose; that symbol is
the default for this variable when Emacs supports multiple faces on your
terminal.
A similar normal hook, today-invisible-calendar-hook is run if
the current date is not visible in the window.
