NAME
ical - An X based Calendar Program
SYNOPSIS
Ical provides an X interface for maintaining a calendar. A calendar is
basically just a set of items. An item is either an appointment, or a
notice. An appointment starts at a particular time of the day, and
finishes at a particular time of the day. A notice does not have any
starting or ending time. Notices are useful for marking certain days as
special. For example, a calendar may contain a notice for April 15th
indicating that taxes are due. When the documentation below refers to
an item, it applies both to notices and appointments. The main
features of ical are:
* Items can be created and edited easily.
* Items can be cut, copied and pasted.
* Items can be made to repeat in various ways.
* Ical will generate alarms for upcoming appointments.
* Users can view many calendars at a time.
* Calendars can be shared by many users.
* Related items can be grouped in their own calendar.
INVOCATION
You can specify various command line options to control ical.

WINDOWS
The main calendar window displays the appointments and notices for a
particular date.
Date Selector
The top left portion of the window contains a date
selector. You can click on the various arrows to change
the month or the year. The day of the month can be
selected by clicking on the appropriate day in the month
display. The date selector contains various other
buttons for convenient date selection.
Notice Window
The bottom left portion of the window contains the
notices for the selected date. A scroll bar is provided
if all of the notices for the selected date do not fit
into the notice window.
Appointment Window
The right portion of the window contains the appointments
for the selected day. You can scroll this region by using
the scroll bar, or by dragging with the middle mouse
button in the background.
Menubar
A menubar runs along the top of the calendar window. The
File menu allows you to create and destroy application
windows.
Status Line
The bottom portion of the window contains a status line.
This status line indicates the calendar from which the
selected item comes and whether or not the selected item
repeats.
CALENDAR FILES
A calendar is stored in a calendar file. The default calendar file is
named .calendar and is kept in the user's home directory. If the
CALENDAR environment variable is set, its value is used as the name of
the calendar file. The CALENDAR environment variable and the default
can both be overridden by specifying a file name on the command line as
follows -- ical -calendar file-name. Ical periodically saves any
modifications made to a calendar to the corresponding calendar file. It
also periodically incorporates changes made to a shared calendar file
by other instances of ical. You can explicitly trigger these periodic
saves and reads by using the File menu.
Including and Sharing Calendars
You can include other calendars into your private calendar. This
facility is mainly useful for allowing a group of people to share a
common set of items. For example, members of a particular group might
have a calendar that contains the birthdays for each member of the
group. This calendar can be included in each group member's private
calendar. Use the File menu to include and exclude shared calendars.
Use the Move Item To ... entry from the Item menu to move items between
calendars. Use the From Calendar ... entry in the List menu to list
all items a particular calendar.
ITEMS
Notices
You can enter notices by clicking in the background in the bottom-left
portion of the main calendar window. This click will create a new
notice for the selected date. You can enter text into the notice by
typing into it while it is selected (selected notices are highlighted
by being displayed in different colors). A notice can be selected for
editing by clicking with left button.
Appointments
You can enter appointments by left-clicking in the background in the
right portion of the main calendar window. This click will create a new
appointment for the selected date. The start time for this appointment
is determined by the click location. You can move the appointment by
dragging it with the middle mouse button held down. The appointment can
be resized by dragging with the right mouse button held down.
Appointment text can be edited by typing into the appointment window
while it is selected. If the appointment text you are typing in does
not fit into the appointment area, then it will overflow out of the
appointment area, but will be editable normally. If you do not like
overflowing text, you should turn off the Allow Text Overflow option in
the Options menu . With this option turned off, if the current text
completely fills the area allocated to the appointment, then any
attempts to add to the appointment text will be ignored until the
appointment is enlarged with the right mouse button. Likewise, the
right mouse button will refuse to shrink an appointment window if the
appointment text completely fills the appointment window.
Alarms
Ical generates alarms for appointments. By default, the first alarm is
generated fifteen minutes before the appointment is supposed to start
and successive alarms are generated every five minutes until the
appointment actually starts. You can change this default behavior by
selecting the Default Alarms entry from the Options menu. You can also
change the timings of these alarms on an appointment-by-appointment
basis by double-clicking on the appointment, or by selecting the
appointment and then chosing the Properties entry in the Item menu.
Repeating Items
Items can be made to repeat in various ways. Item repetition can be
controlled by using the entries in the Repeat menu. These entries make
the item repeat in certain frequently used ways. For example, the
Monthly entry makes the selected item repeat once per month and the
Weekly entry makes the selected item repeat once per week. The Edit
Monthly... and Edit Weekly... entries can be used to make items that
repeat in more complex ways: for example, an item that occurs on the
last Friday of each month, or an item that occurs on Monday, Wednesday,
and Friday every week.
In addition to making an item repeat in one of the pre-defined ways,
you can also restrict an item's starting and finishing date by
selecting the Set Range... entry from the Repeat menu.
Normally, a modification to a repeating item applies to all occurrences
of that item. A single occurrence of a repeating item can be modified
by selecting the occurrence and then choosing the Make Unique entry
from the Repeat menu. The selected occurrence can now be modified
independently of the repeating item.
Todo Items
Items can be marked as todo items by selecting the Todo entry in the
Item menu. A todo item is automatically moved forward to today's date
every day until the item is deleted or marked as done. An item can be
marked as done by clicking in the little check-box right next to the
displayed item.
Highlighting
By default, if any item occurs on a date, then the date is highlighted
in the date selector located in the top-left corner of the calendar
window. You can use the Highlight entries in the Item menu to control
this highlighting behavior on an item-by-item basis.
KEY BINDINGS
This section is currently incomplete.
EDITING
Dragging with the left mouse button in a selected appointment or notice
sets the X selection. The Edit menu provides commands for dealing with
the X selection.
Ical also has a clipboard that can store a single item. The Copy entry
in the Edit menu copies the selected item into the clipboard. The Cut
entry does the same, but it also deletes the item from the calendar. If
the selected item repeats, then the Cut command allows the user to
delete all occurrences of the item, or just the selected occurrence.
However, if the selected item does not belong to you, then Cut just
hides the item from you. Other people will still see the item. An
item in the clipboard can be inserted into the current day by selecting
Paste entry. The newly pasted item loses all repetition information,
and occurs just on the day in which it was pasted.
LISTING ITEMS
You can generate listings of imminent items by selecting one of the
listing options in the List menu. You can also use the command line
options -list, -show, or -popup to generate item listings. The command
line options are most useful in .login files.
By default an item is included in a listing for a particular date if it
occurs either on that date, or on the very next day. You can control
this feature of item listings with the List item entry in the Item
menu.
PRINTING
Calendar contents can be printed by selecting the Print option from the
File menu.
CUSTOMIZATION
Some of ical's behavior can be customized via the Options menu. Other
aspects of ical's behavior can be controlled via X Resources.
X Resources
Behavior
The following X resources can be used to control various aspects of
ical's behavior.
Ical.pollSeconds
Shared calendars are checked for changes made by other
people once every pollSeconds seconds. The default value
is 120. If ical appears sluggish, or if it is using too
much CPU time, increase this value.
Ical.saveSeconds
Calendar files are saved once every saveSeconds seconds.
The default value is 30. If ical appears sluggish, or if
it is using too much CPU time, increase this value.
Dimensions
The following X resources can be used to control various dimensions of
ical's appearance.
Ical.itemSelectWidth
The border width of selected items is set to the value of
this option to display the selected status of the item to
to the user. On color displays, the default value of
this option is 1 because on color displays selection is
indicated by changing the color of the selected item. On
monochrome displays, the default value of itemSelectWidth
is 4.
Ical.Dayview.geometry
X geometry specification for main calendar window.
Usually, you will just specify the window position here.
The size of the window is easier to control via the
Options menu.
Ical.Reminder.geometry
X geometry specification for alarms. Usually, you will
just specify the window position here. The window size
will be calculated automatically.
Ical.Listing.geometry
X geometry specification for item listings. Usually, you
will just specify the window position here. The window
size will be calculated automatically.
Colors
The following X resources can be used to customize ical's use of
colors. If ical windows show up with illegible colors (not enough
distinction between background and foreground), it may be because your
X resources contain definitions for *foreground or *background that
conflict with ical colors. In general, it is a bad idea to define
*foreground and *background in your resources because it will break a
number of programs. You will be better off defining resources on an
application by application basis.
Ical*Foreground/Ical*Background
Foreground and background colors for most of ical's
windows.
Ical*disabledForeground
Foreground color assigned to disabled buttons and menu
entries.
Ical.itemFg/Ical.itemBg
Foreground and background colors for unselected items.
The default foreground is black and the default
background is gray.
Ical.itemSelectFg/Ical.itemSelectBg
Foreground and background colors for selected items. The
default foreground is black and the default background is
SlateBlue1.
Ical.itemOverflowColor/Ical.itemOverflowStipple
Background color and stippling used for appointment text
that overflows out of the appointment area. On color
displays, the default overflow background is SlateBlue3
and no stippling is done (specified by an empty stipple
option). On monochrome displays, the default overflow
background is black, and the default overflow stippling
is gray50.
Ical.apptLineColor
The color for the background lines and times displayed in
the appointment window.
Ical.weekdayColor
The color used to display days of the week. The default
is black.
Ical.weekendColor
The color used to display weekends. The default is red.
Ical.interestColor
The color used to highlight interesting dates. The
default is blue.
Ical.weekendInterestColor
The color used to highlight interesting dates on weekends
and holidays. The default is purple.
Fonts
The following resources can be used to customize ical's use of fonts.
Ical.fontFamily
Preferred font family. Fonts for various purposes are
obtained from this family unless overridden with one of
the specifications below. The default font family is
times. Some other font families you can specify here are
charter, new century schoolbook, and helvetica. My
personal favorite is new century schoolbook.
Ical.fixedFontFamily
Preferred font family for fixed-width fonts. Fixed-width
fonts for various purposes are obtained from this family
unless overridden with one of the specifications below.
The default font family is courier. Some other font
families you can specify here are fixed and terminal.
Ical.fontSize
Font sizes used for ical. Use the value small to use
small font sizes everywhere. Any other value for this
option defaults to the normal fonts.
Ical*itemFont
Font used to display item contents.
Ical.weekdayFont
Font used for displaying days of the week.
Ical.weekendFont
Font used for displaying weekends.
Ical.interestFont
Font used to highlight interesting dates.
Ical.weekendInterestFont
Font used to highlight interesting dates on weekends and
holidays.
Ical.smallHeadingFont
Font used for small headings.
Ical.largeHeadingFont
Font used for large headings.
Ical*<class>*font:
Font used for windows of a certain class. Possible
values for <class> are Dialog, Button, Label, Menubutton,
Menu, Listbox, and Reminder.
Tcl Code
Users can also customize ical by writing tcl code and storing it in the
file ~/.tk/ical/user.tcl. The code stored in this file is executed
when ical starts up.
Ical also looks for site-specific customizations at startup. These
customizations can be placed in the file site.tcl in either the ical
library directory, or its parent directory. (By default, ical looks
for site.tcl in /usr/local/lib/ical/v[version]/, and
/usr/local/lib/ical/, but these directories may be located elsewhere on
your system.) The site specific files will be loaded in before any
user specific customization file is loaded in.
See the "Tcl Interface to Ical" document available via the Ical help
menu.
Ical can run even when X is not available, therefore customization
files should be written so that they will function even when Tk
commands are not available.
MENUS
File Menu
Save Save any modifications to the appropriate calendar files.
Re-Read
Read any changes made to a shared calendar by another
user or another instance of ical. Ical will
automatically invoke this function periodically. It is
provided as a menu entry only so for people who do not
want to wait for ical's periodic checks.
Print Print calendar contents. The user has the option of
saving the print-out to a file, pre viewing the print-out
by specifying a PostScript displaying program, or sending
the print-out directly to a PostScript printer by
specifying a printing command.
Include Calendar
Select a calendar to include into your private calendar.
Included calendars are normally used to share calendars
between different users.
Remove Include
Remove a previously included calendar from your private
calendar.
New Window
Open a new calendar window. This new window can be used
to view the items for a different date than the original
window.
Close Window
Close the selected window.
Exit Save any changes and kill ical.
Edit Menu

calendar. The date and time of this new item are parsed
from the X selection if possible.
Item Menu
Todo Toggle the item between being a todo item and not being a
todo item.
Always Highlight
The item always causes the corresponding date to be
highlighted. This is the default behavior.

The item never causes the corresponding date to be
highlighted.
Highlight Future
The item causes the corresponding date to be highlighted
if and only if the date is not in the past.

Change Alarms
This item pops up a dialog box that allows you to edit
the alarm times for an appointment.
Note that this will only change the alarm times for the selected
appointments. You can make this change for all appointments
that do not have special alarm times by using the Default Alarms
entry in the Options menu.
Early Warning
By default an item is included in a listing for a
particular date if it occurs either on that date, or on
the very next day. Sometimes, you may want to include an
item in listings for earlier dates. For example, if you
have an item reminding you of a birthday on March 17th,
you might want this item to be included in all listings
from March 7th to March 17th so that you will have enough
time to go out and buy a present. You can achieve this
effect by selecting this menu entry and then entering "10
days" into the resulting dialog.
Note that this will only change the listing behavior for the
selected item. You can make this change for all items you
create from now on by using the Default Listings entry in the
Options menu.

start on a Sunday.
Default Alarms
Use this menu entry to change the time intervals at which
alarms go off. The factory settings cause alarms to be
triggered fifteen minutes before each appointment, and
then once every five minutes until the appointment
actually starts. This menu entry changes the default
alarm behavior for all appointments. You can override
this default behavior on an appointment-by-appointment
basis by selecting an appointment and then selecting the
