xcalendar [month [year]]


xcalendar is a simple interactive calendar program with a notebook capability. It is built on the X Toolkit and the Athena or Motif Widgets (compile time option).

If month and year are not provided on the command line they are assumed to be current.


Clicking the left mouse button on a day will start a text editor. You can edit and save a text. This text will be associated with the day. You can later on read and edit this text when you open the editor for the same day. The text is saved in a file in the directory specified by the calendarDir resource (default ~/Calendar). The editor lets you also clear an entry associated with a particular day. You can also scroll through days while in the editor by clicking on the arrows on either side of the date label. If an already open day is scrolled to, an appropriate message is displayed and the editor is brought upin read only mode.

It is also possible to scroll through months in the main window by clicking on the arrows on either side of the current date label.

You can highlight all entries in a month by invoking the function ShowEntries. By default this function is called when the left mouse button is pressed in the title window (where month and a year are displayed). Pressing again the same button will unhighlight the entries.

"Holidays" are shown in a text widget near the bottom of the day editor. Holidays are read from a holiday file (see holidayFile below). The format of the file is mm/dd/yyyy holidaytext where the date and text are separated by a tab. Currently there is no wildcarding done.


One can imagine many useful features. For example automatic parsing of the current day entry in search for appointments to trigger alarms (reminders) at the approriate time. Actually, there is a perl script called xcalendar+ that will do this sort of thing. Maybe one day xcalendar will do it internally.


The resource data base lets you alter the visual appearance of the program. You can change fonts, border widths, labels, and other resources used by widgets. One use of this facility is to change names of week days and months.

Here are the names of widgets you can use to set various resources:

XCalendar    - class of the application

controls     - control panel
quitButton   - quit button

MON,TUE,WED,THU,FRI,SAT,SUN - day name buttons
helpWindow   - help window
bcontrols    - month buttons frame
prev         - previous month button
succ         - succeeding month button
cdate        - current date widget
dayEditor    - editor popup
editorFrame  - editor frame
editorTitle  - editor title
editor       - editor
holiday      - holiday text
daybuttons   - day buttons frame
prevday      - previous day button

                    and False for color displays;

setMarkBackground - if True and reverseVideoMark is False the entries are highlighted by setting background to markBackground ;

markBackground - background color for highlighting entries;

setMarkForeground - analogous to setMarkBackground;

markOnStartup - if True mark the entries upon startup, default: False;

helpFile - full pathname of the xcalendar.hlp file, default: /usr/lib/X11/xcalendar/xcalendar.hlp;

textBufferSize - maximum size of the text buffer in the day editor, default: 2048;

calendarDir - path name of directory to use for storing calendar files instead of keeping them in $HOME/Calendar;

holidayFile - path name of file to use for determining holiday, default: /usr/lib/X11/xcalendar/xcalendar.hol;

oldStyle - uses version 3.0 and prior file naming convention, (xcDAYmonYEAR), where DAY and YEAR are numeric and mon is the first three letters of the month, instead of the "new style" (xcyyyymmdd), default: True;

markCurrent - if True mark the current day (if visible; useful on color displays only), default: False;

updateCurrent - number of seconds between attempts to update the marking of the current day, default: 60;

currentForeground - foreground color for current day highlight;

markHoliday - if True mark holidays (if visible; useful on color displays only), default: False;

holidayForeground - foreground color for holiday highlight;

monthnames - string of ’/’ separated month names used for formatting the date in cdate;

monthnms - string of ’/’ separated month abbreviations used for formatting the date in cdate;

daynames - string of ’/’ separated day names used for formatting the date in cdate;

daynms - string of ’/’ separated day abbreviations used for formatting the date in cdate;

date - format string for date in cdate. The formatting characters that are understood are:

%W Full weekday name %w Three-char weekday name %M Full month name %m Three-char abbreviation for that month %d The date (numerical day number of the month) %Y Full year (4 digits) %y 2-digit year number
