$cal->width('50%');
$cal->border(10);
$cal->header('Text at the top of the Grid');

$cal->setdatehref(14, 'http://www.lovers.com/');
$cal->addcontent(14,"<p>Don't forget to buy flowers.");
$cal->addcontent(13,"Thirteenth day of the month");
$cal->bgcolor('pink');
print $cal->as_HTML;DESCRIPTION
HTML::CalendarMonthSimple is a Perl module for generating, manipulating, and printing a HTML calendar grid for a specified month. It is intended as a faster and easier-to-use alternative to HTML::CalendarMonth.
This module requires the Date::Calc module, which is available from CPAN if you don't already have it.
INTERFACE METHODS
new(ARGUMENTS)
Naturally, new() returns a newly constructed calendar object. Recognized arguments are 'year' and 'month', to specify which month's calendar will be used. If either is omitted, the current value is used. An important note is that the month and the year are NOT the standard C or Perl -- use a month in the range 1-12 and a real year, e.g. 2001.
# Examples:
# Create a calendar for this month.
$cal = new HTML::CalendarMonthSimple();
# One for a specific month/year
$cal = new HTML::CalendarMonthSimple('month'=>2,'year=>2000);
# One for "the current date" in 1997
$cal = new HTML::CalendarMonthSimple('year'=>1997);setcontent(DATE,STRING)
addcontent(DATE,STRING)
getcontent(DATE)
These methods are used to control the content of date cells within the calendar grid.
# Examples:
# The cell for the 15th of the month will now say something.
$cal->setcontent(15,"An Important Event!");
# Later down the program, we want the content to be boldfaced.
$foo = "<b>" . $cal->getcontent(15) . "</b>";
$cal->setcontent(15,$foo);
# Or we could get extra spiffy:
$cal->setcontent(15,"<b>" . $cal->getcontent(15) . "</b>");
# Example:
# addcontent() does not clober existing content.
# Also, if you setcontent() to '', you've deleted the content.
$cal->setcontent(16,'');
$cal->addcontent(16,"<p>Hello World</p>");
$cal->addcontent(16,"<p>Hello Again</p>");
print $cal->getcontent(16); # Prints 2 sentencessetdatehref(DATE,URL_STRING)
getdatehref(DATE)
These methods are used to control the content of date cells within the calendar grid.
# Example:
# The date number in the cell for the 15th of the month will
# be a link to the sourceforge website
$cal->setdatehref(15,"http://sourceforge.net/");
# Example:
# You want to add to an URL
$cal->setdatehref(15, $getdatehref(15)."projects/perl/");as_HTML()
This method returns a string containing the HTML table for the month.
# Example:
print $cal->as_HTML();It's okay to continue modifying the calendar after calling as_HTML(). My guess is that you'd want to call as_HTML() again to print the further-modified calendar, but that's your business...
year()
month()
monthname()
These methods simply return the year/month of the calendar. monthname() returns the text name of the month, e.g. "December".
border([INTEGER])
This specifies the value of the border attribute to the <TABLE> declaration for the calendar. As such, this controls the thickness of the border around the calendar table. The default value is 5.
If a value is not specified, the current value is returned. If a value is specified, the border value is changed and the new value is returned.
width([INTEGER][%])
This sets the value of the width attribute to the <TABLE> declaration for the calendar. As such, this controls the horizintal width of the calendar.
The width value can be either an integer (e.g. 600) or a percentage string (e.g. "80%"). Most web browsers take an integer to be the table's width in pixels and a percentage to be the table width relative to the screen's width. The default width is "100%".
If a value is not specified, the current value is returned. If a value is specified, the border value is changed and the new value is returned.
# Examples:
$cal->width(600); # absolute pixel width
$cal->width("100%"); # percentage of screen sizeshowdatenumbers([1 or 0])
If showdatenumbers() is set to 1, then the as_HTML() method will put date labels in each cell (e.g. a 1 on the 1st, a 2 on the 2nd, etc.) If set to 0, then the date labels will not be printed. The default is 1.
If no value is specified, the current value is returned.
The date numbers are shown in boldface, normal size font. If you want to change this, consider setting showdatenumbers() to 0 and using setcontent()/addcontent() instead.
showweekdayheaders([1 or 0])
If showweekdayheaders() is set to 1 (the default) then calendars rendered via as_HTML() will display the names of the days of the week. If set to 0, the days' names will not be displayed.
If no value is specified, the current value is returned.
cellalignment([STRING])
This sets the value of the align attribute to the <TD> tag for each day's cell. This controls how text will be centered/aligned within the cells.
Any value can be used, if you think the web browser will find it interesting. Some useful alignments are: left, right, center, top, and bottom,
By default, cells are aligned to the left.
header([STRING])
By default, the current month and year are displayed at the top of the calendar grid. This is called the "header".
The header() method allows you to set the header to whatever you like. If no new header is specified, the current header is returned.
If the header is set to an empty string, then no header will be printed at all. (No, you won't be stuck with a big empty cell!)
# Example:
# Set the month/year header to something snazzy.
my($y,$m) = ( $cal->year() , $cal->monthname() );
$cal->header("<center><font size=+2 color=red>$m $y</font></center>\n\n");bgcolor([STRING])
weekdaycolor([STRING])
weekendcolor([STRING])
weekdayheadercolor([STRING])
headercolor([STRING])
These define the colors of the cells. If a string (which should be a HTML color-code like '#000000' or a color-word like 'yellow') is supplied as an argument, then the color is set to that specified. Otherwise, the current value is returned. To un-set a value, try assigning the null string as a value.
The bgcolor defines the color of all cells. The weekdaycolor overrides the bgcolor for weekdays (Monday thru\ough Friday), and the weekendcolor overrides the bgcolor for weekend days (Saturday and Sunday). The weekdayheadercolor overrides the bgcolor for the weekday headers that appear at the top of the calendar if showweekdayheaders() is true. The headercolor overrides the bgcolor for the month/year header at the top of the calendar.
# Example:
# This sets a default cell color, and then overrides the cell colors.
# Only the weekday headers aren't overridden, so only they will show
# the default bgcolor of green.
# P.S. I don't recommend this color scheme for production use. ;)
$cal->bgcolor('green');
$cal->weekdaycolor('orange');
$cal->weekendcolor('blue');
#$cal->weekdayheadercolor('silver');
$cal->headercolor('yellow');BUGS, TODO, CHANGES
It would be nice if the week didn't have to start on Sunday. It would also be cool if the weekday headers could be changed (Lunes, Martes, Miercoles,...) or suppressed. It'd be nice if the month could be translated, as well. These features will probably make in into the next version some time in April 2001. If anyone wants to take on any of this work, please feel invited.
Changes in 1.01: Added VALIGN to cells, to make alignment work with browsers better. Added showweekdayheaders(). Corrected a bug that results in the month not fitting on the grid (e.g. March 2003). Added getdatehref() and setdatehref(). Corrected a bug that causes a blank week to be printed at the beginning of some months.
Changes in 1.02: Added the color methods.

This would have been extremely difficult if not for Date::Calc. Many thanks to Steffen Beyer <sb@engelschall.com> for a very fine set of date-related functions!
