DESCRIPTION

Note: This package is no longer being maintained by Gregor Mosheh stigmata@blackangel.net. It is recommended that new development be built against HTML::CalendarMonth.

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.

The optional constructor arguments 'year' and 'month' can specify which month's calendar will be used. If either is omitted, the current value (e.g. "today") 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.

The arguments 'today_year', 'today_month', and 'today_date' may also be specified, to specify what "today" is. If not specified, the system clock will be used. This is particularly useful when the todaycolor() et al methods are used, and/or if you're dealing with multiple timezones. Note that these arguments change what "today" is, which means that if you specify a today_year and a today_month then you are effectively specifying a 'year' and 'month' argument as well, though you can also specify a year and month argument and override the "today" behavior.

# Examples:
# Create a calendar for this month.
$cal = new HTML::CalendarMonthSimple();
# A calendar for a specific month/year
$cal = new HTML::CalendarMonthSimple('month'=>2,'year'=>2000);
# Pretend that today is June 10, 2000 and display the "current" calendar
$cal = new HTML::CalendarMonthSimple('today_year'=>2000,'today_month'=>6,'today_date'=>10);

year

month

today_year

today_month

today_date

monthname

These methods simply return the year/month/date of the calendar, as specified in the constructor.

monthname() returns the text name of the month, e.g. "December".

setcontent(DATE,STRING)

addcontent(DATE,STRING)

highlight (@DATE)

Highlights the particular dates given.

$cal->highlight(1,10,22);

getcontent(DATE)

These methods are used to control the content of date cells within the calendar grid. The DATE argument may be a numeric date or it may be a string describing a certain occurrence of a weekday, e.g. "3MONDAY" to represent "the third Monday of the month being worked with", or it may be the plural of a weekday name, e.g. "wednesdays" to represent all occurrences of the given weekday. The weekdays are case-insensitive.

Since plural weekdays (e.g. 'wednesdays') is not a single date, getcontent() will return the content only for the first occurrence of that day within a month.

# 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.
$cal->setcontent(15,"<b>" . $cal->getcontent(15) . "</b>");

# addcontent() does not clobber 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 sentences

# Padded and decimal numbers may be used, as well:
$cal->setcontent(3.14159,'Third of the month');
$cal->addcontent('00003.0000','Still the third');
$cal->getcontent('3'); # Gets the 2 sentences

# The second Sunday of May is some holiday or another...
$cal->addcontent('2sunday','Some Special Day') if ($cal->month() == 5);

# Every Wednesday is special...
$cal->addcontent('wednesdays','Every Wednesday!');

# either of these will return the content for the 1st Friday of the month
$cal->getcontent('1friday');
$cal->getcontent('Fridays'); # you really should use '1friday' for the first Friday

Note: A change in 1.21 is that all content is now stored in a single set of date-indexed buckets. Previously, the content for weekdays, plural weekdays, and numeric dates were stored separately and could be fetched and set independently. This led to buggy behavior, so now a single storage set is used.

# Example:
# if the 9th of the month is the second Wednesday...
$cal->setcontent(9,'ninth');
$cal->addcontent('2wednesday','second wednesday');
$cal->addcontent('wednesdays','every wednesday');
print $cal->getcontent(9);

In version 1.20 and previous, this would print 'ninth' but in 1.21 and later, this will print all three items (since the 9th is not only the 9th but also a Wednesday and the second Wednesday). This could have implications if you use setcontent() on a set of days, since other content may be overwritten:

# Example:
# the second setcontent() effectively overwrites the first one
$cal->setcontent(9,'ninth');
$cal->setcontent('2wednesday','second wednesday');
$cal->setcontent('wednesdays','every wednesday');
print $cal->getcontent(9); # returns 'every wednesday' because that was the last assignment!

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...

weekstartsonmonday([1|0])

By default, calendars are displayed with Sunday as the first day of the week (American style). Most of the world prefers for calendars to start the week on Monday. This method selects which type is used: 1 specifies that the week starts on Monday, 0 specifies that the week starts on Sunday (the default). If no value is given at all, the current value (1 or 0) is returned.

# Example:
$cal->weekstartsonmonday(1); # switch over to weeks starting on Monday
$cal->weekstartsonmonday(0); # switch back to the default, where weeks start on Sunday

# Example:
print "The week starts on " . ($cal->weekstartsonmonday() ? 'Sunday' : 'Monday') . "\n";

Days_in_Month

This function returns the number of days on the current calendar.

foreach my $day (1 .. $cal->Days_in_Month) {
  $cal->setdatehref($day, &make_url($cal->year, $cal->month, $day));
}

setdatehref(DATE,URL_STRING)

getdatehref(DATE)

These allow the date-number in a calendar cell to become a hyperlink to the specified URL. The DATE may be either a numeric date or any of the weekday formats described in setcontent(), et al. If plural weekdays (e.g. 'wednesdays') are used with getdatehref() the URL of the first occurrence of that weekday in the month will be returned (since 'wednesdays' is not a single date).

# Example:
# The date number in the cell for the 15th of the month will be a link
# then we change our mind and delete the link by assigning a null string
$cal->setdatehref(15,"http://sourceforge.net/");
$cal->setdatehref(15,'');

# Example:
# the second Wednesday of the month goes to some website
$cal->setdatehref('2wednesday','http://www.second-wednesday.com/');

# Example:
# every Wednesday goes to a website
# note that this will effectively undo the '2wednesday' assignment we just did!
# if we wanted the second Wednesday to go to that special URL, we should've done that one after this!
$cal->setdatehref('wednesdays','http://every-wednesday.net/');

contentfontsize([STRING])

contentfontsize() sets the font size for the contents of the cell, overriding the browser's default. Can be expressed as an absolute (1 .. 6) or relative (-3 .. +3) size.

border([INTEGER])

This specifies the value of the border attribute to the

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.

cellpadding

cellspacing

width([INTEGER][%])

This sets the value of the width attribute to the

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 size

showdatenumbers([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])

weekdayheadersbig([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 weekdayheadersbig() is set to 1 (the default) then the weekday headers will be in <th> cells. The effect in most web browsers is that they will be boldfaced and centered. If set to 0, the weekday headers will be in <td> cells and in normal text.

For both functions, if no value is specified, the current value is returned.

cellalignment([STRING])

vcellalignment([STRING])

cellalignment() sets the value of the align attribute to the

# 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");

# Example:
$cal->bgcolor('white');                  # Set the default cell bgcolor
$cal->bordercolor('green');              # Set the default border color
$cal->contentcolor('black');             # Set the default content color
$cal->headercolor('yellow');             # Set the bgcolor of the Month+Year header
$cal->headercontentcolor('yellow');      # Set the content color of the Month+Year header
$cal->weekdayheadercolor('orange');      # Set the bgcolor of weekdays' headers
$cal->weekendheadercontentcolor('blue'); # Set the color of weekday headers' contents
$cal->weekendheadercolor('pink');        # Set the bgcolor of weekends' headers
$cal->weekdayheadercontentcolor('blue'); # Set the color of weekend headers' contents
$cal->weekendcolor('palegreen');         # Override weekends' cell bgcolor
$cal->weekendcontentcolor('blue');       # Override weekends' content color
$cal->todaycolor('red');                 # Override today's cell bgcolor
$cal->todaycontentcolor('yellow');       # Override today's content color
print $cal->as_HTML;                     # Print a really ugly calendar!

# Example: a red-letter day!
$cal->datecolor(3,'pink');
$cal->datecontentcolor(3,'red');

# Example:
# Every Tuesday is a Soylent Green day...
# Note that if the 3rd was a Tuesday, this later assignment would override the previous one.
# see the docs for setcontent() et all for more information.
$cal->datecolor('tuesdays','green');
$cal->datecontentcolor('tuesdays','yellow');

# show the days of the week in Spanish
$cal->saturday('Sábado');
$cal->sunday('Domingo');
$cal->weekdays('Lunes','Martes','Miércoles','Jueves','Viernes');

# show the days of the week in German
$cal->saturday('Samstag');
$cal->sunday('Sonntag');
$cal->weekdays('Montag','Dienstag','Mittwoch','Donnerstag','Freitag');
