Calendar::Simple(3pm) User Contributed Perl Documentation Calendar::Simple(3pm)NAME
Calendar::Simple - Perl extension to create simple calendars
SYNOPSIS
use Calendar::Simple;
my @curr = calendar; # get current month
my @this_sept = calendar(9); # get 9th month of current year
my @sept_2002 = calendar(9, 2002); # get 9th month of 2002
my @monday = calendar(9, 2002, 1); # get 9th month of 2002,
# weeks start on Monday
my @span = date_span(mon => 10, # returns span of dates
year => 2006,
begin => 15,
end => 28);
DESCRIPTION
A very simple module that exports one function called "calendar".
calendar
This function returns a data structure representing the dates in a month. The data structure returned is an array of array references. The
first level array represents the weeks in the month. The second level array contains the actual days. By default, each week starts on a
Sunday and the value in the array is the date of that day. Any days at the beginning of the first week or the end of the last week that are
from the previous or next month have the value "undef".
If the month or year parameters are omitted then the current month or year are assumed.
A third, optional parameter, start_day, allows you to set the day each week starts with, with the same values as localtime sets for wday
(namely, 0 for Sunday, 1 for Monday and so on).
date_span
This function returns a cur-down version of a month data structure which begins and ends on dates other than the first and last dates of
the month. Any weeks that fall completely outside of the date range are removed from the structure and any days within the remaining weeks
that fall outside of the date range are set to "undef".
As there are a number of parameters to this function, they are passed using a named parameter interface. The parameters are as follows:
year
The required year. Defaults to the current year if omitted.
mon The required month. Defaults to the current month if omitted.
begin
The first day of the required span. Defaults to the first if omitted.
end The last day of the required span. Defaults to the last day of the month if omitted.
start_day
Indicates the day of the week that each week starts with. This takes the same values as the optional third parameter to "calendar". The
default is 0 (for Sunday).
This function isn't exported by default, so in order to use it in your program you need to use the module like this:
use Calendar::Simple 'date_span';
EXAMPLE
A simple "cal" replacement would therefore look like this:
#!/usr/bin/perl -w
use strict;
use Calendar::Simple;
my @months = qw(January February March April May June July August
September October November December);
my $mon = shift || (localtime)[4] + 1;
my $yr = shift || (localtime)[5] + 1900;
my @month = calendar($mon, $yr);
print "
$months[$mon -1] $yr
";
print "Su Mo Tu We Th Fr Sa
";
foreach (@month) {
print map { $_ ? sprintf "%2d ", $_ : ' ' } @$_;
print "
";
}
A version of this example, called "pcal", is installed when you install this module.
Date Range
This module will make use of DateTime.pm if it is installed. By using DateTime.pm it can use any date that DateTime can represent. If
DateTime is not installed it uses Perl's built-in date handling and therefore can't deal with dates before 1970 and it will also have
problems with dates after 2038 on a 32-bit machine.
