NAME

Date::Biorhythm - a biorhythm calculator

SYNOPSIS

From the command line

  biorhythm --birthday=1994-10-09

Usage

  use Date::Biorhythm;
  my $bio = Date::Biorhythm->new({
    birthday => Date::Calc::Object->new(0, 1970, 1, 1),
    name     => 'Unix',
  });

  my $i = 0;
  my $limit = 365;
  $bio->day(Date::Calc::Object->today);
  while ($i < $limit) {
    print $bio->value('emotional'), "\n";
    $bio->next;
    $i++;
  }

DESCRIPTION

I find biorhythms mildly amusing, but I got tired of visiting http://www.facade.com/biorhythm and having to deal with their web-based form for date entry.

I vaguely remembered there being a Perl module for biorhythm calculation, but I couldn't find it on CPAN. However, further investigation finally led me to BackPAN where I found Date::Biorhythm 1.1 which was written by Terrence Brannon (a long time ago).

Wanting an excuse to try Moose out, I decided to make a new and modernized version of Date::Biorhythm, and this is the result.

BUT WTF IS A BIORHYTHM?

METHODS

meta

This method was added by Moose, and it gives you access to Date::Biorhythm's metaclass. (See Moose for more details.)

new

The constructor. It takes on optional hashref that will accept the following keys: name, birthday, and day.

name

Get or set the name associated with this biorhythm. This will usually be a person's name.

birthday

Get or set the birthday used for this biorhythm.

day

Get or set the current day (which is represented by a Date::Calc::Object).

next

Go forward one day by incrementing $self->day.

prev

Go backward one day by decrementing $self->day.

index

Given a primary cycle (such as 'emotional', 'intellectual', or 'physical'), return how many days we are into the cycle. Note that the first day of the cycle returns 0.

value

Given a primary cycle or secondary cycle, return a value between -1 and 1 that represents the current amplitude in the cycle.
