NAME
DateTime::Format::Baby - Parse and format baby-style time
SYNOPSIS
use DateTime::Format::Baby;
my $Baby = DateTime::Format::Baby->new('en');
my $dt = $Baby->parse_datetime('The big hand is on the twelve and the little hand is on the six.');
$Baby->language('fr');
print $Baby->format_datetime($dt);
# -> La grande aiguille est sur le douze et la petite aiguille est sur le sixExtended example, with a fancy clockface (seen in Acme::Time::Asparagus).
use DateTime::Format::Baby;
my $baby = DateTime::Format::Baby->new(language => 'en',
numbers => [
'Tomato', 'Eggplant', 'Carrot', 'Garlic',
'Green Onion', 'Pumpkin', 'Asparagus', 'Onion',
'Corn', 'Brussels Sprout', 'Red Pepper', 'Cabbage',
]
);
my $dt = DateTime->new(year => 1964, month => 10, day => 16,
hour => 17, minute => 36, second => 0
);
print $baby->format_datetime($dt);
# -> The big hand is on the Asparagus and the little hand is on the PumpkinDESCRIPTION
This module understands baby talk in a variety of languages.
METHODS
This class offers the following methods.
new($language) or new(%hash)
As usual, this class method returns an instance of the class.
The method can receive either a single parameter specifying the language, or a hash with various parameters (note: not a hash reference, a real hash, in other words a list with an even number of elements). The hash may contain the following keys:
language
Two-char code of a language (ISO 639-1) or special cases "Swedish chef" and "warez".
numbers
Array reference containing the twelve numbers on the clockface. Number "1" is in position 0, number "2" is in position 1, until number "12" which is in position 11.
format
The skeleton of the output baby-talk sentence, with
%sto mark where the values for the big hand and the little hand will be inserted.big
The various names for the big hand, in an array reference. The position within the array does not matter.
little
Same thing for the little hand.
parse_datetime($string)
Given baby talk, this method will return a new
DateTimeobject.For some languages (en, de, es, fr and it) parsing uses a regexp on various synonyms for 'big' and 'little'. For all other languages, the module only understands the same phrase that it would give using format_datetime().
If given baby talk that it can't parse, this method may either die or get confused. Don't try things like "The big and little hands are on the six and five, respectively."
format_datetime($datetime)
Given a
DateTimeobject, this methods returns baby talk. Remember though that babies only understand time (even then, without am/pm)language($language)
When given a language, this method sets its language appropriately.
This method returns the current language. (After processing as above)
languages()
This method return a list of known languages.

KNOWN ISSUES AND BUGS
No known bug, only known issues.
As Abigail said in his module Acme::Time::Baby, the "Baby" part of the module name is a misnomer, because you have to be at least a toddler to read a clockface and describe it in a complete sentence with a correct syntax (even if a simple one). On the other hand, the common phrase is not "toddler talk", but "baby talk". Therefore Acme::Time::Baby keeps its name Acme::Time::Baby and DateTime::Format::Baby keeps its name DateTime::Format::Baby.
Baby talk does not implement years, months, days or even AM/PM. It's more for amusement than anything else.
You may think that a roundtrip like this:
my $string = $baby->format_datetime($datetime);
my $new_datetime = $baby->parse_datetime($string);should give the same value with a 5-minute fuzz factor. This is not the case for two reasons. As stated above, babies (or toddlers) do not understand the AM/PM factor. So there can be a 12-hour skip in the roundtrip. The second reason is that when the time is a few minutes past the half-hour (say xx:31 or xx:32), the small hand is not on the same number as when the time is exactly on the half-hour. So there is a 1-hour jump forward during such a round-trip.
As already said above, baby talk does not include convoluted sentences as: "The big and little hands are on the six and five, respectively" or "Both hands are on the five".
