NAME

DateTime::Format::Japanese::Traditional - A Japanese DateTime Formatter For Traditional Japanese Calendar

SYNOPSIS

use DateTime::Format::Japanese::Traditional;
my $fmt = DateTime::Format::Japanese::Traditional->new();

# or if you want to set options,
my $fmt = DateTime::Format::Japanese::Traditional->new(
  number_format           => FORMAT_KANJI,
  month_format            => FORMAT_WAREKI_MONTH,
  with_traditional_marker => 1
);

my $str = $fmt->format_datetime($dt);
my $dt  = $fmt->parse_datetime("Ê¿À®£±£¶Ç¯£±·î£²£·Æü¸áÁ°£µ»þ£³£°Ê¬");

DESCRIPTION

This module implements a DateTime::Format module that can read tradtional Japanese date notations and create a DateTime::Calendar::Japanese object, and vice versa.

XXX WARNING WARNING WARNING XXX

Currently DateTime::Format::Japanese only supports Perl 5.7 and up.
This is because I'm ignorant in the ways of making robust regular
expressions in Perls <= 5.6.x with Jcode. If anybody can contribute to
this, I would much appreciate it

XXX WARNING WARNING WARNING XXX

METHODS

new()

This constructor will create a DateTime::Format::Japanese object. You may optionally pass any of the following parameters:

number_format           - how to format numbers (default: FORMAT_KANJI)
month_format            - how to format months (default: FORMAT_NUMERIC_MONTH)
with_traditional_marker - use traditional calendar marker (default: 0)

Please note that all of the above parameters only take effect for formatting, and not parsing. Parsing is done in a way such that it accepts any of the known formats that this module can produce.

$fmt->parse_datetime($string)

This function will parse a traditional Japanese date/time string and convert it to a DateTime::Calendar::Japanese object. If the parsing is unsuccessful it will croak.

This method can be called as a class function as well.

my $dt = DateTime::Format::Japanese::Traditional->parse_datetime($string);
# or
my $fmt = DateTime::Format::Japanese::Traditional->new();
my $fmt->parse_daettime($string);

FORMATTING METHODS

All of the following methods accept a single parameter, a DateTime::Calendar::Japanese object, and return the appropriate string representation.

my $dt  = DateTime->now();
my $fmt = DateTime::Format::Japanese::Traditional->new(...);
my $str = $fmt->format_datetime($dt);

$fmt->format_datetime($dt)

Create a complete string representation of a DateTime::Calendar::Japanese object in Japanese

$fmt->format_ymd($dt)

Create a string representation of year, month, and date of a DateTime object in Japanese

$fmt->format_year($dt)
