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("大化三年弥生三日丑三つ刻");

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. Note that it will try to auto-detect whatever encoding you're using via Encode::Guess, so you should be safe to pass any of UTF-8, euc-jp, shift-jis, and iso-2022-jp encoded strings.

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)

Create a string representation of the year of a DateTime::Calendar::Japanese object in Japanese

$fmt->format_month($dt)

Create a string representation of the month of a DateTime::Calendar::Japanese object in Japanese

$fmt->format_day($dt)

Create a string representation of the day (day of month) of a DateTime::Calendar::Japanese object in Japanese

$fmt->format_time($dt)

Create a string representation of the time (hour, minute, second) of a DateTime::Calendar::Japanese object in Japanese
