Text::Shinobi - 忍びいろは (Ninja Alphabet) encoding
use Text::Shinobi qw/shinobi/;
print shinobi('しのび'); # => 𨊂浾⽕紫゙
"Shinobi Iroha" is a method to encrypt message that Ninja used. This substitution cipher maps Japanese Kana characters to Kanji.
Text::Shinobi encoding table is based on 萬川集海 the Ninja technique encyclopedia; compiled in 1676. The exact character table has not been revealed in the book (as strictly confidential). This module adopted table "generally known" in current Ninjalogy.
Text::Shinobi->encode('あいう！'); # 𣘸栬𡋽！
Returns encrypted input text (unicode string). Only Hiragana and Katakana are converts, other characters are left.
By default, encode() select a Kanji character following rules:
- use single character if same shape unicode exists.
- viewable in major browser version. (device fonts supported)
So this module's default might change in the future.
You can change encode option by $Text::Shinobi::ENCODE class variable with below constants.
# DUO: double character only
local $Text::Shinobi::ENCODE = Text::Shinobi::DUO;
Text::Shinobi->encode('あいう'); # => ⽊黒⽊⾊⼟⾚
# UTF8MB3: exclude 4 bytes code as utf-8
local $Text::Shinobi::ENCODE = Text::Shinobi::UTF8MB3;
Text::Shinobi->encode('あいう'); # => ⽊黒栬⼟⾚
Text::Shinobi->decode('𣘸栬𡋽？'); # あいう？
Returns text to try decode input text (unicode string).
No exports by default.
use Text::Shinobi qw/shinobi/;
shinobi('...');
Shortcut to Text::Shinobi->encode(...).
Romaji to shinobi iroha: use Lingua::JA::Kana;
use Lingua::JA::Kana;
