Overview

This package provides a comprehensive set of functions for converting text between different writing systems of the Ainu language.

Currently, Latin (Romanization), Katakana and Cyrillic scripts are supported. We are also planning to convert between different romanization systems and Katakana variants. Currently only the more adopted version of Latin script and lossy Katakana script are supported.

Sentence conversion is planned to be supported in the future. For now, only well-formed single word is accepted. The converted string are always in lower case.

Important Note

Conversion between Latin and Cyrillic script are lossless, however, conversion between Katakana and other scripts are lossy. This means that converting from Katakana to other scripts and then back to Katakana may not give the original string and the result may be ambiguous or even incorrect.

This is because the Katakana script used broadly for the Ainu language is intrinsically ambiguous. For example, it does not distinguish between tow and tu (both トゥ), iw and i.u (both イウ), ay and a.i (both アイ), etc. Some alternative Katakana scripts are proposed to solve this problem, but none of them are widely adopted. We are planning to support some of these alternative scripts in the future.

Installation

    # ...
)

print(kana2latn("イランカラㇷ゚テ")) # "irankarapte"
print(latn2kana("irankarapte")) # "イランカラㇷ゚テ"
print(cyrl2latn("иранкараптэ")) # "irankarapte"
print(latn2cyrl("irankarapte")) # "иранкараптэ"
print(cyrl2kana("иранкараптэ")) # "イランカラㇷ゚テ"
print(kana2cyrl("イランカラㇷ゚テ")) # "иранкараптэ"

Extra Functionality

Conversion Options

Katakana

from ainconv import latn2kana

# Use ヰ (wi), ヱ (we) and ヲ (wo) in conversion
assert latn2kana("wiki") == "ウィキ"  # for loanwords only
assert latn2kana("wiki", use_wi=True) == "ヰキ"
assert latn2kana("wenpe") == "ウェンペ"
assert latn2kana("wenpe", use_we=True) == "ヱンペ"
assert latn2kana("wose") == "ウォセ"
assert latn2kana("wose", use_wo=True) == "ヲセ"

assert latn2kana("wiwewo") == "ウィウェウォ"
assert latn2kana("wiwewo", use_wi=True, use_we=True, use_wo=True) == "ヰヱヲ"

Script Detection

Detect the script of a given string.

from ainconv import detect

print(detect("aynu")) # "Latn"
print(detect("アイヌ")) # "Kana"
print(detect("айну")) # "Cyrl"

Syllable Splitting

from ainconv import separate

print(separate("eyaykosiramsuypa")) # ["e", "yay", "ko", "si", "ram", "suy", "pa"]
