transliterate.base module

class transliterate.base.TranslitLanguagePack[source]

Bases: object

Base language pack.

The attributes below shall be defined in every language pack.

language_code: Language code (obligatory). Example value: ‘hy’, ‘ru’. language_name: Language name (obligatory). Example value: ‘Armenian’,

‘Russian’.

character_ranges: Character ranges that are specific to the language.

When making a pack, check this page for the ranges.

mapping: Mapping (obligatory). A tuple, consisting of two strings

(source and target). Example value: (u’abc’, u’աբց’).

reversed_specific_mapping: Specific mapping (one direction only) used

when transliterating from target script to source script (reversed transliteration).

՝՝pre_processor_mapping՝՝: Pre processor mapping (optional). A dictionary

mapping for letters that can’t be represented by a single latin letter.

՝՝reversed_specific_pre_processor_mapping՝՝: Pre processor mapping (

optional). A dictionary mapping for letters that can’t be represented by a single latin letter (reversed transliteration).

example:

>>>    class ArmenianLanguagePack(TranslitLanguagePack):
>>>    language_code = "hy"
>>>    language_name = "Armenian"
