Configure your own language

Each language has its own unique grammar exceptions. You can create your own language.json file in the folder "i18n" and give writtenNumber support for it. I don't think the current scheme and logic cover all the cases, but may be cover some.

The following parameters have been used for the currently available languages:

Language parameters

| Parameter | Type | Description | Examples | |-----------------|---------|----------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | useLongScale | boolean | Indicates if it uses long or short scale. | This differs the meaning of the words billion, trillion and so on. | | baseSeparator | string | Separates the base cardinal numbers. | 29 -> twenty-eight. Spanish uses the connector " y " | | unitSeparator | string | Separates the units from the last base cardinal numbers. | 1234 -> one thousand two hundred and thirty-four | | allSeparator | string | Separates all cardinals, not only the last one. | 1125 -> ألف ومائة وخمسة وعشرون | | base | Object | Base cardinals numbers. Numbers that have unique names and are used to build others. | | | alternativeBase | Object | Alternative versions of base cardinals numbers for usage with specific units. These bases will be treated as an extension for the default base. | "alternativeBase": { "feminine": {"1":"одна","2":"дві"} } | | units | Array | A list of number units (string or Object). Gives support to singular, dual an plural units. Check the Object parameters below. | | | unitExceptions | Object | Sometimes grammar exceptions affect the base cardinal joined to the unit. You can set specific exceptions to any base cardinal number. | Converting 1232000 in Spanish: Without Exception (Wrong): -> uno millón doscientos treinta y dos mil With Exception: -> un millón doscientos treinta y dos mil |

Units parameters

A unit can be:

• A simple string. e.g. "hundred"
• An Object with multiple parameters:

| Unit parameter | Description | e.g. of languages | |------------------------|--------------------------------------------------------------------------------------------------------|-------------------| | singular | One element. | All | | dual | Two elements. | ar | | plural | Two or more elements. (or 3 or more) | All | | few | Between 2 and 4 including. | uk | | useAlternativeBase | Overwrites default base. | uk | | useBaseInstead | Use the base cardinal number instead. | es,hu,pt | | useBaseException | Specify with which unit (1 to 9) you don't want to use the base, and instead use the regular behavior. | es,hu,pt | | avoidPrefixException | Units not using the base cardinal number prefix for unit 1. | id,tr,it | | avoidInNumberPlural | Units not using the plural form with trailing numbers other than 0. | fr | | restrictedPlural | Plural only for 3 to 10. Singular if >= 11. | ar | | useSingularEnding | Use singular form for numbers ending with 1. | uk | | useFewEnding | Use few form for numbers ending with 2, 3 or 4. | uk | | avoidEndingRules | Plural form used instead of useSingularEnding and useFewEnding | uk |

Versioning

Do your changes and submit a PR. If you've write access and want to bump the version, run mversion [major|minor|patch] -m. That'll bump both bower.json and package.json.
