Universal Translator is an i18n Translator for Go/Golang using CLDR data + pluralization rules

Why another i18n library?

Because none of the plural rules seem to be correct out there, including the previous implementation of this package, so I took it upon myself to create locales for everyone to use; this package is a thin wrapper around locales in order to store and translate text for use in your applications.

Features

• Rules generated from the CLDR data, v30.0.3
• Contains Cardinal, Ordinal and Range Plural Rules
• Contains Month, Weekday and Timezone translations built in
• Contains Date & Time formatting functions
• Contains Number, Currency, Accounting and Percent formatting functions
• Supports the "Gregorian" calendar only ( my time isn't unlimited, had to draw the line somewhere )
• Support loading translations from files
• Exporting translations to file(s), mainly for getting them professionally translated
• Code Generation for translation files -> Go code.. i.e. after it has been professionally translated
• Tests for all languages, I need help with this, please see here

Installation

go get github.com/go-playground/universal-translator

Help With Tests

To anyone interesting in helping or contributing, I sure could use some help creating tests for each language. Please see issue here for details.
