**Crystal I18n** is an internationalization library for the Crystal programming language. It provides a unified interface 

allowing to leverage translations and localized contents in a Crystal project.

Features:

* Translation lookups

* Localization

* Interpolation

* Pluralization rules

* Locale fallbacks

* Flexible configuration

## Documentation

Online browsable documentation is available at https://crystal-i18n.github.io/.

## Installation

Simply add the following entry to your project's `shard.yml`:

```yaml

dependencies:

  i18n:

    github: crystal-i18n/i18n

```

And run `shards install` afterwards.

## Usage

Assuming that a `config/locales` relative folder exists in your project, with the following `en.yml` file in it:

```yaml

en:

  simple:

    translation: "This is a simple translation"

    interpolation: "Hello, %{name}!"

    pluralization:

      one: "One item"

      other: "%{count} items"

```

The following setup could be performed in order to initialize `I18n` properly:

```crystal

require "i18n"

I18n.config.loaders << I18n::Loader::YAML.new("config/locales")

I18n.config.default_locale = :en

I18n.init

```

Here a translation loader is configured to load the previous translation file while also configuring the default locale 

(`en`) and initializing the `I18n` module.

Translations lookups can now be performed using the `#translate` method (or the shorter version `#t`) as follows:

```crystal

I18n.t("simple.translation")                     # outputs "This is a simple translation"

I18n.t("simple.interpolation", name: "John Doe") # outputs "Hello, John Doe!"

I18n.t("simple.pluralization", count: 42)        # outputs "42 items"

```

Please head over to the [documentation](https://crystal-i18n.github.io/) for a more complete overview of the `I18n` 

module capabilities (including the configuration options, localization features, etc).

## Credits

Crystal I18n initially draws its inspiration from [Ruby I18n](https://github.com/ruby-i18n/i18n) and 

[rails-i18n](https://github.com/svenfuchs/rails-i18n). Originally, pluralization and localization rules all come from

[rails-i18n](https://github.com/svenfuchs/rails-i18n) as well.
