Yatapp

Welcome to Yata integration Hex package, this package will allow you to easy get your translations from https://www.yatapp.net service.

Installation

Add yatapp to your list of dependencies and to applications in mix.exs:

# mix.exs

def deps do
  [
    {:yatapp, "~> 0.2.6"}
  ]
end

def application do
  [applications: [:yatapp]]
end

Configuration

Package can be used in two ways:

integration through API
websocket integration

API Integration

Add configuration to your config/config.exs:

# config.exs

config :yatapp,
  api_key: System.get_env("YATA_API_KEY"),
  project_id: System.get_env("YATA_PROJECT_ID"),
  locales: ~w(en),
  translations_format: "yml",
  save_to_path: "priv/locales/",
  root: false,
  strip_empty: false,
  enable_websocket: false,
  download_on_start: true

API integration allows you to download all translation using mix task:

$ mix yatapp.download_translations

Websocket Integration

Add configuration to your config/config.exs:

# config.exs

config :yatapp,
  api_key: System.get_env("YATA_API_KEY"),
  project_id: System.get_env("YATA_PROJECT_ID"),
  default_locale: "en",
  locales: ~w(en),
  otp_app: :my_app,
  json_parser: Jason,
  store: Yatapp.Store.ETS,
  download_on_start: true,
  save_to_path: "priv/locales/",
  translations_format: "json",
  translation_file_parser: Jason,
  root: false,
  strip_empty: false,
  enable_websocket: true,
  var_prefix: "%{",
  var_suffix: "}",
  fallback: false

Websocket integration connects to Yata server and stays open. All changes in translations are auto-fetched to the app.

When app connects to the Yata server for the first time it fetches all translation and saves them to the ETS table. Then all actions on translations like create, update and delete are broadcasting information and ETS table is updated.

The values for given locale and key can be fetched using Yatappp.ExI18n module:

# Examples

# en
number: 1
hello_name: "Hello %{name}"

Yatapp.translate("en", "number") #=> 1
Yatapp.translate("en", "hello_name", %{name: "John"}) #=> "Hello John"

Download translation

There are two options to download translations. First, by using mix task:

$ mix yatapp.download_translations

Mix task saves downloaded translations files to the indicated directory in the configuration.

Whenever an application starts, we fetch new translations from Yata. The download_on_start option, which is set to true by default, is responsible for this behavior. If you prefer to fetch translations from local files on start, set download_on_start to false.

Pluralization

Yata Pluralization is useful when you want your application to customize pluralization rules. The base pluralizer is Yatapp.Pluralization.Base which apply rules with three keys: :zero, :one and :other. You can create your own and set it as your default pluralizer (see Yatapp.Pluralization.Example). To set new pluralizer change configuration settings:

# config.exs

config :yatapp,
  pluralizer: Yatapp.Pluralization.Example

The interpolation value :count has a special role it both is interpolated to the translation and used to pick a pluralization form the translations according to the pluralization rules defined in the pluralization backend.

# Examples

# en

messages:
  zero: "no message"
  one: "1 message"
  other: "%{count} messages"

Yatapp.translate("en", "messages", %{count: 0}) #=> "no message"
Yatapp.translate("en", "messages", %{count: 1}) #=> "1 message"
Yatapp.translate("en", "messages", %{count: 2}) #=> "no messages"

Language Plural Rules (CLDR)

Configure http timeouts

Http timeout options:

:timeout - timeout for establishing a TCP or SSL connection, in milliseconds. Default is 8000
:recv_timeout - timeout for receiving an HTTP response from the socket. Default is 5000

# config.exs

config :yatapp,
  http: %{
    timeout: 50_000,
    recv_timeout: 50_000
  }
