Class Method Details

.configure {|::Google::Cloud.configure.translate| ... } ⇒ ::Google::Cloud::Config

Configure the google-cloud-translate library.

The following configuration parameters are supported:

  • credentials (type: String, Hash, Google::Auth::Credentials) - The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object.
  • lib_name (type: String) - The library name as recorded in instrumentation and logging.
  • lib_version (type: String) - The library version as recorded in instrumentation and logging.
  • interceptors (type: Array<GRPC::ClientInterceptor>) - An array of interceptors that are run before calls are executed.
  • timeout (type: Numeric) - Default timeout in seconds.
  • metadata (type: Hash{Symbol=>String}) - Additional headers to be sent with the call.
  • retry_policy (type: Hash) - The retry policy. The value is a hash with the following keys:
    • :initial_delay (type: Numeric) - The initial delay in seconds.
    • :max_delay (type: Numeric) - The max delay in seconds.
    • :multiplier (type: Numeric) - The incremental backoff multiplier.
    • :retry_codes (type: Array<String>) - The error codes that should trigger a retry.

Yields:

Returns:

  • (::Google::Cloud::Config) —

    The default configuration used by this library

.translation_service(version: :v3, transport: :grpc, &block) ⇒ ::Object

Create a new client object for TranslationService.

By default, this returns an instance of Google::Cloud::Translate::V3::TranslationService::Client for a gRPC client for version V3 of the API. However, you can specify a different API version by passing it in the version parameter. If the TranslationService service is supported by that API version, and the corresponding gem is available, the appropriate versioned client will be returned. You can also specify a different transport by passing :rest or :grpc in the transport parameter.

About TranslationService

Provides natural language translation operations.

Parameters:

  • version (::String, ::Symbol) (defaults to: :v3) —

    The API version to connect to. Optional. Defaults to :v3.

  • transport (:grpc, :rest) (defaults to: :grpc) —

    The transport to use. Defaults to :grpc.

Returns:

  • (::Object) —

    A client object for the specified version.

.translation_v2_service(project_id: nil, credentials: nil, key: nil, scope: nil, retries: nil, timeout: nil, endpoint: nil) ⇒ Google::Cloud::Translate::V2::Api

Creates a new object for connecting to the legacy V2 version of the Cloud Translation API.

Like other Cloud Platform services, Google Cloud Translation API supports authentication using a project ID and OAuth 2.0 credentials. In addition, it supports authentication using a public API access key. (If both the API key and the project and OAuth 2.0 credentials are provided, the API key will be used.) Instructions and configuration options are covered in the Authentication Guide.

Examples:

require "google/cloud/translate/v2"

translate = Google::Cloud::Translate::V2.new(
  version: :v2,
  project_id: "my-todo-project",
  credentials: "/path/to/keyfile.json"
)

translation = translate.translate "Hello world!", to: "la"
translation.text #=> "Salve mundi!"

Using API Key.

require "google/cloud/translate/v2"

translate = Google::Cloud::Translate::V2.new(
  key: "api-key-abc123XYZ789"
)

translation = translate.translate "Hello world!", to: "la"
translation.text #=> "Salve mundi!"

Using API Key from the environment variable.

require "google/cloud/translate/v2"

ENV["TRANSLATE_KEY"] = "api-key-abc123XYZ789"

translate = Google::Cloud::Translate::V2.new

translation = translate.translate "Hello world!", to: "la"
translation.text #=> "Salve mundi!"

Parameters:

  • project_id (String) (defaults to: nil) —

    Project identifier for the Cloud Translation service you are connecting to. If not present, the default project for the credentials is used.

  • credentials (String, Hash, Google::Auth::Credentials) (defaults to: nil) —

    The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object.

  • key (String) (defaults to: nil) —

    a public API access key (not an OAuth 2.0 token)

  • scope (String, Array<String>) (defaults to: nil) —

    The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs.

    The default scope is:

    • https://www.googleapis.com/auth/cloud-platform
  • retries (Integer) (defaults to: nil) —

    Number of times to retry requests on server error. The default value is 3. Optional.

  • timeout (Integer) (defaults to: nil) —

    Default timeout to use in requests. Optional.

  • endpoint (String) (defaults to: nil) —

    Override of the endpoint host name. Optional. If the param is nil, uses the default endpoint.

Returns:

  • (Google::Cloud::Translate::V2::Api)
