Constants

const Scope = raw.CloudPlatformScope

Scope is the OAuth2 scope required by the Google Cloud Vision API.

Types

type Client

type Client struct {
	// contains filtered or unexported fields
}

Client is a client for the translate API.

func NewClient

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient constructs a new Client that can perform Translation operations.

You can find or create API key for your project from the Credentials page of the Developers Console (console.developers.google.com).

func (*Client) Close

func (c *Client) Close() error

Close closes any resources held by the client. Close should be called when the client is no longer needed. It need not be called at program exit.

func (*Client) DetectLanguage

func (c *Client) DetectLanguage(ctx context.Context, inputs []string) ([][]Detection, error)

DetectLanguage attempts to determine the language of the inputs. Each input string may be in a different language.

Each slice of Detections in the return value corresponds with one input string. A slice of Detections holds multiple hypotheses for the language of a single input string.

func (*Client) SupportedLanguages

func (c *Client) SupportedLanguages(ctx context.Context, target language.Tag) ([]Language, error)

SupportedLanguages returns a list of supported languages for translation. The target parameter is the language to use to return localized, human readable names of supported languages.

func (*Client) Translate

func (c *Client) Translate(ctx context.Context, inputs []string, target language.Tag, opts *Options) ([]Translation, error)

Translate one or more strings of text from a source language to a target language. All inputs must be in the same language.

The target parameter supplies the language to translate to. The supported languages are listed at https://cloud.google.com/translation/v2/translate-reference#supported_languages. You can also call the SupportedLanguages method.

The returned Translations appear in the same order as the inputs.

type Detection

type Detection struct {
	// Language is the code of the language detected.
	Language language.Tag

	// Confidence is a number from 0 to 1, with higher numbers indicating more
	// confidence in the detection.
	Confidence float64

	// IsReliable indicates whether the language detection result is reliable.
	IsReliable bool
}

Detection represents information about a language detected in an input.

type Format

type Format string

The format of the input text. Used in Options.Format.

const (
	HTML Format = "html"
	Text Format = "text"
)

Constants for Options.Format.

type Language

type Language struct {
	// Name is the human-readable name of the language.
	Name string

	// Tag is a standard code for the language.
	Tag language.Tag
}

A Language describes a language supported for translation.

type Options

type Options struct {
	// Source is the language of the input strings. If empty, the service will
	// attempt to identify the source language automatically and return it within
	// the response.
	Source language.Tag

	// Format describes the format of the input texts. The choices are HTML or
	// Text. The default is HTML.
	Format Format

	// The model to use for translation. The choices are "nmt" or "base". The
	// default is "base".
	Model string
}

Options contains options for Translate.

type Translation

type Translation struct {
	// Text is the input text translated into the target language.
	Text string

	// Source is the detected language of the input text, if source was
	// not supplied to Client.Translate. If source was supplied, this field
	// will be empty.
	Source language.Tag

	// Model is the model that was used for translation.
	// It may not match the model provided as an option to Client.Translate.
	Model string
}

A Translation contains the results of translating a piece of text.
