Cloud Translation API C++ Client Library

An idiomatic C++ client library for the Cloud Translation API, a service to integrate text translation into your website or application.

While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.

Quickstart

The following shows the code that you'll run in the google/cloud/translate/quickstart/ directory, which should give you a taste of the Cloud Translation API C++ client library API.

#include "google/cloud/translate/v3/translation_client.h"
#include "google/cloud/project.h"
#include <iostream>

auto constexpr kText = R"""(
Four score and seven years ago our fathers brought forth on this
continent
, a new nation, conceived in Liberty, and dedicated to
the proposition that all men are created equal
.)""";

int main(int argc, char* argv[]) try {
 
if (argc < 2 || argc > 3) {
    std
::cerr << "Usage: " << argv[0] << " project-id "
             
<< "[target-language (default: es-419)]\n";
   
return 1;
 
}

 
namespace translate = ::google::cloud::translate_v3;
 
auto client = translate::TranslationServiceClient(
      translate
::MakeTranslationServiceConnection());

 
auto const project = google::cloud::Project(argv[1]);
 
auto const target = std::string{argc >= 3 ? argv[2] : "es-419"};
 
auto response =
      client
.TranslateText(project.FullName(), target, {std::string{kText}});
 
if (!response) throw std::move(response).status();

 
for (auto const& translation : response->translations()) {
    std
::cout << translation.translated_text() << "\n";
 
}

 
return 0;
} catch (google::cloud::Status const& status) {
  std
::cerr << "google::cloud::Status thrown: " << status << "\n";
 
return 1;
}

Main classes

The main class in this library is translate_v3::TranslationServiceClient. All RPCs are exposed as member functions of this class. Other classes provide helpers, configuration parameters, and infrastructure to mock translate_v3::TranslationServiceClient when testing your application.
