# Cloud Shell API C++ Client Library

This directory contains an idiomatic C++ client library for the
[Cloud Shell API][cloud-service-docs], a service to allow users to start,
configure, and connect to interactive shell sessions running in the cloud.

While this library is **GA**, please note that the Google Cloud C++ client
libraries do **not** follow [Semantic Versioning](https://semver.org/).

## Quickstart

The [quickstart/](quickstart/README.md) directory contains a minimal environment
to get started using this client library in a larger project. The following
"Hello World" program is used in this quickstart, and should give you a taste of
this library.

For detailed instructions on how to build and install this library, see the
top-level [README](/README.md#building-and-installing).

```cc
#include "google/cloud/shell/v1/cloud_shell_client.h"
#include <iostream>
#include <string>

int main(int argc, char* argv[]) try {
  if (argc != 2) {
    std::cerr << "Usage: " << argv[0] << " user\n";
    return 1;
  }

  namespace shell = ::google::cloud::shell_v1;
  auto client =
      shell::CloudShellServiceClient(shell::MakeCloudShellServiceConnection());

  auto const name = "users/" + std::string{argv[1]} + "/environments/default";
  auto env = client.GetEnvironment(name);
  if (!env) throw std::move(env).status();
  std::cout << env->DebugString() << "\n";

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