This repository contains idiomatic C++ client libraries for the following
[Google Cloud Platform](https://cloud.google.com/) services.

> Please refer to the [V3 Migration Guide](/doc/v3-migration-guide.md) for
> details on updating existing applications using v1.x.y or v2.x.y.

> Please check the [CHANGELOG] for important announcements and upcoming changes.

## Quickstart

Each library (see below) contains a directory named `quickstart/` that's
intended to help you get up and running in a matter of minutes. This
`quickstart/` directory contains a minimal "Hello World" program demonstrating
how to use the library, along with minimal build files for common build systems,
such as CMake and Bazel.

As an example, the following code snippet, taken from
[Google Cloud Storage](google/cloud/storage/README.md), should give you a sense
of what it's like to use one of these C++ libraries.

<!-- inject-quickstart-start -->

```cc
#include "google/cloud/storage/client.h"
#include "google/cloud/common_options.h"
#include <cstdlib>
#include <iostream>
#include <string>

int main(int argc, char* argv[]) {
  if (argc != 2) {
    std::cerr << "Missing bucket name.\n";
    std::cerr << "Usage: quickstart <bucket-name>\n";
    return 1;
  }
  std::string const bucket_name = argv[1];

  // Create a client to communicate with Google Cloud Storage. This client
  // uses the default configuration for authentication and project id.
  auto options = google::cloud::Options{};

  // If the CURL_CA_BUNDLE environment variable is set, configure the client
  // to use it. This is required for the Windows CI environment where standard
  // system roots may not be sufficient or accessible by the hermetic build.
  auto const* ca_bundle = std::getenv("CURL_CA_BUNDLE");
  if (ca_bundle != nullptr) {
    options.set<google::cloud::CARootsFilePathOption>(ca_bundle);
  }

  auto client = google::cloud::storage::Client(options);

  auto writer = client.WriteObject(bucket_name, "quickstart.txt");
  writer << "Hello World!";
  writer.Close();
  if (!writer.metadata()) {
    std::cerr << "Error creating object: " << writer.metadata().status()
              << "\n";
    return 1;
  }
  std::cout << "Successfully created object: " << *writer.metadata() << "\n";

  auto reader = client.ReadObject(bucket_name, "quickstart.txt");
  if (!reader) {
    std::cerr << "Error reading object: " << reader.status() << "\n";
    return 1;
  }

  std::string contents{std::istreambuf_iterator<char>{reader}, {}};
  std::cout << contents << "\n";

  return 0;
}
```

## GA Libraries

See each library's `README.md` file for more information about:

- Where to find the documentation for the library and the service.
- How to get started using the library.
- How to incorporate the library into your build system.
- The library's support status if not Generally Available (GA); unless noted in
  a library's `README.md`, these libraries are all GA and supported by Google.

## Building and Installing

This is a quickstart guide for developers wanting to compile the libraries and
run the examples included with the libraries.

- Packaging maintainers or developers who prefer to install the library in a
  fixed directory (such as `/usr/local` or `/opt`) should consult the
  [packaging guide](/doc/packaging.md).
- Developers who prefer using a package manager such as
  [vcpkg](https://vcpkg.io), or [Conda](https://conda.io), should follow the
  instructions for their package manager.
- Developers wanting to use the libraries as part of a larger CMake or Bazel
  project should consult the [quickstart guides](#quickstart) for the library or
  libraries they want to use.
- Developers wanting to compile the library just to run some examples or tests
  should read the current document.
- Contributors and developers to `google-cloud-cpp` should consult the guide to
  [set up a development workstation][howto-setup-dev-workstation].

### Building with Bazel

This library requires Bazel >= 7.0. We recommend using Bazel modules instead of
WORKSPACE files. From the top-level directory, run the usual commands.

```shell
bazel build //...
```

### Building with CMake

This library requires CMake >= 3.22. If you are planning to install the
libraries please consult the [packaging guide](/doc/packaging.md), these
instructions will **NOT** produce artifacts that you can put in `/usr/local`, or
share with your colleagues.

From the top-level directory of `google-cloud-cpp` run these commands:

```shell
git -C $HOME clone https://github.com/microsoft/vcpkg.git
env VCPKG_ROOT=$HOME/vcpkg $HOME/vcpkg/bootstrap-vcpkg.sh
cmake -S . -B cmake-out/ -DCMAKE_TOOLCHAIN_FILE=$HOME/vcpkg/scripts/buildsystems/vcpkg.cmake
cmake --build cmake-out -- -j $(nproc)
```

The binary artifacts, such as examples, will be placed in `cmake-out/`.

## Public API and API Breaking Changes

This project follows Google's [OSS Library Breaking Change Policy].

In general, we avoid making backwards incompatible changes to our
[public API](/doc/public-api.md). Sometimes such changes yield benefits to our
customers, in the form of better performance, easier-to-understand APIs, and/or
more consistent APIs across services. When these benefits warrant it, we will:

- Announce these changes prominently in our `CHANGELOG.md` file and in the
  affected release's notes.
- Increase the major version for `google-cloud-cpp`.

Nevertheless, though we take commercially reasonable efforts to prevent this, it
is possible that backwards incompatible changes go undetected and, therefore,
undocumented. We apologize if this is the case and welcome feedback or bug
reports to rectify the problem.
