Bond is a cross-platform framework for working with schematized data. It supports cross-language de/serialization and powerful generic mechanisms for efficiently manipulating data. Bond is broadly used at Microsoft in high scale services.

Description

Bond is an open source, cross-platform framework for working with schematized data. It supports cross-language serialization/deserialization and powerful generic mechanisms for efficiently manipulating data. Bond is broadly used at Microsoft in high scale services.

We are also introducing the Bond Communications framework--known as Bond Comm--which allows for remote process communication. Currently, we are making the C# version of this framework available; the C++ version will be released in the coming weeks. This framework is based on is the successor to an internal framework that is used by several large services inside Microsoft. Bond Comm is undergoing active evolution at this time and so we are marking the initial release as version 0.5. Consult the C# manual for more details on Bond Comm's usage and capabilities.

Bond is published on GitHub at https://github.com/Microsoft/bond/.

For details, see the User's Manuals for C++, C# and Python, and the documentation of the compiler tool and library.

Bond

Bond is an open-source, cross-platform framework for working with schematized data. It supports cross-language serialization/deserialization and powerful generic mechanisms for efficiently manipulating data. Bond is broadly used at Microsoft in high scale services.

Bond is published on GitHub at https://github.com/microsoft/bond/.

For details, see the User's Manuals:

• C++
• C#
• Java
• Python
• Bond-over-gRPC (deprecated: will be removed in May 2022)
• gbc, the Bond compiler/codegen tool
  • See also the compiler library that powers gbc.

Dependencies

Bond C++ library requires some C++11 features (currently limited to those supported by Visual C++ 2015); a C++11 compiler is required. Additionally, to build Bond you will need CMake (3.1+), Haskell Stack (1.5.1+) and Boost (1.61+).

Additionally, Bond requires RapidJSON. The Bond repository has a Git submodules for RapidJSON. It should be cloned with the --recursive flag:

git clone --recursive https://github.com/microsoft/bond.git

If you already have RapidJSON and would like to build against it, add argument -DBOND_FIND_RAPIDJSON=TRUE to the CMake invocation. It will use find_package(RapidJSON). If you do not provide a RapidJSON library, Bond will also install RapidJSON.

Following are specific instructions for building on various platforms.

Linux

Bond must be built with C++11 compiler. We test with Clang (3.8) and GNU C++ (5.4). We recommend Clang as it's faster with template-heavy code like Bond.

Run the following commands to install the minimal set of packages needed to build the core Bond library on Ubuntu 14.04:

sudo apt-get install \
    clang \
    cmake \
    zlib1g-dev \
    libboost-dev \
    libboost-thread-dev

Additionally, you need the Haskell Tool Stack. If your distro isn't shipping a new enough version of it, you may encounter some non-obvious build failures, so we recommend installing the latest Stack outside of package management:

curl -sSL https://get.haskellstack.org/ | sh

In the root bond directory run:

mkdir build
cd build
cmake ..
make
sudo make install

The build directory is just an example. Any directory can be used as the build destination.

To build the Bond Python module and all the C++/Python tests and examples, a few more packages are needed.

sudo apt-get install \
    autoconf \
    build-essential \
    libboost-date-time-dev \
    libboost-python-dev \
    libboost-test-dev \
    libtool \
    python2.7-dev

CMake needs to be re-run with different options. This can be done after building just the core libraries: the build tree will simply be updated with the new options.

cd build # or wherever you ran CMake before

Running the following command in the build directory will build and execute all the tests and examples:

make --jobs 8 check
sudo make install # To install the other libraries just built

(The unit tests are large so you may want to run 4-8 build jobs in parallel, assuming you have enough memory.)

macOS

Install Xcode and then run the following command to install the required packages using Homebrew (http://brew.sh/):

brew install \
    cmake \
    haskell-stack \
    boost \
    boost-python

(boost-python is optional and only needed for Python support.)

Bond can be built on macOS using either standard *nix makefiles or Xcode. In order to generate and build from makefiles, in the root bond directory run:

mkdir build
cd build
cmake ..
make
sudo make install

Alternatively, you can generate Xcode projects by passing the -G Xcode option to cmake:

cmake -G Xcode ..

You can build and run unit tests by building the check target in Xcode or by running make in the build directory:

make --jobs 8 check

Note that if you are using Homebrew's Python, you'll need to build boost-python from source:

brew install --build-from-source boost-python

and tell cmake the location of Homebrew's libpython by setting the PYTHON_LIBRARY variable, e.g.:

cmake .. \
    -DPYTHON_LIBRARY=/usr/local/Cellar/python/2.7.9/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib

Windows

Install the following tools:

• Visual Studio 2015 or 2017
  • VS2017 is required to build C# Bond from source
• .NET Core SDK (https://www.microsoft.com/net/core)
  • Alternative to VS2017 for building C# Bond from source
• CMake (http://www.cmake.org/download/)
• Haskell Stack (https://docs.haskellstack.org/en/stable/install_and_upgrade/#windows)

If you are building on a network behind a proxy, set the environment variable HTTP_PROXY, e.g.:

set HTTP_PROXY=http://your-proxy-name:80

Now you are ready to build the C# version of Bond. Open the solution file cs\cs.sln in Visual Studio and build as usual. The C# unit tests can also be run from within the solution.

To build using the .NET Core SDK:

dotnet restore cs\cs.sln
dotnet msbuild cs\cs.sln

The C++ and Python versions of Bond additionally require:

• Boost 1.61+ (http://www.boost.org/users/download/)
• Python 2.7 (https://www.python.org/downloads/)

You may need to set the environment variables BOOST_ROOT and BOOST_LIBRARYDIR to specify where Boost and its pre-built libraries for your environment (MSVC 12 or MSVC 14) can be found, e.g.:

set BOOST_ROOT=D:\boost_1_61_0
set BOOST_LIBRARYDIR=D:\boost_1_61_0\lib64-msvc-14.0

The core Bond library and most examples only require Boost headers. The pre-built libraries are only needed for unit tests, and Python. If Boost or Python libraries are not found on the system, then some tests and examples will not be built.

To generate a solution to build the Bond Core C++ and Python with Visual Studio 2015 run the following commands from the root bond directory:

mkdir build
cd build
set PreferredToolArchitecture=x64
cmake -G "Visual Studio 14 2015 Win64" ..

Setting PreferredToolArchitecture=x64 selects the 64-bit toolchain which dramatically improves build speed. (The Bond unit tests are too big to build with 32-bit tools.)

Instead of cmake you can also use cmake-gui and specify configuration settings in the UI. This configuration step has to be performed only once. From then on you can use the generated solution build\bond.sln from Visual Studio or build from the command line using cmake:

cmake --build . --target
cmake --build . --target INSTALL

To build and execute the unit tests and examples run:

cmake --build . --target check -- /maxcpucount:8

Alternatively, you can build and install Bond using the vcpkg dependency manager:

git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.bat
./vcpkg integrate install
./vcpkg install bond

The Bond port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request in the vcpkg repository.
