android: Add build targets librxcpp and librxcpp-tests am: 122c10b47a am: a81f29220e Change-Id: Ie04b861d7eb2f67e80b6fa3339ac95b8527ed9c1
The Reactive Extensions for C++ (RxCpp) is a library of algorithms for values-distributed-in-time. The Range-v3 library does the same for values-distributed-in-space.

The ReactiveX Observable model allows you to treat streams of asynchronous events with the same sort of simple, composable operations that you use for collections of data items like arrays. It frees you from tangled webs of callbacks, and thereby makes your code more readable and less prone to bugs.

RxCpp uses a git submodule (in ext/catch) for the excellent Catch library. The easiest way to ensure that the submodules are included in the clone is to add --recursive in the clone command.
git clone --recursive https://github.com/Reactive-Extensions/RxCpp.git cd RxCpp
RxCpp uses CMake to create build files for several platforms and IDE's
mkdir projects/build cd projects/build cmake -G"Xcode" ../CMake -B.
mkdir projects\build cd projects\build cmake -G"Visual Studio 14" ..\CMake -B. msbuild rxcpp.sln
mkdir projects/build cd projects/build cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=RelWithDebInfo -B. ../CMake make
mkdir projects/build cd projects/build cmake -G"Unix Makefiles" -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=RelWithDebInfo -B. ../CMake make
mkdir projects/build cd projects/build cmake -G"Unix Makefiles" -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_BUILD_TYPE=RelWithDebInfo -B. ../CMake make
mkdir projects\build cd projects\build cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=RelWithDebInfo -B. ..\CMake nmake
The build only produces test and example binaries.

RxCpp uses Doxygen to generate project documentation.
When Doxygen+Graphviz is installed, CMake creates a special build task named doc. It creates actual documentation and puts it to projects/doxygen/html/ folder, which can be published to the gh-pages branch. Each merged pull request will build the docs and publish them.
Before submitting a feature or substantial code contribution please discuss it with the team and ensure it follows the product roadmap. Note that all code submissions will be rigorously reviewed and tested by the Rx Team, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source.
You will be prompted to submit a Contributor License Agreement form after submitting your pull request. This needs to only be done once for any Microsoft OSS project. Fill in the Contributor License Agreement (CLA).
This project has adopted the Microsoft Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact [email protected] with any additional questions or comments.
