The C++ classes and functions in this repository are designed for general purpose use. In addition, many of them are used in the Chops ("C"onnective "H"andcrafted "Op"enwork "S"oftware) libraries (e.g. Chops Net IP, an asynchronous IP networking library). The Chops libraries provide networking and distributed processing functionality and are specially useful for efficiently connecting multiple types of devices together.
More info on the utilities is here. It is also the main page of the generated Doxygen documentation.
The generated Doxygen documentation for these utilities is here.
The utilities in utility-rack do not have any third-party dependencies. They use C++ standard library headers only. The unit test code does have dependencies as noted below.
This software is compiled with the C++ 20 standard, although some of the idioms were written for C++ 17 and may have newer and more modern implementations. C++ 20 features such as concepts / requires will be added.
Continuous integration workflows build and unit test on g++ (through Ubuntu), MSVC (through Windows), and clang (through macOS).
The unit test code uses Catch2. If the UTILITY_RACK_BUILD_TESTS flag is provided to Cmake (see commands below) the Cmake configure / generate will download the Catch2 library as appropriate using the CPM.cmake dependency manager. If Catch2 (v3 or greater) is already installed using a different package manager (such as Conan or vcpkg), the CPM_USE_LOCAL_PACKAGES variable can be set which results in find_package being attempted. Note that v3 (or later) of Catch2 is required.
Specific version (or branch) specs for the Catch2 dependency is in the test/CMakeLists.txt file, look for the CPMAddPackage command.
To build and run the unit test program:
First clone the utility-rack repository, then create a build directory in parallel to the utility-rack directory (this is called "out of source" builds, which is recommended), then cd (change directory) into the build directory. The CMake commands:
cmake -D UTILITY_RACK_BUILD_TESTS:BOOL=ON ../utility-rack
cmake --build .
ctest
For additional test output, run the unit test individually, for example:
test/erase_where_test -s
test/byte_array_test -s
The example can be built by adding -D UTILITY_RACK_BUILD_EXAMPLES:BOOL=ON to the CMake configure / generate step.
