A collection of useful libraries and utilities.
multi-threaded - A threaded function or a threaded class.
If only a few functions of a class require threading, those functions offer a _mt variation. When most of a class's APIs would be affected by using multi-threading, an alias of the class itself is provided.
captureless - Use raw function pointers instead of std::function.
Many containers in feather libraries are functional in nature (state machines, event systems, etc). When storing user callbacks, the containers will default to the most flexible solution and use std::function. This can be bad for performance and can be a source of bugs due to capture lifetime mismanagement. When using _cl versions of a class, it will use raw function pointers instead, preventing the usage of lambda captures or functors.
compact - Use less memory, but tradeoff speed.
Reserved for future uses, not implemented yet. Some containers like fea::fsm, fea::event_stack and fea::event_system can become very heavy. Compact versions of these use indirections to save memory, but incurr runtime costs for doing so.
Install a recent CMake, Conan and compiler.
Tests are on by default, benchmarks are off by default.
Use FEA_TESTS and FEA_BENCHMARKS to enable/disable them.
CMake doesn't really detect your compiler's supported C++ standard well. Use FEA_CPP14=On to compile only the C++14 libraries.
Executables are output in build/bin/.
mkdir build && cd build
cmake .. -DFEA_TESTS=On -DFEA_BENCHMARKS=Off -DFEA_CPP14=Off && cmake --build .
// Optionally
cmake --build . --target install
