DynaMo is a software library providing classes that take care of the calculation of the motions of objects under the influence of force, torque, and impulse. It can also compute forces for you through the mechanism of constraints. These allow you to easily connect geometries to each other in various ways. A constraint only has to be specified once, and the library will continually enforce it from that moment on by applying the required reaction forces. Over a dozen constraints available, includi
smart_conditions is a C++11 library that lets you refactor repetitive and potentially unreadable/error-prone boolean conditions into something more readable and maintainable.
When parsing JSON messages, most C/C++ libraries employ a DOM-based approach, i.e. they work by building an in-memory representation of object, and the client can then create/read/update/delete the properties of the object as needed, and most importantly access them in whatever order. While this is very convenient and provides maximum flexibility, there are situations in which memory allocations must or should preferably be avoided. minijson_reader is a callback-based parser, which can effective

It provides a built-in media library and audio/video player, allows to share contents per WiFi; and is also available as Android app.
When writing JSON messages, some C/C++ libraries work by building an in-memory object for the sole purpose of serialising it as JSON. Many libraries comprise multiple header and source files and/or expose a complex API. minijson_writer is a simple decorator around a std::ostream. It directly writes on the stream without allocating additional memory, and does not throw exceptions unless the stream does. Despite being a single header file of ~500 lines, minijson_writer is complete and can be eas
