This post suggests an implementation of template class setof which facilitates features of a bit set and a forward-iterable container.
C++ does not allow using string literals as case values in a switch statement. In modern C++ this restriction can be worked around with constexpr hash values.
This simple C++17 template implements constexpr any_of for matching a value against a list of constants.

C++17 has simplified use of template parameters. Instructions, given in this tutorial, describes how to define JSON model with cojson::autos templates. Note: GCC 7 or higher is required to compile cojson_autos.hpp !
cojson v.2 offers an easy start option by using C++ code automatically generated from a JSON sample the user needs to parse or to write. To use this option just open codegen page, load or copy-&-paste your JSON and copy-&-paste or save the generated C++ code. And then build your application with cojson sources .

VLC-multiroom is a shell script that on a Linux-based media computer configures systemd to run multiple VLC Media Player instances for audio playback via all available ALSA sound cards and for web based remote control with a purpose to make the media computer the core of a multiroom audio system.
Getting Started With μcuREST you can implement REST services and/or a web application for communication with your embedded application. First you’ll need to decide which resources (variables or functions of your application) you wish to expose via HTTP and assign URI to those resources. Then define a μcuRESTresource map, binding URI names to the resources. […]
Introduction Preprocessor macros are widely used in C++ for configuring reusable modules, targeting different platforms or working around compiler’s differences. Such approach is inherited from C and used even in modern pure C++ libraries, such as boost. The aim of this work is to research on suitability of C++ templates and language features for establishing […]
