rapp is a library that provides cross-platform application entry point and additional functionality. rapp is heavily based on bgfx examples entry point code that can be found here. Graphics code is still bgfx based but..

...dependecy on bx and bgfx has been removed by aggressively copying code and by a special feature of build system that allows to have the same library in a 'solution' with different configurations.
To clarify, in the screenshot below first sample (command line) links against rapp and rbase while the second one (graphics) links against rapp_bgfx, rbase, bx, bimg and bgfx - this is all automated.

Thanks to multiple configurations per project feature of build, script taking care of this is very short and can be seen here, basically it just enables a library wide define.

Features

rapp currently has the following functionality:

• Applications written as classes with init/shutdown/suspend/resume functionality
• Command line (tools, unit tests, etc.) or graphics applications (games, etc.)
• Custom commands
• Input controllers (mouse, keyboard, gamepad, etc.) with input binding callbacks and debug visualizations
• Ability to run code on main/message loop thread
• Job scheduler with job stealing for fine grained parallelism
• ImGui and NanoVG integration
• Quake like console - ImGui based
• Multiple applications in one binary
• Window functions

Here's a screenshot of a bgfx sample showing input debugging, ImGui dialog and Quake like console as well as NanoVG shape (eyes):
