C2

Website | Source

The C2 project attempts to create a new language, strongly based on C. In a nutshell, the main differences with C are:

Higher development speed
Same/better speed of execution
Better compilation times
Integrated build system
Stricter syntax (easier for tooling)
Great tooling (formatting tool, graphical refactoring tool)
Easy integration with C libraries
Should be easy to learn for C programmers
Should help to avoid common mistakes

As C2 is an evolution of C, it also has explicit non goals:

higher-level features (like object-orientation, garbage collection, etc.)
to be a completely new language

Example

Hello world:

module hello_world;

import stdio as io;

fn i32 main(i32 argc, char** argv) {
    io.printf("Hello World!\n");
    return 0;
}
