codin

An Odin to C compiler written in C.

Building

To build on Linux

$ make

On Linux you have some additional build options provided by the Makefile. Check the documentation at the top of the Makefile for them.

To build on Windows

$ cl.exe unity.c

Running

Currently only the build and run commands are supported and only for a single source file.

$ ./codin build tests/main.odin -file
$ ./codin run tests/main.odin -file

Windows

On Windows you'll need to have Visual Studio installed. Just run codin from the x64 Native Tools Command Prompt for VS.

Linux

On Linux you'll need to have gcc installed and in your PATH.

  x, y, z: i32 = 10, 20, 30;
  s: string = "world";
  fmt.printf("Hello %s %d\n", s, -x + y * z - 1);
}
