Current version of Ć doesn't support standalone programs or even console output, so your "Hello world" could be the following library:
public class HelloCi
public static string GetMessage()
return "Hello, world!";
See here for a slightly bigger example and its translations. See ASAP and FAIL for real programs written in Ć.
How to install
cito is written in C#.
On Windows you need .NET Framework 3.5. Download cito binaries and extract cito.exe and cipad.exe to a directory in your PATH environment variable.
On other platforms install Mono. Mono runs .NET executables:
For your convenience, create Mono wrapper scripts such as:
exec /usr/bin/mono /usr/local/lib/cito/cito.exe "$@"
so that you can type cito instead of mono cito.exe.
If you want to compile cito from source code, see compilation instructions.
