Welcome to Rhea!

Rhea is simple programming language, created for example language interpreter.

About the name of the language

Like the rest of my project names Rhea associated with Saturn - she is second largest moon of Saturn.

You can see the grammar of the language in detail here. Rhea has 4 syntax statements:

You can declare a function with the fn keyword like rust:

fn name(arg1, arg2) = arg1 + arg2;

In rhea you are required to declare your variables before using. You can do it with let keyword like rust or js:

let a = 2;

you can not initialize your variables, then they will be initialized to zero:

let a;

After the declaration you can assign another value to your variable:

a = 3;

You can call the function, for example you can call the built-in function print:

print(2);

If your function takes more than one argument, arguments are separated by a comma:

fn mul(a, b) = a * b;
print(mul(2, 3));

Rhea has 4 operators: +, -, *, /.

All statements in Rhea must end with a semicolon.
