Ginger

Fibonacci function in ginger:

fib = {
    decr = { out = add < (in; -1;); };

    out = {
        n = 0 < in;
        a = 1 < in;
        b = 2 < in;

        out < if < (
            zero? < n;
            a;
            recur < (decr < n; b; add < (a;b;); );
        );

    } < (in; 0; 1;);
};

Usage of the function to generate the 6th fibonnaci number:

fib < 5;

Development

Current efforts on ginger are focused on a golang-based virtual machine, which will then be used to bootstrap the language. go >=1.18 is required for this vm.

If you are on a linux-amd64 machine with nix installed, you can run:

nix-shell -A shell

from the repo root and you will be dropped into a shell with all dependencies (including the correct go version) in your PATH, ready to use. This could probably be expanded to other OSs/architectures easily, if you care to do so please check out the default.nix file and submit a PR!
