Retina Interpreter

Retina

Logo inspired language, based on image generation. Each program has a 'pen' and commands to draw with it.

Interpreter

Made with Haskell for a project in the Translators and Interpreters course at Universidad Simon Bolivar. Made with the help of Alex and Happy.

Interpreter made by: Augusto Hidalgo and Genesis Kufatty

Examples:

Example 1:

program
    for k from 1 to 10 do
        for i from 1 to 50 do
            forward(1);
            rotatel(1);
        end;
        for i from 1 to 90 do
            forward(1);
            rotater(1);
        end;
    end;
end;

Example 2:

program
    with
    do
        for i from 1 to 100 do
            forward(i * 2); # Traza una línea por 50 puntos
            rotater(90); # Gira 90 grados sentido horario
        end;
    end;
end;

Example 3:

program
    with
        number l=100;
        number nvertex = 5;
    do
        rotatel(1);
        for i from 1 to nvertex do
            forward(l);
            rotatel(70);
            forward(l);
            rotater(70+360/nvertex);
        end;
    end;
end;

Example 4:

program
    for k from 3 to 12 do
        for i from 1 to k do
            forward(60);
            rotatel(360/k);
        end;
    end;
end;

Example 5:

program
    with
        number l=110, rep=360;
        number nvertex = 5;
    do
        repeat rep times
            rotater(1);
            for i from 1 to nvertex do
                forward(l);
                rotatel(80);
                forward(l);
                rotater(80+360/nvertex);
            end;
        end;
    end;
end;

Example 6:

program
    for i from 1 to 17 do
        forward(350);
        rotater(360*8/17);
    end;
end;
