Using a FORTH-like language for something useful

22 September 2020 13:00

So my previous post was all about implementing a simple FORTH-like language. Of course the obvious question is then "What do you do with it"?

So I present one possible use - turtle-graphics:

\ Draw a square of the given length/width
: square
  dup dup dup dup
  4 0 do
    forward
    90 turn
  loop
;

\ pen down
1 pen

\ move to the given pixel
100 100 move

\ draw a square of width 50 pixels
50 square

\ save the result (png + gif)
save

Exciting times!
