A while ago Oskar Hahn shared the roc-turtle platform. I wanted to try making a turtle library that would let you use pipe the turtle value through pure functions and then output the final path as an image.
I created the roc-turtle library, and used roc-svg to convert the path to an SVG string.
Here's an example from the readme:
import turtle.Turtle
Create a Turtle
using the Turtle.new
function.
turtle = Turtle.new {}
Use functions like Turtle.forward
and Turtle.turn
to move the turtle.
path = turtle |> Turtle.forward 1 |> Turtle.turn (Num.pi / 4)
When your drawing is done, use the Turtle.toSvg
function to convert it into an SVG string which you can output to a file.
svgStr = Turtle.toSvg path { x: { from: -500, to: 500 }, y: { from: -500, to: 500 } }
