A pure Roc turtle library with no effects, the final drawing is converted to an SVG string and can be saved to a file for viewing.

Usage

Add the roc-turtle package to your header.

app [main] {turtle: "..."}

Import the Turtle module.

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 } }
