//! Demo of the turtle_main macro with inline code //! //! This example shows that you can write your turtle code directly //! in the function body without taking a turtle parameter. use turtle_lib::*; #[turtle_main("Macro Demo - Inline Spiral")] fn draw_spiral() { turtle.set_pen_color(RED); turtle.set_pen_width(2.0); for i in 0..36 { turtle.forward(i as f32 * 3.0); turtle.right(25.0); } }
