1. Structs and methods

structs, functions, and string interpolation

module main

struct Point {
mut:
	x f64
	y f64
}

fn (p Point) distance() f64 {
	return p.x * p.x + p.y * p.y
}

fn main() {
	p := Point{x: 3.0, y: 4.0}
	println("distance = ${p.distance()}")

2. Options and matching

option types, match, and enums

enum Color {
	red
	green
	blue
}

fn parse(s string) ?Color {
	return match s {
		"red" { Color.red }
		"green" { Color.green }
		else { none }
	}
}

atom-one-dark

enum Color {

		else { none }
	}

3. Comptime keywords and raw strings

$if/$else and non-interpolating r'...' strings

fn describe() string {
	$if windows {
		return 'windows build'
	} $else {
		return 'other platform'
	}
}

fn literal_path() string {
	// raw string: ${name} is NOT interpolated here
	return r'C:\Users\${name}'
}

	$if windows {
