Here’s a minimal SDL3 program that creates a window:

#lang racket/base

(require racket/match sdl3)

(with-sdl

(with-window+renderer "Hello SDL3" 800 600 (win ren)

(let loop ()

(define quit?

(for/or ([ev (in-events)])

(match ev

[(quit-event) #t]

[(key-event 'down 'escape _ _ _) #t]

[_ #f])))

(unless quit?

(set-draw-color! ren 100 149 237)

(render-clear! ren)

(render-present! ren)

(loop)))))
