Code copy test

A Python block:

def greet(name: str) -> str:
    return f"hello, {name}"

print(greet("world"))

A shell block (expressive-code renders these in a terminal frame by default):

docker compose up -d
docker compose logs -f caddy

A TypeScript block with a filename, which expressive-code uses as the frame title:

export function setMode(mode: 'light' | 'dark') {
  document.documentElement.dataset.mode = mode;
}
