Not the person you're replying to, but I assume they're referring to the ability to see something like:

``` src ├── app │ └── page.tsx └── components └── header.tsx ```

EDIT: Lol. I'm not even going to edit it. Hacker News, you also suck.

I can see that easily in Finder. List View or Column View displays files like that.

You have to indent the text by two or more spaces to count as code. Hacker News doesn't use Markdown, so backticks don't work.

FWIW, this is clear in the "help" link by the textarea.
