Write without
the noise.

On Craft

Good tools disappear. They hold the work without asking to be admired — the way a well-balanced pen is felt only in the line it leaves. Rune is built on that idea: the markdown formats the moment you type it, and only the line under your cursor shows its raw source.

A small grammar

Structure is not a cage. A heading, a list, a fenced block — each is a promise about what comes next. Write the grammar and the meaning follows.

fn render(line: &str) -> Block {
    match classify(line) {
        Kind::Heading(n) => Block::heading(n, line),
        Kind::Fence      => Block::code(line),
        // everything else is prose
        _ => Block::paragraph(line),
    }
}

Structure creates freedom. The form is what lets the thought run.
