Syntax highlighting

Code blocks are highlighted at build time with syntect, so no JavaScript is involved and highlighting also works in single-file output. Colors follow the reader's light or dark mode.

fn main() {
    let pages = ["index.md", "usage.md"];
    for p in pages.iter().filter(|p| p.ends_with(".md")) {
        println!("rendering {p}");
    }
}

from pathlib import Path

def titles(root: Path) -> dict[str, str]:
    """First heading of every markdown file."""
    return {p.name: p.read_text().splitlines()[0].lstrip("# ") for p in root.rglob("*.md")}

for f in docs/*.md; do
  echo "$f: $(head -1 "$f")"
done

{ "name": "webolator", "config": null }

Use the language's name or file extension after the fence (rust, py, sh and so on). A block with no language, or a language syntect doesn't know, is shown as plain text. The Syntax reference lists every supported language.
