#Usage

#URL Parsing

///|
test {
  let url = @url.parse("https://user:pass@example.com:8080/path?q=1#frag")
  assert_eq(url.href(), "https://user:pass@example.com:8080/path?q=1#frag")
  assert_eq(url.hostname(), "example.com")
  @debug.assert_eq(url.port(), Some(8080))
  assert_eq(url.pathname(), "/path")
  assert_eq(url.search(), "?q=1")
  assert_eq(url.origin(), "https://example.com:8080")

  // Infallible variant — returns None instead of raising
  let opt = @url.parse_maybe("not a url", None)
  @debug.assert_eq(opt, None)

  // Resolve a relative URL
  let base = @url.parse("https://example.com/a/b/c")
  let resolved = base.join("../d")
  assert_eq(resolved.href(), "https://example.com/a/d")
}

#URLSearchParams

///|
test {
  let params = @url.UrlSearchParams::from_string("a=1&b=2&a=3")
  @debug.assert_eq(params.get("a"), Some("1"))
  @debug.assert_eq(params.get_all("a"), ["1", "3"])

  params.append("c", "4")
  params.delete("b")
  params.set("a", "99")
  assert_eq(params.to_string(), "a=99&c=4")
}

#URLPattern

///|
test {
  let p = @urlpattern.UrlPattern::from_string(
    "https://example.com/books/:id",
    None,
  )
  assert_eq(p.test_url("https://example.com/books/42"), true)

  match p.exec_url("https://example.com/books/42") {
    Some(result) =>
      match result.pathname() {
        Some(pr) =>
          match pr.groups().get("id") {
            Some(Some(id)) => assert_eq(id, "42")
            _ => assert_true(false)
          }
        None => assert_true(false)
      }
    None => assert_true(false)
  }
}

#IDNA

test {
  assert_eq(@url.domain_to_ascii("münchen.example"), "xn--mnchen-3ya.example")

    @url.domain_to_unicode("xn--mnchen-3ya.example"),
