The example is equivalent to one described in the WhatWG URL specification.

#include <iostream>
#include <skyr/url.hpp>

int main() {
  auto url = skyr::url("http://example.org/\xf0\x9f\x92\xa9");
  std::cout << url << std::endl;
  std::cout << url.pathname() << std::endl;
}

The skyr::url works like this: it's constructor parses the input string. Parser errors are handled by throwing a url_parse_error exception.

Once the url object is constructed, the parts can be access through accessors, such as pathname.

To build this example in a project using vcpkg and CMake, use the following set up:

cmake_minimum_required(VERSION 3.14)
project(example_01)

set(CMAKE_CXX_STANDARD 23)

find_package(tl-expected CONFIG REQUIRED)
find_package(skyr-url CONFIG REQUIRED)

add_executable(example_01 example_01.cpp)
target_link_libraries(example_01 PRIVATE skyr::url)

and to build it, run cmake like this:

> mkdir _build
> cd _build
> cmake \
  -G Ninja \
  -DCMAKE_TOOLCHAIN_FILE=${VCPKG_ROOT}/vcpkg/scripts/buildsystems/vcpkg.cmake \
  ..
> ninja
