This library provides:

• A skyr::url class that implements a generic URL parser, conforming with the WhatWG URL specification
• URL serialization and comparison
• Percent encoding and decoding functions
• IDNA and Punycode functions for domain name parsing

This project requires the availability of a C++17 compliant compiler and standard library.

From a terminal, execute the following sequence of commands:

> mkdir _build
> cd _build
> cmake .. -G "Ninja"
> ninja

To run the tests, run ninja test from the terminal while in the _build directory:

> ninja test

Open Visual Studio 2017, and click on File->Open->Folder, or use the shortcut Ctrl+Shift+Alt+O. Open the root folder of this project. This will load the project in the explorer. To build, simply open the CMake menu and click Build All.

To run the tests, open the CMake menu, click Tests and then run Run Skyr CTests.

These examples are based on the WhatWG API specification

To build the examples, run cmake as follows:

> cmake .. -G "Ninja" -DSkyr_BUILD_EXAMPLES=ON

This example parses a string, "https://example.org/💩", without using a base URL:

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

int main(int argc, char *argv[]) {
  auto url = skyr::make_url("http://example.org/\xf0\x9f\x92\xa9");
  std::cout << url.value().pathname() << std::endl;
}

Gives the output: /%F0%9F%92%A9

This gives an error if the input, "/🍣🍺", is not an absolute-URL-with-fragment-string:

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

int main(int argc, char *argv[]) {
  auto url = skyr::make_url("\xf0\x9f\x8d\xa3\xf0\x9f\x8d\xba");
  if (!url) {
    std::cerr << "Parsing failed: " << url.error().message() << std::endl;
  }
}

This gives the output: Parsing failed: Not an absolute URL with fragment

This example parses a string, "🏳️‍🌈", using a base URL, "https://example.org/":

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

int main(int argc, char *argv[]) {
  auto base = skyr::make_url("https://example.org/");
  auto url = skyr::make_url(
    "\xf0\x9f\x8f\xb3\xef\xb8\x8f\xe2\x80\x8d\xf0\x9f\x8c\x88", base.value());
  if (url) {
    std::cout << url.value().href() << std::endl;
  }
}

This gives the output: https://example.org/%F0%9F%8F%B3%EF%B8%8F%E2%80%8D%F0%9F%8C%88

> cmake .. -G "Ninja" -DCMAKE_INSTALL_PREFIX=$PREFIX
> ninja
> ninja test      # optional
> ninja install

Where $PREFIX is the location where you want to install the library. Depending on the location of $PREFIX, you may need to run the install command as an administrator (e.g. on Linux as sudo).

Open the CMake menu, click Install, then Skyr.
