liburlparser 2.0.0

Fastest domain extractor library written in C++ with python binding.

First and complete library for parsing url in C++ and Python and Command Line

About The Project

liburlparser is a powerful domain extractor library written in C++ with Python bindings. It provides efficient URL parsing capabilities for both C++ and Python, making it a valuable tool for projects that involve working with web addresses.

Features

Here are some key features of liburlparser:

1. Multiple Language Support:

   • liburlparser can be used in multiple programming languages, including Python, C++, and Shell.
   • It offers an intuitive interface that remains consistent across both C++ and Python.

2. Clean Code Design:

   • The library provides separate classes for each concept: Url, and Hostname/IPv4/IPv6 for whatever a URL's host actually is (RFC 3986 defines a host as either a domain name or an IP address, never both - liburlparser mirrors that directly instead of forcing IP addresses through domain-name-shaped fields).
   • This separation allows for cleaner and more organized code when dealing with URLs.

3. Public Suffix List Support:

   • liburlparser supports known combinatorial suffixes (e.g., "ac.ir") using the public_suffix_list.
   • It can also handle unknown suffixes (e.g., "comm" in "google.comm").

4. Automatic Public Suffix List Updates:

   • Before each build and deployment, liburlparser updates the public_suffix_list automatically.

5. Hostname Properties:

   • The Hostname class includes properties such as subdomain, domain, domain name, and suffix.

6. IPv4 / IPv6 Support:

   • IPv4/IPv6 addresses used as a URL's host are recognized and parsed as such - not run through domain-name logic. Both support integer conversion and arithmetic (+, -, +=, -=, increment/decrement).

7. URL Properties:

   • The Url class provides properties like protocol, userinfo, host (classified as Hostname/IPv4/IPv6), port, path, query parameters, and fragment.

Usage

Command Line

python -m liburlparser --help # show help section
python -m liburlparser --version # show version
python -m liburlparser --url "https://mail.google.com/about" | jq #return as json
python -m liburlparser --host "mail.google.com" | jq # return as json

Python

you can use liburlparser so intutively

all of classes has help section

import liburlparser
help(liburlparser)
print(liburlparser.__version__)

from liburlparser import Url, Hostname, IPv4, IPv6
help(Url)
help(Hostname)

parse url and host

from liburlparser import Url, Hostname, Host
## parse url:
url = Url("https://ee.aut.ac.ir/#id") # parse all part of url
print(url, url.host_text, url.fragment, url.host, url.to_dict(), url.to_json())
## url.host is a Hostname, IPv4, or IPv6 object - whichever this URL's host
## actually is (an IP address has no "domain"/"suffix", so it's simply not
## forced through Hostname at all)
host = url.host  # a Hostname, here: ee.aut.ac.ir
# or
host = Hostname("ee.aut.ac.ir")
# or
host = Hostname.from_url("https://ee.aut.ac.ir/#id") # the fastest way for parsing host from url
print(host, host.domain, host.suffix, host.to_dict(), host.to_json())

## for a host you don't know in advance is a domain or an IP, use Host():
host2 = Host("192.168.1.1")   # is_ipv4() -> True
host3 = Host("ee.aut.ac.ir")  # is_hostname() -> True
print(host2.is_ipv4(), host2, int(host2.get_ipv4()))          # True 192.168.1.1 3232235777
print(host3.is_hostname(), host3, host3.get_hostname().domain) # True ee.aut.ac.ir aut

IPv4/IPv6 addresses support integer conversion and arithmetic:

from liburlparser import IPv4, IPv6

ip = IPv4("192.168.1.1")
print(int(ip))          # 3232235777
print(ip + 1)            # 192.168.1.2
print(ip - IPv4("192.168.1.0"))  # 1 (distance between two addresses)

ip6 = IPv6("2001:db8::1")
print(ip6.high64, ip6.low64)
print(ip6 + 1)            # 2001:db8::2

Also there is some helping api to get better performance for some small tasks

# if you need to extract the host of url as a string without any parsing
host_str = Url.extract_host("https://ee.aut.ac.ir/about") # very fast

C++

there is some examples in examples folder

#include "urlparser.h"
...
/// for parsing url
urlparser::url url("https://ee.aut.ac.ir/about");
std::string_view host_text = url.host_text(); // the raw host text, unclassified

/// url.host() is a urlparser::host (hostname/ipv4/ipv6, whichever this
/// URL's host actually is)
if (auto* h = url.host().try_hostname()) {
    std::cout << h->domain() << "." << h->suffix();
}

/// for parsing a host you already have (or a full URL) directly:
urlparser::hostname host("ee.aut.ac.ir");
// or
urlparser::hostname host2 = urlparser::hostname::from_url("https://ee.aut.ac.ir/about");
// or, when you don't know in advance whether it's a domain or an IP:
urlparser::host classified = urlparser::host::from_url("http://192.168.1.1/about"); // -> is_ipv4() true

you can see all methods in python we can use in c++ very easily

Installation

C++:

build steps:

# 1. Clone the repository with submodules (recursive)
# --recursive is essential to download third-party libs like googletest
git clone --recursive https://github.com/mohammadraziei/liburlparser
cd liburlparser

# 2. Configure the project
# -B build tells CMake to create a 'build' directory and generate files there
cmake -B build

# 3. Build the project
# --build abstracts the underlying build tool (Make, Ninja, MSBuild, etc.)
cmake --build build --config Debug

# 4. Run examples
# Note: On Windows, the path might be ./build/Debug/example.exe
./build/example

# 5. Make install
# --install handles the installation process
sudo cmake --install build

Python and Command Line:

Be aware that it required python>=3.8

Installation

To install from source, you must ensure all submodules are cloned:

# 1. Clone recursively to get third-party dependencies
git clone --recursive https://github.com/mohammadraziei/liburlparser
cd liburlparser

# 2. Install using pip
pip install .

# Optional: If you want to see build logs
pip install . -v
