This is a general overview of the features that comes with Clash.

socketpair is a Go library that provides bidirectionally connected net.Conns, net.PacketConns made from socketpair(2) as well as bidirectionally connected net.TCPConns.

provides a pure Go implementation of Universally Unique Identifiers (UUID) variant as defined in RFC-4122. This package supports the following UUID versions:

Version 1, based on timestamp and MAC address (RFC-4122) Version 3, based on MD5 hashing of a named value (RFC-4122) Version 4, based on random numbers (RFC-4122) Version 5, based on SHA-1 hashing of a named value (RFC-4122)

DHCPv4 decoding/encoding library with client and server code, written in Go.

Package gostub is used for stubbing variables in tests, and resetting the original value once the test has been run.

Open web browser by xdg-open or other method

simple implementation of RFC1035 labels, used by dhcpv6 and dhcpv4

Package automaxprocs automatically sets GOMAXPROCS to match the Linux container CPU quota, if any.

Package netns allows ultra-simple network namespace handling. NsHandles can be retrieved and set. Note that the current namespace is thread local so actions that set and reset namespaces should use LockOSThread to make sure the namespace doesn't change due to a goroutine switch. It is best to close NsHandles when you are done with them. This can be accomplished via a `defer ns.Close()` on the handle. Changing namespaces requires elevated privileges, so in most cases this code needs to be run as root.

cors package is net/http handler to handle CORS related requests as defined by @urlhttp://www.w3.org/TR/cors/,http://www.w3.org/TR/cors/

Only for Windows, but some Go library need this

This package is intended to be a more powerful and safer alternative to @codereflect.DeepEqual for comparing whether two values are semantically equal.

some wrapper for htpp.FilSystem provode: 1. keep or skip files 2. io utility function

This package provides access to Linux packet sockets (AF_PACKET) in Go

Package netlink provides low-level access to Linux netlink sockets (AF_NETLINK).

ebpf-go is a pure Go library that provides utilities for loading, compiling, and debugging eBPF programs.

GopherJS compiles Go code (@urlhttps://golang.org/,golang.org) to pure JavaScript code. Its main purpose is to give you the opportunity to write front-end code in Go which will still run in all browsers.

Package rtnetlink allows the kernel's routing tables to be read and altered. Network routes, IP addresses, Link parameters, Neighbor setups, Queueing, disciplines, Traffic classes and Packet classifiers may all be controlled. It is based on netlink messages.

provides a series of methods for big-endian and little-endian number operations

offering a few simple helpers and interfaces to provide a simple pattern for managing payload encoding and decoding.
