This package implements Swiss Tables as described in https://abseil.io/about/design/swisstables. It provides pseudo-randomized iteration (iteration order will change from one iteration to the next) and iteration stability akin to Go's builtin map if the map is mutated during iteration.

The cmdtest package simplifies testing of command-line interfaces. It provides a simple, cross-platform, shell-like language to express command execution. It can compare actual output with the expected output, and can also update a file with new "golden" output that is deemed correct.

This package implements a functinality to help filling out plain html forms during testing. Will automatically take the existing values from the form so there is no need to manually set things like csrf tokens. Alerts about missing required fields, or when pattern validation does not match.

This package implements functionality for encoding and decoding Concise Binary Object Representation (RFC 8949) and CBOR Sequences, with CBOR tags, Golang struct tags (toarray, keyasint, omitempty), float64/32/16, and big.Intp.

Package terminal is a vt10x terminal emulation backend, influenced largely by st, rxvt, xterm, and iTerm as reference. Use it for terminal muxing, a terminal emulation frontend, or wherever else you need terminal emulation.

It's an active fork of https://github.com/james4k/terminal.

This package provides a Golang library for parsing Intel HEX files, implementing features like:

• robust intelhex parsing (full test coverage)

• support i32hex format

• two-way converting hex<->bin

• trivial but powerful api (only the most commonly used functions)

• interface-based IO functions

Package assertions contains the implementations for all assertions which are referenced in goconvey's convey package and gunit gunit for use with the So(...) method. They can also be used in traditional Go test functions and even in applications.

Keyring provides utility functions for and a common interface to a range of secure credential storage services. Originally developed as part of AWS Vault, a command line tool for securely managing AWS access from developer workstations.

Currently Keyring supports the following backends: macOS/OSX Keychain, Windows pcredential store, Pass, Secret Service, KDE Wallet, Encrypted File.

This package provides a Go implementation of JSON Web Tokens and supports the parsing and verification as well as the generation and signing of JSON Web Tokens. The currently supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.

Datastore is a generic layer of abstraction for data store and database access. It is a simple API with the aim to enable application development in a datastore-agnostic way, allowing datastores to be swapped seamlessly without changing application code. Thus, one can leverage different datastores with different strengths without committing the application to one datastore throughout its lifetime.

Package errors provides a robust error handling library with support for error wrapping, stack traces, context storage, and retry mechanisms. It extends the standard library's error interface with features like HTTP-like status codes, error categorization, and JSON serialization, while maintaining compatibility with `errors.Is`, `errors.As`, and `errors.Unwrap`. The package is thread-safe and optimized with object pooling for performance.

This package provides Go libraries that are shared across Prometheus components.

• config - common configuration structures

• expfmt - decoding and encoding for the exposition format

• model - shared data structures

• promslog - a logging wrapper around log/slog

• route - a routing wrapper around httprouter using context.Context

• server - common servers

• version version information and metrics

ChunkReader is a io.Reader wrapper that minimizes IO reads and memory allocations. It allocates memory in chunks and will read as much as will fit in the current buffer in a single call regardless of how large a read is actually requested. The memory returned via Next is owned by the caller. This avoids the need for an additional copy. It extracted from original implementation in https://github.com/jackc/pgx.

Suture provides Erlang-ish supervisor trees for Go. "Supervisor trees" -> "sutree" -> "suture" -> holds your code together when it's trying to die.

It is intended to deal gracefully with the real failure cases that can occur with supervision trees (such as burning all your CPU time endlessly restarting dead services), while also making no unnecessary demands on the "service" code, and providing hooks to perform adequate logging with in a production environment

DHCPv4 and DHCPv6 decoding/encoding library for Golang. This package is split in several logical parts:

• dhcpv4 - implementation of DHCPv4 packet, client and server

• netboot - network booting wrappers on top of dhcpv6 and dhcpv4

• iana - several IANA constants, and helpers used by dhcpv6 and dhcpv4

• rfc1035label - simple implementation of RFC1035 labels, used by dhcpv6 and dhcpv4

• interfaces - a thin layer of wrappers around network interfaces

Ironwood is a routing library with a net.PacketConn-compatible interface using ed25519.PublicKeys as addresses. Basically, you use it when you want to communicate with some other nodes in a network, but you can't guarantee that you can directly connect to every node in that network. It was written to test improvements to / replace the routing logic in Yggdrasil, but it may be useful for other network applications.

This package provides a library for calling C functions from Go without Cgo.

Featues:

• build for other platforms easily without a C compiler

• efficiently cache entirely Go builds

• using Cgo generates a C wrapper function for each C function called

• load symbols at runtime and use it as a plugin system

• call into other languages that are compiled into shared objects

• works even with CGO_ENABLED=1 so incremental porting is possible

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.

Luar is designed to make using Lua from Go more convenient. Go structs, slices and maps can be automatically converted to Lua tables and vice-versa. The resulting conversion can either be a copy or a proxy. In the latter case, any change made to the result will reflect on the source.

Any Go function can be made available to Lua scripts, without having to write C-style wrappers.

Luar support cyclic structures (lists, etc.).

User-defined types can be made available to Lua as well: their exported methods can be called and usual operations such as indexing or arithmetic can be performed.

Accelerate SHA256 computations in pure Go using AVX512 and AVX2 for Intel and ARM64 for ARM. On AVX512 it provides an up to 8x improvement (over 3 GB/s per core) in comparison to AVX2.

This package is designed as a replacement for crypto/sha256. For Intel CPUs it has two flavors for AVX512 and AVX2 (AVX/SSE are also supported). For ARM CPUs with the Cryptography Extensions, advantage is taken of the SHA2 instructions resulting in a massive performance improvement.

This package uses Golang assembly. The AVX512 version is based on the Intel's "multi-buffer crypto library for IPSec" whereas the other Intel implementations are described in "Fast SHA-256 Implementations on Intel Architecture Processors" by J. Guilford et al.
