This package provides Go concurrency primitives in addition to the ones provided by the language and sync and sync/atomic packages. The package provides several Golang submodules:

• errgroup - synchronization, error propagation, and Context cancellation for groups of goroutines working on subtasks of a common task

• semaphore - a weighted semaphore implementation

• singleflight - a duplicate function call suppression mechanism

• syncmap - a concurrent map implementation

This package provides error, which offers simple error handling primitives in Go.

This package provides supplemental Go libraries for text processing.

The config package holds the config.json file defining the Go telemetry upload configuration and contains no actual Go code, and exists only so the config.json file can be served by module proxies.

An upload configuration specifies the set of values that are permitted in telemetry uploads: GOOS, GOARCH, Go version, and per-program counters.

The avo package presents a familiar assembly-like interface that simplifies development without sacrificing performance.

This package provides supplemental Go networking libraries.

This package provides Go support for the Protocol Buffers data serialization format.

Package typeparams contains common utilities for writing tools that interact with generic Go code, as introduced with Go 1.18.

Many of the types and functions in this package are proxies for the new APIs introduced in the standard library with Go 1.18. For example, the typeparams.Union type is an alias for go/types.Union, and the ForTypeSpec function returns the value of the go/ast.TypeSpec.TypeParams field. At Go versions older than 1.18 these helpers are implemented as stubs, allowing users of this package to write code that handles generic constructs inline,even if the Go version being used to compile does not support generics.

renameio Go package provides a way to atomically create or replace a file or symbolic link.

This package provides an emoji is a extension for the goldmark.

This package provides most of the code for running a godoc server.

This package provides miscellaneous tools that support the Go programming language.

Package packagestest creates temporary projects on disk for testing go tools on.

This package provides supplemental Go networking libraries.

This subrepository holds experimental and deprecated (in the old directory) packages.

This repository holds packages for writing tools that work directly with Go module mechanics. That is, it is for direct manipulation of Go modules themselves.

The specific case of loading packages should still be done by invoking the go command, which remains the single point of truth for package loading algorithms.

This package holds the transition packages for the new Go 1.13 error values.

The uuid package generates and inspects UUIDs based on RFC 4122 and DCE 1.1: Authentication and Security Services.

This repository contains packages for accessing and analyzing data from the Go Vulnerability Database.

This package provides supplementary cryptographic libraries for the Go language.

This package provides a rpc Google's API gRPC type derived from google.golang.org/protobuf.

This package provides supplemental libraries offering Go support for low-level interaction with the operating system.

The protobuf package provides a Go implementation of Protocol Buffers, a language and platform neutral, extensible mechanism for serializing structured data. It is a successor to go-github-com-golang-protobuf with an improved and cleaner API.

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.
