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

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 miscellaneous tools that support the Go programming language.

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

This package provides a machine architecture information used by the Go toolchain. The parts needed in the main Go repository are copied in.

This package provides a markdown parser.

This repository holds the Go Telemetry server code and libraries, used for hosting telemetry.go.dev and instrumenting Go toolchain programs with opt-in telemetry.

The Common Expression Language (CEL) implements common semantics for expression evaluation, enabling different applications to more easily interoperate.

Package pdf implements reading of PDF files.

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.

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

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

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

This package provides supplementary cryptographic libraries for the Go language.

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.

Package testza is a full-featured testing framework for Go. It integrates with the default test runner, so you can use it with the standard go test tool. Testza contains easy to use methods, like assertions, output capturing, mocking, and much more.

This package implements a functionality for testing socket and HTTP servers in Golang.

assert is a testing library that provides high-level assertions API based on Go testing library procedures.

This package provides additions to Go's stdlib testing.

Ginkgo is a Behaviour-Driven Development testing framework for Go. It builds on top of Go's builtin testing library and is complemented by the Gomega matcher library.

This package reads go-structlayout JSON on stdin and reorders fields to minimize the amount of padding. It can emit JSON to feed into go-structlayout-pretty.

Package fake is the fake data generatror for go (Golang), heavily inspired by forgery and ffaker Ruby gems.
