This package provides supplementary cryptographic libraries for the Go language.

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

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.

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.

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

Gocc is a compiler kit for Go written in Go. Gocc generates lexers and parsers or stand-alone DFAs or parsers from a BNF. Lexers are DFAs, which recognise regular languages. Gocc lexers accept UTF-8 input. Gocc parsers are PDAs, which recognise LR-1 languages. Optional LR1 conflict handling automatically resolves shift / reduce and reduce / reduce conflicts.

Package pdf implements reading of PDF files.

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

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 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.

Package expect provides support for interpreting structured comments in Go source code (including go.mod and go.work files) as test expectations.

This package provides supplemental Go libraries for text processing.

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.

Package oglemock provides a mocking framework for unit tests.

gotestspace is used to quickly create a working directory for shell execution using Go, as well as a tool for customizing the execution of the shell. It can help you quickly create an independent workspace for unit testing and improve the efficiency of unit test writing.

go-testmark is a library to parse, patch data and test fixtures from Markdown files, using the testmark format, which itself is a subset of Markdown format.

This package provides ciinfo, a tool to get details about the current Continuous Integration environment, including checking if running in a CI system, which CI system, build id, and more.

This is a reimplementation of ci-info in Go.

This is a straight copy of the excellent Gomega library, stripped to the bare core to be free of third-party dependencies.

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.

This package provides an implementation of failpoints for Golang.

@codego-vcr simplifies testing by recording your HTTP interactions and replaying them in future runs in order to provide fast, deterministic and accurate testing of your code.

This package provides the Go source code for the go-staticcheck advanced Go linter.

This package implements a functionality to mock a PostgreSQL server.

This package implements a tool to compile native Golang fuzzers to libFuzzer fuzzers.
