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

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.

This package provides various Protocol Buffer extensions for the Go language, namely support for record length-delimited message streaming.

term provides support functions for dealing with terminals, as commonly found on Unix systems.

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

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 error, which offers simple error handling primitives in Go.

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

This package provides supplemental Go libraries related to time.

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

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

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

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

This package provides supplemental Go libraries for text processing.

This package provides various Protocol Buffer extensions for the Go language (golang), namely support for record length-delimited message streaming.

Juniper is a library of extensions to the Go standard library using generics, including containers, iterators, and streams.

• container/tree contains a Map and Set that keep elements in sorted order. They are implemented using a B-tree, which performs better than a binary search tree.

• container/deque contains a double-ended queue implemented with a ring buffer.

• container/xheap contains a min-heap similar to the standard library's container/heap but more ergonomic, along with a PriorityQueue that allows setting priorities by key.

• container/xlist contains a linked-list similar to the standard library's container/list, but type-safe.

• xslices contains some commonly-used slice operations, like Chunk, Reverse, Clear, and Join.

• iterator contains an iterator interface used by the containers, along with functions to manipulate them, like Map, While, and Reduce.

• stream contains a stream interface, which is an iterator that can fail. Useful for iterating over collections that require I/O. It has most of the same combinators as iterator, plus some extras like Pipe and Batch.

• parallel contains some shorthand for common uses of goroutines to process slices, iterators, and streams in parallel, like parallel.MapStream.

• xsort contains extensions to the standard library package sort. Notably, it also has the definition for xsort.Less, which is how custom orderings can be defined for sorting and also for ordered collections like from container/tree.

• You can probably guess what's in the packages xerrors, xmath, xmath/xrand, xsync, and xtime.

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

This package provides a mirror of the assembler from the Go compiler, with import paths re-written for the assembler to be functional as a standalone library.

This package provides an in-memory B-Tree implementation for Go, useful as an ordered, mutable data structure.

This package provides supplemental Go networking libraries.

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