Gore is a Go REPL that offers line editing and auto-completion. Some of its features include:

• Line editing with history

• Multi-line input

• Package importing with completion

• Evaluates any expressions, statements and function declarations

• No ``evaluated but not used'' errors

• Code completion

• Showing documents

• Auto-importing (gore -autoimport)

gomacro is an almost complete Go interpreter, implemented in pure Go. It offers both an interactive REPL and a scripting mode, and does not require a Go toolchain at runtime (except in one very specific case: import of a 3rd party package at runtime).

The godef command prints the source location of definitions in Go programs.

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

This package provides supplemental Go networking libraries.

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.

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

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

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

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.

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

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.

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.

This package provides supplementary cryptographic libraries for the Go language.

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 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

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 provides supplemental Go libraries related to time.

This package provides supplemental Go libraries for image processing.

Mage is a make-like build tool using for Go. It implements a functionality of writing plain-old go functions which Mage automatically uses as Makefile-like runnable targets consistent across a project. This package provides a source library and built command mage.

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

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

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