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).

mnc (my next cron) opens the user's crontab and echos the time when the next cronjob will be ran.

This package implements a syntax highlighter for a long list of programming languages. It takes source code and other structured text and converts it into syntax highlighted HTML, ANSI-coloured text, etc. Chroma is based heavily on Pygments, and includes translators for Pygments lexers and styles.

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

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

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.

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 error, which offers simple error handling primitives in Go.

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.

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

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.

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

This package provides supplemental Go libraries for text processing.

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 implements logging analogous to C++ package glog INFO/ERROR/V setup. It provides functions that have a name matched by regex:.

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

This package provides supplementary cryptographic libraries for the Go language.

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

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 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 supplemental Go networking libraries.

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

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.
