This package provides a TOML parser and JSON encoder.

Package gettext provides bindings for https://www.gnu.org/software/gettext/.

This package provides a High Performance, Feature-Rich Idiomatic codec/encoding library for msgpack, JSON.

Supported Serialization formats are:

• msgpack: https://github.com/msgpack/msgpack

• json: http://json.org http://tools.ietf.org/html/rfc7159

This package provides a library for building interactive and accessible prompts on terminals supporting ANSI escape sequences.

subcommands implements a functionality for a single command to have many subcommands, each of which takes arguments.

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

This package provides a small error library that augments the errors library in go standard library.

Package userns provides utilities to detect whether we are currently running in a Linux user namespace.

This package (type inf.Dec) implements a "infinite-precision" decimal arithmetic.

This package provides a simple byte size formatting in Go.

Package zstd is a collection of extensions to Go's standard library.

Package poller is a file-descriptor multiplexer. It allows concurrent Read and Write operations from and to multiple file-descriptors without allocating one OS thread for every blocked operation. It operates similarly to Go's netpoller (which multiplexes network connections) without requiring special support from the Go runtime. It can be used with tty devices, character devices, pipes, FIFOs, and any file-descriptor that is poll-able, can be used with select(2), epoll(7), etc.

In addition, package poller allows the user to set timeouts (deadlines) for read and write operations, and also allows for safe cancellation of blocked read and write operations; a Close from another go-routine safely cancels ongoing (blocked) read and write operations.

It's an active fork of https://github.com/npat-efault/poller.

Package lexer provides generating actionless scanners (lexeme recognizers) at run time.

This package makes it a breeze to check and modify file permission bits.

This package provides x86_64 variant of ported from a Python module PeachPy, with some adaption to the Go language features.

This package provides a C99 compiler front end.

Package digest provides a generalized type to opaquely represent message digests and their operations within the registry. The Digest type is designed to serve as a flexible identifier in a content-addressable system. More importantly, it provides tools and wrappers to work with hash.Hash-based digests with little effort.

This package provides a ordered map library that maintains amortized O(1) for Set, Get, Delete and Len.

File system notifications for Go

This package implements Swiss Tables as described in https://abseil.io/about/design/swisstables. It provides pseudo-randomized iteration (iteration order will change from one iteration to the next) and iteration stability akin to Go's builtin map if the map is mutated during iteration.

This package implements a restriction for the current processes' ability to use files, using Linux 5.13's Landlock feature.

A Go library providing various concurrency utilities including a backport of sync.Map to Go versions below 1.9 and a cancellable Goroutine with explicit ownership.
