Package semver provides the ability to work with Semantic Versions in Go.

This package provides jbenet's context extensions.

This package can be used to return the elapsed time since a given time in a human-readable format.

Package sortutil provides utilities supplementing the standard sort package.

The vtclean provides the vtclean command and a library designed to clean up raw terminal output by stripping escape sequences, optionally preserving color.

A .gitignore parser for Go.

This package provides a functionality to generate type-safe converters for Go. The project is meant as alternative to jinzhu/copier that doesn't use reflection.

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

This package provides a minimal interface for structured logging in services. It may be wrapped to encode conventions, enforce type-safety, provide leveled logging, and so on. It can be used for both typical application log events, and log-structured data streams.

This package provides an implementation of the Unicode Text Segmentation specification for Go. Specifically, it currently includes only the grapheme cluster segmentation algorithm.

Package levenshtein implements distance and similarity metrics for strings, based on the Levenshtein measure.

This package provides an alternative implementation of regexp, with some code optimisations to make it run faster.

Perks contains the Go package quantile that computes approximate quantiles over an unbounded data stream within low memory and CPU bounds.

This package provides the shellescape.Quote to escape arbitrary strings for a safe use as command line arguments in the most common POSIX shells.

runewidth provides functions to get fixed width of the character or string. It is a fork of https://github.com/mattn/go-runewidth, updated to the newest Unicode and having various helper functions removed, so all that remains is just the runewidth.RuneWidth() function.

Suture provides Erlang-ish supervisor trees for Go. "Supervisor trees" -> "sutree" -> "suture" -> holds your code together when it's trying to die.

It is intended to deal gracefully with the real failure cases that can occur with supervision trees (such as burning all your CPU time endlessly restarting dead services), while also making no unnecessary demands on the "service" code, and providing hooks to perform adequate logging with in a production environment

Package cellbuf provides terminal cell buffer functionality.

cty (pronounced "see-tie") is a dynamic type system for applications written in Go that need to represent user-supplied values without losing type information. The primary intended use is for implementing configuration languages, but other uses may be possible too.

Moby is an open-source project created by Docker to enable and accelerate software containerization.

This package provides an implementation of the Unicode Text Segmentation specification for Go. Specifically, it currently includes only the grapheme cluster segmentation algorithm.

This package implements a pure Go driver and toolkit for PostgreSQL. It is different from other drivers such as pq because, while it can operate as a database/sql compatible driver, pgx is also usable directly. It offers a native interface similar to database/sql that offers better performance and more features.

This package provides function FieldByName to access to any field (including private/unexported) of a structure.

The uuid package generates and inspects UUIDs based on RFC 4122 and DCE 1.1: Authentication and Security Services. This package now leverages the github.com/google/uuid package (which is based off an earlier version of this package).

This package implements a simple XML 1.0 parser that understands XML name spaces, along with extended support for control characters.
