• simple API

• colors on Linux

• set leveling via environmental variables LOGGER=trace|debug|info|warn|error

Package xdg provides functions related to freedesktop.org.

Package gopoet is a library to assist with generating Go code. It includes a model of the Go language that is simpler, and thus easier to work with, than those provided by the go/ast and go/types packages. It also provides adapter methods to allow simple interoperability with elements from the go/types and reflect packages.

This package implements functionality to encode and decode DRCS Sixel.

This is a weakref map for Go 1.18, with some inspiration from xeus2001's weakref implementation.

This provides both a weak.Ref object to store weak references, and a weak.Map object for maps.

Bleve is a Go library for indexing and searching text, numeric, geo-spatial and vector data.

runc is a CLI tool and library for spawning and running containers on Linux according to the OCI specification.

This package is a Go implementation of the zap file format. The zap file format is used by the bleve search engine to store its indexes. It is documented at https://github.com/blevesearch/zapx/blob/master/zap.md. It was originated as https://github.com/blevesearch/zap.

This package provides a simple Go application to get the size of the terminal.

This package implements functionality for reading the unique machine ID (/etc/machine-id) of most OSs (without admin privileges).

Package uuid provides implementations of the Universally Unique Identifier (UUID), as specified in RFC-4122 and the Peabody RFC Draft (revision 03).

This package provides a structured event logger for Golang developed for fluentd.

This is a development helper program that generates a Golang interface by inspecting the structure methods of an existing .go file. The primary use case is to generate interfaces for gomock, so that gomock can generate mocks from those interfaces.

Package term manages POSIX terminals. As POSIX terminals are connected to, or emulate, a UART, this package also provides control over the various UART and serial line parameters.

This provides helper functions for dealing with signals across various operating systems.

Go Windows Service wrapper compatible with GNU/Linux. Windows tests here.
