This package provides a functionality for cross-platform locale detection.

Package templatecheck checks Go templates for problems. It can detect many errors that are normally caught only during execution. Use templatecheck in tests to find template errors early, and along template execution paths that might only rarely be reached.

This package provides factors out an opinionated selection of internal packages and functionality from the Go standard library. Currently this consists mostly of packages and testing code from within the Go tool implementation.

Included are the following:

• dirhash: calculate hashes over directory trees the same way that the Go tool does.

• goproxytest: a GOPROXY implementation designed for test use.

• gotooltest: Use the Go tool inside test scripts (see testscript below)

• imports: list of known architectures and OSs, and support for reading import import statements.

• modfile: read and write go.mod files while preserving formatting and comments.

• module: module paths and versions.

• par: do work in parallel.

• semver: semantic version parsing.

• testenv: information on the current testing environment.

• testscript: script-based testing based on txtar files

• txtar: simple text-based file archives for testing.

This pacakge provides bindings for CRIU. The code is based on the Go-based PHaul implementation from the CRIU repository.

This package provides basic image processing functions (resize, rotate, crop, brightness/contrast adjustments, etc.).

Multi-log is based on logrus, and supports concurrently logging to two destinations: the console and a log file.

Package protect is a wrapper for OpenBSD's pledge and unveil system calls.

It allows one to safely call Unveil / Pledge on non-OpenBSD operating systems.

This package provides simple wrappers for primitive types to enforce atomic access.

This is a Go library for detecting the user's home directory without the use of cgo, so the library can be used in cross-compilation environments.

Usage is simple, just call homedir.Dir() to get the home directory for a user, and homedir.Expand() to expand the ~ in a path to the home directory.

Why not just use os/user? The built-in os/user package requires cgo on Darwin systems. This means that any Go code that uses that package cannot cross compile. But 99% of the time the use for os/user is just to retrieve the home directory, which we can do for the current user without cgo. This library does that, enabling cross-compilation.

Package opt implements command-line flag parsing.

Package sqlstruct provides some convenience functions for using structs with the Go standard library's database/sql package.

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 provides a basic set of functions applying grammar rules to inflect English words, modify case style (Capitalize, camelCase, snake_case, etc.).

This package provides functionality to generate Go code.

This library provides caching capabilities for Go with no garbage collection overhead and high concurrent performance. An unlimited number of objects can be cached in memory without increased latency or degraded throughput.

Package zerolog provides a lightweight logging library dedicated to JSON logging.

This package provides a simple way to create a system service.

The uri package implements the URI Uniform Resource Identifier (RFC3986) specification in Go.

This package provides a way to attach key/value annotations to a Go context.Context.

This package provides INI file read and write functionality in Go.

Open a file, directory, or URI using the OS's default application for that object type. Optionally, you can specify an application to use. On GNU/Linux, this is a proxy for the xdg-open command.

This package provides a pretty printer for Go values.

This package provides a Go library for reading from continuously updating files, like tail -f.

Blackfriday is a Markdown processor in Go.
