Package stringprep provides data tables and algorithms for RFC-3454, including errata. It also provides a profile for SASLprep as defined in RFC-4013.

This package implements a functionality to modify/update field tags in structs making it easy to update, add or delete the tags in a struct field with possibility to add and remove tag options. It's intended to be used by an editor, but also has modes to run it from the terminal. This package provides a command line interface (CLI) tool.

This package implements a functionalit to list currently running Go processes.

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

go-diff offers algorithms to perform operations required for synchronizing plain text:

• compare two texts and return their differences

• perform fuzzy matching of text

• apply patches onto text

Diskv (disk-vee) is a simple, persistent key-value store written in the Go language. It starts with a simple API for storing arbitrary data on a filesystem by key, and builds several layers of performance-enhancing abstraction on top. The end result is a conceptually simple, but highly performant, disk-backed storage system.

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.

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 set of parsing tools for Go inspired by Sprache.

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.

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.

mtree is a filesystem hierarchy validation tooling and format. This is a library and simple CLI tool for mtree(8) implemented in Go.

This package provides functionality to load functions used in Sonic JSON library.

Package logr defines a general-purpose logging API and abstract interfaces to back that API. Packages in the Go ecosystem can depend on it, while callers can implement logging with whatever backend is appropriate.

flock implements a thread-safe file lock. It also includes a non-blocking TryLock function to allow locking without blocking execution.

Package fastuuid provides UUID generation of 192 bit universally unique identifiers. It also provides simple support for 128-bit RFC-4122 V4 UUID strings.

This package provides provides an utility for timezone manipulation, implementing the following features:

• this library uses only the standard package

• supports getting offset from timezone abbreviation, which is not supported by the time package

• determine whether the specified time.Time is daylight saving time

• change the location of time.Time by specifying the timezone

This package implements functionality to format Assembler code the same way that gofmt formats Go code.

This package provides a reporter for the go-metrics library which posts metrics to Graphite.

This package provides a encoder and decoder of the PostgreSQL wire protocol version 3.

This package provides set of utilities/abstractions developed as part of datastore connectivity and testing (viant/dsc, viant/dsunit).

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

This package provides a set of libraries that implementing low-level, kubernetes-independent packages supplementing the Go standard libs.

Package fx is a framework that makes it easy to build applications out of reusable, composable modules.
