go-opt is a library to parse command line arguments based on tag annotations on struct fields. It came as a spin-off from aerc to deal with its internal commands.

This package provides a Go library for handling a superset of semantic versioning.

Package borp provides a simple way to marshal Go structs to and from SQL databases. It uses the database/sql package, and should work with any compliant database/sql driver.

Tengo is a small, dynamic, fast, secure script language for Go. Features:

• higher-order functions and closures

• immutable values

• securely embeddable and extensible

• compiler/runtime written in native Go (no external deps or cgo)

• executable as a standalone language/REPL

• use cases: rules engine, state machine, data pipeline, transpiler

difflib is a simple library in Go for diffing two sequences of text.

Package klog implements logging analogous to the Google-internal C++ INFO/ERROR/V setup. It provides functions Info, Warning, Error, Fatal, plus formatting variants such as Infof. It also provides V-style logging controlled by the -v and -vmodule=file=2 flags. It's a is a permanent fork of https://github.com/golang/glog.

This package provides helpers to convert between pointers and values of built-in and, with generics, of any types.

This package provides a Julia grammar for tree-sitter bindings in Golang.

Package multicodec exposes the multicodec table as Go constants.

This package provides a implementation of the porter stemming algorithm: http://tartarus.org/~martin/PorterStemmer/index.html.

Package jcs transforms UTF-8 JSON data into a canonicalized version according @urlhttps://rfc-editor.org/rfc/rfc8785.html, RFC 8785.

lru is a package which implements a fixed-size thread safe Least recently used cache. It is based on the cache in Groupcache.

Package fwd provides a buffered reader and writer. Each has methods that help improve the encoding/decoding performance of some binary protocols.

Package reedsolomon enables Erasure Coding. It's a Go port of the JavaReedSolomon.

For encoding high shard counts (>256) a Leopard implementation is used. For most platforms this performs close to the original Leopard implementation in terms of speed.

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

Package channels provides a collection of helper functions, interfaces and implementations for working with and extending the capabilities of golang's existing channels. The main interface of interest is Channel, though sub-interfaces are also provided for cases where the full Channel interface cannot be met (for example, InChannel for write-only channels).

This package provides a simple error package with stack traces.

Package terminal is a vt10x terminal emulation backend, influenced largely by st, rxvt, xterm, and iTerm as reference. Use it for terminal muxing, a terminal emulation frontend, or wherever else you need terminal emulation.

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

Lumberjack is a Go package for writing logs to rolling files.

This package provides an easy access to native byte order.

Golden files (.golden) contain the raw expected output of tests,which can contain control codes and escape sequences. golden package provides an API for comparing Golden files.

PGV is a protoc plugin to generate polyglot message validators. While protocol buffers effectively guarantee the types of structured data, they cannot enforce semantic rules for values. This plugin adds support to protoc-generated code to validate such constraints. This package provides command line interface (CLI) tools.

bytebufferpool implements a pool of byte buffers with anti-fragmentation protection.
