nscjar is a Go library used to parse and output Netscape/Mozilla's old-style cookie files. It also implements a simple cookie jar struct to manage the cookies added to the cookie jar.
cli is a simple, fast, and fun package for building command line apps in Go. The goal is to enable developers to write fast and distributable command line applications in an expressive way.

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
Go-Logging implements a logging infrastructure for Go. Its output format is customizable and supports different logging backends like syslog, file and memory. Multiple backends can be utilized with different log levels per backend and logger.
pkcs8 implements functions to process private keys in PKCS#8 format, as defined in RFC 5208 and RFC 5958. It can handle both unencrypted PKCS#8 PrivateKeyInfo format and EncryptedPrivateKeyInfo format with PKCS#5 (v2.0) algorithms.
Package queue provides a fast, ring-buffer queue based on the version suggested by Dariusz Górecki. Using this instead of other, simpler, queue implementations (slice+append or linked list) provides substantial memory and time benefits, and fewer GC pauses.
go-github-com-gosuri-uilive go library for updating terminal output in realtime. It provides a buffered io.Writer that is flushed at a timed interval. go-github-com-gosuri-uilive powers go-github-com-gosuri-uiprogress.
This package provides a Golang web framework wit martini-like API.
Features:
zero allocation router
middleware support
crash-free
JSON validation
routes grouping
error management
rendering built-in
extendable
Correct is a collection of assertion libraries for Golang, intended to be used together. It tries not to strictly enforce that, though - most of correct should be customizeable either by changing some options or by using only some sub-packages of correct.
The Common Expression Language (CEL) is a non-Turing complete language designed for simplicity, speed, safety, and portability. CEL's C-like syntax looks nearly identical to equivalent expressions in C++, Go, Java, and TypeScript.
This package is a UPnP DLNA Digital Media Server. It runs from the terminal, and serves content directly from the filesystem from the working directory, or the path given. The SSDP component will broadcast and respond to requests on all available network interfaces.
Mage is a make-like build tool using for Go. It implements a functionality of writing plain-old go functions which Mage automatically uses as Makefile-like runnable targets consistent across a project. This package provides a source library and built command mage.
Deck is a library for clients to make scalable presentations, using a standard markup language. Clients read deck files into the Deck structure, and traverse the structure for display, publication, etc. Clients may be interactive or produce standard formats such as SVG or PDF.
The goxpp library, inspired by Java's XML, is a lightweight wrapper for Go's standard XML Decoder,tailored for developers who need fine-grained control over XML parsing.
This package is an enhanced version of the golang.org/x/image/tiff library featuring:
Read support for CCITT Group3/4 compressed images.
Read/write support for LZW compressed images.
Read/write support for the CMYK color model.
Package log implements a std log compatible logging system that draws some inspiration from the Python logging module from Python's standard library. It supports multiple handlers, log levels, zero-allocation, scopes, custom formatting, and environment and runtime configuration.
This package aims to provide algorithms optimized to leverage advanced instruction sets of modern CPUs to maximize throughput and take the best advantage of the available compute power. It includes functions that have often been designed to work on arrays of values, which is where SIMD and branchless algorithms shine.
This package implements a functionality to converts Go values at runtime into their @codego/ast equivalent,which may be used in debugging and testing, as a more comprehensive and configurable version of the fmt package's %+v and %#v formatting directives. It is similar to e.g. repr in Python.
A mini testing helper for Go.
It has a simple interface (
is.OKandis.Equal).It plugs into existing Go toolchain (uses
testing.T).It's obvious for newcomers.
It also gives you
is.Panicandis.PanicWithhelpers - because testing panics is ugly.
Gocc is a compiler kit for Go written in Go. Gocc generates lexers and parsers or stand-alone DFAs or parsers from a BNF. Lexers are DFAs, which recognise regular languages. Gocc lexers accept UTF-8 input. Gocc parsers are PDAs, which recognise LR-1 languages. Optional LR1 conflict handling automatically resolves shift / reduce and reduce / reduce conflicts.
Package pflag is a drop-in replacement for Go's flag package, implementing POSIX/GNU-style --flags. It is compatible with the GNU extensions to the POSIX recommendations for command-line options. This is an actively maintained fork of https://github.com/ogier/pflag.
ll is a high-performance, production-ready logging library for Go, designed to provide hierarchical namespaces, structured logging, middleware pipelines, conditional logging, and support for multiple output formats, including text, JSON, colorized logs, and compatibility with Go’s slog. It’s ideal for applications requiring fine-grained log control, extensibility, and scalability.
A minimal QPACK (RFC 9204) implementation in Go. It is minimal in the sense that it doesn't use the dynamic table at all, but just the static table and (Huffman encoded) string literals. Wherever possible, it reuses code from the HPACK implementation in the Go standard library.
