glg is simple lock-free logging library for Go.

deepcopy implements a functionality of deep copies of things. A standard copy will copy the pointers where deepcopy copies the values pointed to. Unexported field values are not copied.

This package provides Protocol Buffer models and associated libraries for working with API description formats supported by gnostic. It exists to provide a lightweight distribution of these models with minimal dependencies.

Goof (Go Object Finder) is a package that does the unthinkable to the binaryes: calling functions, fmt.Fprintf, and accesing reflect.Type from them.

This package provides ANSI colors for Golang. The package supports Printf/Sprintf etc.

This package provides a library for embedding human-meaningful graphics in QR codes. However, instead of scribbling on redundant pieces and relying on error correction to preserve the meaning, qart engineers the encoded values to create the picture in a code with no inherent errors.

Package errors provides errors that have stack-traces. It provides the type *Error which implements the standard golang error interface, so you can use this library interchangeably with code that is expecting a normal error return.

This package is a Go library that draws progress bars on the terminal.

Package filepathx adds double-star globbing support to the Glob function from the core path/filepath package. You might recognize "**" recursive globs from things like your .gitignore file, and zsh. The "**" glob represents a recursive wildcard matching zero-or-more directory levels deep.

copystructure is a Go library for deep copying values in Go.

This allows you to copy Go values that may contain reference values such as maps, slices, or pointers, and copy their data as well instead of just their references.

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.

This package provides ioctl wrapper to std syscall and os.

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

Package pretty provides pretty-printing for Go values. This is useful during debugging, to avoid wrapping long output lines in the terminal.

It provides a function, Formatter, that can be used with any function that accepts a format string. It also provides convenience wrappers for functions in packages fmt and log.

This package provides implementation of MessagePack encoding for Go programming language.

Puddle is a tiny generic resource pool library hat uses the standard context library to signal cancellation of acquires. It is designed to contain the minimum functionality required for a resource pool. It can be used directly or it can be used as the base for a domain specific resource pool. For example, a database connection pool may use puddle internally and implement health checks and keep-alive behavior without needing to implement any concurrent code of its own.

Package vfs provides an abstraction of the os and ioutil packages that is easy to test.

go-semver is a semantic versioning library for Go. It lets you parse and compare two semantic version strings.

This package implements a deep pretty printer for Go data structures to aid data snapshotting.

This package provides an implementation of the Unicode Text Segmentation specification for Go. Specifically, it currently includes only the grapheme cluster segmentation algorithm.

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

This package provides a simple TUN/TAP interface library for Go that efficiently works with standard packages like io, bufio, etc.. Use waterutil with it to work with TUN/TAP packets/frames.

This package implements Go types for over 70 PostgreSQL types. It is the type system underlying the https://github.com/jackc/pgx PostgreSQL driver. These types support the binary format for enhanced performance with pgx. They also support the database/sql Scan and Value interfaces and can be used with https://github.com/lib/pq.

This package implements a simple XML 1.0 parser that understands XML name spaces, along with extended support for control characters.
