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 provides an implementation of JSON5.

This package is a wrapper around each of the the Unicode-version-specific textseg implementations that selects an implementation automatically based on the Unicode version of the Go standard library that it's being built against.

This package provides a pure Go implementation of functionality comparable to GNU Readline, i.e. line editing and command history for simple TUI programs.

Package vaxis is a terminal user interface for modern terminals. It supports supports modern terminal features, such as styled underlines and graphics. A widgets package is provided with some useful widgets.

Package btclog defines a logger interface and provides a default implementation of a subsystem-aware leveled logger implementing the same interface.

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

This package is a simple exponential backoff counter in Go.

This package provides decoding of basic EXIF and TIFF encoded data. Functionality is split into packages:

• exif - implements decoding of EXIF data as defined in the EXIF 2.2 specification (http://www.exif.org/Exif2-2.PDF)

• mknote - provides makernote parsers that can be used with goexif/exif

• tiff - implements TIFF decoding as defined in TIFF 6.0 specification at http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf

The flags package provides a command line option parser. The functionality is similar to the go builtin flag package, but flags provides more options and uses reflection to provide a succinct way of specifying command line options.

This package provides a library for building powerful interactive prompts inspired by python-prompt-toolkit, making it easier to build cross-platform command line tools using Go.

Package deque provides a fast ring-buffer deque (double-ended queue) implementation for Golang.

It generalizes a queue and a stack, to efficiently add and remove items at either end with O(1) performance. Queue (FIFO) operations are supported using PushBack and PopFront. Stack (LIFO) operations are supported using PushBack and PopBack.

Package btrfs provides bindings for working with btrfs partitions from Go. The Linux kernel headers are only required on compilation time, not on run time.

Package sortedset provides the data-struct allowing a fast access the element in set by key or by score(order). It is inspired by Sorted Set from Redis.
