run.Group is a universal mechanism to manage goroutine lifecycles, written to manage component lifecycles in func main for OK Log. It's useful in any circumstance where you need to orchestrate multiple goroutines as a unit whole.

Helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.

Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).

This package provides a Go implementation of globs.

Package yaml can marshal and unmarshal cty values in YAML format.

Package script implements a small, customizable, platform-agnostic scripting language.

Package wincred provides primitives for accessing the Windows Credentials Management API. This includes functions for retrieval, listing and storage of credentials as well as Go structures for convenient access to the credential data.

This package implements an immutable radix tree. It only provides a single Tree implementation, optimized for sparse nodes.

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

This package implements Unicode Text Segmentation according to Unicode Standard Annex #29.

Package shell returns a user's shell across multiple platforms.

memory provides a single method reporting total physical system memory accessible to the kernel. It does not account for memory used by other processes.

This package provides the Windows API used at Charmbracelet.

Package ff is a flags-first helper package for configuring programs.

The basic idea is that myprogram -h should always show the complete configuration "surface area" of a program. Therefore, every config parameter should be defined as a flag. This module provides a simple and robust way to define those flags, and to parse them from command-line arguments, environment variables, and/or config files.

Package bolthold is an indexing and querying layer on top of a Bolt database. The goal is to allow easy, persistent storage and retrieval of Go types. BoltDB is an embedded key-value store, and bolthold servers a similar use case however with a higher level interface for common uses of BoltDB.

Billy implements an interface based on the OS's standard library to develop applications without depending on the underlying storage. This makes it virtually free to implement mocks and testing over file system operations.

Package colorprofile provides a way to downsample ANSI escape sequence colors and styles automatically based on output, environment variables, and Terminfo databases.

Package ring implements a FIFO queue backed by a ring buffer.

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.

Package slice provides utility functions for working with slices in Go.

Go-md2man is a Go program that converts markdown to roff for the purpose of building man pages.

This package provides a library for environment variables substitution.

GopherLua is a Lua5.1(+ goto statement in Lua5.2) VM and compiler. It provides Go APIs that allow you to easily embed a scripting language to your Go host programs.

Package bytesp is a plus to the standard bytes package.

This package provides a C99 compiler front end.
