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

This package provides helpers for generating Go assembler ABI0 code.

Package expect provides an expect-like interface to automate control of applications. It is unlike expect in that it does not spawn or manage process lifecycle. This package only focuses on expecting output and sending input through it's psuedoterminal.

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 an implementation of JSON5.

This packages is fork of gopkg.in/yaml.v2 maintained by YAML organization.

This package implements optimal parameters for data-types.

This package is a very simple wrapper around log/syslog

Package zitadel/schema converts structs to and from form values. It is a maintained fork of https://github.com/gorilla/schema

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.

Cgofuse is a cross-platform FUSE library for Go. It is supported on multiple platforms and can be ported to any platform that has a FUSE implementation. It has cgo, !cgo (aka "nocgo") and FUSE (aka "FUSE2"), FUSE3 variants depending on the platform.

This package provides a fast gitignore matching library for Go.

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.

Go sigar is a golang implementation of the sigar API. The Go version of sigar has a very similar interface, but is being written from scratch in pure go/cgo, rather than cgo bindings for libsigar. This package provides an alternative fork of https://github.com/cloudfoundry/gosigar.

Package kyaml contains libraries for reading and writing Kubernetes Resource configuration as YAML.

This package provides traditional getopt processing for implementing programs that use traditional command lines.

This package provides the Windows API used at Charmbracelet.

This package provides a variable size buffer pool for Golang.

go-buffer-pool provides:

• BufferPool: A pool for re-using byte slices of varied sizes. This pool will always return a slice with at least the size requested and a capacity up to the next power of two. Each size class is pooled independently which makes the BufferPool more space efficient than a plain sync.Pool when used in situations where data size may vary over an arbitrary range.

• Buffer: a buffer compatible with bytes.Buffer but backed by a BufferPool. Unlike bytes.Buffer, Buffer will automatically shrink on read, using the buffer pool to avoid causing too much work for the allocator. This is primarily useful for long lived buffers that usually sit empty.

This package implements Swiss Tables as described in https://abseil.io/about/design/swisstables. It provides pseudo-randomized iteration (iteration order will change from one iteration to the next) and iteration stability akin to Go's builtin map if the map is mutated during iteration.
