This package implements a functionality for creating, managing, inspecting, and destroying cgroups. The resources format for settings on the cgroup uses the OCI runtime-spec found here.

cpuid provides information about the CPU running the current program. CPU features are detected on startup, and kept for fast access through the life of the application. Currently x86 / x64 (AMD64) is supported, and no external C (cgo) code is used, which should make the library very eas to use.

Package pgservicefile is a parser for PostgreSQL service files (e.g. .pg_service.conf).

Ristretto is a concurrent, fixed size, in-memory cache with a dual focus on throughput and hit ratio performance.

This package provides the Windows API used at Charmbracelet.

This package provides a pretty-printer for Go. The functions defined by pp follow an API similar to fmt and its configuration can be customized globally.

The bom package provides small tools for cleaning BOMs from a byte array or reader.

This package provides a text formatting functions in Go.

This package provides a wrapper around go-yaml designed to enable a better way of handling YAML when marshaling to and from structs.

This package provides a library for BOM detection.

Package reedsolomon enables Erasure Coding. It's a Go port of the JavaReedSolomon.

For encoding high shard counts (>256) a Leopard implementation is used. For most platforms this performs close to the original Leopard implementation in terms of speed.

Package goldie provides test assertions based on golden files. It's typically used for testing responses with larger data bodies.

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

This package provides a basic system stats like DiskUsage and MemoryInfo.

Readline is a pure Go implementation of a GNU-Readline like library.

The package Expr provides a Go-centric expression language designed to deliver dynamic configurations with unparalleled accuracy, safety, and speed.

term provides an API for working with terminals that includes:

• Switching a terminal to the raw mode.

• Getting, setting and restoring the state of a terminal.

• Getting size of a terminal.

• Reading passwords from a terminal without a local echo.

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

clipboard provides copying and pasting to the clipboard for Go.

This package implements functionality to map HCL or JSON fragment into Golang structs.

Package uilive provides a writer that live updates the terminal. It provides a buffered io.Writer that is flushed at a timed interval.

This package provides a toolkit for logging that is both human and machine readable. It is modeled after the Go standard library's io and net/http packages and is an alternative to the standard library's log package.
