This package produces a collection of cryptographic utilities, including the following:

• drbg: a cryptographically secure pseudorandom number generator as specified in NIST SP 800-90A

• encoding/base32: a compact base32 encoder

• secretkey: user-friendly secret keys that can be used with secretbox

• salsa20: a streaming interface (cipher.Stream) for the Salsa20 stream cipher

• poly1305: a streaming interface (hash.Hash) for the Poly1305 one-time authenticator as specified in poly1305

This is a Go library for detecting the user's home directory without the use of cgo, so the library can be used in cross-compilation environments.

Usage is simple, just call homedir.Dir() to get the home directory for a user, and homedir.Expand() to expand the ~ in a path to the home directory.

Why not just use os/user? The built-in os/user package requires cgo on Darwin systems. This means that any Go code that uses that package cannot cross compile. But 99% of the time the use for os/user is just to retrieve the home directory, which we can do for the current user without cgo. This library does that, enabling cross-compilation.

This package implements a functionality which can be used in instrument code, expose application metrics, and profile runtime performance in a flexible manner. It makes use of a MetricSink interface to support delivery to any type of backend.

Currently the following sinks are provided:

• StatsiteSink : Sinks to a statsite instance (TCP)

• StatsdSink: Sinks to a StatsD / statsite instance (UDP)

• PrometheusSink: Sinks to a Prometheus metrics endpoint (exposed via HTTP for scrapes)

• InmemSink : Provides in-memory aggregation, can be used to export stats

• FanoutSink : Sinks to multiple sinks. Enables writing to multiple statsite instances for example

• BlackholeSink : Sinks to nowhere

This package provides factors out an opinionated selection of internal packages and functionality from the Go standard library. Currently this consists mostly of packages and testing code from within the Go tool implementation.

Included are the following:

• dirhash: calculate hashes over directory trees the same way that the Go tool does.

• goproxytest: a GOPROXY implementation designed for test use.

• gotooltest: Use the Go tool inside test scripts (see testscript below)

• imports: list of known architectures and OSs, and support for reading import import statements.

• modfile: read and write go.mod files while preserving formatting and comments.

• module: module paths and versions.

• par: do work in parallel.

• semver: semantic version parsing.

• testenv: information on the current testing environment.

• testscript: script-based testing based on txtar files

• txtar: simple text-based file archives for testing.
