cli is a library for implementing command-line interfaces. Features:

• easy sub-command based CLIs: cli foo, cli bar, etc.

• support for nested subcommands such as cli foo bar

• optional support for default subcommands so cli does something other than error

• support for shell autocompletion of subcommands, flags, and arguments with callbacks in Go

• automatic help generation for listing subcommands

• automatic help flag recognition of -h, --help, etc.

• automatic version flag recognition of -v, --version

• helpers for interacting with the terminal, such as outputting information, asking for input, etc.

• use of Go interfaces/types makes augmenting various parts of the library a piece of cake

Bolt is a pure Go key/value store inspired by Howard Chu's LMDB project. The goal of the project is to provide a simple, fast, and reliable database for projects that don't require a full database server such as Postgres or MySQL.

Package reservedpool implements a simple concurrency pool with per-category reservations. Each category of work can claim a number of slots that are reserved exclusively for it while any extra capacity is shared among all categories. This allows prioritizing certain categories without leaving the pool underutilized.

Acquire blocks until a slot for the requested category is available. Release returns a previously acquired slot. The pool can be closed to release waiters and reject future acquisitions.

Package randomstring can be used for generating different types of random strings.

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 sdnotify implements systemd readiness notifications as described in https://www.freedesktop.org/software/systemd/man/sd_notify.html.
