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

This package provides a command-line completion engine for the Kong CLI parser.

This package implements optimal parameters for data-types.

Multi-log is based on logrus, and supports concurrently logging to two destinations: the console and a log file.

This package implements a feature of limiting the maximum number of concurrently started routines which has the same role and API as sync.WaitGroup. It could for example be used to start multiples routines querying a database but without sending too much queries in order to not overload the given database.

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