OptionParser based CLI support for rapid CLI development in an object-oriented context. This library wraps Ruby's OptionParser for parsing your options under the hood, so you get all the goodness that the Ruby standard library provides. On top of that it adds a rich and powerful DSL for definin...

A simple mixin for CLI interfaces, including option parsing

A DSL for gathering options and parsing command line flags

Cri allows building easy-to-use command-line interfaces with support for subcommands.

The complete solution for Ruby command-line executables. Commander bridges the gap between other terminal related libraries you know and love (OptionParser, HighLine), while providing many new features, and an elegant API.

Clamp provides an object-model for command-line utilities. It handles parsing of command-line options, and generation of usage help.

A high-level IO library that provides validation, type conversion, and more for command-line interfaces. HighLine also includes a complete menu system that can crank out anything from simple list selection to complete shells with just minutes of work.

Trollop is a commandline option parser for Ruby that just gets out of your way. **DEPRECATION** This gem has been renamed to optimist and will no longer be supported. Please switch to optimist as soon as possible.

Methadone provides a lot of small but useful features for developing a command-line app, including an opinionated bootstrapping process, some helpful cucumber steps, and some classes to bridge logging and output into a simple, unified, interface

cmdparse provides classes for parsing (possibly nested) commands on the command line; command line options themselves are parsed using optparse.

The getopt library provides two different command line option parsers. They are meant as easier and more convenient replacements for the command line parsers that ship as part of the Ruby standard library. Please see the README for additional comments.

Command-line arguments to hash

A small library for doing (command) lines

Isn't it awesome how `optparse` and other option parsers generate help and usage-messages based on your code?! Hell no! You know what's awesome? It's when the option parser *is* generated based on the help and usage-message that you write in a docstring! That's what docopt does!

Choice is a simple little gem for easily defining and parsing command line options with a friendly DSL.

It's just here to handle arguments provided to Application. Mainly optional via switches. Currently handles plain-text Console arguments.

This is an lightweight option parser, which is less than 80 lines short. It has strong validations and a short, clear and easy to use syntax. Feel free to copy all 80 lines (55 lines without validations / empty lines) into your script rather installing the gem.

Command-line option parser and command interface.

Clap is a small library that can be bundled with your command line application. It covers the simple case of executing code based on the flags or parameters passed.
