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. One line of code per option is all you need to write.
For that, you get a nice automatically-generated help page, robust option
parsing, command subcompletion, and sensible defaults for everything you don't
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.
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!
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
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.
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.
