As Ruby pro David Copeland explains, writing a command-line
application that is self-documenting, robust, adaptable and forever
useful is easier than you might think. Ruby is particularly suited
to this task, since it combines high-level abstractions with "close
to the metal" system interaction wrapped up in a concise, readable
syntax. Moreover, Ruby has the support of a rich ecosystem of
open-source tools and libraries. Ten insightful chapters each
explain and demonstrate a command-line best practice. You'll see
how to use these tools to elevate the lowliest automation script to
a maintainable, polished application. You'll learn how to use free,
open source parsers to create user-friendly command-line interfaces
as well as command suites. You'll see how to use defaults to keep
options simple for everyday users, while giving advanced users
options for more complex tasks. There's no reason a command-line
application should lack documentation, whether it's part of a help
command or a man page; you'll find out when and how to use both.
Your journey from command-line novice to pro ends with a look at
valuable approaches to testing your apps, and includes some fun
techniques for outside-the-box, colorful interfaces that will
delight your users. With Ruby, the command line is not dead. Long
live the command line. What You Need: All you'll need is Ruby, and
the ability to install a few gems along the way. Examples written
for Ruby 1.9.2, but 1.8.7 should work just as well.
