Raleigh, NC—A GUI application isn't always the best solution: with its simple commands, flags, and parameters, a well-formed command-line application is the quickest way to automate a backup, a build, or a deployment and simplify your life.
In Build Awesome Command-Line Applications in Ruby (Pragmatic Bookshelf, $33.00) Ruby pro David Copeland explains how to write a command-line application that is self-documenting, robust, adaptable and forever useful. It's 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.
Available in epub, mobi, and PDF direct from the publisher and in paperback from fine bookstores worldwide.
