Book Description
Text is everywhere. Web pages, databases, the contents of files--for almost any programming task you perform, you need to process text. Cut even the most complex text-based tasks down to size and learn how to master regular expressions, scrape information from Web pages, develop reusable utilities to process text in pipelines, and more. Most information in the world is in text format, and programmers often find themselves needing to make sense of the data hiding within. It might be to convert it from one format to another, or to find out information about the text as a whole, or to extract information fromit. But how do you do this efficiently, avoiding labor-intensive, manual work? Text Processing with Ruby takes a practical approach. You'll learn how to get text into your Ruby programs from the file system and from user input. You'll process delimited files such as CSVs, and write utilities that interact with other programs in text-processing pipelines. Decipher character encoding mysteries, and avoid the pain of jumbled characters and malformed output. You'll learn to use regular expressions to match, extract, and replace patterns in text. You'll write a parser and learn how to process Web pages to pull out information from even the messiest of HTML. Before long you'll be able to tackle even the most enormous and entangled text with ease, scything through gigabytes of data and effortlessly extracting the bits that matter. What You Need: This book requires a passing familiarity with the Ruby programming language, and assumes that you already have Ruby installed on your computer.

Book Description
"Whatever you want to do with text, Ruby is up to the job. Most information in the world is in text format, and you need to make sense of the data hiding within. You want to do this efficiently, avoiding labor-intensive, manual work. Text Processing with Ruby takes a practical approach to working with text. First, Aquire: Explore Ruby's core and standard library, and extract text into your Ruby programs. Process delimited files and web pages, and write utilities. Second, Transform: Use regular expressions, write a parser, and use Natural Language Processing techniques. Finally, Load: Write the transformed text and data to standard output, files, and other processes. Serialize text into JSON, XML, and CVS, and use ERB to create more complex formats. You'll soon be able to tackle even the most enormous and entangled text with ease."--Back cover.

Book Description
An expert guide to Ruby, a popular new Object-Oriented Programming LanguageRuby is quickly becoming a favourite among developers who need a simple, straight forward, portable programming language. Ruby is ideal for quick and easy object-oriented programming such as processing text files or performing system management. Having been compared with other programming languages such as Perl, Python, PCL, Java, Eiffel, and C++; Ruby is popular because of its straight forward syntax and transparent semantics.Using step-by-step examples and real world applications, the Ruby Developer's Guide is designed for programmers and developer's looking to embrace the object-oriented features and functionality of this robust programming language. Readers will learn how to develop, implement, organize and deploy applications using Ruby. - Ruby is currently experiencing a rapid rise in popularity in the object-oriented programming community - Readers receive up-to-the minute links, white papers, and analysis for two years at

Book Description
You might think of regular expressions as the holy grail of text processing, but are you sure you aren't just shoehorning them in where standard built-in solutions already exist and would work better? JavaScript itself provides programmers with excellent methods for text manipulation, and knowing how and when to use them will help you write more efficient and performant code. From extracting data from APIs to calculating word counts and everything in between, discover how to pick the right tool for the job and make the absolute most of it every single time. Whether you're a beginner or an advanced programmer, this up-to-date guide will save you a ton of time when dealing with text. With Text Processing with JavaScript, you'll find a collection of tiny programs, each demonstrating a string manipulation approach in JavaScript. You'll also focus squarely on the practical aspects of text processing with JavaScript - that is, what each technique is designed to accomplish and how to use it in your program. Discover how to extract data from APIs and web pages, apply spelling corrections, convert and format currencies, and remove HTML tags from text. Learn to intersect tables, copy text to the clipboard, extract lists from text, and highlight sentences that contain a specific word. Find duplicate words and fix them automatically, modify a copy of an existing regex literal, match the beginning or end of a string, and remove all comments from JavaScript and HTML files with ease. Match non-ASCII words, calculate the word count of an article in any language, and more. Become a JavaScript expert and master chef of text processing with this collection of hands-on and production-ready recipes.
