Regular Expression Tutorial - Learn How to Use Regular Expressions This tutorial teaches you all you need to know to be able to craft powerful time-saving regular expressions. It starts with the most basic concepts, so that you can follow this tutorial even if you know nothing at all about regular expressions yet. The tutorial doesn't stop there. It also explains how a regular expression engine works on the inside, and alert you at the consequences. Rails Beginner Cheat Sheet Bold words are what is really important e.g. the command and concept shown in the usage category. In the code usage and example columns these highlight the main part of the concept, like this: general_stuff.concept. In the same columns italic_words mark the arguments/parameters of a command/method. However italic words in the descriptions or general text denote more general concepts or concepts explained elsewhere in this cheat sheet or in general. The console (also called command line, command prompt or terminal) is just another way of interacting with your computer.
Tracker Basics - GHOSTERY Chances are, you visit a huge array of different websites every day. What you might not know is that while you do that, there is an “invisible web” at work: companies are following your activities, collecting your data, and using it in various ways. They do it through technology known as “trackers.” Python Regular Expressions - Educational Materials Regular expressions are a powerful language for matching text patterns. This page gives a basic introduction to regular expressions themselves sufficient for our Python exercises and shows how regular expressions work in Python. The Python "re" module provides regular expression support. In Python a regular expression search is typically written as: match = re.search(pat, str) The re.search() method takes a regular expression pattern and a string and searches for that pattern within the string.
.NET Framework Regular Expressions Regular expressions provide a powerful, flexible, and efficient method for processing text. The extensive pattern-matching notation of regular expressions enables you to quickly parse large amounts of text to find specific character patterns; to validate text to ensure that it matches a predefined pattern (such as an e-mail address); to extract, edit, replace, or delete text substrings; and to add the extracted strings to a collection in order to generate a report. For many applications that deal with strings or that parse large blocks of text, regular expressions are an indispensable tool. The centerpiece of text processing with regular expressions is the regular expression engine, which is represented by the System.Text.RegularExpressions.Regex object in the .NET Framework.
Writing programs using ordinary language In a pair of recent papers, researchers at MIT’s Computer Science and Artificial Intelligence Laboratory have demonstrated that, for a few specific tasks, it’s possible to write computer programs using ordinary language rather than special-purpose programming languages. The work may be of some help to programmers, and it could let nonprogrammers manipulate common types of files — like word-processing documents and spreadsheets — in ways that previously required familiarity with programming languages. But the researchers’ methods could also prove applicable to other programming tasks, expanding the range of contexts in which programmers can specify functions using ordinary language. “I don’t think that we will be able to do this for everything in programming, but there are areas where there are a lot of examples of how humans have done translation,” says Regina Barzilay, an associate professor of computer science and electrical engineering and a co-author on both papers.
8 Regular Expressions You Should Know Regular expressions are a language of their own. When you learn a new programming language, they're this little sub-language that makes no sense at first glance. Many times you have to read another tutorial, article, or book just to understand the "simple" pattern described.

What every programmer absolutely, positively needs to know about encodings and character sets to work with text — kunststube.net If you are dealing with text in a computer, you need to know about encodings. Period. Yes, even if you are just sending emails. Even if you are just receiving emails. You don't need to understand every last detail, but you must at least know what this whole "encoding" thing is about.
