Pad( length, padding = "0")Pad strings or numbers with given characters ('0' by default). Pretty much 1x01, normalizing accents, and lots of other cleanup operations. You can find predefined format expressions for all kinds of scenarios in the forums. Which means that you can do pretty much anything, especially if you know a little bit about programming.

, the vertical bar or pipe symbol |, the question mark ?, the asterisk or star *, the plus sign +, the opening parenthesis (, the closing parenthesis ), the opening square bracket [, and the opening curly brace matches a single character that is not in the given Unicode category. Twelve characters have special meanings in regular expressions: the backslash \, the caret ^, the dollar sign $, the period or dot. In a programming language, there is usually a separate function that you can call to continue searching through the string after the previous match.
In a text editor, you can do so by using its “Find Next” or “Search Forward” function. It only does so when you tell the regex engine to start searching through the string after the first match. If the string is Jack is a boy, it matches the a after the J. It matches the first occurrence of that character in the string. The most basic regular expression consists of a single literal character, such as a.

On this website, regular expressions are shaded gray as regex. Text Patterns and MatchesĪ regular expression, or regex for short, is a pattern describing a certain amount of text. This quick start explains the syntax supported by the most popular regular expression flavors. When two applications use a different implementation of regular expressions, we say that they use different “regular expression flavors”. Many applications and programming languages have their own implementation of regular expressions, often with slight and sometimes with significant differences from other implementations. Each topic in the quick start corresponds with a topic in the tutorial, so you can easily go back and forth between the two. For detailed information, consult the regular expressions tutorial. Obviously, this brief introduction cannot explain everything there is to know about regular expressions. This quick start gets you up to speed quickly with regular expressions.
