Then select Search|Multiline Search Panel in the menu. EditPad Pro’s regex engine is fully functional in the demo version.Īs a quick test, copy and paste the text of this page into EditPad Pro.

If you do not have such an editor, you can download the free evaluation version of EditPad Pro to try this out.

You can easily try the following yourself in a text editor that supports regular expressions, such as EditPad Pro. Even if your application is not explicitly covered by the tutorial, it likely uses a regex flavor that is covered, as most applications are developed using one of the programming environments or regex libraries just mentioned. The tutorial alerts you when these flavors require different syntax or show different behavior. NET, Java, JavaScript, XRegExp, VBScript, Python, Ruby, Delphi, R, Tcl, POSIX, and many others. This tutorial covers all the popular regular expression flavors, including Perl, PCRE, PHP. The syntax and behavior of a particular engine is called a regular expression flavor.

Rather, the application invokes it for you when needed, making sure the right regular expression is applied to the right file or data.Īs usual in the software world, different regular expression engines are not fully compatible with each other. Usually, the engine is part of a larger application and you do not access the engine directly. Different Regular Expression EnginesĪ regular expression “engine” is a piece of software that can process regular expressions, trying to match the pattern to the given string. In practice, you can use regular expressions with whatever data you can access using the application or programming language you are working with. The term “string” or “character string” is used by programmers to indicate a sequence of characters. This tutorial uses the term “string” to indicate the text that the regular expression is applied to. With the above regular expression pattern, you can search through a text file to find email addresses, or verify if a given string looks like an email address. You’ll see additional colors like green for grouping and purple for meta tokens later in the tutorial.

Word boundaries and quantifiers are blue, character classes are orange, and escaped literals are gray. This also shows the syntax highlighting applied to regular expressions on this site. In other words: this pattern describes an email address.

It describes a series of letters, digits, dots, underscores, percentage signs and hyphens, followed by an at sign, followed by another series of letters, digits and hyphens, finally followed by a single dot and two or more letters. Matches are highlighted in blue on this site.

A “match” is the piece of text, or sequence of bytes or characters that pattern was found to correspond to by the regex processing software. It is the most basic pattern, simply matching the literal text regex. This first example is actually a perfectly valid regex. On this website, regular expressions are shaded gray as regex. This tutorial uses "regex", because it is easy to pronounce the plural "regexes". You will usually find the name abbreviated to "regex" or "regexp". Their name comes from the mathematical theory on which they are based. What Regular Expressions Are Exactly - Terminologyīasically, a regular expression is a pattern describing a certain amount of text. It will save you lots of guesswork and head scratching when you need to write more complex regexes. This helps you to quickly understand why a particular regex does not do what you initially expected. It also explains how a regular expression engine works on the inside and alerts you to the consequences. 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. This tutorial teaches you all you need to know to be able to craft powerful time-saving regular expressions.
