RegexBuddy’s Detailed Tutorial on Regular Expressions

Learn all there is to know about regular expressions today with RegexBuddy's detailed, step by step regular expression tutorial. When you buy RegexBuddy, you get the tutorial both as a help file that you can read on your computer, and as a PDF file that you can print.

You will learn each of the different elements that compose a regular expression, step by step in logical order. If you already have some experience with regular expressions, this logical separation enables you to brush up your knowledge on specific areas. When trying to understand a regex, you only need to click the Explain Token button, and RegexBuddy will present you the appropriate topic in the tutorial.

Remember that you don't need any programming experience to learn and benefit from regular expressions. A lot of software these days allows you to use regular expressions when searching through or filtering text.

If you are a programmer, the language reference in RegexBuddy's documentation provides a handy summary how to implement regular expressions. The reference often points out small but important details that you don't find in the documentation that comes with the development tools or libraries.

Languages covered include C#, C, C++, VB.NET, VB 6, Delphi, Java, Groovy, Perl, PHP, JavaScript, VBScript, Python, Ruby, Tcl, PowerShell, R, and more. Libraries covered include the Microsoft .NET framework, the open source library PCRE and the POSIX standard. Databases discussed include Oracle Database, MySQL and PostgreSQL.
