Review RegexBuddy

A new buddy for you

Have you ever tried using regular expressions while programming but always wondered: “How can I try this without risking my code and still make sure it does what I want?” Have you created auxiliary programs just to test regular expressions to avoid compiling over and over again in your main project? Or maybe you heard about regular expressions and are just curious about how they work? Well, if this describes you in any way, RegexBuddy will be your perfect buddy! And the best part is that you do not need any programming experience.

Nowadays, regular expressions (also known as regex) are a powerful tool for manipulating data and text; they are standard features in a wide range of programming languages and popular tools. However, it can sometimes be difficult to create or understand these patterns considering that its syntax can change depending on the programming language you are using. With RegexBuddy you will be able to create regular expressions that match your needs, test them on sample files without risking your data, and debugging them in just a few steps. But not only that, the tool will also be a helpful tool in expanding your understanding of regex written by others, while also improving your own regex!

How does your buddy operate?

This program is used for writing and debugging regular expressions. While typing your regex, the program builds a detailed English-language analysis, which is very convenient for understanding other people's regular expressions. This analysis is helpful in learning how your regex work and why they might not work in your code. You can just copy-paste your regular expression and the tool will tell you not only what regular expression you have to use but will also let you step through it and run it through some test data. All in real time. It will highlight all possible matches as you type!

RegexBuddy also includes a library with pre-created regular expressions on which you can rely. It includes a wide variety of tasks; all of them clearly described which could help you achieve whatever you are attempting. In addition, you can build your own library of regular expressions and use them whenever you desire, like your very own glossary of regex. Your amazing new Buddy also offers a built-in regex history, which allows users to compare the effects of different variations of a regular expression and allows them to work with more than one regex at a time.

Still there is more!

As if that were not good enough, it includes a GREP panel (similar to the ones in Linux) that allows you to search (and even replace) through files, folders and subfolders meaning that you can test your regex on a large number of files!

The action of a regular expression can be checked immediately on the desired text fragment or file. After debugging, you can save the regular expression in C#, Delphi, Java, JavaScript, PCRE, Perl, PHP, Python, REALbasic, Ruby, VB6 & VB.NET, VBScript and many other languages.

Your Buddy's Forum

Are you still not sure if you will be able to create your own regular expressions? Do not worry about it, RegexBuddy has a forum where you can submit your regex for feedback from other users, ask questions or see how others solved their issues. The forum is an excellent tool for exchanging ideas on how to implement regular expressions with whatever application or programming language you work with. So, if you get stuck, ask away and someone will be there to help you!

The program runs on Windows 98, ME, 2000, XP, Vista, 7, and 8. Unfortunately, for Linux and Apple users it is still not available though, but it runs well on VMware, Parallels, and CrossOver Office.
