Regex Creator

Regex Creator is a Java-based application that allows web developers to create and test regular expressions.

It includes a simple set of configuration parameters.

Installation is not necessary, which makes Regex Creator portable.

You can drop the JAR file anywhere on the hard disk and run it, as well as move the program to a USB flash disk or similar storage unit, in order to run it on any machine that has Java installed.

What's more, the Windows registry does not get updated with new entries, and leftover files are not kept on the hard disk after removing the program.

The interface is represented by a regular window with a plain and simple layout, where you can write a text sample, create a group or delimiter from selection, add values, delete fields, generate regular expressions, as well as set the start position.

You can search for a regex pattern, debug regular expressions, disable case sensitive mode, as well as enable multi-line, among others.

Regex Creator does not put a strain on system performance, since it runs on a very low amount of CPU and RAM. We have not come across any problems throughout our evaluation, as the tool did not hang, crash or pop up error dialogs. Regex Creator serves its purpose.
