About the Project

RegViz is a tool for debugging JavaScript regular expressions in a visual way. The goal of the project is to create a system to make regular expressions more readable. Advanced highlighting helps you to understand the structure and purpose of a regular expression and to detect bugs therein. You can test the regular expression on a sample text and formulate test cases. We tried to come up with a very user friendly tool.
