In plain words

Regular Expression Compilation Visualized is an interactive tool that shows how regular expressions are processed and compiled. It breaks down the step-by-step transformation of regex patterns into executable form, making the technical process visible and easier to understand. The tool is designed for developers, students, and anyone learning about regular expressions who wants to see the internal mechanics behind pattern matching rather than just using regex as a black box.

    An extension of regular expressions for text editing, with a grep-like command-line tool. If you, like me, struggle with group logic in regular expressions, you might find it useful. I wanted to do this for a very long time. It is more of a sketch or prototype. I'd really appreciate your feedback!
