Learn Prolog Now! Enhanced is a Chrome add-on that aims to improve the user experience of the popular Prolog learning resource, Learn Prolog Now! Developed by Matthias Vogt, this free program enhances the original website by adding several useful features.

One of the main features of Learn Prolog Now! Enhanced is the embedded Swish IDE (SWI-Prolog), which allows users to write and run Prolog code directly within the browser. This eliminates the need for users to install a separate IDE or compiler, making it convenient for beginners who are just starting to learn Prolog.

In addition to the embedded IDE, the add-on also provides syntax highlighting for code snippets, making it easier to read and understand the Prolog syntax. Furthermore, it offers keyword and semantic highlighting, which helps users identify and differentiate between different elements of the code.

Overall, Learn Prolog Now! Enhanced is a valuable tool for anyone who wants to learn Prolog. It improves the original Learn Prolog Now! website by adding essential features such as an embedded IDE and syntax highlighting. The add-on is free to use and can be accessed through the Chrome browser. Please note that this is a personal project and not an official extension endorsed by the authors of Learn Prolog Now.
