Luyten

Procyon is a comprehensive development and programming tool that provides its users with a comprehensive set of specialized tools for code generation and analysis.

Besides libraries as core, reflection and expression frameworks, it also packs two other essential elements such as a Java compiler and decompiler.

Since it is dependent on command line tools in order to run, you might prefer something a bit more user-friendly. This is where Luyten comes into play.

In a few words, Luyten is a straightforward piece of software designed to provide you with a streamlined graphical interface for Procyon.

This said, in order to run this app, you will need to make sure that Java is installed on your computers.

You can start taking advantage of Procyon right away by running the standalone JAR file or, if you have patience, by installing it using the other executable file.

Upon launching the app, you will gaze upon a simplistic yet well sorted, typical Java interface. The main window is split into two main and self-explanatory sections: the Structure panel on the left side and the Code panel on the right.

You can either load the files from the File menu or, even faster, you can drag and drop them from their location directly onto Luyten's window.

Once loaded, you can basically view the project's structure and the code associated with each class file. Despite its apparent simplicity, the app bundles more customization features than you would be lead to believe.

For example, the app enables you to take advantage of a Package Explorer Style, to filter out inner class entries, to flatten switch blocks, force explicit imports and types, view synthetic members, exclude nested types, retain redundant casts and enable Unicode replacements.

Even more so, the utility provides you with a small set of useful themes designed to make it as effortless as possible for you to view the code.

Luyten is a useful and efficient Java decompiler GUI for Procyon that does exactly what a tool like this should do, with the added benefit of multiple customization features.
