Jadis is a simple Java bytecode Disassembler written in Rust. The goal of this project is to provide an alternative to the javap command we all know and love.

Please note that Jadis is an educational project. This means that for any serious work, you should consider using the Java disassembler that came with your JDK.

This specific disassembler has been written using the Java Virtual Machine Specification for Java SE 17 edition. You can find the full specification file here: https://docs.oracle.com/javase/specs/jvms/se17/html/index.html

All code in this project has been documented using Rust's automatically generated documentation. Please go to https://jadis.tahar.dev to view this project's documentation.

• Learn how the JVM's bytecode is structured.
• Parse bytecode.
• Display assembly instructions.
• Learn Rust.
• Create a more user-friendly GUI to disassemble class files.

• Use https://github.com/gyscos/Cursive to create a nice terminal GUI.
• Add the ability to execute javac from within Jadis.
• Disassemble multiple files at once.
• View generated assembly code next to written Java code.

Since this project is purely an educational project, I have decided to open-source everything and release it under the MIT license.

All I am asking you is to give me some credit if you end up using (parts of) this code in your own projects.

Happy hacking! 😊
