Recaf

Recaf is an open-source Java bytecode editor based on Objectweb’s ASM. ASM is a library that abstracts away the constant pool and class-file attributes. Since keeping track of the constant pool or managing proper stack frames are no longer necessary, complex changes can be made with relative ease. With additional features to assist in the process of editing Recaf is the most feature-rich free bytecode editor available.

Libraries used:

• ASM – Class editing abilities
• CFR – Decompilation
• Simple-Memory-Compiler – Recompilation of decompiled code
• JIMFS – Virtual file system
• ControlsFX – Custom controls (Used in pretty much everything)
• RichTextFX – Decompiler code highlighting
• JRegex – Pattern matching for decompiler code highlighting
• minimal-json – Json reading/writing for config storage
• Commonmark – Markdown parsing
• picocli – Command line argument parsing

Changelog v2.21.11
