Hello again r/ReverseEngineering its been over a year since I last shared my pet project, Recaf. Since then it has been almost completely re-written and is continues to make improvements upon what a reversing tool should provide.

2.X aims to make reverse engineering as user friendly as possible. How so? Here's the gist:

1. Automatic compiler integration

   • Dependencies pulled from your current workspace (primary file plus any libraries)

   • Can't find a dependency? Don't worry, Recaf will dynamically generate missing code for you via JPhantom. That's right, you don't even need to specify your missing compile dependencies.

2. Text based bytecode assembler with user friendly features

   • Reference variables not by their index but by their source-code name for maximum legibility

   • Write short bytecode snippets as plain old Java source code, Recaf will translate inline expressions for you

   • See what values are on the stack and in your local variables at any point by selecting the line

   • Verify all your modifications on the fly to prevent time-wasting mistakes

3. Multiple class representations, defaulting to decompiled code

   • View the class in one of 3 decompilers, CFR, FernFlower, or Procyon

   • Context sensitive right-click actions on source code elements

   • Automatically suggest switching decompilers when errors occur in current one

   • Code too obfuscated? Change the class representation to a table to show fields, methods, and class attributes in an organized table while retaining all the context sensitive menu actions

4. Highly configurable search

   • Search for string constants by containment, equality, starts-with, ends-with, or regex

   • You can do the same search types with member references

   • You can also do the same for disassembled instruction text

5. Track changes per each class modified with the ability to revert to a prior state at any time

6. Apply mappings to an obfuscated file from a variety of popular mapping formats

And beyond those points, there's a lot more planned for the future.

I'm always looking for suggestions and bug reports, so do feel free to drop a comment.

Happy reversing and merry Christmas o/
