How do I deobfuscate compiled SRG code?

[AutogolazzoJr]

Hello,

I have a .jar file with compiled code and Searge methods/fields. I want to deobfuscate this code, but I don't want to decompile it. I know forge gradle does this process at some point, so I assume there's a tool out there. How can I do this?

Why do you want to do this?

[AutogolazzoJr]

I have compiled SRG code that I want to deobfuscate. I know what I am doing for the most part.

I'll try that out. I'm decompiling optifine, and because I haven't (and don't need to) decompile all of the code, I'd like to deobfuscate both the source that I have and the compiled code. This doesn't really have anything to do with forge, so I declined to state a reason, because it seems like this forum doesn't like giving out help for non-forge reasons. I posted this here because I know forge uses deobfuscation, and this community probably knows the most about minecraft modding as of now.

I have successfully decompiled all but 27 class files of minecraft with optifine installed, and I have a working build (with the class files that I haven't decompiled in a separate library). I'm working on decompiling the rest right now. As for now, I would like to convert those class files from SRG to mcp mappings, so I can convert my source as well. Hope you understand my logic and why I'm doing this.

I don't believe that's the case. Both optifine and minecraft are closed source, but I would guess that the law applies in the same way to optifine as it does to minecraft. Releasing the source code is illegal, but releasing a tool that decompiles and patches optifine should be legal, as well as distributing mods to optifine.

I don't see a license anywhere that gives you permission to mod Optifine.

Have you asked them if you're allowed to? If so please get assistance from them. We won't provide it.
