OptiFineDeobf is a tool that deobfuscates individual class files and "extracted"/"mod" OptiFine jars.
It can be used to remap the method and field names in any jar or class file.
Its primary function is to deobfuscate & tweak an srg named OptiFine mod for use in a 1.13+ development environment.
It was made because both simpledeobf and BON2 were unable to deobfuscate OptiFine due to both tools not remapping INVOKEDYNAMIC instruction arguments and BON2's inability to deal with OptiFine's classes in the srg/ folder.

The Forge Dev Jar option applies the following tweaks to the OptiFine jar make it useful as a library to compile against in a forge development environment:
- Discards all classes in
notch/as they would otherwise cause compilation issues (obfuscated classes usingnotchnames and stub classes) - Changes the paths of all classes in
srg/to their proper name (e.g.srg/foo/class1234->foo/SomeClass)
Note that this only creates a library for you to compile against, this doesn't create an OptiFine that can be put in mods/ in a dev environment. For that you'll need to use the dev tweaker (instructions here)
