MCModDeobf is a program that I have made for all minecraft developers. The program is used to decompile and then de-obfuscate any Minecraft code (e.g. The minecraft.jar, Minecraft mods or anything else that is minecraft obfuscated code). At the moment it uses procyon java decompiler (found here) but in the future there will be support for multiple decompilers and maybe even adding your own. After the code is decompiled it use some code I wrote to de-obfuscate the java classes to readable java.
At the moment this is still beta and has some problems like how the config is downloaded from the internet (if your offline you can't use it, because it deletes and re-downloads the config after every launch (to be fixed)), I did have another post for this program but I thought I'd make a new one cause it's really not the same program now cause of the additional features that are coming.
I'm sorry but the download link is a adf.ly all you programmers understand why I use adf.ly don't you
This is open source so go ahead and go break my code if you want over at https://github.com/TheGeekyGuy101/MCModDeobf if there are any bugs anyone finds please ever post them in the comments below or post them on the github issue tracker.
Please remember that this is still beta and there is a better Gui and additional features coming so keep an eye out here.
