As per the reply to my comment https://github.com/MinecraftForge/FML/issues/375 I am posting this here I was digging around in the source code directory of Forge to familiarize myself with the various aspects of Forge in order to write a mod whence i found the dump.Registry() in the package cpw.mods.fml.common.registry i have been googling for over 2 hours and the only thing i could find on that was the gitHub issue thread i linked above (in case you didn't or cant view the post above) i found on line 161 what looked to be a system configuration call to some parameter:

        if (Boolean.valueOf(System.getProperty("fml.dumpRegistry", "false")).booleanValue())

however i cant find any reference to that at all in any configuration file (or any other ANSI encoded file for that matter) any where in my minecraft hierarchy. there seems to be a void on the internet concerning this little feature. I would like to be able to dump the game registry for debugging and developing purposes and would like to know how.

Use the

-D<name>=<value>

command line argument to set the values of system properties like

fml.dumpRegistry

.

That was the most helpful thing on that subject i could find also learned a little about the name=value pairs

Thanks
