Blueprints Access To GConfig

This plugin provides access from blueprints to the data that lives in the Unreal Engine 4 .ini files.

Whilst I was an engineer at Epic Games, I worked a lot on the Config Cache (The ini system). The Config Cache is a core part of the engine and is used by almost every module in one way or another. E.g. To enable voice in your project, you would have had to make a config change to enable this. The Engine’s Online Voice interface would pick it up like so:

GConfig->GetBool(TEXT(“OnlineSubsystem”), TEXT(“bHasVoiceEnabled”), bHasVoiceEnabled, GEngineIni)

In code this is easily accessibile through GConfig. A quick find in the 4.26 source shows that there are ~2700 references to this. However, as far as I can see, there has been no exposure of the common GConfig functionality to Blueprints. That is where this plugin comes in.

Given that the GConfig system allows the developer to access important config information, I have exposed the most basic functionality via this plugin. These have been categorised into three categories: Getters, Setters, and Misc.
