Big performance issue

[juanmuscaria]

Calling Thread.currentThread().getStackTrace(); causes a big performance drop specially the situation you have multiple objects capable of rendering text making it the main hotspot.

The project is way too big for me to load it and try to find an work around and do some testings

I made a small mixin to patch the method and seems like using a different way to get the calling classes (in this case I'm using WhoCalled) seems to fix the issue, but I don't know how it could be implemented in a more dynamic way

@Pseudo
@Mixin(EmojiFontRenderer.class)
public class MixinEmojiFontRenderer {
    @Shadow
    private static EmojiContext CurrentContext;
    @Overwrite(remap = false)
    public static String updateEmojiContext(String text) {
        if (EmojicordConfig.spec.isAvailable() && EmojicordConfig.RENDER.renderEnabled.get()) {
            EnumSet<EmojiContext.EmojiContextAttribute> attributes = EnumSet.noneOf(EmojiContext.EmojiContextAttribute.class);
            if (WhoCalled.$.isCalledByClass(net.minecraft.client.gui.GuiChat.class)) {
                attributes.add(EmojiContext.EmojiContextAttribute.CHAT_INPUT);
            }
            if (WhoCalled.$.isCalledByClass(net.minecraft.client.gui.GuiNewChat.class)) {
                attributes.add(EmojiContext.EmojiContextAttribute.CHAT_MESSAGE);
            }
            CurrentContext = EmojiContext.EmojiContextCache.instance.getContext(text, attributes);
            return CurrentContext.text;
        } else {
            CurrentContext = null;
            return text;
        }
    }
}
