ShotaASM

a script mod enables you write asm codes in scripts.

Check Wiki for details.

example :

#compiler javaShota
#import org.apache.logging.log4j.LogManager
#import org.apache.logging.log4j.Logger

System.out.print("Shota Strat his own tests!!! ^o^");
final Logger LOGGER = LogManager.getLogger("Cute shota");
LOGGER.info("Now, i have my own logger!!");

// Change the title
TransformerRegistry.registerASMExplicitTransformer(-99 , 
 (cn) -> {
		for (var mn :cn.methods) {
			var itr = mn.instructions.iterator();
			while (itr.hasNext()) {
				if (itr.next() instanceof LdcInsnNode ldc && ldc.cst instanceof String str && str.startsWith("Cleanroom")) {
					ldc.cst = str + " & Cute Shota";
					LOGGER.info("change the title to {}", ldc.cst);
				}
			}
		}
	}, "net.minecraft.client.Minecraft");

// Arrors is infinite
TransformerRegistry.registerASMExplicitTransformer(-99 , 
 (cn) -> {
		for (var mn :cn.methods) {
			if ("isInfinite".equals(mn.name)){
					mn.instructions.clear();
					mn.visitInsn(Opcodes.ICONST_1);
					mn.visitInsn(Opcodes.IRETURN);
                    var itr = mn.instructions.iterator();
                }
		}
	}, "net.minecraft.item.ItemArrow");
