+# Lillero
+> ### Don't do coremods
-A simple and slim ASM patching framework, allowing to modify block game code.
+Lillero is a lightweight and simple ASM patching framework, empowering you to easily modify block game (byte)code, dunking on all the naysayers who said you absolutely had to use Mixin
## How
-This library provides the core interface: `IInjector`. All patches which implement this interface and are defined as services will be loaded and applied at startup.
+This library provides the core interface, `IInjector`, as well as a small set of utils to make your life easier. All patches should implement `IInjector` and be declared as [services](https://docs.oracle.com/javase/8/docs/api/java/util/ServiceLoader.html).
+
+The following `IInjector` methods *must* be implemented
Some methods must be implemented, specifying which class and method will be patched:
- * `targetClass()` : returns full name of class to patch (such as `net.minecraft.client.Minecraft`)
- * `methodName()` : returns name (Searge obfuscated) of method to patch
- * `methodDesc()` : returns descriptor (arguments and return type) of method to patch
- * `inject(ClassNode clazz, MethodNode method)` : will be invoked providing correct class and method. This is where the actual patching happens
-Some extra methods should also be implemented to help identify your patch:
+ * `targetClass()`: returns the *fully qualified name* of the class to patch (example: `net.minecraft.client.Minecraft`).
+ * `methodName()`: returns the "Searge name" of the method to patch.
+ * `methodDesc()`: returns descriptor (arguments and return type) of method to patch.
+ * `inject(ClassNode clazz, MethodNode method)`: will be invoked providing you the ClassNode and MethodNode you requested. This is where the actual patching will happen.
+
+There's some more optional methods you *don't have to* implement, but really should because they will make your life considerably easier when it's time to debug:
* `name()` : returns patch name
* `reason()` : returns patch description
-To make your classes service providers, a simple text file should be defined under `src/main/resources/META-INF/services` in your mod project: `ftbsc.lll.IInjector`. Inside such file, put full class paths of your patches.
+Finally, you should mark your classes as service providers, by creating a text file called `ftbsc.lll.IInjector` in `src/main/resources/META-INF/services` on your project. Inside, put the fully qualified names of your patches (example: `ftbsc.bscv.asm.patches.TestPatch$TickPatch`).
+
+If you use Gradle (you do) don't forget to add this library as a dependency in your `build.gradle`:
+
+```groovy
+repositories {
+ maven { url = 'https://maven.fantabos.co' }
+}
+dependencies {
+ implementation 'ftbsc:lll:0.0.3'
+}
+```
-To load patches created with this library, a Launch Plugin loader is necessary (such as our [lillero-loader](https://git.fantabos.co/lillero-loader/))
+**You are going to need a loader to use patches created with this library**. You can use our [lillero-loader](https://git.fantabos.co/lillero-loader/) or write your own: as long as it uses `IInjector` as patch interface, it won't break compatibility.
### Example
+The following is an example patch, located at `src/main/java/example/patches/SamplePatch.java`:
```java
-// file src/main/java/example/patches/SamplePatch.java
package example.patches;
import ftbsc.lll.IInjector;
public class SamplePatch implements IInjector {

main.instructions.insert(insnList);
}
}
+```
+
+The patch will crash the game with a NegativeArraySizeException as soon as it's done loading - so you know it's working.
