**_As of 1.5.0-beta release, unimplemented features will be added at some point_**

# Usage
* Download the latest jar [**here**](https://github.com/iiiiiiiris/Ambien/releases/latest)
  * The jar ending in `-beta` is the obfuscator itself.
  * The jar ending in `-lib` is an optional library you can use to exclude methods & classes.

**Before using:**
* Ambien MUST be ran with Java 8+
* Ambien should not be used alongside or with other obfuscators.

Run the jar using the `--create-config` argument to create a base config

Then run the Ambien jar using the `-config` argument (including the path to your config)

###### To see all the arguments Ambien offers, you can use the '-help' argument

# Example obfuscation

Example obfuscation of Ambien v1.4.0

## Original

``` java
public static void main(String[] args) {
    AnotherClass.yellow();
    boolean plaaaaaaaay = false;

for (int i = 0; i < 15; ++i) {
        System.out.printf("%b: %d\n", plaaaaaaaay, i);
        plaaaaaaaay = !plaaaaaaaay;
    }
}
```

Full test jar source code can be found [here](./src/test/java/me/iris/testjar)

## Obfuscated

```java
public static void main(String[] args) throws Throwable {
    AnotherClass.yellow();
    boolean plaaaaaaaay = false ^ true;
    int i = 0;

while(i < ((16 | -108 | 0) ^ -101)) {
        byte[] var4 = new byte[]{73, 121, 76, 53, 109, 50, 76, 53, 110, 121, 76, 53, 105, 121, 76, 53, 52, 121, 76, 53, 103, 50, 76, 53, 110, 121, 76, 53};
        System.out.printf(A07cQLY3IyaJGAbxxl5(new String(486kCqNqdnWHTRGJKW21xyGHn05SSE8b5CoJlJHw6Y9hUzd3YCj7qmPGN(var4)), QuVrzlq11JpJxR8B1R7CTzqo6w, 13120), plaaaaaaaay, i);
        boolean var10003;
        if (!plaaaaaaaay) {
            var10003 = true;
            if (((31 | -116 | -22) ^ -37) != ((48 | 50 | -128) ^ 55)) {
            }

boolean var6 = false;
            if (var6) {
            }
        } else {
            var10003 = false;
        }

plaaaaaaaay = var10003;
        ++i;
        if (((-22 | 34 | -124) ^ -124) != ((48 | -2 | 123) ^ -40)) {
        }

boolean var5 = false;
        if (var5) {
        }
    }
}
```
