README
Chamomile is a Java Virtual Machine class file assembler and disassembler.
Installation
Maven
```xml
jitpack.io
https://jitpack.io
com.github.wdestroier
chamomile
1.0.0
```
Gradle
```kotlin
repositories {
maven("https://jitpack.io")
}

}
```
Demonstration
Assemble a list of instructions
```java
var assembler = new SinglePassAssembler();
var bytecode = assembler.assemble(List.of(
new Iconst1Instruction(),
new I2lInstruction(),
new AconstNullInstruction(),
new PopInstruction(),
new Fconst2Instruction(),
new F2lInstruction(),
new LaddInstruction(),
new InvokestaticInstruction(InstructionFactory.instance.getOpcode(
InvokestaticInstruction.class), 12)
));
System.out.println(Arrays.toString(bytecode));
```
Output
```txt
[4, 133, 1, 87, 13, 140, 97, 184, 0, 12]
```
Disassemble an array of "unsigned bytes"
```java
var disassembler = new LinearSweepDisassembler();
var bytecode = new short[] { 4, 133, 1, 87, 13, 140, 97, 184, 0, 12 };
var instructions = disassembler.disassemble(bytecode);
instructions.stream()
.map(instruction -> InstructionFactory.instance.getMnemonic(instruction.getOpcode()))
.forEach(System.out::println);
```
Output
```txt
iconst_1
i2l
aconst_null
pop
fconst_2
f2l
ladd
invokestatic
```
