Mnemonics - A runtime bytecode generation DSL for Scala

For more info see Mnemonics: Type-safe Bytecode Generation at Run Time.

There are more papers in the docs branch.

Example

Here's an example which generates the + 1 function:

scala> import java.lang.Integer
import java.lang.Integer

scala> val f = ASM[Integer, Integer](param =>
     |             _ ~
     |             param.load ~
     |             method((x: Integer) => x.intValue) ~
     |             bipush(1) ~
     |             iadd ~
     |             method((x: Int) => Integer.valueOf(x)))
f: java.lang.Integer => java.lang.Integer = <function1>

scala> f(12)
res0: java.lang.Integer = 13
