Script: Write out ASM Code to generate Java class

By Robert Fischer | Published: November 5, 2010

Edit: Updated version of the script here. Here’s a nifty little Groovy script to write out the ASM code to generate a given Java class. #!/usr/bin/env groovy   import org.objectweb.asm.util.ASMifierClassVisitor as V import org.objectweb.asm.ClassReader as R   @Grab(group=’asm’, module=’asm-all’, version=’[3.3,)') private class JustHereForGrab {}   new R(new File(this.args[0]).newInputStream()).accept(new V(new PrintWriter(System.out)), 0) You will have to [...]

Open Source Journaling: Cornerstone

By Robert Fischer | Published: February 6, 2009

I was a bit fried and looking to escape from work, so I played around with Cornerstone a bit tonight. The key focus right now has been the parser of Cornerstone, which is written in Scala. In Cornerstone, there are what I’m calling the “mirror operators”[1]. Like OCaml, Haskell, and Scala, the user can define [...]
