awk-jvm

a toy jvm in awk, based on this tutorial: https://zserge.com/posts/jvm/

notes

• this requires gawk, because of functions and the builtin

  strtonum

• since none of the awks can read binary, you first need to pipe the classfile through hexdump
  • example (see run.sh):

    javac Add.java && hexdump -v -e '/1 "%01u "' Add.class  | awk -f jvm.awk

what can it do?

• not a lot (eg. call methods and basic operations, see Add.java)
