MicroJava is a high-level programming language, similar, but simpler than Java. Similarly to Java, MicroJava source files are compiled to bytecode, which is then executed by a virtual machine (MicroJava Virtual Machine). MicroJava VM is a simple interpretative emulator.

Commands for generating code

Position inside src folder inside project

• Generating lexer:

java -cp ../lib/JFlex.jar JFlex.Main -d rs\ac\bg\etf\pp1 ..\spec\mjlexer.flex >output.out 2>output.err

• Generating parser:

java -cp ../lib/cup_v10k.jar java_cup.Main -destdir rs\ac\bg\etf\pp1 -parser MJParser -ast rs.ac.bg.etf.pp1.ast -buildtree ..\spec\mjparser.cup >output.out 2>output.err

• Compiling and running the code:

test\program.mj test\program.obj (local file Compiler.java)

• Running with debug option:

-debug test\program.obj (lib mj-runtime-1.1.jar class Run.class)

• Disassmbler:

test\program.obj (lib mj-runtime-1.1.jar lib disasm.class
