Software

Compiler (.jack -> .vm)

usage: python Software/Compiler/main.py [options] source[.jack]
        sourceFile(s) may be file or directory.
options:
        -m mutes status messages
        -x creates syntax analysis xml file

VM Translator (.vm -> .asm)

usage: python Software/VMTranslator/main.py [options] source[.vm]
        sourceFile(s) may be file or directory.
options:
        -m mutes status messages
        -c writes vm commands as comments in .asm file
        -b doesn't generate bootstrap code
        -l creates source.debug with adjusted line numbers

Assembler (.asm -> .hack)

usage: python Software/assembler.py sourceFile[.asm]
options:
        -m mutes status messages
        -p prints output to stdout

Project 13

A list of all additions and modifications made outside the domain of the course.

• Add modulus functionality to jack with Math.mod() and make the compiler properly interpret the % symbol
• Add pseudo-random number generation to jack (via a linear congruential generator) with Math.seedRandom(), Math.rand(), and Math.randRange()
• Add >=, <=, ~=, and == to the legal jack comparisons (the latter is equivalent to '=')
• Add break statements for while loops
