sample input: main.jack
sample output:main.xml

Dependencies: Python3.5 or higher, Python Module(just sys and os)

output: a .xml file in the same directory as the input .jack file

test case: this code successfully passed all the tests given

1. the compiler only translate single .jack file and the VM translator will handle multiple files problem.
Run this code by: python location/of/compiler.py location/of/input.jack
In my case, for example, it would be: $ python compiler.py ./Square/Square.jack


2. The output will be named input.xml and in the same directory with input file(might overwrite previous input.xml file if you have one
with the same directory of input.jack !!)

This python code has two parts:
1. Simple tokenizer that tokenize each char and convert it to a tuple: ('type',char)

2. A parser class that parse these token according to the logic of jack languages.


The parser uses a counter to represent the current tuple(from part1) that need to be parsed.
Subrountine,varDec,statements(including if,while,do,return,let),expression,term are handled 
with their corresponding syntax, which is also written below each function definition as comment in detail.
