                A complete compiler for a simple language (in less than 150 LoC)
              
          
      View 00_readme.md
  
      
    This project is a tiny compiler for a very simple language consisting of boolean expression.
The language has two constants: 1 for true and 0 for false, and 4 logic gates:
! (not), & (and), | (or), and ^ (xor).
It can also use parentheses to manage priorities.
Here is its grammar in BNF format:
expr ::= "0" | "1"

Code from PyCon India 2019 Keynote Talk

======================================

This code is presented "as is" and represents what was live-coded
during my closing keynote presentation at PyCon India, Chennai,
October 13, 2009.  I have made no changes to the files.

Requires:  Python 3.6+, numpy, pygame

    (This is a translation of the original article in
Japanese by
moratorium08.)
(UPDATE (22/3/2019): Added some corrections provided by the original author.)
Writing your own OS to run on a handmade CPU is a pretty ambitious project, but
I've managed to get it working pretty well so I'm going to write some notes
about how I did it.
