-# BadassPascal
-### This code came from my undergrad course project for compiler principles in 2015, although I did minimum bug fixes on this recently, this code still can not be considered as efficient nor even readible by any means because a lot of hacks were used to make it work and the writing doesn't confrom to a stable coding style either. However, it is something that I was proud of at that time.
+# AwesomePascal
+
+Another PL/0 language (https://en.wikipedia.org/wiki/PL/0) compiler and debugger that is written in C++.   
+
+## Introduction
+
+This code came from my undergrad course project for compiler principles in 2015. The code quality is beyond horrible but it's some of my earliest big projects.
+
+## Architecture
+- The compiler uses **SLR(1)** parsing. The grammar is hard-coded in the form of an LR parsing table (`states`) and the FOLLOW set (`follows`) which is initialized in `initStates()` function.
+- The compiler was written from the ground up **without any third-party libraries** except the standard C++ library.
+- It contains:
+  - A lexer (`GETSYM()` function) that processes the input into tokens and literals while constructing a symbol table
+  - A parser (`BLOCK()` function) that uses shift/reduce-parsing to generate the target code (pseudo-assembly)
+  - An interpreter (`INTERPRET()` function) that executes the pseudo-assembly code.
+
+##  Build 
 
-Another PL/0 language (https://en.wikipedia.org/wiki/PL/0) compiler and debugger written in C++.   
-  
 Supported Environments:   
-MSVC project: BadassPascal.sln  
-GNU C++/Clang: compile BadassPascal.cpp directly  
->e.g.  
->`$ g++ -O3 BadassPascal.cpp -o BP`  
+- MSVC project: AwesomePascal.vcxproj 
+- GNU C++/Clang: compile AwesomePascal.cpp directly  
+
+## Examples
+- InsertionSort.pas: A simple program that takes 5 integers and sorts them in descending order.
+- NumericExpr.pas: A simple program that contains numerical expressions and control flow. 
+- 
+## Usage
+
+>`$ g++ -O3 -DNDEBUG AwesomePascal.cpp -o BP`  
 >`$ ./BP InsersionSort.pas`
