Cool-Compiler

An implementation of the "Classroom Object-Oriented Language" compiler for CS143 on Stanford's open courseware

The files in this directory can get pretty messy, so here is a basic tour:

PA2J: Lexical Analyzer

This directory contains the classes and flex file used by JFlex to create a lexer.

-cool.lex: JFlex input file -CoolLexer.java: File that contains generated flex file, along with some extra boilerplate for incorporating lexer with other created classes. -pa1-grading.perl: Automated script for grading accuracy of lexer

input "make lexer" to generate the lexer files.

PA3J: Syntax Analyzer/Parser Generator

This directory contains all the files for Cup, a java-based parser generator.

-cool.cup: Grammar Specification for Cup parser generator The result of running cool is a number of classes containing the various features of the language.

Run "make parser" to generate the parser files.

#PA4J: Semantic Analyzer

This directory contains a collection of all classes prodeced by the parser, and some utility classes used to perform semantic analysis upon target *.cl files.

-cool-tree.java: Collection of all Non-Terminal elements for the language -ClassTable.java: A utility data structure for storing classes and analyzing inheritance heirarchies -TreeConstants.java: A collection of AbstractSymbol classes used for type analysis between Non-Terminal classes

#PA5J: Code Generation
