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:
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.
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
(Work in progress :P)
