Welcome to the compiler project 2020 starter kit!

=== Structure ===

build.xml (directives for compiling the project using 'ant')

build/ (temp directory created when you build)

examples/ ast/ (examples of AST XMLs representing Java programs)

(more examples to come for each exercise)

schema/ ast.xsd (XML schema for ASTs)

src/ (where all your stuff is going to go)

ast/*
	(Java representation of AST, including XML marshaling & unmarshaling, Visitor interface, and printing to Java. Some files to note:)

	AstXMLSerializer.java
		(for converting ASTs between XML <-> Java classes)

	AstPrintVisitor.java
		(printing AST as a Java program)

	Visitor.java
		(visitor interface)

	Program.java
		(the root of the AST)

cup/
	Parser.cup
	(directives for CUP)

jflex/
	Scanner.jfled
	(directives for JFlex)

Main.java
	(main file, including a skeleton for the command line arguments we will use in the exercises. already does XML marshaling and unarmshaling and printing to Java)

Lexer.java
	(generated when you build)

Parser.java
	(generated when you build)

sym.java
	(generated when you build)	

tools/* (third party JARs for lexing & parsing and XML manipulation)

mjava.jar (the build)

README.md (<-- you are here)

=== Compiling the project === ant

=== Cleaning === ant clean

=== From AST XML to Java program === java -jar mjavac.jar unmarshal print examples/BinaryTree.xml res.java

=== From AST XML to... AST XML === java -jar mjavac.jar unmarshal marshal examples/BinaryTree.xml res.xml

=== From AST XML to... AST XML, Renaming a variable === java -jar mjavac.jar unmarshal rename var inputProg.xml outputProg.xml

=== From AST XML to... AST XML, Renaming a method === java -jar mjavac.jar unmarshal rename method inputProg.xml outputProg.xml

=== From AST XML to LLVM code file === java -jar mjavac.jar unmarshal compile inputProg.xml out.ll

=== From AST XML to output txt file: OK or ERROR === java -jar mjavac.jar unmarshal semantic inputProg.xml out.txt (the list of the checks can be found in the file HW3Overview.pdf)

=== From minijava code to AST XML === java -jar mjavac.jar parse marshal inputProg.java out.xml

=== From minijava code to runing the program === java -jar mjavac.jar parse compile inputProg.java out.ll lli out.ll (provided you can run an LLVM file on your macheine)
