MiniJava

The repository for Compiler project of a MiniJava Parser Front-end upon ANTLR 4. You can see the pared AST tree using ANTLR TestRig.

Prerequisites

Java Runtime(1.6 or higher)

ANTLR4 : (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface (or visitor) that makes it easy to respond to the recognition of phrases of interest.

$ cd /usr/local/lib
$ curl -O http://www.antlr.org/download/antlr-4.5.3-complete.jar

Getting Started with MiniJava

To simply build from my MiniJava Grammar File, you can use my makefile.

$ cd src
$ make
$ make gui

If you want to clean the whole directory, simple run make clean. If you want to generate results of all sample file, simply run make test. To manually input the program you can try the following instruction, after you have run make and export antlr4 jar file into your \usr\local\lib

$ cd src
$ java org.antlr.v4.gui.TestRig MiniJava goal -tree
$ java org.antlr.v4.gui.TestRig MiniJava goal -gui

In order to see my method invoke check feature, I wrote a wrong sample source file in test\semantic\test.java and you can simply run make mine to see the results. To manually check other file, you can try the following instruction:

$ cd src
$ make
$ javac EvalVisitor.java MiniJava*.java
$ javac Main.java EvalVisitor.java MiniJava*.java
$ java Main < ../test/semantic/test.java
