An implementation of the "Classroom Object-Oriented Language" compiler for Compilers course in Shoubra Faculty of Engineering.
The files in this directory can get pretty messy, so here is a basic tour:

This directory contains the classes and code for Lexical Analyzer phase.

This directory contains the classes and code for Parese Tree phase.

1. Install intelliJ IDEA.
2. Install ANTLRv4. Please follow the quickstart guide here, or you can simply install ANTLR from IDEA's plugin manager.
3. Import antlr runtime jar.
4. To connect intellij with ANTRL see this video.
5. Use your terminal to run the program.

• First, create the Token file which contains all the tokens we want to compile and its possible values.
• Press right click and click generate Antlr Recognizer.
• Second, Create controller.java that will test the cool input using tokens and generated files
• Pass the test cases files named (good.cl or bad.cl) as an argument to main.
• If there are no errors, the program will output a sequence of tokens in a file called good.cl-lex, otherwise it will report errors with their line numbers.

• First, create the Token file which contains all the tokens we want to compile and its possible values.
• Create the grammer file and import the token file in it and put all the cool relues
• Press right click and click generate Antlr Recognizer.
• Create the ParseErrorListener class in which you can listen for sentax error
• Create controller.java that will test the cool input using tokens and generated files
• Pass the test cases files named (good.cl or bad.cl) as an argument to main.
• If there are no errors, the program will output a sequence of tokens in a file called good.cl-lex and will write the parse tree in the good-cst file
• Otherwise it will report errors with their line numbers .
