The most important part of CS143 are five programming assignments. During these assignments, you will implement a compiler for the Class-Object-Oriented-Language (COOL).

You can follow these instruction to setup your own local develop environment.

Aways read the PA handout and the README under each PA directory first and carefully!

You should read Section 1 - 9 in COOL mannual before writing code.

I admit that it is a little bit hard to get used to writing COOL, but PA1 is a good chance for you to get familiar with COOL syntax and it is very helpful for you to write lexer and parser in the following PAs.

Don't rush to write code. My implementation contains only 200LOC for PA2, and I spent 4-5 hours to learn to use flex and understand the background of COOL.

I recommend you read this lex tutorial thoroughly first.

Then read the Section 10 and Figure 1 in COOL mannul.

I also wrote some simple cool programs to do the unit test, you can check the cool/assignents/PA2/mytests directory for more details.

If you are confident that your lexer is correct, you can use the autograd.sh under the PA2 directory to check. This shell scripts will run the reference lexer and your lexer on the COOL programs under cool/examples directory and compare their output.
