Intro

There are two versions of assignments(Java or C++) for the CS143-Compiler course, this repo is my Java-version solution.

Course resources:

• This course is available in bilibili.

• You can download the student-dist in edx.org.

Here are my notes:

• Lexical Analysis
• Parsing

PA

PA2J

This assignment is to write a lexical analyser for COOL, using jlex(Java).

By the way, the jlex framework is a bit outdated, you can install jflex to replace it:

> brew install jfelx
> apt-get install jfelx

Generate lexer:

> jflex --jlex cool.lex
> make lexer
> make dotest

To test if the lexer generated works, you can run diff.sh which compares the output of our own lexer and the standard lexer(./bin/lexer) with all cool files in ./examples as input:

> ./diff.sh
