Pascal Compiler

This repository contains a Java implementation of a compiler for the Pascal programming language. This is my CS course work (Principles of Programming Languages). The first part of the project was to implement the Lexical Analyzer, this part was done with a group member in the class.

Overview

The Pascal Compiler project is a Java program that reads Pascal source code, tokenizes it, and performs syntax checks. It consists of three primary classes: PascalCompiler, SyntaxAnalyzer, and LexicalAnalyzer.

• PascalCompiler is the main class which reads an input file and creates an instance of the SyntaxAnalyzer to tokenize the input and perform syntax checks. It includes syntax checks for various Pascal constructs like if statements, variable declarations, arithmetic operations, and boolean expressions. The compiler can also check for matching parentheses and quotes, and ensure that BEGIN and END keywords match properly in the source code.

• SyntaxAnalyzer is responsible for checking the syntax of the tokenized Pascal code. This class includes various methods for checking the syntax of different Pascal constructs. These methods are used by the PascalCompiler class to verify the syntax of the code.

• LexicalAnalyzer is used to break down the input into individual tokens for further analysis by the SyntaxAnalyzer class. It reads the input character by character and creates a token when it recognizes a valid token in the input.

Usage

Here is an example of how you might run a Java project from the command line:

# Compile the Java files
javac *.java

# Run the PascalCompiler class with the Pascal source code file as input
java PascalCompiler input.pas

Please note that the above is a general example and may not apply directly to this project. It is also possible that the project requires specific versions of Java, JDK11+.
