Compact Compiler

Overview

MyCompiler is a simple yet powerful compiler built using Java and ASM (Abstract Syntax Tree). It translates a custom programming language into executable bytecode. This project aims to provide a basic understanding of how compilers work, from lexical analysis to code generation.

Features

• Lexical Analysis: Tokenizes the input source code.
• Syntax Analysis: Parses tokens into an Abstract Syntax Tree (AST).
• Semantic Analysis: Ensures semantic correctness of the AST.
• Code Generation: Converts the AST into executable bytecode using ASM.
• Error Handling: Provides meaningful error messages for syntax and semantic errors.

Installation

Clone the repository:

  git clone https://github.com/d3v-26/Compiler-PLP-Project.git
  cd Compiler-PLP-Project

Import the Compiler-PLP-Project Folder into Any Java Editor of your choice.

Navigate to CodeGenTests2.java file inside main/src/edu/ufl/cise/plpfa22/ folder.

You can find various test cases on each piece of code being compiled using compile function.

You can also define Custom test of the following signature

    @DisplayName("Apt Name")
	@Test
	public void customTestFunction(TestInfo testInfo) throws Exception {
		String input = """
				## Your Custom Code
				""";
		
		String shortClassName = "prog";
		String JVMpackageName = "edu/ufl/cise/plpfa22";
		List<GenClass> classes = compile(input, shortClassName, JVMpackageName);		
		Object[] args = new Object[1];  
		String className = "edu.ufl.cise.plpfa22.prog";
		loadClassesAndRunMain(classes, className);
		
	}

Run all the test cases following the addition.
