MyCompiler

Overview

MyCompiler is a simple programming language with its own syntax and parser. This project includes tokenization, parsing, and evaluation of expressions based on a well-defined grammar. The compiler supports variable assignments, conditional statements, and arithmetic operations. Additionally, the compiler also generates assembly code.

Features

• Variable declaration and assignment (let ident = Expr;)
• Arithmetic operations (+, -, *, /)
• Conditional statements (if, elif, else)
• Scope handling with {} blocks
• Program termination with exit(Expr);
• Multiple line comments ( /* comment */ )
• Single line comments ( // comment )

Grammar

The language follows this formal grammar:

Prog      -> Stmt*
Stmt      -> exit(Expr);
          | let ident = Expr;
          | ident = Expr;
          | if (Expr) Scope IfPred
          | Scope
Scope     -> { Stmt* }
IfPred    -> elif (Expr) Scope IfPred | else Scope | ε
Expr      -> Term | BinExpr
BinExpr   -> Expr * Expr  (prec = 1)
          | Expr / Expr  (prec = 1)
          | Expr + Expr  (prec = 0)
          | Expr - Expr  (prec = 0)
Term      -> int_lit | ident | (Expr)

Installation

git clone https://github.com/yourusername/MyCompiler.git
cd MyCompiler
make  # If a Makefile is provided

Usage

To compile and run a source file:

./MyCompiler <source_file>

Compilation and Execution

To compile and run your Hydro Compiler project, follow these steps:

1. Prerequisites

Ensure you have the following installed on your system:

• CMake (version 3.10 or higher)
• GCC or Clang (C++ compiler)
• NASM (Netwide Assembler)
• LD (GNU Linker)

2. Setup Instructions

Step 1: Create a Build Directory

Organize the build files by creating a separate directory:

mkdir build

Step 2: Generate Build Files with CMake

Run the following command to generate the necessary build files:

cmake -S . -B build/

Step 3: Compile the Project

Build the project using CMake:

cmake --build build/

3. Running the Compiler

Step 1: Create a Test File

Create a file named test.hy in the root directory of your project and add the following:

let y = (10 - 2 * 3) / 2;
let x = 3; // first
// first
if (1) {
    x = 1;
} elif (0) {
    x = 2;
} else {
    x = 3;
}

exit(x);

/*
exit(4);
*/
