Hydrogen Compiler A lightweight, modular compiler for a custom programming language, built using C++, CMake, and assembly.

Overview Hydrogen Compiler is a personal project developed to deepen understanding of compiler design and systems programming. It encompasses all major stages of compilation, including lexical analysis, parsing, semantic analysis, and code generation. The project demonstrates proficiency in C++, build systems, and low-level programming concepts.

Features Lexical Analysis: Tokenizes source code into meaningful symbols.

Parsing: Constructs an Abstract Syntax Tree (AST) from tokens.

Semantic Analysis: Performs type checking and scope resolution.

Code Generation: Translates AST into assembly code.

Modular Design: Each compiler stage is implemented as a separate module for clarity and maintainability. GitHub

Technical Stack Languages: C++, C, Assembly

Build System: CMake

Tools: NASM (Netwide Assembler), GNU LD (Linker)

Getting Started Prerequisites C++17 compatible compiler

CMake 3.10 or higher

NASM assembler

GNU LD linker

Build Instructions bash Copy Edit git clone https://github.com/aashish1601/hydrogencompiler.git cd hydrogencompiler mkdir build cd build cmake .. make The compiled executable will be located in the build/ directory. GitHub

Sample Code A sample Hydrogen source file (test.hy) is provided to demonstrate the compiler's capabilities. GitHub

Project Structure src/: Source code for compiler modules.
