Deen Programming Language

A simple language for efficient software

Deen - a statically-typed compiling programming language inspired by languages like C, C++, Zig, and Rust.

It provides tools for system programming, including: structures, C-like enums with supported functions, type definitions, backward compatibility with C, pointers, recursion, and more.
See official documentation here: Deen Documentation

⚠️ The project is currently under active development and may be unstable.

• ⚡ Simplicity. The language syntax is easy to read and write.
• 🚀 Fast. The compiler uses LLVM as a backend for the best performance.
• ✨ Clean. Nothing superfluous - just basic tools for everything.
• 🌐 Modern. Syntax and mechanics are inspired by Rust and Zig.
• 📑 Strict. Analyzers and checkers will prevent most compile-time errors.
• 🌎 Open Source. You can always participate in the project's development.

• Language: Rust
• Build Systems: Cargo, Make
• Backend: inkwell (LLVM 1.18.6^)
• Errors: thiserror
• Error Reporting: miette, colored
• Command Line Interface: clap

The project is divided into submodules using a virtual workspace environment:

• deen - main executable module. Combines all submodules into the main process.
• deen-lexer - lexical analyzer. Converts source code into abstract data types (Tokens).
• deen-parser - syntax analyzer. Analyzes and converts tokens into an Abstract Syntax Tree.
• deen-semantic - semantic analyzer. Recursively checks the AST for type and principle matching.
• deen-codegen - code generator. Recursively compiles the AST to an LLVM IR module.
• deen-linker - module linker. Compiles the LLVM IR module to an object file and links it.

1. Install clang, gcc or any other supported C compiler (object file compilation required).
2. Download the latest release from GitHub: Latest Release
3. Unpack it anywhere and add to your PATH variable. Instructions for: Windows, Linux, and macOS
4. Restart your system or environment.

1. Install the Rust Programming Language from the official site.
2. Install LLVM following the official tutorial.
3. Clone this repository: git clone https://github.com/mealet/deen
4. Go to its directory and run: cargo build --release
5. The executable file will be in the target/release folder.

Currently Deen Language has no hosted playground.
You can setup your own playground with isolated docker runners and web code editor.
