Jet Lang 🚀

Project development	Current Status

A prototype implementation of the Jet language.

Note
This project is in a very early stage of the development.

The project works only on Windows at the moment, because I decided to play with C++20 modules and try to get the most out of it. We use CMake as our build tool.

What is Jet

A C-like, general-purpose programming language that compiles to a native code (through LLVM IR).

Goals:

• Rust-like syntax
• C++-like feature set (and more)
• Optional garbage collection with no performance compromises
• Extremely fast compile times based on a modular design
• Prototype fast, improve with no limits
• Simplicity is a priority
• Possibility to run in a VM

To read more about the language, see the docs.

Hello world code

fn main {
  println("Hello, {} from Jet!", "World");
}

See more examples here.

Folder structure

The repository is divided into several main and component projects. They are organized in the Projects folder.

Some of the main projects are:

• Compiler App (jetc) - a frontend of the Compiler library,
• Compiler - the base library for compiler implementation. producing an executable.
• Core - a common library providing basic language-related code that is shared among the other main projects.
• Parser - provides the grammar and generates AST for the language.

For a more detailed description of the projects, refer to the Projects directory.

Usage

Download the latest release (if available) and run the following command:

jetc main

This command compiles a file module called main.jet. If you didn't create one yet follow the next steps.

Basic application

Create a file named main.jet with the following content:

fn main {
  println("Hello, {}!", "World");
}

Now run the command mentioned above. The compiler should create a new executable called main.exe. Run the program with:

.\main.exe
